Three sources of potential error in reaction time measurement may occur when raster scan CRT displays are used to present stimuli: phosphor persistence, sweep delay, or transmission delay. For most applications, only the third source of error is likely to be significant.  相似文献

The effectiveness of a package treatment for reducing nailbiting was studied. The package was composed of both positive procedures aimed at teaching adaptive behavior to substitute for nailbiting and negative procedures aimed at advancing skills for suppressing nailbiting. The design of the study permitted an analysis of the contributions of both positive and negative components of the package. Subjects assigned to combined, positive, negative and placebo groups received four weekly treatment sessions, and changes in their nailbiting behavior were compared with untreated controls. As in previous studies, nonspecific factors such as demand and attention to ones nails were found to be important determinants of outcome. In addition, positive procedures were found to be substantially more important than negative procedures in the maintenance of reductions in nailbiting over a 4-month follow-up period.  相似文献

Four domains of research in adolescent suicide are reviewed: (1) the role of psychopathology, (2) family history of psychopathology, (3) mental health treatments, and (4) firearms in the home. Based on the extant literature, recommendations are made for changes in training, service delivery, and public policy. Among the recommendations for training professionals are: an emphasis on diagnostic proficiency, skill and attentiveness in the assessment of the entire family unit, and assessment of the availability of firearms in the home. With respect to changes in service delivery, we recommend treatment of the entire family system, and treatment of psychiatric and substance abuse problems in the same setting, and we show the need for a continuum of intensity of care from inpatient to outpatient. With respect to policy changes, we recommended parity of mental and physical health insurance coverage, screening for psychiatrically at-risk youngsters in schools and physicians' offices, providing funding to support a continuum of care between inpatient and outpatient, and gun control laws to restrict access to handguns. We believe that these changes can result in a substantial reduction in the adolescent suicide rate.  相似文献

In the August 1993 issue ofJournal of Applied Psychology, Deniz Ones, Vish Viswesvaran, and Frank Schmidt published a monograph on the validity of integrity tests as revealed by meta-analysis. They concluded that integrity tests have substantial and generalizable predictive validity for criteria of both overall job performance and counterproductive behaviors on the job (e.g., disciplinary problems, absenteeism, rule breaking, violence on the job, theft, etc.). During the Fall of 1992, the authors sent a preprint of this study to David Lykken of the University of Minnesota, stimulating the exchange of letters that is reproduced here. The doubts, concerns, and feelings about integrity tests expressed by Professor Lykken are likely to be shared by others. The responses by Professors Schmidt, Ones, and Viswesvaran attempt to show that these worries are unfounded.  相似文献

Personality and Coping: Three Generations of Research   总被引:1,自引:0,他引:1  
ABSTRACT This article introduces the Journal of Personality 's special issue on coping and personality. It first presents a historical overview of the psychological study of how people cope with stress and identifies three generations of theory and research: (a) the psychoanalysts and the ego development school, which tended to equate personality and coping strategies; (b) the transactional approach, which appeared in the 1960s and emphasized situational and cognitive influences on coping while downplaying the role of individual differences; and (c) the most recent, "third generation," whose work is represented in this special issue and focuses on the role of personality in coping while maintaining strong operational distinctions among coping, personality, appraisal, and adaptational outcomes. This introduction concludes with a discussion of unresolved conceptual and methodological issues and a brief orientation to the third-generation articles that follow in this special issue.  相似文献
