Autobiographical Memory in Schizophrenia Spectrum Disorders

Autobiographical memory encompasses the personal recollection of past experiences that shape our identity and inform our understanding of self. In schizophrenia spectrum disorders, this faculty is frequently disrupted, manifesting as reduced specificity, impaired temporal ordering and diminished thematic coherence. Patients often report overgeneral recall, recalling categories of events rather than discrete episodes, and struggle to integrate personal experiences into a unified life narrative. Underlying these difficulties are deficits in executive functions and hippocampal processing, as well as alterations in self‐reflection and narrative reasoning. Such impairments have profound consequences for social functioning, clinical insight and emotional regulation, hampering patients’ ability to learn from past experiences and anticipate future scenarios. Recent work has focused on delineating the cognitive and neural mechanisms of autobiographical memory dysfunction, its impact on attributional biases and on developing targeted interventions to strengthen encoding, retrieval and narrative integration. Understanding these memory alterations is crucial for designing cognitive remediation programmes that can restore personal continuity and improve everyday outcomes for individuals with schizophrenia spectrum disorders.

Research from Nature Portfolio

Studies of life narratives in schizophrenia reveal preserved cultural biographical knowledge but marked deficits in temporal coherence, causal‐motivational linkage and thematic integration. These coherence impairments correlate with executive dysfunction, suggesting that strengthening executive control may enhance narrative construction. Investigations into temporal processing show that while direct dating of significant events remains intact, patients rely less on contextual cues and combine fewer inferential strategies when placing past and future events in time, leading to increased ordering errors. Research on the interplay between memory and social cognition demonstrates that retrieval of negative autobiographical memories is associated with a heightened tendency to attribute hostility in ambiguous social situations. This link suggests that bias towards negative personal recollections may underpin misinterpretation of others’ intentions, with implications for therapeutic approaches targeting memory valence and social attribution.

Autobiographical Memory in Schizophrenia Spectrum Disorders publication trend

The graph below shows the total number of articles in autobiographical memory in schizophrenia spectrum disorders across all publications each year (not limited to Nature Index journals).

Technical terms

Autobiographical memory: Personal remembrance of events and experiences that define one’s life story.

Specificity: The extent to which a memory includes unique temporal, spatial and contextual details of a single event.

Thematic coherence: The organisation of individual memories around central themes that reflect personal identity.

Mental time travel: The capacity to mentally project oneself into past experiences or future scenarios.

Executive function: High‐level cognitive processes, such as planning and cognitive flexibility, that support goal‐directed behaviour.

Overgeneral memory: Tendency to recall general categories of events rather than distinct episodes, often linked to cognitive and affective dysfunction.
