Experiment-based voice parades often result in low hit-rates and high false-alarm rates. One contributing factor may be that the experimental procedures omit elements that might naturally occur in the memory formation process, such as the process of reflection. In Experiment 1 (N = 180, F = 92) we explored if a post-encoding reflection manipulation, compared to a simple attention control task, prior to a five-minute retention interval would improve identification performance. In Experiment 2 (N = 180, F = 93), we explored how the effects of this manipulation might change when the retention interval was 24-h. The results show that the inclusion of a reflection manipulation did not meaningfully improve performance in either experiment. Importantly, we found no meaningful difference in performance when directly comparing the two retention interval durations. We consider theoretical explanations for these results and discuss implications for the design and validity of earwitness voice parade studies.  相似文献

Determining the number of factors in exploratory factor analysis is probably the most crucial decision when conducting the analysis as it clearly influences the meaningfulness of the results (i.e., factorial validity). A new method called the Factor Forest that combines data simulation and machine learning has been developed recently. This method based on simulated data reached very high accuracy for multivariate normal data, but it has not yet been tested with ordinal data. Hence, in this simulation study, we evaluated the Factor Forest with ordinal data based on different numbers of categories (2–6 categories) and compared it to common factor retention criteria. It showed higher overall accuracy for all types of ordinal data than all common factor retention criteria that were used for comparison (Parallel Analysis, Comparison Data, the Empirical Kaiser Criterion and the Kaiser Guttman Rule). The results indicate that the Factor Forest is applicable to ordinal data with at least five categories (typical scale in questionnaire research) in the majority of conditions and to binary or ordinal data based on items with less categories when the sample size is large.  相似文献

This study explored the core themes underlying individuals’ perceptions of their career success with the view to inform retention practices. The participants were a convenience sample of 207 employees (63% Blacks; 60% males) within a South African science and engineering company. Data were gathered by using a quantitative survey approach and posing an open-ended question to the participants regarding their perceived career success. The data were thematically analysed by using the Atlas.ti version 6 computer-aided qualitative data analysis software. Findings suggest that self-perceptions of career success are multifaceted, including learning and development; skills, experience and competence; career transitions and advancement; job content; contributing to a larger community; goal achievement; helping others; rewards and recognition; and work-life balance. Individuals’ inner definitions of career success could inform retention strategies in the science and engineering field focused on their career development, career wellbeing and satisfaction.  相似文献

This rejoinder, in response to the commentaries of Steiner, Park, and Kim (this issue) and Reshetnyak, Cham, and Hughes (this issue), discusses remaining challenges in grade retention research. First, a same-age comparison assumes that the instruments used in different grades measure ability equally well. We discuss the importance of evaluating the properties of the scaling process to address whether this assumption has been met. Second, we discuss issues in the selection of covariates to be included in the weights. Third, we discuss the unconfoundedness assumption and the problem of remaining imbalance. Finally, we provide an empirical illustration showing that studying grade-retention effectiveness comes with multiple methodological decisions that are rooted in a bias–variance trade-off.  相似文献

Weighted walking is a functional activity common in daily life and can influence risks for musculoskeletal loading, injury and falling. Much information exists about weighted walking during military, occupational and recreational tasks, but less is known about strategies used to accommodate to weight carriage typical in daily life. The purposes of the study were to examine the effects of weight carriage on kinematics and peak ground reaction force (GRF) during walking, and explore relationships between these variables. Twenty subjects walked on a treadmill while carrying 0, 44.5 and 89 N weights in front of the body. Peak GRF, sagittal plane joint/segment angular kinematics, stride length and center of mass (COM) vertical displacement were measured. Changes in peak GRF and displacement variables between weight conditions represented accommodation. Effects of weight carriage were tested using analysis of variance. Relationships between peak GRF and kinematic accommodation variables were examined using correlation and regression. Subjects were classified into sub-groups based on peak GRF responses and the correlation analysis was repeated. Weight carriage increased peak GRF by an amount greater than the weight carried, decreased stride length, increased vertical COM displacement, and resulted in a more extended and upright posture, with less hip and trunk displacement during weight acceptance. A GRF increase was associated with decreases in hip extension (|r| = .53, p = .020) and thigh anterior rotation (|r| = .57, p = .009) displacements, and an increase in foot anterior rotation displacement (|r| = .58, p = .008). Sub-group analysis revealed that greater GRF increases were associated with changes at multiple sites, while lesser GRF increases were associated with changes in foot and trunk displacement. Weight carriage affected walking kinematics and revealed different accommodation strategies that could have implications for loading and stability.  相似文献

NGO-based and rigorously monitored development programmes are bringing about important and positive socio-economic changes in the developing world. However, there are numerous instances of the employment of aggressive and grueling monitoring techniques which objectify the subject of development, the primary stakeholder, claiming development results as the successful achievement of goals of the donor or implementing organization. It is in this context that one can speak of an ethic of monitoring development programmes. The paper argues that such an ethic can be positively based on principles like empowering people through development work without hurting their sense of self-worth, the principle of trust and partnership and, negatively, never striving to objectify any person or people for the achievement of some objective, even if this objective is in itself honourable and desirable. The paper contends that if development is freeing the subject, the central player, to exercise their capability to live their life to the fullest, then development monitoring and development work in general has to enhance freedom, autonomy and openness.  相似文献

本文以社会心理研究的不同学科取向、文化取向和方法论取向做为三条主要线索,对当代社会心理学发展的多元化道路和整合社会心理学的努力进行了分析评价。认为社会心理学发展的多元化道路主要是由于社会心理的多质性和社会心理学的边缘学科性质所决定的,社今心理学发展过程中的整合努力则主要是由于社会心理的整体性和社会心理学的学科统一性所决定的。分化与整合作为当代社会心理学研究和发展的一对予盾统一体,伴随了社会心理学发展的百年进程,推动着当代社会心理学新的发展。  相似文献

研究生的科研选题的意义是十分重要的,除了作为培养未来的科研人才的一条有效途径以外,研究生的科研方向代表着目前各研究领域的最基础部分,但是,由于学生自身的各种主观因素以及学校和社会的多种客观因素导致了目前的局面:只有好的愿望达不到好的目的。要推动整个社会的科技进步,需要更深入更长远对人才的培养问题进一步思考。  相似文献

摘 要:在学习中,提取失败能否产生对知识的有效学习是一个很有意义的研究课题。以事实和概念类知识为实验材料,三个实验采用经典范式探讨了复杂意义条件下的提取失败后的学习效果。结果显示仅在尝试提取事实类题目失败后,促进了知识的保持和迁移;在迁移成绩上延时反馈优于即时反馈的效果。表明尝试提取复杂材料的信息失败后,知识的类型和反馈的时机决定了学习效果。  相似文献
