Working Memory
System for temporarily maintaining mental representations that are relevant to the performance of a cognitive task in an activated state, or memory you use when engaged in a cognitive task
7 sins of memory
Transcience Absent mindedness Blocking Bias Suggest ability Persistence Misattribution
Working Memory Diagram
WM- Executive Attention vs ST Store (Visual/spatial/verbal)
Baddely
1986
Central Executive
Visual spatial Sketchpad/Episodic Buffer/Phonological Loop
LTM
Baddeley Central Executive
- Supervisory Control of System
- Coordinates 2 storage compartments
- Focuses and Switches attention
- Retrieves Representations from LTM
Baddeley Visual Spatial
- Transient storage of visual/spatial representations
* Maintains active memory via rehearsal of image generation or action preparation
Baddeley Episodic Buffer
*Transient Storage of integrated events
Baddeley Phonological Loop
- Transient storage of verbal representations
* Maintains active memory via rehearsal, mechanism of inner speech
Baddeley Long Term Memory
- Permanent Storage of Integrated Events
* Permanent Storage of visual & verbal semantic knowledge
Types of Long Term Memory
Explicit/Declarative- episodic/semantic, what
Implicit/Nondeclarative- procedural/skills/conditioned responses, how
SAM
Parker, Cahill, McGaugh (2006), amplified white matter tract coherence, enlarged temporal lobe & caudate nucleus (habits, skill learning, ocd)
Chattering Mind
- repetitive and automatic
- positive/negative tone of self statements
- impact of mind chatter on attention and concentration
- universality of experience
Encoding Specificity
overlap between operations at encoding and operations at retrieval TOT Context-Dependent Mood Congruence State-Dependent
Context Dependent Learning
Godden & Baddeley (1975) Scuba word recall- dry/dry, wet/wet, dry/wet, wet/dry
State Dependent Learning
Person’s state of consciousness during learning and retrieval, better with matching states, Caffeine Study- Keleman & Creeley (2003)
Mindfulness Study
Zeidan, 2010, 63 students, 4 sessions, measured emotional regulation and cognitive ability
Process of LTM
Attention-Encoding-Storage-Retrieval
3 store model of LTM
Stimuli - Sensory Memory - (Attention) - STM (Maintenance Rehearsal) (Information Retrieval) - (Retrieval) (Elaborative Rehearsal) - LTM
Prospective memory
remembering to take some action at a specific time in the future- effortful retrieval (continuous monitoring for clues) or spontaneous retrieval
Constructive Character of Memory
schemas influence our perceptions by providing expectations, schemas play a role in constructing episodic memories at encoding and in reconstructing them at retrieval
Reconstructive Retrieval
schema guided construction of episodic memories that alter and distort encoded memory representations, how we retrieve memories shows that memory is constructive in nature
*Brewer & Treyens (1981)- psychologists office, ¼ recalled unusual items (skull), some participants recalled books (false)
Associations and Memory Error
we remember the gist of information (meaning), likely to make mistakes on details- memories dominated by understanding of meaning, not raw materials of experience
Photos and False Autobiographical Events
Lindsay et al (2004), asked undergrads to recall 2 true memories and one false one, half of participants shown actual class photo from relevant time period, Less than 50% reconstructed full false memory of slime event, in class photo condition, 70% remembered slime event
Memory Accuracy
accuracy is not predicted by
- confidence
- details
- strong emotion
