--- - |2+ Abstract Objective Dissociation refers to a disintegration between psychological elements; common manifestations are embodied in “absorption and imaginative involvement,” a propensity for being immersed in a stimulus while oblivious to the environment, and acting without awareness. Trait dissociation was hypothesized to relate to lower EEG signal connectivity, but studies on healthy populations are scarce. The present study set out to examine whether dissociative absorption in a nonclinical sample would be associated with decreased intrahemispheric coherence. Method In 84 healthy Israeli soldiers (49% females; Mage = 22.24, SD = 2.64), resting‐state electroencephalography (rsEEG) was recorded for a period of 3 min with eyes closed and 3 min with eyes open. Results Decreased coherence was related to high dissociative absorption in the long (frontal‐occipital) range, and in one of the pairs of the short range (central‐parietal). The effects emerged mostly in the left hemisphere, in both eyes‐open and eyes‐closed conditions, and for a range of spectral bands, although long‐range effects were more pronounced in slow‐wave bands (theta and delta). Conclusions Dissociative absorption is manifested in segregated cortical activity, supporting the notion that it may represent less integrated mental functioning. The findings contribute to our understanding of the neural correlates of consciousness and personality. - Journal of Personality, EarlyView.
