Community applications of instructional technology: training low-income proctors

A community education system might be most effectively implemented in low-income communities if it were deliverable by neighborhood residents. A proctor training manual, designed to teach neighborhood residents how to administer standardized learning units to their peers, was analyzed in two experiments. The results of Experiment I showed that the percentage of occurrence of proctor behaviors increased after completion of the manual. Supplementary data suggest that specified proctor behaviors generalize to actual instructional situations. The results of Experiment II showed that the percentage of occurrence of trainee behaviors was higher when instructional packages were administered by trained proctors than when administered by untrained proctors. This study demonstrates an effective procedure for training low-income community residents to serve as proctors for a community education system.     

“行高人非”还是“见贤思齐”？职场上行比较对员工行为的双刃剑效应

本研究基于压力认知评估理论,从理性认知视角探讨了职场上行比较存在的提升自我和贬损他人效应,以及驱动不同路径效应生效的边界条件和传导机制。本研究通过轮询设计,在3个时间点收集了来自60个团队240位成员的720份人际配对样本,并采用社会关系模型分析数据得出以下结论:在低水平绩效证明目标导向情况下,员工倾向于将上行比较对象评估为挑战,进而激发员工向上行比较对象的学习行为;相反,在高水平绩效证明目标导向情况下,员工倾向于将上行比较对象评估为威胁,进而驱使员工采取针对上行比较对象的社会阻抑。     

A functional analysis of personal autonomy: How restricting ‘what’, ‘when’ and ‘how’ affects experienced agency and goal motivation

Personal autonomy is central to people's experiences of agency and abilities to actively take part in society. To address the challenges of supporting autonomy, we propose a functional model of autonomy, according to which the experience of agency is a function of the opportunity to determine what to do, when to act and how to act in goal-pursuit. We tested the model in three experiments where the three goal-pursuit components could be constrained by another person or an artificial intelligence (AI) agent. Results showed that removing any of the three components from one's own decisions reduced experienced agency (Study 1a and 1b) and lowered motivation to pursue goals in organisational contexts (Study 2). In comparison to the strong and robust main effects, interactions between the components and the effects of the source of restriction (human vs. AI) were negligible. Implications for personal autonomy, algorithmic decision-making and behaviour change interventions are discussed.     

“There's more love between us”: The parental experience of attending Mellow Babies,a targeted,early intervention program for parents and their babies

It is recognized that parenthood in the context of psychosocial adversity can have negative implications for infant development. Parenting programs are the first line of intervention to improve outcomes for families; however, evidence for the effectiveness of group-based, targeted early interventions is still scarce. Preliminary findings indicate Mellow Babies (MB) as a promising group-based parenting program for families at risk for parenting difficulties. Using thematic analysis, we aimed to understand: (i) the aspects of the intervention that enabled parents to complete the program and (ii) the relational and behavioral changes perceived as valuable for parents and their babies post-intervention. In total, 68 parents residing in the United Kingdom were interviewed after completing MB (49 mothers and 19 fathers; 88% self-identified as British). Three themes and six subthemes were generated from the data. Parents identified several intervention components as beneficial, including the facilitators' interpersonal skills and multi-dimensional, group-based approach. Participant reflections highlighted three underlying mechanisms that enabled positive change: (i) the sense of community cultivated within the group, (ii) the process of formulating and re-conceptualizing one's difficulties, and (iii) the opportunity to reshape interpersonal interactions. Findings are discussed within the context of perinatal and infant mental health.     

Teaching reading and spelling: exclusion and stimulus equivalence

In Experiment 1, 7 nonreading children were exposed to a program designed to teach reading of 51 training words. The program featured an exclusion-based procedure in which the children (a) matched printed to dictated words and (b) constructed (copied) printed words with movable letters and named them. All children learned to read the training words. Five children also read generalization words and showed progress in spelling. Experiment 2 applied the program to 4 different children, omitting the word-construction task. They also learned to read the training words, but only 1 participant read generalization words. The data support a stimulus equivalence account of reading acquisition and suggest that reading generalization may be obtained, especially when the teaching program includes word construction.     

职业紧张因素的结构关系分析

运用经修订的库珀职业紧张量表对不同职业和性别的我国职工的职业紧张作了研究,发现不同职业和性别对于职务感受和个人因素解释及身体健康状况等各有显著影响,通过对量表的结构关系分析后认为目标要求、应付工作压力的策略和职工的内部控制感是影响职业紧张的深层原因。从而对现今国外有关职业紧张的理论提出了新的看法,为今后的研究与应用提供了理论根据和实践指导。     

SELF-REINFORCEMENT EFFECTS: AN ARTIFACT OF SOCIAL STANDARD SETTING?

Two studies were conducted to identify mechanisms responsible for observed "self-reinforcement" effects. In Experiment 1, using a studying task, self-reinforcement procedures did not work when they were private (i.e., when others are not aware of the goals or contingencies), but did work when they were public. Self-delivery of consequences added nothing to the effectiveness of the procedure. The data suggested that public goal setting was the critical element in the procedure's effectiveness. In Experiment 2, an applied extension, goal setting alone was effective in modifying over a long time period studying behaviors of people with significant studying difficulties, but only when the goals were known to others. Overall, the two experiments make more plausible the view that self-reinforcement procedures work by setting a socially available standard against which performance can be evaluated. The procedure itself functions as a discriminative stimulus for stringent or lenient social contingencies. The application of this mechanism to other problems of applied significance is briefly discussed.     

学生成就目标结构研究的新进展

目标激励对创业行动效能影响的情景模拟

通过情景模拟实验比较了愿景表征型目标激励与非愿景表征型目标激励对创业行动效能的影响,并且检验了成就目标导向与创业目标激励的交互作用。实验结果表明：（1）愿景表征型目标带来的激励效果显著优于非愿景表征型目标产生的激励效果。（2）目标激励与创业行动效能的关系受到成就目标导向的缓冲。（3）目标激励和成就目标导向都要通过个体感知的管理能力对创业行动效能起驱动作用。
