Who wrote that? Automaticity and reduced sense of agency in individuals prone to dissociative absorption.

Dissociative absorption (DA) is a tendency to become completely immersed in a stimulus while neglecting to attend to one's surroundings. Theoretically, DA implies automatic functioning in areas that are outside the focus of attention. This study examined whether high absorbers indeed act more automatically, i.e., with decreased meta-consciousness for, and therefore poor memory of, their own actions, along with reduced sense of agency (SoA). High and low absorbers (N = 63) performed three DA-promoting tasks: choice-reaction time (CRT), Tetris, and free writing. Participants were tested on memory of task details and self-reported their state SoA. As hypothesized, trait DA was correlated with impaired autobiographical memory for self-generated writing. However, DA was not related to episodic memory disruptions in externally-generated content tasks (Tetris, CRT). In most tasks, DA was associated with decreased SoA. Absorbers' specific difficulty in identifying self-generated content suggests that their memory failures stem from reduced accessibility to self-actions and intentions.

Posttraumatic symptoms and poor sleep are independent pathways to agency disruptions and dissociation: A longitudinal study with objective sleep assessment.

Dissociation and diminished sense of agency are experiential distortions of disintegration in the perception of self and action. Although one is often implied in the other, they are seldom studied together. Assessing their relationship and shared influences may allow for a more comprehensive and nuanced understanding of dissociative experiences. We aimed to examine their temporal (concurrent or directional) co-occurrence, and to elucidate their etiology, focusing on posttraumatic symptoms (PTS), poor sleep, and their hypothesized joint effect. N = 113 adults oversampled for the existence of trauma exposure history reported PTS and then, for a week, wore an actigraphic sleep monitor, reported subjective sleep quality each morning, and reported state dissociation (depersonalization, derealization, and absorption) and sense of agency four times each day. Data were analyzed using multilevel linear modeling. Higher state dissociation correlated with diminished state sense of agency, but only contemporaneously, not directionally. Both hypothesized etiological factors, namely, PTS (especially complex) and poor sleep (objective and subjective) predicted state dissociation and diminished state sense of agency, but psychological distress seemed to overshadow these main effects. However, robust interactive effects suggested that poor sleep predicted dissociation and disruptions in the sense of agency only among individuals with low PTS. These findings suggest that PTS and poor sleep quality are separate paths to dissociation and impaired sense of agency. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

The Interplay Between Childhood Sexual Abuse, Self-Concept Clarity, and Dissociation: A Resilience-Based Perspective.

BACKGROUND: Despite a robust consensus regarding the potentially negative implications of childhood sexual abuse (CSA), research investigating risk and protective factors-particularly among well-functioning young adults-is scant. Dissociation is one of the major maladaptive outcomes of CSA. Nevertheless, CSA explains only about 10% of the variance of dissociation. Possibly, this modest effect size is due to protective factors moderating the relation between CSA and dissociative symptoms. One such factor may be the extent to which one has succeeded in developing a clear and coherent sense of who they are. OBJECTIVE: We aimed to explore whether self-concept clarity (SCC) moderates the relationship between CSA and dissociation (Model 1), and an alternative hypothesis, whereby CSA may moderate the relationship between SCC and dissociation (Model 2). PARTICIPANTS AND SETTING: This was tested among 65 well-functioning young women drawn from an earlier study that intentionally oversampled CSA survivors. METHODS: We included data from survivors of CSA by a known perpetrator (n = 35) and women with no sexual trauma (n = 30). RESULTS: Findings were consistent with both Model 1 and Model 2, but only when depersonalization-derealization, namely detachment, was considered. Simple effects analyses revealed that CSA was related to depersonalization-derealization only under low SCC levels (Model 1), and SCC was negatively related to depersonalization-derealization only in the CSA group (Model 2). CONCLUSIONS: Findings suggest that SCC is a protective factor, buffering the association between CSA and detachment (depersonalization-derealization) symptoms. Clinical implications are discussed.
