Exam 7: Attention

Describe the role of attention in perception. What might you conclude based on behavioral studies? How do studies of the neural substrate inform behavioral results?

Hillyard and colleagues (1973) recorded event-related potentials (ERP) from participants while they performed a dichotic listening task. When comparing the ERPs collected when participants attended to a given signal to those collected when they ignored this signal, the researchers found that auditory ERPs

In attention experiments, cues that correctly predict the location of the target are called ________, whereas cues that predict other locations are called ________.

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

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.

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

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

When Bisiach and Luzzatti (1978) asked patients with the neglect syndrome to describe their own mental images of the Italian city in which they lived, the researchers found that

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
