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 7: Accuracy rate (mean and SE) dependent on angular disparity for object-based and egocentric transformations. *p < 0.001.

Mentions: The repeated-measures analysis of variance score showed one main effect of the factor “angular disparity” on accuracy rates, F(1,79) = 8.94, p < 0.001, = 0.10, as illustrated in Figure 7. Bonferroni corrected t-tests revealed a significant decline in accuracy between angular disparities of 90° and 135°, t(80) = 3.38, p = 0.001. None of the other differences between consecutive angular disparities reach significance, though. Thus, the accuracy data provided only some support for the small-angle-advantage predicted in Hypothesis 6. All other effects failed to reach significance at the 0.05 level. Hence, the accuracy data provided no support for Hypotheses 1, 2, 3, 4, 5, 7, or 8.
