This study investigates the psychological processes and the degree of psychological coherence of characters in the novella Probably Lost by Sara Salar, drawing on Donald Meichenbaum’s theoretical framework within the field of psycho-narratology. Adopting a descriptive–analytical method and relying on qualitative textual analysis, the research examines inner dialogues and mental processes as the primary data for interpretation. The findings indicate that the protagonist’s internal narrative evolves from a state of emotional disruption and fragmentation toward emotional reconstruction and the attainment of psychological coherence. Throughout this process, cognitive self-talk plays a central role in emotion regulation, memory recognition, and the reconstruction of personal identity. Moreover, the study demonstrates that analyzing characters’ inner narratives and mental dialogues enables a more precise understanding of individuation processes and emotional experience. The results underscore the significance of psycho-narratological analysis in elucidating the complex psychological and emotional interactions of characters in contemporary literature and highlight cognitive self-talk as a key mechanism in the formation of identity and psychological coherence.
