Smoking, body weight, and their effects on smoking behavior: a comprehensive review of the literature 总被引:19,自引:0,他引:19
This article provides a comprehensive review of the research on smoking and body weight. The relationships between smoking and body weight are evaluated in 70 cross-sectional and longitudinal investigations. The mechanisms responsible for differences in body weight are discussed, the weight-related issues that promote smoking behavior are reviewed, methods for reducing postcessation weight gain are summarized, and future research directions are proposed. A proposed working research model for studying the relationship between smoking, energy balance, and weight gain is offered. It is concluded that smoking and body weight relationships are closely related and pose significant challenges for smoking researchers. 相似文献

Lakatos (1993) reported interesting data that indeed support “the hypothesis that the extent of spatial separation between successive sound events directly affects the perception of time intervals between these events” (p. 139). The present comment is an attempt to show that, as far as the horizontal plane is concerned, Lakatos’s hypothesis was already answered qualitatively by Axelrod and coworkers (Axelrod & Guzy, 1968; Axelrod, Guzy, & Diamond, 1968) in their studies of attention shifting, and by ten Hoopen and coworkers, who quantified the amount of “interaural time dilation” (Akerboom, ten Hoopen, Olierook, & van der Schaaf, 1983; ten Hoopen, 1982; ten Hoopen, Vos, & Dispa, 1982). Nonetheless, Lakatos’s study is very worthwhile. It originated from the realm of “apparent motion paradigms,” but I will argue that the study rather used an “auditory streaming paradigm,” and that the data is a welcome contribution to elucidate how the perceptual processes of auditory stream formation and interaural time dilation interact. 相似文献

To increase the effectiveness of parent education interventions, family therapists can address those factors that shape the way in which parents interact with their children. This article presents ecological theory as a framework that can help clinicians expand the range of their parent training efforts. In order to assess the utility of ecological theory for clinical practice, the present study empirically explored the ways in which selected characteristics of parents, children, and the family context related to mothers' parenting behavior. Specific recommendations for family therapists who employ parent training techniques are offered. 相似文献

Examination of boundary regulation can provide family therapists with a framework to describe both the functioning of family systems and personal systems (i.e., the intrapsychic functioning of individual family members). In the present study, late adolescents' perceptions of boundary regulation within their family systems (i.e., ratings of family health, communication, leadership, expressiveness, cohesion, and family conflict) were related to regulation of their personal boundaries (i.e., self-reported personal competence, distress, and patterns of defense mechanism use). In addition, personal system variables reliably discriminated between adolescents who described their families as psychologically healthy versus psychologically unhealthy. 相似文献

The Diana (Diana v. State Board of Education, Note 1) and the Larry P. (Larry P. v. Riles, Note 2) litigations led to decertification of thousands of California EMR students and their return to the regular program. Allegations, including those of biased testing, went largely uncontested in order that change in special education could result from court mandate, but the allegations left the psychologists in a libeled state. A study of cumulative records and psychologists files in 12 representative districts permitted a comparison of the EMR placement of those later decertified (D) with matched nondecertified (EMR). Other than a small mean difference in IQ at placement, nothing was found to support various allegations. Records showed no systematic differences betweeen D and EMR groups in pre-EMR reasons for referral nor in teacher marks, discnfirming beliefs in referral of higher functioning students for deportment rather than for academic failure. Districts permitted a mean of at least two years in regular placement before assessment, attesting to class failure rather than IQ as the initial and necessary basis for EMR identification (no D-EMR difference in this either). The data permit a conclusion that the work of the school psychologists in the EMR placement was professionally competent, given the guidelines in effect at the time. 相似文献

This research examined the effects of a self-instruction intervention on the relationship between cognitive level and conceptual tempo. Preoperational and concrete operational children received the Matching Familiar Figures Test prior to and after serving in either a no training control group, a content only control group, or a self-instruction group. Children in the content only control group received the same set of self-guiding strategy statements as those in the self-instruction group but without overt rehearsal of the statements. Cognitive level and conceptual tempo were strongly related; preoperational children tended to be classified as impulsive, concrete operational chidlren, as reflective. Although cognitive level predicted overall performance, with concrete operational children being more successful and more reflective than preoperational children, the influence of training was similar for both groups. On posttest, children in the self-instruction groups made more correct responses and were more reflective than children in the other two training groups. 相似文献
