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 (TD) 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.
目前为止，尽管在精神分裂症患者中已经描述了对主观时间的感知障碍，但尚未对其进行实验研究。我们研究了精神分裂症患者如何估计过去个人事件的主观时间距离（TD），即这些事件在时间上如何被感知为主观上的接近或遥远。25 名精神分裂症患者和 25 名对照组参与者从四个不同的生活时期回忆了 24 个自传体记忆。他们估计了主观 TD，并对每个记忆的详细程度进行了评分。结果表明，精神分裂症患者对主观 TD 的感知存在扭曲。他们的记忆明显不如对照组详细，与对照组参与者不同的是，记忆细节的数量与主观 TD 没有显著相关性。对记忆细节的获取不足可能是精神分裂症患者主观时间感知扭曲的原因。
