Cognitive processes in person perception: Retrieval of personality trait and behavioral information

The processes people use to retrieve information about another person's behavior and personality were investigated. Subjects viewed different lengths of segments from videotaped sequences of actors' behaviors. The subjects' reaction times to questions about the actors' behaviors and about personality traits were both an increasing function of the duration of the segment about which the questions were asked. These data were taken as an indication that people do, in general, carefully examine the contents of their memories in order to respond to questions about another person. In particular, an exhaustive serial search model was supported. Additional data and analyses demonstrated that relatively abstract trait terms usually were answered on the basis of the exhaustive search, while relatively specific trait terms were not. A two-stage process model was proposed to explain the differences in the results for the two types of trait terms.     

Perception and behavior as compositions of ideals

This essay is a discussion of whether or not there are units out of which human perception, cognition, and action are constructed. It proposes that while these human activities are indeed generated from component aspects, we cannot talk of these aspects as “units” or as being directly inserted into these activities. Instead, we must describe them as “ideals” which enter into composition with one another in particular situations to generate a situationally specific structure which serves both to describe and control the situation in its particular aspects. In the process of composition, the standard form of the ideal is transformed so that the ideal may appear in a different form in each different composition. Furthermore, superficially similar compositions can arise from different combinations of ideals. These notions are shown to have the potential of unifying our accounts of a wide variety of psychological phenomena. An argument is also made that operational definition of ideals is impossible and that interpretive methods of investigation are justified.     

The effects of communication,resource feedback,and identifiability on behavior in a simulated commons

This study examined the effects of communication, feedback, and identifiability on behavior in a simulated commons. To do this, 64 mixed-sex groups of four introductory psychology students participated in a commons dilemma simulation for 50 trials or until the group exhausted the commons pool. Half of the groups played under a free communication condition, while the other half were prohibited from communicating. Half of the groups in both communication conditions received visual feedback about the amount of the commons' resource (money) which remained after each trial while the other half received no feedback. Finally, half of the groups in each of these four conditions were made highly identifiable by the use of the name tags and feedback about the choices of each player. The remaining groups were assigned to a low identifiability condition in which no name tags were used, no feedback given and group members were separated by wooden dividers to prevent visual contact. Results showed that groups having the opportunity for resource feedback or for communication achieved greater total money harvests and maintained the commons for a greater number of trials than groups having neither. As expected, the largest totals and longest commons maintenance were achieved by groups having both. Identifiability had no influence on the length of commons maintenance except when there was neither resource feedback nor communication opportunities. When both were unavailable, groups in the high identifiability condition harvested more money and maintained the commons longer.     

Memories of Morocco: The influence of age,schooling, and environment on memory

To what extent are models of memory general, in that they may be applied to children or to other cultural groups? In an attempt to answer this question, two experiments were undertaken in Morocco to investigate various cultural and experiential antecedents to memory development. A total of 384 children and young adults, ranging in age from 6 to 22 years, were tested in a design that contrasted schooled and nonschooled children in urban and rural environments. Three additional groups of subjects—Koranic students, Moroccan rug sellers, and University of Michigan students—were also studied because it was hypothesized that each might have particular “culture-specific” memory skills as a function of previous experience.A serial short-term recall task was used in Experiment I. Results showed that the recency effect or short-term store was generally invariant with age or experience. Control processes appeared to be a function of age, but only when coupled with schooling, and, to a lesser extent, urban environment. In Experiment II, a continuous recognition memory task was given with black and white photographs of Oriental rugs as stimuli. Forgetting rates were generally invariant with age and experience, while the acquisition parameter seemed to vary as a function of specific cultural experiences. Data from the three additional groups were useful in supporting the hypothesis of culture-specific memory skills.From Experiments I and II, and previous research, it was hypothesized that structural features of memory (e.g., short-term store and invariant forgetting rates) may be universal, while control processes or mnemonics in memory are probably culture-specific, or a function of a variety of experiential and cultural factors that surround the growing child.     

On the formation of personal space and self-boundary structures in early human development: The case of infant stranger reactivity

Personal space and self-boundary are, respectively, sociological and intra-psychological concepts that refer to a complex of behavioral and subjective events between and within individuals. While there are large bodies of literature concerned with each of these concepts, literature that cuts across many disciplines of study, there has never been an integration of these concepts around specific human developmental issues. The present article focuses upon human infancy as a period in which both personal space and self-boundary phenomena can be observed. Developmental links between personal space and self-boundary phenomena in infancy and adulthood are outlined and discussed.     

The role of esteem and coping in response to a threat communication

Two experiments examined the relations among self-esteem, perceived competency to cope, and actual coping behaviors following a threat communication. Leventhal's “parallel response model” (in Advances in experimental social psychology, L. Berkowitz (Ed.), New York: Academic Press, 1970, Vol. 5) predicts that low-esteem subjects will show deficits in both competency and coping behaviors. Experiment 1 manipulated threat level of a tetanus communication. Low-esteem subjects showed coping deficits on measures of free associations, free recall, fatalism, and coping. Threat groups differed only on fear and danger measures. Experiment 2 manipulated the fear level of an antismoking film and used false feedback to alter perceived competency. Positive feedback increased perceived competency to quit smoking among low-esteem subjects only. Without feedback, low-esteem subjects reduced smoking less than high-esteem subjects; positive feedback reversed the pattern. The discussion argued that, consistent with Leventhal's model, the low-esteem coping deficit has two independent causes: (1) excessive concern with fear, and (2) inadequate perceived competency.     

Children's relative number judgments: One-to-one correspondence,recognition of noncorrespondence,and the influence of cue conflict

Although one-to-one correspondence can be seen as a component of successful counting, number conservation, and relative number judgments, there is evidence of considerable discrepancies between children's competencies in these different tasks. Concerning relative number judgments there are strikingly different claims concerning the ability of young children to make one-to-one correspondence-based judgments. In part these discrepancies reflect differences in criteria. Four experiments are reported in which 5-year-olds' relative number judgments of small and large number displays with and without perceptual aids were studied. Children were found to respond to local rather than global density differences and to benefit from the provision of perceptual aids on both small and large number displays with one exception, namely, large number displays where the longer row is less numerous.     

Behavioral similarity,confederate strategy,and sex composition of dyad as determinants of interpersonal judgments and behavior in the prisoner's dilemma game

The study was designed to test three distinct theoretical models relating player's attitudes toward a confederate in the prisoner's dilemma game: a reinforcing outcome model, a cultural norm model, and a social comparison model. A secondary concern of the study was to determine if player's sex, confederate's sex, and the confederate's strategy interactively influence player's choice behavior. Forty-eight male and forty-eight female subjects played 100 trials of the prisoner's dilemma game with a confederate who played either a 74% cooperative or 74% competitive predetermined strategy and then filled out the Interpersonal Judgment Scale rating the confederate. Behaviorally similar confederates received more positive evaluations than dissimilar confederates supporting the social comparison hypothesis. Further, the strategy of the confederate did not influence choice behavior in mixed-sex dyads, suggesting that sex roles may inhibit behaviorally based male-female interaction. The generality of previous gaming research which has dealt almost exclusively with same-sex dyads is called into question.     

Stimulus intrusion on fixed-interval responding in the rat: The effects of electric shock intensity,temporal location,and response contingency

After a scalloped lever-press response pattern had developed under a fixed-interval food reinforcement schedule, a 15-sec electric shock was intruded for different groups of rats in the first, second, third, or fourth quarter of each inter-reinforcement interval. Shock intensity was systematically increased for individual rats over 70 sessions, from 0.05 to 1.6 mA. Additional between-groups comparisons involved response-dependent versus clock-dependent fixed-interval schedules, and response-dependent versus response-independent electric shock intrusion. Response rates within each fixed interval prior to, during, and following electric shock intrusion showed regular and reproducible increases and decreases under systematic application of the experimental variables. These results provide further evidence that the functions of a stimulus are determined in part by the parameters of intensity, response contingency, and temporal location with respect to reinforcement.     

The role of self-esteem and locus of control in the differential prediction of performance,program satisfaction,and life satisfaction in an educational organization

The present research was an attempt to examine the role of task-specific self-esteem Korman, 1966, Korman, 1976 and locus of control (Rotter, 1966) in the differential prediction of academic performance, program satisfaction, and personal life satisfaction. Based on earlier research and theory in this area, it was predicted that (1) high task-specific self-esteem individuals would perform better, would be more satisfied with their program of studies and their personal lives compared to low task-specific self-esteem individuals, and (2) individuals with an internal locus of control would also perform better, would be more satisfied with their program of studies and their personal lives compared to individuals with an external locus of control. These hypotheses found strong empirical support in the study. The findings are interpreted as being strongly supportive of Korman's theory on the role of task specific esteem and Rotter's theory on the concept of locus of control in the prediction of certain select organizational outcomes.
