Abstract : The perceptual behavior of 8-, 9-, and 10-week-old infants as a function of different stimulus forms, individuality, and activation level was observed by means of a time-sampling rating method. The proportion of variance accounted for by differences between stimuli is found to increase with age; at the same time the effect of autonomic activation processes is decreasing. At 10 weeks but not at 8 weeks of age, circular forms elicit a relaxed approaching tendency, in contrast to a tense aversion, which is elicited by irregularly-shaped forms. (Author)
