Multiple Choice

Refer to the figure.
Which statement explains the significance of the results shown in the figure?

• A) Due to inhibition of return, the longer reaction time after an invalid stimulus is directly proportional to the delay between the invalid stimulus and the target stimulus.
• B) When the delay between a valid cue and the target stimulus is long, subjects focus everywhere else, lengthening their reaction time for detecting the target.
• C) The phenomenon in which shorter times between a valid stimulus and the appearance of the target stimulus are associated with shorter reaction times for detecting the target stimulus is called inhibition of return.
• D) Once a subject has looked toward a stimulus, their ability to detect a target stimulus in the same location is inhibited.
