Autobiographical memory
Summary
Autobiographical memory (AM) is a memory system consisting of episodes recollected from an individual's life, based on a combination of episodic (personal experiences and specific objects, people and events experienced at particular time and place) and semantic (general knowledge and facts about the world) memory. It is thus a type of explicit memory.
Conway and Pleydell-Pearce (2000) proposed that autobiographical memory is constructed within a self-memory system (SMS), a conceptual model composed of an autobiographical knowledge base and the working self.
The autobiographical knowledge base contains knowledge of the self, used to provide information on what the self is, what the self was, and what the self can be. This information is categorized into three broad areas: lifetime periods, general events, and event-specific knowledge.
Lifetime periods are composed of general knowledge about a distinguishable and themed time in an individual's life. For example, the period spent at school (school theme), or entering the workforce (work theme). Lifetime periods have a distinct beginning and ending, but they are often fuzzy and overlap. Lifetime periods contain thematic knowledge about the features of that period, such as the activities, relationships, and locations involved, as well as temporal knowledge about the duration of the period. The thematic information in these periods can be used to group them together under broader themes, which can reflect personal attitudes or goals. As an example, a lifetime period with the theme of "when I lost my job" could fall under the broader category of either "when everything went downhill for me" or "minor setbacks in my life."
General events are more specific than lifetime periods and encompass single representations of repeated events or a sequence of related events. General events group into clusters with a common theme, so that when one memory of a general event is recalled, it cues the recall of other related events in memory.
