The authors compared the relations between general psychological difficulties and dimensions of temperament in children with and without learning disability (LD). The main aim was to analyze whether and to what extent children's temperament dimensions contribute to their general psychological difficulties when LD diagnosis, age, and gender are taken into account. Participants were 52 elementary school children 7–11 years old (M age = 8.61 years, SD = 1.21 years). Twenty-six of them had been diagnosed with LD. Six teachers rated their pupils with and without LD in relation to their general psychological difficulties (Strengths and Difficulties Questionnaire) and temperament dimensions (Italian Questionnaires of Temperament). In children with LD, the main dimensions of temperament with the power to predict general psychological difficulties (i.e., emotionality and social orientation) concern these students' relationships with others (teachers and peers). The findings of the current study draw educators' and practitioners' attention to the fact that children's temperamental characteristics may affect how they experience their LD, with significant implications for their later social adjustment. 相似文献
Crossed dominance (CD) is defined as an individual's dominant hand and dominant eye being on opposite sides of the body. CD negatively impacts an individual's ability to accurately aim and fire long-barreled guns. The authors developed and evaluated a hand dominance transfer (HDT) intervention to improve the M16 rifle shooting accuracy, efficiency, and skill transfer. Twenty-four U.S. Army soldiers with CD were taught how to handle and fire an M16 rifle using the nondominant hand. Training was conducted at a military, indoor laser-equipped weapons simulator. Accuracy for shooting 40 rounds at baseline with the nondominant eye and dominant hand (NDE/DH) was 22.12 compared to shooting 30.46 with the dominant eye and nondominant hand (DE/NDH). This difference was statistically significant with p = .000. The transfer of shooting accuracy skill (retention) following the HDT intervention was 33.42 with a comparative p value of .100. Efficiency of shooting 10 rounds at baseline with the NDE/DH was 6.3 compared to shooting 7.3 with the DE/NDH. This difference was not statistically significant (p = .107). The transfer of shooting efficiency skill (retention) was 7.96 with a comparative p value of .349. This study supports shooting with the DE/NDH. HDT could be further developed to address the soldiering skill of shooting an M16. 相似文献
The authors tested whether 2 doses of remote limb ischemic conditioning (RLIC), induced via blood pressure cuff inflation, enhanced motor and cognitive learning to an equal extent, and explored a panel of blood biomarkers of RLIC. Thirty-two young adults were randomized to 3 groups and underwent a 7-day protocol of RLIC/sham followed by motor and cognitive training, with follow-up. Both RLIC groups had greater motor learning and a trend toward greater cognitive learning compared with the sham group. RLIC at the lower inflation pressure was as effective as RLIC with the higher inflation pressure. No significant candidate blood biomarkers were found. RLIC could be a well-tolerated method to enhance learning and improve rehabilitation outcomes in people with neurological conditions. 相似文献
The theory of direct learning (D. M. Jacobs &; C. F. Michaels, 2007Jacobs, D. M., &; Michaels, C. F. (2007). Direct learning. Ecological Psychology,19,321–349.[Taylor &; Francis Online], [Web of Science ®], [Google Scholar]) has proven useful in understanding improvement in perception and exploratory action. Here the authors assess its usefulness for understanding the learning of a motor skill, bimanual tapping at a difficult phase relation. Twenty participants attempted to learn to tap with 2 index fingers at 2 Hz with a phase lag of 90° (i.e., with a right-right period of 500 ms and a right-left period of 125 ms). There were 30 trials, each with 50 tapping cycles. Computer-screen feedback informed of errors in both period and phase for each pair of taps. Participants differed dramatically in their success. Learning was assessed by identifying the succession of attractors capturing tapping over the experiment. A few participants’ attractors migrated from antiphase to 90° with an appropriate period; others became attracted to a fixed right-left interval, rather than phase, with or without attraction to period. Changes in attractor loci were explained with mixed success by direct learning, inviting elaboration of the theory. The transition to interval attractors was understood as a change in intention, and was remarkable for its indifference to typical bimanual interactions. 相似文献
In this study the levels of experienced burnout of Finnish and Chinese university students are compared using School Burnout Inventory (SBI). This study is motivated by earlier studies, which suggest that the level of student burnout is different in the culturally distinct Finnish and Chinese university systems, but which are based on different research instruments for the two groups. The sample studied consisted of 3,035 Finnish students and 2,309 Chinese students. Because of the cross‐cultural nature of this study the level of structural equivalence of SBI between the cultural groups was examined and the effect of different response styles on the results was taken into account. Both standard and robust statistical methods were used for the analyses. The results showed that SBI with two extracted components is suitable for cross‐cultural analysis between Finnish and Chinese university students. Virtually no difference was found in experienced overall burnout between the Finnish and Chinese students, which means that both university systems contain factors causing similar levels of student burnout. This study also verified that controlling for the response styles is important in cross‐cultural studies as it was found to have a distinct effect on the results obtained from mean‐level comparisons. 相似文献
This paper provides evidence for a contrastive account of explanation that is motivated by pragmatic theories that recognize the contribution that context makes to the interpretation of a prompt for explanation. This study replicates the primary findings of previous work in explanation‐based category learning (Williams & Lombrozo, 2010), extending that work by illustrating the critical role of the context in this type of learning. Participants interacted with items from two categories either by describing the items or explaining their category membership. We manipulated the feature overlap between the categories and examined both the explanations generated and acquired knowledge of the categories. Explanations for membership in a given category were influenced by the unprompted contrast category, indicating an important role for contrastive processing in the generation of explanations. The influence of the contrast category was similarly seen in the transfer performance of the participants. 相似文献
This study aimed to investigate the procedural deficit hypothesis (PDH) in children with specific language impairment (SLI) by using a mirror-drawing task, a sensorimotor adaptation paradigm that does not involve sequence learning and has never before been used in SLI. A total of 30 school-aged children with SLI matched to 30 typically developing (TD) control children had to trace several figures seen only in mirror-reversed view in two practice sessions separated by a one-week interval. Two practice conditions were compared: a constant condition in which children had to trace the same figure throughout the learning trials, and a variable one in which they had to trace different figures in each trial. The results revealed a similar learning pattern between SLI and TD children in both practice conditions, suggesting that initial learning for a non-sequential procedural task is preserved in SLI. However, the children with SLI generalized the mirror-drawing skill in the same way as the TD children only if there was variability in the way the material was trained (variable practice). No significant schedule effects were observed in the control group. 相似文献
Implicit sequence learning is thought to be preserved in aging when the to-be learned associations are first-order; however, when associations are second-order, older adults (OAs) tend to experience deficits as compared to young adults (YAs). Two experiments were conducted using a first (Experiment 1) and second-order (Experiment 2) serial-reaction time task. Stimuli were presented at a constant rate of either 800 milliseconds (fast) or 1200 milliseconds (slow). Results indicate that both age groups learned first-order dependencies equally in both conditions. OAs and YAs also learned second-order dependencies, but the learning of lag-2 information was significantly impacted by the rate of presentation for both groups. OAs showed significant lag-2 learning in slow condition while YAs showed significant lag-2 learning in the fast condition. The sensitivity of implicit sequence learning to the rate of presentation supports the idea that OAs and YAs different processing speeds impact the ability to build complex associations across time and intervening events. 相似文献
Background: Outcome research has highlighted the efficacy of internet-based cognitive behavioural therapy (iCBT). Some process research has examined users experiences of iCBT. Understanding the user experience provides valuable feedback to developers of internet-delivered interventions.
Aim: The present study aimed to evaluate user's experiences and engagement with the design features of an internet-delivered treatment programme for anxiety.
Methods: Semi-structured interviews were conducted with 7 participant users of the Space from Anxiety programme. A thematic analysis framework was employed to analyse the data collected.
Results: Identified themes related to participants engagement and adherence with the programme material, participant's experience of personal development through interaction with the programme content and participants experience of the social features employed in the programme. Another theme investigated the various attributes or conditions necessary for internet-delivered therapy to be helpful to an individual.
Conclusion: Considering the experiences of users of online interventions provides insight into what works for whom both in terms of technological features and the various skills and strategies that may compose the treatment intervention. Knowing more about what design features and strategies/components of the intervention are attractive and keep users involved can only enhance the delivery of effective internet-delivered interventions for anxiety disorders. 相似文献
