In the present work the effect of two task variables on transfer were studied: shape of the track-circular or triangular; and target speed-constant or variable. One or both of these variables was changed on transfer. Experimental conditions were (a) 10 preshift and 10 post-shift trials, and (b) 20 single-trial alternations of two tasks. 22 groups of 12 Ss each were tested. Condition (a) showed positive transfer with single variable change and zero or negative transfer with simultaneous change in two variables, and condition (b) annulled all transfer effects. Results are discussed in terms of commonality between tasks and receptor and perceptual anticipation. 相似文献

Methodological and empirical issues in research on action information feedback (AIF) are discussed, with particular reference to the procedures and results of Annett (1970). Positioning responses practiced under conditions of AIF training are learned, though generally less well than under terminal IF conditions. Effects obtained as a result of AIF training may be subject to variations in movement extent required, gain and other transformations, frequency, temporal locus, and mode of augmentation, many aspects of which remain to be systematically studied. 相似文献

Subjects made a speeded stylus movement along a track to a stop and simultaneously performed a simple reaction-time task designed to assess the processing demands of the movement task. Movement task variables were: (a) number of alternative ending positions — either one or two — with the choice executed during movement, and (b) presentation time for the endpoint signals in the two-choice conditions, either prior to movement initiation (immediate) or during movement execution (delay). Processing demands were higher during all movement conditions than in a control condition that did not require movement. Processing demands during execution of the one-and two-choice movement with immediate signals did not differ. However, processing demands during the two-choice movements with delayed signals were higher than demands during the two-choice movement with immediate signals. 相似文献

We attempted to identify the personal characteristics that influence confidence in an investment decision in an experiment administered to 1,359 subjects nationwide. Multiple regression was used to control statistically for variation among subjects and to develop a model of investment decision confidence. The most striking finding was that women had significantly lower confidence in an investment task than men, after controlling for all other relevant variables and characteristics including the amount of the investment decision itself. Familiarity with and present attitude about investing in the stock market, college credit hours in accounting and finance, experience in evaluating common stocks, the current level of the stock market, and the investment decision itself (the amount to be invested) were also found to be significant. Age, value of personal portfolio, years of college, and years of business experience were not significant characteristics. 相似文献

Abstract The researchers conducted a needs assessment survey of practicing school-based occupational therapists to determine the incidence of grief within existing caseloads, current awareness of the issue, related concerns, and willingness or resistance to address grief in the intervention environment. The survey was administered to a representative sample of 150 school-based therapists throughout the state of Ohio. Fifty-six therapists responded with usable data. The results suggest that the students who are currently on occupational therapy (OT) caseloads face a large number of grief issues. Although a majority of therapists reported addressing grief issues, only a small percentage typically do so for a variety of reasons. The school therapists offered a number of explanations for the limited follow-through on this issue. These findings support the profession's recent efforts to further establish occupational therapy as a well-recognized and respected provider of interventions to address the mental health and psychosocial needs of children in school settings. 相似文献

AbstractDuring the last years, different types of violence have severely damaged Mexico. In this paper we examine the consequences that violence could have in children, one of the most vulnerable segments of society. In short, we predict that exposure to any type of violence will lead to higher depression and that this could be explained through the effects of violence on childhood well-being. Our hypothesis was supported in two studies, showing that exposure to street violence (Study 1, N = 607) and exposure to collective violence (Study 2, N = 172) can increase childhood depression. Moreover, in both studies, this effect was explained by the decrease of childhood well-being caused by violence exposure. The implications of these results are discussed. 相似文献

The effectiveness of a parenting program was examined with an Australian sample regarding improved parent knowledge, parental sense of competence, and child behavior. One hundred and sixteen parents and their children were randomly assigned to three conditions: a two-session group based intervention, a two-session self-administered individual intervention, or to a waitlist control group. Across both treatment modalities results reveal a significant increase in parental satisfaction, efficacy, and a reduction in child problem behavior. Improvements were maintained at 3-months follow-up. Results indicate the individual self-administered format enhanced treatment gains relative to the group format. 相似文献

Fifty-nine college students used a modified version of the Treatment Evaluation Inventory-Short Form to evaluate the acceptability of four versions of a sexual abuse prevention program for 10-year-old children. The four versions include an information-based training approach or a behavioral skills training (BST) approach with a focus on strangers or known individuals as perpetrators of sexual abuse. A significant effect was found for both training method and type of perpetrator, with information-based approaches involving strangers as perpetrators rated the most acceptable. These results suggest that college students were most comfortable with sexual abuse prevention training programs for 10-year-olds when the programs did not involve an active rehearsal component and when the program focused on abuse perpetrated by a stranger rather than a known individual. 相似文献

This study evaluated the effectiveness of a group mentoring program that included components of empirically supported mentoring and cognitive behavioral techniques for children served at a community mental health center. Eighty-six 8- to 12-year-old children were randomly assigned to either group mentoring or a wait-list control group. Group mentoring significantly increased children's reported social problem-solving skills and decreased parent-reported child externalizing and internalizing behavior problems after controlling for other concurrent mental health services. Attrition from the group mentoring program was notably low (7%) for children. The integration of a cognitive behavioral group mentoring program into children's existing community mental health services may result in additional reductions in externalizing and internalizing behavior problems. 相似文献

ABSTRACT This article addresses the lack of communication between child behavior analysis (CBA) and what has been referred to as “mainstream clinical child psychology” (MCCP). It is suggested that the emotionality of the aversive-nonaversive debate is attributable in part to a lack of information exchange among these two sub-specialties. Distinct contributions of CBA and MCCP are examined in each of the following four areas: population, assessment, research, and treatment. Recommendations are made for enhancing child clinical psychology by (a) promoting constructive communication, and (b) integrating components of the two approaches. 相似文献
