Leader–member exchange and turnover before and after succession events

We conducted two studies that investigated the role of leadership succession as a moderator of the relationship between LMX and turnover in organizations. In a sample of 330 employees in 45 veterinary hospitals, high-LMX employees were less likely to leave the organization prior to a succession event but in nine hospitals that experienced a succession event, high-LMX employees were more likely to leave than low-LMX employees following the event. In the second study, we used a between subjects repeated measures simulation of leadership succession in a survey of 496 employed adults across different organizations. We found LMX is predictive of affective and cognitive reactions to succession events, and that these reactions mediate the relationship between LMX and turnover intentions after a simulated succession event. We discuss the implications of finding that succession events can be disruptive to organizations and groups because high-LMX employees may subsequently leave.     

Context specificity in stability of hyperactivity-impulsivity

This paper exemplifies a secondary data analysis of context-specific differences in children's hyperactivity-impulsivity while controlling for informant-specific effects. Participants were boys and girls from the NICHD Study of Early Child Care and Youth Development who were measured in 1(st), 3(rd), and 5(th) grades. Latent factor models were structured using multi-informant reports including mothers, fathers, teachers, and observers. Temporal stability within a context was stronger than cross-context consistency, and the magnitude of longitudinal stability was higher in the home context compared to the school context. Controlling for informant-specific effects resulted in a significantly improved model fit and increased within-context stability. Our findings highlight the importance of considering both context and informant effects when studying longitudinal stability and change in personality development.     

Evaluating the cognitive avoidance model of generalised anxiety disorder: Impact of worry on threat appraisal, perceived control and anxious arousal

Generalised anxiety disorder (GAD) is characterised by persistent and uncontrollable worry. According to the cognitive avoidance theory of GAD, worry may function as an affective dampening strategy motivated by intolerance of negative emotional states. By facilitating avoidance of more distressing cognitions and associated affect, worry is said to preclude modification of the fear representation in memory, maintaining threat associations and perpetuating further anxiety and worry. The present study evaluated these assumptions in a treatment-seeking GAD sample. Sixty-one participants were randomly allocated to conditions in which they were instructed to worry, imaginally process or relax in response to an anxiety trigger. Results supported the detrimental impact of worry, showing maintained threat expectancies and decreased control perceptions compared to other modes of processing. However, skin conductance level increased as a function of worry and there was no suggestion that worry suppressed affective responding. These findings highlight the need for clarification of the mechanisms involved in the maintenance of threat associations and worry in GAD.     

A daily diary study of coping in the context of the job demands-control-support model

We examined one of the processes thought to underpin Karasek and Theorell’s job demands-control-support model (1990). This is that control and support accentuate better well-being by fostering problem-focused coping with work demands. We also examined whether other forms of coping implemented through control and support are related to indicators of well-being. In a daily diary study of 29 workers in a public hospital, we found higher levels of subsequent goal attainment were associated with problem-focused coping implemented by executing control. Problem-focused coping implemented by eliciting support was associated with higher concurrent and subsequent levels of pleasant affect. We found other forms of coping were also associated with affect and goal attainment. The results have implications for elaboration of the DCS model.     

Mood effects on eyewitness memory: Affective influences on susceptibility to misinformation

Does mood influence the accuracy of eyewitness recollections, and people’s susceptibility to misleading information in particular? Based on recent affect-cognition theories and research on eyewitness memory, three experiments predicted and found that positive affect promoted, and negative affect inhibited the incorporation of misleading information into eyewitness memories. This effect was obtained for both positive and negative events (Experiment 1), and for recorded as well as real-life incidents (Experiment 2). Participants had no meta-cognitive awareness of these mood effects, and affect-control instructions were ineffective in preventing them (Experiment 3). The cognitive mechanisms responsible for mood effects on eyewitness memories are discussed, and the implications of these findings for everyday memories, forensic practice and for current affect/cognition theorizing are considered.     

概念组合的理论模型

概念组合是将两个或多个概念组合成一个新概念的过程,生成的新概念被称为组合概念。组合概念的解释策略及影响因素已成为概念研究中的热点问题。研究者相继提出了关系竞争理论、双重加工理论和约束理论等模型。但是,这些理论模型只能解释特定的实验现象,对某些稳定的实验现象（如涌现特征、范畴效应等）却缺乏解释力度。文章提出,未来的研究应该整合已有的实验现象和理论模型,关注概念组合的时间进程,深入考察语境的作用,并系统地研究组合概念的涌现特征和范畴效应。     

Wayfinding with my iPhone: An autoethnographic account of technological companionship and its affects

Location-aware technologies such as GPS devices and smartphones are integral to everyday, mundane navigational practices or ‘wayfinding’. The personalisation, portability and popularity of these devices means that wayfinding can be accomplished with near-instant access to place-based information. But how do people connect to these devices in more intimate, emotional, and haptic ways? To address this question, this paper draws on autoethnographic fieldwork involving wayfinding devices, using a series of iPhone navigation apps. The paper presents a series of short narratives taken from my field diaries exploring the ways in which I perceived and performed my iPhone device as a companion during my everyday mobilities. The paper focuses on three mechanisms that facilitated relations of companionship: product design, sensory engagement and emotional/affective encounters. Building on these insights, the paper argues that relations of companionship with technological devices come into focus in particular moments when the life cycles of the users and their devices collide. The various emotions and affects, which circulate in these moments, are critical to how we make sense of space, place, and our mobilities, as well as ongoing engagements with human/technology relations.     

Affective small stories – Witnessing an ‘ideal’ instance of knowledge mobilization

In this short reflective intervention, I utilize an innovative narrative format to document my account of being an invited academic witness for the Canadian House of Commons as a graduate student. Drawing upon layered forms of critical witnessing, I utilize five small stories to consider this seemingly ideal instance of sexual health knowledge mobilization that spanned academic, government, media, and social-profit sectors. I braid complex, messy threads to capture my affective wayfinding through the complicated institutional processes involved in the generation, representation, critique and control of sexual knowledge. Highlighting how this work can be more broadly applicable to graduate students and emerging scholars in related disciplines, I note how my critical witnessing is intertwined with social, economic and political conditions present in Canada and elsewhere. This work additionally illustrates experimental self-inquiry that disrupts distinctions between researcher/subject/seer and participant/object/seen.     

Happy but overconfident: positive affect leads to inaccurate metacomprehension

When learning from text, it is important that learners not only comprehend the information provided but also accurately monitor and judge their comprehension, which is known as metacomprehension accuracy. To investigate the role of a learner’s affective state for text comprehension and metacomprehension accuracy, we conducted an experiment with N?=?103 university students in whom we induced positive, negative, or neutral affect. Positive affect resulted in poorer text comprehension than neutral affect. Positive affect also led to overconfident predictions, whereas negative and neutral affect were both associated with quite accurate predictions. Independent of affect, postdictions were rather underconfident. The results suggest that positive affect bears processing disadvantages for achieving deep comprehension and adequate prediction accuracy. Given that postdictions were more accurate, practice tests might represent an effective instructional method to help learners in a positive affective state to accurately judge their text comprehension.
