The letter of recommendation effect in informant ratings of personality.

In most studies using informant reports of personality, the informants are recruited by the targets. Such informants may tend to like the targets and thus portray them in specific ways (e.g., too positively). Study 1 (N = 403) demonstrated the necessity to distinguish between “liking” and “knowing” in studying the relationships between informants and targets. Informants who liked their targets better described them more positively (i.e., as being more extraverted, agreeable, open, conscientious, and less neurotic). The association between personality ratings and liking was moderated by item evaluativeness. Liked targets were also described as being more similar to each other (range restriction), which would lower correlations of informant ratings of personality with external variables. Study 2 (N = 90) used a within-subjects design to disentangle actual personality differences between targets (substance) from the informants’ specific views on the targets (style). Ninety informants were asked to nominate targets they did not like. These targets then nominated informants of their own choice. Target-nominated informants liked the targets very much and described the targets’ personalities very positively and in ways that were highly redundant with the average target’s self-rating. There was evidence that lower liking may be associated with better accuracy. Higher subjective levels of knowing were not associated with better interrater agreement but with a greater willingness to describe targets negatively. Implications for the field of recruiting are discussed. Where possible, the choice of informants and referees should be made independent of the targets’ preferences.

Missing the trees for the forest: A construal level account of the illusion of explanatory depth.

An illusion of explanatory depth (IOED) occurs when people believe they understand a concept more deeply than they actually do. To date, IOEDs have been identified only in mechanical and natural domains, occluding why they occur and suggesting that their implications are quite limited. Six studies illustrated that IOEDs occur because people adopt an inappropriately abstract construal style when they assess how well they understand concrete concepts. As this mechanism predicts, participants who naturally adopted concrete construal styles (Study 1) or were induced to adopt a concrete construal style (Studies 2–4 and 6), experienced diminished IOEDs. Two additional studies documented a novel IOED in the social psychological domain of electoral voting (Studies 5 and 6), demonstrating the generality of the construal mechanism, the authors also extended the presumed boundary conditions of the effect beyond mechanical and natural domains. These findings suggest a novel factor that might contribute to such diverse social-cognitive shortcomings as stereotyping, egocentrism, and the planning fallacy, where people adopt abstract representations of concepts that should be represented concretely.

Social evaluation and the empathy–altruism hypothesis.

Tested the claim of R. L. Archer et al (see record 1982-05783-001) that empathy leads to increased helping only under socially evaluative circumstances. In Exp I, 22 female undergraduates were led to believe that no one (including the person in need) would ever know if they declined to help. In this situation, which was designed to be devoid of the potential for negative social evaluation for not helping, there was still a positive relationship between self-reported empathic emotion and offering help. In Exp II, empathy (low vs high) and social evaluation (low vs high) were manipulated with 32 Ss. Once again there was a positive relationship between empathy and offering help when the potential for social evaluation was low as well as high. Results of both studies suggest that the motivation to help evoked by empathy is not egoistic motivation to avoid negative social evaluation. Instead, the observed pattern was what would be expected if empathy evokes altruistic motivation to reduce the victim's need.

Adolescent egocentrism and formal operations: Tests of a theoretical assumption.

The theoretical relation between adolescent egocentrism and formal operations was addressed in 2 studies. In Study 1, this relation was assessed with the Adolescent Egocentrism Scale (AES; R. Enright et al, see PA, Vols 63:5127 and 65:10218) and a battery of formal reasoning tasks administered to 183 6th-, 8th-, 10th-, and 12th-graders. The results reveal only significant negative or nonsignificant correlations between the measures in early adolescence. There was also no evidence of significant developmental covariation from early to middle adolescence. The validation effort was extended in Study 2 to include 2 measures of adolescent egocentrism (AES and the Imaginary Audience Scale [IAS; D. Elkind and R. Bowen, see PA, Vol 62:5769]) and a 2nd battery of formal operations problems. These measures were administered to 117 7th-, 9th-, and 11th-graders and to 56 undergraduates. There was once again no evidence of significant developmental covariation among the measures. The correlations between the AES and IAS were modest, reflecting differences in the nature and content of the measures. It is concluded that little support exists in this study or in the literature for the crucial theoretical assumption of adolescent egocentrism.

Development of Boundary Structures for Complex-Shaped Buildings

Over the past few years, the field of architecture has witnessed revolutionary changes in design. The recent completions of Frank O. Gehry’s projects brought unprecedented attention to complex-shaped, nonconventional design. In following these latest trends, the author has been drawn to the issue concerning the structural systems currently being adopted in realizing these complicated designs. It is perhaps inevitable that the traditional structural systems, comprised of structural elements suitable for use in conventional linear shapes, face tremendous challenges and limitations in building such complicated designs. In this context, this research consists of proposing a new alternative by employing “boundary structures with continuously changing curvature,” which follow the complex-curved envelope surface, as well as fabricating an experimental model made of polymer composite materials with computer-aided design/computer-aided engineering/computer-aided manufacturing technologies. Consequently, the study aims at offering architects unprecedented freedom in design and a new paradigm for realizing their creative ideas.     

Trajectories leading to school-age conduct problems.

The present study applied a semiparametric mixture model to a sample of 284 low-income boys to model developmental trajectories of overt conduct problems from ages 2 to 8. As in research on older children, 4 developmental trajectories were identified: a persistent problem trajectory, a high-level desister trajectory, a moderate-level desister trajectory, and a persistent low trajectory. Follow-up analyses indicated that initially high and low groups were differentiated in early childhood by high child fearlessness and elevated maternal depressive symptomatology. Persistent problem and high desister trajectories were differentiated by high child fearlessness and maternal rejecting parenting. The implications of the results for early intervention research are discussed, with an emphasis on the identification of at-risk parent-child dyads.

Perceived employment barriers and their relation to workforce-entry intent among people with HIV/AIDS.

As treatments have improved health and quality of life for people with HIV/AIDS, many have contemplated workforce reentry. Workforce reentry rarely occurs among people with illness-related disability. The authors mailed a survey that included workforce-entry-related concerns to 1,991 HIV/AIDS clients. Factor analysis extracted 6 areas of concern (benefits loss, work-related health, job skills, discrimination, personal health care, workplace accommodation). Levels of concern generally increased with HIV acuity level and time since last worked. Work-related health concerns predicted consideration of workforce entry, and work-related health concerns and benefits-loss concerns predicted estimated time to return to work. Findings provide quantitative validation of intuitive categories of workforce-entry concerns among people with HIV/AIDS and suggest that concerns may shift with progress toward workforce entry.

Interstate forensic psychology consultations: A call for reform and proposal of a model rule.

Forensic psychology has made important gains in professional recognition and stature in the courts, resulting in increasing demands for mobility of expertise. Current regulations regarding the interjurisdictional temporary forensic practice of psychology, however, are characterized by variability of regulations, ambiguity and inaccessibility, and continuing total barriers. A uniform, well-reasoned policy is needed. A conceptual basis for such a policy is provided by a discussion of licensing rationales and the application of these to forensic practice. Uniformity, public and professional protection, and practicability are identified as fundamental regulatory criteria. A Model Rule Regarding the Temporary Forensic Practice of Psychology is proposed for adoption by state licensing boards on a nationwide basis.
