Stimulus Preexposure

Using an extension of the blocking paradigm, the question of whether operations that reduce the associability of a stimulus (preexposure, redundancy) exert their effects independently of the context in which they are experienced was examined. Prior to conditioning two of the four groups received 20 presentations (4/day for 5 days) of a visual stimulus prior to its use as a redundant element in the blocking paradigm. Preexposure occurred in the same context as the training situation for one of the groups; the other group experienced the stimulus in an altered auditory, visual and olfactory environment. The other groups served as controls: one received the blocking regimen; the other served as an overshadowing control. An altered context during preexposure enhanced the associability of the redundant cue evidenced by an attenuation of blocking. This finding suggests that one indirect effect of context is the specification of a conditional relationship between stimulus and response such that operations which alter the associability of a stimulus are dependent upon the context in which they occur.

72 college men and 72 women were given a serial search task called the Tsai-Partington Numbers Test. The design employed 3 kinds of stimulus coding and 3 forms of the test. The results indicated that no coding produced significantly better performance over coding which was either relevant or irrelevant to the task. The constant form of the test was superior to both the half-variation and total-variation forms of the test. Half and total variations were conditions in which the position of the numbers in the numerical display changed position over trials. It was suggested that coding the stimuli in these visual displays increased the difficulty of the search task regardless of the form of the test.
