Q

Differentiate between unconditioned association and conditioned association.

A

Unconditioned association is natural and unlearned, while conditioned association is established through pairing

Q

What does Thorndike’s law of effect state?

A

When a response to a stimulus is associated with satisfying effects, the response is more likely to be repeated in that context

Q

What is the difference between primary and secondary reinforcers?

A

Primary reinforcers satisfy biological needs; secondary reinforcers acquire reinforcing qualities through association with primary reinforcers

Q

What is the renewal effect in conditioning?

Q

What is a variable-ratio schedule?

A

The reinforcer is given after a number of nonreinforced responses that varies around a predetermined average

23
Q

What is a fixed-interval schedule?

A

The reinforcer is given for the first response that occurs after a fixed time interval has elapsed

24
Q

What is a variable-interval schedule?

A

The reinforcer is given for the first response after a length of time has elapsed that varies around a predetermined average

25
What are the two types of reinforcement?
* Positive reinforcement * Negative reinforcement
26
Define escape learning.
A responding pattern develops because it stops an unpleasant experience
27
Define avoidance learning.
A responding pattern develops because it prevents an unpleasant experience from happening
28
What is positive punishment?
The presentation of an aversive stimulus aimed at reducing a particular response
29
What is negative punishment?
The removal of a rewarding stimulus aimed at reducing a particular response
30
What is observational learning?
How an organism responds is influenced by observing others
31
Who is a significant theorist in observational learning?
Albert Bandura
32
What are the four key processes in observational learning?
* Attention * Retention * Reproduction * Motivation
33
What is Learning
a relatively durable change in behaviour or knowledge do to experience mostly done on animals befor
34
what is conditioning
learning connections between events that occur in an organzism enviorment 1 CLASSCIAL = pavllovian 2. OPERANT
35
Classical Conditioning
stimulus acquires the capacity to evoke a response thta was orginaly evoked by another "psychic reflexes" - pavlov referred to them as a trial
36
UCS UCR CS CR
U - Unconditioned - natural, unlearned assocation UCS - stimuls that evokes an UCR **without prior** condiitioning UCR - **unlearned** recation to unconditioned stimuls **without previous conditioning** C - condidiiton - conneciton link/ paring CS - **previously neutral response** CR - learned response to **CS due to conditiongin**
37
CR is usually weaker than
UCR
38
Operant Conditioning
responses **controlled** by their consequences. insturmental learning
39
Thorndikes law of
EFFECT - when a response has satifying effects the response is more likley to be repeated with a gradual decline in response time. - indicating learning
40
Princiople of Reinforcement
When something is reinforcing it must have an increase in response time.
41
Emited vs Elicited
emitted or sent forth **voluntarily** elicited by punsihment or negative reinforcement
42
Skinner box
controls the reinforcement contingencies - cumlulative recorder
43
Reinforceer
Primary - sex, food, warmth secondary - events that acquire meaning and reinforcing characteristics through association with primary reinforcers.
44
Processes - Conditioning - 1
1 Acquisition - **Classical** CS and UCS are paired over time what is called stimuli salience . TIME/SPACE **shaping** the reinformenc tof closer and closer approximations of desired response. Shaping GUIDES through REPETITION
45
Processes - Conditioning - 2
EXTINCTION **classical** CS is presented alone until CR doens't work - Learning to forget as adaptive behavour **operant** - once reinfocement is stopped a response stops Som respones can be challenging to get rid of. in CLASSICAL there can be spontaeous recovery... or in OPERANT we say resistant to Extinction There can be renewal effect were if acquisition occurs in one context extinction in another is can come back. This as implicaitn in treatedmtn of phobias and extinction therapy
46
Processes - Conditioning - 3
STIMULUS Gernalization **classical** CR is elicited by a new stimuls that resemble the first ** little albert** **operant** when a new stimuls resmebres the old can have an increasing rate..... can be quantifiied by a generalization rate.
47
Processes - Conditioning - 4
Stimulus Discrimination **CLASSICAL** CR is not elicted by resemblihg CS **OPERANT** Response doesn't increase
48
OPERANT timing
a immediate reinforcement makes an effect more likely to happen. Delay means it will take longer
49
Schedules of Reinforcement in OC
ratio - number of times FIXED-RATIO and VARIABLE-RATIO (hacks dopemine) FIXED-INTERVAL and VARIABLE-INTERVAL
50
Types of ReINFORCEMENT
POsitive - somethign rewarding - buying a video game NEGative - removal of soemthing unpleasant Escape and AVOIDANCE -Escape ends negative experience - Avoidance prevent unpleasant from happening
51
TYPES of Punishment
POSTITVE - presentation of averisve stiumlus NEGative - removal of rewarding stimulus
52
53
Observational Learning
infulued by observing MODELs (others) Albert Bandura ob learning argues reinforcement increases likilihood a response is performed (vs learned) 1. Attetion 2Retention 3. Reproduction (being able to reproducer) 4 Motivation (you must be motivated to produce the response)
