A synthesis of cultural materialism and behavior analysis might increase the scientific and technological value of both fields. Conceptual and substantive relations between the two fields show important similarities, particularly with regard to the causal role of the environment in behavioral and cultural evolution. Key concepts in Marvin Harris's cultural materialist theories are outlined. A distinction is made between contingencies at the behavioral level of analysis (contingencies of reinforcement) and contingencies at the cultural level of analysis (metacontingencies). Relations between the two kinds of contingencies are explored in cultural practices from paleolithic to industrial sociocultural systems. A synthesis of these two fields may offer the opportunity to resolve serious problems currently facing modern cultures.  相似文献

A recent clinical study of outpatient psychotherapy groups in a community mental health center explored the linkage between group leadership variables, group climate, and outcome. The study involved nine outpatient therapy groups, over 50 group clients, and several group therapists. A repeated measures design involving assessment of clients' outcome and level of functioning, group leadership style, and group climate was used to assess changes over a 6-month period. The findings suggest: 1) a reduction in symptoms and improved functioning for clients; 2) a similarity of perceptions by members and leaders of perceived leadership behaviors and group climate; 3) the presence of direct and indirect influences of group climate and leadership behavior on clients' outcome; and 4) a linkage between leadership behavior and group climate with the theoretical orientation of the group. The findings of the research are discussed in relation to the understanding of specific effects in group psychotherapy and the implications for construction of group psychotherapy theory.The authors would like to thank Robert Dies, Ph.D., for his helpful suggestions in the early phase of this study; Roy MacKenzie, M.D., for permission to use the Group Climate Questionnaire; Diane DePalma, Ph.D., for permission to use the Global Leadership Behavior Index; Chris Boltwood, B.A., for her untiring efforts in administering the instruments and coding and entering the data; and most importantly, the psychotherapy group members and the group therapists for their cooperation in this endeavor—without their help, this clinical study would not have been possible.A version of this paper was presented at the Annual Meeting of the American Group Psychotherapy Association, 1987, New Orleans, Louisiana. Lenore Phipps, R.N., M.S., C.S., was formerly Director, Group Psychotherapy Program at Park Ridge Mental Health Center, Rochester, now in private practice at Guild Medical Center, Norwood, MA 02062.  相似文献

Legal and nonlegal factors influencing the civil commitment recommendations of psychologists and psychiatrists separately and as a whole were investigated using an experimental design. One hundred and seventy-six psychologists and psychiatrists made recommendations for or against commitment for a series of clinical vignettes wherein the five facets of commitment criterion, legal committability, clinical treatability, alternative resources and presence of psychosis were systematically varied. Results revealed that all facets contributed independently and in combination to the commitment decisions of participants as a whole. It was concluded that mental health professionals may utilize a variety of types of information, beyond the relevant legal criteria, in making actual decisions to initiate civil commitments.  相似文献

A computer-controlled system that detects spontaneous activity (locomotion and rearing) and diurnal activity rhythms in small animals is described. Automatic recording of subtotals during test periods provides data about habituation (nonassociative learning). The system is relatively inexpensive to construct. Fabricated from highly reliable circuit components, it provides replicable measures that enable comparisons between different experimental treatments to be made using parametric statistics.  相似文献

A technical issue in auditory spatial attention research is how best to provide low-cost, accurate control of the frequency, duration, and location of acoustic signals. Three solutions to the problem are compared: use of the internal oscillator of the Apple lIe, use of a Mountain A/D+D/A card, and use of an external oscillator chip. The unique advantages and drawbacks of each system are discussed. All share some common problems of external speaker interface, timing control, and interface with the software. Hardware and software solutions implemented on the Apple-Psych system are discussed, along with data that demonstrate the precision control achieved with the system.  相似文献

Difficulties with the Microsoft BASIC function for generating random numbers (RND) are cited and new problems reported. Fixes are suggested that allow use of some of the speed of the original function and that produce greatly improved pseudorandom numbers. A published generator is combined with the RND function as a compromise solution.  相似文献

Members of the Society for Computers in Psychology responded to a survey concerning their programming practices and language use. The results reveal current hardware and software use; relationships among computer science training, task, and language choice and usage; and areas in which attention to some structured programming principles might improve the code that psychologists write.  相似文献

In contrast to theoretical discussions about potential professional liability of clinical ethicists, this report gives the results of empirical data gathered in a national survey of clinical medical ethicists. The report assesses the types of activities of clinical ethicists, the extent and types of their professional liability coverage, and the influence that concerns about legal liability has on how they function as clinical ethicists. In addition demographic data on age, sex, educational background, etc. are reported. The results show that while nearly one third (28.9%) of the ethicists regularly make recommendations about patient care, only 10.8% of them regularly make entries in the medical record; only approximately half (53.0%) of them are covered by professional liability (malpractice) insurance; and the vast majority (84.3%) of them say that concerns about legal liability do not influence the way they function as clinical ethicists.  相似文献

This paper evaluates intervention programs in schools using the theoretical framework of the critical sociology of education, and most specifically, the extent to which schools are autonomous from the larger society. Three different types of intervention programs are reviewed: drug abuse prevention, sex education, and programs to change gender stereotypes, all of which were found to have limited effectiveness. Schools appear unable to change behaviors which are prevalent in a culture because they themselves are strongly influenced by that culture, and because adolescents are influenced by forces outside school. To be effective, such interventions would seem to require governmental agencies, community groups, and the media to work with the schools in order to influence the culture and thus produce behavioral changes in individuals.  相似文献
