[en] Phenomenal characteristics of autobiographical memories and imagined experiences were examined in checking- and non-checking-prone individuals. Participants were asked to retrieve a positive, a negative and a neutral memory, and to imagine a positive, a negative and a neutral experience. They were then requested to evaluate each event according to characteristics such as sensory and contextual details. The main results revealed that non-checking-prone participants reported more general vividness than checking-prone individuals for real events. In addition, non-checking-prone individuals reported more visual details and vividness for real than imagined experiences, while no difference between real and imagined events was found for checking-prone participants. These results suggest that checking-prone participants report poor memories of real events, which could in turn explain their difficulties distinguishing between real and imagined events.
