Evaluating the effectiveness of goal setting and textual feedback for increasing moderate‐intensity physical activity in adults

The purpose of this study was to evaluate the effectiveness of goal setting and textual feedback, without additional intervention components, for increasing moderate‐intensity physical activity, specifically the weekly number of intense steps measured by a Fitbit. A multiple baseline across participants design was employed with four participants using a Fitbit Flex accelerometer to measure intense steps. Results showed a substantial increase in weekly number of intense steps for three out of four participants following the intervention.     

权力何以授予：目标理论视角下领导授权行为的形成机制

随着组织所处环境的深刻变化, 如何促进管理者更加积极地表现出授权行为, 成为领导实践和研究的重要议题。现有围绕领导授权行为形成的研究存在理论基础薄弱、“以领导者为中心”倾向突出等不足, 导致其未能很好地解答现实议题。因此, 以目标理论为视角, 并整合性地考察领导者和下属的作用, 以工作团队为研究情境, 对领导授权行为的形成机制进行深入探讨。首先, 通过多案例研究, 探索出促进领导授权行为形成的目标融合类型及其作用过程, 构建出领导授权行为形成机制的理论模型; 其次, 将收集纵向的团队主管下属对子数据, 明确这些目标融合关系对领导授权行为的影响效应; 最后, 将通过进一步数据收集, 对提出的领导授权行为形成机制模型进行整体验证。这将拓宽并加深对领导授权行为形成机制的认识, 从而更好地把握领导授权行为形成的规律, 并有助于企业更好地开展与此相关的管理实践。     

助推目标实现：时间标记的动力效应

时间标记是指日常生活中所有突出的独特性事件。个体在经历当下的时间标记或期待未来的时间标记时, 其追求目标的动机水平得到提高, 并表现出更多的目标相关行为, 即时间标记具有一种动力效应。时间标记可能增加了个体对不同时间自我之间的分离感, 继而通过自我效能感、保持一致的自我形象、损失规避及缩小差距等心理过程提高追求目标的动机。未来研究应进一步探讨时间标记在动力效应中的角色定位及动力效应的持续时间、探究时间标记动力效应的普适性、检验可能的心理机制并在实践领域开展时间标记助推行为决策的应用研究。     

Motor unit firing rates of the first dorsal interosseous differ between male and female children aged 8–10 years

The purpose of this study was to examine possible differences in motor unit action potential amplitudes (MUAP_AMPS) and firing rates of the first dorsal interosseous (FDI) in male and female children aged 8–10 years. Eight male (mean ± SD, age = 8.8 ± 0.7 yrs; BMI = 16.5 ± 1.3 kg/m²) and eight female (age = 9.3 ± 0.9 yrs; BMI = 16.1 ± 1.5 kg/m²) children volunteered to complete isometric trapezoidal muscle actions of the first dorsal interosseous at 50% of maximal voluntary contraction (MVC). Electromyographic signals were decomposed to yield MUAP_AMPS and mean firing rates (MFR) at the targeted force. An exponential model was fitted to the MUAP_AMPS vs. recruitment threshold (RT) while linear models were fitted to the MFRs vs. RT relationships for each subject. Ultrasonography determined the muscle cross-sectional area (CSA) of the FDI. Independent samples t-tests were used to examine possible differences between the male and female children for MVC strength, CSA, and the coefficients from the MU relationships. There were no differences in MVC strength, CSA, or the MUAP_AMP vs. RT relationships between the male and female children (P < 0.05). Males, however, had greater MFRs of lower-threshold MUs as evident by significantly larger y-intercepts (P = 0.019) and more negative slopes (P = 0.004) from the MFR vs. RT relationships. Despite no differences in muscle strength, CSA, and MUAP_AMPS, differences in firing rates existed between male and female children aged 8–10 years. Neural mechanisms may primarily contribute to sex-related differences in firing rates.     

Developing Clear and Useful Scoring Procedures for Goal Attainment Scaling in Longitudinal Case Studies

This article examines scoring procedures for Goal Attainment Scaling (GAS) and suggests a new scoring procedure to communicate GAS outcomes in longitudinal studies. Analysis is based on longitudinal case studies that evaluate transitioning from psychiatric institutions to independent living. Five scoring methods are identified: raw scores; sum of score differences; mean scores; T-scores; and graphing raw scores. Graphing raw scores is presented as an alternative method of expressing GAS scores for studies with few participants and multiple time points. This enables easy interpretation of goal attainment, and allows for fluctuation in performance as is typical in clinical practice.     

The intergenerational transmission of authoritarianism: The mediating role of parental goal promotion

This study examined the intergenerational transmission of adolescent authoritarian submission (Right-Wing Authoritarianism or RWA) and authoritarian dominance (Social Dominance Orientation or SDO). It was hypothesized that the type of goals that parents promote (i.e., conservation versus openness to change and extrinsic versus intrinsic goal promotion) would mediate any direct association between parents’ and adolescents’ authoritarian attitudes. This hypothesis was examined in a sample of middle adolescents and their parents. First, a significant parent–child concordance was found for RWA and SDO. Second, whereas parental RWA predicted parental promotion of conservation goals (rather than openness to change goals) as well as the promotion of extrinsic goals (rather than intrinsic goals), parental SDO predicted parental promotion of extrinsic goals only. Third, process analyses showed that, whereas parental conservation goal promotion mediates the relationship between parent and child RWA, parental extrinsic goal promotion mediates the relationship between parent and child SDO.     

限制性饮食者对食物线索的注意偏向：基于目标矛盾理论模型

采用点探测变式探讨了120名成功和失败女性限制性饮食者对两类食物线索的注意偏向机制。结果发现, 当只启动享乐目标时, 成功的限制者存在对美味食物线索的注意回避, 失败的限制者存在对美味食物线索的注意脱离困难; 当相继启动享乐目标和节食目标时, 成功和失败两类限制者均存在对美味食物线索的注意回避, 但失败者仍然存在注意脱离困难。从目标矛盾模型理论对实验结果进行了讨论。     

课堂目标导向对学习成功感的影响研究

该研究以成就目标理论为指导,实证探索不同课堂目标导向对学习成功感的影响。以170名初二学生为被试,在数学课上通过不同的目标导向教学,创造出不同的目标情境,即课堂掌握目标情境、课堂成绩-趋近目标情境和课堂结合目标情境,以研究不同课堂目标导向对学生学习成功感的影响。结果表明:(1)在课堂上创造不同的目标情境具有可行性和重要性;(2)教学干预后,三个实验班学习成功感显著高于对照班;(3)经过教学干预,三个实验班学习成功感有显著提高,而对照班学习成功感前后测无显著差异。研究表明三种课堂目标情境均有助于提高学习成功感。从总体上看,研究的结果支持多重目标理论。

该文采用问卷调查的方法,对270名高中生的目标定向、学习策略、归因的特点及其与成绩的关系进行了研究。结果表明：1）男生的掌握定向倾向强于女生,且在学习中更多地采用认知和元认知策略,而女生则具有更明显的能力和内部归因。2）归因与目标定向、学习策略间呈现出较为复杂的相关关系。3）复述策略和努力归因能够负向预测成绩,调节和努力管理策略可以正向预测成绩,而目标定向通过归因和学习策略间接影响成绩。
