| Abstract: | It is suggested that 1 response-influencing variable in psychological experiments may be the individual S's need for sensory variation as manifested in alternation behavior. The proposition is put forth that in an experimental situation where a discriminatory response to one of a series of successively presented stimuli is required, the organism will seek to optimize the amount of stimulus variability or complexity by alternation behavior.
