Understanding What’s Good for Us

The ancient question of what a good life consists in is currently the focus of intense debate. There are two aspects to this debate: the first concerns how the concept of a good life is to be understood; the second concerns what kinds of life fall within the extension of this concept. In this paper, I will attend only to the first, conceptual aspect and not to the second, substantive aspect. More precisely, I will address the preliminary, underlying question of how to understand what it is in general for something to be good for someone, from which an understanding of the more particular concept of a good life may be derived.

Effects of exercise on anxiety: A review

Abstract

The focus of this review is physical exercise and its possible effectiveness as a means of reducing anxiety. This review is based on English language literature and covers the time period from 1958 to 1988. It provides an overview of the results of research studies carried out in the area of physical fitness and psychological health, more specifically anxiety. In doing so, it draws attention to methodological limitations associated with a number of these research studies. In addition, it describes the level of exercise considered necessary to achieve improved cardio-respiratory fitness (training effect). Conclusions are made which suggest mild support for the positive effect of exercise with some individuals for reducing anxiety. Some speculative explanations as to why exercise may be effective in reducing levels of state anxiety are discussed.     

Moderate-to-vigorous intensity cycling exercise immediately after visual learning enhances delayed recognition memory performance

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.     

急性有氧运动对认知表现的影响

急性有氧运动是持续时间在10~60分钟的一次有氧运动。急性有氧运动可暂时性地改变感觉敏感度、记忆、执行功能等认知功能, 但其对不同认知功能的影响效果存在差异, 干预结果受到个体体适能水平、运动强度和运动类型等因素的调节。目前用于解释急性有氧运动影响认知表现的理论有唤醒理论、前额叶功能衰退理论、神经内分泌模型和神经营养因子假说。未来的研究应加强对急性运动发挥作用机制的探究, 更多关注身心运动、团体运动等不同运动形式的干预效果, 以期为长期“运动处方”的开具提供依据。     

TREATING SELF-INJURY: WATER MIST SPRAY VERSUS FACIAL SCREENING OR FORCED ARM EXERCISE

In three experiments, the effect of water mist spray on self-injurious and collateral behaviors was compared with either facial screening or forced arm exercise. Water mist spray was as effective as facial screening in suppressing face-slapping in Experiment 1. However, it was not as effective as facial screening for self-injurious finger-licking in Experiment 2 or forced arm exercise for excessive ear-rubbing in Experiment 3. These results suggest that while water mist spray is effective, it may be less so than alternative procedures. In Experiments 2 and 3 there was a consistent decrease in the occurrence of untreated maladaptive behaviors. In addition, there was a moderate increase in appropriate social interaction in Experiment 2 and a substantial increase in Experiment 3.     

Mixed‐methods Evaluation of the Good Behaviour Game in English Primary Schools

Inclusivity of all children in education and within educational settings is an important value and goal. Yet, where settings and practices are not oriented for inclusivity and engagement, some children can struggle with academic tasks and are often marginalised and exhibit disruptive behaviours. The study reported here addresses the social nature of school as a community for learning through a mixed‐methods concurrent triangulation evaluation of the implementation of the Good Behaviour Game (GBG) in six primary (elementary) schools with 10 classes and 222 children in Oxfordshire, England. The Teacher Observation of Classroom Adaptations ‐ Revised (TOCA‐R) was administered in individual interviews with class teachers. Additionally, individual semi‐structured interviews were conducted with teachers, coaches and head teachers (n = 22). In a pre–post design, improvements in child adaptation were observed on all TOCA‐R subscales. In an integrative analysis that brought together quantitative and qualitative findings, pupil improvement was identified in three major areas: inclusion and social participation, behaviour, and concentration. Interview results also highlighted the substantial practical challenges associated with implementing and using the GBG in schools in the UK. Overall, the results of this study support the idea that social relationships within the school community, between pupils and between pupils and teachers, provide an important context for learning and social development.

Links between religiously-focused exercise and body shape preoccupation among young adults

This quasi-experimental study examined whether engaging in physical exercise integrated with a Christian religious focus would result in decreased body shape preoccupation and improved mental and emotional health. Data were collected at the beginning and end of an eight-week period from female and male college students in three conditions: (1) group exercise sessions integrating an explicit religious focus, (2) standard group exercise, and (3) a control condition without activities. The religious exercise group decreased in body shape preoccupation to a greater extent than the control group, but the groups did not differ in other psychological symptoms or affect. This offers an initial indication that integrating a religious focus with exercise may potentially offer a unique method for addressing body shape preoccupation that is not accounted for by improvements in mental health or affect. If confirmed through additional research, infusing a religious focus into exercise regimens might inspire a practical, inexpensive method of targeting body shape dissatisfaction among young adults.     

The systematic identification of content and delivery style of an exercise intervention

Objective: This study explored the utility of using behaviour change taxonomies and checklists to systematically assess the content and delivery of behavioural support for physical activity delivered through an established exercise-referral scheme.

Design: An observation study was conducted whereby 22% of initial consultations were observed and audio-recorded, using quota sampling stratified by exercise-referral advisor.

Main outcome measures: Content was independently coded by two researchers, to assess; (i) completeness in delivering the programme protocol, (ii) behaviour change techniques delivered (defined using the CALO-RE taxonomy) and (iii) delivery style according to the Behaviour Change Counselling Index (BECCI).

Results: Protocol completeness was 63.6% (range 35.6–74.6%). The behaviour change techniques delivered most consistently were ‘providing information about where and when to perform the behavior’ (86%) and ‘setting outcome goals’ (82%). Other evidence-based techniques such as self-monitoring were infrequently observed. Variation in BECCI scores indicated that advisors could, but did not consistently, provide a client-centred service.

Conclusion: This study highlights how theoretically informed taxonomies can be useful in evaluating service delivery within applied practice, providing a meaningful way of assessing the completeness of protocol delivery relative to evidence. The provision of feedback to practitioners based on such objective criteria also facilitated positive academic-practitioner communication.     

Personality traits and body mass index: Modifiers and mechanisms

Objective: To identify how demographic factors (sex, age, ethnicity) modify the association between personality traits and body mass index (BMI) and to test the extent that diet and physical activity account for the personality-BMI relations.

Design: Cross-sectional study with a diverse sample (N = 5150, 50% female, 19% African American, 15% Hispanic). Participants completed a measure of the five major dimensions of personality and reported on their physical activity, diet and food intake behaviour, and height and weight.

Main Outcome Measures: BMI and obesity (BMI ≥ 30).

Results: High Neuroticism was associated with higher BMI and risk for obesity, whereas Conscientiousness and, to a lesser extent, Extraversion and Openness were protective. These associations were generally stronger among women and older participants; there was less evidence for ethnicity as a moderator. Personality had similar relations with the behavioural factors, and physical activity, diet and regular meal rhythms accounted for approximately 50% of the association between Neuroticism and Conscientiousness and BMI.

Conclusion: This study supports the links between personality traits and BMI and suggests that physical activity, more than diet, is a key factor in these associations.     

The influence of brief episodes of aerobic exercise activity,soothing music-nature scenes condition,and suggestion on coping with test-taking anxiety

This study examines the influence of aerobic exercise activity, soothing musicnature scenes condition, and suggestion on coping with test-taking anxiety. Sixty test anxious subjects were randomly assigned to four treatment groups consisting of 15-min episodes of exercise or soothing music-nature scenes condition with or without verbal suggestion that the treatment task in which they were engaged would be helpful to them. A videotaped intelligence test used to stimulate test-taking anxiety was given to the subjects after the soothing music-nature scenes condition or exercise tasks. The Multiple Affect Adjective Checklist (MAACL) was used to appraise anxiety during the laboratory procedures. Results indicate that exercise, soothing music-nature scenes condition, and suggestion play a role in reducing anxiety. While relaxation activity proved to be superior to exercise in reducing anxiety immediately following the treatment episode, these differences disappear following exposure to a stressful IQ test and exercise (as well as suggestion) had a better stress inoculation effect than soothing music-nature scenes condition or no suggestion.
