1

Memory

Ability to store and retrieve info over time, reconstructive/collaborative process

2

What are the 3 functions of memory?

Encoding, Storage, Retrieval

3

Encoding

we transform what we perceive/think/feel into an enduring memory

4

Storage

process of maintaining info in memory over time

5

Retrieval

process of bringing to mind info that has been previously encoded/stored

6

What are the 3 major ways to encode?

Elaborative/semantic encoding, visual imagery encoding, organizational encoding (codes do NOT have to conform to original stimulus)

7

Elaborative/semantic encoding

Process of actively relating new info to knowledge that is already in memory

8

Visual imagery encoding

Process of storing new info by converting it into mental pictures, can improve memory

9

Organizational encoding

Process of categorizing info according to the relationships among a series of items

10

The lower left frontal lobe is active during:

semantic recording

11

The occipital lobe is active during:

visual encoding

12

The upper left frontal lobe is active during:

organizational encoding

13

Sensory memory (also give two types)

Storage that holds sensory info for a few seconds or less Iconic/Echoic memory

14

Iconic memory

fast-decaying store of visual info (1 second or less)

15

Echoic memory

fast-decaying store of auditory info (5 seconds or less, eg: last few words of a sentence)

16

Short-term memory (STM) (3 types)

Storage that holds non-sensory info for 15-20 secs (can hold about 7 items) Rehearsal, Chunking, Working Memory

17

Rehearsal

process by keeping info in STM, mentally repeating

18

Chunking

combining small pieces of info into larger clusters, more easily held in STM

19

Working Memory

active maintenance of info in STM

20

Mnemonic

memory aid that uses vivid imagery

21

Maintenance Rehearsal

WE can extend info by rehearsing/repeating out loud

22

Elaborative Rehearsal

focus on meaning/relate info to other things you already know

23

Central executive

working memory subsystem, decides what working memory pays attention too

24

Visual-spatial pad

stores and processes info in a visual/spatial form

25

Long-term storage

no known capacity, people recall items even if they haven't thought of them for years

26

Describe the flow of info through memory system

27

Explicit Memory

Act of consciously or intentionally retrieving past experiences, requires recognition

28

Implicit Memory

Influence of past experiences on later behavior, even w/o effort or awareness

29

Priming

Eg of implicit memory, enhanced ability to think of a stimulus aafter bein exposured to the stimulus; less cortical activation (perceptual and conceptual priming)

Tl;dr more likely to remember something after recently seeing it

30

Procedural Memory

Gradual acquisition of skills as a result of practice, or “knowing how” to do things

e.g. reading music, playing an instrument
