transience - This is one of the seven sins of memory that affect our ability to remember. Other six sins are absent mindedness, blocking, misattribution, suggestibility, bias and persistence. Transience refers to deterioration of certain memories as time passes. This happens because each time the memory is retrieved, it is altered before storing back within the hippocampus. This could be because of older memories or newer memories inhibiting, interfering with or modifying that particular memory.
