On sensation, perception and thought: A reply to Rönnberg

A traditional partition of cognitive phenomena into sensation, perception and thought is reintroduced in response to recent arguments (Rönnberg, 1990) for conditions that must be met in order to distinguish between perception and cognition. The suggested division seems grossly compatible with Ronnberg's basic aim and receives support from several different lines of inquiry, including single cell recordings in the brain, neurospsychology, computational studies of vision and experimental psychology.     

Beliefs,personality, and person perception: A theory of individual differences

The hypothesis tested was that we attend to aspects of our interpersonal environment that correspond to prominent features of our own personality. One hundred fifty-four men and women rated the way in which they typically communicate and interact with significant other people (e.g., mother, father, lover) on 11 bipolar adjective scales and the way in which those other people interact with them. An individual differences multidimensional scaling analysis of interstimulus distances among the significant other people based on the ratings of the subject's interaction with those other people indicated that subjects who weighted a particular dimension tended to think they possessed a personality trait corresponding to the dimension. Reasons for the individual difference hypothesis were given.     

Exposure effects in person perception: Familiarity,similarity, and attraction

Two experiments explored the relationship between familiarity, similarity, and attraction. In the first experiment, subjects viewed photographs of faces at various exposure frequencies and then rated them for likeableness and similarity. Familiar people were regarded by the subjects as both more likeable and more similar to themselves. The effects of familiarity on perceived similarity were primarily mediated by changes in attraction, although some evidence of a direct link between familiarity and perceived similarity was also found. In the second experiment, subjects viewed the same stimuli at a single exposure frequency, and received bogus information regarding the similarity of the people shown therein. Subsequent ratings of likeableness and perceived familiarity revealed that people who seemed similar to the subjects were regarded as both more likeable and more familiar. The effects of similarity on perceived familiarity were almost entirely mediated by changes in attraction. Some of the theoretical implications of these findings are discussed.     

A matter of design: Priming context and person perception

A matter of considerable debate is whether people spontaneously use categorical knowledge (i.e., stereotypes) to guide their interactions with others. Despite initial evidence for the unconditional automaticity of category activation, recent research has identified a range of factors that moderate this process. Extending this line of inquiry, the current investigation explored the extent to which contextual influences—specifically the order in which priming stimuli are presented to participants—may modulate person categorization. Using a standard semantic-priming paradigm to index category and stereotype activation, participants were presented with priming stimuli that were either intermixed or blocked by sex. The results revealed that: (i) category and stereotype activation are moderated by the order in which priming stimuli are presented; and (ii) priming effects decrease monotonically as a function of category repetition. The theoretical implications of these findings are considered.     

A case of hand waving: Action synchrony and person perception

While previous research has demonstrated that people’s movements can become coordinated during social interaction, little is known about the cognitive consequences of behavioral synchrony. Given intimate links between the systems that regulate perception and action, we hypothesized that the synchronization of movements during a dyadic interaction may prompt increased attention to be directed to an interaction partner, hence facilitate the information that participants glean during a social exchange. Our results supported this prediction. Incidental memories for core aspects of a brief interaction were facilitated following in-phase behavioral synchrony. Specifically, participants demonstrated enhanced memory for an interaction partner’s utterances and facial appearance. These findings underscore the importance of action perception to social cognition.     

Figural emphasis and person perception

Based on Jones and Nisbett's (1972) proposition that actor-observer differences in causal attributions derive from differences in attentional focus, it was hypothesized that observers' focus of attention would influence their causal attributions for an actor's behavior. More specifically, it was predicted that the behavior of an actor who was the focus of attention by virtue of some salient physical attribute would be attributed by observers more to dispositional causes and less to situational causes than would the behavior of a less physically salient actor. The manipulations of physical salience were based upon Gestalt laws of figural emphasis in object perception. They included brightness (Study I), motion (Study II), pattern complexity (Study III), and contextual novelty (Studies IV and V). The results revealed that the salinece of the actors' environments (i.e., the other people present) rather than the salience of the actor him/herself had the most consistent influence on causal attributions. When environmental salience was high, behavior was attributed relatively more situationally than when it was low. Prior research findings are considered in light of the proposition that causal attributions for an actor's behavior vary only with the salience of his/her environment, and additional implications of this phenomenon are suggested. Some ambiguities in the application of Gestalt principles to the perception of people are discussed.     

Person, situation, and person-by-situation interaction components in person perception

The hypothesis that people store situation and person-by-situation interaction information as well as trait information about one another's behavior was tested by administering modified S-R Inventories of Anxiousness and Hostility to 54 male and 59 female undergraduates. Subjects rated the strength of affect that would be evoked by a series of situations in the two same-sex college students whom they knew best, the best-known opposite-sex person, a casually known same-sex person, and the “average college student.” Indices were constructed to measure the extent of (a) perceived average differences among people (traits), (b)perceived average differences over situations, and (c) perceived person-by-situation interaction. Analyses of variance showed that: (a) the ratings of the two best-known same-sex persons and the best-known opposite-sex person contained more interactive information than did the ratings of a casually known person and (b) females perceived more situational variability in the behavior of their own sex than did males. The amount of perceived person-by-situation interaction did not differ as a function of sex of rater or affect to be rated. It was concluded that the naive psychologist, like many professional psychologists, is an interactionist.     

Factors are fictions, and other comments on individuality theory

Three of the assumptions in Royce's (1983) theory of personality integration are examined more closely. Royce assumes that: (1) The results from factor analysis are something more than convenient ways to summarize complex covariance structures; (2) it is useful to separate cognitive, affective, sensory, motor, style, and value systems from each other; and (3) it is useful to think of normative “setpoints.” These assumptions are challenged and evidence for alternative assumptions is discussed.     

Using HyperCard to teach person perception and attribution concepts

HyperCard stacks were used to present and illustrate concepts in person perception and attribution theory. Active participation of learners was maintained through the use of interactive tutorials and simulations requiring frequent learner input. Scanned photographs, cartoons, animations, and diagrams were used to increase learner interest. Two groups of college students were tested after interaction with either the HyperCard stacks or textual materials that presented these concepts to discover the relative effectiveness of the stacks. The HyperCard group scored significantly better on an information test after a 2-h exposure to the material. The same group expressed enthusiasm, enjoyed the study experience, and voiced a desire to have more computer-assisted learning experiences, while the other group found the interaction with textual materials boring and did not look forward to a similar experience in the future.     

The intuitive personologist revisited: A critique of dialectical person perception

A critical examination of dialectical person perception as advanced by Lamiell, Foss, Trierweiler, and Leffel, (1983) reveals some important problems both in its empirical basis and in the underlying model of the intuitive personologist. The present article discusses these problems and suggests some alternative conceptions of the intuitive personologist.     

On disregarding deviants: Exemplar typicality and person perception

A pervasive problem in mental life is that of exemplar selectivity or how one isolates specific category members from other instances of a class. This problem is particupared pronounced in person perception, where perceivers may routinely want to personalize selected individuals while continuing to respond towards other members of the category in a stereotype-based manner. To realize these flexible effects, we hypothesized that, when perceivers encounter a group member, they inevitably encode an exemplar-based representation of the individual in mind. Part of this representation, moreover, is information signaling the person's goodness-of-Fit with respect to his or her salient group memberships. When the representation is activated on a subsequent occasion, these inferences of category fit moderate the extent of stereotypical thinking. The results of two studies provided converging evidence for this analysis of stereotype function. Exemplar typicality moderated both the accessibility of Stereotypic knowledge (Study 1) anxd the extent to which perceivers used a stereotype to organize information about a target (Study 2). We consider the theoretical and practical implications of these findings for our understanding of the role of stereotypes in person perception.
