Standing enhances cognitive control and alters visual search.

Postural changes and the maintenance of postural stability have been shown to affect many aspects of cognition. Here we examined the extent to which selective visual attention may differ between standing and seated postures in three tasks: the Stroop color-word task, a task-switching paradigm, and visual search. We found reduced Stroop interference, a reduction in switch costs, and slower search rates in the visual search task when participants stood compared to when they sat while performing the tasks.

Motion onset really does capture attention.

Several properties of visual stimuli have been shown to capture attention, one of which is the onset of motion. However, whether motion onset truly captures attention has been debated. It has been argued that motion onset only captured attention in previous studies because properties of the animated motion used in those experiments caused it to be "jerky" (i.

Boundary Extension Is Sensitive to Hand Position in Young and Older Adults.

Objectives: Based on preliminary reports, we expected an age-related increase in boundary extension (BE), a phenomenon in which people falsely remember seeing more of a scene than was presented. Given recent data suggesting hand-centered attentional frames in young adults contrasted with body-centered attentional frames in older adults, we predicted hand-position effects on BE in young adults only.

Method: Participants (59 young, 60 older adults) viewed photographs of complex scenes (e.
