Disturbances of perception of subjective time have been described in schizophrenia but have not been experimentally studied until now. We investigated how patients with schizophrenia estimate the subjective temporal distance of past personal events, i.e. how these events are perceived as subjectively close or distant in time. Twenty-five patients with schizophrenia and 25 control participants recalled 24 autobiographical memories from four different life periods. They estimated the subjective TD and rated the amount of detail of each memory. Results showed that (...) patients with schizophrenia had a distorted perception of subjective TD. Their memories were significantly less detailed than those of controls and, unlike control participants, the amount of memory detail was not significantly correlated with subjective TD. Poor access to memory detail may account for distortions of perception of subjective time in patients with schizophrenia. (shrink)

Schizophrenia is a severe mental illness affecting sense of identity. Autobiographical memory deficits observed in schizophrenia could contribute to this altered sense of identity. The ability to give a meaning to personally significant events is also critical for identity construction and self-coherence. Twenty-four patients with schizophrenia and 24 control participants were asked to recall five self-defining memories. We assessed meaning making in participants’ narratives and afterwards asked them explicitly to give a meaning to their memories . We found that both (...) spontaneous and cued meaning making were impaired in patients with schizophrenia. This impairment was correlated with executive dysfunctions and level of negative symptoms. Our results suggest that patients’ difficulties in drawing lessons about past experiences could contribute to explain the lack of coherence observed in their life trajectories and their impaired social adjustment abilities. Implications for psychotherapy are also discussed. (shrink)
