Event segmentation theory posits that people segment continuous experience into discrete events and that event boundaries occur when there are large transient increases in prediction error. Here, we set out to test this theory in the context of story listening, by using a deep learning language model (GPT‐2) to compute the predicted probability distribution of the next word, at each point in the story. For three stories, we used the probability distributions generated by GPT‐2 to compute the (...) time series of prediction error. We also asked participants to listen to these stories while marking event boundaries. We used regression models to relate the GPT‐2 measures to the human segmentation data. We found that event boundaries are associated with transient increases in Bayesian surprise but not with a simpler measure of prediction error (surprisal) that tracks, for each word in the story, how strongly that word was predicted at the previous time point. These results support the hypothesis that prediction error serves as a control mechanism governing event segmentation and point to important differences between operational definitions of prediction error.

Filmmakers use continuity editing to engender a sense of situational continuity or discontinuity at editing boundaries. The goal of this study was to assess the impact of continuity editing on how people perceive the structure of events in a narrative film and to identify brain networks that are associated with the processing of different types of continuity editing boundaries. Participants viewed a commercially produced film and segmented it into meaningful events, while brain activity was recorded with functional magnetic resonance imaging (...) (MRI). We identified three degrees of continuity that can occur at editing locations: edits that are continuous in space, time, and action; edits that are discontinuous in space or time but continuous in action; and edits that are discontinuous in action as well as space or time. Discontinuities in action had the biggest impact on behavioral event segmentation, and discontinuities in space and time had minor effects. Edits were associated with large transient increases in early visual areas. Spatial-temporal changes and action changes produced strikingly different patterns of transient change, and they provided evidence that specialized mechanisms in higher order perceptual processing regions are engaged to maintain continuity of action in the face of spatiotemporal discontinuities. These results suggest that commercial film editing is shaped to support the comprehension of meaningful events that bridge breaks in low-level visual continuity, and even breaks in continuity of spatial and temporal location.

Our daily lives unfold continuously, yet our memories are organised into distinct events, situated in a specific context of space and time, and chunked when this context changes (at event boundaries). Previous research showed that this process, termed event segmentation, enhances object-context binding but impairs temporal order memory. Physiologically, peaks in pupil dilation index event segmentation, similar to emotion-induced bursts of autonomic arousal. Emotional arousal also modulates object-context binding and temporal order memory. Yet, these two (...) critical factors have not been systematically studied together. To address this gap, we ran a behavioural experiment using a paradigm validated to study event segmentation and extended it with emotion manipulation. During encoding, we sequentially presented greyscale objects embedded in coloured frames (colour changes defining events), with a neutral or aversive sound. During retrieval, we tested participants’ memory of temporal order memory and object-colour binding. We found opposite effects of emotion and event segmentation on episodic memory. While event segmentation enhanced object-context binding, emotion impaired it. On the contrary, event segmentation impaired temporal order memory, but emotion enhanced it. These findings increase our understanding of episodic memory organisation in laboratory settings, and potentially in real life with perceptual changes and emotion fluctuations constantly interacting.

Shin and DuBrow propose that a key principle driving event segmentation relates to causal analyses: specifically, that experiences that are attributed as having the same underlying cause are grouped together into an event. This offers an alternative to accounts of segmentation based on prediction error.

People tend to perceive ongoing continuous activity as series of discrete events. This partitioning of continuous activity may occur, in part, because events correspond to dynamic patterns that have recurred across different contexts. Recurring patterns may lead to reliable sequential dependencies in observers' experiences, which then can be used to guide perception. The current set of simulations investigated whether this statistical structure within events can be used 1) to develop stable internal representations that facilitate perception and 2) to learn when (...) to update such representations in a self-organizing manner. These simulations demonstrate that experience with recurring patterns enables a system to accurately predict upcoming stimuli within an event, to identify boundaries between such events based on transient increases in prediction error, and to use such boundaries to improve prediction about subsequent activities.

We describe a novel computational theory of how individuals segment perceptual information into representations of events. The theory is inspired by recent findings in the cognitive science and cognitive neuroscience of event segmentation. In line with recent theories, it holds that online event segmentation is automatic, and that event segmentation yields mental simulations of events. But it posits two novel principles as well: first, discrete episodic markers track perceptual and conceptual changes, and can be (...) retrieved to construct event models. Second, the process of retrieving and reconstructing those episodic markers is constrained and prioritized. We describe a computational implementation of the theory, as well as a robotic extension of the theory that demonstrates the processes of online event segmentation and event model construction. The theory is the first unified computational account of event segmentation and temporal inference. We conclude by demonstrating now neuroimaging data can constrain and inspire the construction of process-level theories of human reasoning. (shrink)

Whether non-human animals can have episodic memories remains the subject of extensive debate. A number of prominent memory researchers defend the view that animals do not have the same kind of episodic memory as humans do, whereas others argue that some animals have episodic-like memory—i.e., they can remember what, where and when an event happened. Defining what constitutes episodic memory has proven to be difficult. In this paper, I propose a dual systems account and provide evidence for a distinction (...) between event memory and episodic memory. Event memory is a perceptual system that evolved to support adaptive short-term goal processing, whereas episodic memory is based on narratives, which bind event memories into a retrievable whole that is temporally and causally organized around subject’s goals. I argue that carefully distinguishing event memory from episodic memory can help resolve the debate. (shrink)

Butz, Achimova, Bilkey, and Knott provide a topic overview and discuss whether the special issue contributions may imply that event‐predictive abilities constitute a root for conceptual human thought, because they enable complex, mutually beneficial, but also intricately competitive, social interactions and language communication.

Events are center stage in several fields of psychological research. There is a long tradition in the study of event perception, event recognition, event memory, event conceptualization and segmentation. There are studies devoted to the description of events in language and to their representation in the brain. There are also metapsychological studies aimed at assessing the nature of mental events or the grounding of intentional action. Outside psychology, the notion of an event plays a (...) prominent role in various areas of philosophy as well as in such diverse disciplines as linguistics, probability theory, artifical intelligence, physics, and�of course� history. This plethora of concerns and applications is indicative of the prima facie centrality of the notion of an event in our conceptual scheme, but it also gives rise to some important methodological questions. Can we identify a core notion that is preserved across disciplines? Does this notion, or some such notion, correspond to the pre-theoretical conception countenanced by common sense? Does it correspond to a genuine metaphysical category? (shrink)

Events—the experiences we think we are having and recall having had—are constructed; they are not what actually occurs. What occurs is ongoing dynamic, multidimensional, sensory flow, which is somehow transformed via psychological processes into structured, describable, memorable units of experience. But what is the nature of the redescription processes that fluently render dynamic sensory streams as event representations? How do such processes cope with the ubiquitous novelty and variability that characterize sensory experience? How are event‐rendering skills acquired and (...) how do event representations change with development? This review considers emerging answers to these questions, beginning with evidence that an implicit tendency to monitor predictability structure via statistical learning is key to event rendering. That is, one way that the experience of bounded events (e.g., actions within behavior, words within speech) arises is with the detection of “troughs” in sensory predictability. Interestingly, such troughs in predictability are often predictable; these regions of predictable‐unpredictability provide articulation points to demarcate one event from another in representations derived from the actual streaming information. In our information‐optimization account, a fluent event‐processor predicts such troughs and selectively attends to them—while suppressing attention to other regions—as sensory streams unfold. In this way, usage of attentional resources is optimized for efficient sampling of the most relevant, information‐rich portions of the unfolding flow of sensation. Such findings point to the development of event‐processing fluency—whether in action, language, or other domains—depending crucially on rapid and continual cognitive reorganization. As knowledge of predictability grows, attention is adaptively redeployed. Accordingly, event experiences undergo continuous alteration. (shrink)

Popular movies present chunk-like events that promote episodic, serial updating of viewers’ representations of the ongoing narrative. Event-indexing theory would suggest that the beginnings of new scenes trigger these updates, which in turn require more cognitive processing. Typically, a new movie event is signaled by an establishing shot, one providing more background information and a longer look than the average shot. Our analysis of 24 films reconfirms this. More important, we show that, when returning to a previously shown (...) location, the re-establishing shot reduces both context and duration while remaining greater than the average shot. In general, location shifts dominate character and time shifts in event segmentation of movies. In addition, over the last 70 years re-establishing shots have become more like the noninitial shots of a scene. Establishing shots have also approached noninitial shot scales, but not their durations. Such results suggest that film form is evolving, perhaps to suit more rapid encoding of narrative events.

In order to understand ongoing activity, observers segment it into meaningful temporal parts. Segmentation can be based on bottom‐up processing of distinctive sensory characteristics, such as movement features. Segmentation may also be affected by top‐down effects of knowledge structures, including information about actors' intentions. Three experiments investigated the role of movement features and intentions in perceptual event segmentation, using simple animations. In all conditions, movement features significantly predicted where participants segmented. This relationship was stronger when participants (...) identified larger units than when they identified smaller units, and stronger when the animations were generated randomly than when they were generated by goal‐directed human activity. This pattern suggests that bottom‐up processing played an important role in segmentation of these stimuli, but that this was modulated by top‐down influence of knowledge structures. To describe accurately how observers perceive ongoing activity, one must account for the effects of distinctive sensory characteristics, the effects of knowledge structures, and their interactions.

Events can be modeled through a geometric approach, representing event structures in terms of spaces and mappings between spaces. At least two spaces are needed to describe an event, an action space and a result space. In this article, we invoke general mathematical structures in order to develop this geometric perspective. We focus on three cognitive processes that are crucially involved in events: causal thinking, control of action and learning by generalization. These cognitive processes are supported by three (...) corresponding mathematical properties: monotonicity (that we relate to qualitative causal thinking and allows extrapolation); continuity (that plays a key role in our activities of action control); and convexity (that facilitates generalization and the categorization of events, and enables interpolation). We define how such properties constrain events representations and relate them to thinking about events. We discuss the relevance of the three constraints for event segmentation and explore the implications of such constraints for semantics. We conclude by a discussion that relates our approach to other accounts of events. (shrink)

Remembering when emotional experiences occurred can be adaptive, yet there is no consensus on how emotion influences temporal aspects of memory. Temporal memory, a type of associative memory, refers to the capacity to encode, store, and retrieve information about the sequence and timing of events. This Special Issue presents evidence on how emotion affects three aspects of temporal memory: temporal-order, temporal source, and event segmentation. The contributions suggest that emotion often increases temporal-order memory, a result that is harder (...) to reconcile with some dominant emotional memory theories, including the Object-Based Framework, the Dual Representation Account or other trade-off models, but may fit with Arousal-Biased Competition theory. The contributions also suggest that emotion can act as a boundary between events, although only under some experimental set-ups. Findings regarding its effect on temporal source memory were less clear. We discuss the diversity of findings in light of theories of emotional associative memory and methodological factors, such as the direction of the shift in emotional experience and discrepancies between temporal-order and temporal distance measures as indices of event boundaries. We provide a roadmap for future studies aimed at understanding how emotion shapes the fate of our memories as they unfold in time. (shrink)

When we read narrative texts such as novels and newspaper articles, we segment information presented in such texts into discrete events, with distinct boundaries between those events. But do our eyes reflect this event structure while reading? This study examines whether eye movements during the reading of discourse reveal how readers respond online to event structure. Participants read narrative passages as we monitored their eye movements. Several measures revealed that event structure predicted eye movements. In two experiments, (...) we found that both early and overall reading times were longer for event boundaries. We also found that regressive saccades were more likely to land on event boundaries, but that readers were less likely to regress out of an event boundary. Experiment 2 also demonstrated that tracking event structure carries a working memory load. Eye movements provide a rich set of online data to test the cognitive reality of event segmentation during reading. (shrink)

Research has shown that both adults and children organize familiar activity into discrete units with consistent boundaries, despite the dynamic, continuous nature of everyday experiences. However, less is known about how observers segment unfamiliar event sequences. In the current study, we took advantage of the novelty that is inherent in modern dance. Modern dance features natural human motion but does not contain canonical goals—therefore, observers cannot recruit prior goal‐related knowledge to segment it. Our main aims were to identify whether (...) observers segment modern dance into the steps intended by the dancers, and what types of cues contribute to segmentation under these circumstances. Experiment 1 used a classic event segmentation task and found that adults were able to consistently identify only a few of the dancers’ intended steps. Experiment 2 tested adults in an offline labeling task. Results showed that steps which could more easily be labeled offline in Experiment 2 were more likely to be segmented online in Experiment 1.

Pioneering molecular work on chelicerate visual system development in the horseshoe crabLimulus polyphemussurprised with the possibility that this process may not depend on the deeply conserved retinal determination function ofPax6transcription factors.

Following this phylotypic stage, chelicerate visual (...) system development differs fundamentally from other arthropods during the compartmentalization of the ocular segment in that eye and optic neuropil primordia originate independently from each other. Comparative analyses of this phase identified further gene regulatory homologies but also major differences, most notably the possibly compensatory replacement ofPax6byPax2in lateral eye specification.

A current issue in psycholinguistic research is whether the language difficulties exhibited by children with developmental language disorder [DLD, previously labeled specific language impairment ] are due to deficits in their abilities to pick up patterns in the sensory environment, an ability known as statistical learning, and the extent to which explicit learning mechanisms can be used to compensate for those deficits. Studies designed to test the compensatory role of explicit learning mechanisms in children with DLD are, however, scarce, and (...) the few conducted so far have led to inconsistent results. This work aimed to provide new insights into the role that explicit learning mechanisms might play on implicit learning deficits in children with DLD by resorting to a new approach. This approach involved not only the collection of event-related potentials, while preschool children with DLD [relative to typical language developmental controls] were exposed to a continuous auditory stream made of the repetition of three-syllable nonsense words but, importantly, the collection of ERPs when the same children performed analogous versions of the same auditory SL task first under incidental and afterward under intentional conditions. In each of these tasks, the level of predictability of the three-syllable nonsense words embedded in the speech streams was also manipulated to mimic natural languages closely. At the end of both tasks’ exposure phase, children performed a two-alternative forced-choice task from which behavioral evidence of SL was obtained. Results from the 2-AFC tasks failed to show reliable signs of SL in both groups of children. The ERPs data showed, however, significant modulations in the N100 and N400 components, taken as neural signatures of word segmentation in the brain, even though a detailed analysis of the neural responses revealed that only children from the TLD group seem to have taken advantage of the previous knowledge to enhance SL functioning. These results suggest that children with DLD showed deficits both in implicit and explicit learning mechanisms, casting doubts on the efficiency of the interventions relying on explicit instructions to help children with DLD to overcome their language difficulties.

Children's imitation of adults plays a prominent role in human cognitive development. However, few studies have investigated how children represent the complex structure of observed actions which underlies their imitation. We integrate theories of action segmentation, memory, and imitation to investigate whether children's event representation is organized according to veridical serial order or a higher level goal structure. Children were randomly assigned to learn novel event sequences either through interactive hands-on experience or via storybook. Results demonstrate that (...) children's representation of observed actions is organized according to higher level goals, even at the cost of representing the veridical temporal ordering of the sequence. We argue that prioritizing goal structure enhances event memory, and that this mental organization is a key mechanism of social-cognitive development in real-world, dynamic environments. It supports cultural learning and imitation in ecologically valid settings when social agents are multitasking and not demonstrating one isolated goal at a time. (shrink)

Studies on event-related potentials (ERP) in code-switching (CS) have concentrated on single-word insertions, usually nouns. However, CS ranges from inserting single words into the main language of discourse to alternating languages for larger segments of a discourse, and can occur at various syntactic positions and with various word classes. This ERP study examined native speakers of Russian who had learned German as a second language; they were asked to listen to sentences with CS from their second language, German, to (...) their first language, Russian. CS included either a whole prepositional phrase or only the lexical head noun of a prepositional phrase. CS at nouns resulted in a late positive complex (LPC), whereas CS at prepositions resulted in a broad early negativity, which was followed by an anterior negativity with a posterior positivity. Only in the last time window (800–1000 ms) did CS at prepositions result in a broad positivity similar to CS at nouns. The differences between both types of CS indicate that they relate to different psycholinguistic processes. (shrink)

For a robot to be capable of development it must be able to explore its environment and learn from its experiences. It must find opportunities to experience the unfamiliar in ways that reveal properties valid beyond the immediate context. In this paper, we develop a novel method for using the rhythm of everyday actions as a basis for identifying the characteristic appearance and sounds associated with objects, people, and the robot itself. Our approach is to identify and segment groups of (...) signals in individual modalities based on their rhythmic variation, then to identify and bind causally-related groups of signals across different modalities. By including proprioception as a modality, this cross-modal binding method applies to the robot itself, and we report a series of experiments in which the robot learns about the characteristics of its own body.

This paper proposes how various disciplinary theories of cognition may be combined into a unifying, sub-symbolic, computational theory of cognition. The following theories are considered for integration: psychological theories, including the theory of event coding, event segmentation theory, the theory of anticipatory behavioral control, and concept development; artificial intelligence and machine learning theories, including reinforcement learning and generative artificial neural networks; and theories from theoretical and computational neuroscience, including predictive coding and free energy-based inference. In the light (...) of such a potential unification, it is discussed how abstract cognitive, conceptualized knowledge and understanding may be learned from actively gathered sensorimotor experiences. The unification rests on the free energy-based inference principle, which essentially implies that the brain builds a predictive, generative model of its environment. Neural activity-oriented inference causes the continuous adaptation of the currently active predictive encodings. Neural structure-oriented inference causes the longer term adaptation of the developing generative model as a whole. Finally, active inference strives for maintaining internal homeostasis, causing goal-directed motor behavior. To learn abstract, hierarchical encodings, however, it is proposed that free energy-based inference needs to be enhanced with structural priors, which bias cognitive development towards the formation of particular, behaviorally suitable encoding structures. As a result, it is hypothesized how abstract concepts can develop from, and thus how they are structured by and grounded in, sensorimotor experiences. Moreover, it is sketched-out how symbol-like thought can be generated by a temporarily active set of predictive encodings, which constitute a distributed neural attractor in the form of an interactive free-energy minimum. The activated, interactive network attractor essentially characterizes the semantics of a concept or a concept composition, such as an actual or imagined situation in our environment. Temporal successions of attractors then encode unfolding semantics, which may be generated by a behavioral or mental interaction with an actual or imagined situation in our environment. Implications, further predictions, possible verification and falsifications, as well as potential enhancements into a fully spelled-out unified theory of cognition are discussed at the end of the paper.

This chapter explores to what extent some core ideas of predictive processing can be applied to the phenomenology of time consciousness. The focus is on the experienced continuity of consciously perceived, temporally extended phenomena (such as enduring processes and successions of events). The main claim is that the hierarchy of representations posited by hierarchical predictive processing models can contribute to a deepened understanding of the continuity of consciousness. Computationally, such models show that sequences of events can be represented as states (...) of a hierarchy of dynamical systems. Phenomenologically, they suggest a more fine-grained analysis of the perceptual contents of the specious present, in terms of a hierarchy of temporal wholes. Visual perception of static scenes not only contains perceived objects and regions but also spatial gist; similarly, auditory perception of temporal sequences, such as melodies, involves not only perceiving individual notes but also slightly more abstract features (temporal gist), which have longer temporal durations (e.g., emotional character or rhythm). Further investigations into these elusive contents of conscious perception may be facilitated by findings regarding its neural underpinnings. Predictive processing models suggest that sensorimotor areas may influence these contents. (shrink)

Temporal stability and change in neutral contexts can transform continuous experiences into distinct and memorable events. However, less is known about how shifting emotional states influence these memory processes, despite ample evidence that emotion impacts non-temporal aspects of memory. Here, we examined if emotional stimuli influence temporal memory for recent event sequences. Participants encoded lists of neutral images while listening to auditory tones. At regular intervals within each list, participants heard emotional positive, negative, or neutral sounds, which served as (...) “emotional event boundaries” that divided each sequence into discrete events. Temporal order memory was tested for neutral item pairs that either spanned an emotional sound or were encountered within the same auditory event. Encountering a highly arousing event boundary led to faster response times for items encoded within the next event. Critically, we found that highly arousing sounds had different effects on binding ongoing versus ensuing sequential representations in memory. Specifically, highly arousing sounds were significantly more likely to enhance temporal order memory for ensuing information compared to information that spanned those boundaries, especially for boundaries with negative valence. These findings suggest that within aversive emotional contexts, fluctuations in arousal help shape the temporal organisation of events in memory. (shrink)

This paper considers the cognitive penetrability of our experiences of the durations of everyday events. I defend an account of subjective duration based in contemporary psychological and neurobiological research. I show its philosophical adequacy by demonstrating its utility in explain-ing the phenomenology of duration experiences. I then consider whether cognitive penetrability is a problem for these experiences. I argue that, to the contrary, the problem presupposes a relationship between perception and belief that duration perceptions and beliefs do not exhibit. In-stead, (...) the assignment of epistemic features to particular processing stages appears to answer to pragmatic needs, not psychological facts. (shrink)

It is difficult to create spoken forms that can be understood on the spot. But the manual modality, in large part because of its iconic potential, allows us to construct forms that are immediately understood, thus requiring essentially no time to develop. This paper contrasts manual forms for actions produced over three time spans—by silent gesturers who are asked to invent gestures on the spot; by homesigners who have created gesture systems over their life spans; and by signers who have (...) learned a conventional sign language from other signers—and finds that properties of the predicate differ across these time spans. Silent gesturers use location to establish co-reference in the way established sign languages do, but they show little evidence of the segmentation sign languages display in motion forms for manner and path, and little evidence of the finger complexity sign languages display in handshapes in predicates representing events. Homesigners, in contrast, not only use location to establish co-reference but also display segmentation in their motion forms for manner and path and finger complexity in their object handshapes, although they have not yet decreased finger complexity to the levels found in sign languages in their handling handshapes. The manual modality thus allows us to watch language as it grows, offering insight into factors that may have shaped and may continue to shape human language. (shrink)

A language is a system of signs used for communication, and linguists are tasked with, among other things, uncovering the syntax and semantics of such systems. In this paper I explore to what extent pictures fit this characterization of a language and hence would fall within the domain of linguistics. I conclude that at the very least there are well-defined systems of depiction for which we can give a precise semantics, in a familiar possible worlds framework, although pictorial propositions are (...) not derived via the linguistically familiar lexicon and recursive composition rules, but via geometric projection. I then show how sequences of pictures, like sequences of utterances, can be used to form coherent discourses. I explore in some detail extensions of the formal discourse semantics of Segmented Discourse Representation Theory to deal with comics, i.e. storytelling through picture sequences. I focus specifically on the representation of events in comics, and the integration of both symbolic and iconic elements. (shrink)

Donald Davidson claims that, by studying the most general aspects of natural language, we will also be studying the most general aspects of reality.In particular, this means that, through the application of a systematic truththeory to natural language, we will be able to reveal its basic structure, its true logical form. Once this logical form has been spelled out, we will be able to determine the finite stock of important constituents of which sentences are built, and also the specific roles (...) these “atoms” play in the relevant structure. Since the structure of language can be said to “mirror” the structure of reality, this also means that we can now say something about the basic constituents of the world. We will be able to tell which kinds of entities exist and which do not. If, by spelling out the logical form, we find that there is a sentence (or several sentences) committing us to the existence of a certain (kind of) object (i.e. a sentence where an object (of this kind)serves as the value of a quantified variable) and, if we know the sentence to be true, then we have good reason to suppose that there is an object (of that kind) rather than not. This will hold given that there is no other way of spelling out the logical form of the sentence in question that is compatible with the nonexistence of that (kind of) object. So what exists is what, according to the (complete) theory, functions as values of the quantified variables, once thelogical form, the basic structure, of all the sentences of the language has been spelled out. Davidson has claimed that what all this quantificational structure will demand from ontology is the existence of objects and particular events. This should be taken somewhat at faith. In order to reach valid conclusions concerning the logical form of natural language, Davidson would have to examine allof its true sentences, and state allof their truth conditions, which he has not done. For practical reasons he has only been able to look at small segments of language, to consider how they normally function, to attempt to exhibit their logical structure by looking at entailment-relations, etc., and it is from this that he has drawn his ontological conclusions. In this paper, I concentrate on some of the likely consequences of the adoption of this method of reaching ontological conclusions. In particular, I will try to show that Davidson’s own way of arguing for the existence of events can be applied to cases where he seemingly would have to commit himself to the existence of properties too. To demonstrate this, I begin by considering whether the fact that Davidson spells out the logical form of natural language in first-order logic raises a serious objection to my claim or not. I then proceed by making a case for properties using an argument based on what Davidson has to say about the existence of events. What I will try to show is that, if Davidson is to be true to his general method of reaching conclusions regarding existence, which he claims to be, then he must go where this method leads him. This means that he has to keep his mind open as to the kinds of entities he should or should not allow. Finally, assuming that I have shown properties to be one of the different kinds of entities that a Davidsonian would have to allow, I conclude the paper by indicating what the consequence(s) of this may be.

The human experience is shaped by information from different perceptual channels, but it is still debated whether and how differential experience influences language use. To address this, we compared congenitally blind, blindfolded, and sighted people's descriptions of the same motion events experienced auditorily by all participants (i.e., via sound alone) and conveyed in speech and gesture. Comparison of blind and sighted participants to blindfolded participants helped us disentangle the effects of a lifetime experience of being blind versus the task-specific effects (...) of experiencing a motion event by sound alone. Compared to sighted people, blind people's speech focused more on path and less on manner of motion, and encoded paths in a more segmented fashion using more landmarks and path verbs. Gestures followed the speech, such that blind people pointed to landmarks more and depicted manner less than sighted people. This suggests that visual experience affects how people express spatial events in the multimodal language and that blindness may enhance sensitivity to paths of motion due to changes in event construal. These findings have implications for the claims that language processes are deeply rooted in our sensory experiences. (shrink)

It has been suggested that damage to anterior regions of the left hemisphere results in a dissociation in the perception and lexical activation of past-tense forms. Specifically, in a lexical-decision task in which past-tense primes immediately precede present-tense targets, such patients demonstrate significant priming for irregular verbs (spoke–speak), but, unlike control participants, fail to do so for regular verbs (looked–look). Here, this behavioral dissociation was first confirmed in a group of eleven patients with damage to the pars opercularis (BA 44) (...) and pars triangularis (BA 45) of the left inferior frontal gyrus (i.e., Broca's area). Two conditions containing word-onset orthographic–phonological overlap (bead–bee, barge–bar) demonstrated that the disrupted regular-verb priming was accompanied by, and covaried with, disrupted ortho-phonological priming, regardless of whether prime stimuli contained the regular inflectional rhyme pattern. Further, the dissociation between impaired regular-verb and preserved irregular-verb priming was shown to be continuous rather than categorical; priming for weak-irregular verbs (spent–spend) was intermediate in size between that of regular verbs and strong verbs. Such continuous dissociations grounded in ortho-phonological relationships between present- and past-tense forms are predicted by single-system, connectionist approaches to inflectional morphology and not predicted by current dual-system, rule-based models. Event-related potential data demonstrated that N400 priming effects were intact for both regular and irregular verbs, suggesting that the absence of significant regular-verb priming in the response time data did not result from a disruption of lexical access, and may have stemmed instead from post-lexical events such as covert articulation, segmentation strategies, and/or cognitive control.

It is by now a commonplace that the classification of sciences into nomological and ideographical, which originated with Windelband, is neither exhaustive nor exclusive. Rather, there are sciences in which nomothetical activities are prevalent and there are sciences in which ideographical efforts dominate. A third kind of enterprise is widespread throughout most, if not all, sciences: typological undertakings. In some sciences these are the most important and dominant projects. Linguistics tries to establish types of expressions: phonemes, morphemes, syntactical categories. History (...) of art endeavors to set up various styles, i. e., types of art. General history attempts at well founding of such notions as revolution, reaction, buonapartism, findesieclism. When a historian declares that a revolution starts when a housewife cannot buy a chicken on the market, he divides the stream of events into periods according to a criterion that seems to him important, establishes similarities between different periods, and classifies them into types. Such typological activities are common not only in social sciences and humanities but also in physics which speaks about explosions, collisions, changes from a positive to a negative acceleration. A mathematician often enters into a typological venture, e.g., when he analyzes a function as increasing in an interval or describes it as concave upward in another interval. Typology may be conceived as containing the theory of classification. But there are typological problems that are not included in the theory of classification. A classification is performed on a class when its subclasses are defined. Typology, as suggested by the examples, may take a single object and try to conceive it as a summation of its fragments. To find a segmentation suitable from some point of view is not a classification. Rather, classification presupposes segmentation. (shrink)

Type 1: This process occurs for half of the population. For this segment of the population, there is 10% chance of developing the disease. There is a test for the disease such that 90% of the people who have the disease in this case will test positive (event E), while the false positive rate is 10%, which means that there is a 10% chance of testing positive for the disease when they do not have the disease.

In lieu of an abstract, here is a brief excerpt of the content:American Journal of Philology 122.3 (2001) 415-428 [Access article in PDF] Brief Mention Tantalus Helene P. Foley John Barton's Tantalus bills itself repeatedly as "leftovers from the epic cycle." 1 Although his cycle of plays--nine in the stage performance and ten, with prologue and epilogue, in the published script--also remakes some late Euripidean plays, the spirit of the piece as a whole is far more reminiscent of what we (...) know of cyclic epic than tragedy or even the Iliad and Odyssey themselves, which, as Aristotle's Poetics points out, are plotted in a distinctively tragic manner with a single unifying action. Sir Peter Hall and Edward Hall's performance version, which premiered in fall 2000 at the Denver Center for the Performing Arts and then traveled to England, is conveniently divided into hour-long segments with intermissions and meal breaks that cater to the sensibilities and attention spans of viewers accustomed to televised series like Masterpiece Theater. Any attempt to recapture the tight plotting, intensity, complexity, and tension of tragedy would inevitably fail in a performance of this scale. Instead, the viewer is drawn into a long and varied narrative replete with surprising shifts in tone, ranging from ironic to lyrical, from painful to comic; episodes drawn from obscure mythological sources or, occasionally, invented, take center stage, while episodes familiar from Homer and tragedy are deliberately deleted. Viewers can follow characters and children of characters over the series of plays and see the traits of siblings and parents emerge with variation in close relatives--an effect enhanced onstage by the fact that these relatives are often played by the same actors. Like cyclic epic, Tantalus fills in the gaps left by Homer [End Page 427] in the Trojan saga and aspires to tantalize its viewers with the possibi415lity of multiple and unstable versions of mythic truth. In addition, although the play repeatedly evokes the image of the rock of Tantalus poised to crash with finality on everyone's head, it largely espouses a cyclic and inconclusive view of history, in which events and human errors relentlessly repeat themselves without acquiring accessible meaning. "Until the great rock falls / What has happened already / Will happen again: / That is god-law, Agamemnon, / As it's man-law on earth. / Epikou Kuklou leipsana" (362).Playwright Barton and the directors fell out during the rehearsal process; the Irish playwright Colin Teevan shortened, revised, and in some critical ways transformed and trivialized Barton's original script. The stage version retains Barton's concern with the futility of war and human action but radically revises the major point of the original. Barton's script above all engages its audience in the myth-making process and the elusive truth of stories: "Who is to Blame? What is the Truth? Could it be Otherwise?" His script opens with a group of twelve "girls" (Barton's term) sleeping on barren ground. Nine (in the performance, ten) of the girls become a chorus, and the remaining ones (the script says four, though the total of twelve demands three, so there may be an error in the script here) play various female parts throughout the cycle. The group has missed the (real or mythical) boat and begins to tell one another conflicting myths about the origin of the world. The chorus, which claims to know all the traditional Greek myths, wants to know which version is true. It debates whether to drink from the nearby oracular streams of Trophonius. (One stream makes one forget the present moment; the other makes one remember even things one does not consciously know.)A poet (and tutor to Dionysus) enters with a wine bag. The skeptical chorus, which at first prefers its own stories and one truth, is lured into testing out the poet's bag of masks and engaging with multiple conflicting stories. "If you want to know the future / You must go into the past" (511). The poet and the four women don new roles and reenact story fragments for the increasingly engaged chorus. The chorus women toss stones over their shoulders in imitation of the Greek creation... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Temporal Registers in the Realist NovelIlya BernsteinIThere are two ways of thinking about time: in terms of sequences of events, and in terms of time-scales. In the first case, each event is conceived of as having a "before" and an "after": it is categorized as part of a sequence and distinguished from other events by its position in that sequence. In the second case, there is no "before" (...) and "after": events are conceived of as occupying different time-scales and distinguished from one another by being associated with durations of greater or lesser magnitude.1 Thus, the same situation may be categorized alternatively as an unfolding succession of events (event 1, event 2, event 3...) or as a progression of overlapping events on expanding time-scales (the second-event, the minute-event, the hour-event...). In what follows, I will argue that this distinction can shed light on narrative structure—as well as musical form—and that it has particularly interesting implications for literary realism.It may be claimed that this distinction between two ways of approaching time has been an explicit theme in the arts over the course of their history. Different musical forms, for instance, may be seen as being oriented toward one paradigm or the other. Thus, melody aesthetically suggests a sequential conception of time. Melodic forms are supposed to take listeners on a journey from point A to point B, by way of a succession of points in between. By contrast, a form such as the fugue addresses itself to discovering different degrees of density and intensity within the [End Page 173] same event, as it were. It adds layer upon layer, aesthetically dilating the event without moving away from it. The ideology of melody, we might say, thus leans toward a conception of time as a sequence, while the ideology of the fugue suggests a scaling notion of time.Echoes of the distinction between these two aesthetic alternatives may also be found in literature, as embodied in different approaches to narrative. Narrative, conceived of as a succession of episodes, suggests a sequential conception of time, oriented around a "before" and an "after." Yet within these parameters, a spectrum of tendencies may be identified. In some literary forms, the succession of episodes is organized to suggest the idea of a passage from one event to the next (Shakespearean drama, the realist novel), as the notions of "before" and "after" are projected onto ideas of past and future. In others, the succession of episodes represents the layer-by-layer assembly of some larger imaginative or conceptual construct (as is true, in different ways, of such texts as Plato's dialogues, the Divine Comedy, and any number of religious, philosophical, or allegorical narratives): "before" and "after" are interpreted not so much in terms of a past and a future, as in terms of premises and conclusions.Within this spectrum, the novel—and perhaps the realist novel in particular—would appear to be the literary form par excellence that embodies a sequential conception of time. It thematizes and dramatizes time's passage—the unknowability of the future and the irretrievability of the past—more exhaustively than any other narrative genre. Yet as I hope to show below, while the explicit themes of literary realism treat fictional events as a sequence (event 1, event 2, event 3...), its implicit organization is grounded in time-scales and directs readers' attention to differentiations among events taking place at different temporal registers (the sentence-event, the chapter-event, the novel-event...).III would like to begin exploring the theoretical distinction laid out above by going back to music and focusing on an empirical observation that has been made about a variety of musical forms. It has been pointed out that when people listen to a piece of music, they retain in their memory, at greater or lesser degrees of awareness, a certain segment of what they have just heard; this memory serves as a background for their perception of incoming sounds and as a frame of reference for their experience of them. Consequently, musical forms may be characterized, [End Page 174] compared, and distinguished from one another based... (shrink)

Goal of this article is to study the system application directions of marketing tools and technologies to improve the competitiveness of the region and regional markets in the changing conditions of the environment. It is noted that the theory and practice of marketing in the modern territorial administration considers it as a key factor of competitiveness, which will help to keep existing residents and attract expensive, educated, skilled workforceand form comfortable conditions for the operation of existing businesses and develop programs (...) of attractiveness for investors and new entrepreneurs, to develop a unique tourism product focused on the re-visiting etc. It was considered the role of regional marketing definitions of national and foreign scientists. The attention is focused to the fact that despite the growth of attention of theorists and practitioners to territorial management technologies and marketing tools, many questions remain in terms of adapting to the needs of different territorial levels. The main problems associated with the direct transfer of technology of the corporate sector in management system and life activity of regions and cities. Stated that competitiveness as the object marketing impact should be considered within the classical concept of territorial marketing, according to which the bodies of local authorities should seek to identify current and future needs of target segments and play them in goods and services area better than do competitors. The classical concept, along with other modern concepts of territorial marketing gives to marketing a kind of integrator partnership of territorial authorities and target audiences. Were described the main subjects marketing in the region, discussed their role in enhancing the competitiveness of the regional markets systems on condition of the realization of their own interests and considered. It is noted that the main task of marketing should be increasing the attractiveness of its territory - complex of resources conditions, relationships, objects that allow in the market conditions to reorient themselves to the flow of resources, which will compete with other regions. Marketing territories allows to clearly understand that successful economic and social development should be to re-evaluate the area and conditions for the operation and development of the territory. It was established that today is activated the use of marketing approach in the local administration, but there is no systematic use of all marketing tools when forming strategies of Ukrainian cities and regions the use of limited marketing application of communication tools and event technologies and remain out of sight other important elements of the marketing mix. Specified directions for using the elements of the marketing mix in the process of ensuring the competitiveness of the region and the transformation of the system of regional markets. Integrated use of elements of the complex of territorial marketing, its successful "mixing", harmonization of marketing strategies and policies, can form a set of practical tools of adaptation the region to the market situation in the region to ensure competitiveness and create conditions for the implementation of strategic development programs. It was concluded that regional marketing system of regional markets makes it possible to form the best competitive advantages for customers compared with other areas, promotes the efficient use of resources to improve the competitiveness and image, helping to attract economic agents increasing the attractiveness and competitiveness of the region aimed at sustainable development of the region, and creating a long term and mutually beneficial relationships with internal and external partners. Client-orientation of marketing approach to the management of the region and to transform the system of regional markets allows you to create unique properties of the region as a place of residence, visiting, business investment and promote it successfully in domestic and foreign markets.

Sensory dysfunction has been shown to be a part of the pathophysiology of schizophrenia. Nowadays we have an objective, non-invasive tool with which to measure neural manifestations of sensory dysfunction. Defined as time-locked changes to external stimuli in the EEG, event-related potentials (ERPs) provide an objective index of information processing in the human brain. Importantly, ERPs may be analyzed through a variety of approaches such as conventional ERP analysis, analysis in the time-frequency domain, microstate segmentation and topographical analysis, (...) as well as source localisation analysis. Each of the methods gives distinct information; they also supplement each other. Here, an attempt is made to verify the validity of combining different approaches to study sensory dysfunction in neuropsychiatric disorders. For example, the data from a schizophrenic patient and an age- and sex-matched healthy subject generate a picture of the events which emerges after visual, proprioceptive and simultaneous presentation of stimuli in both modalities. This approach, though time-consuming, allows the visualisation of changes appearing in the malfunctioning brain as compared to the healthy brain. These methods could ultimately lead to a better establishment of one or more endophenotypes for the schizophrenic disorders. They might also serve as a way to track changes in response to various medications and therapies. (shrink)

This paper and its predecessor () are about the question: 'Are the events in the entire universe encoded in and predictable from any of its parts?' To approach a positive answer in classical physics, the following result is proved and commented on: in Newton's theory of gravitation, the entire trajectory of a particle can be predicted given any segment of it, regardless of how the other particles are moving-provided that there is only a finite number of particles and that their (...) speeds remain bounded. (It is this condition, together with a set of parameters characterising the motion of the other particles, which enables us to estimate the effect of the other particles on the trajectory of the given particle.) The extension of this result to other theories, in particular to special relativity, is discussed. (shrink)
