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 5: Reaction time (mean and SE) dependent on view and group for egocentric transformations. *p < 0.05.

Mentions: (1) The interaction between “view” and “group” reached significance, F(1,79) = 6.16, p = 0.015, = 0.07, see Figure 5. Post hoc tests showed that the difference between the front and the back view is significant larger for non-motor experts (M = 291.4 ms, SD = 26.5) than for motor experts (M = 200.1 ms, SD = 25.5), t(80) = –2.48, p = 0.015. That is, front view was processed slower than the back view in both motor experts (Mfront = 1042.0, SD = 50.8; Mback = 841.9 ms, SD = 33.5) and non-motor experts (Mfront = 1259.8 ms, SD = 52.7; Mback = 968.4 ms, SD = 34.7), but this difference between front and back view is reduced in motor experts. Since this interaction is restricted to egocentric transformations, this result is in line with Hypothesis 3, where we predicted that the front-view-disadvantage should be diminished in motor-experts compared to non-motor experts, especially for egocentric transformations, which are assumed to be more embodied and therefore motor simulation is required to a higher extent compared to object-based transformations.
