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 ... -
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 ...
