THE DEVELOPMENT AND FUNCTIONAL CONTROL OF READING-COMPREHENSION BEHAVIOR1

Reading comprehension, indicated by motor behavior and multiple-choice picture selection called for in written instructions, was taught to an autistic child using verbal prompts, modelling, and physical guidance. The child was rewarded for correct behaviors to training items; nonrewarded probes were used to assess generalization. Probable maintaining events were assessed through their sequential removal in a reversal design. Results showed: (a) following acquisition, performance was maintained at a near-100% level when candy, praise, attention, and training were removed, (b) absence of other persons was correlated with a marked decrease in performance, whereas their presence was associated with performance at near 100%, and (c) performance generalized to probes and across experimenters. Rewards, which may have been reinforcing during acquisition, did not appear necessary to maintain later performance. Instead, presence of others (a setting event) was demonstrated to have control over maintained performance.     

Generation Identity and the Reminiscence Bump: Memory for Public and Private Events

Participants ranging in age from 30 to 70 years free-recalled when they had learned public and private items of news. When responses were plotted in terms of age of participant at time of encoding, it was found that peak recall for public items of news was in the period when participants were aged 10 to 19 years whereas peak recall of private items of news occurred in the period when participants were aged 20 to 29 years. A second study confirmed this pattern of an early reminiscence bump for public news. It is proposed that these two components of the reminiscence bump reflect, respectively, a period of formation of generation identity in the second decade of life and a period of formation of intimate relationships in the third decade.     

EFFECTS OF SETTING EVENTS ON THE PROBLEM BEHAVIOR OF STUDENTS WITH SEVERE DISABILITIES

Two studies analyzed the effects of preceding setting events on the problem behavior of students with severe disabilities. Using ABAB withdrawal designs, the occurrence versus nonoccurrence of preceding setting events was analyzed in relation to the frequency of problem behavior. Data were collected throughout a student's school day, with interventions focusing upon the elimination of setting events that occurred before school. The results indicate that (a) the occurrence of preceding setting events was related to higher frequencies of problem behavior and (b) interventions designed to eliminate preceding setting events were consistently associated with low frequencies of problem behavior.     

A matter of habit? Stressful life events and cognitive flexibility in 15-month-olds

Exposure to chronic stress is associated with habitual learning in adults. We studied the origins of this association by examining the link between stressful life events and infant cognitive flexibility. The final sample consisted of N = 72 fifteen-month-old infants and their mothers. Mothers completed a survey on pre- and postnatal negative life events. To assess chronic stress physiologically, infant and maternal hair cortisol concentrations were determined for cortisol accumulation during the past 3 months. Each infant participated in two cognitive tasks in the laboratory. An instrumental learning task tested infants’ ability to disengage from a habituated action when this action became ineffective (Seehagen et al., 2015). An age-adequate version of the A-not-B task tested infants’ ability to find a toy at location B after repeatedly finding it at location A. Correlations between cortisol concentrations and postnatal negative life events (number, perceived impact) did not yield significance. Infant and maternal hair cortisol concentrations were not correlated. Infants’ ability to shift to a new action in either task, controlled for acute stress, correlated neither with pre- and postnatal negative life events nor with cortisol concentrations. Taken together, these results indicate that the potential link between long-term stress exposure and cognitive flexibility might not be present in samples with low levels of psychosocial stress.     

心理弹性、负性生活事件和抑郁症状的关系：钢化效应和敏化效应

该研究追踪调查汶川地震后1573名青少年,考查心理弹性、生活事件和抑郁症状的关系,以探讨幸存者的心理修复过程。结果表明:（1）心理弹性既能直接预测抑郁症状,也能通过抑郁症状间接影响生活事件;（2）生活事件既能直接预测心理弹性,也能通过抑郁症状间接预测心理弹性;（3）抑郁症状既能直接影响心理弹性,也能通过生活事件间接影响心理弹性。结论：灾后不同特征的青少年心理修复过程不同,存在"钢化效应"和"敏化效应"。     

压力性生活事件对工读生毒品使用影响：有中介的调节效应

考察家庭功能对压力性生活事件与工读生毒品使用之间关系的调节效应以及领悟社会支持对此调节效应是否具有中介效应。采用压力性生活事件量表、家庭功能评定问卷、领悟社会支持问卷、毒品使用问卷对514名工读生进行研究。结果表明：（1）家庭功能对压力性生活事件与工读生毒品使用之间关系具有调节效应;（2）这种调节效应以领悟社会支持为中介变量。压力性生活事件对工读生毒品使用的影响是有中介的调节效应。     

领悟社会支持、应对效能和压力性生活事件对青少年学业成就的影响机制

为揭示领悟社会支持与青少年学业成就的关系,以及应对效能的中介效应和压力性生活事件的调节效应,采用领悟社会支持问卷、应对效能问卷、压力性生活事件量表和学业成就问卷对1687名青少年进行研究。结果显示：（1）领悟社会支持能够促进青少年的学业成就;（2）应对效能对领悟社会支持与学业成就的关系具有中介效应;（3）压力性生活事件能够调节应对效能的中介作用。因此,领悟社会支持对学业成就的影响是有调节的中介效应。     

Major world events and discrimination

It is known that a major world event caused by one group can influence perceptions of other social groups. The impact of the events of September 11, 2001 on religious and ethnic discrimination in the UK was assessed. Of seven ethnic groups, Pakistanis and Bangladeshis, who were primarily Muslim, reported the greatest increase between pre- and postevent discrimination. So, the attacks on the USA by al-Qaeda, a radical Islamic organization, activated discrimination against people of Islamic faith in the UK. These results highlight links between world events and intergroup relations, and may serve to remind norm violators that the harm they do to people of other groups can impact people of groups perceived to share their values, even in geographically distant places.     

大学生领悟社会支持的影响因素研究

该研究以371名大学生为被试,考察了个体的幸福感、控制感和压力对领悟社会支持的影响。结构方程模型分析的结果显示：个体属性和情境因素都直接或间接影响着大学生对社会支持的理解和评价;个体属性的影响相对比较重要;在情境因素中,累积压力比当前压力的影响更为重要。本研究结果表明,领悟社会支持是在个人属性的作用下,个体在不断应对日常生活压力的过程中形成和发展的。
