ABSTRACT
This experiment investigated the influence of motor expertise on object-based versus egocentric transformations in a chronometric mental rotation task using images of either the own or another person's body as stimulus material. According to the embodied cognition viewpoint, we hypothesized motor-experts to outperform non-motor experts specifically in the egocentric condition because of higher kinesthetic representation and motor simulations compared to object-based transformations. In line with this, we expected that images of the own body are solved faster than another person's body stimuli. Results showed a benefit of motor expertise and representations of another person's body, but only for the object-based transformation task. That is, this other-advantage diminishes in egocentric transformations. Since motor experts did not show any specific expertise in rotational movements, we concluded that using human bodies as stimulus material elicits embodied spatial transformations, which facilitates performance exclusively for egocentric transformations. Regarding stimulus material, the other-advantage ascribed to increased self-awareness-consciousness distracting attention-demanding resources, disappeared in the egocentric condition. This result may be due to the stronger link between the bodily self and motor representations compared to that emerging in object-based transformations.

Figure 6: Reaction time (mean and SE) dependent on view and angular disparity for egocentric transformations.

Mentions: (2) The “view” × “angular disparity” interaction was significant, F(1,79) = 30.62, p < 0.001, = 0.28, and is illustrated in Figure 6. Regarding the back view, post hoc tests showed a linear increase of RTs (p < 0.001) for angular disparities larger than 45°. The RT difference between angular disparity of 0° and 45° was not significant, t(80) = –1.06, p = 0.291. Interestingly, RT in the front view surprisingly decreased between the angular disparity of 0° and 45°, t(80) = 8.14, p < 0.001. RTs for angular disparities of 45° and 90° did not differ, t(80) = –1.29, p = 0.199. From angular disparity of 90° on there is a linear increase between successive increasing angular disparities (p < 0.001), resulting in an U-shaped pattern. This result provides some support for Hypothesis 8.
