Do expertise and the degree of perception-action coupling affect natural anticipatory performance?

Two experiments using a temporal occlusion paradigm (the first with expert and novice participants and the second with participants of intermediate skill) were conducted to examine the capability of tennis players to predict the direction of an opponent's service in situ. In both experiments two different response conditions, reflecting differing degrees of perception-action coupling, were employed. In a coupled condition players were required to make a movement-based response identical to that which they would use to hit a return of service in a game situation, whereas in an uncoupled condition a verbal prediction of service direction was required. Experiment 1 provided clear evidence of superior prediction accuracy under the coupled response condition when ball flight was available, plus some limited evidence to suggest that superior prediction accuracy under uncoupled response conditions might hold true if only advance (pre-contact) information was available. Experiment 2 showed the former finding to be a robust one, but was unable to reveal any support for the latter. Experiment 1 also revealed that expert superiority is more apparent for predictions made under natural (coupled) than uncoupled response-mode conditions. Collectively, these findings suggest that different perceptual processes may be in operation in anticipatory tasks which depend on skill level, the type of information presented, and degree of perception-action coupling inherent in the task requirements.     

But I can’t pass that far! The influence of motor skill on decision making

Objectives

The influence of motor skill on perceptual-cognitive and perceptual-motor decision making has been theorised but not verified empirically.

Method

Expert (n = 19), developmental (n = 20), and lesser-skilled netballers (n = 19) completed tests designed to evaluate three different components of domain-specific expertise: (i) motor skill-execution; (ii) perceptual-cognitive decision making; and (iii) perceptual-motor decision making.

Results

Each of the three measures was found to improve commensurate with domain-specific skill. Decisions requiring movements (perceptual-motor) elicited more accurate decision making than simple verbal responses (perceptual-cognitive), irrespective of participant skill. Although motor skill was found to be related to the successful execution of a most appropriate movement in a game situation, it was not found to limit the nature of the decision made by participants. No evidence was found to support the supposition that lesser-skilled participants bias their perceptual-cognitive decisions towards ones supported by their motor ability.

Conclusions

Results fail to comprehensively support the contemporary models for the development of perceptual-cognitive and perceptual-motor skill in sport.     

How do world-class cricket batsmen anticipate a bowler's intention?

Four experiments are reported that examine the ability of cricket batsmen of different skill levels to pick up advance information to anticipate the type and length of balls bowled by swing and spin bowlers. The information available upon which to make the predictive judgements was manipulated through a combination of temporal occlusion of the display and selective occlusion or presentation of putative anticipatory cues. In addition to a capability to pick up advance information from the same cues used by intermediate and low-skilled players, highly skilled players demonstrated the additional, unique capability to pick up advance information from some specific early cues (especially bowling hand and arm cues) to which the less skilled players were not attuned. The acquisition of expert perceptual-motor skill appears to involve not only refinement of information extraction but also progression to the use of earlier, kinematically relevant sources of information.     

Action specificity increases anticipatory performance and the expert advantage in natural interceptive tasks

The relationship between perception-action coupling and anticipatory skill in an interceptive task was examined using an in-situ temporal occlusion paradigm. Skilled and novice cricket batsmen were required to predict the direction of balls bowled towards them under four counterbalanced response conditions of increasing perception-action coupling: (i) verbal, (ii) lower-body movement only, (iii) full-body movement (no bat), and (iv) full-body movement with bat (i.e., the usual batting response). Skilled but not novice anticipation was found to improve as a function of coupling when responses were based on either no ball-flight, or early ball-flight information, with a response requiring even the lowest degree of body movement found to enhance anticipation when compared to a verbal prediction. Most importantly, a full-body movement using a bat elicited greater anticipation than an equivalent movement with no bat. This result highlights the important role that the requirement and/or opportunity to make bat-ball interception may play in eliciting skill differences for anticipation. Results verify the importance of using experimental conditions and task demands that closely reflect the natural performance environment in order to reveal the full nature of the expert advantage.     

Evidence of mnemonic ability selectively affecting truthful and deceptive response dynamics

In the executive model of deception, the telling of a lie necessitates the inhibition of a veridical prepotent response (the truth), and such inhibition incurs a temporal penalty, manifest as a longer response time. If memory processes are engaged in generating such truths, then memory function should affect truthful and deceptive response times. To investigate this we examined the relationship between performance on a semantic knowledge deception task and a test of verbal memory in 40 college students. We found that verbal memory performance differentially affects the temporal parameters of truth and deception.     

Girls & Women Rock: Celebrating 35 Years of Sport & Title IX March 28–31, 2007

Fifty-seven female netballers completed a training history profile to examine whether the achievement of performance milestones and/or accumulation of sport-specific practice were indicative of an athlete's level of expertise. Similar to previous research, results revealed that expert and developmental athletes accumulated a greater number of hours in netball-specific practice relative to the recreational participants, but did not differ in the number of sports played or hours accumulated in non-netball specific practice. Interestingly, some performance milestones were achieved by the expert and developmental athletes earlier than the recreational participants, however, the developmental athletes achieved a number of milestones at an earlier age than the experts. These findings are discussed in relation to contemporary models of skill development, namely deliberate practice (Ericsson, Krampe, & Tesch-Römer, 1993) and the developmental model of sport participation (Côté, 1999) and the underpinning socio-environmental factors that may influence sport participation and subsequent development of expertise.     

Do interpersonal features of social anxiety influence the development of depressive symptoms?

This study is a prospective examination of possible interpersonal features of social anxiety that might predict increases in depressive symptoms. It was hypothesised that social anxiety would be associated with avoidance of expressing emotion, lack of assertion, and interpersonal dependency and that these dysfunctional interpersonal styles would predict depressive symptoms one year later while controlling for Time 1 depressive symptoms. One hundred and two undergraduates completed interview and self-report measures of these interpersonal styles in addition to measures of social anxiety and depressive symptoms. Results indicated that social anxiety was associated with all three interpersonal styles. However, only avoidance of expressing emotions predicted Time 2 depressive symptoms. Theoretical implications of these results are discussed.     

Predictors of Differential Responding on a Sentence Completion Task in Traumatized Children

Information-processing theories posit that persons who have experienced trauma may have disturbed emotional processing and therefore exhibit an excess of negative responses to otherwise neutral cues. The role of this mechanism in traumatized children has yet to be fully investigated. This study examined the relationship of varied clinical characteristics and theoretically relevant moderating variables to increased trauma related responding on a non-idiographic sentence completion task. One hundred and eighty-nine children (ages 6–17) residing at a residential home between 1996 and 2011 who had experienced physical, emotional and/or sexual abuse were administered a sentence completion task and the Trauma Symptom Checklist for Children (TSCC) shortly after their admission. Three independent raters determined whether sentence completion responses were trauma related (TRR), non-trauma related, or ambiguous. Trauma related responses were then reviewed for either avoidant/denial style responding or loss related responding. The TSCC posttraumatic stress subscale (PTS) was the only subscale that was uniquely related to TRR. A significant interaction between abuse type and PTS was found with sexual abuse moderating the effect of PTS on TRR. Additionally, age at assessment was positively correlated with both TRR and loss related responding. Time since removal from home was negatively correlated with TRR. Gender differences were found for TRR and loss related responding. These findings highlight the empirical relevance of the sentence completion task in clinical research. Results are discussed in terms of their implications for research, assessment, and intervention.     

Karl Barth on the Ascension: An Appreciation and Critique

This exposition of Barth's doctrine of the ascension in Volume IV of the Church Dogmatics –'one of the major works of ascension theology'– begins by highlighting some central themes in representative patristic and modern discussions of the ascension and then provides a close and critical reading of the Dogmatics . Of special interest are questions regarding Barth's understanding of the specificity of the Christ-event, the structure of his doctrine of reconciliation, the relation of ontology and soteriology, and the function of the doctrine of the ascension in a thoroughly a posteriori theology.
