A sustained analysis of the behaviors of schooling

Educationally significant behaviors of students, teachers, and supervisors were directly assessed daily for a fiscal year in a residential school in which the results of behavior analysis research are applied to all levels of schooling. The variables assessed included those found to be concomitantly related to effective schooling as determined by the educational research literature, and functionally related to effective teaching as determined by the literature of behavior analysis. Weekly summaries of the following variables were analyzed for each of two daily shifts of teachers and supervisors: (a) number of trials presented and correct number of trials, (b) number of instructional sessions conducted, (c) number of learning objectives achieved, (d) percentage correct in each of three curricular areas, (e) weekly teacher observation scores, and (f) the total and rate per hour of supervisors' task accomplishments. There were strong positive correlations between: (a) instructional sessions and learning objectives, (b) teachers use of behavioral techniques in weekly observations by supervisors and students' achievement, (c) number of supervisor tasks completed and number of instructional sessions conducted by teachers, (d) number of teacher observations by supervisors and teachers' performance during observations, and (e) number of student objectives attained and number of tasks completed by supervisors. The assessment is the most comprehensive and sustained analysis of the daily behaviors of schooling. The relationships found between students and teacher behaviors replicate the effects of numerous experiments but do so in a total school setting. The relationships found between supervisor and student behavior have not been demonstrated in prior research. There is a need for similar school wide assessments in other types of schools to determine the generality of the relationships obtained in the present article.     

广州大学城大一大二学生颓废现象调查报告

通过对广州大学城十所高校500名大一、大二学生进行问卷调查,结果显示广州大学城大一、大二学生的颓废现象具有一定的普遍性。大学生将颓废理解为生活没有目标,无所事事,沉迷游戏、网络、电影等。大学生颓废现象主要受到学习动机、人生目标、意志等心理因素和外界因素影响,其中意志对颓废现象的影响相对较大。     

加压空心钉固定技术对比锁定钢板技术治疗桡骨远端骨折的疗效分析

对比不同手术方法对桡骨远端骨折的疗效.收集我院自2008年10月到2012年12月桡骨远端骨折患者86例,双盲随机分成试验组和对照组,试验组采用无头加压空心钉内固定,对照组采用锁定钢板内固定,比较两组的平均手术时间和平均术中出血量.术后12个月采用Jakim标准进行腕关节功能评定,同时对随访患者的腕关节功能进行临床评分.试验组平均手术时间为（30.45±5.14）min,显著低于对照组的（63.42±8.14）min（P＜0.05）,而试验组平均术中出血量为（23.67±6.14）ml,少于对照组的（83.12±10.47）ml（P＜0.05）.术后随访试验组腕关节功能优良率为87.5%;对照组则为87.1% （P＞0.05）,试验组和对照组腕关节在功能、握力活动范围等方面评分存在显著差异,在疼痛评分上两组无明显差异.采用无头加压空心钉治疗桡骨远端骨折可以显著减少手术时间及术中出血,提高腕关节功能而且在疗效上与传统锁定钢板治疗桡骨远端骨折相比无明显差异.     

基于社交媒体数据的心理指标识别建模:机器学习的方法

心理指标识别建模是基于海量数据结合计算机机器学习算法识别心理特征的一种新兴方式。由于传统纸笔测量方式所存在的诸多限制,本文对基于社交媒体数据的心理建模方法及应用于心理测量的可行性进行综述,介绍了特征及提取方法、常用机器学习算法以及应用场景,并对心理指标识别建模的优势和不足进行了总结与展望。该测量方法基于社交媒体数据,相比自我报告法具有时效性高、可回溯测量、生态效度好等独特优势。然而,基于社交媒体的心理指标识别建模方法也在学习成本、硬件成本等方面存在局限性。未来研究人员需要进一步探索社会媒体信息与用户心理变量间的关联机制,并将心理指标识别模型同传统心理学研究方法结合进行更多的探索和应用。心理指标识别建模结合心理测量基本原理和计算机领域机器学习的技术,将为心理学研究打开一扇新的大门。     

家庭功能对青少年冒险行为的影响:自我控制能力与不良同伴交往的序列中介效应

采用问卷法对922名中学生进行调查,考察了家庭功能与青少年冒险行为的关系以及自我控制能力、不良同伴交往的中介作用。结果发现:(1)家庭功能、自我控制能力、不良同伴交往和冒险行为两两之间相关显著;(2)自我控制能力在家庭功能与青少年冒险行为之间起中介作用;(3)自我控制能力和不良同伴交往在家庭功能和青少年冒险行为之间构成序列中介,家庭功能对青少年冒险行为的影响主要通过家庭功能——自我控制能力——不良同伴交往——冒险行为这一路径实现。研究结果进一步揭示了家庭、同伴和个体自身因素影响青少年冒险行为的内在机制。     

手机相关的父母教养行为与青少年手机成瘾：一项全国性调查

为考察手机使用相关的父母教养行为与青少年手机成瘾的关系以及不同手机功能使用时间的中介作用,本研究采用问卷法调查了全国8261名青少年及其家长。结果显示：（1）父母沟通和知晓均可以直接负向预测青少年手机成瘾,而父母监控直接正向预测青少年手机成瘾;（2）手机娱乐和通讯时间在父母沟通、父母监控对青少年手机成瘾的影响中产生了遮掩效应;（3）手机学习时间在父母沟通影响青少年手机成瘾中起部分中介作用。父母一定程度的行为监控、良好沟通、温暖支持有利于减少青少年手机成瘾问题。     

认知风格影响归类过程中的神经活动-来自fMRI研究的证据

行为学研究表明归类过程中的反应具有认知风格上的不同,但未有研究明确探讨归类过程的神经活动是否也受认知风格的影响。本研究通过双重认知风格分型任务筛选出分析型和整体型被试,以探讨归类过程中二者之间是否表现出神经活动的差异。实验任务要求被试从两个待选物中选出与目标物属于同一类别的一个。同时,采用fMRI技术扫描并记录他们完成任务时的BOLD信号。结果发现,与基线任务相比,整体型和分析型个体均激活了额-枕网络的一些脑区,包括额下回、楔前叶、枕中回等,表明不同认知风格个体在任务中可能共享与工作记忆等相关的脑区。另外,与分析型个体相比,整体型个体在右额下回、右旁海马回呈现更广泛的特异性激活,提示,认知风格可以影响归类过程中的脑活动,而整体型个体大脑右半球更强烈的活动表明这一类型认知风格个体在归类时更依赖于远距离的语义联结。     

Informed Decision-Making in the Context of Prenatal Chromosomal Microarray

The introduction of chromosomal microarray (CMA) into the prenatal setting has involved considerable deliberation due to the wide range of possible outcomes (e.g., copy number variants of uncertain clinical significance). Such issues are typically discussed in pre-test counseling for pregnant women to support informed decision-making regarding prenatal testing options. This research study aimed to assess the level of informed decision-making with respect to prenatal CMA and the factor(s) influencing decision-making to accept CMA for the selected prenatal testing procedure (i.e., chorionic villus sampling or amniocentesis). We employed a questionnaire that was adapted from a three-dimensional measure previously used to assess informed decision-making with respect to prenatal screening for Down syndrome and neural tube defects. This measure classifies an informed decision as one that is knowledgeable, value-consistent, and deliberated. Our questionnaire also included an optional open-ended question, soliciting factors that may have influenced the participants’ decision to accept prenatal CMA; these responses were analyzed qualitatively. Data analysis on 106 participants indicated that 49% made an informed decision (i.e., meeting all three criteria of knowledgeable, deliberated, and value-consistent). Analysis of 59 responses to the open-ended question showed that “the more information the better” emerged as the dominant factor influencing both informed and uninformed participants’ decisions to accept prenatal CMA. Despite learning about the key issues in pre-test genetic counseling, our study classified a significant portion of women as making uninformed decisions due to insufficient knowledge, lack of deliberation, value-inconsistency, or a combination of these three measures. Future efforts should focus on developing educational approaches and counseling strategies to effectively increase the rate of informed decision-making among women offered prenatal CMA.     

积极同伴压力、自尊对青少年不同冒险行为的影响

该研究基于问题行为理论,采用问卷法对普通高中、中职院校689名青少年学生进行调查,探讨了积极同伴压力、自尊对青少年不同冒险行为的影响及其交互作用和学校差异。结果表明:(1)中职院校生的积极同伴压力和冒险行为都显著高于普通高中生;(2)积极同伴压力不能预测青少年的适应不良冒险行为,但可显著预测普通高中生的社会可接受冒险行为;(3)自尊可显著负向预测青少年的适应不良冒险行为,显著正向预测普通高中生的社会可接受冒险行为;(4)自尊仅可以调节普通高中生的积极同伴压力与社会可接受冒险行为的关系:高自尊增强了高积极同伴压力对青少年社会可接受冒险行为的影响;但它不能调节无论哪所学校青少年的积极同伴压力与适应不良冒险行为的关系。
