Retrieval selectivity in memory-based impression judgments.

Judgments about others are often based on memory for information about the persons being judged. Three studies with a total of 92 undergraduates are reported that used decision time to determine what information Ss selectively recall when they make memory-based person judgments. Each study employed a sequential judgment paradigm in which an S first made an impression judgment about a person on one dimension while stimulus information was continuously available. Immediately therafter, the S made a 2nd judgment about the same person on a different dimension without the stimulus information being available. It is concluded that Ss' memory-based judgments were based on memory for their 1st impression judgments combined with a selective memory search for negative stimulus information.

Use of exemplars and abstractions in trait judgments: A model of trait knowledge about the self and others.

According to pure exemplar models, trait judgments about the self and others are accomplished by retrieving from memory trait-exemplifying behaviors and computing the similarity between the trait and the exemplars retrieved. By contrast, pure abstraction models argue that trait judgments are made by directly accessing abstract, summary knowledge of the person's traits. In a series of 4 studies, the role of behavioral exemplars and abstract trait knowledge in trait judgments about others and about the self was examined. The findings show that both types of information are used to make trait judgments but that the relative importance of each type is determined by the amount of trait-exemplifying behavioral experience one has with the person being judged.

The relationship between memory and judgment depends on whether the judgment task is memory-based or on-line.

Five alternative information processing models that relate memory for evidence to judgments based on the evidence are identified in the current social cognition literature: independent processing, availability, biased retrieval, biased encoding, and incongruity-biased encoding. A distinction between 2 types of judgment tasks, memory-based vs online, is introduced and is related to the 5 process models. In 3 experiments, using memory-based tasks where the availability model described Ss' thinking, direct correlations between memory and judgment measures were obtained. In a 4th experiment, using online tasks where any of the remaining 4 process models may apply, prediction of the memory–judgment relationship was equivocal but usually followed the independence model prediction of zero correlation. It is concluded that memory and judgment will be directly related when the judgment was based directly on the retrieval of evidence information in memory-based judgment tasks.

Aging and impression formation: the impact of processing skills and goals

Two studies assessed age differences in representations and judgments about people. Our specific interest was in examining how presumed age-related changes in processing efficiency and motivation affected performance in an impression formation task. Consistent with age-related declines in processing efficiency, we found that increasing age was associated with: (a) no change in the processing of evaluative information; (b) less use of specific traits to organize impressions; (c) poorer memory for behavioral information, especially when it contradicted expectations; and (d) less systematic relationships between memory and judgments. We also found, however, that more meaningful task goals and a focus on individual behaviors resulted in reduced age differences in the nature of representations about the target person.     

Exemplar-based model of social judgment.

As an alternative to algebraic and schematic models of social judgment, a new exemplar-based model holds that representations of specific individuals influence judgments about persons and groups. (1) As the perceiver encounters or thinks about an individual, a representation of that exemplar as interpreted by the perceiver is stored in memory. (2) When a target person is encountered later, known attributes of similar exemplars from memory influence judgments about the target. Similarity is modulated by the perceiver's attention to stimulus dimensions. (3) Social and motivational factors, including perceiver self-schemata, social context, and in-group/out-group dynamics, influence social judgment by affecting perceivers' attention to dimensions. Computer simulations show how the model accounts for social influences on exemplar access and use, and therefore, on the content of social judgments.

Processing objective and question order effects on the causal relation between memory and judgment in performance appraisal: The tip of the iceberg.

This study extends the research on information processing in performance appraisal judgments. A critical aspect of this research is the relation between memory and judgment processes. Performance appraisal researchers have traditionally assumed that performance judgments are based on memory for specific behaviors; implicit in this assumption is the idea that as memory for specific behaviors improves, judgmental accuracy should also improve. The authors elaborate the circumstances under which performance ratings are more or less likely to be based on previously formed judgments as opposed to memory for specific information. Results indicate that the causal relation between memory and judgment is driven by contextual factors at the time ratings are required as well as at the time information is encoded.

Human cognition in its social context.

Presents a model of how the human cognitive system operates in its natural social context. The model focuses on both input and output variables that have been ignored in the development of most other cognitive theories. On the input end, the model emphasizes the role of prior knowledge and the goal-directed nature of social information processing. On the output end, the model emphasizes various types of social judgments and affective reactions, as well as memory and behavioral decision making. The model is designed to provide a general conceptual framework for integrating much of contemporary social cognition research. As such, it is consistent with, and occasionally subsumes, more molecular theories of specific social phenomena. An indication of the model's applicability to cognitive heuristics, representation of self, and the role of affect in information processing is included. Predictions of the model (e.g., the effects of information on both recall and judgments when the information is processed for different purposes) and the empirical evidence bearing on them are discussed.

Organizational and retrieval processes in person memory: An examination of processing objectives, presentation format, and the possible role of self-generated retrieval cues.

Examined memory for behavioral information under conditions in which the number of target persons and the number of behaviors pertaining to each target person were simultaneously varied. 256 undergraduates recalled more of the behavioral information when given a general impression set than when given a memory set, when the information was presented blocked by person than when it was presented randomly, and when they were tested immediately rather than after a delay. Impression-set Ss recalled more behaviors per person than memory-set Ss when the information was presented in a blocked format. However, they recalled more individual target persons and more behaviors per person when the information was presented in a random format. Results suggest that the specific nature of processing objectives and the constraints imposed by presentation format need to be considered carefully in developing future theoretical models of person memory. The role of self-generated retrieval cues and the possibility that there are 2 conceptually distinct types of retrieval are discussed.

Structure of gender stereotypes: Interrelationships among components and gender label.

Assessed the extent to which gender label and various types of component information influenced the judgments made by 458 undergraduates in 3 experiments regarding the existence of other gender-related characteristics not specifically implied by the provided information. In Exp I, 42 male and 65 female undergraduates were given gender and role information about a person and asked to estimate the probability that the person had a number of other characteristics or engaged in a number of other behaviors. In Exp II, 84 male and 92 female Ss followed the previous procedure but were given traits rather than roles of the person. Results show that gender stereotypes consisted of a number of separate components. In Exp III, each of 4 gender stereotype components was presented in a within-Ss design, and 83 male and 88 female Ss made judgments about each component. Results show that information about one stereotype component can implicate other components; specific component information may outweigh gender identification; and components differ in their ability to implicate other components of gender stereotypes, with physical appearance playing a dominant role.

Judgmental biases resulting from differing availabilities of arguments.

Hypothesized that information which is disproportionately available in memory will have a correspondingly disproportionate impact on evaluative judgments. In a mock jury decision, the availability of selected information in memory was varied according to the relative vividness of the evidence (prosecution evidence more vivid or defense evidence more vivid) and the favorableness of the defendant ("good guy" or "bad guy"). 54 university students judged the defendant's guilt immediately and after 48 hrs; in addition, they recalled the evidence after the 48-hr interval. Ss recalled more vivid evidence and more evidence that disagreed with the defendant's favorableness. Their judgments of apparent guilt paralleled their differential recall of the prosecution and defense evidence. These availability differences occurred only after the retention interval and did not affect judgments given immediately after reading the arguments. Results support a model in which judgments are based on the availability and the diagnosticity of the information. (26 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Person stereotypes and memory for people.

Tested the proposal by M. Snyder and S. W. Uranowitz (see record 1980-05464-001) that there exists a memory-priming mechanism by which information about a person that is normally unavailable in episodic memory is made available by the activation of a person stereotype that subsumes that information. In 2 experiments 128 college students read a biography of Betty K, who was later labeled as either a heterosexual or a lesbian before Ss took a recognition memory test. A signal-detection model was used to assess the effects of labeling on response bias as well as on the amount of information available in memory. The memory availability hypothesis predicted that Ss primed with a lesbian label for Betty K would have more availability in memory of lesbian information, and Ss primed with a heterosexual label would remember more heterosexual material. Neither experiment produced any improved recognition memory for biographic information due to activation of a sexual stereotype. Both experiments found a response bias (guessing) acting in the direction of the label S received. (22 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Recognition memory ROCs for item and associative information: the contribution of recollection and familiarity

Receiver-operating characteristics (ROCs) were examined in three recognition memory experiments. ROCs for item information (i.e., was this word presented?) were found to be curvilinear. However, ROCs for associative information (i.e., were these two words presented together?) were found to be linear. The results are in agreement with the predictions of a dual-process model that assumes that recognition judgments are based on familiarity and recollection. Familiarity reflects the assessment of a continuous strength dimension and is well described as a signal detection process, whereas recollection reflects the retrieval of qualitative information about the study episode and behaves like a discrete threshold process. The results showed that memory judgments about items relied on a combination of recollection and familiarity, but that judgments about associations relied primarily on recollection. Further examination of the associative ROCs suggested that subjects were able to recollect that old pairs of items were in the study list, and, under some conditions, that new pairs were not in the study list.     

On the process relationship between person and situation judgments in attribution.

Ss were timed in 3 experiments as they answered 2 consecutive questions about stimulus sentences. The measure of interest was the extent to which answering the 1st question speeded-up answering the 2nd. The order of questions about person and situation influences on behavior was manipulated. Results indicated that the person judgment facilitated the situation judgment significantly more than the situation judgment facilitated the person judgment. The pattern of facilitation was reversed when Ss answered questions about themselves. Results are consistent with a model of concurrent resource allocation to person and situation information in conditions where the primary judgment task involves salient information. However, they are not consistent with a unidimensional or automatic view of person and situation judgments. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
