We examined age-related changes of executive functions by means of random noun generation. Consistent with previous observations on random letter generation, older participants produced more prepotent responses than younger ones. In the case of random noun generation, prepotent responses are nouns of the same category as the preceding noun. In contrast to previous observations, older participants exhibited stronger repetition avoidance and a stronger tendency toward local evenness—that is, toward equal frequencies of the alternative responses even in short subsequences. These data suggest that at higher adult age inhibition of prepotent responses is impaired. In addition, strategic attentional processes of response selection are strengthened, in particular the application of a heuristic for randomness. In this sense response selection is more controlled in older than in younger adults. 相似文献

The timing of visual information pick-up for visual anticipation was examined by comparing the capability of multiple skill groups, expert and near-expert karate athletes and novices, to block attacks using an in situ temporal occlusion paradigm. Participants stood facing a karate opponent and then attempted to block attacks (kicks and punches), whilst their vision of attacks was occluded: (a) prior to onset of opponent motion (O1), (b) after preparatory head movement (O2), and (c) after initiation of the attacking motion (O3). A no occlusion control condition provided complete vision of attacks (O4). Results revealed that expert anticipation was not significantly different to that of near-experts at O1, but was significantly different to the other group across O2–O4. Expert anticipation, however, was significantly above chance across all occlusion conditions, but near-experts performed above chance at O3 and O4, whilst novices were better than chance at O4. Unexpectedly, unique evidence was found that expert anticipation could be differentiated from near-expert anticipation in the earliest occlusion condition, where it was found that only experts were capable of using visual information from a static opponent to anticipate and block attacks above chance. The findings further understanding of expert visual anticipation to guide motor skills beyond existing expert–novice comparisons. 相似文献

Null hypothesis significance testing uses the seemingly arbitrary probability of .05 as a means of objectively determining whether a tested effect is reliable. Within recent psychological articles, research has found an overrepresentation of p values around this cut-off. The present study examined whether this overrepresentation is a product of recent pressure to publish or whether it has existed throughout psychological research. Articles published in 1965 and 2005 from two prominent psychology journals were examined. Like previous research, the frequency of p values at and just below .05 was greater than expected compared to p frequencies in other ranges. While this overrepresentation was found for values published in both 1965 and 2005, it was much greater in 2005. Additionally, p values close to but over .05 were more likely to be rounded down to, or incorrectly reported as, significant in 2005 than in 1965. Modern statistical software and an increased pressure to publish may explain this pattern. The problem may be alleviated by reduced reliance on p values and increased reporting of confidence intervals and effect sizes. 相似文献

There is evidence to suggest that sports experts are able to extract more perceptual information from a single fixation than novices when exposed to meaningful tasks that are specific to their field of expertise. In particular, Reingold et al. (2001) showed that chess experts use a larger visual span including fewer fixations when compared to their less skilled counterparts. The aim of the present study was to examine whether also in a more complex environment, namely soccer, skilled players use a larger visual span and fewer fixations than less skilled players when attempting to recognise players’ positions. To this end, we combined the gaze-contingent window technique with the change detection paradigm. Results seem to suggest that skilled soccer players do not use a larger visual span than less skilled players. However, skilled soccer players showed significantly fewer fixations of longer duration than their less skilled counterparts, supporting the notion that experts may extract more information from a single glance. 相似文献

Focusing specifically on the experiences of economically disadvantaged preschoolers, the relations between interpersonal violence exposure, behavior problems, and social skills were examined in both the home and school settings. In this racially and ethnically diverse sample of preschoolers from poor, urban households (N = 64; 3–6 years old; 56% female), many children (33%) had been exposed to at least 1 type of interpersonal violence, and even more (70%) had been exposed to any type of potentially traumatic event (PTE). Although exposure to interpersonal violence was not directly associated with parent- or teacher-reported behavior problems or social skills, a significant interaction effect was observed between exposure to interpersonal violence and teacher-reported internalizing problems in predicting teacher-reported social skills; specifically, for children with the highest levels of internalizing problems, a positive relation between interpersonal violence exposure and social skills was observed. This indirect effect was observed only in the school setting, whereas children in this high-risk sample appeared to demonstrate resilience in the home setting. Given these high rates of exposure, additional, clinically relevant research is needed to inform interventions for this vulnerable population. 相似文献

It is extremely important that the proper mental planning of a research project is considered before the data collection ever begins. Otherwise, problems may be encountered after the data have been collected and it may then be too late to correct them. This paper will explain some of the important considerations necessary in choosing an adequate design and analysis for a research project. 相似文献

Maintaining relationships and interacting socially are essential aspects of children's occupational performance. A Model of Social Competence in an Early Childhood environment has been formulated to guide the assessment of and intervention for young children with issues in social skills. This article aims to (1) present the constructs that contribute to social competence for young children, (2) describe the interrelated contextual, foundation and environmental influences on social competence using the Model of Social Competence in an Early Childhood environment as a means of systematically examining these factors, and (3) discuss future directions for early intervention for children with social competence concerns. Cultural considerations will be discussed in relation to the Singaporean early childhood context. 相似文献

In the social skills literature it has been identified that both learning related social skills and interpersonal social skills may exist. This study ascertained the views of 16 experts regarding the existence of the two proposed constructs, learning related social skills and interpersonal social skills, within two pre-existing assessments: Preschool and Kindergarten Behavior Scales–2nd edition and Child Behavior Rating Scale. Sixteen experts from Australia (n = 11) and Singapore (n = 5) with pediatric backgrounds in occupational therapy, speech pathology, psychology and early childhood education took part in the study. Experts were asked to sort cards with each of the items from the Child Behavior Rating Scale and Preschool and Kindergarten Behavior Scales–2nd edition (66 items in total) into one of two piles (one for learning related social skills and one for interpersonal social skills) and then answered several open ended questions about the clinical utility of these constructs. Preliminary evidence demonstrated the existence of the learning related social skills and interpersonal social skills constructs within the items of the two assessments (Child Behavior Rating Scale and Preschool and Kindergarten Behavior Scales–2nd edition). The experts' opinion also suggested the potential clinical benefits of assessing both learning related social skills and interpersonal social skills in preschool-age children. The study results and implications for further research and clinical practice are discussed. 相似文献

ABSTRACTResearchers have utilized sports activities to deliver social skills training (SST) programs to children. Using a multiple-baseline across behaviors design, we examined whether a brief SST program delivered during a soccer camp would increase social skills and athletic competencies. Each participant’s self-concept, and his interest in soccer were evaluated. Results suggest that the SST procedure effectively increased targeted social skills. Further, participants reported increased interest in soccer and higher overall self-concept. Our results suggest that similar effects can be achieved in a relatively short, but intense, camp that utilizes SST and sports-skill training components. Limitations and implications are discussed. 相似文献
