THE EFFECTIVENESS OF REINFORCEMENT,RESPONSE COST,AND MIXED PROGRAMS ON CLASSROOM BEHAVIORS1

Six elementary school children served as subjects in an experiment comparing the relative effectiveness of (1) token reinforcement, in which children received tokens for attending and for correct arithmetic performance; (2) response cost, in which children received “free” tokens at the start of a period but lost them for inattention and for arithmetic performance below a specified level; and (3) a combination of both token reinforcement and response cost. During training, the six subjects received all three procedures in counterbalanced sequence. The effects of the three procedures were assessed by a within-subject comparison divided into three phases: (i) baseline, (ii) training, (iii) withdrawal of tokens. Introduction of the three token procedures markedly increased the two dependent measures. However, there were no differences across the procedures in the amount of change produced in either attending behavior or arithmetic performance. During baseline, the subjects averaged 29% attending behavior and 6.4 correct problems. These levels increased to 85% for attending behavior and 11.4 correct problems for arithmetic performance during training. Removal of all token procedures significantly decreased attending behavior (to an average of 65%), but produced a nonsignificant reduction in arithmetic performance (to an average of 7.6 correct problems). There was evidence that this lack of differential effects of the three token procedures was not due to an inability to discriminate among them. Furthermore, the subjects were evenly divided in their preference for the three procedures.     

Effects of two teacher-presentation rates on off-task behavior, answering correctly, and participation

Off-task behavior, correct answering, and participation during beginning reading instruction were recorded for two low-achieving first-grade children during two different rates of teacher presentation. A slow-rate presentation (A) was compared with a fast-rate presentation (B) in an ABABAB design. In slow-rate presentation, there was a delay between the children's response and introduction of the next task. In fast-rate presentation, there was no delay. A new teacher taught during the final AB phases, which allowed for a brief replication. Both teachers were reminded on a fixed-interval 90-sec schedule throughout all phases of the experiment to praise the subjects, thus preventing a confounding of social praise and rate of teacher presentation. Fast-rate presentation was accompanied by a lower per cent occurrence of off-task behavior for both Subjects 1 and 2. For Subject 1, correct answering and participation were more frequent during all three fast-rate phases. For Subject 2, correct answering and participation were more frequent during the fast-rate phases after the first reversal.     

中小学师生的校园暴力内隐观研究

本研究用自编问卷对2386名中小学生和504名中小学教师进行了调查,结果表明,中小学师生普遍认可比较严重的身体攻击和性骚扰为校园暴力,不太认可言语攻击为校园暴力。学生的内隐观存在性别、城乡和年级差异,教师的内隐观基本不受性别、城乡、年级和学历影响。教师比学生更认可身体攻击为校园暴力,而学生比教师更认可言语攻击、财产破坏和一般性的体罚为校园暴力。     

中学生偶像崇拜与学业自我概念、学业成绩的关系研究

研究主要采用问卷法 ,选取北京市某普通中学 42 8名初一至高三的学生进行研究 ,结果表明 :(1 )有偶像的中学生人数显著高于无偶像的人数 ,“歌星影星”与“著名人士”是其崇拜的主流。 (2 )学业自我概念及其各维度在有无偶像之间不存在显著差异。 (3)主要偶像类型对学业自我概念具有显著主效应。 (4 )有无偶像和主要偶像类型对学业成绩均没有显著主效应。

本研究以难易程度不同的两个打洞操作作业 ,对弱智儿童和正常儿童的感知 动作技能进行了多种参数的测查。结果发现 :两类儿童在理解操作要点、操作速度、操作动作协调性以及操作正确性等各个方面都有明显的差异。同时通过比较 ,对弱智儿童感知 动作技能的特点 ,从外部肢体动作方式和内部智力动作方式两方面进行了详细的分析 ,并在此基础上对弱智儿童的感知 动作技能的教育与训练提出了建议 ,这对弱智学校改革教学、提高教学质量具有重要意义。     

《中学生心理健康诊断测验》结构的探索及修改

在浙江省8个城市的6所高中和6所初中,采取分层整群抽样方法选取初一到高三600名学生,用修改后的《心理健康诊断测验》(MHT)进行了测查,着重检验该测验的结构。结果发现,因素分析所获取的因素与原测验相一致,但对原测验的项目进行了一些删减。因素分析和相关分析结果以及内部一致性系数显示,修改后的问卷具有较高的信度,其效度也符合心理测量的要求。

小学儿童谦虚行为的发展研究

谦虚行为是一种中国特有的亲社会行为,在有关儿童道德判断的跨文化研究领域具有比较特殊的意义.本研究通过实验室实验对311名7、9、11岁小学儿童的谦虚行为进行了有益的探索.结果发现,儿童的谦虚行为不仅与年龄因素有关,而且还会受到社会情境因素的影响.     

Developmental Delays at Arrival,Early Intervention Enrollment,and Adopted Chinese Girls’ Academic Performance and Internalizing Problems in Adolescence

The author investigated the extent of developmental delays in girls adopted from China, their subsequent early intervention (EI) enrollment, and how the delays and EI were related to their academic performance and internalizing problems in adolescence. The sample included 180 adolescent girls (M = 13.4 years, SD = 2.0 years) who were adopted at 3–23.5 months (M = 11.5 months, SD = 3.7 months). Data on the adopted Chinese girls’ delays at arrival and EI enrollment in physical therapy (PT) and speech–language therapy (SLT) were collected from the adoptive mothers at the Baseline; data on the adopted Chinese girls’ present academic performance and internalizing problems were collected from the adoptive mothers and adopted girls at Wave 4 six years later. Data analyses revealed that 55% of the adoptees had moderate-to-severe delays when first arrived at the adoptive homes. Motor delays significantly increased the odds for PT (odds ratio [OR] = 3.98, 95% CI [2.18, 7.82], p <.001) and SLT (OR = 2.36, 95% CI [1.50–3.72, p <.001). Social-cognitive delays also significantly increased the odds for PT (OR = 1.90, 95% CI [1.36, 2.63], p <.001) and SLT (OR = 1.63, 95% CI [1.22, 2.17], p <.001). Motor delays were negatively associated with academic performance but positively associated with internalizing problems. General linear modeling showed that the adoptees who had developmental delays at arrival and subsequently enrolled in EI scored significantly lower on academic performance than their peers who had delays but did not enroll in EI, as well their peers who had no delays and did not enroll in EI. Implications of these findings are discussed.
