“…The consequence of using such a method is that if responses are less vigorous, they will be considered to have occurred later in time. Other authors have also used a fixed threshold to analyse response latencies to perturbations in a grasping task with objects of different sizes and found a similar time-dependent latency (Hesse and Franz 2009; van de Kamp et al 2009). A fixed threshold would not be a problem if corrections were performed in accordance with strategy 2, because then the strength of the correction would always be the same.…”

To study the strategy in responding to target displacements during fast goal-directed arm movements, we examined how quickly corrections are initiated and how vigorously they are executed. We perturbed the target position at various moments before and after movement initiation. Corrections to perturbations before the movement started were initiated with the same latency as corrections to perturbations during the movement. Subjects also responded as quickly to a second perturbation during the same reach, even if the perturbations were only separated by 60 ms. The magnitude of the correction was minimized with respect to the time remaining until the end of the movement. We conclude that despite being executed after a fixed latency, these fast corrections are not stereotyped responses but are suited to the circumstances.

“…Paulignan, Mackenzie, Marteniuk, and Jeannerod (1991), for example, demonstrated quick reactions to online location perturbations. Others have shown that individuals can also compensate well for online size perturbations (Castiello, Bennett, & Chambers, 1998; Castiello, Bennett, & Stelmach, 1993; Glover, Miall, & Rushworth, 2005; Paulignan, Jeannerod, Mackenzie, & Marteniuk, 1991; van de Kamp, Bongers, & Zaal, 2009) until quite late in the course of a movement (Hesse & Franz, 2009). Likewise, an initially inappropriate hand orientation can be corrected to match target orientation in late phases of a grasping movement (Gosselin-Kessiby, Messier, & Kalaska, 2008), and perturbations of target orientation are compensated for quickly (Desmurget & Prablanc, 1997; Desmurget et al, 1996, 1995).…”

“…The function of control is to quickly process motorvisual feedback signals to launch rapid online corrections for potential spatial movement–goal mismatches. Thus, processing speed is an important aspect of control (see, e.g., van de Kamp et al, 2009) that demands attentional focus but practically precludes the integration of any substantial amount of non-essential contextual information (except focused and spatial information).…”

Previous research on dual-tasks has shown that, under some circumstances, actions impair the perception of action-consistent stimuli, whereas, under other conditions, actions facilitate the perception of action-consistent stimuli. We propose a new model to reconcile these contrasting findings. The planning and control model (PCM) of motorvisual priming proposes that action planning binds categorical representations of action features so that their availability for perceptual processing is inhibited. Thus, the perception of categorically action-consistent stimuli is impaired during action planning. Movement control processes, on the other hand, integrate multi-sensory spatial information about the movement and, therefore, facilitate perceptual processing of spatially movement-consistent stimuli. We show that the PCM is consistent with a wider range of empirical data than previous models on motorvisual priming. Furthermore, the model yields previously untested empirical predictions. We also discuss how the PCM relates to motorvisual research paradigms other than dual-tasks.

“…Control constantly compares predictions based on the actual state of the movement with incoming sensory information, in order to minimize mismatch between movement goal and prospective course of the movement (Wolpert et al, 1998; Wolpert and Ghahramani, 2000; Bubic et al, 2010). Movement control works at high speed and can rapidly correct for movement disturbances and perturbations in target size, location, or orientation (Prablanc and Pélisson, 1990; Gosselin-Kessiby et al, 2008; Hesse and Franz, 2009; van de Kamp et al, 2009). …”

Ideomotor theory claims that perceptual representations of action-effects are functionally involved in the planning of actions. Strong evidence for this claim comes from a phenomenon called motorvisual priming. Motorvisual priming refers to the finding that action planning directly affects perception, and that the effects are selective for stimuli that share features with the planned action. Motorvisual priming studies have provided detailed insights into the processing of perceptual representations in action planning. One important finding is that such representations in action planning have a categorical format, whereas metric representations are not anticipated in planning. Further essential findings regard the processing mechanisms and the time course of ideomotor cognition. Perceptual representations of action-effects are first activated by action planning and then bound into a compound representation of the action plan. This compound representation is stabilized throughout the course of the action by the shielding of all involved representations from other cognitive processes. Despite a rapid growth in the number of motorvisual priming studies in the current literature, there are still many aspects of ideomotor cognition which have not yet been investigated. These aspects include the scope of ideomotor processing with regard to action types and stimulus types, as well as the exact nature of the binding and shielding mechanisms involved.
