Intersubjectivity and psychopathology: Borderline and psychosomatic bodies “at the mind’s limits”

The Relationship Between Childhood Traumatic Experiences and Bodily Distress Syndrome: The Mediating Role of Somatoform Dissociation

This research aimed to investigate the relationship between childhood traumatic experiences and bodily distress syndrome, and the mediating role of somatoform dissociation. A total of 241 individuals living in Iran aged 20-40 years (M = 26.41 years, SD = 6.30; 74.7% females) were selected by convenience sampling to participate online in the research in March 2023. They answered the Childhood Trauma Questionnaire (CTQ-SF), the Bodily Distress Syndrome Checklist (BDS-25), and the Somatoform Dissociation Questionnaire (SDQ-20). The results of the structural equation modeling showed that the model had a good fit, and significant relationships were observed between childhood traumatic experiences and bodily distress syndrome, between childhood traumatic experiences and somatoform dissociation, and also between somatoform dissociation and bodily distress syndrome. The results indicated that somatoform dissociation partially mediates the relationship between childhood traumatic experiences and bodily distress syndrome. Furthermore, the prevalence of bodily distress syndrome was higher in the female than the male participants. The results thus highlight the role of childhood traumatic experiences and somatoform dissociation in creating bodily distress syndrome.

An integrative perspective on the role of touch in the development of intersubjectivity

Touch concerns a fundamental component of sociality. In this review, we examine the hypothesis that somatomotor development constitutes a crucial psychophysiological element in the ontogeny of intersubjectivity. An interdisciplinary perspective is provided on how the communication channel of touch contributes to the sense of self and extends to the social self. During gestation, the transformation of random movements into organized sequences of actions with sensory consequences parallels the development of the brain's functional architecture. Brain subsystems shaped by the coordinated activity of somatomotor circuits to support these first body-environment interactions are the first brain functional arrangements to develop. We propose that tactile self-referring behaviour during gestation constitutes a prototypic mode of interpersonal exchange that supports the subsequent development of intersubjective exchange. The reviewed research suggests that touch constitutes a pivotal bodily experience that in early stages builds and later filters self-other interactions. This view is corroborated by the fact that aberrant social-affective touch experiences appear fundamentally associated with attachment anomalies, interpersonal trauma, and personality disorders. Given the centrality of touch for the development of intersubjectivity and for psychopathological conditions in the social domain, dedicated research is urged to elucidate the role of touch in the evolution of subjective self-other coding.

The self and its internal thought: In search for a psychological baseline

Self-consciousness is neuronally associated with the brain's default mode network as its "neuronal baseline" while, psychologically the self is characterized by different thought modes and dynamics. We here raise the question whether they reflect the "psychological baseline" of the self. We investigate the psychological relationship of the self with thought modes (rumination, reflection) and mind-wandering dynamics (spontaneous, deliberate), as well as with depressive symptomatology. Our findings show a relationship between self-consciousness and i) mind-wandering dynamics, and ii) thought functional modes, in their respective forms. At the same time, self-consciousness is more related to spontaneous mind-wandering than deliberate and to rumination than reflection. Furthermore, iii) rumination acts as a mediator between self-consciousness and spontaneous mind-wandering dynamics; and iv) the relationship between high levels of self-consciousness and depressive symptoms is mediated by ruminative modes and spontaneous mind-wandering dynamics. Together, these findings support the view of the self as "psychological baseline".
