Differences in school behavior and achievement between students from intact, reconstituted, and single-parent families were analyzed. Students from intact two-parent families had fewer absences and tardies, higher grade point averages, and fewer negative and more positive teacher behavioral ratings than did those from reconstituted and single-parent families. 相似文献

Two studies examined the effects of a reductive treatment versus instruction-based treatments on the generalized reduction of problem behaviors. Each study involved a detailed analysis of multiple problem behaviors performed by school-aged youth with severe intellectual disabilities. The analysis examined the contrasting effects of one of two different positive intervention procedures (teaching a positive alternative behavior or providing additional teacher assistance during instruction) versus blocking and/or verbally reprimanding a problem behavior. The focus of each analysis was on the covariation of multiple problem behaviors within functional response classes. Results of the investigation indicated that when only one member of the response class was blocked, a collateral increase was observed in one or more different problem behaviors from the same response class. Alternatively, when 1 participant was taught a functionally equivalent mand response, all problem behaviors in the response class were reduced. Problem behaviors also were reduced for the remaining participant by presenting antecedent teacher assistance. Implications of the research extend to analysis of covariation within response classes and to procedures that result in generalized reduction of problem behaviors within a response class. 相似文献

Three experiments are reported that represent a reexamination of the missing-number method (Buschke, 1963b) of estimating short-term memory span. The missing-number task involved presenting a random sequence of all but one of the numbers of a known reference set and asking subjects to identify the missing number. Experiment 1 introduced a modified missing-number task that included two missing items and two choices made by the subject. With a large decline in performance for the second choice relative to the first, it is possible that only the second choice was subject to output or retrieval interference. An alternative explanation is that subjects output the number with the weakest memory representation as their first response. By postcuing subjects to report their two choices in a forward or backward sequence, Experiment 2 provided evidence against the importance of output interference and support either for the importance of retrieval interference or for the "weakest-first" hypothesis. However, with a paradigm that replaced only correctly identified missing numbers, a prediction that subjects would select the number with the weakest memory representation as their first response was not confirmed in Experiment 3. Instead, retrieval interference was implicated to explain the first-choice superiority found in Experiments 1 and 3. The results were interpreted in terms of the TODAM model of Murdock (1982, 1987, in press). 相似文献

Given that the mind is the brain, as materialists insist, those who would understand the mind must understand the brain. Assuming that arrays of neural firing frequencies are highly salient aspects of brain information processing (the vector functional account), four hurdles to an understanding of the brain are identified and inspected: indeterminacy, micro-specificity, chaos, and openness.My thanks to the editor of this issue and an unnamed referee for many pointed comments and helpful suggestions. 相似文献

This article describes a FORTRAN 77 subroutine which manipulates the audio hardware facilities on the Amiga microcomputer.
The subroutine may be instructed to produce either tones or musical notes on any combination of four independent channels.
Frequency, volume, and type of waveform are passed to the subroutine as parameters. Some limitations in relation to sound
production on the Amiga are discussed. 相似文献

In an attempt to extend Bandura's theory of self-efficacy, we investigated the hypothesis that increases in self-efficacy, based on mastery experiences, would lead to improvements in mood and problem solving among dysphoric subjects.College students (N=79), classified as dysphoric or nondysphoric by the Beck Depression Inventory, were randomly assigned to anagram training groups that received bogus bar graphs suggesting either task ease or difficulty. Before and after training, subjects rated themselves on depressive affect (DACL) and self-efficacy. A difficult anagram task and a final DACL rating completed the procedure.Anagram training conditions did not lead to differential self-efficacy. However, multiple regression analyses showed that self-efficacy was related to depressive symptoms. Greater DACL decreases after training were seen in dysphoric subjects who reported higher posttraining self-efficacy. This improved mood is consistent with Bandura's theory. An unexpected finding among dysphoric subjects was that the higher their self-efficacy was, the lower was their final anagram performance. It appears that dysphoric/high self-efficacy subjects may have become more demoralized than dysphoric/low self-efficacy subjects when they encountered a need for much greater effort expenditure on the difficult anagram task.The findings suggest that skills training interventions which raise self-efficacy may be most effective in reducing depressive symptoms. The relevance of effort expenditure to the development of competine in depressed undiriduals appears to merit further investigation.where he served previously as Director of Clinical Psychology and as Chairperson of the Department of Psychology.Jeffrey Schwartz, Ph.D., a clinical psychologist, has been a staff member at the Cliffwood Mental Health Center in Englewood, New Jersey for the past five years.

Using bar code technology to automate data collection provides a rapid and reliable alternative to paper-and-pencil tracking or keyboard entry into pocket or laptop computer. An array of bar code symbols is printed on a data menu, with a unique symbol corresponding to each possible observation. Bar code symbols are scanned using hand-held readers, which record the event, log the observation time, and store data for transfer to a personal computer. Advantages of the bar code monitoring system include: (1) ease of use by staff with minimal technical training, (2) reduced data entry errors and increased entry speed, (3) reliable portable operation, and (4) low-cost hardware. While the bar code system described here is used for behavioral monitoring in a residential treatment setting for the developmentally disabled, with minimal modification this system can be adapted for use in a wide variety of research and clinical applications. 相似文献
