How does information get into Longterm memory LTM
- Slides: 10
How does information get into Long-term memory (LTM)? • Long-term memory (LTM) – Explicit vs. implicit memory • Encoding: “getting it into LTM” – elaborative rehearsal – depth of processing – objective and subjective organization • (Retrieval: “getting it out of LTM”)
Three-Stores Model of Memory Maintenance Attention Rehearsal Encoding Sensory Input Sensory Memory. 5” - 3” duration Working Memory LTM 10” - 15” Indefinite duration Retrieval
Types of Memory Explicit (Declarative) conscious Generic Episodic Implicit (Nondeclarative) unconscious Procedural Dispositional
Maintenance rehearsal Elaborative rehearsal Shallow processing Deep processing
(Sample from “Depth of Processing” study discussed) Word flashed: 1. judge Question: Yes No Is the word in capital letters? __ __ 2. DREAM Does the word rhyme with “cream”? __ __ 3. bread etc. Would the word fit in this sentence: “The boy used the _____ to make a sandwich. ”? __ __

Mandler’s study on the role of Subjective Organization % of items correct on later test “Intentional” learners (. . . told they would be tested later) Instructions to sort material No instructions to sort material 62% 61% “Incidental” learners (…not told they would be tested later) 60% 44%
