Since the 1970s, investigative profilers at the FBI's Behavioral Science Unit (now part of the National Center for the Analysis of Violent Crime) have been assisting local, state, and federal agencies in narrowing investigations by providing criminal personality profiles. An attempt is now being made to describe this criminal-profile-generating process. A series of five overlapping stages lead to the sixth stage, or the goal of apprehension of the offender: (1) profiling inputs, (2) decision-process models, (3) crime assessment, (4) the criminal profile, (5) investigation, and (6) apprehension. Two key feedback filters in the process are: (a) achieving congruence with the evidence, with decision models, and with investigation recommendations, and (b) the addition of new evidence. 相似文献

Early and late in 18 2-day solo-led psychodynamic groups for mental health professionals, 185 participants rated their own behavior and each other's on composite measures of Acceptance versus Rejection of Self (ARS) and of Others (ARO). Only on ARO were leaders consistently rated more favorably than members. Considered by group units, members' mean ratings of peers made modest but significant early-to-late advances on both measures. About two-thirds of all intergroup differences in members' net shifts were separately predictable from ratings of leaders by self and also by pooled group members each time. Groups' ARO shifts were best predicted by members' ratings of leaders toward Warm versus Cold. Leader self-ratings toward Accepts others versus Rejects others best predicted groups' ARS shifts. Featuring interpersonal behavior's two principal dimensions and bridging the common split between studies of group outcome versus group processes, these findings generally support Roger's (1959) theory of personality change. 相似文献

Homosexuals, bisexuals, and heterosexuals were compared on self-reported love preferences and ideals. In general, the three groups tended to agree on ideal characteristics of love objects, love relationships, and love related beliefs. Nevertheless, the groups differed significantly on preferences and beliefs related to love-object sex, residential proximity, ethnic background, physical intimacy, freedom from feelings of jealousy, sexual fidelity, emotional intimacy, and the importance of religious or legal acknowledgment.An early version of this paper was presented at the Annual Meeting of the National Council on Family Relations, in San Francisco, October 1984, Journal Series No. 2973 of the Hawaii Institute of Tropical Agriculture and Human Resources. 相似文献

This article describes some essential computer skills needed by psychology students seeking careers in business. It is suggested that students become familiar with computer software packages in the following areas: statistical analyses, wordprocessing, spreadsheets, data base managers, and graphics. Discussion is provided.Paper presented at the 57th Annual Convention of the Midwestern Psychological Association, Chicago, Illinois, May 1–3, 1985. 相似文献

This paper describes a simple infrared photocell circuit that is inexpensive and easy to construct. The light source and detector are housed inexpensively and are focused so the light and detector may be separated over significant distances. The circuit may be used in a variety of conditions, including total darkness and bright fluorescent lighting, without having to readjust or recalibrate the circuitry. Output from the circuit may be used to drive other transistors or electromechanical relays. With minimal additional circuitry and hardware the signal may be interfaced with an Apple computer. 相似文献

Many behavioral scientists are aware of the advantages of a systematic approach to research and the development of software used in research. However, coordinated and systematic efforts to develop instructional materials in the behavioral sciences are relatively rare. This paper and the symposium of which it is a part describe a systematic effort funded by FIPSE to assess the needs for microcomputer tools and courseware in the undergraduate curriculum in psychology and to stimulate the development of high-quality materials. The conceptual bases for development of materials are vertical and horizontal integration-the development of courseware that spans the curriculum from introductory to advanced, specialized, courses, and the systematic use of materials within a course and across courses and subject areas. The activities of the project, as well as implications for other computer-based development projects, are discussed. 相似文献
