paper 1 memory definitions

Question 1

coding

Answer 1

the format in which information is stored.

Question 2

capacity

Answer 2

the amount of information that can be held.

Question 3

sensory register (SR)

Answer 3

The memory stores for each of the five senses, such as vision(iconic store) and hearing (echoic store).Coding the iconic sensory register is visual, echoic is acousitc. capacity is huge but info lasts less than half a second.

Question 4

Short-term memory (STM)

Answer 4

a limited capacity memory store. Coding is mainly acoustic. capacity is between 7+/-2 ave.duration is 18 to 30 secs.

Question 5

Long-term memory (LTM)

Answer 5

a permanent memory store. Coding is mainly semantic (meaning). has unlimited capacity (can store memories for a lifetime.

Question 6

Multi-store Model (MSM)

Answer 6

A representation of how memory works in terms of three stores called sensory register, STM, LTM. It describes how info is transferred from one store to another, how its remembered + forgotten.

Question 7

primary effect

Answer 7

the tendency to recall info presented at the start of a list better than info at the middle

Question 8

Recency effect

Answer 8

the tendency to recall info presented at the end of a list better than the start or middle

Question 9

working memory model (WMM)

Answer 9

A representation of STM. Suggesting that STM is a dynamic processor of different types of info using sub- units coordinated by a central decision making system.

Question 10

central executive (CE)

Answer 10

The component of the WMM that co-ordinates the activates of the three subsystems in memory. it also allocates processing resources to those activities.

Question 11

Phonological loop (PL)

Answer 11

the component of the WMM that processes info in terms of sound.
this includes both written and spoken material. it is divided into the phonological store and the articulatory process.

Question 12

Visuo-spatial sketchpad (VSS)

Answer 12

the component of the WMM that processes visual and spatial info in a mental space often called “inner eye”

Question 13

Episodic buffer (EB)

Answer 13

brings together material from other subsystems into a single memory rather than separate strands . also provides a bridge between working memory and LTM.

Question 14

Dual- task technique.

Answer 14

Methods used to measure the performance of the different slave systems of the WMM whilst participants perform two tasks simultaneously.
