2. The Memory System

Fig. 7.6 p. 290

2. Three Key Processes in Memory

2. (i) Sensory Memory• Stores a perfect picture of the world, but for a

fraction of a second• See Sperling’s studies p. 290

• Iconic (visual) and echoic (auditory) sensory memories

2. (i) Sperling’s Studies

From Sensory to Short-Term Memory

How does information get encoded and transferred onto the memory system?

a) Automatic processing No effort required

See implicit memories p. 312

b) Effortful processing Pay conscious effort and attention to hold info. In

short-term memory See explicit memories p. 312

2. (ii) Short-Term Memory

Semi-permanent storage Magic number: 7 (+ - 2) Information is lost after 20-30 seconds unless it is

rehearsed Maintenance rehearsal keeps the information there… Elaborative rehearsal brings the information to long

term memory Type of encoding: p.287

Type of Encoding

2. (ii) Type of encoding, p. 287

2. (ii) From Short-Term to Long-Term Memory

What helps us remember?? a) Type of encoding b) Self-referent encoding (self-schema) c) Imagery d) Mnemonics:

method of loci Acronyms: e.g. Roy G. Biv

2. (ii)…To long term memory

e) Chunking: e.g. 1-4-9-2-1-7-7-6-1-8-1-2 (1492) (1776) (1812)

f) Organize information hierarchically g) Spacing effects:

distributed practice leads to better long-term retention

h) Time: over learn! i) Mood-dependent effects

2. (iii) Long Term Memory

Where information is stored in relatively permanent form

Capacity is seemingly infinite! 2 memory systems: p. 313

Declarative: Semantic (explicit memories/encyclopedia) Episodic (implicit memories/autobiography)

Non-declarative, procedural “how to”; implicit memories based on practice or habit

2. (iii) Independent Memory Systems

p. 313

2. (iii) Forgetting

Major reasons: a) failure to encode b) stored memories decay c) retrieval failure d) interference:

Proactive and retroactive p. 304

2. (iii) Forgetting: Interference

p. 304

2. (iii) Forgetting: The Story of HM The most famous and studied amnesiac

Anterograde amnesia (p. 311)

2. (iii) Forgetting e) Motivated forgetting:

Freud’s concept of repression Repressed memory controversy

p. 305-308

3. Eyewitness Testimony A case of constructive memory

Discussed by professor in class Another illustration with Loftus http://www.youtube.com/watch?v=_RLvSGYxDIs&feature=fvw

Conclusion: “Memories” for non-existent objects can be implanted Memory is surprisingly unreliable

4. Improving your Memory a) Pay Attention!

And over learn b) Distributed practice

Take your time, and take time c) Engage in deep processing

Make information personally meaningful Provide examples for yourself

Link to previously acquired knowledge d) Organize information hierarchically e) Learn through several modalities

E.g. use visual imagery (2 codes is better than 1)

f) Use mnemonics (where useful) g) Minimize interference

4. Movie: Beautiful Minds...

An amazing case of perfect photographic memory. (5 min.)
