Foreign Language Training Transfer: Individual and Contextual Predictors of Skill Maintenance and Generalization

Foreign language proficiency is a critical skill in which many U.S. military personnel receive extensive training. However, very little research has examined the factors associated with the successful transfer of this training. This study therefore investigates the impact of individual and contextual variables on two different types of foreign language skill transfer measures in a military context. Archival data were analyzed from 133 U.S. Army Special Forces (Green Berets) teams, including 919 Soldiers who had completed job-required foreign language training. Results indicate that initial skill acquisition had a positive impact on both the maintenance and generalization of language skills. The posttraining time interval between training and transfer measurement was negatively associated with skill maintenance, suggesting significant skill decay over time. The team context also accounted for significant variability in skill transfer, and the team mean skill level moderated the relationship between individual initial skill and subsequent generalization to job performance.     

An evaluation of multiple‐schedule variations to reduce high‐rate requests in the picture exchange communication system

Using procedures similar to those of Tiger, Hanley, and Heal (2006), we compared two multiple‐schedule variations (S+/S– and S+ only) to treat high‐rate requests for edible items in the Picture Exchange Communication System (PECS). Two individuals with autism participated, after they showed persistent requests for edible items after PECS training. Stimulus control was achieved only with the multiple schedule that involved presentation of a discriminative stimulus during reinforcement components and its removal during extinction components (S+ only). Discriminated requests were maintained for the 1 participant who experienced schedule thinning.     

VALIDATION OF SOCIAL SKILLS OF ADOLESCENT MALES IN AN INTERVIEW CONVERSATION WITH A PREVIOUSLY UNKNOWN ADULT

Seventy convicted young male offenders were videotaped during a 5-min standardized interview with a previously unknown adult. In order to determine the social validity of the behavioral components of social interaction for this population, measures of 13 behaviors were obtained from the tapes. These measures were then correlated with ratings of friendliness, social anxiety, social skills performance, and employability made by four independent adult judges from the same tapes. It was found that measures of eye contact and verbal initiations were correlated significantly with all four criterion rating scales. The frequencies of smiling and speech dysfluencies were both significantly correlated with ratings of friendliness and employability. The amount spoken was found to be a significant predictor of social skills performance whereas the frequency of head movements influenced judgments of social anxiety. The latency of response was negatively correlated with social skills and employability ratings and the frequency of question-asking and interruptions correlated significantly with friendliness, social skills, and employability ratings. Finally, the levels of gestures, gross body movements, and attention feedback responses were not found to influence judgments on any of the criterion scales. The implications of the study for selection of targets for social skills training for adolescent male offenders are discussed.     

工作记忆刷新及其训练效应——经颅直流电刺激的作用

工作记忆刷新是执行功能的重要成分之一。以往研究结合n-back任务和经颅直流电刺激（transcranial direct current stimulation ,tDCS）技术探究刷新能力,发现tDCS技术能够一定程度上增强刷新训练效果并引起大脑神经元相关活动的变化,其增强效果能够维持一定的时间,且能够迁移到其他认知任务之中。但tDCS的干预效果在各项研究中存在一定的差异性。其作用效果会受到训练任务与训练方式、电流强度、电极布局和训练时间间隔等因素的影响。未来研究可以探索tDCS结合刷新训练的最佳刺激参数,以获得最优化的干预效果。     

Examination of the effects of traditional and modern martial arts training on aggressiveness

This study addresses two issues associated with the relationship between martial arts training and aggressiveness. The first is a replication of two recent findings, that for students trained traditionally, length of training varies inversely with aggressiveness, whereas for students trained in a “modern” style, length of training and aggressiveness are related directly. Second, we examine two competing explanations for the findings above. One is the training hypothesis, which holds that elements present in traditional approaches to martial arts but absent in modern approaches act to reduce aggression levels of students. These may include meditation, philosophy, emphasis on the kata (the forms of combat), etc. The alternate hypothesis, selection, holds instead that these findings are artifactual, a result of differential mortality in a setting characterized by high drop-out rates. Two categories of students were interviewed: “movers,” students who had trained in more than one school, and “quitters,” students who had terminated their training, for any reason. These students were compared with “stayers” from an earlier study. Our results are consistent with the opposite effects of traditional and modern martial arts training on aggressiveness. Further, the data generally support the training hypothesis as against selection.     

绝对音高者对音乐的加工及其神经机制

绝对音高感是一种特殊的音高命名能力。通过论述绝对音高能力与音乐加工的关系,发现绝对音高者具有对音高、音程和旋律的加工优势,但他们对相对音高的加工存在劣势。同时,与非绝对音高者相比,绝对音高者大脑结构和功能都表现出特殊性。未来研究应进一步厘清音乐训练对绝对音高者音乐加工的影响。     

临床专科医生培养模式探讨

毕业后医学教育是医学教育过程中一个非常重要且必不可少的组成部分。我国的医学教育体制中没有完备的毕业后医学教育层次。随着医学模式的转变以及人民大众医疗卫生保健服务需求的急剧变化,这一缺陷的弊端日益凸显。目前在我国医学教育中增加毕业后医学教育的条件已经基本具备。可采取多种途径实施该层次教育。     

志愿者安宁疗护知信行及培训需求调查研究

通过“志愿者安宁疗护知信行和培训需求测量量表”,抽样调查和比较社会志愿者和大学生志愿者对安宁疗护的知信行和培训需求状况。发现志愿者对安宁疗护知识的总体掌握较好,但实践参与少(仅占22.3%),且行为得分不高[(20.93±4.26)分];态度平均(74.54±8.58)分,其中社会志愿者更积极;志愿者培训需求迫切但资源可及性差,需求最高的是沟通方法和技巧、国内外经验和做法、灵性关怀和身体症状管理。亟需构建专业化的志愿者培训体系,靶向开展多元化的理论和技能培训,引导志愿者积极参与安宁疗护实践,提升团队协作服务能力。
