The Effect of Set Size on Color Recognition
Abstract
In two separate studies a modification of Sternberg's (13) memory task was used to study the effect of the set size of colored CRT presented stimuli on time to recognition. In both, set sizes from one to seven differently colored circles (memory set) were presented for a variable period of time. Subsequently one colored circle, that had a .50 probability of belonging to the memory set, was presented and the subject responded as to whether or not be believed it belonged to the memory set. In the first study, completely different colors, were used for each set size. Some significant rises in reaction time were found as set size increased but these were definitely not linear. In a second study, successive color sets were incremented by the addition of one color. This made the sets more similar to one another and also created a condition of over-learning for the sets. The results showed no significant differences among the set sizes from two to seven colors. Hence, it appears that for color sets that are fairly well learned, there is no significant effect of set size on time to recognition, at least for set sizes up to seven elements.
