Memory models - Atkinson and Shiffrin

Question 1

What is memory

Answer 1

Memory is a cognitive process used to encode, store, and retrieve information.

Question 2

Reaserchers of the Multi Store Model

Answer 2

Atkinson and Shiffrin

Question 3

What model consits that the human memory has three components that hold information for a specific duration and have a specific capacity

Answer 3

Multistore memory model

Question 4

Three parts of the multistore model

Answer 4

Sensory model store
Short Term memory
Long term memory

Question 5

Sensory Model store (3 points)

Answer 5

Does not process information , only detects THORUGH senses
Hold information from 1-5 seconds
If given attention –> STM , if not –> LOST

Question 6

Short term memory 2p

Answer 6

Information stays for 30 seconds
maximum capacity 7+- chunks

Question 7

Long term memory 3p

Answer 7

Rehersal is needed to transfer information
LTM stores large amounts for indefinite periods
Unlimited capacity but problems to retrieve info

Question 8

CASE STUDY USED

Answer 8

Sperling 1960

Question 9

Aim of Sperling 1960

Answer 9

Test the iconic memory (memory of visual stimuli) part of sensory memory

Question 10

Technique and sample

Answer 10

Partial report technique
Participants were shown a grid of alphanumeric characters for 50 mili seconds

Question 11

What was the first condition and result

Answer 11

1. Whole Report –> aked to guess the 12 alphanumeric characters
   guesses 4/12

Question 12

What was the second condition and result

Answer 12

2. Partial report –> only asked to remember 1 row stated by a specific sound
   guesses 3 or 4

Question 13

Conclusion and relation of Sperling 1960 to Atkinson and Shiffrin MultiStore model

Answer 13

After being exposed to visual stimuli it stays in our memory for a short period of time. If we attend it, it goes onto our short term memory, if not, we lose it.

Question 14

Structure

Answer 14

Introduction and theory
- define memory
- Multistore memory model of Atkinson and Shiff
- 3 components, SM, STM, LTM

Study
-Sperling 1960
- Aim: test iconic memory (SensM)
- Method : partical report technique , alphanumeric grid
- 2 conditions : whole report 4/12 guess, partical report 3-4 charactes

Conslusion
How it relates to theory
After being exposed to visual stimuli it stays in our memory for a short period of time. If we attend it, it goes onto our short term memory, if not, we lose it.
