The aim of this study was to examine action memory as a form of episodic memory among school-aged subjects. Most research on action memory has focused on memory changes in adult populations. This study explored the action memory of children over time. A total of 410 school-aged child participants, comprising 201 girls and 208 boys in four age groups (8, 10, 12, and 14), were included in this study. We studied two forms of action encoding, subject-performed tasks (SPTs) and experimenter-performed tasks (EPTs), which were compared with one verbal encoding task as a control condition. At retrieval, we used three memory tests (free recall, cued recall, and recognition). We observed significant differences in memory performance in children aged 8–14 years with respect to free recall and cued recall but not recognition. The largest memory enhancement was observed for the SPTs in the 8–14-year-old participants under all test conditions. Participants performed equally well on the free recall of SPTs and EPTs, whereas they displayed better performances on the cued recall and recognition of SPTs compared to EPTs. The strategic nature of SPTs and the distinction between item-specific information and relational information are discussed.  相似文献

This systematic review and meta-analysis examined the efficacy of adolescent cognitive–behavioral sleep interventions. Searches of PubMed, PsycINFO, CENTRAL, EMBASE, and MEDLINE were performed from inception to May 1, 2016, supplemented with manual screening. Nine trials were selected (n = 357, mean age = 14.97 years; female = 61.74%). Main outcomes were subjective (sleep diary/questionnaire) and objective (actigraphy) total sleep time (TST), sleep onset latency (SOL), sleep efficiency (SE), and wake after sleep onset (WASO). There were a small number of randomized controlled trials (RCTs; n = 4) and a high risk of bias across the RCTs; therefore, within sleep condition meta-analyses were examined (n = 221). At post-intervention, subjective TST improved by 29.47 min (95% CI 17.18, 41.75), SOL by 21.44 min (95% CI ?30.78, ?12.11), SE by 5.34% (95% CI 2.64, 8.04), and WASO by a medium effect size [d = 0.59 (95% CI 0.36, 0.82)]. Objective SOL improved by 16.15 min (95% CI ?26.13, ?6.17) and SE by 2.82% (95% CI 0.58, 5.07). Global sleep quality, daytime sleepiness, depression, and anxiety also improved. Gains were generally maintained over time. Preliminary evidence suggests that adolescent cognitive–behavioral sleep interventions are effective, but further high-quality RCTs are needed. Suggestions for further research are provided.  相似文献

The main aim of the current study is to examine the changes in the components of subjective well-being (SWB) over time in patients with osteoarthritis who have undergone total hip or knee replacement surgery (arthroplasty). We are also interested in determining whether pre-operative ratings of self-reported health (SRH) status, as well as change in health status, can serve as predictors for postoperative levels of SWB. To this end, 50 participants who had been admitted to a hospital for arthroplasty completed the measures twice—first at the clinic one day before the surgery, and then at home approximately 4.5 months after the surgery. Despite the fact that there were substantial improvements in participants’ health and physical functioning after the arthroplasty, there were no changes in their ratings of general SRH, life satisfaction (LS), or negative affect (NA). The only change in SWB scores was in the level of positive affect (PA), which was significantly higher after surgery compared with the pre-operative measurement. LS, NA, and PA scores after arthroplasty were differentially predicted by health ratings, showing that, it is the cognitive-evaluative component of SWB (i.e., LS) that is mostly responsible for the association between general SRH and SWB while affective components (i.e., NA and PA) are primarily related to more specific health indicators. Our findings can assist physicians in their efforts to provide more realistic expectations for their patients undergoing surgery in terms of the physical and psychological outcome.  相似文献

An increasing number of people have difficulties in limiting private PC/internet use. Especially, MMORP games (massively multiplayer online role-playing games) like ?World of Warcraft“, action games (?Ego-shooters“) like ?Counterstrike“, surfing and chatting are very time-consuming and for some people can reach a pathological level. When real life disappears from a person’s sight and he is almost permanently focusing on the virtual world, we speak about ?pathological PC/internet use“. The great amount of time spent online for non-work or non-school related purposes is one major symptom. In the AHG clinic Münchwies an in-patient program for pathological PC/internet users has been developed. which focuses on group therapy and is based on integrative cognitive behavioural therapy. Difficulties with motivation, compliance, interaction, attachment organisation and self-structuring of those patients are addressed in addition to the core symptoms. A major goal is to centre the patient’s activities and interests back towards real life in order to establish functioning social-interactive relationships again and to reduce the PC/internet use strictly to professional and necessary private activities.  相似文献

ABSTRACT— We examined visual search for color singleton targets, whose shape was discriminated. Critically, we varied the reward priority of singleton colors (correct fast performance was worth more bonus points for red singletons than for green singletons, or vice versa) to test whether event-related potential signatures of visual selection can be affected by distinct reward priorities for different target types, even when every target has to be selected for report. The N2pc component was earlier and larger for high- than for low-reward targets. This influence of reward on the N2pc correlated with the subject-by-subject impact of reward level on efficiency of behavioral performance. Later postselection processing was also affected by reward level. These results demonstrate that visual selection of task-relevant items is rapidly modulated by reward-related priorities, even when every target has to be selected for response.  相似文献

The enactment effect, the stable finding that memory for action phrases is enhanced in a subject-performed compared to a verbal task (SPT; VT), has repeatedly been demonstrated. The question remains whether the enactment effect has to do with specific characteristics of the SPT-retrieval process. Experiment 1 tested younger and older adults in a within-subjects design with two direct free recall tests. Thorough analyses of the recall process showed that the benefit from self-performing the items becomes apparent early into the retrieval phase for both age groups. Experiment 2 tested the same age groups with a retention phase of 30 minutes. The same general results pattern emerged. The acceleration of the recall process in SPTs is indicative of a heightened accessibility of the actively encoded material, making it less susceptible to forgetting. This property of SPTs must be taken into account when trying to determine the origins of the enactment effect.  相似文献

The relationships among conspiracy thinking and state and trait anxiety were examined with 118 high school students who were assessed using the Conspiracy Beliefs Scale and the State-Trait Anxiety Inventory. Among boys there was a positive correlation between scores on A-Trait and the conspiracy thinking (r = .39) whereas among girls there was a negative correlation between these scores (r = -.32).  相似文献

Spatially lateralised deficits that typically define the hemispatial neglect syndrome have been shown to co-occur with other non-lateralised deficits of attention, memory, and drawing. However even a simple graphic task involves multiple planning components, including the specification of drawing start position and drawing direction. In order to investigate the influence of these factors in neglect we presented patients with a circle-copying task, and specified the drawing start point. The ability to draw from the instructed location was strongly related to tests that measure constructional abilities, but not related to start point laterality. In contrast, the direction in which patients drew the circle was affected by start point laterality: patients with neglect were less likely to draw in a typical direction when the cue was on the affected side of space and this was strongly related to severity of the neglect. Patients with neglect consistently produced circles that were smaller than the model; however, the scaling was not affected by the laterality of the start point, nor was the proportion of drawings correctly started at the cue. These findings demonstrate the complex relationship between neglect and even the simplest test for the syndrome.  相似文献

Using an empowerment evaluation approach, the Sexual Assault and Rape Prevention (SARP) Evaluation Project brought together university researchers, public health evaluators, state funders, and program staff to provide evaluation training and consultation to all state-funded rape prevention and victim services programs in Michigan. In this paper, the specific activities of the SARP project are described, and process and outcome data are presented that address the effectiveness of this empowerment evaluation approach. Based on subjective reports from program staff and objective data obtained from state funders, results suggest that this evaluation model was successful in helping 90% of the prevention programs and 75% of the victim services programs successfully develop and launch program evaluations. One-year follow-up data indicate that 90% of the programs had sustained their evaluation efforts after the formal work of the SARP project had ended.  相似文献

A Swedish non-word repetition test for preschool children was constructed with the aim of measuring short-term phonological memory, which has been shown to correlate with language development and language proficiency. Normative data based on results for 200 children four to six years of age are presented. An item analysis of the original 30-item test resulted in a shortened 24 non-word version found suitable for four- to six-year old children. Results for this shortened version, which had a Cronbach's alpha of 0.73, showed longer non-words to be more difficult to repeat than shorter ones, and significant effects of age and compatibility of the tester's and the child's accent, but not of gender. The results are discussed within the framework of Baddeley's working memory model.  相似文献
