Time course of body recognition in women with weight and shape concerns assessed by steady-state visual evoked potentials (SSVEP)

摘要

This study aimed to examine self-body recognition in women with high (HWSC) and low weight and shape concerns (LWSC). Thus, the detection rate, the reaction time and the perceptual threshold for recognizing one's own body in a morphed body were measured in n = 25 women with HWSC and n = 26 women with LWSC. Furthermore, by using steady-state visual evoked potentials (SSVEPs), neuronal correlates of body recognition were recorded. The perceptual threshold for recognizing one's own body was higher for women with HWSC in the case of a morph with a thinner body. No group differences emerged for morphs with obese or average-weight bodies. The SSVEP amplitudes did not differentiate between one's own and another body in either group. The results suggest that for women with HWSC, their negative body schemata might hamper recognition of their own body in a thinner morph. Otherwise, self-body recognition is similar in women with LWSC and HWSC.
