• On the Determinants of Effort 

  Dunn, Timothy (University of Waterloo, 2017-07-04)

  That humans configure their behaviors in ways to avoid effortful actions is undoubtedly one of the most pervasive hypotheses put forth to account for a wide range of human behaviors. This dissertation describes a series ...

• Shyness, Verbal Irony Comprehension, and Socio-Emotional Functioning in Middle Childhood 

  Mewhort-Buist, Tracy Anne (University of Waterloo, 2017-05-17)

• On the Effects of Disfluency in Complex Cognitive Tasks 

  Medimorec, Srdan (University of Waterloo, 2017-05-10)

  While much previous research has suggested that decreased transcription fluency has a detrimental effect on writing, there is recent evidence that decreased fluency can actually benefit cognitive processing. Across a series ...

• The Relation Between Smartphone Use and Everyday Inattention 

  Marty-Dugas, Jeremy (University of Waterloo, 2017-04-28)

  In two studies, we explored the relation between subjective reports of smartphone use and eve-ryday inattention. We created two questionnaires that measured general smartphone use (i.e. how frequently people send and receive ...

• The influence of near-miss outcomes on the physiological and subjective experience of scratch card gambling 

  Stange, Madison (University of Waterloo, 2017-04-25)

  Scratch cards are an omnipresent gambling form in the Canadian marketplace that contain a special type of outcome called a near-miss. A near-miss is an outcome that appears to come close to a large win, but falls short ...

• Adapting to Change: The Role of Priors, Surprise and Brain Damage on Mental Model Updating 

  Filipowicz, Alexandre (University of Waterloo, 2017-04-24)

  To make sense of the world, humans build mental models that guide actions and expectations. These mental models need to be receptive to change and updated when they no longer accurately predict observations from an ...

• 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 ...

• Understanding boredom proneness: Cognitive and affective correlates in healthy and traumatic brain injured individuals 

  Isacescu, Julia (University of Waterloo, 2017-03-16)

  Boredom proneness has been associated with a raft of negative cognitive, affective, and behavioural consequences. Research has sought to better understand boredom proneness from both cognitive and affective perspectives; ...

• 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 ...

• 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 ...

• Is it in the eyes? Dissociating the role of emotion and perceptual features of emotionally expressive faces in modulating orienting to eye gaze 

  Bayless, Sarah J.; Glover, Missy; Taylor, Margot J.; Itier, Roxane J. (Taylor & Francis, 2011-03-21)

  This study investigated the role of the eye region of emotional facial expressions in modulating gaze orienting effects. Eye widening is characteristic of fearful and surprised expressions and may significantly increase ...

• Species sensitivity of early face and eye processing 

  Itier, Roxane J.; Van Roon, Patricia; Alain, Claude (Elsevier, 2011-02-25)

  Humans are better at recognizing human faces than faces of other species. However, it is unclear whether this species sensitivity can be seen at early perceptual stages of face processing and whether it involves species ...

• Searching for a perceived gaze direction using eye tracking 

  Itier, Roxane J.; Palancia, Adam (Association for Research in Visison and Ophthalmology, 2011-02-01)

  The purpose of the current study was to use eye tracking to better understand the “stare-in-the-crowd effect”—the notion that direct gaze is more easily detected than averted gaze in a crowd of opposite-gaze distractors. ...

• Is the rapid adaptation paradigm too rapid? Implications for face and object processing 

  Nemrodov, Dan; Itier, Roxane J. (Elsevier, 2012-03-29)

  Rapid adaptation is an adaptation procedure in which adaptors and test stimuli are presented in rapid succession. The current study tested the validity of this method for early ERP components by investigating the specificity ...

• The role of eyes in early face processing: a rapid adaptation study of the inversion effect. 

  Nemrodov, Dan; Itier, Roxane J. (Wiley, 2011-05-23)

  The current study employed a rapid adaptation procedure to test the neuronal mechanisms of the face inversion effect (FIE) on the early face-sensitive event-related potential (ERP) component N170. Five categories of ...

• 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. ...

• 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 ...

• 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 N.; 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 ...

• 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 ...
