Visual working memory as visual attention sustained internally over time.
Visual working memory and visual attention are intimately related, such that working memory encoding and maintenance reflects actively sustained attention to a limited number of visual objects and events important for ongoing cognition and action. Although attention is typically considered to operate over perceptual input, a recent taxonomy proposes to additionally consider how attention can be...
متن کاملSpatial integration and its moderation by attention and acetylcholine.
Attention is often regarded as a mechanism by which attended objects become perceptually more salient, akin to increasing their contrast. We demonstrate by means of human psychophysics that attention is better described as a mechanism that reduces contextual integration, thereby ensuring that task irrelevant information is prevented from influencing the processing of task relevant information. ...
متن کاملSustained and transient components of focal visual attention.
Human observers fixated the center of a search array and were required to discriminate the color of an odd target if it was present. The array consisted of horizontal or vertical black or white bars. In the simple case, only orientation was necessary to define the odd target, whereas in the conjunctive case, both orientation and color were necessary. A cue located at the critical target positio...
متن کاملAuditory and visual sustained attention in Down syndrome.
BACKGROUND Sustained attention (SA) is important to task performance and development of higher functions. It emerges as a separable component of attention during preschool and shows incremental improvements during this stage of development. AIMS The current study investigated if auditory and visual SA match developmental level or are particular challenges for youth with DS. Further, we sought...
متن کاملa computer-based sustained visual attention test for pre-school children: design, development and psychometric properties
background: sustained visual attention is a prerequisite for learning and memory. the early evaluation of attention in childhood is essential for their school and career success in the future. the aim of this study was to design, development and investigation of psychometric properties (content, face and convergent validity and test-retest and internal consistency reliability) of the computer -...
