Forgetting is the loss of information that has been put into storage. To understand memory fully it is important to understand some of the factors that lead to the loss of memory. ‘Inaccuracies in memory’ addresses the question of forgetting, and considers issues with memory difficulty such as distortions, biases, ‘flashbulb’ memory situations, and the relationship between emotions and memory. Do we ever truly forget anything? Is ‘forgetting’ just an inability to retrieve memory? How does previous knowledge affect memory? What are false memories? Dan Schacter has proposed seven ‘sins’ (malfunctions) of memory: absent-mindedness, transience, blocking, misattribution, suggestibility, bias, and persistence.
