PSY 3051 Lecture 4: Attention II
Document Summary
Posner cueing paradigm: you can attend to something without looking directly at it, peripheral cueing. Cue shows up on left or right while looking at center: central cueing. Cue shows up in center prompting look at left or right. Occurs even when information is not important: endogenous (voluntary) How much the attention shifts depends on the form of an object. Dividing attention is easier with the same object than with separate objects. Comparing properties is easier when they come from the same object: baylis & driver (1993) Neglect patients may have some form of object-based attention deficits as well as space-based attention deficits: after the brain damage, neglect may give way to extinction, a milder form of neglect. Perceptual loss only noticed when there are two separate objects to attend to. They will see both sides of one object but only one of two objects. Connecting the two objects reduces or eliminates neglect.
