Utah Virtual Lab: JAVA interactivity for teaching science and statistics on line.

The Utah on-line Virtual Lab is a JAVA program run dynamically off a database. It is embedded in StatCenter (www.psych.utah.edu/learn/statsampler.html), an on-line collection of tools and text for teaching and learning statistics. Instructors author a statistical virtual reality that simulates theories and data in a specific research focus area by defining independent, predictor, and dependent variables and the relations among them. Students work in an on-line virtual environment to discover the principles of this simulated reality: They go to a library, read theoretical overviews and scientific puzzles, and then go to a lab, design a study, collect and analyze data, and write a report. Each student's design and data analysis decisions are computer-graded and recorded in a database; the written research report can be read by the instructor or by other students in peer groups simulating scientific conventions.

Self-observation of social behavior and metaperception.

In 3 experiments (Ns = 68, 72, and 101) the authors tested the hypothesis that the opportunity to observe oneself in social interaction increases the accuracy of metaperception (prediction of others' social judgments of oneself). Small groups were videotaped during a decision-making task, after which group members judged each other's social anxiety. Participants watched either the videotape of their group's interaction or a videotape of another group's interaction. After watching the videotape, participants predicted how they were judged by each member of the group. Results from the 3 experiments confirmed the hypothesis that self-observation increases the accuracy of metaperception. Presumably, self-observation provides objective information about one's behavior, which increases the ability to determine how one is judged by others, assuming self and others share meaning systems.

Reductions in criminality subsequent to group, individual, and family therapy in adolescent residential and day treatment settings.

The complete population of adolescents in a residential and day-treatment program over a 4-year period, 532 youths, served in two studies. Along with residential and day-treatment settings, predictive variables of interest were the number of hours spent in group, individual, and family therapy. A total of 227 adolescents qualified for Study 1 which found a reduction of rates of criminal charges from pre- to posttreatment. Study 1 also found that hours in group therapy explained the most variance in the reduction in rates of criminal charges, followed closely by hours in individual therapy. Hours in family therapy was not a significant predictor. A total of 430 adolescents qualified for Study 2, which found that residential treatment was associated with greater reductions in adult correctional commitments than day treatment. Implications stress the need for further research examining the relationships between therapeutic components of residential treatment and behavioral outcomes.

Interpersonal perception and metaperception in nonoverlapping social groups.

Consensus, self-other agreement, and meta-accuracy were studied within and across nonoverlapping social groups. Thirty-one target persons were judged on the Big Five factors by 9 informants: 3 family members, 3 friends, and 3 coworkers. Although well acquainted within groups, informants were unacquainted between groups. A social relations analysis conducted within each social group showed reliable consensus on the Big Five personality factors. A model specified to estimate the consistency of a target person's effect on perceptions by others across social groups showed weaker agreement across groups. That is, targets were perceived consensually within groups, but these consensual perceptions differed between groups. The data suggest that personality and identity are context specific; however, there was some evidence of agreement in perceptions across groups.

Cross-cultural consensus in personality judgments.

Building on recent research demonstrating consensus and accuracy in interpersonal perception based on minimal information, the present studies examined American and Chinese participants' within- and cross-cultural judgments. In Study 1, the authors used the zero-acquaintance paradigm in the People's Republic of China and found consensus on all personality dimensions. In Study 2, Chinese and American participants judged each other on the basis of photographs, and consensus was found among Americans' judgments of Chinese and Chinese participants' judgments of Americans. Further, by correlating target effects based on within-culture zero-acquaintance judgments and cross-cultural photographic judgments, the authors found agreement in the judgments of individuals by members of their own culture and the other culture for both Chinese and Americans.

Effects of communication, information overlap, and behavioral consistency on consensus in social perception.

Three experiments (N = 69, 162, and 201, respectively) were conducted to test the mathematically derived predictions of the Weighted Average Model (D. A. Kenny, 1991) of consensus in interpersonal perception. Study 1 estimated the effect of perceiver communication. Study 2 estimated the effects of communication and stimulus overlap, and Study 3 estimated the effects of communication, overlap, and target consistency on consensus. The strongest consensus was found when perceivers communicated about highly overlapping information about targets who were cross-situationally consistent. Conversely, the lowest level of consensus was observed when perceivers did not communicate and had nonoverlapping information about targets who were cross-situationally inconsistent. Both stimulus variables (overlap and consistency) and an interpersonal variable (communication) affected consensus as predicted by the Weighted Average Model.

Interpersonal perception of the AIDS risk potential of persons of the opposite sex.

Individuals engage in high rates of AIDS risk behavior, despite awareness that infection is preventable, and use biased decision rules for determining the AIDS risk potential of their own and others' behavior. In this laboratory study, 32 male and 32 female university students made judgments of the AIDS risk potential of persons of the opposite sex following exposure to explicit information regarding AIDS-related attitudes and behavior in a discussion group. A social relations analysis showed that judgments of AIDS risk potential were determined by perceiver-based assimilation that was stronger than target-based consensus for both men and women. Further, perceptions of others were related to self-perception. However, the consensus that was observed showed moderate accuracy. Implications for AIDS prevention are discussed.

Agreement and accuracy in children's interpersonal perceptions: a social relations analysis.

Agreement and accuracy in children's interpersonal perceptions during middle childhood were studied in the school environment. Sociocultural and ecological theories led to the prediction that, in middle childhood, peers' interpersonal perceptions would show high levels of agreement with those of teachers and would be accurate. A social relations analysis of data from a 3-year, cross-sequential study revealed that throughout middle childhood, peer perceptions of cognitive ability, observable behavior and characteristics, popularity, and affect correlated reliably with teacher perceptions. In addition, peer and teacher perceptions of targets' cognitive ability correlated with standardized test scores. Self-other agreement lagged behind teacher-peer agreement. The conceptual and statistical advantages of the social relations analysis of children's interpersonal perceptions were also considered.

Changing AIDS risk behavior: effects of an intervention emphasizing AIDS risk reduction information, motivation, and behavioral skills in a college student population.

This research used the Information-Motivation-Behavioral Skills (IMB) model of AIDS risk behavior change (J. D. Fisher & Fisher, 1992a) to reduce AIDS risk behavior in a college student population. College students received an IMB model-based intervention that addressed AIDS risk reduction information, motivation, and behavioral skills deficits that had been empirically identified in this population, or were assigned to a no-treatment control condition. At a 1-month follow-up, results confirmed that the intervention resulted in increases in AIDS risk reduction information, motivation, and behavioral skills, as well as significant increases in condom accessibility, safer sex negotiations, and condom use during sexual intercourse. At a long-term follow-up, the intervention again resulted in significant increases in AIDS preventive behaviors.

Empirical tests of an information-motivation-behavioral skills model of AIDS-preventive behavior with gay men and heterosexual university students.

This article contains empirical tests of the information-motivation-behavioral skills (IMB) model of AIDS-preventive behavior (J.D. Fisher & Fisher, 1992; W.A. Fisher & Fisher, 1993a), which has been designed to understand and predict the practice of AIDS-preventive acts. The IMB model holds that AIDS-preventive behavior is a function of individuals' information about AIDS prevention, motivation to engage in AIDS prevention, and behavioral skills for performing the specific acts involved in prevention. The model further assumes that AIDS-prevention information and motivation generally work through AIDS-prevention behavioral skills to influence the initiation and maintenance of AIDS-preventive behavior. Supportive tests of the model, using structural equation modeling techniques, are reported with populations of gay male affinity group members (n = 91) and heterosexual university students (n = 174).

Consensus in interpersonal perception: acquaintance and the big five.

Consensus refers to the extent to which judges agree in their ratings of a common target. Consensus has been an important area of research in social and personality psychology. In this article, generalizability theory is used to develop a percentage of total variance measure of consensus. This measure is used to review the level of consensus across 32 studies by considering the role of acquaintance level and trait dimension. The review indicates that consensus correlations ranged from zero to about .3, with higher levels of consensus for ratings of Extraversion. The studies do not provide evidence that consensus increases with increasing acquaintance, a counterintuitive result that can be accounted for by a theoretical model (D.A. Kenny, 1991, in press). Problems in the interpretation of longitudinal research are reviewed.

Mitral valve prolapse and neuroticism in chest pain patients with normal and diseased coronary arteries.

Patients with chest pain and normal coronary arteries (NCA) score higher on measures of neuroticism than patients with coronary artery disease (CAD). This relationship, coupled with findings linking mitral valve prolapse (MVP) and anxiety disorders, led us to examine prospectively the possibility that a greater incidence of MVP among NCA patients accounts for their elevated neuroticism scores. One-hundred-forty-four patients completed psychological tests and a structured interview prior to cardiac catheterization. Forty-one of the 144 patients (28%) had normal coronary arteries. Within the NCA group 29 percent had MVP; within the CAD group only 13 percent had MVP. Despite the significant difference between NCA and CAD groups on measures of neuroticism, there were no differences as a function of MVP status, nor was there an interaction of MVP and coronary arterial status. These findings support the case for an association between NCA and neuroticism independent of the presence or absence of MVP.

Interpersonal perception in a social context.

Interpersonal perception among well-acquainted individuals in a social context was studied. High acquaintance was expected to provide perceivers with a large sample of target behaviors across situations. In turn, memory for acquaintances should be organized by social group and personality characteristics, as predicted by the social context-personality index theory. Differentiation of the target's traits in memory should produce a target effect on perception that is stronger than the perceiver effect. Furthermore, evidence for accuracy, meta-accuracy, independence of self- and other-perception, and reciprocity of affect were anticipated. A social relations analysis of data from a multiple-interaction, reciprocal design was used to study these phenomena. At the individual level, analyses indicated that perceptions of targets were determined primarily by target characteristics and secondarily by perceiver construction of the judgment. Also, perceivers judged targets as targets judged themselves, and targets knew in general how perceivers viewed them. Self- and other-perceptions were largely independent. Surprisingly, we did not observe dyadic meta-accuracy.

Consensus in personality judgments at zero acquaintance.

This research focused on the target effect on a perceiver's judgments of personality when the perceiver and the target are unacquainted. The perceiver was given no opportunity to interact with the target, a condition we refer to as zero acquaintance. We reasoned that in order to make personality judgments, perceivers would use the information available to them (physical appearance). Consensus in personality judgments would result, then, from shared stereotypes about particular physical appearance characteristics. Results from three separate studies with 259 subjects supported this hypothesis. On two of the five dimensions (extraversion and conscientiousness) on which subjects rated each other, a significant proportion of variance was due to the stimulus target. Consensus on judgments of extraversion appears to have been largely mediated by judgments of physical attractiveness. Across the three studies there was also evidence that the consensus in judgments on these two dimensions had some validity, in that they correlated with self-judgments on those two dimensions.

The relationship between therapist-client interpersonal compatibility, sex of therapist, and therapeutic outcome.

Explored the relationship between therapist-client interpersonal compatibility, sex of therapist, and psychotherapeutic outcome. The research sample consisted of 48 therapist-client dyads. The therapists were all graduate students enrolled in an individual therapy practicum, while the client sample was composed of 48 undergraduate female (mean age 19.3 years). The interpersonal compatibility of the dyads was determined from the FIRO-B results for each of the members' using a modification of Schutz's (1966) original mathematical schema. Therapy outcome was determined from pretherapy and posttherapy testing with the Tennessee Self Concept Scale and Mooney Problem Check List. A 3 X 2 research design with one concomitant variable (pretest) was used and data were analyzed using an analysis of covariance procedure. Results suggested that among this sample the sex of therapist did not have a significant differential effect. There was also a consistent lack of interaction effects between dyadic compatibility and sex of therapist. However, significant differences in therapeutic outcome across the levels of compatibility were observed.
