    Fading Affect Bias (FAB) refers to the relative preservation of positive emotions over negative emotions in autobiographical memory. In retrospective methods, the selection of recall may be influenced by the detail of memories. Therefore, a longitudinal method from encoding to recall is required. The current study examined to develop a diary method to investigate the effects of alternation in memory details on the FAB. Participants recorded the emotions and subjective characteristics of memory for 10 days and then recalled and evaluated them after 1 month and 6 months. The results showed that the FAB did not occur, but that there was a negative correlation between the subjective characteristics of memory and fading affect intensity of both emotional valences, and a positive correlation between the subjective characteristics at encoding and recall. The results suggest that the decrease in the subjective characteristics of memory causes fading emotional intensity regardless of emotional valence.
