<p>The aim of the study was to investigate how emotion
information processing factors, such as alexithymia and emotional intelligence,
modulate body ownership and influence multisensory integration during the
‘rubber hand illusion’ (RHI) task. It was previously shown that alexithymia
correlates with RHI, and we suggested that emotional intelligence should also
be a top-down factor of body ownership, since it was not shown in previous
experiments. We elaborated the study of Grynberg and Pollatos [<i>Front. Hum.
Neurosci</i>. <b>9 </b>(2015) 357] with an additional measure of emotional
intelligence, and propose an explanation for the interrelation of emotion and
body ownership processing. Eighty subjects took part in the RHI experiment and
completed the Toronto Alexithymia Scale and the Mayer–Salovey–Caruso Emotional
Intelligence Test (MSCEIT). Only MSCEIT was detected to be a significant
predictor of the subjective measure of the RHI. There were no significant
correlations between alexithymia scores and the test statements of the RHI or
the proprioceptive drift, thus we did not replicate the results of Grynberg and
Pollatos. However, alexithymia correlated with the control statements of
subjective reports of the illusion, which might be explained as a disruption of
the ability to discriminate and describe bodily experience. Therefore, (1)
alexithymia seems to be connected with difficulties in conscious or verbal
processing of body-related information, and (2) higher emotional intelligence
might improve multisensory integration of body-related signals and reflect
better predictive models of self-processing.</p>
