Employing Self-Determination Theory (Deci & Ryan, 1985) as a theoretical framework, this study examined psychological need satisfaction and motivational regulations as predictors of psychological and behavioural outcomes in exercise referral (ER). ER patients (N?=?293; mean age 54.49) completed the measures of motivational regulations, psychological need satisfaction, health-related quality of life, life satisfaction, anxiety, depression and physical activity at entry, exit and 6 months following the end of a supervised exercise programme. Change in (Δ) intrinsic motivation during the scheme significantly predicted adherence and Δ habitual physical activity. Δ psychological need satisfaction from entry to exit significantly predicted Δ habitual physical activity from exit to 6-month follow-up. Δ psychological need satisfaction significantly predicted Δ motivational regulation and Δ psychological outcomes. Contrary to expectations, Δ self-determined regulation did not significantly predict Δ psychological outcomes during the structured part of the scheme, however, it did significantly predict Δ in psychological outcomes from exit to 6-month follow-up. These findings expand on cross-sectional research to demonstrate that psychological need satisfaction during supervised ER longitudinally predicts motivational regulation and psychological outcomes up to 6 months after a structured programme. 相似文献

Decreased memory skills have been reported in children with epilepsy. However, standardized instruments to evaluate learning and memory in children have been unavailable until recently. The present study was designed to assess memory patterns in children with epilepsy based on the California Verbal Learning Test-Children's Version (CVLT-C). The test was administered to 44 children with complex partial seizures and 21 children with generalized seizures between 8 and 13 years of age. Children in the study had been treated for epilepsy for at least 6 months, had well-controlled seizures on monotherapy, and had no evidence of anticonvulsant toxicity. Children with head injuries, learning disabilities, or hyperactivity were excluded. Test results did not reflect differences in memory performance based on seizure type. Scores for the entire sample indicated intact new learning, decreased intrusions and perseverative responses, and better short-term than long-term delayed recall. Recognition skills were stronger than long-term delayed recall skills and suggested that memory performance may be improved for these children when a multiple-choice format is available in academic settings. 相似文献

Previous studies have demonstrated that animals use multiple strategies to solve spatial tasks. We used a T-maze to examine spatial behavior in crayfish, using visual and tactile stimuli as place cues and a food-scented escape tank as reinforcement to leave the maze. In trials on a single day and across multiple days, crayfish learned to exit the maze with significantly reduced latency and with fewer turns. In addition, we examined place memory in 40-min periods with the maze closed and found that crayfish spent longer in the vicinity of a previously open exit compared to a closed exit. Probe tests were conducted using a forced-choice procedure to determine whether crayfish remembered the route out of the maze using primarily place cues or response learning. We found that approximately equal numbers of animals used each strategy, and individuals were able to switch from one strategy to the other on different test days. Males and females did not differ significantly in their performance in the place memory test, maze exit task, or probe tests. Both sexes displayed place memory for the exit location and reduced latency to exit during trials 24 h, 48 h, 72 h, and 1 week after initial training trials, suggesting that spatial memories in crayfish are relatively enduring. 相似文献

Scientists have long debated the extent to which animals can imitate. Observations of bottlenose dolphins suggest a sophisticated capacity for social imitation, but little is known about the nature of these abilities. Here, we explore the behavioral mechanisms underlying a dolphin’s ability to copy motor actions while blindfolded (i.e., wearing eyecups). When a dolphin was asked to imitate a dolphin, a human, and then another dolphin blindfolded, his accuracy remained relatively consistent across models. However, his blindfolded echolocation dramatically increased when copying a human as compared to other dolphins, suggesting he actively switched between strategies: recognizing behaviors via characteristic sounds when possible, but via echolocation for the more novel sounding behaviors of the human. Such flexibility in changing perceptual routes demonstrates that the dolphin’s imitation was not automatically elicited, but rather results from an intentional, problem-solving approach to imitation. 相似文献

Spatial visualization abilities are positively related to performance on science, technology, engineering, and math tasks, but this relationship is influenced by task demands and learner strategies. In two studies, we illustrate these interactions by demonstrating situations in which greater spatial ability leads to problematic performance. In Study 1, chemistry students observed and explained sets of simultaneously presented displays depicting chemical phenomena at macroscopic and particulate levels of representation. Prior to viewing, the students were asked to make predictions at the macroscopic level. Eye movement analyses revealed that greater spatial ability was associated with greater focus on the prediction-relevant macroscopic level. Unfortunately, that restricted focus was also associated with lower-quality explanations of the phenomena. In Study 2, we presented the same displays but manipulated whether participants were asked to make predictions prior to viewing. Spatial ability was again associated with restricted focus, but only for students who completed the prediction task. Eliminating the prediction task encouraged attempts to integrate the displays that related positively to performance, especially for participants with high spatial ability. Spatial abilities can be recruited in effective or ineffective ways depending on alignments between the demands of a task and the approaches individuals adopt for completing that task. 相似文献

We compared visual priming and comparison tasks to assess information processing of a stimulus during the first 2 s after its onset. In both tasks, a 13-ms prime was followed at varying SOAs by a 40-ms probe. In the priming task, observers identified the probe as rapidly and accurately as possible; in the comparison task, observers determined as rapidly and accurately as possible whether or not the probe and prime were identical. Priming effects attained a maximum at an SOA of 133 ms and then declined monotonically to zero by 700 ms, indicating reliance on relatively brief visuosensory (iconic) memory. In contrast, the comparison effects yielded a multiphasic function, showing a maximum at 0 ms followed by a minimum at 133 ms, followed in turn by a maximum at 240 ms and another minimum at 720 ms, and finally a third maximum at 1,200 ms before declining thereafter. The results indicate three stages of prime processing that we take to correspond to iconic visible persistence, iconic informational persistence, and visual working memory, with the first two used in the priming task and all three in the comparison task. These stages are related to stages presumed to underlie stimulus processing in other tasks, such as those giving rise to the attentional blink. 相似文献

We present neuropsychological evidence indicating that action influences spatial perception. First, we review evidence indicating that actions using a tool can modulate unilateral visual neglect and extinction, where patients are unaware of stimuli presented on one side of space. We show that, at least for some patients, modulation comes about through a combination of visual and motor cueing of attention to the affected side (Experiment 1). Subsequently, we review evidence that action‐relations between stimuli reduce visual extinction; there is less extinction when stimuli fall in the correct colocations for action relative to when they fall in the incorrect relations for action and relative to when stimuli are just associatively related. Finally, we demonstrate that action relations between stimuli can also influence the binding of objects to space, in a patient with Balint's syndrome (Experiment 2). These neuropsychological data indicate that perception–action couplings can be crucial to our conscious representation of space. 相似文献

Foreign national prisoners represent an increasingly significant and vulnerable proportion of the prison estate in England and Wales, accounting for 13% of the population in custody (Prison Reform Trust, 2010). They are ever present in the Safer Custody statistics, accounting for nearly a quarter of self-harm incidents and self-inflicted deaths (HM Inspectorate of Prisons, 2009). Recent HM Inspectorate of Prisons, 2006, HM Inspectorate of Prisons, 2007, HM Inspectorate of Prisons, 2010 and a handful of research studies outline the lack of support facing many foreign national prisoners, in terms of language problems, social and cultural isolation, family support, immigration uncertainties and diversity issues. This paper reviews the current context of the foreign national prisoner population in England and Wales, paying particular attention to their experiences, specific needs, and potential threat to their mental health from being imprisoned in a foreign country. We then offer suggestions as to how these issues can be addressed by reviewing existing initiatives and making recommendations for future research. 相似文献

This article explores waysin which narrative ideas and practices might influence supervisory relationships in counselling and psychotherapy,and questions some of the taken-for-granted assumptions implicit within counselling supervision. This paper, which represents ‘work in progress’ towards further conversations, rather than an exhaustive study,is illustrated with stories from the author'sown practice as a supervisor and trainer and educator of supervisors. 相似文献
