The Good Behavior Game (GBG) is an effective intervention package for decreasing disruptive behavior in various populations and environments. There is, however, limited research evaluating the GBG with preschoolers. Furthermore, few studies have evaluated the effects of components of the GBG, and of those that have, most have done so only after exposure to the GBG package. We evaluated the effects (a) of the GBG on disruptive behavior of preschoolers during group instruction and (b) the major components of the GBG before and after implementation of the GBG package (c) at both the group and individual level. Results suggest that the GBG package was necessary for decreasing disruptive behavior. However, after exposure to the GBG, a response‐independent contingency was effective for maintaining low levels of disruptive behavior at both the group and individual level. 相似文献

In this contribution, the authors defi ne and discuss the educational boundary in analytic training, which they believe is an often neglected and useful concept in psychoanalytic education. The framework on which their discussion rests includes the recent attention of psychoanalysts to issues of boundaries and ethics. Their understanding of how clinical work affects the mind of the analyst educator, as well as the ways the personalities of various analysts affect their dealings with faculty peers and students, are the other cornerstones of their discussion. The authors contend that many of the institutional problems encountered in the training of analysts can be better understood when viewed through the prism of the educational boundary. They present examples which illustrate several of the ways psychoanalytic educators complicate the training experience of candidates, offer specifi c explanations as to why analysts struggle as they try to manage their educational interventions, and indicate in a discussion of potential remedies that those behaviors might be avoided if the educational boundary is in focus. They also provide an example of how the educational boundary can be more effectively managed. 相似文献

Countertransference is a central topic in analytic work and in the literature. The concept of countertransference includes a basic question which has been understood in different ways. The author attempts to differentiate between the psychoanalyst's transference and his countertransference in the analytic process. It is hard to draw a line between them; analysts are always on the edge. The analyst's transference will be explored and described using three approaches: narcissism, regression profile and the analyst's phase of life. Regression profile is a new concept developed by the author, which may help us to understand the core of the analyst's transference in the analytic situation. She illustrates the topic by clinical vignettes. 相似文献

It was investigated whether commonly used factor score estimates lead to the same reproduced covariance matrix of observed variables. This was achieved by means of Schönemann and Steiger’s (1976) regression component analysis, since it is possible to compute the reproduced covariance matrices of the regression components corresponding to different factor score estimates. It was shown that Thurstone’s, Ledermann’s, Bartlett’s, Anderson-Rubin’s, McDonald’s, Krijnen, Wansbeek, and Ten Berge’s, as well as Takeuchi, Yanai, and Mukherjee’s score estimates reproduce the same covariance matrix. In contrast, Harman’s ideal variables score estimates lead to a different reproduced covariance matrix. 相似文献

The regression trunk approach (RTA) is an integration of regression trees and multiple linear regression analysis. In this
paper RTA is used to discover treatment covariate interactions, in the regression of one continuous variable on a treatment
variable withmultiple covariates. The performance of RTA is compared to the classical method of forward stepwise regression. The results of two
simulation studies, in which the true interactions are modeled as threshold interactions, show that RTA detects the interactions
in a higher number of cases (82.3% in the first simulation study, and 52.3% in the second) than stepwise regression (56.5%
and 20.5%). In a real data example the final RTA model has a higher cross-validated variance-accounted-for (29.8%) than the
stepwise regression model (12.5%). All of these results indicate that RTA is a promising alternative method for demonstrating
differential effectiveness of treatments.

The purpose of this research work was to develop a methodology to model arm movement in normal subjects and neurologically impaired individuals through the application of a statistical modelling method. Thirteen subjects with Parkinson's disease and 29 normal controls were recruited to participate in an arm motor task. An infrared optoelectronic kinematic movement analysis system was employed to record arm movement at 50 times per second. This study identified the modified extended Freundlich model as one that could be used to describe this task. Results showed that this model fit the data well and that it has a good correspondence between the observed and the predicted data. However, verification of the model showed that the residuals contained a sizeable autocorrelation factor. The Cochrane and Orcutt method was applied to remove this factor, which improved the fit of the model. Results showed that Parkinson's disease subjects had a higher autocorrelation coefficient than the normal subjects for this task. A positive correlation (r(s) = 0.72, p < 0.001) was found between the Langton-Hewer stage and the autocorrelation coefficient of PD subjects. This finding suggests that if autocorrelation is positively correlated with disease progression, clinicians in their clinical practice might use the autocorrelation value as a useful indicator to quantify the progression of a subjects' disease. Significant differences in model parameters were seen between normal and Parkinson's disease subjects. The use of such a model to represent and quantify movement patterns provides an important base for future study. 相似文献

Van Breukelen offers a promising method for modeling both response speed and response accuracy. However, the underlying conception of both dependent measures is somewhat flawed, leading the author to conclude that the approach possesses limitations that, under revised assumptions, may not hold. The central misconception, and a set of related misconceptions, is addressed, and it is suggested that this approach holds a good deal of promise for application in the perceptual and cognitive sciences. 相似文献

On a test of dimensionality in redundancy analysis 总被引:1,自引:0,他引:1
Lazraq and Cléroux (Psychometrika, 2002, 411–419) proposed a test for identifying the number of significant components in redundancy analysis. This test, however, is ill-conceived. A major problem is that it regards each redundancy component as if it were a single observed predictor variable, which cannot be justified except for the rare situations in which there is only one predictor variable. Consequently, the proposed test leads to drastically biased results, particularly when the number of predictor variables is large, and it cannot be recommended for use. This is shown both theoretically and by Monte Carlo studies.The work reported in this paper was supported by Grant A6394 to the first author from the Natural Sciences and Engineering Research Council of Canada. 相似文献
