Symmetry in Emotional and Visual Similarity between Neutral and Negative Faces

Martina Riberto, Deborah Talmi, Gorana Pobric
2021 Symmetry  
The relative weight of emotional and visual dimensions in similarity judgements is still unclear.  ...  We selected 10 male faces with different expressions. Each face posed one neutral expression and one emotional expression (five disgust, five fear).  ...  We observed less low-level visual similarity between emotionally similar faces, both neutral and negative emotional, than between faces with the same identity but different emotions.  ...

Visual Mismatch Negativity and Categorization

István Czigler
2013 Brain Topography  
A higher-order perceptual category, bilateral symmetry is also represented in the memory processes underlying vMMN.  ...  As a relatively large body of research shows, violating the emotional category of human faces elicits vMMN. Another face-related category sensitive to the violation of regular presentation is gender.  ...  In 2010, Chang et al. (Experiment 1) conducted a related study with a schematic face with various emotional expressions. Neutral faces were standard stimuli, and happy and sad faces were deviants.  ...

Birds of a feather… Generalization of facial structures following massive familiarization

Pablo P.L. Tinio, Gernot Gerger, Helmut Leder
2013 Acta Psychologica  
Complexity in faces seemed to have overridden the usually positive effects of facial symmetry.  ...  Three experiments examined the effects of symmetry and complexity, as facial structures, on the aesthetic judgments of faces, and how these effects are modulated by moderate or massive familiarization.  ...  The results were similar to those of Experiment 2. Complex faces were rated as more negative in emotional valence than simple faces (Si: 3.46 vs.  ...

A Systematic Review on the Interaction between Emotion and Pseudoneglect

Francesca Strappini, Gaspare Galati, Anna Pecchinenda
2021 Symmetry  
Specifically, there is an attention-processing advantage for the left visual field in healthy, right-handed subjects, known as "pseudoneglect."  ...  Results: Fifteen studies were included, and 784 healthy participants took part in all studies reviewed.  ...  [30] used emotional primes (happy, angry, and neutral faces) and a perceptual landmark task.  ...

Repetitive transcranial magnetic stimulation over right intraparietal sulcus enhances emotional face processing in the left visual field

Chenggui Fan, Chaoyang Wan, Junjun Zhang, Zhenlan Jin, Ling Li
2018 NeuroReport  
This result suggests that rTMS over the rIPS enhances emotional face processing in the left visual field compared with neutral faces.  ...  Behavioral results demonstrated a processing advantage for emotional faces compared with neutral ones. rTMS over the rIPS caused a significant emotional difference (emotional-neutral faces) in the left  ...  All were capable of discriminating between emotion stimuli (fearful, happy, and neutral faces) in this experiment.  ...

The role of emotion in the dyad inversion effect

James W. A. Strachan, Natalie Sebanz, Günther Knoblich, Cosimo Urgesi
2019 PLoS ONE  
Holistic processing of upright face pairs occurred for neutral, happy, and sad faces but not for angry and fearful face pairs.  ...  This advantage disappears when the images are inverted, suggesting that the visual system is particularly sensitive to dyads in this upright configuration, and perceptually groups socially engaged dyads  ...  Acknowledgments Experimental scripts and raw data files are available via the following link: Author Contributions Conceptualization: James W.

Computation-Based Feature Representation of Body Expressions in the Human Brain

Marta Poyo Solanas, Maarten Vaessen, Beatrice de Gelder
2020 Cerebral Cortex  
Using representational similarity and multivoxel pattern analyses, we showed systematic relations between computation-based body features and brain activity.  ...  The discovery of midlevel body feature encoding in the brain moves affective neuroscience beyond research on high-level emotion representations and provides insights in the perceptual features that possibly  ...  In the case of symmetry, this finding was also accompanied by a high level of dissimilarity between neutral and the rest of the affective movement categories and a within-and between-category similarity  ...

Facial Feature Movements Caused by Various Emotions: Differences According to Sex

Kun Suh, Yoonkyoung Kim, Eui Lee
2016 Symmetry  
In other research, they used visual stimuli independently to elicit emotion, and the same result was derived [18] .  ...  Partala and Surakka found differences between men and women by estimated pupil accommodation [7]; when specific emotions were elicited, both sexes' pupil sizes were larger compared to the neutral state  ...  The founding sponsors had no role in the design of the study; in the collection, analyses, or interpretation of data; in the writing of the manuscript, and in the decision to publish the results.  ...

Interhemispheric ERP asymmetries over inferior parietal cortex reveal differential visual working memory maintenance for fearful versus neutral facial identities

Paola Sessa, Roy Luria, Alex Gotler, Pierre Jolicœur, Roberto Dell'acqua
2011 Psychophysiology  
These findings suggest increased maintenance in visual working memory of faces with a fearful expression relative to faces with a neutral expression and that the representational format in which fearful  ...  faces are stored in memory may be characterized by enhanced resolution relative to that subtended in the maintenance of neutral faces.  ...  When the memory and test arrays were composed of two faces, they were horizontally aligned and occupied either the upper or the lower two quadrants of the visual field, preserving the symmetry of the visual  ...

Static and Dynamic Cues to Male Attractiveness

Wilma Latuny
2021 ALE Proceeding  
In addition, we performed computational analyses of the landmark representations of faces in images and videos to determine which types of static and dynamic facial information predict the attractiveness  ...  The conclusion of the study is that thin slices of dynamical facial expressions contribute to the attractiveness of males in two ways: (i) in a positive way and (ii) in a negative way.  ...  Static and Dynamic Cues to Attractiveness The visual cues of symmetry, averageness and masculinity can all be assessed from static images of frontal faces.  ...

Gaze cueing elicited by emotional faces is influenced by affective context

Andrew P. Bayliss, Stefanie Schuch, Steven P. Tipper
2010 Visual Cognition  
Participants in the negative context produced a pattern of gaze cueing effects that were similar to that demonstrated in Experiment 1 (neutral context).  ...  It is possible that a lower degree of specificity of the negative stimuli led to a match in terms of valence between an unpleasant stimulus and a negative face, but a mismatch in the precise emotion evoked  ...  APPENDIX: DETAILS OF INTERNATIONAL AFFECTIVE PICTURE SYSTEM (IAPS) IMAGES USED Experiment 1 Neutral images  ...

Event-related potentials to changes in facial expression in two-phase transitions

Michael J. Wright, Lisa K. Kuhn, Mariska E. Kret
2017 PLoS ONE  
The purpose of the study was to compare event-related potentials (ERPs) to different transitions between emotional and neutral facial expressions.  ...  In the second experiment, comparison of neutral-happy and neutral-frightened transitions showed significantly different ERPs to emotional expression change.  ...  Other studies have found substantial differences between ERPs for emotional and neutral faces but similar responses to different emotion categories [15, 16] .  ...
