“…The impaired sense of agency exaggerates role of the Other's gaze in imaginary identification (blue route in Figure 1.f), leading to symptoms of depersonalization. As evidence, depressed individuals with depersonalization exhibit 8 times more often active suicidal ideation and 11 times more often passive suicidal ideation that those without depersonalization (Golubović et al, 2018). Desire for death, or passive suicidal ideation, is situated at the intersection between the Symbolic and the Real orders.…”

Suicidal ideation represents one of the most complex mental phenomena and poorly understood. This paper explores the psychic mechanisms of suicide ideation through a novel approach that combines computational methods with Lacanian psychoanalysis, specifically utilizing free energy principle (FEP). We begin by outlining foundational concepts of FEP and computational Lacanian psychoanalysis. Subsequently, we review contemporary theories of suicide thought including Interpersonal theory, Escape theory, and Lacanian and other psychoanalytic perspectives. We identify four components of suicidal ideation: symbolic suicide, imaginary suicide, desire for death, and passage of the act. A recurrent generative model is proposed that simulates suicidal impulses based on internal states and external events. We discuss enhancing the practical applicability and validating this theoretical model using real-world data like Social Readjustment Rating Scale and Personality Inventory for DSM-5 (PID-5). The predictive capability of our model is evaluating using an open-source dataset of PID-5 and Columbia Suicide Severity Rating Scale, achieving an AUC of 0.76, despite the absence of life event data. The model demonstrates the potential of generative psychometrics as a paradigm for integrating psychometric measurement with generative modeling of psychological phenomena. Further work should validate the model by incorporating external factors to refine its explanatory and predictive power. With continued development, this generative psychometric approach could provide new tools for better assessing, understanding, and treating suicidal ideation.

“…More broadly, future studies should also further assess memory recall abilities with regards to different kinds of memory content, as well as different memory systems, (e.g., episodic vs. semantic memory, seeFraiguero et al, 2021), or by contrasting DP with other mental health conditions known to impact memory processing such as anxiety and depression. For example, previous studies reported depersonalization symptomatology in severe cases of depression(Tošić Golubović, Žikić, Slavković, Nikolić, & Simonović, 2018). Given this relevant co-occurrence of altered self-narration and altered bodily feelings in dilated time experience, future research is needed to clarify what developmental trajectories the two aspects follow in diverse conditions presenting a common 'flattening' of time experience.Finally and importantly, while previous work focused on interoceptive processing in a static context, it would be important to assess it in relation to bodily movements and bodily actions, as humans need to move in order to survive.…”

Self-portrait of a Stranger: Self-face Representation and Interoception in Depersonalization Experiences

Depersonalization is a condition that makes people feel detached from one’s self, body and others. The representation of one’s own face is a salient bodily aspect of self-awareness and one’s own identity, and empirical evidence suggests that individuals with depersonalization disorder experience disrupted perception of their faces when viewing themselves in photographs or in the mirror, which has been corroborated by first-person reports. However, no study had yet explored the state of long-term self-face representations stored in visual memory in the context of depersonalization. By visualising how individuals saw themselves “in the mind’s eye”, this study provides the first empirical evidence for a relationship between depersonalization symptoms and impairments in self-face representation. Individuals reporting more frequent and intense depersonalization symptoms had lower self-face representation accuracy, but somewhat counterintuitively, also higher precision and informational content of this representation. These results suggested that individuals with high depersonalization were representing a distinct, but inaccurate, facial identity as themselves. The self-face representations of high-depersonalization participants were rated as visibly more emotionless and younger in appearance than those of low-depersonalisation participants, according to independent raters. Furthermore, specific aspects of depersonalization symptomatology, related to anomalous memory experiences, were identified as most highly related to these self-face representation characteristics. Finally, an intriguing role of interoceptive sensibility was revealed in both self-face representational accuracy and in depersonalization symptoms.
