Delayed reconfiguration of a non-emotional task set through reactivation of an emotional task set in task switching: an ageing study

ABSTRACT

In our everyday life, we frequently switch between different tasks, a faculty that changes with age. However, it is still not understood how emotion impacts on age-related changes in task switching. Using faces with emotional and neutral expressions, Experiment 1 investigated younger (n?=?29; 18–38 years old) and older adults’ (n?=?32; 61–80 years old) ability to switch between an emotional and a non-emotional task (i.e. responding to the face's expression vs. age). In Experiment 2, younger and older adults also viewed emotional and neutral faces, but switched between two non-emotional tasks (i.e. responding to the face's age vs. gender). Data from Experiment 1 demonstrated that switching from an emotional to a non-emotional task was slower when the expression of the new face was emotional rather than neutral. This impairment was observed in both age groups. In contrast, Experiment 2 revealed that neither younger nor older adults were affected by block-wise irrelevant emotion when switching between two non-emotional tasks. Overall, the findings suggest that task-irrelevant emotion can impair task switching through reactivation of the competing emotional task set. They also suggest that this effect and the ability to shield task-switching performance from block-wise irrelevant emotion are preserved in ageing.     

Effects of contextual questions on experimentally induced dysphoria

In a replication and extension of Watkins, Teasdale, and Williams (2003), a scrambled sentences paradigm was used to test whether prompting contextual processing of negative cognitive primes would limit the activation of dysphoric mood. Participants were divided into two groups and, after a dysphoric mood induction procedure, were asked to unscramble sentences that either did or did not emphasise the contextual aspects of moods. Consistent with Watkins et al., participants’ despondency decreased significantly more in the contextual group than in the neutral group. This effect could not be accounted for by variations in the way sentences were unscrambled.     

Dual n-back training increases the capacity of the focus of attention

Working memory (WM) training has been reported to benefit abilities as diverse as fluid intelligence (Jaeggi et al., Proceedings of the National Academy of Sciences of the United States of America, 105:6829–6833, 2008) and reading comprehension (Chein & Morrison, Psychonomic Bulletin & Review, 17:193–199, 2010), but transfer is not always observed (for reviews, see Morrison & Chein, Psychonomics Bulletin & Review, 18:46–60, 2011; Shipstead et al., Psychological Bulletin, 138:628–654, 2012). In contrast, recent WM training studies have consistently reported improvement on the trained tasks. The basis for these training benefits has received little attention, however, and it is not known which WM components and/or processes are being improved. Therefore, the goal of the present study was to investigate five possible mechanisms underlying the effects of adaptive dual n-back training on working memory (i.e., improvements in executive attention, updating, and focus switching, as well as increases in the capacity of the focus of attention and short-term memory). In addition to a no-contact control group, the present study also included an active control group whose members received nonadaptive training on the same task. All three groups showed significant improvements on the n-back task from pretest to posttest, but adaptive training produced larger improvements than did nonadaptive training, which in turn produced larger improvements than simply retesting. Adaptive, but not nonadaptive, training also resulted in improvements on an untrained running span task that measured the capacity of the focus of attention. No other differential improvements were observed, suggesting that increases in the capacity of the focus of attention underlie the benefits of adaptive dual n-back training.     

Maternal Intergenerational Transmission of Childhood Multitype Maltreatment

Previous research suggests that child maltreatment is transmitted across familial generations. However, extant studies focused exclusively on single maltreatment subtypes, instead of the more common experience of multitype maltreatment. This limitation is addressed in the first known study to examine the maternal intergenerational transmission of childhood multitype maltreatment among 104 mothers and their children. Findings demonstrated that mothers' childhood multitype maltreatment directly predicted their children's multitype maltreatment, instead of having indirect effects through maternal romantic attachment dimension, intimate partner violence, and psychological distress. Mothers' childhood multitype maltreatment was also related to intimate partner violence and anxious romantic attachment but unrelated to psychological distress. Our findings highlight the need for clinical attention to the long-term generational effects of diverse childhood traumas.     

Group mate absence,dissimilarity, and individual absence: Another look at “monkey see,monkey do”

In this study, we examined whether the alignment of individual and group absence depended on an individual's similarity or dissimilarity with his or her group mates. The study hypotheses were tested with organizational data, involving 1382 employees from 181 work groups. Our criterion was individual absence frequency, observed over a 12-month period. Dissimilarity indices fororganizational tenure and union affiliation were computed from organizational records. We found that the relation between group mate absence and individual absence was moderated by dissimilarity with respect to union affiliation (but not tenure dissimilarity), such that those with low union dissimilarity scores were more likely to align their absence behaviour with that of their group mates.     

Imaginary Companions in Childhood: Relations to Imagination Skills and Autobiographical Memory in Adults

The presence of a childhood imaginary companion (IC) has been proposed to reflect heightened imaginative abilities. This study hypothesized that adults who reported having a childhood IC would score higher on a task requiring the imaginative construction of visual scenes. Additionally, it was proposed that individuals who produced more vivid and detailed scenes would also report richer autobiographical memories, due to a shared reliance on imaginative abilities in construction and recollection. Sixty participants (20 with an IC), completed an adapted scene construction procedure and an autobiographical memory questionnaire. Participants reporting a childhood IC scored significantly higher on scene construction and rated themselves as more imaginative. Scene construction scores were also moderately related to the richness of autobiographical memories, although this was almost entirely due to scores on the thought/emotion/action component of scene construction. Autobiographical memory was unrelated to the presence of an IC. Implications for overlapping and dissociable aspects of imagination and memory are discussed.     

Strategies Used by an Elite Curling Coach to Nurture Athletes’ Self-Regulation: A Single Case Study

Competition outcomes are a test of an athlete's ability to self-regulate; however, scant literature exists on how self-regulation processes are developed. This study investigated the strategies used by an elite curling coach to support co-regulation and help nurture his athletes’ self-regulation during a 16-week intervention involving multiple individual and group intervention sessions and interviews. The content analysis revealed that the coach utilized the following types of strategies to facilitate the athletes’ self-regulation: (a) preparatory strategies (e.g., anticipating/preparing for obstacles), (b) performance strategies (e.g., letting go of mistakes), and (c) self-reflection strategies (e.g., attributing errors to controllable aspects of performance).     

Personality,interests, and career indecision: a multidimensional perspective

Researchers have consistently linked neuroticism to career indecision; however, other personality traits have been inconsistent predictors despite sound theoretical arguments. Similarly, little research has examined a trait‐based analysis of the relationship between vocational interests and career indecision. The purpose of the current study was to evaluate the structure of career indecision and to examine the prediction of this construct as both a unidimensional and multidimensional construct. Results suggest that career indecision is multifaceted and that both personality and vocational interests are more strongly related to career indecision than has been suggested by past research. Furthermore, consideration of this multidimensional nature can explain past inconsistencies in the relationships between indecision and personality.
