Person organization with a memory set: are spontaneous trait inferences personality characterizations or behaviour labels?
Recent research on impression formation has demonstrated that perceivers can categorize the action of target actors in terms of the traits that those behaviours represent, and that they do so in a spontaneous fashion, with neither the intent of categorizing nor the awareness of categorizing. This has resulted in a discussion about what these inferences refer to. Are they simple summaries of the behaviour without implications for the personalities of the people enacting those behaviours, or are they inferences about the target's disposition? The current experiment uses a procedure from the person memory literature to establish that these inferences are in fact references to the qualities of the target actors. Set size effects demonstrate that perceivers are organizing their inferred traits in person nodes; the person serves as the superordinate cue to which inferences are attached. This not only provides evidence that inferences formed spontaneously refer to the personality characteristics of the target, but also provides the first evidence of person organization under simple instructions to memorize stimulus information. The implications of the richness of the target information for spontaneously forming person inferences and for person organization in general are discussed.
