“…Comparable effects are observed when the position of the hand is represented by a visual marker (such as a dot) moving in the same plane as the hand: after visuomotor adaptation to misaligned visual feedback, the felt position of the hand drifts towards the seen marker position (e.g., Izawa, Criscimagna-Hemminger, & Shadmehr, 2012;Salomonczyk, Henriques, & Cressman 2012). Similar effects were reported recently even without extensive visuomotor adaptation when hand movements were translated into cursor movements in a different plane (Rand, Wang, Müsseler, & Heuer, 2013). Thus, the proprioceptive perception of the hand seems to be attracted by its visual position even if that position is indicated by an extrinsic object.…”

The temporal interval between an action and its ensuing effect is perceptually compressed. Specifically, the perceived onset of actions is shifted towards their effects in time and, vice versa, the perceived onset of effects is shifted towards their causing actions. In four experiments, we report evidence showing that action-effect binding also occurs in the spatial domain. Participants controlled the location of a visual stimulus by performing stylus movements before they judged either the position of the stylus or the position of the visual stimulus. The results yielded spatial binding between the perceived stylus position and the perceived stimulus position when the stimulus was under full control of the hand movement compared to control conditions without direct control.

“…Accordingly, it should be possible to identify a second, implicit rather than explicit, representation of the direction of the hand. For this purpose, we devised a task that enables an indirect (or implicit) measure of the sensed hand direction [18]. This measure exploits error propagation in successive aiming movements [19]–[21], in particular the propagation of errors that originate from visually induced discrepancies between the physical and the perceived position of the hand [22]–[24].…”

Understanding the interactions of visual and proprioceptive information in tool use is important as it is the basis for learning of the tool's kinematic transformation and thus skilled performance. This study investigated how the CNS combines seen cursor positions and felt hand positions under a visuo-motor rotation paradigm. Young and older adult participants performed aiming movements on a digitizer while looking at rotated visual feedback on a monitor. After each movement, they judged either the proprioceptively sensed hand direction or the visually sensed cursor direction. We identified asymmetric mutual biases with a strong visual dominance. Furthermore, we found a number of differences between explicit and implicit judgments of hand directions. The explicit judgments had considerably larger variability than the implicit judgments. The bias toward the cursor direction for the explicit judgments was about twice as strong as for the implicit judgments. The individual biases of explicit and implicit judgments were uncorrelated. Biases of these judgments exhibited opposite sequential effects. Moreover, age-related changes were also different between these judgments. The judgment variability was decreased and the bias toward the cursor direction was increased with increasing age only for the explicit judgments. These results indicate distinct explicit and implicit neural representations of hand direction, similar to the notion of distinct visual systems.

“…2) or their slow introduction analogous to “prismatic shaping” (Dewar, 1971) which does not give rise to explicit knowledge (e.g., Buch et al, 2003; Cressman et al, 2010). The age-related changes in the explicit component have been hypothesized to be related to structural changes in particular of the frontal lobes (e.g., Heuer and Hegele, 2008) and to functional changes such as increased neural noise and neural de-differentiation (e.g., Rand et al, 2013). Such changes should result in a reduced sensitivity for the difference between the directions of hand movements and cursor motions, which has been reported by Rand et al (2013).…”

Visuo-motor adaptation suffers at older working age. The age-related decline of behavioral adjustments is accompanied by reduced explicit knowledge of the visuo-motor transformation. It disappears when explicit knowledge is kept constant across the age range, except for particularly high levels of explicit knowledge. According to these findings, at older adult age both the acquisition of explicit knowledge and its application for strategic corrections become poorer. Recently it has been posited that visuo-motor adaptation can involve model-free reinforcement mechanisms of learning in addition to model-based mechanisms. We tested whether age-related declines of reinforcement learning can also contribute to the age-related changes of visuo-motor adaptation. Therefore we enhanced the contribution of reinforcement learning to visuo-motor adaptation by way of introducing salient markers of success and failure during practice. With such modified practice conditions, there were residual age-related variations of behavioral adjustments at all levels of explicit knowledge, even when explicit knowledge was absent. The residual age-related variations were observed for practiced target directions only, but not for new target directions. These findings are consistent with an age-related decline of model-free reinforcement learning as a third factor in the age-related decline of visuo-motor adaptation. Under practice conditions, which spur model-free reward-based learning, this factor adds to the decrements of the acquisition of explicit knowledge and its use for strategic corrections.
