P3b Amplitudes Differences in Ultra-Rapid Visual Categorization Task of Food and Non-Food Items
South Florida Journal of Development, Miami, v.2, n.1, p. 440-457, jan./ mar. 2021. ISSN 2675-5459 P3b amplitudes differences in ultra-rapid visual categorization task of food and non-food items DOI: 10.46932/sfjdv2n1-033 Received in: November 1st, 2020 Accepted in: December 30th, 2020 Tawhida Jahan Chairperson & Assistant professor, Department of Communication Disorders, University of Dhaka, Bangladesh Cognitive Science, TU-Kaiserslautern, Germany E-mail: [email protected] ABSTRACT P300, especially P3b, the third positive wave of EEG signal with near 350ms associated with occipito- patieto-temporal region of the brain, is mainly responsible for categorization of different objects. So, this study investigates the nature of amplitude and reaction time difference in ‘food’ and ‘no-food’ objects categorization task. Object categorization processes were investigated by measuring event-related potentials while participants were categorizing different ‘food’ and ‘no-food’ items. The EEG study of this experiment found no P3b amplitude differences for ‘food’ and ‘no-food’ category in the ultra-rapid categorization task. On the other hand, from the behavioral study we observed no significant difference in both reaction time (RT) and error rate (ER) in the above task. The result of this study is consistent with some previous experiments. For example, regarding the reaction, the findings can be compared with VanRullen & Thrope (2001) who also found no significant longer reaction time for ‘means of transport’ item in comparison with ‘animal’. The result of this study can also be interpreted from the perspective of ‘coarse-to-fine account’ hypothesis (Prass et al. 2013) which indicated that to recognize objects belong to basic level category one needs detail information with sufficient time. -

L'idea Centrale Che La Differenza Tra Un Modo Di Pensare Occidentale Ed Un
Mediterranean Journal of Clinical Psychology ISSN 2282-1619 Vol 7, n 1, 2019-Supplementum Psychology and Psychopathology of the Mask Faces in the Brain Pietro Perconti 1*, Gesualdo La Porta 1 Abstract In this paper it will be investigated the distinction – supported by experimental data – of two different degrees within the so-called face perception: 1) The automatic perception/detection of faces; 2) The recognition of a specific face, that concerns personal meanings association – a story, we could say – to that first automatic perceptual configuration. In general, the first degree is a basic perception process, a universal, innate and early capacity belonging to all human beings. It includes three face-selective regions in the brain, with the OFA and the STS who process the partial data of faces, and the FFA that “produces” the overall basic form. The second degree consists in a complex recognition process, which implies the activation of many cerebral areas with different functions such as, for example, the subcortical regions responsible for emotions modulation (amygdala, insula), the intraparietal sulcus, the auditory cortex. It associates a given perceptual pattern with specific semantic entities, which compose a qualitative complex of experience, knowledge and subjective understanding. 1 Department of Cognitive Science (COSPECS), University of Messina, Italy E-mail corresponding author: [email protected] Keywords: Face recognition; Emotion, Experience; Mind-reading; Pareidolia; Prosopagnosia; Social cognition.

It’s an essential element for the social cognition, because it actively conveys important information such as emotions, expressions, glances aimed at specific objects, and constitutes the concrete basis for the other minds intentionality reading. -
Event-Related Brain Potentials During Natural Sentence Processing
BRAIN AND LANGUAGE 11, 354-373 (1980) Reading Between the Lines: Event-related Brain Potentials during Natural Sentence Processing MARTA KUTAS AND STEVEN A. HILLYARD University of California, San Diego Event-related potentials (ERPs) were recorded from subjects as they silently read 160 different seven-word sentences, presented one word at a time. Each sentence was in itself a natural, meaningful phrase. Substantial intersubject var- iability was observed in the ERP waveshapes following the words. More than half of the subjects generated P3 components to word stimuli, but those who did showed similar responses to repeated control presentations of a single word. In addition, it was found that all but the first word in the sentence elicited an ERP with a significant left-greater-than-right asymmetry in the late positivity over temporo-parietal regions. The ERPs to the last words were associated with more late positivity than those to the preceding words. One quarter of the sentences, at random, ended with a word printed in a typeface that was different from that of the preceding words. This infrequent change in typeface elicited a complex ERP having three consistent late positive components. INTRODUCTION Reading is fundamental for the acquisition of knowledge in literate societies and a stalwart member of the three R’s Yet, we know astonish- ingly little about the neurophysiological mechanisms which enable us to read a sentence and comprehend its meaning. The only currently feasible approach to understanding normal human neurophysiology involves the recording of event-related potentials (ERPs) from the scalp. While this technique has the advantage of being nonintrusive, it provides a rather remote index of the complex neuronal activity patterns which underly human language processes. -

Wenger Associate Professor of Cognitive Psychology Thesis Advisor Cathleen M. Moore Professor of Cognitive Psychology Reginald B. Adams, Jr. Assistant Professor of Social Psychology Melvin M. Mark Professor of Social Psychology Head of the Department of Psychology * Signatures are on file in the Graduate School. ii ABSTRACT This study examined the extent to which holism in visual perception can be revealed by way of the presence or absence of crowding. Martelli, Majaj, and Pelli (2005) used crowding to propose an operational definition for holism. Specifically, they argued that holistic perception of an object is implicated if that object can be identified when the entire object is presented within an isolation field (defined as an area proportional to one-half eccentricity). Conversely, parts- based processing is implicated if identification is impaired when the entire object is within an isolation field, with an attenuation or elimination of that impairment when each part of the object is isolated by critical spacing. Martelli et al. found evidence of crowding—increases in threshold contrast as a function of eccentricity for faces and words—suggesting that foveally-presented objects are processed holistically, and peripherally-presented objects are processed by parts. -

Abstract A key challenge in understanding stories and conversations is the comprehension of ‘anaphora’, words that refer back to previously mentioned words or concepts (‘antecedents’). In psycholinguistic theories, anaphor comprehension involves the initial activation of the antecedent and its subsequent integration into the unfolding representation of the narrated event. -
Visual Speech Information for Face Recognition
Perception & Psychophysics 2002, 64 (2), 220-229 Visual speech information for face recognition LAWRENCE D. ROSENBLUM, DEBORAH A. YAKEL, NASER BASEER, ANJANI PANCHAL, BRYNN C. NODARSE, and RYAN P. NIEHUS University of California, Riverside, California Two experiments test whether isolated visible speech movements can be used for face matching. Vis- ible speech information was isolated with a point-light methodology. Participants were asked to match articulating point-light faces to a fully illuminated articulatingface in an XAB task. The first experiment tested single-frame static face stimuli as a control. The results revealed that the participants were sig- nificantly better at matching the dynamic face stimuli than the static ones. Experiment 2 tested whether the observed dynamic advantage was based on the movement itself or on the fact that the dynamic stimuli consisted of many more static and ordered frames. For this purpose, frame rate was reduced, and the frames were shown in a random order, a correct order with incorrect relative timing, or a correct order with correct relativetiming. The results revealedbettermatching performance with the correctly ordered and timed frame stimuli, suggesting that matches were based on the actual movement itself. These findings suggest that speaker-specificvisible articulatory style can provide information for face matching.
