The mapping of the human genome has reawakened interest in the topic of race and genetics, especially the use of genetic technology to examine racial differences in complex outcomes such as health and intelligence. Advances in genomic research challenge psychology to address the myriad conceptual, methodological, and analytical issues associated with research on genetics and race. In addition, the field needs to understand the numerous social, ethical, legal, clinical, and policy implications of research in this arena. Addressing these issues should not only benefit psychology but could also serve to guide such thought in other fields, including molecular biology. The purpose of this special issue is to begin a discussion of this issue of race and genetics within the field of psychology. Several scholars who work in the fields of genetics, race, or related areas were invited to write (or had previously submitted) articles sharing their perspectives.

Controversies are rampant in contemporary psychology concerning the appropriate method for observing consciousness and the role inner experience should play in psychological theorizing. These conflicting orientations reflect, in part, methodological differences between natural science and human science interpretations of psychology. Humanistic psychology and philosophical phenomenology both employ a human science approach to psychology that seeks to explain behavior in terms of a person's subjective existence. Maslow's and Heidegger's formulations are both fulfillment theories in that they specify moral values that suggest how life ought to be lived. Natural science methodology rejects the possibility that moral imperatives can be validated, whereas human science methodology allows phenomenological convictions to justify recommendations about a fulfilled life and a good society. The social role of psychology is analyzed within the framework of phenomenological convictions and scientific truth. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Presents a comment on "Psychological treatments" (see record 2004-21168-001) by D. H. Barlow. Barlow proposed that we distinguish between the terms "treatment" and "psychotherapy." The author believes that not only is the distinction unnecessary, but that its implications could have negative consequences for the field of clinical psychology. It is the proposed distinguishing feature that treatments are "specifically tailored to the pathological process that is causing the impairment and distress" that is most problematic. Clinical psychology does not need a distinction that further exacerbates the split between researchers and practitioners. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Presents the official listing of accredited internship and postdoctoral residency programs. It reflects all committee decisions through July 17, 2005. The Committee on Accreditation has accredited the doctoral internship and postdoctoral residency training programs in psychology offered by the agencies in this article. The original date of accreditation, listed for each program, is the day on which the program's accredited status became effective. Also listed for each program is the date of the next regularly scheduled site visit. Program review is governed by the "Guidelines and Principles for Accreditation of Programs in Professional Psychology" (G&P). (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Review of book The Robot's Rebellion: Finding Meaning in the Age of Darwin by Keith E. Stanovich (see record 2004-95228-000). In his interesting scholarly book, The Robot's Rebellion, Stanovich leads us on a journey to find meaning in a world populated by mortal biological vehicles, the robots, put on earth to replicate their masters' selfish genes. If the genes do a satisfactory job programming the robots, then the genes replicate in perpetuity and are, therefore, immortal. Stanovich's basic assumptions are: a) vehicles are designed to replicate genes; b) at least in human animals, the brain houses two minds; c) the first mind, System 1 or The Autonomous Set of Systems, evolved much earlier in evolutionary history than did the second mind, System 2 or the Analytic System; d) System 1 is associative, parallel, fast to respond, and designed to automatically serve its genetic master; e) System 2 is rule-based, serial, slow to respond, not aware of System 1 functioning but sometimes privy to System 1 output, controls executive functioning, and is capable of self-evaluation and leading the rebellion against its genetic master; and, f) memes, culturally generated ideas passed on by nongenetic means, can sometimes be as effective as System 1 at squashing the rebellion. These assumptions are derived from work in cognitive science and evolutionary biology, and provide a solid foundation for the book. Both the metaphor and the basic assumptions are embedded in detailed and informative reviews of decision theory, evolutionary psychology, memetic theory, rational philosophy, and utility theory. The interweaving of metaphor and review provides a framework that allows Stanovich to make inferences to help the general reader understand "the implications of modern science" (p. xi). He also develops criteria to evaluate memes that are needed in his quest to find meaning in human existence. In combination with the basic assumptions, these criteria are used to create an ethical ideology that will be embraced by some readers.

With the increased popularity of qualitative research, researchers in counseling psychology are expanding their methodologies to include mixed methods designs. These designs involve the collection, analysis, and integration of quantitative and qualitative data in a single or multiphase study. This article presents an overview of mixed methods research designs. It defines mixed methods research, discusses its origins and philosophical basis, advances steps and procedures used in these designs, and identifies 6 different types of designs. Important design features are illustrated using studies published in the counseling literature. Finally, the article ends with recommendations for designing, implementing, and reporting mixed methods studies in the literature and for discussing their viability and continued usefulness in the field of counseling psychology.
