There is considerable debate as to whether color singletons can capture attention in a stimulus-driven manner. In this study, we explore one potential capture enabling condition – low perceptual load. To test this hypothesis, we manipulated perceptual load in a flanker task in which flanking letters sometimes were color singletons. If low load enhances capture by color singletons, then color si...

Understanding the role of prefrontal cortex in delayed-response task performance has been a central focus of neuroimaging research. The first part of this review will emphasize consistent observations of memory-load-related effects on prefrontal cortex activity that have led me and my colleagues to propose a "memory-organization hypothesis" of prefrontal cortex function. The second part examine...

The corpus callosum has been proposed to contribute to attention by modulating resource allocation between the hemispheres and filtering interhemispheric signal transmission (M. T. Banich, 1998). The resource allocation hypothesis predicts that interhemispheric interactions become more advantageous with increasing resource demands. The selective filtering hypothesis predicts that interhemispher...

Studies on visual cognitive load have reported inconsistent effects of distractor interference when distractors have visual characteristic that are similar to the cognitive load. Some studies have shown that the cognitive load enhances distractor interference, while others reported an attenuating effect. We attribute these inconsistencies to the amount of cognitive load that a person is require...

The purpose of this work was to determine the increase limit load when resting foundation slab on ground at a different pitch piles and their length. main task is calculate combined pile-slab foundation. hypothesis that in work, bearing capacity entire structure increases. This calculated using Plaxis 3D design software complex. In article, we have determined value by which ultimate increases r...

Keeping aware of the locations of objects while one is moving requires the updating of spatial representations. As long as the objects are visible, attentional tracking is sufficient, but knowing where objects out of view went in relation to one's own body involves an updating of spatial working memory. Here, multiple object tracking was employed to study spatial updating and its neural correla...

It is now well known that the absence of attention can leave people unaware of both visual and auditory stimuli (e.g., Dalton & Fraenkel, 2012; Mack & Rock, 1998). However, the possibility of similar effects within the tactile domain has received much less research. Here, we introduce a new tactile inattention paradigm and use it to test whether tactile awareness depends on the level of percept...

This paper investigates mental workload assessment using statistical features derived from electroencephalography (EEG) signals. Mean, root mean squared, and correlation-based features are extracted from data including EEG signal recordings of five participants performing a reading task with three difficulty levels of low, medium, and high and a baseline condition. Results reveal that for the g...
