How Attention Affects Spatial Resolution.
We summarize and discuss a series of psychophysical studies on the effects of spatial covert attention on spatial resolution, our ability to discriminate fine patterns. Heightened resolution is beneficial in most, but not all, visual tasks. We show how endogenous attention (voluntary, goal driven) and exogenous attention (involuntary, stimulus driven) affect performance on a variety of tasks me...
متن کاملHow Visual Information Affects a Spatial Task
To examine the information content of mental representations of three-dimensional objects, 21 participants performed a mental rotation task with the classic Shepard and Metzler (1971) figures. We compared conditions in which the figures were monochromatic, a condition in which they were colored consistently, and a condition in which they were colored inconsistently. Color affected performance o...
متن کاملMotivation sharpens exogenous spatial attention.
Although both attention and motivation affect behavior, how these 2 systems interact is currently unknown. To address this question, 2 experiments were conducted in which participants performed a spatially cued forced-choice localization task under varying levels of motivation. Participants were asked to indicate the location of a peripherally cued target while ignoring a distracter. Motivation...
متن کاملSpatial attention affects brain activity in human primary visual cortex.
Functional MRI was used to test whether instructing subjects to attend to one or another location in a visual scene would affect neural activity in human primary visual cortex. Stimuli were moving gratings restricted to a pair of peripheral, circular apertures, positioned to the right and to the left of a central fixation point. Subjects were trained to perform a motion discrimination task, att...
