The levels hypothesis and the study of stimulus value of projective test items.

Abstract

Summary Anagrams and semantic differential (S-D) test responses of Ss for whom words were “loaded” on a free association test were compared with those of Ss for whom the words were neutral. No differences in rate of word building or mean productivity of the two groups on the anagrams test were found. Mean S-D scale values similarly failed to differentiate between the two groups. However, when numbers of neutral (0) and extreme (+3 and −3) responses were compared, “loaded” Ss were found on the whole to rate words more neutrally or more positively. The conclusion was that the stimulus value of the words in the associative condition could not be directly determined from responses in other conditions. The strategy of studying stimulus value of projective test items by using those items as stimuli on tests eliciting different levels of response was, therefore, questioned. Several other related experimental strategies which may mix response levels were also discussed and more appropriate techniques were suggested.
