Prospective Associations Between Sleep Disturbance and Repetitive Negative Thinking: The Mediating Roles of Focusing and Shifting Attentional Control

Although considerable evidence has linked sleep disturbance to symptoms of psychopathology, including repetitive negative thinking, few studies have examined how sleep disturbance may predict repetitive negative thinking over time. Further, no study to date has examined specific mechanisms that may account for this relationship. The present study sought to address these gaps in the literature by testing focusing and shifting attentional control as two potential mediators of the relationship between sleep disturbance and repetitive negative thinking over a 6-month period. A final sample of 445 unselected community participants completed measures of sleep disturbance and repetitive negative thinking at Time 1, measures of focusing and shifting attentional control 3 months later, and measures of repetitive negative thinking again 6 months later. Results revealed that focusing, but not shifting, attentional control mediated the relationship between sleep disturbance and repetitive negative thinking, specifically, worry, rumination, and obsessions. These findings provide preliminary evidence for focusing attentional control as a candidate mechanism that may explain the causal role of sleep disturbance in the development of repetitive negative thinking observed in various disorders.     

The role of psychological factors on the choice of different driving controls: On manual,partial, and highly automated controls

The present study investigates the role of psychological factors on the choice of three controls (modes) in driving a vehicle, namely highly automated, partially automated, and manual control. Traditional driving habits, resistance to change, and behavioural beliefs were all assessed along with individual and socioeconomic variables. Using survey data (n = 595) of car users, a model was developed to predict the share of different driving controls and determine the effects of psychological variables. Results indicate that up to 55% of people prefer driving with highly automated control, and 30% prefer partially automated control. Behavioural beliefs (e.g., attitudes toward highly automated control) are not as critical to driving control as habits. People with stronger driving habits are less likely to use highly automated controls. A one-unit increase in worry could reduce driving in highly automated control by 5.5% and increase manual control by 4.5%, and those who welcome the new technologies are more likely to prefer highly automated control. Some practical policy solutions are also provided.     

Cognitive control deployment is flexibly modulated by social value in early adolescence

Recent mechanistic models of cognitive control define the normative level of control deployment as a function of the effort cost of exerting control balanced against the reward that can be attained by exerting control. Despite these models explaining empirical findings in adults, prior literature has suggested that adolescents may not adaptively integrate value into estimates of how much cognitive control they should deploy. Moreover, much work in adolescent neurodevelopment casts social valuation processes as competing with, and in many cases overwhelming, cognitive control in adolescence. Here, we test whether social incentives can adaptively increase cognitive control. Adolescents (M_age = 14.64, 44 male, N = 87) completed an incentivized cognitive control task in which they could exert cognitive control to receive rewards on behalf of real peers who were rated by all peers in their school grade as being of either high- or low-status. Using Bayesian modeling, we find robust evidence that adolescents exert more cognitive control for high- relative to low-status peers. Moreover, we demonstrate that social incentives, irrespective of their high- or low-status, boost adolescent cognitive control above baseline control where no incentives are offered. Findings support the hypothesis that the cognitive control system in early adolescence is flexibly modulated by social value.     

父母行为控制、心理控制与高中生消极社会适应的关系：人际自立和校园排斥的序列中介作用

基于自我决定理论和人与环境互动理论,研究考察了父母行为控制、心理控制与高中生消极社会适应的关系,以及人际自立与校园排斥的中介效应。采用父母控制问卷、青少年人际自立量表、青少年校园排斥问卷、消极社会适应问卷对辽宁省3所中学的1209名高中生进行施测。结果发现:(1)父母行为控制对高中生消极社会适应无明显预测作用,心理控制对消极社会适应具有正向预测作用;(2)人际自立和校园排斥在父母控制与消极社会适应之间发挥中介作用。具体而言,父母行为控制只能通过人际自立的单独作用以及人际自立与校园排斥的序列中介作用预测高中生消极社会适应;父母心理控制既能直接预测消极社会适应,还能分别通过人际自立和校园排斥的单独作用,以及人际自立与校园排斥的序列中介作用预测高中生消极社会适应。研究最终梳理出一条“父母教养→人格发展→人际反馈→适应结果”的理论作用机制。     

客户支持对一线服务员工服务绩效的影响——基于自我验证理论的视角

基于自我验证理论, 文章探讨了客户支持能否通过组织自尊的中介作用促进员工服务绩效(角色内服务绩效和主动服务客户行为), 以及员工促进定向和内控的调节作用。针对3时间点的调查得到652名员工和139名主管的配对数据进行分析, 结果显示：(1)客户支持会显著正向影响员工组织自尊, 进而显著影响他们的角色内服务绩效和主动服务客户行为; (2)员工促进定向正向调节客户支持对员工组织自尊的影响; (3)员工内控负向调节客户支持对员工组织自尊的影响。研究结果拓展了员工服务绩效的机制研究, 为组织提升员工服务绩效提供了新的思路。     

Empirically distinguishing interpersonal styles within romantic relationships: What is helpful or harmful when having a goal for your romantic partner?

IntroductionRelationship research rooted in self-determination theory often focuses on autonomy support. However, rarely is this interpersonal style considered alongside other facets of relational behaviours such as directive support and control.ObjectiveThe present study aimed to distinguish the three styles by providing a tool that can simultaneously assess them.MethodA total sample of 710 French Canadians involved in a romantic relationship was used for factor extraction and test of dimensionality as well as reliability. Predictive validity was tested using multiple linear regressions with six outcomes: well-being, relationship quality, closeness, goal progress, cooperation and conflicts.ResultsResults suggested three distinct interpersonal styles, each of which showing a different pattern of prediction with the outcomes. Overall, autonomy support was associated with positive outcomes, whereas control was associated with negative outcomes. As for directive support, the global pattern was between the two others.ConclusionThe present research offers a scale which simultaneously assesses and distinguishes the autonomy-supportive, directive-supportive and controlling styles in a romantic relationship context using three items each. By examining the associations between these three interpersonal styles and various outcomes four months later, this study sheds light on helpful and harmful behaviours in relation to the goals people have for their romantic partner.     

儿童语言和认知（思维）发展的关系

在对幼儿从出生到３岁语言发展追踪研究和有关实验研究结果的基础上,比较、分析儿童语言和认知（思维）发展的各阶段及起作用的因素,探讨语言发展和认知发展的关系,提出以下几点看法：（１）儿童在１岁前（前语言期）的具体思维阶段有认知（有感知、记忆、表象和思维）,但还没有真正的语言。这说明语言不是先于思维,也不是所有的思维都与语言相联系。但是,人类特有的抽象思维却与语言有着密切的联系。（２）认知（思维）发展是语言发展的基础。（３）认知（思维）发展和语言发展的关系是双向的,辩证的,是复杂地交互作用的。（４）应以辩证的唯物主义的观点来看语言和认知（思维）的产生。人类所以有语言,有高度抽象概括的思维,都源于人类的实践活动。     

Dynamic dominance persists during unsupported reaching

Previous studies examining lateralization of arm movements focused on supported movements in the horizontal plane, removing the effects of gravity. The authors hypothesized that interlimb differences in free reaching would be consistent with the differences shown during supported reaching. Kinematic and kinetic data were collected for the forearm and upper arm segments in a 3-direction reaching task. Results showed lateralization of coordination, reflected by initial movement direction and trajectory curvature. The nondominant arm showed increased initial direction errors, and path curvature associated with a timing deficit between elbow and shoulder peak torques. These coordination deficits did not disrupt final position accuracy. The authors conclude that nondominant arm coordination deficits are similar to those reported previously for horizontal plane movements.     

Individual differences in reappraisal ability: Links to reappraisal frequency, well-being, and cognitive control

Reappraisal is generally viewed as an adaptive emotion regulation strategy. Reappraisal frequency has been associated with greater well-being, and reappraisal ability is thought to be composed of several crucial cognitive control processes. However, the relationships among reappraisal ability, reappraisal frequency, well-being, and various cognitive control processes have not yet been determined. In this study, we experimentally examined individual differences in reappraisal ability (RA), and also assessed reappraisal frequency, well-being, and several cognitive control processes. We observed a positive relationship between RA, reappraisal frequency, and well-being. RA was also related positively to working memory capacity and set-shifting costs, and marginally related to abstract reasoning. These findings have important implications for understanding the cognitive components and affective outcomes of RA.     

A forced-attention dichotic listening fMRI study on 113 subjects

We report fMRI and behavioral data from 113 subjects on attention and cognitive control using a variant of the classic dichotic listening paradigm with pairwise presentations of consonant-vowel syllables. The syllable stimuli were presented in a block-design while subjects were in the MR scanner. The subjects were instructed to pay attention to and report either the left or right ear stimulus. The hypothesis was that paying attention to the left ear stimulus (FL condition) induces a cognitive conflict, requiring cognitive control processes, not seen when paying attention to the right ear stimulus (FR condition), due to the perceptual salience of the right ear stimulus in a dichotic situation. The FL condition resulted in distinct activations in the left inferior prefrontal gyrus and caudate nucleus, while the right inferior frontal gyrus and caudate were activated in both the FL and FR conditions, and in a non-instructed (NF) baseline condition.
