The need for efficient and practical assessment techniques of the multidimensional nature of chronic pain remains paramount in clinical settings. Visual analogue scales (VASs) and simple behavioral observation methods have been proposed as efficient, reliable, and valid measures of the subjective (sensory and affective) and overt behavioral aspects of the pain experience. The relationships among VASs and the UAB Pain Behavior Scale were examined among 48 chronic pain patients. Ratings of overt behavior were significantly related to both the VAS sensory and VAS affective ratings. Regression analysis indicated that the VAS scores accounted for significant amount of the variance (27.7%) in UAB scores. Moreover, the affective dimension of self-reported pain tended to be more strongly related to the visible manifestations of pain than were ratings of pain intensity.  相似文献

The debt of neuropsychology to the epilepsies.   总被引:3,自引:0,他引:3  
Both neuropsychology and psychology in general have been enhanced markedly by brain-behavior models derived from the study of the epilepsies. A significant body of neuropsychological concepts originated or were confirmed through epilepsy-based treatment and research. These concepts include the peri-Rolandic homunculus, the role of the hippocampal-temporal lobe complex in cognitive memory, hemisphere plasticity for speech in childhood, the intracarotid amytal procedure for determining hemisphere memory patency, and hemisphere-based models of cognition confirmed through human commissurotomy. Personality and social-emotional research in epilepsy are additional areas in which new conceptual models grounded in psychological science can both repay our debt to the epilepsies and provide much needed psychological research and treatment.  相似文献

Traits that are influenced by a configuration--rather than by a simple sum--of polymorphic genes may not be seen to be genetic unless one studies monozygotic twins (who share all their genes and thus all gene configurations) because such "emergenic" traits will tend not to run in families. Personal idiosyncrasies that have been found to be surprisingly concordant among MZ twins separated in infancy and reared apart may be emergenic traits. More speculatively, important human traits like leadership, genius in its many manifestations, being an effective therapist or parent, as well as certain psychopathological syndromes may also be emergenic. These ideas reemphasize the importance of the role played in human affairs by genetic variation.  相似文献

The primary responsibility of the American Psychological Association's (APA) Committee on Standards in Research (CSR) is to advise the APA on issues and standards related to the protection of human participants in psychological research. A related goal is to enhance the use of good ethical practices by APA members. The purpose of this article is to foster the view of research ethics not as an affront to the integrity of sound research, but as opportunities for scientific rewards, including increased understanding of the meaning of data, enhanced recruitment, and the inclusion of more representative samples. Three ethical practices are discussed as examples of this general premise: respect for confidentiality, use of debriefing, and assurance that participants are noncoerced volunteers. The Committee's intent is to promote consideration of these issues, not to promulgate specific guidelines or procedures.  相似文献

Injury is the fourth leading cause of death for all Americans and the most frequent cause of death for those from age 1 to 45. Moreover, injury is associated with higher treatment costs and with greater lost life-years than the other three leading causes of death. Traffic accidents are the leading cause of severe brain injury, including most paraplegic and quadriplegic cases. Because injury control is essentially psychological, there are many opportunities for psychologists to contribute, both to scientific research on the causes of injury and to clinical interventions for injury control.  相似文献

Redefining the science-practice relationship and professional training.   总被引:3,自引:0,他引:3  
A revised conception of the relationship between psychological science and professional practice is proposed in the light of postmodern changes in perspectives on knowledge. Positivistic science, which has dominated the traditional interpretation of scientist-practitioner training, is considered from a constructivist point of view to be only one possible foundation of psychological knowledge. It is argued that the knowledge base of the profession should be derived with diverse methods and from multiple sources, including the knowledge of practice. The mutuality of science and practice is emphasized. An evolving framework for understanding the epistemology of practice, based on cognitive psychology, is presented. Emphasis on broadened choices of research methods, the development of reflective skills, and better linkage between teaching in the domains of research and practice are urged. Suggestions for research related to scientific training and the knowledge processes of practice are offered.  相似文献

This study examined a system for fading teacher prompts to children who served as peers in peer-initiation interventions for young children with disabilities. A teacher taught peers to direct social initiations to children with disabilities, provided verbal prompts for those initiations, and introduced a system that provided peers with visual feedback about the social interactions of the children with disabilities. She then systematically withdrew the verbal prompts to peers, and subsequently faded the visual feedback system. Peer initiations increased when the intervention began and resulted in increases in social interaction for the children with disabilities. As the teacher systematically faded the prompts and visual feedback to the peers, social interaction continued at the levels found during intervention and was maintained during a short maintenance period.  相似文献
