Cognitive reappraisal reduces perceived exertion during endurance exercise

Emotion regulation may influence psychological responses to exercise. We examined whether the emotion regulation strategies, cognitive reappraisal and distraction, influenced psychological state and prefrontal cortex oxygenation during endurance exercise. Twenty-four endurance runners ran for 90 min at 75–85% maximum heart rate in three separate sessions with no instruction or with instructions to use cognitive reappraisal or distraction. Participants rated their emotional arousal, emotional valence, and perceived exertion before, every 30 min during, and after exercise. Functional near-infrared spectroscopy quantified changes in prefrontal cortex oxygenation. Participants felt lower emotional arousal and physical exertion when instructed to utilize cognitive reappraisal than when given no emotion regulation instruction. Such responses to distraction did not differ from the other conditions. Emotion regulation strategies did not influence emotional valence or prefrontal cortex oxygenation. Participants’ analytical interpretation of the cognitive reappraisal instruction could contribute to small effect sizes and limited effects. Further research should determine contexts under which emotion regulation strategies most benefit endurance exercise experience.     

The relevance of being “on the same page” to succeed as a project team: A moderated mediation model

Taking a motivational approach, this study deepens the role of team members’ shared understanding of the work to be done in a project team setting. More specifically, the goal of this study is to test a second stage moderated mediation model in which the mediating role of team members’ proactive behavior in the relationship between perceived shared understanding and team performance is moderated by team adaptability. Based on a multisource and multimethod approach, data were collected from 111 teams of undergraduate and graduate students (521 participants) participating in a project management simulation. Results support the hypothesized moderated mediation model. Indeed, the results indicate that the relationship between perceived shared understanding and team performance is mediated by proactive behavior. The results also show that the relationship between proactive behavior and team performance is moderated by team adaptability. Overall, results reveal that the indirect effect of perceived shared understanding on team performance is moderated by team adaptability, such that this indirect effect is stronger when the level of team adaptability is high. In terms of practical implications, the study highlights the importance of fostering the perception of being “on the same page” in order to motivate members to be proactive and to enhance project team performance.     

Presence,Content, and Characteristics of Memories of Individuals with Dental Phobia

Knowledge about memories of distressing events underlying fears and specific phobias is limited. This study assessed (1) the presence, content, and characteristics of memories of events that initiated or exacerbated dental anxiety levels; and (2) the relationship between dental trait anxiety and some key features of these memories. This study used a semi‐structured interview and included dental phobics (n = 42), subthreshold dental phobics (n = 41), and normal controls (n = 70). Dental phobics were more likely to report a memory underlying their anxiety than the normal controls. Moreover, dental phobics' memories were reported as more vivid, disturbing, and more intensely relived than the memories of the normal controls. Greater severity of dental trait anxiety was significantly associated with greater disturbance of patients' memories. The results suggest that memories of distressing events play a significant role in the development of dental phobia and that their characteristics are associated with severity of dental trait anxiety.

Evidence for time-based models of free recall

Is memory temporally organized? According to temporal distinctiveness models of memory, temporally isolated items should be better remembered than temporally crowded items in free recall tasks. Here, we tested this class of model by varying the temporal isolation of items either predictably (Experiment 1) or unpredictably (Experiment 2) in a free recall task. In both experiments, item recall probability increased as a function of the temporal gaps both before and after the item. The results are taken as support for temporal distinctiveness models of memory, in which items are represented and recalled in terms of their positions along a temporal dimension.     

Task-irrelevant visual motion and flicker attenuate the attentional blink

Our reduced ability to correctly report two sequentially presented targets is seen in the robust effect known as the attentional blink (AB; Raymond, Shapiro, & Arnell, 1992). One recent report (Olivers & Nieuwenhuis, 2005) strikingly reveals the AB to be virtually abolished when non-task-demanding music occurs in the background. The authors suggest that a diffuse attentional state is the mediating factor. Here, we seek to broaden the finding’s generality by determining if task-irrelevant visual motion and flicker also attenuate the AB. In our experiments, the AB task was presented together with a background field of moving dots that could moveaway from ortoward the central AB task, or flicker. In the control condition, the dots remained static. The AB was attenuated—though to different degrees—in all experimental conditions, but not in the static condition. Our findings add to the generality of the previous conclusions, and we emphasize an account based on the overallocation of attention.
