In the first experiment, refractoriness of a primary arm swing was studied using two movement speeds and three secondary responses (reversal, contralateral and ipsilateral thumb-lift). Pre-movement inter-stimulus intervals were 100, 200 or 300 msec and response-stimulus intervals ranged from zero to 200 msec. Accelerometers provided kinematic data. The second experiment repeated the reversal condition with the addition of EMG analysis.The prediction that the maximal speed condition would show a general intensification of control processes, and thus less refractoriness as compared to submaximal speed, was upheld for all response conditions. The findings also supported the prediction that the pattern of refractoriness depends on the functional relationships of the muscles concerned.The EMG analysis revealed that while the sequencing of muscle action was unchanged with movement speed, its phasing characterized the shifts in response metrics. The overall findings emphasize the need to view the refractoriness phenomenon in the context of anatomical and mechanical consequences of force changes in controlling limb movement as they interact with intentional command. 相似文献

This paper shows how a neural network can model the way people who have acquired knowledge of an artificial grammar in one perceptual domain (e.g., sequences of tones differing in pitch) can apply the knowledge to a quite different perceptual domain (e.g., sequences of letters). It is shown that a version of the Simple Recurrent Network (SRN) can transfer its knowledge of artificial grammars across domains without feedback. The performance of the model is sensitive to at least some of the same variables that affect subjects' performance—for example, the model is responsive to both the grammaticality of test sequences and their similarity to training sequences, to the cover task used during training, and to whether training is on bigrams or larger sequences. 相似文献

The predictive effects of peer victimization and harsh parenting on deliberate self-harm were examined. As derived from the experiential avoidance model, the study also tested whether these links were moderated by individual self-regulation approaches. Data were collected at two points in time from 880 junior high school students (mean age = 13.72) in Sweden. Analyses using structural equation modeling revealed that Peer Victimization was predictive of self-harm. Although Harsh Parenting was not predictive of self-harm, this link was moderated by adolescents' gender. No moderating effect of self-regulation was revealed. The study concludes that the high prevalence of deliberate self-harm recently found in community samples of adolescents cannot be prevented without attending to environmental psychosocial factors. 相似文献

Objective: This study examined the effects of age at injury on the persistence of behavior problems and social skill deficits in young children with complicated mild to severe traumatic brain injury (TBI). Method: A concurrent cohort/prospective research design was used with repeated assessments of children with TBI (n = 82) or Orthopedic Injury (OI) (n = 114). Parents completed the Child Behavior Checklist, the Behavior Rating Inventory of Executive Functions, and the Preschool and Kindergarten Behavior Scales or the Home and Community Social and Behavior Scales shortly after injury to assess preinjury functioning, and at an extended follow-up an average of 38 months postinjury. Generalized linear modeling was used to examine the relationship of age at injury to the maintenance of behavior problems, and logistic regression was used to examine the persistence of clinically significant behavior problems. Results: At the extended follow-up, severe TBI was associated with significantly greater anxiety problems relative to the Group OI. With increasing time since injury, children who sustained a severe TBI at an earlier age had significantly higher levels of parent-reported symptoms of ADHD and anxiety than children who were older at injury. Conclusions: Findings suggest that longer-term treatment for behavior problems may be needed after severe TBI, particularly for those injured at an earlier age.

Belongingness and Burdensomeness in Adolescents: Slovene Translation and Validation of the Interpersonal Needs Questionnaire 下载免费PDF全文

The Interpersonal Needs Questionnaire (INQ) for assessing thwarted belongingness (TB) and perceived burdensomeness (PB) has not been validated with community adolescents. We translated and administered the INQ to 307 Slovenian adolescents twice over 2–3 months and found that the 15‐item version (INQ‐15) did not fit without modification. TB and PB scales correlated with concurrent and later suicide ideation and lifetime suicide attempt history. The latent PB factor was associated with concurrent and later ideation controlling for TB, age, gender, depressive symptoms, binge drinking, and peer victimization. Suicide ideation and binge drinking were independently related to attempt history. Assessing and intervening on PB and binge drinking may be promising approaches to suicide prevention with community adolescents. 相似文献

Normative values for word characteristics were obtained from a sample of 12 college-educated, totally congenitally blind subjects on the basis of their ratings of 161 nouns on scales of familiarity, concreteness, meaningfulness, and imageability. The dominant modality of imagery for each image-evoking word and the strongest word associate for each item also were recorded. The same data were collected for a group of sighted subjects, both to provide a comparison group for the blind subjects and to test the comparability of sighted subjects’ ratings with existing norms. Ratings for sighted subjects correlated strongly with those norms, although the coefficients were slightly higher for ratings of concreteness and imageability than for ratings of familiarity and meaningfulness. Ratings of blind subjects correlated only slightly lower with existing norms for imagery and concreteness, but considerably lower for familiarity and meaningfulness. 相似文献

In Studies 1 and 2, the authors evaluated deliberate practice theory through analyses of the relationship between practice and performance for 2 populations of athletes: triathletes and swimmers, respectively. In Study 3, the authors obtained evaluations of practice from athletes' diaries. Across athletes, length of time involved in fitness activities was not related to performance. For the triathletes, a significant percentage of variance in performance was captured by practice. This was not so for sprint events for the swimmers, in which gender was a significant predictor. In the diaries, physical activities were perceived as enjoyable. In contrast to the results obtained from questionnaires, enjoyment did not covary with an activity's relevance to improving performance. Although these findings highlight the importance of sport-specific practice, the authors question a domain-independent account of expertise based on deliberate practice. 相似文献
