Exam 7: Attention

During a particularly boring lecture, you carefully note the time on a clock that is mounted on the side wall of the classroom while keeping your eyes fixated on the professor's face. This is an example of

In one of the earliest studies of visual attention, Helmholtz 1894) constructed a screen on which letters were painted at various distances from the center. Following a brief illumination, he found that

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

On one trial of the Posner spatial cuing task, 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?

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.)

Both early- and late-selection models of attention share the idea that

Describe the basic findings of the visual search research conducted by Treisman and colleagues. In particular, describe the difference between a feature search and a conjunction search. Draw a figure illustrating a typical response-time pattern for the two search types.

Can object representations modulate spatial attention? Please describe evidence to support your answer.

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.

In dichotic listening studies, it has been found that a participant usually notices when his or her own name is embedded in the ignored channel. This finding is considered evidence that

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

One finding demonstrated by the Posner spatial cuing task 1980) is that

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

All of the following describe differences between early-selection and late-selection models of attention EXCEPT

Which component of attention is associated with the pulvinar?

The Posner spatial cuing task 1980) showed that cuing participants to the location of an upcoming target

The process of directing one's attention to a specific external stimulus is called

The P1 ERP is associated most closely with the

How do early- and late-selection models of attention differ? Propose a dichotic listening experiment that would provide evidence to distinguish between these two models.

You are looking for a friend who is supposed to meet you in a crowded lecture hall. You know that she is wearing a bright purple sweater and glasses. Which kind of visual search best describes this situation?
