“…Our results corroborate findings from studies of complex movement representations (Bläsing et al, 2009; Güldenpenning et al, 2011, 2013; Weigelt et al, 2011; Land et al, 2013) and skill acquisition (Frank et al, 2013). They emphasize the role of cognitive representations and processes in action control and support the view that skill representations are based on categorical knowledge.…”

“…They emphasize the role of cognitive representations and processes in action control and support the view that skill representations are based on categorical knowledge. In this regard, our study confirms the role of cognitive processes in the control of complex human actions as proposed in frameworks such as the ideomotor approach (Koch et al, 2004; for a histoical overview of the ideo-motor principle, see Stock and Stock, 2004), the theory of event coding (TEC; Hommel et al, 2001), or the cognitive action architecture approach (CAA-A; Schack and Ritter, 2009; Land et al, 2013). …”

“…It was expected that climbers, but not non-climbers, categorized climbing holds according to the appropriate grip types. Previous studies using SDA showed that experts' cluster solutions referred to functionally structured mental representations of complex movements (Bläsing et al, 2009; Land et al, 2013) or to objects affording similar actions (e.g., Stöckel et al, 2012) representing functional action-based categories of partial actions or objects.…”

In indoor rock climbing, the perception of object properties and the adequate execution of grasping actions highly determine climbers' performance. In two consecutive experiments, effects of climbing expertise on the cognitive activation of grasping actions following the presentation of climbing holds was investigated. Experiment 1 evaluated the representation of climbing holds in the long-term memory of climbers and non-climbers with the help of a psychometric measurement method. Within a hierarchical splitting procedure subjects had to decide about the similarity of required grasping postures. For the group of climbers, representation structures corresponded clearly to four grip types. In the group of non-climbers, representation structures differed more strongly than in climbers and did not clearly refer to grip types. To learn about categorical knowledge activation in Experiment 2, a priming paradigm was applied. Images of hands in grasping postures were presented as targets and images of congruent, neutral, or incongruent climbing holds were used as primes. Only in climbers, reaction times were shorter and error rates were smaller for the congruent condition than for the incongruent condition. The neutral condition resulted in intermediate performance. The findings suggest that perception of climbing holds activates the commonly associated grasping postures in climbers but not in non-climbers. The findings of this study give evidence that the categorization of visually perceived objects is fundamentally influenced by the cognitive-motor potential for interaction, which depends on the observer's experience and expertise. Thus, motor expertise not only facilitates precise action perception, but also benefits the perception of action-relevant objects.

“…In numerous studies, mental representations of complex sport movements have been found to be dependent on expertise (e.g., Schack and Mechsner, 2006;Schütz et al, 2009;Land et al, 2013). In experts, the structure of such representations is more functional and more related to biomechanical principles than in novices.…”

To better understand the benefits of using analogy and explicit instructions, the underlying cognitive mechanism remains to be explored. The concept of chunking provides a promising approach to the cognitive mechanism of instructions and can be approximated by analyzing athletes' mental representations. The purpose of this study was to investigate the influence of analogy and explicit instructions on performance and the cognitive representations of the tennis serve in intermediate participants over the course of a 5-week training period. Junior tennis players (N = 44; M = 11.5 years) were tested on their tennis serve and, based on their initial performance and their individual error patterns, assigned to one of three groups: an analogy group (N = 15), an explicit group (N = 15), or a control group (N = 14). Their performance and their mental representation structures were assessed prior to and after the 5-week training period and again after a retention period of 14 days. Independent of group, findings demonstrated higher velocity from pretest to posttest. Participants in both the analogy and the explicit group showed enhanced accuracy over time and more functional mental representation structures. Thus, both analogy instruction and explicit instruction helped to structure mental representations in their long-term memory.

Abstract. One of most common ways to examine the quality of the patient's upper extremity (UE) function is measuring the movement's kinematic parameters during the motion. However, is it reliable to compare a patient's UE motions data with healthy people's characteristic parameters? In this paper is shown that intrapersonal coefficient of variability (CV) in angles amplitudes differs from 3.2% during elbow flexion to 52.9% during wrist abduction and CV in angular velocity differs from 22.1% during shoulder abduction to 66.3% during wrist abduction.Keywords: upper extremity, objective parameters, motion capturing system, biomechanics. IntroductionThe loss of UE function is one of the most common results after Central Nervous System (CNS) injuries It is clear that only functional and clinical subjective scales are not enough for accurate motion quality measurements and that objective methods are required. Quantitative measures of UE movement's quality can be valuable in the rehabilitation field for evaluating the quality of actual motion and recovery progress [10] which might help physicians to compare accurately healthy and pathological movement conditions in a clinical setting. The purpose of the research was to find if particular kinematic parameters of healthy participant's UE motions are reliable to compare with further experiments results with patients who have UE disability and trying to recover previous movement's conditions.
