本研究以188名1318岁青少年为研究对象,采用脑电波超慢涨落分析技术(简称ET),对其12导联脑电波(EEG)进行了记录和分析,并对其表象能力进行了考察。重点探讨了表象能力的发展与脑α波特点之间的关系。结果表明:(1)13~18岁青少年随年龄增长,对表象任务正确反应需要的时间逐渐下降,其反应时变化的转折时期为16岁;(2)男女生之间差异不显著;(3)在句图匹配和心理旋转作业中好组10Hzα波的比率均高于差组,其它频率差异不显著,说明表象能力好组与占主频的α波相联系。 相似文献

Four experiments were conducted to examine variables associated with response practice as an instructional technique for individuals with intellectual disabilities. In Experiment 1, the effect of the cover component in the "cover write" method was evaluated, as were the comparative effects of written versus oral practice of spelling words by rehabilitation clients. The results showed that the cover procedure generally did not enhance performance over and above that produced by practice alone, and written practice generally was not superior to oral practice. Experiment 2 demonstrated that less response practice (i.e., five times) was as effective as more practice (i.e., 10 and 15 times) for teaching spelling to adolescents with developmental disabilities. Experiments 3 and 4 also showed that even less response practice (i.e., one time) was as effective as more practice (five times), and irrelevant practice following errors was as effective as relevant practice for teaching spelling and sight vocabulary to adolescents with behavior disorders and developmental disabilities, respectively. The findings suggest that a parsimonious procedure of limited response practice and positive reinforcement may be effective for the tasks and populations studied. 相似文献

The purpose of this study was to assess the impact of parental divorce on young adult development. One hundred twenty-five participants provided demographic information and completed the PAFS-Q (college version) and the conflict subscale of the Family Environment Scale. Results indicate that parental divorce and family conflict significantly affect developmental task attainment. The interactions between sex and age and family structure (i.e., single-parent or stepfamily) were also significant predictors of post-divorce task attainment. Implications of these results for therapists as well as recommendations for future research are provided.This is a revised version of a paper presented at the annual conference of the American Psychological Association, Los Angles, California, August 1994. 相似文献

Previous research has demonstrated that destructive behavior may be reduced through noncontingent presentation of attention when attention is identified as the stimulus responsible for behavioral maintenance. Because it may not always be possible to deliver attention in all situations, we examined the extent to which alternative stimuli that have been identified through a choice assessment would substitute for attention (the functional analysis—based reinforcer) in a noncontingent reinforcement procedure. Prior to treatment, functional analyses demonstrated that the destructive behavior of 2 clients with mental retardation was maintained by adult attention. Next, a stimulus choice assessment identified highly preferred tangible items for the 2 clients. Finally, we compared the effectiveness of two noncontingent reinforcement procedures: continuous noncontingent access to attention and continuous noncontingent access to the tangible item identified in the choice assessment. For both clients, these noncontingent reinforcement procedures reduced destructive behavior. The results are discussed in terms of the clinical implications for the treatment of destructive behavior using functional and alternative stimuli. 相似文献

We identified 3 clients whose destructive behavior was sensitive to negative reinforcement (break from tasks) and positive reinforcement (access to tangible items, attention, or both). In an instructional context, we then evaluated the effects of reinforcing compliance with one, two, or all of these consequences (a break, tangible items, attention) when destructive behavior produced a break and when it did not (escape extinction). For 2 clients, destructive behavior decreased and compliance increased when compliance produced access to tangible items, even though destructive behavior resulted in a break. For 1 client, extinction was necessary to reduce destructive behavior and to increase compliance. Subsequently, when the schedule of reinforcement for compliance was faded for all clients, destructive behavior was lower and fading proceeded more rapidly when compliance produced multiple functional reinforcers (i.e., a break plus tangible items or attention) and destructive behavior was on extinction. The results are discussed in terms of the effects of relative reinforcement value and extinction on concurrent operants. 相似文献

Establishing operations can alter problem behaviors by changing the momentary value of reinforcers associated with those problem behaviors. If establishing operations (EOs) precede the presentation of discriminative stimuli (SDs) for problem behaviors, it may be possible to introduce neutralizing routines that both reduce the value of reinforcers associated with problem behaviors and decrease the occurrence of problem behaviors. The present study examined this logic with 3 adolescents with severe intellectual disabilities. Initial functional analyses indicated that problem behaviors were motivated by either escape or tangible items. Functional assessment interviews identified possible establishing operations that were associated with the occurrence of problem behavior and indicated that these establishing operations occurred over 1 hr before presentation of the SD for problem behaviors. We used an alternating treatments design to examine problem behaviors during instruction under four conditions: EO + SD, SD only, EO only, and neither SD nor EO. For all 3 participants, problem behaviors occurred almost exclusively during the EO + SD condition. A further analysis compared the EO + SD condition when neutralizing routines were embedded between the EO and the SD. Results from an ABAB reversal design supported the effectiveness of neutralizing routines to reduce these problem behaviors. Applied and theoretical implications are discussed. 相似文献

This investigation used functional analyses to identify the social variables that maintained the inappropriate social-communicative behaviors of 2 adolescent students with mental retardation. Analyses were performed in the students' classrooms with the assistance of peers and teachers. The results of these assessments were used to identify appropriate, functionally equivalent behaviors that the students were taught to self-monitor. Findings showed substantial decreases in inappropriate social responding and increases in the use of appropriate social skills. 相似文献

This study examined the relations among developmental test scores, infants' demographic characteristics, and cry features. Cry features were strongly related to developmental test scores at all ages, suggesting that use of the infants' cry characteristics can help to identify those infants at greatest risk for later developmental problems. 相似文献

Although recent federal legislation has led to a proliferation of supported employment programs throughout the country, little information is available that documents the success of these programs. In the present study, we examined the effect of different consumer characteristics and alternative supported employment service delivery models on key employment outcomes including hourly wage, hours worked per week, increase in earnings after supported employment participation, and level of integration on the job. The employment outcomes of a sample of 1,550 individuals receiving supported employment services through 96 local programs in eight states were analyzed to determine the effects of the key independent variables of primary disability and type of employment model. Results indicate that all groups of individuals, regardless of their primary disability, benefited significantly from supported employment participation. Further, data indicate that the individual placement model generated employment outcomes superior to those resulting from group employment options, particularly work crews. Implications of the results for future program development activities are discussed. 相似文献
