Maintaining focused attention in the classroom is considered an important factor for successful learning. Loss of instructional time due to off-task behavior is recognized as a significant challenge by both researchers and practitioners. However, there has been little research into the factors contributing to off-task behavior. This paper reports results from the first large-scale study investigating how elementary school children allocate their attention in classroom environments and how patterns of attention allocation change as a function of gender, grade level, and instructional format. The findings indicate that instructional format is related to off-task behavior in elementary school students. These findings …

Rapid manipulation of the attention field (i.e. the location and spread of visual spatial attention) is a critical aspect of human cognition, and previous research on spatial attention in individuals with autism spectrum disorders (ASD) has produced inconsistent results. In a series of three psychophysical experiments, we evaluated claims in the literature that individuals with ASD exhibit a deficit in voluntarily controlling the deployment and size of the spatial attention field. We measured the spatial distribution of performance accuracies and reaction times to quantify the sizes and locations of the attention field, with and without spatial uncertainty (i.e. the lack …

Patients with Alzheimer's disease (AD) display a multiplicity of cognitive deficits in domains such as memory, language, and attention, all of which can be clearly linked to the underlying neuropathological alterations. The typical degenerative changes occur early on in the disease in the temporal–parietal lobes, with other brain regions, such as the frontal cortex, becoming more affected as the disease progresses. In light of the importance of the parietal cortex in mediating visuospatial attentional processing, in the present study, we investigated a deficit in covert orienting of visual attention and its relationship to cortical hypoperfusion in AD. We characterized the …
