Posner,Snyder,and Davidson (1980)examined spatial attention using arrows as primes.In most of the trials the arrow pointed to the area where the stimulus would appear a moment later,but 20% of the time it did not.They compared reaction times (RTs)for trials when the cue correctly pointed to the stimulus location,for trials when the arrow pointed toward an incorrect position,and for trials with a neutral cue (no arrow).Which of the following statements was NOT supported by their findings?

Question

Quizplus · Accepted Answer

The findings of Posner, Snyder, and Davidson (1980) supported all of the other statements. RTs were slower when the arrow pointed toward an incorrect location (A), indicating that spatial attention is sensitive to the direction of the cue. Spatial attention is limited in capacity (B), as evidenced by slower RTs when the cue was neutral compared to when it correctly pointed to the stimulus location. However, the researchers did not find evidence to support the statement that we can attend to two different locations without a reduction in performance (C).
