Behaviourism (AP P2) Flashcards
1
Q
What is classical conditioning?
A
- Learning through association
- First demonstrated by Pavlov: showed that a neutral stimulus can come to elicit a new learned (conditioned) response through association
2
Q
Main findings of Pavlov’s research
A
- 1927
- Showed how dogs could be conditioned to salivate to the sound of a bell if the sound was repeatedly presented at the same time they’re given food
- Dogs learned to associate the sound of a bell (stimulus) with the food (another stimulus) and would produce the salivation response every time they heard the sound
3
Q
What is a neutral stimulus (NS)?
A
- An event that does not produce a response
- White rat
4
Q
What is an unconditioned stimulus (UCS)?
A
- An event that produces an innate, unlearned reflex response
- Loud noise
5
Q
What is an unconditioned response (UCR)?
A
- Innate, unlearned reflex behaviour that is produced when exposed to an unconditioned stimulus
- Fear of the loud noise
6
Q
What is a conditioned stimulus (CS)?
A
- An event that produces a learned response
- White rat
7
Q
What is a conditioned response (CR)?
A
- A learned behaviour that is produced when exposed to a conditioned stimulus
- Fear of the white rat
8
Q
What is timing?
A
Stimuli must be presented at the same time otherwise they won’t be paired
9
Q
What is stimulus generalisation?
A
Generalise stimulus to things that are similar to it
10
Q
What is extinction?
A
- Reversing the conditioning by presenting the conditioned stimulus without the unconditioned stimulus
- Over time the association will be broken
11
Q
What is spontaneous recovery?
A
- Once extinction has occurred, the connection suddenly recovers spontaneously
- Link between CS and UCS is made much more quickly
12
Q
What was the Little Albert Experiment?
A
- Conducted by Watson and Rayner 1920
- 9 month old infant shown a white rat/rabbit/monkey/various masks, was unemotional (no fear)
- Hammer being struck against a steel bar caused a fear response (crying)
- White rat and sound presented at same time 7 times over 7 weeks, caused a fear response
- When the rat was presented without the sound, a fear response still occurred
- Albert also developed phobias of objects which shared characteristics with the rat (stimulus generalisation)
13
Q
What is operant conditioning?
A
- Form of learning in which behaviour is shaped and maintained by its consequences
- Includes positive reinforcement, nagative reinforcement and punishment
14
Q
Skinner box experiment
A
- Conducted experiments with rats/pigeons in specially designed cages called skinner boxes
- Every time the rat activated a lever (or pecked a disk in the case of the pigeon) within the box it would be rewarded with a good pellet
- The animal would continue to perform the behaviours
- Animals could be conditioned to perform the same behaviour to avoid an unpleasant stimulus e.g. an electric shock
15
Q
What is positive reinforcement?
A
- Receiving a reward when a certain behaviour is performed
- e.g. praise from a teacher for answering a question correctly in class
