Abstract
The goal of Study I was to address the current gap in research concerning the lack of validation studies for rated stimuli. The mean ratings from two samples for 192 words were calculated. Results indicated that the rating means between samples were positively related (r = .96, p < .01). If rated stimuli are not substantiated, stimuli would become subjective and lose objectivity as tools of measurement. The first goal of Study II was to address the lack of collections for rated everyday objects. A total of 180 everyday objects were compiled and rated according to valence, arousal, and survival. The second goal was to examine how these dimensions were related. A significant change between Model 1 (R 2= .05, F (1,178) = 8.90, p <.01) and Model 2 (R2 = .42, F (2,177) = 64.71, p <.01) indicated a curvilinear relationship between arousal and valence. Results also indicated a positive relationship for arousal and survival (r = .17, p < .05) but indicated no relationship between valence and survival (r = .04, p = .64). Compiling collections of stimuli, examining how dimensions are related, and investigating if ratings compare across samples are important endeavors for the field of psychology.
