Exam 9: Visual Attention

Attentional capture is the process whereby a salient stimulus causes us to shift attention to that stimulus.

In the oddball procedure, an infant is shown a series of pictures of related objects, such as different kinds of balls.Then the infant is presented with an object from a different category, such as a toy animal.Research finds that ______.

The processes of attention that allow us to focus on one source when many are present are known as ______.

Give an example from your everyday life of change blindness.

Which of the following is an example of inattentional blindness?

Drew, Võ, and Wolfe (2013) used expert radiologists as their test participants.The stimuli were CT scans taken to determine if patients had dangerous nodules on their lungs.What happened in the study?

Divided attention is the process of attention that allows us to focus on one source when many are present.

What is the name of the neurological condition caused by damage to both the left and right posterior parietal lobes, which results in a limited ability to localize objects in space?

Screeners at airports must look for forbidden objects, such as knives, among the great many combs and toothbrushes passing through their screening machines.What task does this most resemble?

Simultagnosia is ______.

In their experiment, Simons and Chabris (1999) asked participants to watch a video that shows three young college-age adults wearing white T-shirts, passing a basketball, and three young college-age adults wearing black T-shirts, passing another basketball.They found that participants could not accurately track the passes when a person in a gorilla suit interrupted the game.

Change blindness is the difficulty we experience in detecting differences between two visual stimuli that are identical except for one or more changes to the image.

Moran and Desimone (1985) conducted a single-cell recording experiment with rhesus monkeys.Monkeys were trained to keep their eyes fixated on a central point and to then, as in the Posner paradigm, to attend to objects in one of two locations they were not directly looking at.They found that ______.
