“…In contrast, children whose cognitive representations were not structured by grasp comfort achieved far less satisfaction with grasp comfort in the advance planning condition. The results of the present study support the notion that cognitive action representation plays an important role in the planning and control of grasp postures (Stöckel et al, 2012).…”

“…To understand the biomechanical and cognitive background of manual action in more detail, we established lines of research on the movement primitives of manual action, with the help of biomechanical and cognitive analyses. Because the production of manual actions is affected by such factors as biomechanical constraints (Rosenbaum, Meulenbroek, Vaughan, & Jansen, 2001;Weigelt, Kunde, & Prinz, 2006), we have carried out some developmental studies on the relationship between biomechanical constraints like the end-state-comfort effect and the cognitive representation of grasping postures in children (Stöckel, Hughes, & Schack, 2012). Other studies have explored the link between semantic and motor memory, especially in the case of grasping (Weigelt, Rosenbaum, Hülshorst, & Schack, 2009).…”

a b s t r a c tTo gain a better understanding of the functionality of representation and categorization in action and interaction, it is fundamental that researchers understand how movements are represented in long-term memory. It is our position that human motor control requires that our actions be planned and represented in terms of intended perceptual effects and future task demands, and that the individual has a well-structured mental representation of the task so that the movement can be carried out successfully. Basic Action Concepts (BACs) are identified as major building blocks of cognitive representation in long-term memory, which are cognitive tools used to master the functional demands of movement tasks. In this paper, we consider relevant issues in research methodology and present an experimental method that can be used to assess action-relevant representational structures. This method permits us to observe the strong relationship between cognitive representation and performance in manual action. For example, the specific differences in the mental representations of participants are strongly related to skill level, as well as biomechanical and task constraints. We then discuss results from our learning experiments, where we have examined the development and changes in cognitive representation over time. From these experiments we have found that cognitive reference structures include task-specific spatial information, which provides the basis for action control in skilled voluntary movement. We have implemented these results on various robotic platforms. We argue that the insights gained from various experimental approaches in the field of cognitive psychology and motor control enable researchers to explore the possibilities and limitations of artificial control architectures in robot systems. Finally, we argue that this is not a unidirectional process. Researchers from the field of cognitive psychology and motor control can profit from the advances in technological systems, which enhance the understanding of human motor control in skilled voluntary action.

“…These results are in line with recent reports of typical development, where end-state comfort was comparable to adults by age 9 (Stöckel et al, 2012; Scharoun and Bryden, 2014). With respect to Hughes (1996) findings, van Swieten et al (2010) hypothesized that differences in findings are likely attributable to experimental design.…”

Autism Spectrum Disorder (ASD) is one of the most common neurodevelopmental disorders. Although not a diagnostic feature, motor impairments have been recently acknowledged as prevalent and significant, such that these children have difficulties planning, organizing and coordinating movements. This study aimed to further investigate anticipatory motor planning in children with ASD by means of assessing end- and beginning-state comfort, considering inconsistent reports of end-state comfort in independent action, and the study of beginning-state comfort being limited to one study with young adults. Five- to eleven-year-old children with ASD, and chronologically age- and sex-matched typically-developing children picked-up a glass and: (1) poured a cup of water; and (2) passed it to the researcher to pour a cup of water. End-state comfort was deemed evident if participants grasped the glass thumb-down followed by a 180° rotation; therefore ending with a thumb-up posture. Beginning-state comfort was deemed evident if participants passed the glass to the researcher oriented upright. Findings revealed less end-state comfort in children with ASD, attributed to motor planning deficits. Beginning-state comfort did not differ, ascribed to the habitual nature of the task; therefore reflecting a stimulus-driven response as opposed to an action which reflects anticipatory planning. The findings support difficulties with motor planning and control for children with ASD in an independent task. However, when acting with a familiar object in joint action, behavior does not differ, likely indicative of a habitual, stimulus-driven response.

“…The finding that end-state comfort planning was higher for the hand that could satisfy end-state comfort with an overhand grasp posture highlights the interaction of the habitual and goal-directed systems in action planning (Herbort & Butz, 2011;Stöckel, Hughes, & Schack, 2012). Specifically, when both the goal-directed and habitual systems call for an overhand grasp posture, there was no conflict between the two systems, and thus the selection of the appropriate grasp posture is facilitated.…”

The authors examined the effects of perturbations in action goal on bimanual grasp posture planning. Sixteen participants simultaneously reached for 2 cylinders and placed either the left or the right end of the cylinders into targets. As soon as the participants began their reaching movements, a secondary stimulus was triggered, which indicated whether the intended action goal for the left or right hand had changed. Overall, the tendency for a single hand to select end-state comfort compliant grasp postures was higher for the nonperturbed condition compared to both the perturbed left and perturbed right conditions. Furthermore, participants were more likely to plan their movements to ensure end-state comfort for both hands during nonperturbed trials, than perturbed trials, especially object end-orientation conditions that required the adoption of at least one underhand grasp posture to satisfy bimanual end-state comfort. Results indicated that when the action goal of a single object was perturbed, participants attempted to reduce the cognitive costs associated with grasp posture replanning by maintaining the original grasp posture plan, and tolerating grasp postures that result in less controllable final postures.
