The Formation of Equivalence Classes as Function of Number of Familiar Stimuli

Previous experiments have investigated the importance of using pictures as C stimuli in equivalence class formation. Findings have indicated that, pictures used as C stimuli have shown to be the most efficient in producing equivalence class formation relative to when all stimuli set are abstract. This study extends the literature further by examining the extent to which the number of C as pictures stimuli leads to equivalence class formation. Sixty participants were randomly assigned equally to four experimental conditions: No Picture Group, 1-Picture Group, 2-Pictures Group, and 3-Pictures Group. The findings from the experiment showed that 2 of 15 participants in the Abstract Group formed classes. In addition, 2 of 15 participants in the 1-Picture Group formed classes, 8 of 15 participants in the 3-Pictures Group formed classes, and lastly 12 of 15 members in the 3-Pictures Group formed classes. The statistical analysis showed that equivalence class formation is a function of the number of pictures.
