Sequence redundancy,rating dimensions,and the exposure effect

Two experiments investigated Zajone’s (1968) hypothesis that mere repeated exposure to stimuli is a sufficient condition to enhance individuals’ attitudes toward those stimuli. In the first experiment, no significant differences in preference were obtained following exposure to high- and low-redundancy sequences of nonsense syllables. In the second study, the effects of repeated exposure were measured along several rating dimensions, revealing significant differences between dimensions. These results were discussed in terms of the limiting conditions of the exposure effect.
