Exposure duration as a confounding methodological factor in projective testing.
Exposure duration has been found to have a strong impact on the affective value attributed to a variety of stimuli. The purpose of the study reported here was to examine the impact of this variable in projective testing, and im particular in the affective value subjects attribute to the TAT cards. Using 34 undergraduate students, a linear decrease in pleasantness was found as a function of exposure duration. Factors leading to variation in exposure duration might therefore be confounded with the interpretations made of a subject's protocol. It was suggested that the time a subject views a projective test stimulus should be controlled in the administration.
