Document Summary
Attention: selective attention: the form of attention involved when processing is restricted to a subset of the possible stimuli. Selection in space: curing as a tool for examining attention, posner cueing paradigm, simple probe detection experiment, cues are valid or invalid. Rts are shorter on valid cue trials. Rts are longer on invalid cue trials. Spotlight theory: egly, rafal & driver (1994, spotlight prediction, fastest rts for 1 field parietal love lesion. Typically, neglect of the left visual field after damage to the right. Contralesional field: the visual field on the side opposite a brain: for example, points to the left of fixation are contralesional to damage to the right hemisphere of the brain. Spotlight model: attention is restricted in space and moves from one point to the next. Zoom lens model: the attended region can grow or shrink depending on the size of the area to be processed.
