The present study examines the reliability and construct validity of the Dutch version of the Psychopathy Check List: Youth Version (PCL:YV) in a sample of male adolescents admitted to a secure juvenile justice treatment institution (N = 98). Hare's four-factor model is used to examine reliability and validity of the separate dimensions of psychopathy. Interrater reliabilities are good to excellent for the PCL:YV total score and most factor scores, except for the affective factor. Several suggestions are offered for optimizing reliability of this factor. Finally, meaningful associations between PCL:YV scores and scores on the Minnesota Multiphasic Personality Inventory-Adolescent and the Interpersonal Checklist-Revised support the construct validity of the PCL:YV total score as well as the four factors in the Dutch context. 相似文献

In this study the effectiveness of differential reinforcement of other behavior (DRO) with tokens was assessed in the treatment of various topographies of disruptive behavior in the classroom with five children who were multiply handicapped. Prior to implementation of the treatment, reinforcer assessment was conducted to identify items to be used as back-up reinforcers. Data were analyzed using time-series analysis. Results show that DRO tokens were highly effective in decreasing disruptive behavior of all participants. ©1997 by John Wiley & Sons, Ltd. 相似文献

It would be possible to be affirmed that the most of the educational goals that modernity assumes, they settled down from
the Renaissance. The postmodern age, in its critic to the modern period, demands the recovery of some losses. At the time
of fast changes as it happens in the Renaissance, the Humanism originates a fruitful debate. According to the authors protagonists,
the controversy became a dialogue plenty of common questions to which we find in the contemporary discussion. The reflection
on the thought of one of the most representative and well-known authors, Comenio, it serves to think on the encounter of traditions
in Philosophy of Education. He is a thinker who supplies the basis for his educational practice on a Philosophy of education
and projects a reform to confront some problems that in the essential are repeated today.

Research with adults has shown that the distortion of visual word features, and in particular of the multiletter features within words, hampers word recognition. In this study, "CaSe MiXiNg" was employed to examine the effect of disrupting visual word features on the acquisition of orthographic knowledge in children. During the training, 18 beginning and 27 advanced readers (in Grades 2, 4, and 5) repeatedly read a set of pseudowords in either lowercase or mixed case. During this training, case mixing appeared to impair reading speed in both reader groups. At posttest, 1 day after the training, case format was either the same as or different from that during the training. Lowercase pseudowords were recognized faster after a lowercase training than after a mixed-case training. In a second study, case was found not to affect the rapid naming of single letters. The combined results suggest that case mixing disrupted the multiletter features in pseudowords and that the disruption of these features can affect the acquisition of orthographic knowledge. 相似文献

First-letter naming was used to investigate the role of phonology in printed word perception in children with and without dyslexia. In 2 experiments, all children showed faster first-letter-naming times in a congruent condition than in an incongruent condition, which suggests that phonology is a fundamental constraint in the printed word perception of readers of all levels and all skills. An explanation in terms of a recurrent network put forward by G. C. Van Orden and S. D. Goldinger (1996) is discussed to account for the apparent paradox in the reading behavior of readers with dyslexia, that is, that in first-letter naming, dyslexic readers appear to show phonological congruity effects, whereas in pseudoword reading, their phonological knowledge appears to be deficient or absent. 相似文献
