Are you as important as me? Self-other discrimination within trait-adjective processing
Hudson, Anna; Wilson, McLennon J.G.; Green, Emma S.; Itier, Roxane J.; Henderson, Heather A. (Elsevier, 2020-07-01)Healthy adults typically display enhanced processing for self- (relative to other-) relevant and positive (relative to negative) information. However, it is unclear whether these two biases interact to form a self-positivity ... -
Asymmetry in Gaze Direction Discrimination Between the Upper and Lower Visual Fields
Palanica, Adam; Itier, Roxane J. (Sage, 2017-01-06)Previous research has shown that gaze direction can only be accurately discriminated within parafoveal limits (∼5° eccentricity) along the horizontal visual field. Beyond this eccentricity, head orientation seems to influence ... -
Attention Capture by Direct Gaze is Robust to Context and Task Demands
Itier, Roxane J.; Palancia, Adam (Springer, 2012-01-10)Eye-tracking was used to investigate whether gaze direction would influence the visual scanning of faces, when presented in the context of a full character, in different social settings, and with different task demands. ... -
Attention Orienting by Gaze and Facial Expressions Across Development
Neath, Karly; Nilsen, Elizabeth S.; Gittsovich, Katarzyna; Itier, Roxane J. (APA, 2013-06)Processing of facial expressions has been shown to potentiate orienting of attention toward the direction signaled by gaze in adults, an important social–cognitive function. However, little is known about how this social ... -
Attention orienting by gaze and facial expressions across development
Neath, Karly; Nilsen, Elizabeth S.; Gittsovich, Katarzyna; Itier, Roxane J. (Ovid, 2013-06)Processing of facial expressions has been shown to potentiate orienting of attention toward the direction signaled by gaze in adults, an important social-cognitive function. However, little is known about how this social ... -
Autistic traits influence gaze-oriented attention to happy but not fearful faces
Lassalle, Amandine; Itier, Roxane J. (Taylor & Francis, 2015-01-02)The relationship between autistic traits and gaze-oriented attention to fearful and happy faces was investigated at the behavioral and neuronal levels. Upright and inverted dynamic face stimuli were used in a gaze-cueing ... -
Both fearful and happy expressions interact with gaze direction by 200 ms SOA to speed attention orienting
McCrackin, Sarah D.; Itier, Roxane J. (Taylor and Francis, 2018-01-16)Attention orienting towards a gazed-at location is fundamental to social attention. Whether gaze cues can interact with emotional expressions other than those signalling environmental threat to modulate this gaze cueing, ... -
Combined effects of inversion and feature removal on N170 responses elicited by faces and car fronts
Kloth, Nadine; Itier, Roxane J.; Schweinberger, Stefan R. (Elsevier, 2013-02-28)The face-sensitive N170 is typically enhanced for inverted compared to upright faces. Itier, Alain, Sedore, and McIntosh (2007) recently suggested that this N170 inversion effect is mainly driven by the eye region which ... -
Early sensitivity for eyes within faces: A new neuronal account of holistic and featural processing
Nemrodov, Dan; Anderson, Thomas; Preston, Frank F.; Itier, Roxane J. (Elsevier, 2014-08-01)Eyes are central to face processing however their role in early face encoding as reflected by the N170 ERP component is unclear. Using eye tracking to enforce fixation on specific facial features, we found that the N170 ... -
Effects of peripheral eccentricity and head orientation on gaze discrimination
Palanica, Adam; Itier, Roxane J. (Taylor & Francis, 2014-11-26)Visual search tasks support a special role for direct gaze in human cognition, while classic gaze judgement tasks suggest the congruency between head orientation and gaze direction plays a central role in gaze perception. ... -
Effects of task demands on the early neural processing of fearful and happy facial expressions
Itier, Roxane J.; Neath-Tavares, Karly N. (Elsevier, 2017-05-15)Task demands shape how we process environmental stimuli but their impact on the early neural processing of facial expressions remains unclear. In a within-subject design, ERPs were recorded to the same fearful, happy and ... -
Emotional modulation of attention orienting by gaze varies with dynamic cue sequence
Lassalle, Amandine; Itier, Roxane J. (Taylor & Francis, 2015-07-03)Recent gaze cueing studies using dynamic cue sequences have reported increased attention orienting by gaze with faces expressing fear, surprise or anger. Here, we investigated whether the type of dynamic cue sequence used ... -
Eye gaze and head orientation modulate the inhibition of return for faces
Palanica, Adam; Itier, Roxane J. (Springer, 2015-11-01)The present study used an inhibition of return (IOR) spatial cueing paradigm to examine how gaze direction and head orientation modulate attention capture for human faces. Target response time (RT) was measured after the ... -
Facial expression discrimination varies with presentation time but not with fixation on features: A backward masking study using eye-tracking
Neath, Karly; Itier, Roxane J. (Taylor & Francis, 2014-01-02)The current study investigated the effects of presentation time and fixation to expression-specific diagnostic features on emotion discrimination performance, in a backward masking task. While no differences were found ... -
Fearful, surprised, happy, and angry facial expressions modulate gaze-oriented attention: behavioral and ERP evidence.
Amandine, Lassalle; Itier, Roxane J. (Taylor & Francis, 2013-09-18)The impact of emotions on gaze-oriented attention was investigated in non-anxious participants. A neutral face cue with straight gaze was presented, which then averted its gaze to the side while remaining neutral or ... -
Feeling through another's eyes: Perceived gaze direction impacts ERP and behavioural measures of positive and negative affective empathy
McCrackin, Sarah D.; Itier, Roxane J. (Elsevier, 2021-02-01)Looking at the eyes informs us about the thoughts and emotions of those around us, and impacts our own emotional state. However, it is unknown how perceiving direct and averted gaze impacts our ability to share the gazer's ... -
Fixation to features and neural processing of facial expressions in a gender discrimination task
Neath, Karly; Itier, Roxane J. (Elsevier, 2015-10-01)Early face encoding, as reflected by the N170 ERP component, is sensitive to fixation to the eyes. Whether this sensitivity varies with facial expressions of emotion and can also be seen on other ERP components such as P1 ... -
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 ... -
The Gaze Cueing Effect and Its Enhancement by Facial Expressions Are Impacted by Task Demands: Direct Comparison of Target Localization and Discrimination Tasks
Chen, Zelin; McCrackin, Sarah D.; Morgan, Alicia; Itier, Roxane J. (Frontiers, 2021-03-11)The gaze cueing effect is characterized by faster attentional orienting to a gazed-at than a non-gazed-at target. This effect is often enhanced when the gazing face bears an emotional expression, though this finding is ... -
Increased Early Sensitivity to Eyes in Mouthless Faces: In Support of the LIFTED Model of Early Face Processing
Itier, Roxane J.; Preston, Frank F. (Springer, 2018-07-09)The N170 ERP component is a central neural marker of early face perception usually thought to reflect holistic processing. However, it is also highly sensitive to eyes presented in isolation and to fixation on the eyes ...
