  4. Resting state glutamate predicts elevated pre-stimulus alpha during self-relatedness: A combined EEG-MRS study on 'rest-self' overlap.Yu Bai, Timothy Lane, Georg Northoff & et al - 2015 - Social Neuroscience:DOI:10.1080/17470919.2015.107258.
    Recent studies have demonstrated neural overlap between resting state activity and self-referential processing. This “rest-self” overlap occurs especially in anterior cortical midline structures like the perigenual anterior cingulate cortex (PACC). However, the exact neurotemporal and biochemical mechanisms remain to be identified. Therefore, we conducted a combined electroencephalography (EEG)-magnetic resonance spectroscopy (MRS) study. EEG focused on pre-stimulus (e.g., prior to stimulus presentation or perception) power changes to assess the degree to which those changes can predict subjects’ perception (and judgment) (...)

    The combination of target motion and dynamic changes in context greatly enhance visual size illusions.Ryan E. B. Mruczek, Matthew Fanelli, Sean Kelly & Gideon P. Caplovitz - 2022 - Frontiers in Human Neuroscience 16:959367.
    Perceived size is a function of viewing distance, retinal images size, and various contextual cues such as linear perspective and the size and location of neighboring objects. Recently, we demonstrated that illusion magnitudes of classic visual size illusions may be greatly enhanced or reduced by adding dynamic elements. Specifically, a dynamic version of the Ebbinghaus illusion (classically considered a “size contrast” illusion) led to a greatly enhanced illusory effect, whereas a dynamic version of the Corridor illusion (a “size constancy” illusion) (...)

    Understanding the Impact of the Psychological Cognitive Process on Student Learning Satisfaction: Combination of the Social Cognitive Career Theory and SOR Model.Guihua Zhang, Xiaoyao Yue, Yan Ye & Michael Yao-Ping Peng - 2021 - Frontiers in Psychology 12.
    In higher education, student learning satisfaction is a significant predictor of learning that indicates the commitment students have to their learning and future academic achievement. The study combines the social cognitive career theory and the stimulus-organism-response model to explore the psychological cognition and attitudes derived from students during their learning, discusses the pattern of student learning satisfaction enhancement from the aspect of process, and further understands the relationships among social support systems, interaction relationships, self-efficacy, generic skills, and learning satisfaction.

    Combining Gamma With Alpha and Beta Power Modulation for Enhanced Cortical Mapping in Patients With Focal Epilepsy.Mario E. Archila-Meléndez, Giancarlo Valente, Erik D. Gommer, João M. Correia, Sanne ten Oever, Judith C. Peters, Joel Reithler, Marc P. H. Hendriks, William Cornejo Ochoa, Olaf E. M. G. Schijns, Jim T. A. Dings, Danny M. W. Hilkman, Rob P. W. Rouhl, Bernadette M. Jansma, Vivianne H. J. M. van Kranen-Mastenbroek & Mark J. Roberts - 2020 - Frontiers in Human Neuroscience 14.
    About one third of patients with epilepsy have seizures refractory to the medical treatment. Electrical stimulation mapping is the gold standard for the identification of “eloquent” areas prior to resection of epileptogenic tissue. However, it is time-consuming and may cause undesired side effects. Broadband gamma activity recorded with extraoperative electrocorticography during cognitive tasks may be an alternative to ESM but until now has not proven of definitive clinical value. Considering their role in cognition, the alpha and beta bands could further (...)

  8. The reward and punishment responsivity and motivation questionnaire (RPRM-Q): A stimulus-independent self-report measure of reward and punishment sensitivity that differentiates between responsivity and motivation.Nienke C. Jonker, Marieke E. Timmerman & Peter J. de Jong - 2022 - Frontiers in Psychology 13.
    Reward and punishment sensitivity seem important traits in understanding behavior in general and psychopathology in particular. Though the definitions used for reward and punishment sensitivity differentiate between responsivity and motivation, the measures thus far used to assess these constructs do not. Further, specificity of the type of reward and punishment in questionnaires might result in measurement bias especially when examining the relationship with psychopathology. Therefore, we developed a stimulus-independent multidimensional questionnaire of reward and punishment sensitivity that differentiates between responsivity (...)

    Frontal and occipital-parietal alpha oscillations distinguish between stimulus conflict and response conflict.Dandan Tang, Li Hu, Yi Lei, Hong Li & Antao Chen - 2015 - Frontiers in Human Neuroscience 9:119493.
    Conflicts between target and distraction can occur at the level of both stimulus and response processing. However, the neural oscillations underlying occurrence of the interference in different levels have not been understood well. Here, we reveal such a neural oscillation modulation by combining a 4:2 mapping design (two targets are mapped into one response key) with a practice paradigm (pretest, practice, and posttest) when healthy human participants were performing a novel color-word flanker task. Response time (RT) results revealed constant (...)

    Regulating Agents, Functional Interactions, and Stimulus-Reaction-Schemes: The Concept of “Organism” in the Organic System Theories of Stahl, Bordeu, and Barthez.Tobias Cheung - 2008 - Science in Context 21 (4):495-519.
    ArgumentIn this essay, I sketch a problem-based framework within which I locate the concept of “organism” in the system theories of Georg Ernst Stahl, Théophile Bordeu, and Paul-Joseph Barthez. Around 1700, Stahl coins the word “organism” for a certain concept of order. For him, the concept explains the form of order of living bodies that is categorically different from the order of other bodies or composites. At the end of the century, the “organism” as a specific form of order becomes (...)

    Oxiforms: Unique cysteine residue‐ and chemotype‐specified chemical combinations can produce functionally‐distinct proteoforms.James N. Cobley - 2023 - Bioessays 45 (7):2200248.
    A single protein molecule with one or more cysteine residues can occupy a plurality of unique residue and oxidation‐chemotype specified proteoforms that I term oxiforms. In binary reduced or oxidised terms, one molecule with three cysteines will adopt one of eight unique oxiforms. Residue‐defined sulfur chemistry endows specific oxiforms with distinct functionally‐relevant biophysical properties (e.g., steric effects). Their emergent complexity means a functionally‐relevant effect may only manifest when multiple cysteines are oxidised. Like how mixing colours makes new shades, combining discrete (...)

    Eye Gaze and Aging: Selective and Combined Effects of Working Memory and Inhibitory Control.Trevor J. Crawford, Eleanor S. Smith & Donna M. Berry - 2017 - Frontiers in Human Neuroscience 11:298724.
    Eye-tracking is increasingly studied as a cognitive and biological marker for the early signs of neuropsychological and psychiatric disorders. However, in order to make further progress, a more comprehensive understanding of the age-related effects on eye-tracking is essential. The antisaccade task requires participants to make saccadic eye movements away from a prepotent stimulus. Speculation on the cause of the observed age-related differences in the antisaccade task largely centers around two sources of cognitive dysfunction: inhibitory control (IC) and working memory (...)

    Feature-Based Attentional Weighting and Re-weighting in the Absence of Visual Awareness.Lasse Güldener, Antonia Jüllig, David Soto & Stefan Pollmann - 2021 - Frontiers in Human Neuroscience 15:610347.
    Visual attention evolved as an adaptive mechanism allowing us to cope with a rapidly changing environment. It enables the facilitated processing of relevant information, often automatically and governed by implicit motives. However, despite recent advances in understanding the relationship between consciousness and visual attention, the functional scope of unconscious attentional control is still under debate. Here, we present a novel masking paradigm in which volunteers were to distinguish between varying orientations of a briefly presented, masked grating stimulus. Combining signal (...)

    Two experiments examined how affective values from visual and auditory modalities are integrated. Experiment 1 paired music and videos drawn from three levels of valence while holding arousal constant. Experiment 2 included a parallel combination of three levels of arousal while holding valence constant. In each experiment, participants rated their affective states after unimodal and multimodal presentations. Experiment 1 revealed a congruency effect in which stimulus combinations of the same extreme valence resulted in more extreme state ratings than (...)

    The Effects of Computer-Based and Motor-Imagery Training on Scoring Ability in Lacrosse.Takahiro Hirao & Hiroaki Masaki - 2020 - Frontiers in Psychology 11:529374.
    Previous studies have confirmed that the temporal attentional control created by the repetition of stimulus-response compatibility (SRC) tasks was transferred to shooting skills in lacrosse players. In the current study, we investigated whether combining motor imagery training with SRC tasks could enhance the scoring ability of lacrosse players. We grouped 33 male lacrosse players into three groups: an SRC task and motor imagery group (referred as to SRC+Image), an SRC task group, and a control group. Players in the first (...)

    Finding ERP-signatures of target awareness: Puzzle persists because of experimental co-variation of the objective and subjective variables☆.Talis Bachmann - 2009 - Consciousness and Cognition 18 (3):804-808.
    Using masking techniques combined with electrophysiological recordings is a promising way to study neural correlates of visual awareness, as shown in recent studies. Here I comment on the following puzzling aspects typical for this endeavour that have made obstacles for a potentially even more impressive progress. First, the continuing practice of confounds between objective stimulus variables and subjective dependent measures. Second, complexity of timing the emergence of subjective conscious percept which is partly due to complex interactivity between target and (...)

To describe and explain the unity of consciousness, detailed phenomenological descriptions of binding at the phenomenal (...)

    Where are we to look for the unique hues? Out in the world? In the eye? In more central processing? 1. There are difficulties looking for the structure of the unique hues in simple combinations of cone-response functions like ( L − M ) and ( S − ( L + M )): such functions may fit pretty well the early physiological processing, but they don’t correspond to the structure of unique hues. It may seem more promising to look (...)

  22. Expanding the vector model for dispositionalist approaches to causation.Joseph A. Baltimore - 2019 - Synthese 196 (12):5083-5098.
    Neuron diagrams are heavily employed in academic discussions of causation. Stephen Mumford and Rani Lill Anjum, however, offer an alternative approach employing vector diagrams, which this paper attempts to develop further. I identify three ways in which dispositionalists have taken the activities of powers to be related: stimulation, mutual manifestation, and contribution combination. While Mumford and Anjum do provide resources for representing contribution combination, which might be sufficient for their particular brand of dispositionalism, I argue that those resources are not (...)

  23. Infants' discrimination of number vs. continuous extent.Elizabeth Spelke - manuscript
    Seven studies explored the empirical basis for claims that infants represent cardinal values of small sets of objects. Many studies investigating numerical ability did not properly control for continuous stimulus properties such as surface area, volume, contour length, or dimensions that correlate with these properties. Experiment 1 extended the standard habituation/dishabituation paradigm to a 1 vs 2 comparison with three-dimensional objects and confirmed that when number and total front surface area are confounded, infants discriminate the arrays. Experiment 2 revealed (...)

    A solution to the tag-assignment problem for neural networks.Gary W. Strong & Bruce A. Whitehead - 1989 - Behavioral and Brain Sciences 12 (3):381-397.
    Purely parallel neural networks can model object recognition in brief displays – the same conditions under which illusory conjunctions (the incorrect combination of features into perceived objects in a stimulus array) have been demonstrated empirically (Treisman 1986; Treisman & Gelade 1980). Correcting errors of illusory conjunction is the “tag-assignment” problem for a purely parallel processor: the problem of assigning a spatial tag to nonspatial features, feature combinations, and objects. This problem must be solved to model human object recognition (...)

    We outline the rationale and preliminary results of using the State Context Property (SCOP) formalism, originally developed as a generalization of quantum mechanics, to describe the contextual manner in which concepts are evoked, used, and combined to generate meaning. The quantum formalism was developed to cope with problems arising in the description of (1) the measurement process, and (2) the generation of new states with new properties when particles become entangled. Similar problems arising with concepts motivated the formal treatment introduced (...)

    Visual Search in 3D: Effects of Monoscopic and Stereoscopic Cues to Depth on the Validity of Feature Integration Theory and Perceptual Load Theory.Ciara M. Greene, John Broughan, Anthony Hanlon, Seán Keane, Sophia Hanrahan, Stephen Kerr & Brendan Rooney - 2021 - Frontiers in Psychology 12.
    Previous research has successfully used feature integration theory to operationalise the predictions of Perceptual Load Theory, while simultaneously testing the predictions of both models. Building on this work, we test the extent to which these models hold up in a 3D world. In two experiments, participants responded to a target stimulus within an array of shapes whose apparent depth was manipulated using a combination of monoscopic and stereoscopic cues. The search task was designed to test the predictions of feature (...)

    An ERP study on L2 syntax processing: When do learners fail?Nienke Meulman, Laurie A. Stowe, Simone A. Sprenger, Moniek Bresser & Monika S. Schmid - 2014 - Frontiers in Psychology 5:100571.
    Event-related brain potentials (ERPs) can reveal online processing differences between native speakers and second language (L2) learners during language comprehension. Using the P600 as a measure of native-likeness, we investigated processing of grammatical gender agreement in highly proficient immersed Romance L2 learners of Dutch. We demonstrate that these late learners consistently fail to show native-like sensitivity to gender violations. This appears to be due to a combination of differences from the gender marking in their L1 and the relatively opaque Dutch (...)

  31. Chaotic neuron dynamics, synchronization, and feature binding: Quantum aspects.F. Tito Arecchi - 2003 - Mind and Matter 1 (1):15-43.
    A central issue of cognitive neuroscience is to understand how a large collection of coupled neurons combines external signals with internal memories into new coherent patterns of meaning. An external stimulus localized at some input spreads over a large assembly of coupled neurons, building up a collective state univocally corresponding to the stimulus. Thus, the synchronization of spike trains of many individual neurons is the basis of a coherent perception. Based on recent investigations of homoclinic chaotic systems and (...)

    To learn a visual code in an unsupervised manner, one may attempt to capture those features of the stimulus set that would contribute significantly to a statistically efficient representation. Paradoxically, all the candidate features in this approach need to be known before statistics over them can be computed. This paradox may be circumvented by confining the repertoire of candidate features to actual scene fragments, which resemble the “what+where” receptive fields found in the ventral visual stream in primates.

    Acoustic Correlates of English Lexical Stress Produced by Chinese Dialect Speakers Compared to Native English Speakers.Xingrong Guo - 2022 - Frontiers in Psychology 13:796252.
    English second language learners often experience difficulties in producing native-like English lexical stress. It is unknown which acoustic correlates, such as fundamental frequency (F0), duration, and intensity, are the most problematic for Chinese dialect speakers. The present study investigated the prosodic transfer effects of first language (L1) regional dialects on the production of English stress contrasts. Native English speakers (N = 20) and Chinese learners (N = 60) with different dialect backgrounds (Beijing, Changsha, and Guangzhou dialects) produced the same (...) including both trochaic and iambic patterns. Results showed that (a) all participants produced the stressed syllable with greater values of F0, duration, and intensity; (b) Native speakers of English employed an exquisite combination of F0, duration, and intensity, while the dialect groups transfer their native prosody into their production of English lexical stress, resulting in the deviation or abnormality of acoustic cues. Results suggest that L1 native dialect background is considered as a potentially influential factor which may transfer in L2 speech encoding and decoding process. (shrink)

    Dynamics Versus Development in Numerosity Estimation: A Computational Model Accurately Predicts a Developmental Reversal.Dan Kim & John E. Opfer - 2021 - Cognitive Science 45 (10):e13049.
    Perceptual judgments result from a dynamic process, but little is known about the dynamics of number‐line estimation. A recent study proposed a computational model that combined a model of trial‐to‐trial changes with a model for the internal scaling of discrete numbers. Here, we tested a surprising prediction of the model—a situation in which children's estimates of numerosity would be better than those of adults. Consistent with the model simulations, task contexts led to a clear developmental reversal: children made more adult‐like, (...)

    A number of ways of taxonomizing human learning have been proposed. We examine the evidence for one such proposal, namely, that there exist independent explicit and implicit learning systems. This combines two further distinctions, (1) between learning that takes place with versus without concurrent awareness, and (2) between learning that involves the encoding of instances (or fragments) versus the induction of abstract rules or hypotheses. Implicit learning is assumed to involve unconscious rule learning. We examine the evidence for implicit learning (...)

    Beyond the Basics: The Evolution and Development of Human Emotions.Robyn Bluhm - 2006 - Canadian Journal of Philosophy 36 (sup1):73-94.
    The suggestion that at least some emotions are modular captures a number of our intuitions about emotions: they are generally fast responses to a stimulus, they are involuntary, and they are easily distinguished from one another; we simply know that, for example, anger feels different than fear. Candidates for modular emotions are usually the so-called “basic” emotions - anger and fear are good examples of these. Defenders of emotion theories that focus on basic emotions, such as Paul Ekman in (...)

    Multi‐Scale Contingencies During Individual and Joint Action.J. Scott Jordan, Daniel S. Schloesser, Jiuyang Bai & Drew Abney - 2018 - Topics in Cognitive Science 10 (1):36-54.
    The present paper describes a joint action paradigm in which individuals or pairs utilized two computer keys to keep a dot stimulus moving inside a larger rectangle. Members of a pair could neither see nor hear each other. This paradigm allowed us to combine the discrete-trial type dependent variables commonly utilized by representational theorists, with the continuous, temporal dependence variables utilized by dynamical theorists. Analysis revealed that individuals kept the dot in the rectangle longer than dyads and did so (...)

    Shared and Unshared Feature Extraction in Major Depression During Music Listening Using Constrained Tensor Factorization.Xiulin Wang, Wenya Liu, Xiaoyu Wang, Zhen Mu, Jing Xu, Yi Chang, Qing Zhang, Jianlin Wu & Fengyu Cong - 2021 - Frontiers in Human Neuroscience 15.
    Ongoing electroencephalography signals are recorded as a mixture of stimulus-elicited EEG, spontaneous EEG and noises, which poses a huge challenge to current data analyzing techniques, especially when different groups of participants are expected to have common or highly correlated brain activities and some individual dynamics. In this study, we proposed a data-driven shared and unshared feature extraction framework based on nonnegative and coupled tensor factorization, which aims to conduct group-level analysis for the EEG signals from major depression disorder patients (...)

    A Model‐Based Approach to the Wisdom of the Crowd in Category Learning.Irina Danileiko & Michael D. Lee - 2018 - Cognitive Science 42 (S3):861-883.
    We apply the “wisdom of the crowd” idea to human category learning, using a simple approach that combines people's categorization decisions by taking the majority decision. We first show that the aggregated crowd category learning behavior found by this method performs well, learning categories more quickly than most or all individuals for 28 previously collected datasets. We then extend the approach so that it does not require people to categorize every stimulus. We do this using a model‐based method that (...)

    Tracking Proactive Interference in Visual Memory.Tom Mercer, Ruby-Jane Jarvis, Rebekah Lawton & Frankie Walters - 2022 - Frontiers in Psychology 13.
    The current contents of visual working memory can be disrupted by previously formed memories. This phenomenon is known as proactive interference, and it can be used to index the availability of old memories. However, there is uncertainty about the robustness and lifetime of proactive interference, which raises important questions about the role of temporal factors in forgetting. The present study assessed different factors that were expected to influence the persistence of proactive interference over an inter-trial interval in the visual recent (...)

    Neural Mechanisms of Observational Learning: A Neural Working Model.Weixi Kang, Sònia Pineda Hernández & Jie Mei - 2021 - Frontiers in Human Neuroscience 14.
    Humans and some animal species are able to learn stimulus-response associations by observing others' behavior. It saves energy and time and avoids the danger of trying the wrong actions. Observational learning depends on the capability of mapping the actions of others into our own behaviors, processing outcomes, and combining this knowledge to serve our goals. Observational learning plays a central role in the learning of social skills, cultural knowledge, and tool use. Thus, it is one of the fundamental processes (...)

    Attention Modulates Spatial Precision in Multiple‐Object Tracking.Nisheeth Srivastava & Ed Vul - 2016 - Topics in Cognitive Science 8 (1):335-348.
    We present a computational model of multiple-object tracking that makes trial-level predictions about the allocation of visual attention and the effect of this allocation on observers' ability to track multiple objects simultaneously. This model follows the intuition that increased attention to a location increases the spatial resolution of its internal representation. Using a combination of empirical and computational experiments, we demonstrate the existence of a tight coupling between cognitive and perceptual resources in this task: Low-level tracking of objects generates bottom-up (...)

  47. A cross-order integration hypothesis for the neural correlate of consciousness.Uriah Kriegel - 2007 - Consciousness and Cognition 16 (4):897-912.
    One major problem many hypotheses regarding the neural correlate of consciousness, face is what we might call “the why question”: why would this particular neural feature, rather than another, correlate with consciousness? The purpose of the present paper is to develop an NCC hypothesis that answers this question. The proposed hypothesis is inspired by the cross-order integration theory of consciousness, according to which consciousness arises from the functional integration of a first-order representation of an external stimulus and a second-order (...)

    The impact of different age-friendly smart home interface styles on the interaction behavior of elderly users.Chengmin Zhou, Yawen Qian, Ting Huang, Jake Kaner & Yurong Zhang - 2022 - Frontiers in Psychology 13.
    Smart homes create a beneficial environment for the lives of elderly people and enhance the quality of their home lives. This study aims to explore the design of age-friendly interfaces that can meet the emotional needs of self-care elderly people from the perspective of functional realization of the operating interface. Sixteen elderly users aged fifty-five and above were selected as subjects with healthy eyes and no excessive drooping eyelids to obscure them. Four representative age-friendly applications with different interface designs were (...)

  49. Depth perception from pairs of overlapping cues in pictorial displays.Birgitta Dresp, Severine Durand & Stephen Grossberg - 2002 - Spatial Vision 15:255-276.
    The experiments reported herein probe the visual cortical mechanisms that control near–far percepts in response to two-dimensional stimuli. Figural contrast is found to be a principal factor for the emergence of percepts of near versus far in pictorial stimuli, especially when stimulus duration is brief. Pictorial factors such as interposition (Experiment 1) and partial occlusion Experiments 2 and 3) may cooperate, as generally predicted by cue combination models, or compete with contrast factors in the manner predicted by the FACADE (...)

  50. Interaction of color and geometric cues in depth perception: When does red mean "near"?Christophe Guibal & Birgitta Dresp - 2004 - Psychological Research 69:30-40.
    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 (...)
