Q

What is learning?

A

Learning is a process based on EXPERIENCE that results in a relatively consistent change in behaviour of behaviour potential
(not due to maturation of the brain but may be dependant on brain maturation-e.g. for babies)
(can do things that change attitude but this may lead to change in behaviour,) (may take multiple times to cause a change)
Underlines our behaviour
Not all learning is good
-Learning occurs through experience
Classical and operant conditioning are the two ways in which we learn

Q

What is classical conditioning?

A

The learning of a new association between two previously unrelated stimuli
A neutral stimulus becomes associated (or paired) with a stimulus that causes a reflexive behaviour
We learn that a stimulus predicts a certain event and we respond accordingly

Q

What is Acquisition (during conditioning)?

A

the process by which the conditioned response (CR) is first elicited

  • CS and UCS must be paired several times (except with being sick from something e.g. food-strong response and long lasting)
  • Timing is critical - pairing must be closely enough in time to be perceived as being related

25
What is Reinforcement Contingency?
To be most effective, the reinforcement should be contingent (dependent) on a desired response
26
What are the Consequences of behaviour?
Reinforcement | punishment
27
What is the Reinforcement consequence of behaviour?
a stimulus that occurs after behaviour and INCREASE the likelihood that the behaviour will occur in the future
28
What is Punishment consequence of behaviour?
a stimulus that occurs after behaviour and DECREASES the likelihood that the behaviour will occur in the future
29
What is positive reinforcement?
the presentation of a pleasant stimulus after a behaviour | e.g. money pid for coming to work
30
What is negative reinforcement?
the removal of an unpleasant stimulus after a behaviour e.g. aspirin removes headache, greater tendency to do it again nagging to do DIY, stop when do it seat belt sound turn off when click in, greater tendency to put in next time
31
What is positive punishment?
the presentation of an unpleasant stimulus after a behaviour e. g. Fail - may no be partying again before exam, instead studying next time - ripping hair off
32
What is negative punishment?
the removal of a pleasant stimulus after a behaviour | e.g. Time out or grounded by taking away privileges(phone or Wifi)
33
What does Positive mean?
Adding a stimulus
34
What does Negative mean?
Removing a stimulus
35
What are the two types of reinforces?
Primary reinforcers | Secondary reinforcers
36
What are Primary Reinforcers?
Biologically determined | (food)- aids survival
37
What are Secondary Reinforcers?
Token economies, money, praise can get primary from it (money) - buys food-the primary reinforcers
38
What are the three important components of reinforcers?
- Immediate vs. delayed reinforcement (e.g. degree you desire) - magnitude of reinforcement(lollies lose effect over time) - consistency and repetition or reinforcement (sick be sufficient)
39
What is superstitious behaviour?
idiosyncratic association between behaviour and their consequences - pigeon twirling around at 5 when food time, accidentally associated with getting food - wear same boots to exams, like last time when you got a A+
40
What is shaping?
a procedure which a complex behaviour is trained by reinforcing closer and closer approximation of the desired response - Progressively training - dolphins jumping through hoops - dogs through complex course - builds complex chain of behaviour
41
What are the 3x examples of Progressive training?
``` to do a complex dance routine a dog to fetch the paper animals to assist people with disabilites -dolphins jumping through hoops -dogs through complex course - builds complex chain of behaviour ```
42
What is the effect of Extinction in operant conditioning?
A behaviour reduces in frequency when reinforcement is not given For instance, a child stops throwing tantrums when his/her parent's ignore the bad behaviour, walk away child learns tantrum won't cause parents to come back, therefore extinction of behaviour
43
What are the two schedules of reinforcement?
Continuous reinforcement schedules Intermittent/partial reinforcement schedules vs Ratio (# to get response) and Intervals (time)
44
What is Continuous reinforcement schedules?
reinforcer is obtained after every response
45
What is Intermittent/partial reinforcement schedules?
reinforcer is NOT obtained for every response
46
What are the two types of ratios?
Fixed ratio | Variable ratio
47
What is a Fixed ratio?
reinforcer is delivered for the first response made after a fixed number of responses e.g. factory worker paid per toy made brief pauses after each reinforcer is delivered - steep, bumpy blue line
48
What is a Variable ratio?
Reinforcer is delivered for the first response made after variable number of response whose AVERAGE is predetermined e.g. gambling machine no pauses after each reinforcer is delivered- steep, flat black line e.g. waiting for taxi, average time to rate is 10min
49
What are the two types of interval schedules?
Fixed interval | Variable interval
50
What is a fixed interval?
reinforcer is deliver for the first response made after a fixed period of time e.g. salary Few responses after each reinforcer is delivered - less steep, bumpy, red line
51
What is a Variable interval?
reinforcer is delivered for the first response made after a variable period of time whose AVERAGE is predetermines e. g. fishing - less steep , flat, green ling
52
What is the ABC of behaviour modification?
``` A= Antecedent B= (target) Behaviour C= Consequence ```
53
What is the A in the ABC of behaviour modification?
Antecedent (triggers) Events that typically precede (evoke) the target behaviour(which we are trying to modify)
54
What is the B in the ABC of behaviour modification?
(target) Behaviour | the behaviour that you're trying to modify
55
What is the C in the ABC of behaviour modification?
Consequences | Reinforcers the maintain the target behaviour
56
What happens if the C in the ABC of behaviour modification involves punishment?
Consequences | Punishment (unfavourable outcomes) that suppress the desirable target behaviour
57
Which parts of the ABC behaviour chain are variable?
``` A = control/change antecedents C= change consequences ```
58
What is some medical applications of operant conditioning?
behavioural therapy Parent management training (e.g. Incredible Years, Tripple P) Encouraging behaviour change
59
What are some examples of encouraging behavioural change in medical applications of operant conditioning?
Some used with health policies ``` Not smoking Reducing drinking Not drinking and driving Exercise programmes and healthy nutrition Adherence to treatment ```
60
What is an association of?
association between stimulus, response (behaviour) and its consequence
61
Overall what is classical conditioning (learning)?
Previously neutral stimulus elicits a response after being paired with UCS
62
Who is Pavlov?
Nobel price recipient for his research in medical physiology | stimuli - light or sound to be paired for
63
What are examples of classical conditioning?
jingling of bell get dogs tail wagging for walk | getting can can opener gets cat excited as associates it with food
64
What does "conditioned" mean?
learnt stimulus
65
What is an exception to acquisition?
Stimulus (such as eating food and being sick) can occur just once CS and UCS doesn't have to be paired multiple times in this case strong and long lasting effect
66
What does the difference in timing of "conditioning" result in?
difference in the time the behaviour is acquired
67
What is a typical condition?
delayed condition
68
What can classical conditioning result in?
Conditioned Emotional Response - Little albert - ethical problems -horribel noise - 7 pairings cause albert to start crying on sight on rabbit
69
What is an example of conditioned emotional response?
Watson and Rayner's study with Little Albert (1919) | -this many explain acquisition of simple phobias
70
What may explain the acquisition of simple phobias?
Conditional emotion Response experiment by Watson and Rayner on Little Albert and making noises 7 time to pair Albert with fear associated to sight of rabbit
71
What is an example of Negative Reinforcement with Friday 13?
Cross road with no cat = fine | Negative reinforcer = removal of unpleasant stimulus = not run over
72
What does ABC behaviour modification suggest?
what causes someone's behaviour to occur
73
What is an example the ABC behaviour modification in the lecture?
``` A = cat picture on slides - trigger to do target behaviour B = target behaviour was to get up and dance C = consequence was getting lolly, say well done - pleasant consequences - students getting reinforced ```
74
What is a modification to the example of ABC behaviour modification in the lecture?
A = different picture on slides - cool dog trigger to do target behaviour B = target behaviour was to get up and dance - C = consequence was tell them to sit down, feel embarrassed - unpleasant consequences - students getting reinforced -behaviour will change
