Q

Attention

A

actively focusing on particular information while simultaneously ignoring other information

in memory formation, this process determines which info will be processed further within short-term memory.
in observational learning, learner must watch a model closely to remember their behaviour to replicate it later

Q

Classical conditioning

A

type of learning where a stimulus that naturally evokes a specific response is paired with a neutral stimulus that doesn’t usually produce this response.
an association occurs between the neutral stimulus and unconditioned stimulus during this acquisition stage
after conditioning, this stimulus alone will elicit the response that it formerly didn’t

Q

Consolidation theory

A

theory that proposes that for new information to be transferred effectively from short-term to long-term memory, there needs to be a period where these memories can fortify or stabilise without being disrupted.
during this time, physical changes occur at the neuronal level as the brain organises and restructures info to enable permanent storage of the new info

54
Q

Rehearsal

A

process for actively renewing information in short-term memory in order to retain it for a longer period of time

55
Q

Reinforcement

A

any object or event administered after a response which strengthens and increases the likelihood of that response recurring over time

56
Q

Reinforcer

A

often referred to as a rewards, any event or consequence that strengthens the response it follows and increase the likelihood of that response occurring again

Q

Retrieval cues

A

internally or externally generated stimuli that assist the process of locating and recovering information stored in memory

62
Q

Semantic memory

A

form of declarative (explicit) long-term memory which stores specialised factual information about the world, including general knowledge and the meaning of words

63
Q

Semantic processing

A

the deepest level of processing information by creating meaningful associations to understand the items to be remembered

64
Q

Sensory memory

A

aka sensory register
stage of memory that has a large capacity for unprocessed info
but is only able to momentarily preserve extremely accurate image (‘traces’) of sensory info, just long enough for relevant details to be attended to and transferred to short-term memory.
two types of sensory memory that have been most extensively explored are iconic (visual) memory and echoic (auditory) memory

a memory system with limited storage capacity of seven plus or minus two items and duration of about 18-20 seconds
where currently used info is retained
allows the manipulation of info contained in sensory or long-term memory

66
Q

67
Q

Social learning theory

A

an approach to describing and explaining operant conditioning in terms of 3 steps:
