Timing of in situ visual information pick-up that differentiates expert and near-expert anticipation in a complex motor skill

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.     

Visual span and change detection in soccer: An expertise study

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.     

Exposure to Interpersonal Violence and Socioemotional Adjustment in Economically Disadvantaged Preschoolers

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.     

Measurement Equivalence/Invariance of the Abusive Supervision Measure Across Workers From Taiwan and the United States

Growing international research interest in negative-leadership behaviors prompts the need to examine whether measures of ineffective leadership developed in the United States are equivalent across countries outside the United States. B. J. Tepper's (2000) abusive supervision measure has been used widely inside and outside the United States and merits research attention on its construct equivalence across different cultural settings. The authors conducted a series of multigroup confirmatory factor analyses to investigate the measurement equivalence of this measure across Taiwan (N = 256) and the United States (N = 389). Configural invariance was established, suggesting that both U.S. and Taiwanese samples perceive abusive supervision as a single-factor concept. Furthermore, the establishment of partial metric invariance and partial scalar invariance suggests that the abusive supervision measure is applicable to crosscultural comparisons in latent means, construct variance, construct covariances, and unstandardized path coefficients with the caution that workers from different cultures calibrate their responses differently when answering some items.     

Choosing the Appropriate Design and Analysis of a Research Project

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.     

Model of Social Competence in an Early Childhood Environment

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.     

Learning Related and Interpersonal Social Skills Constructs in Two Existing Social Skills Assessments

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.     

Using a Naturalistic Sport Context to Train Social Skills in Children

ABSTRACT

Researchers 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.     

Cognitive factors in the explanation of the mismatch between confidence and competence in performing basic life support

Abstract

The main approach to rectifying the well documented poor basic life support (BLS) skills of doctors and nurses, based on a Skills Model, has met with only partial success. This study compares the utility of a Skills Model with one that incorporates a cognitive component in predicting BLS skills. Outcome-expectancy, self-efficacy, training and experience of BLS, and BLS ability were assessed in 53 trained nurses. Ability was unrelated to training or experience of BLS. Nurses who scored highest on the BLS skills assessment perceived the procedure as significantly more successful than those with lower scores. Self-efficacy was unrelated to ability, but was related to status: senior nurses were significantly more confident but no more competent in performing BLS than junior nurses. Nurses who had attended more arrests, while more confident, were no more competent than those who had attended fewer. Assessment of BLS skills reduced self-efficacy beliefs. A model for predicting the relationship between self-assessed ability and objectively assessed skill is outlined.
