question 31

Multiple Choice

Posner, Snyder, and Davidson (1980) examined spatial attention using arrows as a prime. Most of the time, the arrow pointed to the area where the stimulus would appear, but 20% of the time it did not. They compared reaction times (RT) when the cue was valid, when it was invalid, and when a neutral cue was presented. Which of the following results was NOT supported by their findings?

• A) RTs were slower in the invalid condition relative to the valid condition.
• B) Spatial attention is limited in capacity.
• C) We can attend to two different locations without a reduction in performance.
• D) RTs were faster for valid responding relative to neutral responding.
