Measurement invariance in mentoring research: A cross-cultural examination across Taiwan and the U.S.

Workplace mentoring in the international context is an emerging research area with significant potential for global integration. However, although measurement equivalence is a prerequisite for examining cross-cultural differences, this assumption has yet to be examined in mentoring research. This study contributes to the mentoring literature by assessing the measurement equivalence of the Mentoring Functions Questionnaire (MFQ-9) across two diverse cultural settings, the U.S. and Taiwan. Results of a series of multi-group confirmatory factor analyses supported full configural invariance, full metric invariance, and partial scalar invariance across the two groups. These findings suggest MFQ-9 may provide acceptable comparisons and meaningful interpretations across cultures. Implications for future international mentoring research and managerial practice are discussed.     

THE FUNCTIONS OF ASSESSMENT: IMPLICATIONS FOR SELECTION AND DEVELOPMENT OF DEVICES FOR ASSESSING REPERTOIRES IN CLINICAL,EDUCATIONAL, AND OTHER SETTINGS

An attempt is made to identify the many different functions that assessment of an individual's repertoire can serve. Implications of these functions for the character of and evidence about assessment devices are suggested. The functions fall into two general groups, those which influence decisions regarding an individual learner, and those which influence policy, program development, and scientific knowledge. The first group of functions is presented in a rough chronological sequence such that they form a “behavioral assessment funnel,” beginning with functions involving broad-band assessment to identify likely persons and skill areas, and narrowing to the precise pinpointing, monitoring, and follow-up functions. The contribution of behavior analysis and behavior therapy to assessment methodology in this sequence is identified as well as the areas where more traditionally conceived methods are still useful. The second group of functions and behavioral contributions to it are then discussed.     

Determination of a behavioral transfer function: White-noise analysis of session-to-session response-ratio dynamics on concurrent VI VI schedules

Six pigeons were exposed to concurrent variable-interval schedules in which the programmed reinforcer ratios changed from session to session according to a pseudorandom binary sequence. This procedure corresponded to the stochastic identification paradigm (“white-noise experiment”) of systems theory and enabled the relation between log response ratios in the current session and log reinforcer ratios in all previous sessions to be determined. Such dynamic relations are called linear transfer functions. Both nonparametric and parametric representations of these, in the form of “impulse-response functions,” were determined for each bird. The session-to-session response ratios resulting from the session-to-session pseudorandom binary variations in reinforcer ratios were well predicted by the impulse-response functions identified for each pigeon. The impulse-response functions were well fitted by a second-order dynamic model involving only two parameters: a time constant and a gain. The mean time constant was 0.67 sessions, implying that the effects of abrupt changes in log reinforcer ratios should be 96% complete within about five sessions. The mean gain was 0.53, which was surprisingly low inasmuch as it should equal the sensitivity to reinforcement ratio observed under steady-state conditions. The same six pigeons were subjected to a similar experiment 10 months following the first. Despite individual differences in impulse-response functions between birds within each experiment, the impulse-response functions determined from the two experiments were essentially the same.     

Antecedents and outcomes of career plateaus: The roles of mentoring others and proactive personality

Although mentoring others and career plateaus are both common experiences for seasoned employees, they are rarely examined together. In this study, we considered mentoring others as an antecedent of career plateaus and emotional exhaustion and turnover intentions as outcomes of career plateaus for mentors. We also examined the moderating role of mentors' proactive personality. Results of hierarchical regression analyses based on 188 mentoring dyads indicated that career-focused mentoring alleviated both hierarchical and job content plateauing perceptions. Mentors' proactive personality moderated the relationship between career-focused mentoring and hierarchical plateauing such that the negative relationship is stronger for low proactive personality mentors. Hierarchical plateaus were positively related to mentors' emotional exhaustion and turnover intentions whereas job content plateaus only positively related to turnover intentions. Proactive personality moderated the relationship between job content plateaus and mentors' work-related attitudes such that the positive relationships were stronger for more proactive mentors. The implications and future research suggestions are discussed.     

Variation in verbal fluency: A latent variable analysis of clustering,switching, and overall performance

Verbal fluency tasks have long been used to assess and estimate group and individual differences in executive functioning in both cognitive and neuropsychological research domains. Despite their ubiquity, however, the specific component processes important for success in these tasks have remained elusive. The current work sought to reveal these various components and their respective roles in determining performance in fluency tasks using latent variable analysis. Two types of verbal fluency (semantic and letter) were compared along with several cognitive constructs of interest (working memory capacity, inhibition, vocabulary size, and processing speed) in order to determine which constructs are necessary for performance in these tasks. The results are discussed within the context of a two-stage cyclical search process in which participants first search for higher order categories and then search for specific items within these categories.     

音乐训练对大学生执行功能的影响

近年来大量研究发现音乐训练对认知能力的具有积极影响,一些理论认为音乐训练的广泛迁移效应是通过执行功能起中介作用,但音乐训练与执行功能的关系至今仍存争议。研究将执行功能分为抑制控制、工作记忆和认知灵活性三个子成分,并将抑制控制进一步细分为注意抑制和反应抑制,同时区分工作记忆中主动性控制和反应性控制两种认知过程。通过对比音乐组和控制组在执行功能各任务（Go/No-go, Stroop, AX-CPT, Task-switching）上的行为表现来系统考察音乐训练与执行功能的关系。结果表明音乐训练对执行功能不同子成分的影响具有差异性,其促进效应主要体现在抑制控制中的注意抑制和工作记忆中的主动性控制,对抑制控制中的反应抑制、工作记忆中的反应性控制和认知灵活性影响较小。     

The functional theory of human values: From intentional overlook to first acknowledgement—A reply to Schwartz (2014)

Schwartz has been aware of the Functional Theory of Values for over a decade. For the first time, Schwartz (2014) acknowledges the Gouveia theory and provides considerations based on the Gouveia, Milfont, and Guerra (2014) study. In this reply we present a historical overview of the development of the theory, noting unwarranted barriers to the publication of our work. We then address his comments, focusing on the theoretical innovations of the theory and remarking that recent refinements of Schwartz’s model were already evident in the Gouveia theory. Hypotheses tested in Gouveia et al. (2014) are also re-tested and supported with European Social Survey data using the Schwartz PVQ-21. We conclude by summarizing current projects that offer further opportunities to continue the theoretical debate.     

前临床期痴呆的认知特征：当前研究进展和未来研究展望

在这篇文章中, 我将讨论从正常老化到痴呆, 这一通常被称为痴呆前临床阶段的认知功能的转变。研究表明, 阿尔茨海默症和血管性痴呆病人在临床确诊之前的几年中, 会出现明显的认知损伤。早期最突出的损伤存在于情节记忆、加工速度以及执行功能。这些功能性损伤与神经生物学研究证实的边缘系统和新皮层区存在多重损伤是相一致的。虽然早在临床诊段之前, 病人组和控制组的平均成绩存在巨大差异, 但同时这两组测试成绩的分布在很大程度上是重叠的。寻求降低这种重叠度的方法是未来研究的一个重要任务。这有可能通过将认知的和其他指标(如基于脑的、基因的、临床的、社会的)相结合构建预测模型来实现。此外, 在未来研究中以下三方面也是急需考虑问题: (a) 找出在 前临床期间认知功能急速下降的时间点: (b) 评估从前临床到临床诊断变化速率中存在的个体差异; (c) 确定特定因素与随后发生的痴呆之间的关联强度是如何随时间向临床确诊推进而逐渐变化的。     

Does child verbal ability mediate the relationship between maternal sensitivity and later self‐regulation? A longitudinal study from infancy to 4 years

There is a need to further examine the mechanisms by which maternal sensitivity influences the development of child self‐regulation. This study investigated the role of maternal sensitivity when infants were 10 months old and child verbal ability at 18 months, in relation to various aspects of self‐regulation at 48 months, in a sample of 95 typically developing children (46.3% girls). In particular, the study examined, from a Vygotskian perspective, whether child verbal ability, as measured by receptive and expressive language, mediated the relationship between maternal sensitivity and hot and cool aspects of self‐regulation in the child. As hypothesized, maternal sensitivity predicted child verbal ability, as well as working memory, set shifting, and delay of gratification. Child receptive language predicted set shifting, inhibition, and delay of gratification. In addition, receptive language mediated the relationship between maternal sensitivity and inhibition only. Additive effects of maternal sensitivity and child receptive language in relation to set shifting were found, and a main effect of maternal sensitivity on child delay of gratification. The results add to the body of research suggesting that responsive parenting and child verbal ability are important for the development of self‐regulation, and suggest that different mechanisms may be at work for different aspects of self‐regulation.
