Prediction of Students' Evaluations from Brief Instances of Professors' Nonverbal Behavior in Defined Instructional Situations

This study examined the power of judges' ratings of professors' nonverbal (NV) classroom behavior in content-free brief instances (nine seconds) to predict actual end-of-course students' ratings of teaching (SRT). Professors in 67 courses were videotaped in 4 instructional situations: First class session; Lecturing; Interacting with students; and Talking about the course. The overall finding was that thin slices of professors' content-free NV behavior could indeed predict SRT, but different patterns were found for defined instructional situations. Positive judgments of brief instances of NV lecturing behavior predicted positive post-course SRT components pertaining to the instructor. Positive judgments of NV behavior while interacting with students were negatively related to favorable SRTs. This counter-intuitive finding was tentatively explained by the fact that SRTs were negatively related to course difficulty, and professors presumably might have made greater efforts in their interaction with students in difficult courses, but these courses received lower ratings anyway. Micro-analyses of 44 molecular variables illuminated the NV profile of effective lecturing, and showed distinctions between NV profiles of effective professors and effective TV interviewers from a previous study. Social-educational implications of the findings for the SRT literature and for the NV literature were discussed.

Science and ethics in conducting, analyzing, and reporting psychological research

The relationship between scientific quality and ethical quality is considered for three aspects of the research process: conduct of the research, data analysis, and reporting of results. In the area of conducting research, issues discussed involve design, recruitment, causism, scientific quality, and costs and utilities. The discussion of data analysis considers data dropping, data exploitation, and meta-analysis. Issues regarding reporting of results include misrepresentation of findings, misrepresentation of credit, and failure to report results as a result of self censoring or external censoring.     

Complexities in Cancer Risk Counseling: Presentation of Three Cases

Complexities abound in the identification and management of families at increased risk for inherited forms of cancer. One of the ways to learn as a profession how best to provide cancer risk counseling (CRC) is to share counseling experiences. Such cases can provide insight into the issues raised by families and ways in which genetic counselors have handled complex situations. Here we describe three CRC cases initially presented at the 1995 American College of Medical Genetics meeting. The first case involves balancing the importance of informing a family of the presence of an inherited cancer syndrome with the family's right not to know. The second case illustrates the difficulties in assisting an individual to make medical management decisions in the face of uncertain risk information. The third case describes the complex interactions with a woman before and after her decision to have prophylactic surgery.

The effects of covert and overt modeling on assertive behavior

Three modeling therapy formats (overt modeling with a standard hierarchy of situations. covert modeling with the standard hierarchy, and covert modeling with a self-tailored hierarchy) were compared to assess their relative efficacy in developing assertive skills. Half the subjects in each treatment condition received or did not receive generalization training. Significant within-group improvement was indicated on four self-report measures. Overall, the results suggest that covert modeling was as effective as overt modeling or covert modeling plus self-tailoring for instating assertion among nonassertive college women.     

Concept attainment, transfer, and retention through observation and rule-provision

The effects of observing a model and of providing a response rule on the learning, transfer, and retention of a dial-reading, numerical concept were studied in 144 third graders. Different Es conducted the immediate learning procedures versus the measurements of retention. No extrinsic reinforcers were promised or dispensed. The children profited both from modeling and from rule-provision, with the strongest learning, transfer, and retention displayed by the group that watched the model and also received the rule summary. Sequence of presenting the sets of retention stimuli (including a series of novel generalization items not previously encountered) did not influence the strength of concept retention 6 weeks after training.
