Meaningful patterns of activity amongst the long‐term inner city unemployed: a qualitative study

A number of studies have sought to establish the social psychological factors involved in the maintenance of active lifestyles during long‐term unemployment. The aim of this study was to describe and account for the development and maintenance of different patterns of activity, with reference to their perceived meaningfulness. This was undertaken with a sample of Birmingham's inner city, long‐term unemployed population recruited from three inner city Jobcentres, including men and women, and White, Asian and African Caribbean participants (N = 24). Interviews were conducted using a semi‐structured interview guide. Using the qualitative software program, NUD.IST, the data were analysed according to the principles of the grounded theory approach. Activities were characterized as: domestic; educational; work‐like; socializing; and none. A model of meaningful activity in the context of formal unemployment was developed. The main components of the model were: features of formal employment that inhibited participants' engagement in it; the requirements for personal meaningful activity (challenging activity, effort and commitment, and being valued by others); the consequences of meaningful activity (opportunities for self‐determination and self‐development, and achievement, competence, and confidence) and consolidating factors (social comparison, self‐appraisal, religious and political beliefs, and social support). Theories of unemployment of Jahoda, Warr, and Fryer are considered in the light of the present findings. Copyright © 2002 John Wiley & Sons, Ltd.     

Executive functioning profiles in elite volleyball athletes: Preliminary results by a sport-specific task switching protocol

Executive functions (EF) are crucial for the athletes’ success, and they are even more essential in open skill sports (e.g. volleyball and football). In these sports, due to continuously changing conditions, goal-directed behaviours need to be repeatedly adjusted and corrected. One of the most important EF is the ability to continuously switch between two different tasks being required in a random sequence. We used a task-switching protocol in elite volleyball athletes, usually playing different roles, with the aim of evaluating if each role is characterized by specific switching abilities. On the basis of the specific competences requested by the game, thirty-six elite volleyball athletes were assigned to three groups: Strikers, Defenders and Mixed. Each player completed a customized sport-specific task-switching paradigm. Data evidenced that each role has specific characteristics. In Reaction Times, the Strikers were the fastest to answer to stimuli, while the Defender group provided a worse performance, particularly when defensive actions, that probably require more cognitive elaboration, had to be processed. Different effects emerged by the Errors. In fact, the Mixed group, which was the one with more expertise, appeared to be more accurate in the responses.Although preliminary, these results showed a minimal degree of cognitive flexibility for highly specialized Strikers and a maximum level for Mixed, allowing thus to highlight specific profiles of athletes. Data observed indicate the possibility to develop a test assessing the executive domain during the recruitment in a team, revealing a useful tool for choosing the most suitable role.     

Do goal cue and motor activity impact preschoolers’ working memory?

Preschoolers are well known for their poor working memory (WM) performance. This could result from goal neglect, which would hamper the setting of maintenance strategies. Previous studies have shown that preschoolers’ WM performance can be improved in game-like tasks, because they provide cues to support goal maintenance. However, in these studies, it was unclear what features of the task (either the main toy or the motor activity required by the game) provide efficient cues. The aim of the present study was to disentangle the two features to examine cue effects in 5- to 7-year-old children. No improvement of WM performance was observed when the toy was a potential goal cue, whereas the motor activity had a detrimental effect in all age groups. The latter effect could result from a distraction of attention from attention-based maintenance activities. Hence, preschoolers' poor WM performance would not be fundamentally due to goal neglect.     

‘Habitually deciding’ or ‘habitually doing’? A response to Hagger (2019)

Hagger (2019) offers an insightful synthesis of recent theoretical and empirical developments in understanding of habit and its relevance to physical activity. This commentary extends coverage of one such advance, namely the distinction between two manifestations of habit in physical activity: habitually ‘deciding’ to engage in activity (i.e. habitual instigation), and habitually ‘doing’ the activity (habitual execution). We explore the rationale for this distinction and argue that most contemporary theory and evidence around habitual physical activity – and by extension, Hagger’s review – implicitly focuses on instigation and neglects execution. We offer hypotheses around the potential roles that habitual execution may play in physical activity. Broadening the scope of inquiry within the field to more fully encompass habitual performance would achieve a more comprehensive and informative account that incorporates concepts of skill acquisition and mastery.     

Revising Process Metaphysics in Response to Ian Barbour's Critique

In Religion in an Age of Science , Ian Barbour concludes that the contemporary evolutionary worldview with its emphasis on the interplay of law and chance, relationality and autonomy, can be properly accounted for only by something like the process-relational metaphysics of Alfred North Whitehead. At the same time, he expresses serious reservations about certain features of Whitehead's scheme, notably, his perceived inability to account for the ongoing identity of the human self and for the fact of multilevel organization within organisms and in the world of inanimate compounds. In this article, I suggest that both of these difficulties can be resolved if one adopts a revisionist understanding of the Whiteheadian category of society according to which democratically organized societies possess an ontological unity and exercise a corporate agency proper to their own level of existence and activity. Furthermore, if one applies this revisionist understanding of societies to the Whiteheadian doctrine of God, a Trinitarian understanding of God becomes possible within the overall parameters of process-relational metaphysics. In this way, traditional belief in the doctrine of the Trinity can be reconciled with a scientifically credible worldview.     

Individual Differences in Spatial Memory and Striatal ChAT Activity among Young and Aged Rats

Individual differences in spatial memory among young and aged rats were assessed using memory tasks related to integrity of the hippocampus and the neostriatum. Relationships were then examined between measures of spatial memory and regional choline acetyltransferase (ChAT) activity, a marker for cholinergic integrity. Twenty-four-month-old Long-Evans rats were impaired in comparisons with 6-month-old rats on measures of place learning, working memory, reference memory, and perseveration in water-maze tasks. Aged rats that were impaired on one measure of memory, however, were not necessarily impaired on other measures. ChAT activity in the ventromedial and dorsolateral neostriatum of aged rats was significantly reduced in comparisons with young rats whereas no difference was found in the hippocampus. Aged rats with the most ChAT activity in the anterior ventromedial neostriatum performed best on the place-learning and reference memory tasks but also made the most perseverative errors on the working memory task. In addition, young and aged rats with the most ChAT activity in the anterior dorsolateral neostriatum were those with the least accurate working memory. No relationships were found between ChAT activity in the hippocampus and spatial memory. Thus age-related memory impairment has components that can be segregated by measuring relationships between cholinergic integrity in subregions of the anterior neostriatum and memory tasks with different strategic requirements.     

Using self-determination theory to promote adolescent girls' physical activity: Exploring the theoretical fidelity of the Bristol Girls Dance Project

ObjectivesTo report the theory-based process evaluation of the Bristol Girls' Dance Project, a cluster-randomised controlled trial to increase adolescent girls' physical activity.DesignA mixed-method process evaluation of the intervention's self-determination theory components comprising lesson observations, post-intervention interviews and focus groups.MethodFour intervention dance lessons per dance instructor were observed, audio recorded and rated to estimate the use of need-supportive teaching strategies. Intervention participants (n = 281) reported their dance instructors' provision of autonomy-support. Semi-structured interviews with the dance instructors (n = 10) explored fidelity to the theory and focus groups were conducted with participants (n = 59) in each school to explore their receipt of the intervention and views on the dance instructors' motivating style.ResultsAlthough instructors accepted the theory-based approach, intervention fidelity was variable. Relatedness support was the most commonly observed need-supportive teaching behaviour, provision of structure was moderate and autonomy-support was comparatively low. The qualitative findings identified how instructors supported competence and developed trusting relationships with participants. Fidelity was challenged where autonomy provision was limited to option choices rather than input into the pace or direction of lessons and where controlling teaching styles were adopted, often to manage disruptive behaviour.ConclusionThe successes and challenges to achieving theoretical fidelity in the Bristol Girls' Dance Project may help explain the intervention effects and can more broadly inform the design of theory-based complex interventions aimed at increasing young people's physical activity in after-school settings.     

Statistical Learning Is Not Affected by a Prior Bout of Physical Exercise

This study examined the effect of a prior bout of exercise on implicit cognition. Specifically, we examined whether a prior bout of moderate intensity exercise affected performance on a statistical learning task in healthy adults. A total of 42 participants were allocated to one of three conditions—a control group, a group that exercised for 15 min prior to the statistical learning task, and a group that exercised for 30 min prior to the statistical learning task. The participants in the exercise groups cycled at 60% of their respective O₂max. Each group demonstrated significant statistical learning, with similar levels of learning among the three groups. Contrary to previous research that has shown that a prior bout of exercise can affect performance on explicit cognitive tasks, the results of the current study suggest that the physiological stress induced by moderate‐intensity exercise does not affect implicit cognition as measured by statistical learning.
