The Role of Rehearsal in Joint Control

Behavior analysts have offered accounts of the behavior involved in matching to sample and delayed matching to sample. But until recently have not offered a behavioral analysis of generalized matching-to-sample. The concept of joint control, however, seems especially suited to such an analysis The present study used a joint-control procedure to train five adult women to acquire a generalized sequencing behavior using an unfamiliar language. After joint-control training the participants were able to produce untrained picture sequences, and blocking the mediating response during the sequencing task resulted in a reduction in the number of accurate sequences. These results clearly support response mediation as a precurrent to various kinds of complex human behavior.     

Echoic and Self-Echoic Responses in Children

Eleven typically developing children were assessed on the accuracy of prompted self-echoic responses following a 5-s delay from their initial echoic response, replicating procedures in Esch, Esch, McCart, and Petursdottir (2010) that compared discrepancies between echoic and self-echoic scores of autistic and typically developing children following a 2-s delay. We compared the two studies in terms of age, level tested, and echoic/self-echoic discrepancy scores. Age and test level differences were found to be statistically significant. Results are discussed in terms of discrepant self-echoic performance and self-echoic rehearsal as it relates to participant age, test level, motivating variables, and the development of complex behavior.     

A Parametric Analysis of Rehearsal Opportunities on Procedural Integrity

Behavioral skills training (BST) involves instruction, modeling, rehearsal, and feedback. Despite its empirical support, the literature provides little to no guidance regarding the best way to implement rehearsal to ensure accurate implementation of behavioral procedures. Thus, the purpose of this study was to conduct a parametric analysis of rehearsal opportunities within a BST package. We evaluated the effects of 1, 3, and 10 rehearsals with feedback on correct implementation of functional analysis (FA). Regardless of the number of rehearsals, 18 undergraduate participants effectively learned to implement FA conditions. The most efficient training involved the use of single rehearsals with feedback until meeting mastery criterion. Participants maintained integrity during a follow-up session and rated the use of rehearsal as highly acceptable.     

道德行为选择中的“道德想象力”——读杜威《人性与行为》

杜威反对道德行为选择中脱离经验的教条化与僵化做法，提出了“道德想象力”概念。“道德想象力”是使不在场成为在场、从“能是”感知“所是”的能力。道德行为选择过程离不开想象、慎思、抉择等道德想象力的发挥，其要旨是理解当下行动的意义并努力增加当下行动的意义，使道德行为成为充满活力与创造性的艺术。     

词汇记忆策略与词汇成绩的关系——对西南交通大学新生词汇记忆的调查

以文秋芳的学习策略理论为基础,运用词汇测试卷和词汇学习情况问卷对西南交通大学大一新生的词汇水平和词汇记忆策略的使用进行调查,结果表明：（1）大学新生支持“背单词”,而不太赞同“自然习得单词”的观点;（2）词汇分数高、低两组学生在单词记忆策略使用方面无明显差并,但高分组学生整体策略的使用明显多于低分组;（3）大一新生在记忆词汇时运用多种记忆策略,其中使用频率较高的是重复策略和管理策略,使用频率较低的是活用、上下文和单词表策略;（4）大一学生的词汇成绩和策略使用具有显著相关性。其中．管理策略与学生词汇成绩显著相关,并有预测力。
