Exam 7: Attention

Describe the cortical structures involved in attention. Do you think these structures contribute to voluntary or reflextive attention? Why or why not?

When spatial attention is introduced to one stimulus in a spatial array, simultaneous presentation of competing stimuli interferes less compared to the absence of spatial attention.

Visual search for targets requires the use of selective attention, whereas visual search for targets can occur without sequential attention.

The primary functional problem that results from damage to the attentional network and that produces neglect syndrome is that patients

You are chasing a tennis ball that has been hit away from you. Which of the following brain areas is least involved in tracking that stimulus?

Directing attention to a visual stimulus produces a positive ERP waveform called the P1 waveform if participants are

Attention can be directed to both spatial and nonspatial features of target visual stimuli.

Patients with neglect have deficits in attention and those with Balint's syndrome have deficits in attention.

The main deficit in Balint's syndrome is that patients can focus attention on only

The involuntary failure to attend to sensory stimuli presented on the side of space opposite to the site of brain injury in the absence of sensory problems) is called syndrome.

Your friend is looking for you and sees your face on someone else's body. This is most likely due to an error in which attentional system?

The observation that participants are actually slower to detect targets that appear at recent previously attended locations is called

Your brother sees that you are talking to a friend through a Bluetooth piece in your left ear while the news is playing out in a room. What is he likely to observe after you hang up?

Describe the subcortical structures involved in attention. Do you think these structures contribute to voluntary or reflexive attention? Why or why not?

What is the difference between voluntary attention and reflexive attention, and between overt and covert attention? Are the distinctions the same? If not, how do they differ?

Studies of attention employing the P1 waveform and the N1 waveform suggest that

is the idea that a stimulus does not have to be completely analyzed before it can be either selected for further processing or rejected as irrelevant.

The observation that extinction is worse when identical, rather than different, stimuli are simultaneously presented to the ipsilesional and contralesional sides of the visual field indicates that

Extrastriate cortical regions specialized for the processing of color, form, and motion are modulated by visual attention to these stimulus features.

In visual search tasks, the amount of time it takes to find a target among distracters is independent of the number of distracters if the target can be identified by a single feature.
