To the extent that exposure breeds attraction, Ss in a free-choice situation should tend to repeat initially favored choices. To the extent that exposure produces boredom, Ss should tend to avoid repeating choices, at least until other stimuli have been sampled. Both tendencies were demonstrated by 20 undergraduates playing a "jukebox" of 8 initially novel musical selections over 40 trials. Ss 1st satisfied their curiosity by a systematic exploration of the stimuli. Stimulus repetitions were more frequent in later quartiles, but only repetitions in which other stimuli were allowed to intervene (higher-order repetitions) rather than immediate (1st-order) repetitions. It is concluded that both familiarity and variety preferences are satisfied by Ss who alternate among a subset of familiar stimuli. (PsycINFO Database Record (c) 2016 APA, all rights reserved)
