Influence of the spacing of trait information on impressions of likability

Five experiments were conducted in which subjects were shown lists of trait adjectives that supposedly described particular individuals. Each list included both positive and negative traits, with all such traits occurring twice. The second occurrence of a trait followed the first either immediately (massed presentation) or after four other traits intervened (distributed presentation). For a given list, all positive traits received massed presentation and all negative traits were distributed, or vice versa. After list presentation, subjects judged how likable the person described would be. In Experiments 1–3 only, there was also a free recall test for the traits. The free recall test revealed both a spacing effect (distributed items being recalled better than massed) and a bias toward recalling negative traits better than positive. Likability judgments paralleled the recall pattern, with the judgments being more positive when positive traits were distributed (and negative massed), than in the opposite arrangement. Correlations calculated between recall and impressions were mostly nonsignificant, however, suggesting that judgments were not based on the recall of specific traits and that inferences formed at encoding were of primary importance.
