Q

Describe the experiment of Pavlov’s dogs

A

Each time Pavlov’s dog was fed and the amount of saliva produced was measured and a bell was rung
This was repeated many times
The bell was rung and the amount of saliva produced was the same as the amount with the food present

Q

Give a study about classical conditioning

A

Watson & Rayner (1920)

To see if the emotional response of fear could be conditioned in a human being

Albert was 11 months old, he liked white rats and had no fear of white furry objects, the rat was shown to Albert and as he reached for it, a metal bar was hit with a hammer behind him, this was done several times

When the rat was presented, Albert screaming and tried to get away even though the metal bar was not hit, he also screamed in the presence of a Santa mask

Fear responses could be learnt and very young children can learn in the way suggested by classical conditioning

Q

Evaluate the classical conditioning study

A

This was very unethical to scare the child in this way

The study only used one child so they needed more evidence to generalise the results

Q

Describe the classical conditioning schedule

A

Before conditioning: there is an UCS and a UCR
During conditioning: there is CS with the UCS and a UCR
After conditioning: the behaviour is learnt so only the CS is needed to trigger the response which is now called the CR

Q

Those that are punished are not usually repeated

Q

What did Thorndike do to prove the law of effect?

A

He placed a cat in a box where the door would open if it pulled a string
He timed how long it took for the cat to open the door 40 times in a row
The cat learnt how to open the door and when it did, it was rewarded by the door opening
This caused the cat to open the door faster and faster as time went on

Q

What is punishment?

A

A stimulus that weakens behaviour because we try to avoid it

17
Q

What is reinforcement?

A

A consequence of behaviour that encourages or strengthens that behaviour

18
Q

What is positive reinforcement?

A

When a reward is presented to reinforce a behaviour

19
Q

What is negative reinforcement?

A

When an unpleasant experience is removed to reinforce a behaviour

20
Q

What is behaviour shaping?

A

Changing behaviour in small steps

21
Q

What did Skinner do to discover reinforcement?

A

He put a rat in a box and when the rat touched a button, food was given to it
Over time, the rat learned to push the button as soon as it entered the box
He also put the rat into a box that gave the rat electric shocks and when it pushed the button, the shocks stopped
This negative reinforcement had the same effect as the positive reinforcement

22
Q

What is flooding in terms of learning?

A

A treatment for phobias that immediate exposure of the person to the feared thing until there is no fear response

23
Q

What is systematic desensitisation?

A

A treatment for phobias in which the person is told to relax and gradually exposed to the feared thing

They have to become relaxed on each stage before moving on

24
Q

What is the hierarchy of fears?

A

A series of feared events ranked from least frightening to most

25
Q

What is aversion therapy?

A

A treatment for addictions which makes the addict have an extremely negative reaction to the substance

26
Q

What is token economy?

A

Giving people either primary or secondary reinforcers as a reward for doing the things that you need them to do

27
Q

What is the difference between a primary and a secondary reinforcer?

A

A primary reinforcer is something that is needed to survive like food
A secondary reinforcer is something that can be cashed so that rewards can be purchased from a selection of possible rewards

28
Q

What is the Garcia effect?

A

When one incident is enough to produce a conditioned stimulus and response
