Quintino R. Mano, Gregory G. Brown, Khalima Bolden, Robin Aupperle, Sarah Sullivan, Martin P. Paulus, Murray B. Stein
2013 Cognition & Emotion  
Accumulating evidence suggests that working memory load is an important factor for the interplay between cognitive and facial-affective processing.  ...  Facial distracters displayed happy, sad, or neutral expressions in Experiment 1 (N=60) and happy, fearful, or neutral expressions in Experiment 2 (N=29).  ...  The authors would also like to thank the anonymous reviewers for their thoughtful comments and suggestions to improve the quality of the manuscript.  ...

Event-related brain potential correlates of emotional face processing

Martin Eimer, Amanda Holmes
2007 Neuropsychologia  
Emotional facial expressions are particularly salient stimuli for conveying important nonverbal communications to other species members, and, in humans, are immediate indicators of affective dispositions  ...  Results from recent event-related brain potential (ERP) studies investigating brain processes involved in the detection and analysis of emotional facial expression are reviewed.  ...  The authors thank two anonymous reviewers for helpful comments.  ...

Effects of outdoor lighting on judgements of emotion and gaze direction

S Fotios, B Yang, C Cheal
2013 Lighting Research and Technology  
Results for judgements of emotion from facial expression suggest a minimum luminance of the face of 0.1-1.0 cd/m 2 if facial expressions are to be identified accurately at 4 m, but a luminance above 1.0  ...  The results were used to estimate appropriate light levels for outdoor lighting.  ...  database developed by the Laboratory for Cognitive and Affective Neuroscience in Tilburg University, and the uulmHPG database developed by the Institute of Neural Information Processing in University  ...

Quantifying Facial Expression Intensity and Signal Use in Deaf Signers

2019 Journal of Deaf Studies and Deaf Education  
Our results provide a robust benchmark for the intensity and signal use in deafness and novel insights into the differential coding of facial expressions of emotion between hearing and deaf individuals  ...  Yet, it remains unclear how facial expressions are decoded by deaf adults in the absence of an auditory sensory channel.  ...  The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.  ...
