Distributional theories of impression formation

This paper examines theories of impression formation which represent stimulus information as distributions on subjective dimensions rather than points along a continuum. These theories explain why unfavorable information often overrides favorable information. Subjects were asked to imagine hypothetical persons described by single adjectives or adjective combinations and to estimate the probability that each person would have various degrees of likeableness. Three models were considered to describe how the likeableness distribution for the adjective combination depends on the distributions of the single adjectives. All three models assume that the mean of the distribution for the adjective combination is described by the equal probability criterion which, for symmetric distributions, implies a weighted average of the single adjective means with weights inversely proportional to their standard deviations. The models can be distinguished on the basis of the standard deviations of the adjective combinations. Estimated standard deviations of the single unfavorable adjectives were smaller than those for the single favorable adjectives. Furthermore, the standard deviation associated with an adjective combination tended to fall between the standard deviations of the single adjectives, consistent with the horizontal averaging model.     

Optimism,goals, and threats: How to conceptualize self-regulatory processes in the adoption and maintenance of health behaviors

Abstract

How individuals control themselves and their health behaviors can be better understood by examining their self-beliefs in terms of threats and goals. The distinction between self-regulatory threat appraisals and self-regulatory goal attainment may help to explain when individuals fall prey to defensive optimism and when they are guided by functional optimism. To underscore the notion of process-specific self-beliefs, a further distinction is made between goal-setting self-efficacy, action self-efficacy, coping self-efficacy, and recovery self-efficacy.     

Interpersonal distance and impression formation

Impression formation was examined as a function of interpersonal physical distance in an interview. It was predicted that a confederate would be rated less socially active as the distance between him and the subject increased. The hypothesis was supported by a significant negative linear trend in the composite ratings of friendliness, aggressiveness, extraversion, and dominance A variation in this trend, indicating that confederates seated closest to the subject were seen as less socially active, was explained in terms of compensatory behaviors minimizing the effect of close physical proximity     

Self-actualization and impression formation1

Self-actualization (SA), assessed by scores on the Personal Orientation Inventory, was related to interpersonal behavior in two person perception experiments. SA moderated both personality impression ratings of stimulus persons presented singly and person preference choices in a paired comparisons paradigm. In general, self-actualized individuals were found to be more extreme in their responses to social stimuli than were non-self-actualized individuals. Results were discussed in terms of previous attempts to assess the relationship between SA and cognitive processing.     

Three weighting criteria in impression formation

When several items of information are combined to give an overall judgement, it is usually found that some kinds of item are given greater weight than others. This study examines the relations between three criteria which judges may use in deciding how to apportion these weights. The criteria of evaluative direction and extremity have of ten been studied within impression formation, while demonstrations of the influence of ambiguity have produced unclear findings. Simple models of the combination of these three criteria are shown to be inadequate and a more complex account is suggested. A study is reported in which divergence between the criteria of extremity and ambiguity results in a generally greater bias to negative. This effect is related to other studies of the influence of inconsistency, and range adjustment model of the judgement process is extended to take it into account.     

An adding result in impression formation

Ss were presented with a highly polarized piece of information, followed by a same-signed moderately polarized piece of information, and were asked whether the second piece of information led them to like the person describedmore, less, or just the same. The obtained percentage ofadding responses was 65%; that is, most of the responses indicated that Ss impression of the person described became more polarized following addition of moderately polarized information (p <.001). More adding was obtained for negatively than for positively evaluated adjectives (p <.05).     

The adoption of approach versus avoidance goals: The role of goal-relevant resources

The present research investigated whether the adoption of approach versus avoidance goals is affected by goal-relevant resources. When individuals have few goal-relevant resources, they should prefer avoidance goals, whereas when individuals have many goal-relevant resources, they should adopt approach goals. The individual’s outcome expectancy is assumed to mediate this relationship. This hypothesis is supported by the findings of four multi-method studies with student samples. A cross-sectional field study showed a positive relationship between the extent of goal-relevant resources and approach goal adoption. In a longitudinal field study, a high number of resources predicted the increase in personal approach goal adoption over a period of 4 months, controlling for neuroticism. Two experiments showed that the manipulation of resources affected approach versus avoidance task goal adoption, with outcome expectancy mediating the relationship. These findings complement existing findings on dispositional determinants of approach versus avoidance goal adoption.     

How goals affect the organization and use of domain knowledge

Expert specialists organize their knowledge around information related to their goals. In the experiments presented here, the relation between goal use and knowledge organization was investigated by manipulating participants' goals as they learned about a novel domain. Experiment 1 showed that goal use produces biases toward goal-related information in categorization and induction. Experiment 2 revealed that the bias toward goal relatedness is not absolute; participants use their knowledge flexibly, depending on the context of induction. Experiment 3 showed that using information in the absence of a meaningful goal does not produce significant goal-related biases. Altogether, the effects of goal use are evident across a number of tasks and may depend on goal meaningfulness and the coherence it provides to goal-related knowledge structures.     

Similarity to the self influences cortical recruitment during impression formation

Prior work has shown that whether or not someone is similar to the self influences person memory—a type of self-reference effect for others. In this study, we were interested in understanding the neural regions supporting the generation of impressions and subsequent memory for targets who vary in similarity to the self. Participants underwent fMRI scanning while forming positive or negative impressions of face–behavior pairs. We tested participants’ memory for their generated impressions and then back-sorted the impression trials (encoding) into different levels of self-similarity (high, medium, low) using a self-similarity posttest that came after recognition. Extending prior behavioral work, our data confirmed our hypothesis that memory would be highest for self-similar others and lowest for self-dissimilar others. Dorsal anterior cingulate cortex (dACC) activity increased with self-similarity (high > medium > low) to targets, regardless of later memory for them. An analysis of regions supporting impression memory revealed a double dissociation within medial temporal lobe regions: for similar others, amygdala recruitment supported memory, whereas for dissimilar others, hippocampal activation supported memory. These results suggest that self-similarity influences evaluation and memory for targets but also affects the underlying neural resources engaged when thinking about others who vary in self-similarity.     

How visual spatial attention alters perception

Visual attention is essential for visual perception. Spatial attention allows us to grant priority in processing and selectively process information at a given location. In this paper, I explain how two kinds of spatial attention: covert (allocated to the target location, without accompanying eye movements) and presaccadic (allocated to the location of the upcoming saccade’s target) affect performance and alter appearance. First, I highlight some behavioral and neuroimaging research on covert attention, which alters performance and appearance in many basic visual tasks. Second, I review studies showing that presaccadic attention improves performance and alters appearance at the saccade target location. Further, these modulations change the processing of feature information automatically, even when it is detrimental to the task at hand. We propose that saccade preparation may support transsaccadic integration. Systematically investigating the common and differential characteristics of covert attention and presaccadic attention will continue to further our understanding of the pervasive selective processing of information, which enables us to make sense of our complex visual world.     

Further evidence for meaning change in impression formation

Hamilton and Zanna (Journal of Personality and Social Psychology, 1974, 29, 649–654) demonstrated that the meaning of an attribute as rated on connotatively related scales changed as a function of context desirability. This finding was viewed as supporting a meaning change interpretation of context effects in impression formation. Kaplan (Memory and Cognition, 1975, 3, 375–380, Exp. 1) found that similar changes also occurred on scales unrelated in meaning to the test attribute and argued that changes on both kinds of scales were due to halo effects produced by the contexts. Controlling for possible scaling artifacts, the first experiment reported here showed that substantially greater changes occurred on related than on unrelated scales. Kaplan (1975, Exp. 2) also found that the magnitude of context-induced differences in judgments of trait likability was not increased by creating contexts denotatively related to the test attributes. Adding measures of connotative meaning, the second experiment in this paper showed that substantially greater context-induced changes did occur on related meaning scales and, in contrast to Kaplan, on trait likability for the denotatively related contexts. The results of each experiment are consistent with a meaning change position but would not be expected on the basis of the halo effects model.     

Displaced aggression: Frustration or impression management

An experiment is reported testing an impression management interpretation of previous research demonstrating displaced aggression effects. It was found that superior performance by a confederate and not annoyance was related to increased use of shocks by subjects. Path analyses provided additional support for an impression management interpretation of these results, and disconfirmed frustration-aggression theory.     

Domain specific effects of central traits in impression formation

In a procedure similar to that used in Asch's classic studies in 1946, 125 college students (54 men and 71 women, Mage=20.9 yr., SD=4.8) rated their impression of a hypothetical man or woman who was described by seven stimulus traits. This list included one of four central traits which appeared in the middle of the list: warm, cold, serious, or foolish. The dependent measures were factor scores derived from participants' ratings of 20 traits on social desirability and intellectual desirability. As hypothesized, warm and cold, prototypes of social desirability and undesirability, were associated with judgments of social but not intellectual desirability, and serious and foolish, prototypes of intellectual desirability and undesirability, were associated with judgments of intellectual but not social desirability. In addition, there was evidence of a subtle sex bias: ratings of "foolish" women were higher on social desirability than ratings of "foolish" men.
