1 Conway’s ModelThe Self Memory System (SMS) has two principle components:-1. Autobiographical knowledge baseorganised specifically to support our sense of self2. The (working) Selfcomprises a goal hierarchy, and various other internal mechanisms(Download the Conway (2005) PDF from my webpage )
2 ‘Self’ Autobiographical Knowledge Base Self-related semantic knowledge Abstracted from specificexperiencesEpisodic Memory tied to specific experiences(e.g. the CMF).EncodingConsolidationRetrieval
3 Take a peek inside yourself… Goal HierarchyEpisodic Memory(CMF)Autobiographical Knowledge BaseConceptual Self.semantic knowledgeKey point: the SMS system is ‘goal-driven’
4 The SMS greatly extends the CMF Conway: “all daily experiences are destined to be forgotten”Unless they support longer-term goalsIn the short term, accurate memories are vitalWhere did I leave my keysIn the long-term, coherence (between goals) is vitalThe ‘Husband-Hermit’ or ‘Saint-Sinner’ dilemma
5 SMS Goals But: there is an accuracy-coherence trade-off! Short term (e.g. daily)Take the car for a service…Find the keys…Post the letter…Overriding principle: accuracy!Long-termGet a jobLearn how to driveBuy a houseBecome a solitary religious hermitBe a loving husbandOverriding principle: coherencePotential for conflict!But: there is an accuracy-coherence trade-off!
6 How is the trade-off achieved? Goal HierarchyEat and drink (everyday)Keep warm (everyday)Have a conversation (most days)Watch TV (particular times)Find the car keys (in 5 minutes)Avoid tripping up (when I walk)Post the letter (sometime today)Dentist appointment (this week)Revise (next month)Obtain graduation ball tickets (next few months)Find a less annoying partner (yesterday!)Get a 2:1 (next couple of years)Loose weight (before going on holiday)The goal hierarchy acts to maintain a stable and coherent set of short and long term goalsThe goal hierachy is dynamic – at different times, different goals become activated. To the extent that this could produce conflicting demands on behaviour, the goal hierarchy needs to maintain a certain coherence among the goals.
7 The SMS: key pointsNew memories are not formed ‘automatically’ from our experiencesBut, experiences are always encoded (e.g. as per the CMF).An ABM is formed (and retrieved) only when the (working) self interacts with the autobiographical knowledge baseSuch interactions are entirely goal-drivenHence, specific experiences will be forgotten unless they relevant to a goal - within the goal hierarchyStable self-image emerges from the coherence imposed by the goal hierarchy, perhaps at the expense of accuracy
