While separate pieces of research found parents offer toddlers cues to express that they are joking and pretending, and that toddlers and preschoolers understand intentions to joke and pretend, it is not yet clear whether parents and toddlers consider joking and pretending to be distinct concepts. This is important as distinguishing these two forms of non-literal acts could open a gateway to understanding the complexities of the non-literal world, as well as the complexities of intentions in general. Two studies found (...) parents offer explicit cues to help 16- to 24-month-olds distinguish pretending and joking. Across an action play study and a verbal play study parents showed more disbelief and less belief through their actions and language when joking versus pretending. Similarly, toddlers showed less belief through their actions, and older toddlers showed less belief through their language. Toddlers' disbelief could be accounted for by their response to parents' language and actions. Thus, these studies reveal a mechanism by which toddlers learn to distinguish joking and pretending. Parents offer explicit cues to distinguish these intentions, and toddlers use these cues to guide their own behaviors, which in turn allows toddlers to distinguish these intentional contexts.

This video-ethnographic study explores how professional actors and a director at the end of a theatrical rehearsal process coordinate transitions between rehearsed scenes. This is done through the development and use ofcues, that is, ‘signals for action’. The aim is to understand how cues are developed and how timing in transitions is achieved by using the designed cues. Work on three different scene transitions is analysed using multimodal Conversation Analysis. The results show that cueing is a central tool for developing (...) well-timed transitions, and how cues serve different purposes in the developing performance. There is no prior plan for how to achieve timely transitions. In all the analysed examples, it is an actor who must produce or act on the given cue who insists on its precise definition, followed by a negotiation on candidate cues, confirmation and specifying the cue. It is also actors who are primarily responsible for the timing of transitions, and the timing is solved through an interplay of clear-cut and embodied actions that allow for temporal variance. Cues are reflexively linked to actors’ observation and interpretation of other actors’ actions, which prevents a mechanical determination of timing in scene transition. (shrink)

ABSTRACTSpatial cueing paradigms are popular tools to assess human attention to emotional stimuli, but different variants of these paradigms differ in what participants’ primary task is. In one variant, participants indicate the location of the target, whereas in the other they indicate the shape of the target. In the present paper we test the idea that although these two variants produce seemingly comparable cue validity effects on response times, they rest on different underlying processes. Across four studies using both variants (...) and manipulating the motivational relevance of cue content, diffusion model analyses revealed that cue validity effects in location tasks are primarily driven by response biases, whereas the same effect rests on delay due to attention to the cue in identification tasks. Based on this, we predict and empirically support that a symmetrical distribution of valid and invalid cues would reduce cue validity... (shrink)

The traditional distinction between social robots and service robots is gradually being eroded in the design, planning and public presentation of physically embodied artificial intelligence. The paper is mainly concerned with two case studies: a service robot named Spot, from Boston Dynamics, and two social robots named Kaspar and Zeno, advertised as useful therapeutic tools for children in the autistic spectrum. The discussion centers on three key factors that play a role in the affective responses robots may elicit in (...) the public: 1) the “uncanny valley effect,” i.e., the cognitive and affective dissonance that may be provoked by machines that are very close to reaching lifelike appearance, but fail to replicate it with respect to behavior, fine motor skills or perceptual cues. 2) the capacity to evoke affective responses thanks to the symbolic connotations that may be associated with the robot’s appearance. 3) The relevance of situational and contextual factors. -/- The paper reaches three conclusions: 1) producers sometimes fail to consider carefully the symbolic connotations that may be associated with the design chosen for their robots. 2) The context in which robots are meant to be used ought to play a more significant role in a fair-handed and pluralistic approach to robot production. 3) it is to be hoped that producers, in collaboration with psychologists and philosophers of emotion, extend their understanding of affectivity beyond the theories of basic emotions upon which they mostly rely. It is important and urgent to reflect on the relevance of social context with respect both to emotion recognition and to the affective response of the public. (shrink)

Findings suggest a positive impact of bilingualism on cognition, including the later onset of dementia. However, it is not clear to what extent these effects are influenced by variations in attentional control demands in response to specific task requirements. In this study, 20 bilingual and 20 monolingual older adults performed a task-switching task under explicit task-cuing vs. memory-based switching conditions. In the cued condition, task switches occurred in random order and a visual cue signaled the next task to be performed. (...) In the memory-based condition, the task alternated after every second trial in a predictable sequence without presenting a cue. The performance of bilinguals did not vary across experimental conditions, whereas monolinguals experienced a pronounced increase in response latencies and error rates in the cued condition. Both groups produced similar switch costs and mixing costs, but bilinguals produced them with lower response latencies. The cognitive benefits of bilingualism seem not to apply to executive functions per se but to affect specific cognitive processes that involve task-relevant context processing. The present results suggest that lifelong bilingualism could promote in older adults a flexible adjustment to environmental cues, but only with increased task demands. However, due to the small sample size, the results should be interpreted with caution. (shrink)

Planar cell polarity, the polarization of cells within the plane of the epithelium, orthogonal to the apical‐basal axis, is essential for a growing list of developmental events, and – over the last 15 years – has evolved from a little‐studied curiosity in Drosophila to the subject of a substantial research enterprise. In that time, it has been recognized that two molecular systems are responsible for polarization of most tissues: Both the “core” Frizzled system and the “global” Fat/Dachsous/Four‐jointed system produce molecular (...) asymmetry within cells, and contribute to morphological polarization. In this review, we discuss recent findings on the molecular mechanism that links “global” directional signals with local coordinated polarity. (shrink)

Luminance and color are strong and self-sufficient cues to pictorial depth in visual scenes and images. The present study investigates the conditions Under which luminance or color either strengthens or overrides geometric depth cues. We investigated how luminance contrasts associated with color contrast interact with relative height in the visual field, partial occlusion, and interposition in determining the probability that a given figure is perceived as ‘‘nearer’’ than another. Latencies of ‘‘near’’ responses were analyzed to test for effects of (...) attentional selection. Figures in a pair were supported by luminance contrast or isoluminant color contrast and combined with one of the three geometric cues. The results of Experiment 1 show that luminance contrasts associated with hue, when it does not interact with other hues, produces the same effects as achromatic luminance contrasts: The probability of‘‘near’’ increases with luminance contrast while the latencies for ‘‘near’’ responses decrease. Partial occlusion is found to be a strong enough pictorial cue to support a weaker red luminance contrast. Interposition cues lose out against cues of spatial position and partial occlusion. The results of Experiment 2, with isoluminant displays of varying color contrast, reveal that red color contrast on a light background supported by any of the three geometric cues wins over green or white supported by any of the three geometric cues. On a dark background, red color contrast supported by the interposition cue loses out against green or white color contrast supported by partial occlusion. These findings reveal that color is not an independent depth cue, but is strongly influenced by luminance contrast and stimulus geometry. Systematically shorter response latencies for stronger ‘‘near’’ percepts demonstrate that selective visual attention reliably detects the most likely depth cue combination in a given configuration.

We investigate the timing of pre-answer inbreaths in order to shed light on the time course of response planning and execution in conversational turn-taking. Using acoustic and inductive plethysmography recordings of seven dyadic conversations in Dutch, we show that pre-answer inbreaths in conversation typically begin briefly after the end of questions. We also show that the presence of a pre-answer inbreath usually co-occurs with substantially delayed answers, with a modal latency of 576 vs. 100 ms for answers not preceded by (...) an inbreath. Based on previously reported minimal latencies for internal intercostal activation and the production of speech sounds, we propose that vocal responses, either in the form of a pre-utterance inbreath or of speech proper when an inbreath is not produced, are typically launched in reaction to information present in the last portion of the interlocutor's turn. We also show that short responses are usually made on residual breath, while longer responses are more often preceded by an inbreath. This relation of inbreaths to answer length suggests that by the time an inbreath is launched, typically during the last few hundred milliseconds of the question, the length of the answer is often prepared to some extent. Together, our findings are consistent with a two-stage model of response planning in conversational turn-taking: early planning of content often carried out in overlap with the incoming turn, and late launching of articulation based on the identification of turn-final cues.

The main focus of the paper is the role of listeners’ emotion-relevant characteristics and musical expertise in the granularity of affective responses to music. Another objective of the study is to test the consistency of the granularity of affect that is perceived in music and/or experienced in response to it. In Experiment 1, 91 musicians and nonmusicians listened to musical excerpts and grouped them according to the similarity of the affects they experienced while listening. Finer grouping granularity was found (...) in musicians and high rumination scorers. Male musicians with above-median scores in rumination produced a larger number of clusters than the other male participants. Experiment 2 that engaged 23 participants demonstrated moderate consistency with which listeners grouped affects that they perceived in music and affects they experienced while listening to music. The study suggests that affective responses to music are subject to individual differences in musical expertise and rumination. Affects perceived in music and felt in response to it seem to be categorized with reference to the common principles. However, the cues that are used in such instances of categorization seem to be different. The paper encourages further research on the importance of listeners’ personal characteristics for the affective responses to music. (shrink)

ABSTRACTIn two experiments, we examined the resolution of confidence judgments in syllogistic reasoning and their heuristic bases. Based on the assumptions of Koriat's Self-Consistency Model of confidence, we expected the confidence judgments to be related to conclusion consensuality, reflecting the role of consistency as a heuristic cue to confidence. In Experiment 1, the participants evaluated 24 syllogisms with conclusions that varied with respect to validity and consensuality. In Experiment 2, the participants produced conclusions to 64 pairs of premises. The correlation (...) between confidence and reasoning accuracy was low. In both experiments confidence was related to the consensuality of the responses. For consensually correct items, correlation between confidence and accuracy was positive; however, for consensually incorrect items it was negative. In Experiment 2, confidence was lower for syllogisms with higher response cardinality, or syllogisms that elicited a greater variety of conclusions. (shrink)

Deception scholars have argued that increasing the liar’s cognitive system artificially can produce deception cues. However, if too much load is imposed the truth tellers’ performance can also be impaired. To address this issue, we designed a veracity task that incorporated a secondary task to increase cognitive load gradually. Also, because deception has been associated with activity in the inferior frontal cortex (IFC), we examined the influence of transcranial direct current stimulation of the IFC on performance. During stimulation, participants truthfully (...) or deceptively indicated whether each of a number of statements shown on screen was true or not. Higher load decreased recall but not general compliance or response times (RTs). Truthful trials yielded higher compliance rates and faster RTs than deceptive trials except for the highest load level. Anodal right stimulation decreased compliance in truthful trials when participants were not overloaded. Truth telling was more vulnerable to cognitive load and tDCS than lying. (shrink)

Only in recent years have developmental psychologists begun advocating and exploring dual-process theories and their applicability to cognitive development. In this paper, a dual-process model of developments in two processing systems—an “analytic” and an “experiential” system—is discussed. We emphasise the importance of “metacognitive intercession” and developments in this ability to override experiential processing. In each of two studies of sunk cost decisions, age-related developments in normative decisions were observed, as were declines in the use of a “waste not” heuristic. In (...) the second study, children and adolescents were presented with arguments for normative and non-normative sunk cost decisions. Following argument evaluation, participants were re-presented the original problems and a set of novel, transfer problems. Results indicated that post-argument improvements were most apparent during adolescence. Age-related improvements were most noticeable on the transfer problems. In general, the findings suggest that the ability to metacognitively intercede (i.e., reflect on arguments; inhibit experientially produced responses) emerges towards middle adolescence. However, even by the end of adolescence, in the absence of significant contextual cues and motivation, this ability is infrequently utilised. (shrink)

In order to improve our understanding of the components that reflect functionally important processes during reward anticipation and consumption, we used principle components analyses (PCA) to separate and quantify averaged ERP data obtained from each stage of a modified monetary incentive delay (MID) task. Although a small number of recent ERP studies have reported that reward and loss cues potentiate ERPs during anticipation, action preparation, and consummatory stages of reward processing, these findings are inconsistent due to temporal and spatial overlap (...) between the relevant electrophysiological components. Our results show three components following cue presentation are sensitive to incentive cues (N1, P3a, P3b). In contrast to previous research, reward‐related enhancement occurred only in the P3b, with earlier components more sensitive to break‐even and loss cues. During feedback anticipation, we observed a lateralized centroparietal negativity that was sensitive to response hand but not cue type. We also show that use of PCA on ERPs reflecting reward consumption successfully separates the reward positivity from the independently modulated feedback‐P3. Last, we observe for the first time a new reward consumption component: a late negativity distributed over the left frontal pole. This component appears to be sensitive to response hand, especially in the context of monetary gain. These results illustrate that the time course and sensitivities of electrophysiological activity that follows incentive cues do not follow a simple heuristic in which reward incentive cues produce enhanced activity at all stages and substages.

The ability to detect and respond to chemosensory threat cues in the environment plays a vital role in survival across species. However, little is known about which chemical compounds can act as olfactory threat signals in humans. We hypothesized that brief exposure to putrescine, a chemical compound produced by the breakdown of fatty acids in the decaying tissue of dead bodies, can function as a chemosensory warning signal, activating threat management responses (e.g., heightened alertness, fight-or-flight responses). This hypothesis (...) was tested by gaging people’s responses to conscious and non-conscious exposure to putrescine. In Experiment 1, putrescine increased vigilance, as measured by a reaction time task. In Experiments 2 and 3, brief exposure to putrescine (vs. ammonia and a scentless control condition) prompted participants to walk away faster from the exposure site. Experiment 3 also showed that putrescine elicited implicit cognitions related to escape and threat. Experiment 4 found that exposure to putrescine, presented here below the threshold of conscious awareness, increased hostility toward an out-group member. Together, the results are the first to indicate that humans can process putrescine as a warning signal that mobilizes protective responses to deal with relevant threats. The implications of these results are briefly discussed. (shrink)

The debate about the appropriate standards for upstream corporate social responsibility of multinational corporations has been on the public and academic agenda for some three decades. The debate originally focused narrowly on “contract responsibility” of MNCs for monitoring of upstream contractors for “sweatshop” working conditions violating employee rights. The authors argue that the MNC upstream responsibility debate has shifted qualitatively over time to “full producer responsibility” involving an expansion from “contract responsibility” in three distinct dimensions. First, there is an expansion (...) of scope from working conditions to human rights and social and environmental impacts broadly defined. Second, there is expansion in depth of this broader responsibility to the whole upstream supply chain without regard to contracting status. Upstream responsibility now includes all suppliers, including direct contractors and the chain of suppliers to such contractors. Finally, the change in CSR scope and depth has led to an evolution of CSR management practice. (shrink)

Theories of sentence production that involve a convergence of activation from conceptual‐semantic and syntactic‐sequential units inspired a connectionist model that was trained to produce simple sentences. The model used a learning algorithm that resulted in a sharing of responsibility (or “division of labor”) between syntactic and semantic inputs for lexical activation according to their predictive power. Semantically rich, or “heavy”, verbs in the model came to rely on semantic cues more than on syntactic cues, whereas semantically impoverished, or “light”, verbs (...) relied more on syntactic cues. When the syntactic and semantic inputs were lesioned, the model exhibited patterns of production characteristic of agrammatic and anomic aphasic patients, respectively. Anomic models tended to lose the ability to retrieve heavy verbs, whereas agrammatic models were more impaired in retrieving light verbs. These results obtained in both sentence production and single‐word naming simulations. Moreover, simulated agrammatic lexical retrieval was more impaired overall in sentences than in single‐word tasks, in agreement with the literature. The results provide a demonstration of the division‐of‐labor principle, as well as general support for the claim that connectionist learning principles can contribute to the understanding of non‐transparent neuropsychological dissociations.

In our daily lives, we are continually involved in decision-making situations, many of which take place in the context of social interaction. Despite the ubiquity of such situations, there remains a gap in our understanding of how decision-making unfolds in social contexts, and how communicative signals, such as social cues and feedback, impact the choices we make. Interestingly, there is a new social context to which humans are recently increasingly more frequently exposed—social interaction with not only other humans but also (...) artificial agents, such as robots or avatars. Given these new technological developments, it is of great interest to address the question of whether—and in what way—social signals exhibited by non-human agents influence decision-making. The present study aimed to examine whether robot non-verbal communicative behavior has an effect on human decision-making. To this end, we implemented a two-alternative-choice task where participants were to guess which of two presented cups was covering a ball. This game was an adaptation of a “Shell Game.” A robot avatar acted as a game partner producing social cues and feedback. We manipulated robot's cues (pointing toward one of the cups) before the participant's decision and the robot's feedback (“thumb up” or no feedback) after the decision. We found that participants were slower (compared to other conditions) when cues were mostly invalid and the robot reacted positively to wins. We argue that this was due to the incongruence of the signals (cue vs. feedback), and thus violation of expectations. In sum, our findings show that incongruence in pre- and post-decision social signals from a robot significantly influences task performance, highlighting the importance of understanding expectations toward social robots for effective human–robot interactions.

Parents influence the development of their offspring in many ways beyond the transmission of DNA. This includes transfer of epigenetic states, nutrients, antibodies and hormones, and behavioural interactions after birth. While the evolutionary consequences of such nongenetic inheritance are increasingly well understood, less is known about how inheritance mechanisms evolve. Here, we present a simple but versatile model to explore the adaptive evolution of non-genetic inheritance. Our model is based on a switch mechanism that produces alternative phenotypes in response to (...) different inputs, including genes and non-genetic factors transmitted from parents and the environment experienced during development. This framework shows how genetic and non-genetic inheritance mechanisms and environmental conditions can act as cues by carrying correlational information about future selective conditions. Differential use of these cues is manifested as different degrees of genetic, parental or environmental morph determination. We use this framework to evaluate the conditions favouring non-genetic inheritance, as opposed to genetic determination of phenotype or within-generation plasticity, by applying it to two putative examples of adaptive non-genetic inheritance: maternal effects on seed germination in plants and transgenerational phase shift in desert locusts. Our simulation models show how the adaptive value of non-genetic inheritance depends on its mechanism, the pace of environmental change, and life history characteristics. (shrink)

The recent introduction of the concepts of tenderness, vulnerability, and parental care in the field of moral emotions has brought us closer to an understanding of the underlying mechanisms, but has not yet resulted in a systematic evolutionary and proximate analysis. Applying such an analysis, the present article proposes a hypothetical care mechanism that produces different motivational states or moral emotions (e.g., tenderness, sympathy, guilt, moral anger) in response to individuals perceived as vulnerable. The mechanism consists of a care system (...) automatically triggered by vulnerability cues, a system for defense and aggression, and a process of causally attributing changes in the vulnerable object’s well-being. The mechanism may also be useful in explaining moral responses in domains other than harm prevention. (shrink)

Adolescence has been linked to an enhanced tolerance of uncertainty and risky behavior and is possibly connected to an increased response toward rewards. However, previous research has produced inconsistent findings. To investigate whether these findings are due to different reward probabilities used in the experimental design, we extended a monetary incentive delay task by including three different reward probabilities. Using functional magnetic resonance imaging, 25 healthy adolescents and 22 adults were studied during anticipation of rewards in the VS. Differently colored (...) cue stimuli indicated either a monetary or verbal trial and symbolized different reward probabilities, to which the participants were blinded. Results demonstrated faster reaction times for lower reward probabilities in both age groups. Adolescents were slower through all conditions and had less activation on a neural level. Imaging results showed a three-way interaction between age group x condition x reward probability with differences in percent signal change between adolescents and adults for the high reward probabilities while adolescents demonstrated differences for the lowest. Therefore, previous inconsistent findings could be due to different reward probabilities, which makes examining these crucial for a better understanding of adolescent and adult behavior. (shrink)

Multiple acoustic dimensions signal speech categories. However, dimensions vary in their informativeness; some are more diagnostic of category membership than others. Speech categorization reflects these dimensional regularities such that diagnostic dimensions carry more “perceptual weight” and more effectively signal category membership to native listeners. Yet perceptual weights are malleable. When short-term experience deviates from long-term language norms, such as in a foreign accent, the perceptual weight of acoustic dimensions in signaling speech category membership rapidly adjusts. The present study investigated whether (...) rapid adjustments in listeners’ perceptual weights in response to speech that deviates from the norms also affects listeners’ own speech productions. In a word recognition task, the correlation between two acoustic dimensions signaling consonant categories, fundamental frequency and voice onset time, matched the correlation typical of English, and then shifted to an “artificial accent” that reversed the relationship, and then shifted back. Brief, incidental exposure to the artificial accent caused participants to down-weight perceptual reliance on F0, consistent with previous research. Throughout the task, participants were intermittently prompted with pictures to produce these same words. In the block in which listeners heard the artificial accent with a reversed F0 × VOT correlation, F0 was a less robust cue to voicing in listeners’ own speech productions. The statistical regularities of short-term speech input affect both speech perception and production, as evidenced via shifts in how acoustic dimensions are weighted. (shrink)

Clever Hans, the famous horse who was believed to be able to count, is generally cited as the paradigm of the influence of the observer. Psychologist Rosenthal has illustrated this phenomenon with his well-known experiment about ‘bright’ and ‘dull’ maze rats. Hans, however, achieved something much more interesting. Hecould not only read human minds through their bodies: he could also influence his questioners to produce gestures he could read as cues for finding the answer. Hans could make human bodies be (...) moved and be affected, and move and affect other beings and perform things without their owners’ knowledge. The question of ‘influence’ when we read this case becomes therefore far more complicated and interesting. It involves the question of the way bodies can attune, affect and transformeach other. We may follow carefully how scientists of ethological practices create access to the creatures they study, how they are moved by their subjects of interest, and how they give them a chance to be interesting andto articulate other responses. Doing so, we notice that the signs that define subject and object, what talks and what is talked about, subjectivity and objectivity, are redistributed in a new manner. These practices offer a new and pragmatic definition of the body, close to James’s theory of emotions: to have a body is to learn how to feel. (shrink)

The mental lexicon changes across the lifespan. Prior work, aggregating data among individuals of similar ages, found that the aging lexicon, represented as a network of free associations, becomes more sparse with age: degree and clustering coefficient decrease and average shortest path length increases. However, because this work is based on aggregated data, it remains to be seen whether or not individuals show a similar pattern of age-related lexical change. Here, we demonstrate how an individual-level approach can be used to (...) reveal differences that vary systematically with age. We also directly compare this approach with an aggregate-level approach, to show how these approaches differ. Our individual-level approach follows the logic of many past approaches by comparing individual data as they are situated within population-level data. To do this, we produce a conglomerate network from population-level data and then identify how data from individuals of different ages are situated within that network. Though we find most qualitative patterns are preserved, individuals produce associates that have a higher clustering coefficient in the conglomerate network as they age. Alongside a reduction in degree, this suggests more specialized but clustered knowledge with age. Older individuals also reveal a pattern of increasing distance among the associates they produce in response to a single cue, indicating a more diverse range of associations. We demonstrate these results for three different languages: English, Spanish, and Dutch, which all show the same qualitative patterns of differences between aggregate and individual network approaches. These results reveal how individual-level approaches can be taken with aggregate data and demonstrate new insights into understanding the aging lexicon. (shrink)

Poorly saturated colors are closer to a pure grey than strongly saturated ones and, therefore, appear less “colorful”. Color saturation is effectively manipulated in the visual arts for balancing conflicting sensations and moods and for inducing the perception of relative distance in the pictorial plane. While perceptual science has proven quite clearly that the luminance contrast of any hue acts as a self-sufficient cue to relative depth in visual images, the role of color saturation in such figure-ground organization has remained (...) unclear. We presented configurations of colored inducers on grey ‘test’ backgrounds to human observers. Luminance and saturation of the inducers was uniform on each trial, but varied across trials. We ran two separate experimental tasks. In the relative background brightness task, perceptual judgments indicated whether the apparent brightness of the grey test background contrasted with, assimilated to, or appeared equal (no effect) to that of a comparison background with the same luminance contrast. Contrast polarity and its interaction with color saturation affected response proportions for contrast, assimilation and no effect. In the figure-ground task, perceptual judgments indicated whether the inducers appeared to lie in front of, behind, or in the same depth with the background. Strongly saturated inducers produced significantly larger proportions of foreground effects indicating that these inducers stand out as figure against the background. Weakly saturated inducers produced significantly larger proportions of background effects, indicating that these inducers are perceived as lying behind the backgrounds. We infer that color saturation modulates figure-ground organization, both directly by determining relative inducer depth, and indirectly, and in interaction with contrast polarity, by affecting apparent background brightness. The results point towards a hitherto undocumented functional role of color saturation in the genesis of form, and in particular figure-ground percepts in the absence of chromatostereopsis. (shrink)

Every cell, tissue, organ and organism is competent to use signs to exchange information reaching common coordinations and organisations of both single cell and group behavior. These sign-mediated interactions we term biological communication. The regulatory system that works in development, morphology, cell fate and identity, physiology, genetic instructions, immunity, memory/learning, physical and mental disease depends on epigenetic marks. The communication of cells, persistent viruses and their defectives such as mobile genetic elements and RNA networks ensures both the transport of regulatory (...) instructions and the reprogramming of these instructions. But how are the different states of the epigenome orchestrated? The epigenetic pathways respond to various signaling cues such as DNA methylation, histone variants, histone modifications, chromatin structure, nucleosome remodeling, and epigenetic interactions. Epigenetic signals are responsible for the establishment, maintenance and reversal of transcriptional states that are fundamental for the cell's ability to memorize past events, such as changes in the external environment, socio-sphere or developmental cues. External signals trigger changes in the epigenome, allowing cells to respond dynamically. Internal signals direct activities that are necessary for body maintenance, and repairing damaged tissues and organs. With the emergence of epigenetic memory, organisms can fix historical and context dependent impressive experiences. Evolution from now on learnt to learn. Learning means organisms can avoid reproduction of always the same. This is key to adaptation. However, inheritance of acquired characteristics is only one of the many examples of the explanatory power of epigenetics. Behavioral epigenetics demonstrates the way in which environmental and social experiences produce individual differences in behaviour, cognition, personality, and mental health. This book assembles experts to outline the various motifs of all kinds of epigenetic regulation of cells throughout their lives. (shrink)

Basic Emotion theory has had a tremendous influence on the affective sciences, including music psychology, where most researchers have assumed that music expressivity is constrained to a limited set of basic emotions. Several scholars suggested that these constrains to musical expressivity are explained by the existence of a shared acoustic code to the expression of emotions in music and speech prosody. In this article we advocate for a shift from this focus on basic emotions to a constructionist account. This approach (...) proposes that the phenomenon of perception of emotions in music arises from the interaction of music’s ability to express core affects and the influence of top-down and contextual information in the listener’s mind. We start by reviewing the problems with the concept of Basic Emotions, and the inconsistent evidence that supports it. We also demonstrate how decades of developmental and cross-cultural research on music and emotional speech have failed to produce convincing findings to conclude that music expressivity is built upon a set of biologically pre-determined basic emotions. We then examine the cue-emotion consistencies between music and speech, and show how they support a parsimonious explanation, where musical expressivity is grounded on two dimensions of core affect (arousal and valence). Next, we explain how the fact that listeners reliably identify basic emotions in music does not arise from the existence of categorical boundaries in the stimuli, but from processes that facilitate categorical perception, such as using stereotyped stimuli and close-ended response formats, psychological processes of construction of mental prototypes, and contextual information. Finally, we outline our proposal of a constructionist account of perception of emotions in music, and spell out the ways in which this approach is able to make solve past conflicting findings. We conclude by providing explicit pointers about the methodological choices that will be vital to move beyond the popular Basic Emotion paradigm and start untangling the emergence of emotional experiences with music in the actual contexts in which they occur. -/- .

While there is an extensive literature on the tendency to mimic emotional expressions in adults, it is unclear how this skill emerges and develops over time. Specifically, it is unclear whether infants mimic discrete emotion-related facial actions, whether their facial displays are moderated by contextual cues and whether infants’ emotional mimicry is constrained by developmental changes in the ability to discriminate emotions. We therefore investigate these questions using Baby-FACS to code infants’ facial displays and eye-movement tracking to examine infants’ looking (...) times at facial expressions. Three-, 7-, and 12-month-old participants were exposed to dynamic facial expressions of a virtual model which either looked at the infant or had an averted gaze. Infants did not match emotion-specific facial actions shown by the model, but they produced valence-congruent facial responses to the distinct expressions. Furthermore, only the 7- and 12-month-olds displayed negative responses to the model’s negative expressions and they looked more at areas of the face recruiting facial actions involved in specific expressions. Our results suggest that valence-congruent expressions emerge in infancy during a period where the decoding of facial expressions becomes increasingly sensitive to the social signal value of emotions.

In lieu of an abstract, here is a brief excerpt of the content:IntroductionF. S. [email protected] and Richard [email protected] state that there are no sound bites or video clips from classical antiquity is to repeat the obvious. But it is a surprise perhaps to realize how seldom we can recall our field’s most influential scholars even of the very recent past through such now commonplace media. Moreover, the chance to view and hear personal reflections articulated by any such figures about their (...) career, influences, and impact is rare indeed. It was precious opportunities of this type that Pat Thane, Alastair Reid, and Michael Thompson had the foresight to capture from the mid-1980s by developing a video Interviews with Historians series between 1985 and 1996.1 The series was produced by the Publications Department of the Institute of Historical Research at the University of London. In each instance (eventually a total of twenty-eight), a leading historian is interviewed—usually in a studio—by a younger colleague in the same field; three cameras are used, one long shot and one close-up of each participant.2The interview with Sir Moses Finley was one of the first two made (in October 1985) and, as it turned out fortuitously, only months before his sudden death in June 1986 at age 74. The interviewer is Keith Hopkins (a youthful 51), Finley’s one-time graduate student, who had himself just become Cambridge’s professor of ancient history, the position that Finley occupied from 1970 to 1979. They talked in the studio for approximately one hour, and Alastair Reid then edited the master tape with notable skill [End Page 167] to shorten the interview to thirty-five minutes; once both participants had given their approval, the interview was released.3 Meantime, the hour-long U-Matic master tape was archived, but otherwise forgotten. Fortunately, however, in response to inquiries made by Richard Talbert during summer 2013, the Institute proved able to retrieve the tape and—despite its fragility and long outmoded format—to arrange for a successful transfer of the interview to DVD by Soho Broadcast, London.4Our original intention was to offer a transcript of the edited thirty-five-minute version,5 but once the hour-long tape surfaced, we decided instead to offer the interview in its entirety. Our transcript (below, p. 179) inevitably has its limitations and can make no claim to substitute for the video itself.6 It cannot reproduce the unfailingly good-humored atmosphere throughout the interview, nor the range of tones and emphases, nor Finley’s New York accent, nor the marked variations in the pace at which he makes his points, nor of course his constant, characteristic gestures. The variations in pace have influenced how we resolved to punctuate some passages, an unavoidably subjective exercise. Above all, however, we have resisted the recurrent temptation to “clean up” the conversation, so that repetitious, inconsequential, and incomplete remarks are eliminated, and readers are left with a text that more readily approximates to standard written prose.7 Au contraire, our transcript consciously aims to preserve the untidiness and immediacy of the interview; in consequence, very little in the way of repetitive and inconsequential remarks has been omitted.The transcript must be approached, therefore, as the opportunity to listen in on a cordial conversation. One might fairly wonder how far Hopkins had settled in advance with Finley the directions that it might take. No more than minimally, we may suspect, beyond their mutual acknowledgment of the general scope and purpose outlined by the series organizers—hence Hopkins’ unfailing deference towards Finley and his [End Page 168] successive cues to advance the conversation instructively. But recalling the stage where Hopkins asks, “How did you come to cross the Atlantic?” and Finley blithely declines to offer more than the briefest response, we can only speculate whether this was a prearranged rejection of a question which it was reasonable for Hopkins to pose but which Finley preferred not to pursue; or whether Hopkins failed to anticipate quite such a rapid, firm rebuff, and so had to introduce a fresh line of questioning sooner than expected. After all, if Finley had opted to take up the... (shrink)

Congenital amusia in its most common form is a disorder characterized by a musical pitch processing deficit. Although pitch is involved in conveying emotion in music, the implications for pitch deficits on musical emotion judgements is still under debate. Relatedly, both limited and spared musical emotion recognition was reported in amusia in conditions where emotion cues were not determined by musical mode or dissonance. Additionally, assumed links between musical abilities and visuo-spatial attention processes need further investigation in congenital amusics. Hence, (...) we here test to what extent musical emotions can influence attentional performance. Fifteen congenital amusic adults and fifteen healthy controls matched for age and education were assessed in three attentional conditions: executive control, alerting, and orienting while music expressing either joy, tenderness, sadness, or tension was presented. Visual target detection was in the normal range for both accuracy and response times in the amusic relative to the control participants. Moreover, in both groups, music exposure produced facilitating effects on selective attention that appeared to be driven by the arousal dimension of musical emotional content, with faster correct target detection during joyful compared to sad music. These findings corroborate the idea that pitch processing deficits related to congenital amusia do not impede other cognitive domains, particularly visual attention. Furthermore, our study uncovers an intact influence of music and its emotional content on the attentional abilities of amusic individuals. The results highlight the domain-selectivity of the pitch disorder in congenital amusia, which largely spares the development of visual attention and affective systems. (shrink)

The early right anterior negativity (ERAN) in event-related potentials (ERPs) is typically elicited by syntactically unexpected events in Western tonal music. We examined how visual predictive information influences syntactic processing, how musical or non-musical cues have different effects, and how they interact with sequential effects between trials, which could modulate with the strength of the sense of established tonality. The EEG was recorded from musicians who listened to chord sequences paired with one of four types of visual stimuli; two provided (...) predictive information about the syntactic validity of the last chord through either musical notation of the whole sequence, or the word “regular” or “irregular”, while the other two, empty musical staves or a blank screen, provided no information. Half of the sequences ended with the syntactically invalid Neapolitan sixth chord, while the other half ended with the Tonic chord. Clear ERAN was observed in frontocentral electrodes in all conditions. A principal component analysis was performed on the grand average response in the audio-only condition, to separate spatio-temporal dynamics of different scalp areas as principal components and use them to extract auditory-related neural activities in the other visual-cue conditions. The first principal component (PC1) showed a symmetrical frontocentral topography, while the second (PC2) showed a right-lateralized frontal concentration. A source analysis confirmed the relative contribution of temporal sources to the former and a right frontal source to the latter. Cue predictability affected only the ERAN projected onto PC1, especially when the previous trial ended with the Tonic chord. The ERAN in PC2 was reduced in the trials following Neapolitan endings in general. However, the extent of this reduction differed between cue-types, whereby it was nearly absent when musical notation was used, regardless of whether the staves were filled with notes or empty. The results suggest that the right frontal areas carry out the primary role in musical syntactic analysis and integration of the ongoing context, which produce schematic expectations that, together with the veridical expectation incorporated by the temporal areas, inform musical syntactic processing in musicians.

Incidental perceptual memory tests reveal priming when words are generated orally from a semantic cue at study, and this priming could reflect contamination by voluntary retrieval. We tested this hypothesis using a generate condition and two read conditions that differed in depth of processing (read-phonemic vs read-semantic). An intentional word-stem completion test showed an advantage for the read-semantic over the generate condition and an advantage for the generate over the read-phonemic condition, and completion times were longer than in a control (...) test, prior to which there was no study phase. An incidental word-stem completion test showed equivalent priming for the read-semantic and read-phonemic study conditions, despite considerable power, and completion times were no longer than control, indicating that retrieval was involuntary, and insensitive to prior conceptual processing. The generate condition produced less priming than the read conditions, but significant priming nonetheless. The results show that priming from generating can be involuntary and suggest that lexical processes are responsible. They are also the first results conjointly showing a crossed double dissociation, a single dissociation, and a parallel effect across memory tests with identical physical retrieval cues. (shrink)

Little is known about distance processing in patients with posterior brain damage. Although many investigators have claimed that distance estimates are normal or abnormal in some of these patients, many of these observations were made informally and the examiners often asked for relative, and not absolute, distance estimates. The present investigation served two purposes. First, we wanted to contrast the use of distance information in peripersonal space for perceptual report as opposed to visuomotor control in our visual form agnosic patient, (...) DF. Second, we wanted to see to what extent her abilities to process distance cues were dependent on binocular vision, in light of Milner et al.'s (1991) observations of preserved stereopsis in DF, and Dijkerman et al.'s (1996) and Marotta et al.'s (1997) observations that her visual guidance of grasping may be particularly dependent on binocular vision of the target. We hypothesized that DF's visuomotor responses would show normal sensitivity to target distance, while her perceptual estimates would not. In the first experiment, we required DF and two age- and sex-matched control subjects to reach out and grasp black cubes placed at varying distances, or to estimate the distance of the cubes from the hand starting position without making a reaching movement. In the second experiment, we required DF and two age-matched control subjects to point as rapidly and accurately as possible to small LED targets which differed in spatial location, under binocular and monocular conditions. The results showed that, relative to the control subjects, DF's grasping movements produced normal peak velocity-distance scaling-when she reached for blocks which varied in depth or pointed to LED targets which were presented at different distances in depth. In contrast, in the cube experiment, her verbal estimates of object distance were poorly scaled, although they improved slightly under the binocular conditions. The results are discussed in terms of current theories of processing streams in extrastriate visual cortex and the distinction between categorical and coordinate spatial processing. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Journal of Aesthetic Education 39.2 (2005) 36-57 [Access article in PDF] "Being With": The Resonant Legacy of Childhood's Creative Aesthetic Lori A. Custodero Teachers College, Columbia University Introduction...enrichment of the present for its own sake is the just heritage of childhood....1In this paper, the qualities of artistic pursuit exemplified in the musical play of children and the compositional processes of adults provide a context for exploring how "being (...) with" influences teaching and learning. Specifically I propose that "being with" music generates a sense of the aesthetic as we both transform musical materials — timbres, pitches, rhythms, phrases, harmonies — and are transformed by our experiences with them, and that "being with" others as we partake in musical activity often broadens and deepens that experience. In many ways, this is an exploration into why childhood matters, how it functions as a mirror for our adult lives as we experience and revel in the seemingly miraculous moments of aesthetic insight, where the familiar is welcomed with fresh perception and the addition of novelty is greeted as the solution to a previously unfathomable problem. It is also about why children matter, as our responses to their ways of being connect and transform us as adults. In this piece, recorded observations of children's musicality are juxtaposed with first-person accounts of adults' creative processes, revealing contributions to our understanding of artistry-in-action as it is manifested in both the musical and the pedagogical. The Aesthetic in Childhood and Adulthood To be "in the moment" is to encounter the aesthetic — fully engaged in an activity for which one's individual contributions are perceived as vital, aware of surprise relationships between seemingly disparate phenomena, and enveloped by sensory messages of color, sound, and movement meeting personal criteria for beauty. Such experiences exemplify features of artistry, an approach defined by openness to possibility and orientation toward discovery, where cues emanating from involvement in activity are clearly interpreted and utilized, and reflection is an ongoing process informing action. Characterized by a sense of wonder and ability to imagine and invent, the creative worlds of young children have provided a source of artistic genesis cited by composers, performers, psychologists, and educators.2Edith Cobb's thoughtful, groundbreaking account of the relationship between childhood and artistry, The Ecology of Imagination in Childhood, was introduced by Margaret Mead, who highlighted the work's thesis: "that in the imaginative experiences of childhood could be found the essential kernels of the highest forms of human thought."3 The legacy of childhood is universal to our existence; in acknowledging its contributions to ontological and cultural artistry, we can both connect personal histories across the [End Page 36] lifespan and identify characteristic trends across a spectrum of aesthetic rendering.4One trait common to both the child and the creative adult is a focused attentiveness to perceived affordances, that is, materials and human resources accessible in the environment. Acting upon and with these resources,children and artists become aesthetic agents as sensitivity to both experience and milieu combine to produce relevant and innovative outcomes.5 These two interactive dimensions have been described in interviews with composers I have interviewed as "being with the moment" and "being with yourself and at the same time with another" and are operating in the musical play of children, as noted in this description recorded by a mother/student: On Thanksgiving Day, we had a family gathering of sixteen people, five of whom are under the age of eight years. Three-year-old Louise is thrilled to be with her female cousins, who all dress up in ballet-type frilly costumes in order to put on a "show" for the family. Cousin Lily, now eight years old, assumes the role of pianist, while Louise, and five-year-old cousin Amy creatively dance to Lily's improvised accompaniment. Their movements are directly related to Lily's playing, in her fluidity and well as "jumps!" Here, family members serve as catalysts for creative activity — costumes and musical instruments in the environment... (shrink)

Mirrored-self misidentification is the delusional belief that one's own reflection in the mirror is a stranger. In two experiments, we tested the ability of hypnotic suggestion to model this condition. In Experiment 1, we compared two suggestions based on either the delusion's surface features (seeing a stranger in the mirror) or underlying processes (impaired face processing). Fifty-two high hypnotisable participants received one of these suggestions either with hypnosis or without in a wake control. In Experiment 2, we examined the extent (...) to which social cues and role-playing could account for participants' behaviour by comparing the responses of 14 hypnotised participants to the suggestion for impaired face processing (reals) with those of 14 nonhypnotised participants instructed to fake their responses (simulators). Overall, results from both experiments confirm that we can use hypnotic suggestion to produce a compelling analogue of mirrored-self misidentification that cannot simply be attributed to social cues or role-playing.

Observing averted eye gaze results in the automatic allocation of attention to the gazed-at location. The role of the orientation of the face that produces the gaze cue was investigated. The eyes in the face could look left or right in a head-centred frame, but the face itself could be oriented 90 degrees clockwise or anticlockwise such that the eyes were gazing up or down. Significant cueing effects to targets presented to the left or right of the screen were found (...) in these head orientation conditions. This suggests that attention was directed to the side to which the eyes would have been looking towards, had the face been presented upright. This finding provides evidence that head orientation can affect gaze following, even when the head orientation alone is not a social cue. It also shows that the mechanism responsible for the allocation of attention following a gaze cue can be influenced by intrinsic object-based (i.e. head-centred) properties of the task-irrelevant cue.
