The Effects of Compounds of Meaningful Stimuli on Equivalence Class Formation

Many of the experiments exploring the class enhancing effect of meaningful stimuli have so far used black and white abstract stimuli and colorful pictures. This experiment, therefore, sought to find out the effect of both colorful pictures, and black white pictures on equivalence class formation. Hence, forty-five college students were randomly assigned to three experimental conditions: No Picture, Black and White Picture, and Colorful Picture. The findings from the present experiment showed that three of 15 participants in the No Picture formed classes, 10 of 15 in Black and White Picture formed classes, and 11 of 15 in Colorful Picture formed classes. Also, the findings showed a significant difference in equivalence class formation between the No Picture Group and Black and White Picture Group, as well as between the No Picture Group and Colorful Picture Group. Furthermore, the findings showed no significant difference between the Black and White Picture Group, and the Colorful Picture Group.
