Cognitive processing efficiency requires both an ability to attend to task-relevant stimuli with quickness and accuracy, while also filtering distracting or task-irrelevant stimuli. This study investigated cognitive processing efficiency by using pupillary responses as an index of attentional allocation to relevant target and irrelevant masks on a visual backward masking task. The relationship ...

INTRODUCTION Patients with neglect often fail to be aware of stimuli located on their contralesional side--the side of space opposite their brain damage. Some patients show impairments in extrapersonal space; others within personal (body) space; and some in both. Although the neglect syndrome may be associated with a distorted perception of extrapersonal or personal space, recent investigations...

Background: According to metacognitive theory, Cognitive Attentional Syndrome (CAS) is a transdiagnostic factor and main mechanism of psychopathology maintenance. The goal this study examine whether CAS predicted stress- trauma-related symptomatology in the first months COVID-19 pandemic three later. Methods: Initially, 1792 participants were recruited online via social media; data collected at...

This paper is aimed at furthering discussions about the properties which computational cognitive models of attentional control should have if they are meant to be applied in interactive human-computer systems, namely for predicting human attention shifts across control levels. The paper discusses a number of issues of attentional control and implications that follow for computational modeling. ...

Biases exist in many perceptual and cognitive functions. Since visual attention plays an important role in a wide range of perceptual and cognitive processes, any bias in the spatial distribution of attention is likely to be a significant source of perceptual and cognitive asymmetries. An attentional visual field task (AVF) requiring localization of a target among distractors was used to assess...

Task-evoked pupil dilation is a measure of attentional allocation. Schizophrenia patients have pupil dilation deficits during high cognitive load tasks, which have been attributed to attentional resource deficits. Moreover, this attentional impairment is thought to be linked to cognitive fragmentation and thought disturbance. Previous attempts to associate attentional deficits to thought distur...

OBJECTIVE The aim of this study was to empirically assess the efficacy of cognitive countermeasures based on the technique of information removal to enhance human operator attentional disengagement abilities when facing attentional tunneling. BACKGROUND Lessons learned from human factors studies suggest that conflict with automation leads to the degradation of operators' performance by promot...

Attentional-interference using emotional Stroop tasks (ESTs) is greater among individuals in the general population with positive (versus negative) schizotypal traits; specifically in response to negatively (versus positively) valenced words, potentially capturing threat-sensitivity. Variability in attentional-interference as a function of subcategories of negatively valenced words (and in rela...

purpose the aim of this study was to determine the effect of one night's sleep deprivation on anaerobic performance and reaction time of subjects in the morning of the following day. methods eighteen male college student athletes were studied twice in a balanced, randomized design. subjects were measured for peak power, mean power and reaction time. results the performance showed no significant...
