An eye (region) sensitivity during early face perception: The N170 is modulated by facial context and featural fixation
Parkington, Karisa (University of Waterloo, 2017-04-20)The N170 is a face-sensitive ERP component that also demonstrates a particular sensitivity to the eyes. Specifically, the N170 responds maximally to isolated eye regions (i.e., two eyes), as well as to eye fixations within ... -
From eye to face: The impact of face outline, feature number, and feature saliency on the early neural response to faces
Parkington, Karisa B.; Itier, Roxane J. (Elsevier, 2019-11-01)The LIFTED model of early face perception postulates that the face-sensitive N170 event-related potential may reflect underlying neural inhibition mechanisms which serve to regulate holistic and featural processing. It ... -
Individual differences in recogn-eye-zing faces: Behavioural and neural underpinnings of face recognition in neurotypical and autistic adults
Parkington, Karisa (University of Waterloo, 2021-04-30)Attention to another’s eyes and face recognition are necessary building blocks for efficient social communication. Neurotypical adults show an attentional bias for the eye region and strong face recognition performance. ... -
Joint Modulation of Facial Expression Processing by Contextual Congruency and Task Demands
Aguado, Luis; Parkington, Karisa; Dieguez-Risco, Teresa; Hinojosa, José A.; Itier, Roxane J. (MDPI, 2019-05-17)Faces showing expressions of happiness or anger were presented together with sentences that described happiness-inducing or anger-inducing situations. Two main variables were manipulated: (i) congruency between contexts ... -
One versus two eyes makes a difference! Early face perception is modulated by featural fixation and feature context
Parkington, Karisa; Itier, Roxane J. (Elsevier, 2018-12-01)The N170 event-related potential component is an early marker of face perception that is particularly sensitive to isolated eye regions and to eye fixations within a face. Here, this eye sensitivity was tested further by ...
