Egly, Driver, & Rafal had participants look at displays that featured two rectangles (A and B) standing on end, equidistant from a central fixation point. On a given trial, a target stimulus was presented at the top or bottom of one of the rectang
Prior to the presentation of a target, one of the rectangles was highlighted, indicating that
the target position would be within this rectangle. On some trials (invalid trials), the target appeared in the non-
highlighted rectangle. On these key (invalid trials), Egly et al. found that the misleading cue _________,
supporting _________.
a) slowed reaction time; space-based views of attention
b) slowed reaction time; object-based views of attention
c) had no effect on reaction time; space-based views of attention
d) had no effect on reaction time; object-based views of attention
Question 2If attention is like a spotlight, then as attention shifts, the space along the way should be temporarily illuminated by the spotlight (temporary illumination),
and the time it takes to shift attention should be systematically related to how far the spotlight has to travel (shift time). Which of these two predictions is clearly borne out by empirical data?
a) both
b) neither
c) temporary illumination
d) shift time
Question 3For which of these numbers would you most likely count rather than subitize?
a) 0
b) 1
c) 3
d) 5
