“…The working hypothesis that we would find a steeper slope for object-based transformations compared to egocentric ones was confirmed. Of course, this fits with the existing literature (Keehner et al, 2006;Michelon & Zacks, 2006). However, the novelty of the present findings is in showing that there is no need to use different sets of stimuli or to use embodied stimuli to observe this effect.…”

“…However, the typical increase of response times with increasing angular disparity is more evident in object-based transformations than in egocentric ones (Jola & Mast, 2005;Michelon & Zacks, 2006). Specifically, in egocentric transformations the function of response time on angle of rotation tends to show a significant increase only for angles above 60°or 90° (Keehner et al, 2006;Michelon & Zacks, 2006), resulting in a shallower slope for egocentric than for object-based transformations. This finding has been interpreted as reflecting the use of visual matching for smaller angles under egocentric judgments, whereas larger angles involve greater mental efforts because of the need for perspective transformation.…”

Two experiments were conducted to address methodological issues with past studies investigating the influence of egocentric and object-based transformations on performance and sex differences in mental rotation. In previous work, the egocentric and object-based mental rotation tasks confounded the stimulus type (embodied vs. non-embodied) and transformation task (egocentric vs. objectbased). In both experiments presented here, the same stimuli were used regardless of the type of transformation but task instructions were modified to induce either egocentric (left-right judgment) or object-based (same-different judgment) processing. Experiment 1 used pairs of letters whereas Experiment 2 presented pairs of line-drawings of human hands. For both experiments, it was hypothesized that the mental rotation slope for response time would be steeper for object-based than for egocentric transformations. This hypothesis was verified in both experiments. Furthermore, Experiment 2 showed a reduced male advantage for egocentric compared to object-based rotations, whereas this pattern was reversed for Experiment 1. In conclusion, the present study showed that the influence of the type of transformation involved in mental rotation can be examined with the same set of stimuli simply by modifying task instructions.

“…Whereas previous studies have highlighted the role of integrating motor signals and proprioceptive information (Amorim et al, 2006;Creem-Regehr, Neil, & Yeh, 2007;Keehner, Guerin, Miller, Turk, & Hegarty, 2006;Kessler & Thomson, 2010;Parsons, 1987;Vogeley et al, 2004;Wraga, 2003;Zacks & Michelon, 2005), this study underlines the central importance of vestibular information for embodied perspective taking. These signals may be of particular importance for mental imagery with respect to one's entire body as opposed to imagery for body parts (Parsons, 1987) where motor and proprioceptive mechanisms may predominate.…”

Imagined own-body transformations during passive self-motion

Spatial perspective taking is a crucial social skill that underlies many of our everyday interactions. Previous studies have suggested that spatial perspective taking is an embodied process that involves the integration of both motor and proprioceptive information. Given the importance of vestibular signals for own-body perception, mental own-body imagery, and bodily self-consciousness, in the present study we hypothesized that vestibular stimulation due to passive own-body displacements should also modulate spatial perspective taking. Participants performed an own-body transformation task while being passively rotated in a clockwise or counter-clockwise direction on a human motion platform. A congruency effect was observed, reflected in faster reaction times if the implied mental body rotation direction matched the actual rotation direction of the chair. These findings indicate that vestibular stimulation modulates and facilitates mental perspective taking, thereby highlighting the importance of integrating multisensory bodily information for spatial perspective taking.

“…Moreover, the selective activation of the right postcentral gyrus in the MIR task supports previous work on perspective-taking, showing that first-person conceptual perspective and 1PP in emotional contexts more activates the postcentral gyrus compared with 3PP Decety, 2003, 2004). Accordingly, we hypothesize that these different behavioral-neural patterns in embodied and disembodied self-location may relate to first-person (MIR task) and thirdperson (SPO/OBT task) perspective-taking, respectively, linking the neural mechanisms of perspective-taking to those of mental body transformations (Keehner et al, 2006).…”

Substantial data from the cognitive neurosciences point to the importance of bodily processing for the development of a comprehensive theory of the self. A key aspect of the bodily self is self-location, the experience that the self is localized at a specific position in space within one's bodily borders (embodied self-location). Although the neural mechanisms of self-location have been studied by manipulating the spatial location of one's visual perspective during mental imagery, such experiments were conducted in constrained, explicit, and unecological contexts such as explicit instructions in a prone/seated position, although most human interactions occur spontaneously while standing/walking. Using a motor paradigm, we investigated the behavioral and neural mechanisms of spontaneous self-location and mental body transformations during active human interaction. Using own-body imagery using spontaneous and explicit changes in self-location in standing participants, we report that spontaneous interactions with an avatar are neurally indistinguishable from explicit own-body transformation with disembodied self-location but differ from explicit own-body transformation with embodied self-location at 400 -600 ms after stimulus onset. We discuss these findings with respect to the neural mechanisms of perspective-taking and selflocation in spontaneous human interaction.
