A single bout of acute aerobic exercise has been shown to improve long-term memory, though it is unclear if exercise before learning or after learning is optimal for memory enhancement. Although some research has demonstrated that exercise before learning is ideal, investigations have consistently shown that acute arousal post-learning is a powerful memory enhancer. Therefore, the purpose of this investigation was to compare the effects of self-perceived hard cycling before or after learning on recognition memory for emotional and neutral images, and examine the relationship between central noradrenergic activity and memory performance. Seventy-two males and females (18–35 years of age) participated in this between-subjects study. Participants were randomly assigned to one of the following groups: exercise before learning, exercise after learning, and control. Participants in the exercise groups engaged in 20 min of cycling at a rating of perceived exertion (RPE) of 15 (“hard”) on the Borg RPE scale before or after viewing a series of 90 pleasant, unpleasant, and neutral images (30 each). Participants in the control group engaged in no exercise before or after image viewing. At several time points throughout the experiment, saliva was collected to measure salivary alpha amylase (sAA), a marker of central noradrenergic activity. One-week later, recognition memory was assessed where participants viewed 180 images (90 new) and had to identify which images were previously viewed. Participants in the exercise after learning group had significantly higher recognition memory compared to the control group, but this was not seen with exercise before learning. sAA was not correlated with memory in any group, though it did increase during exercise. These results demonstrate that acute self-perceived hard cycling post-learning, but not pre-learning, improves recognition memory, though this was unrelated to the exercise-induced increase in central noradrenergic activity as measured in saliva.  相似文献

Spontaneous imaginary companion (SIC) creation in childhood is a typical imaginative play behaviour associated with advanced sociocognitive skills; however, the direction of causality has not been established. To investigate this experimentally, researchers must determine whether children can create, on request, qualitatively equivalent imaginary companions (ICs) to those created spontaneously. We examined whether children could create ICs, and how these compared to SICs. Nine elementary school children were encouraged to create ICs in a 3-month intervention. Accounts of elicited ICs were compared with an age-matched sample of interviewees with SICs. Seven children maintained ICs for 6 months post intervention. Template analysis of IC interviews found four themes: Realistic Play, Multifaceted IC Mind, Utility of the IC, and Elicited IC Across Time. Analysis suggests elicited and SICs were similar in nature and utility, although intervention ICs tended to have animal rather than human appearances. Findings support the argument that children can be encouraged to create ICs similar to SICs.  相似文献

Despite widespread recognition of the importance of reflective practice in the field of infant mental health, little quantitative research exists regarding the impact of reflective supervision on professionals’ self‐efficacy, job satisfaction, and work‐related stress. Thirty‐three early childhood interventionists received approximately 9 months of reflective supervision and completed pre‐ and post‐assessments of their job‐related stress and self‐efficacy using a modified version of the Reflective Supervision Self‐Efficacy Scales for Supervisees (S. Shea, S. Goldberg, & D.J. Weatherston, 2012). At the post‐assessment, participants also rated their overall experience of reflective supervision. Reported self‐efficacy increased significantly from pre‐ to post‐assessment, and participants reported a positive overall impact of reflective supervision with respect to a variety of indices, such as job satisfaction, professional development, and the ability to cope with job‐related stress. These results provide necessary quantitative data demonstrating a positive impact of reflective supervision on early childhood professionals and suggest the value of reflective supervision for supporting workforce development.  相似文献

Objective: Perseverative cognition (e.g. worry) and unconscious stress are suggested to be important mediators in the relation between stressors and physiological health. We examined whether a smartphone-based worry-reduction training improved a physiological marker of stress (i.e. increased heart rate variability [HRV]) and unconscious stress.

Design: Randomised-controlled trial was conducted with individuals reporting work stress (n = 136). Participants were randomised to the experimental, control or waitlist condition (resp. EC, CC, WL). The EC and CC registered emotions five times daily for four weeks. The EC additionally received a worry-reduction training with mindfulness exercises.

Main Outcome Measures: Primary outcome was 24-h assessments of HRV measured at pre-, mid- and post-intervention. Secondary outcomes were implicit affect and stress. Effects on heart rate and other psychological outcomes were explored.

Results: A total of 118 participants completed the study. No change from pre- to post-intervention was observed for the primary or secondary outcomes. The change over time was not different between conditions.

Conclusion: Findings suggest that the training was ineffective for improving HRV or psychological stress. Future studies may focus on alternative smartphone-based stress interventions, as stress levels are high in society. There is need for easy interventions and smartphones offer possibilities for this.  相似文献

Objective: This study assessed the effect of a default nudge to reduce sedentary behaviour at work over time.

Design and main outcome measures: A field study was conducted at a governmental organisation. In the present study, the default setting of sit–stand desks (SSDs) was changed from sitting to standing height during a two-week intervention. Stand-up working rates were calculated based on observations that were done prior to, during, two weeks after and two months after the intervention. Additionally, a pre-measure survey (n = 606) and post-measure survey (n = 354) were completed. Intention and social norms concerning stand-up working were compared for the 183 employees who completed both pre- and post-assessments (45.4% female, Mage = 44.21).

Results: Stand-up working rates raised from 1.82% in the baseline to 13.13% during the intervention. After the nudge was removed the percentage was 10.01% after two weeks and 7.78% after two months. A multilevel analysis indicated a significant increase in both intention and social norms after the nudge intervention.

Conclusions: This study shows that a default nudge can increase stand-up working rates in offices with SSDs at least until two months after the nudge intervention.  相似文献

Autobiographical memory specificity (AMS) reduces with increasing age and is associated with depression, social problem-solving and functional limitations. However, ability to switch between general and specific, as well as between positive and negative retrieval, may be more important for the strategic use of autobiographical information in everyday life. Ability to switch between retrieval modes is likely to rely on aspects of executive function. We propose that age-related deficits in cognitive flexibility impair AMS, but the “positivity effect” protects positively valenced memories from impaired specificity. A training programme to improve the ability to flexibly retrieve different types of memories in depressed adults (MemFlex) was examined in non-depressed older adults to determine effects on AMS, valence and the executive functions underlying cognitive flexibility. Thirty-nine participants aged 70+ (MemFlex, n?=?20; control, n?=?19) took part. AMS and the inhibition aspect of executive function improved in both groups, suggesting these abilities are amenable to change, although not differentially affected by this type of training. Lower baseline inhibition scores correlated with increased negative, but not positive AMS, suggesting that positive AMS is an automatic process in older adults. Changes in AMS correlated with changes in social problem-solving, emphasising the usefulness of AMs in a social environment.  相似文献

As part of a 2-year ethnographic study, 49 adult men who had been convicted of intimate partner violence (IPV) perpetration were interviewed on what they thought would have prevented them from engaging in perpetration behaviors, or rather what they believed prevention with young boys needed to include in order to prevent future IPV perpetration. The authors’ open-ended interviews yielded five main themes: (a) messages about healthy relationship behaviors, (b) the need to promote respect for women, (c) teaching effective skills for communicating and managing anger, (d) programs that provide role models and are school-based, and (e) addressing the impact of experiencing violence as a child. The authors conclude that prevention efforts focused on changing both attitudes regarding IPV and behaviors might be most effective for reducing perpetration, and that greater attention needs to be paid towards prevention among youth most at risk of IPV perpetration, those experiencing violence in their homes.  相似文献

Adolescents with attention-deficit/hyperactivity disorder (ADHD) are at elevated risk for experiencing unipolar depressive symptoms and disorders. The current study describes the development of a behaviorally oriented depression preventive intervention tailored for adolescents with ADHD targeting variables empirically shown to mediate ADHD and depression (i.e., reward responsivity, emotion regulation, and family support). Eight adolescents with a history of ADHD and currently elevated depressive symptoms and their parents participated in an open trial of the Behaviorally Enhancing Adolescents’ Mood (BEAM) program. Adolescents and their parents reported high satisfaction with BEAM. Staff reported BEAM was easy to implement with high adherence. Following BEAM, there were significant reductions in parent-report of adolescents’ depressive symptoms and emotion regulation at posttreatment and the 6-week follow-up and adolescent-report of reward responsivity at posttreatment. Case vignettes are also provided to illustrate implementation of the BEAM program. In spite of the small sample, lack of a control group, and some discrepancies across informants, results overall support the feasibility and acceptability of the BEAM program, and suggest it has promise in reducing depressive symptoms in adolescents with ADHD.  相似文献

Clients who make repeat suicide attempts have complex needs, are at high risk of completed suicide and pose a range of challenges for clinicians. Targeted interventions are required. Acceptability, the perceived appropriateness of an intervention, is associated with successful implementation, engagement and effectiveness of interventions. Despite the advantages of group interventions, there is limited research into the acceptability of groups with this population. Using Interpretative Phenomenological Analysis, this paper reports on facilitators’ experiences (n = 9) of the acceptability of a therapeutic group intervention (PISA – a Psychoeducational/psychosocial Intervention for persons who make recurrent Suicide Attempts). Analysis of focus group data revealed how involvement with the intervention profoundly influenced facilitators’ perceptions of and approach to their work with this client group. They embraced the model, developed a deeper appreciation of clients’ resources and became unburdened from sole responsibility for the clients, the therapeutic process and outcomes. PISA provided a model that helped facilitators to work in a focused, compassionate and creative manner as they addressed the central concern of these clients, their suicidal desire, with newly found confidence and eagerness. PISA was experienced as acceptable to facilitators as it was useful to them and deemed appropriate and beneficial to the target population.  相似文献

This randomized study evaluated two evidence-based reading interventions with 121 middle school students who presented with reading fluency deficits. One intervention was teacher-directed and utilized numerous evidence-based strategies; the other intervention, the Helping Early Literacy with Practice Strategies for Small Groups Program, provided a structured implementation protocol of evidence-based strategies and specific intervention materials. Students in both groups demonstrated statistically significant growth on standardized measures of reading fluency and comprehension, but there were no differences between intervention conditions for any of the dependent measures. Practical implications for using oral reading fluency interventions at the middle school level are discussed.  相似文献
