Sit-and-Wait Strategies in Dynamic Visual Search [PDF]

, 2003
The role of memory in visual search has lately become a controversial issue. Horowitz and Wolfe (1998) observed that performance in a visual search task was little affected by whether the stimuli were static or randomly relocated every 111 ms.

Probabilistic Motion Estimation Based on Temporal Coherence [PDF]

, 2000
We develop a theory for the temporal integration of visual motion motivated by psychophysical experiments. The theory proposes that input data are temporally grouped and used to predict and estimate the motion flows in the image sequence.

Identifying individual's distractor suppression using functional connectivity between anatomical large-scale brain regions

NeuroImage
Distractor suppression (DS) is crucial in goal-oriented behaviors, referring to the ability to suppress irrelevant information. Current evidence points to the prefrontal cortex as an origin region of DS, while subcortical, occipital, and temporal regions

Context Modulates Congruency Effects in Selective Attention to Social Cues

Frontiers in Psychology, 2018
Head and gaze directions are used during social interactions as essential cues to infer where someone attends. When head and gaze are oriented toward opposite directions, we need to extract socially meaningful information despite stimulus conflict ...

Negative emotional stimuli reduce contextual cueing but not response times in inefficient search [PDF]

, 2014
In visual search, previous work has shown that negative stimuli narrow the focus of attention and speed reaction times (RTs). This paper investigates these two effects by first asking whether negative emotional stimuli narrow the focus of attention to ...

Motion adaptation and attention: A critical review and meta-analysis [PDF]

, 2019
The motion aftereffect (MAE) provides a behavioural probe into the mechanisms underlying motion perception, and has been used to study the effects of attention on motion processing.

A search order lost effect: Ignoring a singleton distractor affects visual search efficiency

Vision Research, 2010
Four experiments investigated after-effects of attentional capture by a target-feature singleton distractor. In Experiments 1 and 3, participants searched for an orientation singleton target in a visual display and responded to a reported-attribute in the target (a compound search task).

Treatment timing and multidisciplinary approach in Apert syndrome [PDF]

, 2015
Apert syndrome is a rare congenital disorder characterized by craniosynostosis, midface hypoplasia and symmetric syndactyly of hands and feet. Abnormalities associated with Apert syndrome include premature fusion of coronal sutures system (coronal ...
