This chapter focuses on autobiographical memory, which relates to events and experiences in our personal past. Autobiographical memories are our recollections of specific episodes from the past. Research within different traditions and paradigms supports the view that certain kinds of memories are forgotten in apparently goal-directed ways. For instance, diary studies have suggested that whereas people are more likely to forget events about themselves that are negative rather than positive, they are more likely to forget events about others that are positive rather than negative. The retrieval-induced forgetting (RIF) paradigm developed by Anderson, Bjork, and Bjork models the kind of forgetting that occurs unconsciously in response to competition between memories, by practising some memories at the expense of others. RIF is considered an automatic, inevitable consequence of practising one piece of information at the expense of another.
