ویژگی های پدیده شناختی حافظه در افراد غیر بالینی

A central hypothesis of recovered memory is that the source of the memory may be misattributed, and the memory of an imagined event may be mistaken as the memory of the perceived event that was not remembered. The judgment of memory source depends upon phenomenological characteristics. Thus, the present study investigated characteristics of recovered memory. To exclude potential confounding effects of traumatic stress and acute mental illness, data on recovered memories of diverse valences in a nonclinical sample were collected. Self-report scales including a measure of memory characteristics were used to evaluate recovered memories and age-matched autobiographical memories that had been continuously remembered. The results showed that recovered memory was of lower clarity and contained less detailed sensory, contextual, and temporal information; additionally, it was associated with fewer thoughts and lower intensity of feelings. Participants also felt less confident regarding the veracity of recovered memory in comparison with continuous memory. In contrast to recovered trauma memory reported by clinical clients, vivid sensory details and intense affect did not characterize recovered memory in nonclinical individuals. The reduction in perceptual and contextual information, as well as cognitive operations, may increase the difficulty of judging the source of recovered memory.
