Spatial Perspective Taking during Passive Whole-Body Rotation: A Replication of van Elk and Blanke (2014)

Resumen

Spatial perspective taking, an essential skill for social interaction, enables the adoption of another individual’s viewpoint. Van Elk and Blanke (2014) demonstrated that vestibular stimulation modulates spatial perspective taking. This study aims to replicate and expand this finding. Therefore, twenty participants performed a mental body transformation task while seated on a chair that rotated alternately in a clockwise and counterclockwise direction. Each participant completed trials during both the acceleration and deceleration phases of the chair rotation. During the acceleration phase, an interaction was observed between chair rotation direction and implied mental body rotation direction, indicating a congruency effect: Reaction times were faster when the implied mental body rotation direction matched the chair rotation direction during the acceleration phase. This was not found in the deceleration phase. These findings are consistent with those of the original study. Furthermore, a three-way interaction between chair rotation direction, implied mental body rotation direction, and rotational phase was discovered, which was not examined in the original study. This suggests that the previously noted interaction varies between the acceleration and deceleration phases. These findings support that vestibular stimulation modulates spatial perspective taking but also highlight the impact of the rotational phase on this process.
