The combination of an unpolarized multimode laser with standard dielectric beam control devices can give rise to large intensity fluctuations that can be troublesome in visual science experiments. A number of ways to avoid this problem are discussed. 相似文献

Two experiments were designed to demonstrate the existence of a self-fulfilling prophecy mediated by nonverbal behavior in an interracial interaction. The results of Experiment 1, which employed naive, white job interviewers and trained white and black job applicants, demonstrated that black applicants received (a) less immediacy, (b) higher rates of speech errors, and (c) shorter amounts of interview time. Experiment 2 employed naive, white applicants and trained white interviewers. In this experiment subject-applicants received behaviors that approximated those given either the black or white applicants in Experiment 1. The main results indicated that subjects treated like the blacks of Experiment 1 were judged to perform less adequately and to be more nervous in the interview situation than subjects treated like the whites. The former subjects also reciprocated with less proximate positions and rated the interviewers as being less adequate and friendly. The implications of these findings for black unemployment were discussed. 相似文献

This paper discusses the general problem of measuring the association between an independent nominal-scaled variableX and a dependent variableY whose scale of measurement may be interval, ordinal or nominal. The theoretical foundations of a wide range of asymmetric association measures are discussed. Some new measures are also suggested. Fifteen of these association measures, some previously suggested, some new, are singled out for a computer-assisted numerical study in which we compute the value actually taken by each measure under a wide variety of conditions. This comparative study provides important insights into the behavior of the measures. 相似文献

Videotapes were made of actors playing the role of engaged couples in an ostensible interview with a research psychologist. Couples either gazed at each other or did not gaze, used each other's name five times or not at all, and touched each other or did not touch. The videotaped interviews were shown to groups of introductory psychology students for ratings on ten polar adjective scales. Gaze proved to be the most important variable, with gazing couples rated significantly more positively than non-gazing couples on all dimensions. Touching couples were rated more favorably than non-touching couples and name using couples received less favorable ratings than non-name using couples. Results of the study were related to equilibrium theory and discussed within the framework of other research relating nonverbal variables to interpersonal attraction. 相似文献

The accuracy and computational speed of three algorithms (spectral analysis, period analysis, and period amplitude analysis) for the extraction of spectral estimates from time-series data are empirically evaluated in the context of a neuropsychological experiment that requires estimates of power in the standard electroencephalographic frequency bands. 相似文献

The effect of a counselor working directly with college teachers on a specific student learning problem—oral nonparticipation in discussion classes—was explored. Seven college history instructors viewed with a counselor videotaped excerpts of their own classroom discussion sessions. During playback sessions the counselor modeled and verbally and nonverbally reinforced certain instructor behaviors seen on video. Four instructors viewed tapes individually (IT) with the counselor; three instructors viewed tapes in a group (GT) with the counselor. Results: (1) Instructors reported video-playback counseling was very helpful in changing their behavior in the classroom; (2) Instructors became more aware of how verbal and nonverbal cues influence student behaviors; (3) Small group playbacks seemed as effective as individual playback procedure. 相似文献

Group psychotherapy theory and technique are presented with the goals of helping group practitioners working with difficult clients: 1) develop a treatment plan; 2) create a therapeutic alliance; 3) foster a responsive group climate; and 4) utilize the therapist's countertransferential reactions in dealing with therapeutic conflict. Historical modifications of the analyst's role in the development of group psychotherapy are noted. Emphasis is give to the recognition of therapist-client identifications in order to separate feelings induced in the therapist from countertransferential reactions, to enable the practitioner to respond appropriately to the affective and inspirational substratum of therapeutic groups. 相似文献

English-language reports on the relationship between extraversion and performance in extra-sensory perception tasks are reviewed. Data reported show that significant confirmations of a positive relationship occur at over six times the chance error rate whilst only one significant reversal of the effect is to be found. It is suggested that this consistency in the experimental reports reflects a real positive relationship between the two variables. Possible mechanisms underlyinf the effect are discussed and suggestions for studying them are made with an emphasis on improvement of methodology. 相似文献

The purpose of the present study was to undertake a six-month follow-up of the communication and problem-solving skill level of those premarital couples trained in the Ridley, Avery, Harrell, Leslie, and Dent (in press) study. Fifty-nine percent of the original sample (14 experimental couples and 18 control couples) were given a behavioral assessment of communication and problem-solving ability six months after training. Results indicated that the experimental group, relative to the control group, had significantly higher pretest to follow-up scores on communication skills and the problem-solving steps. Discussions centered on the implications of skill maintenance over time and possible directions of future research. 相似文献

A simulated group training model serves as the modality which best captures a balance of didactic and experiential elements, en vivo supervision and consultation, working with the trainees' most difficult clients in a therapeutic group. Limitations of this approach can be most appropriately addressed by personal psychotherapy outside of the training program. 相似文献
