Highly Superior Autobiographical Memory (HSAM)

From Kook Science

Highly Superior Autobiographical Memory (HSAM), also referred to by the neologism hyperthymesia, is a form of conditional memory characterised by deep consolidation of personal experiences coupled with vivid recall provoked by uncontrolled association, whereby an individual with such memory will experience extraordinary recall of personal life events on an involuntarily basis to the detriment of ability to focus on non-personal information or abstract possibilities.
