Q

Acquisition is dependent on..

A

The strength of the CS and the US

Rescorla-Wagner Model (1972) units of associative strength are higher with a strong CS

Q

Temporal contiguity …

A

CS = US the events are close together and continuous

CS - TIME = US events are separated

Q

Extinction is…

A

When the CS is presented alone with no US.

According to the Rescorla-Wagner model this results in a weakened CR

Q

Stimulus generalisation is when…

A

Grant and Schiller (1953) Stimuli that are similar to the CS elicit a CR

Pearce and Wilson (1990) when stimuli and food has higher mean responses per minute that stimuli and no food

Q

Higher order conditioning is when…

A

A stimulus established as a CS is paired with a neutral stimulus. After the pairing, the neutral stimulus (now CS2) also elicits the CR

Q

Taste aversion

Nachman and Ashe (1973)

A

Food + lithium chloride induces sickness and therefore produces an aversion to that flavour
Experimental were give sucrose and LiCl, control given sucrose and NaCl, the controls had a much higher sucrose intake

Q

Eye blink conditioning

Kronforst-Collins and Disterhoft (1998)

A

Air puff = blink
Tone + air puff = blink
Tone = blink

Q

Watson and Rayner (1920)

A

Little Albert.
White rat + noise = fear.
Extended to all white furry things

18
Q

Behaviour therapy;

Exposure therapy

A

The patient is exposed to the feared stimulus (CS) without any consequence which leads to the extinction of the CR

19
Q

Advertising

Stuart, Shimp and Engle (1987)

A

Pairing a product with a pleasant stimulus (US) results in the product being rated favourably

20
Q

Anticipatory nausea and vomiting

Stockhorst, Steingrueberm and Klosterhalten (2006)

A

Chemo patients - the stimuli of the hop spiral lead to the feeling of nausea and vomiting

21
Q

Thorndike

A

Cats in a box. Time to escape decrease over time as the animal is more likely to perform behaviours that enable escape

22
Q

B. F. Skinner

A

Behaviour is influenced by its consequence. Positive outcome = behaviour will increase

23
Q

Reinforcement (increases response rate)

A

Positive - reinforcing stimulus arrives

Negative negative stimulus removed

24
Q

Punishment (reduces response rate)

A

Positive - aversive stimulus presented

Negative - stimulus is removed

25
Shaping is...
Reinforcing approximations of the desired behaviours
26
Animal training | Clicker training
Starts with classical conditioning | Uses operant condition to reinforce desired behaviours
27
Token economies are...
Using tokens to reward good behaviour which can be exchanged for goods in shops This is secondary reinforcement
28
Gendreau, Listwan, Kuhns and Exum (2014) | Token economies in prisons
Lead to a 54% improvement of target behaviours
29
Petry, Barry, Pescatello and White (2011) | Weight loss and tokens
More weight loss than other groups if prize draws used as tokens
30
A ratio schedule of reinforcement is...
Reinforcement after making a certain number of responses
31
An interval schedule of reinforcement is...
Response is reinforced after a specified time interval since the last reinforcement
32
Fixed Ratio (FR) is...
The required number of responses is always the same. FR=50 means 50 responses before the reinforcement This produces high rates of output similar to getting paid for a certain amount of work
33
Variable Ratio (VR) is...
The average number of responses required before reinforcement but the exact number varies. VR = 50 the average number is 50 Produces fast steady responses like a video game or slot machines
34
Fixed Interval (FI) is...
The time interval between reinforcements will be the same. FI= 50 59 seconds between reinforcements Produces slow responding. Class times
35
Variable Interval (VI) is..
The time interval between reinforcements varies VI=50 59 seconds on average Produces slow steady responding like random drug testing
36
A comparison of reinforcement schedules...
VI50 and FI50 have a lower output of responses
37
Extinction is when...
The response is no longer required so the response isn't paired with a reward. The rate of extinction depends on the schedule of reinforcement Variable schedule makes behaviour more resistant to extinction
38
Escape conditioning is...
A result of negative reinforcement | The response terminates an aversive stimuli
39
Avoidance conditioning is...
A result of negative reinforcement where the response it made to avoid the aversive stimuli
40
Habituation is...
The most basic form of learning shown by most organisms. It is the reduction in response to a repeated stimulus.
