16
Q

How much information get passed between sensory and STM

A

Only selected images and sounds are encoded into STM

17
Q

How much can be stored within STM

A

Only +-7 items can be stored at one time

18
Q

How is information deleted from STM

A

Displacement and Decay

19
Q

DIsplacement definition

A

Pushing out old information by new information

20
Q

Decay definition

A

Breakdown of memory trace

21
Q

Serial position effect

A

Objects earlier in the list can be repeated for longer, objects later in the list were said earlier, objects in the middle are forgotten

22
Q

CHUNKing definition

A

Put a large group of information into smaller, more memorable amounts

23
Q

How can information be transferred from STM to LTM

A

Rehearsal, Organisation, Elaboration

24
Q

Function of neurons

A

Transmit electric signals (nerve impulses)

25
Q

What is a synapse

A

Junction between an axon of one cell and a dendrite of another

26
Q

Function of neurotransmitters

A

Relay chemical messages from nerve to nerve within and out the brain

27
Q

Excitatory signals cause…

A

An increase in action (muscles contract)

28
Q

Inhibitory signals cause…

A

A decrease in action (causes muscles to relax)
