B. F. Skinner's Science and Human Behavior (1953) became the main source of my understanding of behavior during my first semester as a college professor in 1955 at Kansas University. It has continued to exert a major influence throughout my career as the basis for a completely deterministic science of behavior, as a handbook to be consulted as a first step in dealing with any issue in behavior analysis, and as a tutorial in behavioral interpretive analysis--in the use of a small number of behavioral concepts and principles to understand behavior of all degrees of complexity. I describe four general interpretive orientations or maxims that are of broad significance for behavior analysis, and also two underappreciated major theoretical contributions. 相似文献

Psychopathy appears to be comprised of two broad dimensions: impulsivity/antisocial behavior and interpersonal detachment/callousness. This study examined the extent to which variance in these 2 psychopathy trait dimensions was associated with common or unique genetic, shared, and nonshared environmental factors in two independent samples of reared together 16–18-year-old male twins. One sample included 142 monozygotic (MZ) and 70 dizygotic (DZ) pairs; the other sample included 128 MZ and 58 DZ pairs. Boys completed the Minnesota Temperament Inventory (MTI), a 19-item measure that contains separate subscales: Antisocial and Detachment. Variance in the Antisocial and Detachment scales was associated with additive genetic factors and neither scale was associated with shared environmental factors. As expected, the bivariate biometric analysis suggested genetic influence on the covariance of the scales. The results are consistent with theoretical models of psychopathy that posit some independence in the etiology of the two major trait dimensions of psychopathy. 相似文献

Behavioral geneticists sometimes use metaphorsto describe the role of genes in humanbehavior. In this paper, five sample texts areanalyzed: a popular book, a textbook, ascientific review article, and two originalscientific articles representing differentapproaches in behavioral genetics. Metaphorsare found in all the different kinds of sampletexts, not only in the popular book and thetextbook. This suggests that metaphors are usednot only for rhetorical or pedagogical purposesbut play a more fundamental role in scientificunderstanding. In the sample texts, themetaphors tend to be antideterministic, i.e.,they do not imply genetic determinism butstress the interaction of multiple genes andmultiple environmental factors. No conclusioncan be drawn, however, as to whetherantideterminism is representative ofpresent-day behavioral geneticists in general.Certain historically important metaphors thatmay imply genetic determinism are qualified,avoided, or explicitly rejected. There aretensions between some of the metaphors, makingthem difficult to combine. All the metaphorsthat are used appear empirically apt, howeversometimes only with certain qualifications. 相似文献

The authors investigate two competing hypotheses about how chronic vividness of imagery interacts with the vividness and salience of information in decision making. Results from four studies, covering a variety of decision domains, indicate that chronic imagery vividness rarely amplifies the effects of vivid and salient information. Imagery vividness may, in fact, attenuate the effects of vivid and salient information. This is because, relative to nonvivid imagers, vivid imagers rely less on information that appears obvious and rely more on information that seems less obvious. This tendency is so robust that vividness of imagery may amplify the effects of vivid information only when this information is the only information available in the decision field. The findings seem to reflect vivid imagers' tendency to totally immerse themselves in a decision problem and scrutinize the available information creatively. 相似文献

Object relations family therapy (ORFT) is a psychoanalytically based approach for the treatment of couples and families which stresses the importance of past relationships. The therapist assumes a parentlike role and provides a holding environment in which clients can explore unconscious motivations. This paper will discuss the applicability of this method to genetic counseling. The case of a couple seen for recurrent trisomies will be presented and used as an example to discuss how ORFT might serve as a framework in a genetic counseling session. 相似文献

Genetic counseling and the many roles a genetic counselor must assume to provide quality genetic health care are becoming increasingly complex, especially when the genetic condition is rare, and DNA testing is costly and not yet routinely used. A case study of a couple with a family history of retinoblastoma and their pursuit of DNA testing for prenatal diagnosis is presented. The case study illustrates the instrumental role of the genetic counselor in advocating for clients for genetic services such as DNA testing and in educating insurance companies in the nature and importance of such services to achieve improved client health care outcomes. 相似文献

Open-ended, qualitative interviews with women to whom amniocentesis was offered were analyzed to understand how women made sense of these tests. We found that women, whether tested or not, negotiated with biomedical information. They transformed it through identifiable processes, then wove it with their own instincts and beliefs and with their personal experiences, thereby creating embodied knowledge on which their decisions were based. Women who were and were not tested may have differed from each other when categorized on the basis of a final, binary choice, but they were more alike than unalike in reaching this point. The apparent importance of embodied knowledge suggests the critical role of the listening activities of the genetic counselor and of awareness of the validity and importance of women's complementary ways of knowing and doing in understanding the uses and meanings of prenatal genetic testing. 相似文献

The advent of cloning animals has created a maelstrom of social concern about the ethical issues associated with the possibility of cloning humans. When the ethical concerns are clearly examined, however, many of them turn out to be less matters of rational ethics than knee-jerk emotion, religious bias, or fear of that which is not understood. Three categories of real and spurious ethical concerns are presented and discussed: 1) that cloning is intrinsically wrong, 2) that cloning must lead to bad consequences, and 3) that cloning harms the organism generated. The need for a rational ethical framework for discussing biotechnological advances is presented and defended. 相似文献
