Remembering can cause inhibition: retrieval-induced inhibition as cue independent process.

Previous experiments have mostly relied on recall as a dependent measure to assess whether retrieval of information from memory causes inhibition of related information. This study aimed to measure this inhibition in a more direct way. In Experiment 1, it was shown that repeated retrieval of exemplars from a category resulted in longer recognition latencies to nonretrieved exemplars from that same category, compared with recognition latencies to control exemplars. Experiment 2 obtained the same pattern of results using a lexical decision task. This was the 1st time that retrieval-induced forgetting was demonstrated on an implicit test of memory. To exclude noninhibitory explanations of the data, the exemplars were presented in both experiments without their categories as cues.

Mimicry and prosocial behavior.

Recent studies have shown that mimicry occurs unintentionally and even among strangers. In the present studies, we investigated the consequences of this automatic phenomenon in order to learn more about the adaptive function it serves. In three studies, we consistently found that mimicry increases prosocial behavior. Participants who had been mimicked were more helpful and generous toward other people than were nonmimicked participants. These beneficial consequences of mimicry were not restricted to behavior directed toward the mimicker, but included behavior directed toward people not directly involved in the mimicry situation. These results suggest that the effects of mimicry are not simply due to increased liking for the mimicker, but are due to increased prosocial orientation in general.

When stereotypes get in the way: stereotypes obstruct stereotype-inconsistent trait inferences.

There is a growing body of evidence indicating that people spontaneously make trait inferences while observing the behavior of others. The present article reports a series of 5 experiments that examined the influence of stereotypes on the spontaneous inference of traits. Results consistently showed weaker spontaneous trait inferences for stereotype-inconsistent behavioral information than for stereotype-consistent and stereotype-neutral information. Taken together, the current results suggest that specific spontaneous trait inferences become obstructed by inhibitory processes when behavior is inconsistent with an already activated stereotype. These findings are discussed in relation to stereotype maintenance processes and recent models of attribution in social judgment.

Literal and symbolic immortality: the effect of evidence of literal immortality on self-esteem striving in response to mortality salience.

Three studies investigated the effect of encouraging participants to believe in an afterlife on the relationship between mortality salience and self-esteem striving. Participants were exposed to essays arguing either in favor of or against the existence of an afterlife, and reminded about death or a control topic. Mortality salience led to increased accuracy ratings of a positive personality description (Studies 1 and 2) and increased striving for and defense of values (Study 3) among participants who read the essay arguing against an afterlife, but not among participants who read the essay in favor of it. The implications for the terror management analysis of self-esteem, the appeal of immortality beliefs, and the interplay between self-esteem striving and spiritual pursuits are discussed.

It takes two to mimic: behavioral consequences of self-construals.

The present studies demonstrated the moderation of self-construal orientation on mimicry. Recent research has indicated that an interdependent self-construal is associated with assimilation of the other to the self whereas an independent self-construal is associated with minimizing the influence of others on the self (H. R. Markus & S. Kitayama, 1991; D. Stapel & W. Koomen, 2001). Therefore, the authors hypothesized that an interdependent self-construal would be associated with more mimicry than an independent self-construal. When self-construal orientations were experimentally primed, as in Studies 1 and 2, independent self-construals produced less nonconscious mimicry than interdependent self-construals. When self-construals were examined as cultural differences with either a chronically dominant independent (Americans) or interdependent (Japanese) construal of the self, these results were replicated.
