Exam 18: Attention and Higher Cognition

Which structure is linked to the orienting and shifting of attention?

What accounts for our ability to shift rapidly between interesting objects that "pop up" in our environment and intended objects of attention?

"Inhibition of return" refers to

Which brain region plays a role in detecting and shifting attention to a novel location after target onset?

Name the subcortical and cortical areas involved in visual attention and describe their functions.

Explain the differences between top-down and bottom-up processing, using examples from voluntary and reflexive cuing tasks.

In a peripheral spatial cuing task, a valid unexpected stimulus enhances the detection of targets when the interval between the stimulus and the target is

The idea that conjunction searches involve sequential shifts of attention that help coordinate multiple cognitive feature maps is referred to as

Which attention network is responsible for top-down control of voluntary attention?

Describe the phenomenon of hemispatial neglect with regard to its primary symptoms and underlying neuropathology.

Hemispatial neglect can occur with damage to the _______ cortex.

Scientists have been able to program a computer to reconstruct an image of what a person was looking at based on a library of video clips by analyzing the specific _______ patterns previously created while the person viewed the videos.

In early selection models of attention, perceptual analysis and semantic meaning occur

Compare the two cortical networks that govern attention.

Which structure is linked to the orienting and shifting of attention and to the filtering of stimuli in attention tasks?

Describe the sequence and physiological processes related to reaction time responses to perceptual cues.

Describe the phenomenon called "inhibition of return" and explain how it may be an evolutionary adaptation.

Hillyard and colleagues found that in a dichotic tone procedure, selective attention to an auditory stimulus from one ear produced an early positive ERP deflection that was enhanced for the selectively attended input. This phenomenon is called the _______ effect.

Gallant and colleagues were able to reconstruct visual experiences by

In the _______ task, a single stimulus or stimulus location is held in an attentional spotlight.
