“…These findings were reproduced in other labs (e.g. Newport et al, 2002;Kaas and van Mier, 2006;Fernández-Díaz and Travieso, 2011). This reference frame coincides with a physical reference frame fixed to the table.…”

“…These discrepancies may be explained by the fact that these other studies employed different perceptual and motor tasks. For example, in geometric matching tasks, the movement and the position of the arms seemed to play a role in the misperception of orientations 26 . In the 180° condition shown in Fig.…”

“…Cutaneous inputs, proprioceptive inputs, and movement information were all found to contribute to shape perception or the perception of angular relationships 20 . Movement 21 , 22 , motor 23 , or proprioceptive 24 , 25 information were also found to contribute to length and distance perception, and so did arm-hand configurations 11 , 26 and head positions 27 . Depending on the task, each of these inputs could be relevant or available, and could potentially explain the diversity of reference frames previously observed.…”

The shape of objects is typically identified through active touch. The accrual of spatial information by the hand over time requires the continuous integration of tactile and movement information. Sensory inputs arising from one single sensory source gives rise to an infinite number of possible touched locations in space. This observation raises the question of the determination of a common reference frame that might be employed by humans to resolve spatial ambiguity. Here, we employ a paradigm where observers reconstruct the spatial attributes of a triangle from tactile inputs applied to a stationary hand correlated with the voluntary movements of the other hand. We varied the orientation of the hands with respect to one another and to the trunk, and tested three distinct hypotheses regarding a reference frame used for integration: a hand-centred, a trunk-centred or an allocentric reference frame. The results indicated strongly that the integration of movement information and tactile inputs was performed in a radial trunk-centred reference frame.

“…This illusory rotation was predicted from results of a parallelity experiment: if participants have to make a test bar located to their right parallel to a reference bar located to their left, the test bar is always rotated clockwise with respect to the reference bar, e.g. [2][3][4][5][6] (see also Figure 1). Kappers showed that this rotation gradually and systematically increased with distance [7].…”

Abstract. Recently, we have shown that a translating bar on which blindfolded participants position their hand is perceived as also rotating. Here, we investigated whether such an illusory rotation would also be found if a sphere or a plane (i.e. a stimulus without a clear orientation) was used as translating stimulus. We indeed found similar rotation biases: on average a stimulus that translates over a distance of 60 cm has to rotate 25 • to be perceived as non-rotating. An additional research question was whether the biases were caused by the same underlying biasing egocentric reference frame. To our surprise, the correlations between the sizes of the biases of the individual participants in the various conditions were not high and mostly not even significant. This was possibly due to day-to-day variations, but clearly, more research is needed to answer this second research question.
