Exam 7: Attention

ERP studies of visual and auditory attention suggest that early ERP components like the P1 and N1 are not modulated by the participant's attentional state.

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

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?

Please describe the dorsal and ventral system of attention. What role do they play in neglect?

On one trial of the Posner spatial cuing task (1980), a flash of light validly cued the location of an upcoming target and enhanced the participant's reaction time to detect that target. Which of the following statements about the participant's subsequent responding to this location is most accurate?

Injury to which brain structure results in a deficit in moving focused attention from a particular location in the visual field to another?

In exogenous cuing, the orienting of attention to the cue is driven primarily by the participant's goals.

Joan is a patient who had a stroke in her right parietal lobe and has extinction as a result of her injury. When placed in a driving simulator she would be most likely to miss which stimulus when stopped at a virtual crosswalk and staring straight ahead? (Note: For this question, assume drivers sit on the left side of the car.)

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

Patients with extinction are unable to detect a visual stimulus presented on the contralesional side of space if

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

Models of late selection hypothesize that attended and ignored inputs are processed equivalently by the perceptual system, reaching a stage of semantic analysis.

________ 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.

Which of the following phenomena is the most problematic for a strong early-selection view of attention?

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

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

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?

Alexandra believes that the effects of attention on perception occur very quickly on a fine temporal scale. Which of the following techniques should she use to investigate the changes in perceptual processing that may accompany focused attention?

The ability to direct attention independently of gaze or eye fixation is called

The term ________ refers to the operations involved when we select for further processing a limited subset of information from the total information available to us from our sensory systems and stored mental representations.
