Memory Sins in Applied Settings: What Kind of Progress?

Journal of Applied Research in Memory and Cognition, 2022
Over two decades ago, I proposed that memory errors could be classified into seven basic categories or sins (Schacter, 1999, 2001), comprising three sins of omission (transience, absentmindedness, and blocking) and four sins of commission (misattribution,
