Learning can be defined as a relatively permanent change in behaviour (or knowledge) that results from past experience.

Q

Imagine a lab grown brain is connected to the world for the first time. Would it be able to understand anything

A

No, it has no prior learning. It has spent its time in isolation. It would just be confused

Q

What are the three main types of learning

A

Simple - Habituation and sensitisation
General - Classical conditioning - event consequence
Operant conditioning - Action consequence
Specialised - Imitation, think, test, revise, insight, language, imprinting

Q

Why are we focussed more on general learning

A

Because it can be used in many situations and it is flexible. It allows learning in new situations eg cats opening fridge door

Q

What are sea slugs famous for

A

Can study learning and memory in a simple system. They have a very simple nervous system with 20, 000 neurons

Q

What are some differences between simple learning and other types of learning

A
  • Simple learning tends to be one biological system eg gill and siphon
  • Simple learning often involves reflexes
    *Simple learning is usually involuntary
    *Simple learning does not last long
    *Change in behaviour is usually of a very restricted form

A

When you have an a ha moment. Suddenly you know the answer.

Q

What are the two main things that differentiate specialised learning from both general and simple learning

A
  • It is restricted to certain species eg humans, apes
  • It occurs in specific times in animals development

Q

Give an example of event then consequence learning

A

If a dog hears a bell and gets fed eventually it will salivate to the sound of the bell. It has paired the bell with the food. The bell is the event, food is the consequence

Q

Give an example the illustrates Thondike’s effect

A

Cats in cages learnt that pushing a button would let them escape. They got faster at escaping over time as they wanted to get out

Q

Why does Skinner think we do not have free will

A

It is our history of learning that dictates our behaviour. We don’t have a choice for our behaviour

16
Q

What is shaping

A

When you reward something for coming close to a desired behaviour. You then reward for behaviour that is gradually closer to what you want until you get desired behaviour

17
Q

What is the difference between action consequence and event consequence learning

A

One starts with an event the other an action

18
Q

Consequences can be both what…..

A

pleasant or unpleasant

19
Q

If the chance of food occurring with the tone is the same as the chance of the food occurring when there is no tone will you get learning

A

No learning only occurs when you can predict the consequences. The chance of food needs to be greater or lesser with or without the tone.

20
Q

If the chance of food occurring with no tone is greater than the chance of food occurring when there is tone will you get learning

A

Yes, it is predictive that tone means absence of food. Inhibitory learning

21
Q

If the chance of food occurring with a tone is greater than the chance of the food occurring when there is no tone will you get learning

A

Yes, you can predict that tone means food.

22
Q

What is extinction

A

When a previously learned response stops because the reward is not given

23
Q

An animal is presented with a tone, followed by a shock. Identify the CS and the US

A

Conditioned stimulus is the bell, the unconditioned stimulus is the shock

24
Q

An animal is present with a ticking metronome followed by sugar pellets. ID the CS and the US

A

Conditioned stimulus is the metronome, the unconditioned stimulus is the sugar pellets

25
In action consequence learning, what is an intermittent reinforcement schedule
When not every desired action is rewarded, only rewarded some of the time
26
In action consequence learning if an animal is rewarded on average say every 5th response what type of reinforcement schedule is being used
Variable ratio schedule
27
What are the four different types of reinforcement schedule
Fixed interval ratio- reward is given after set amount of time Variable interval ratio - reward is given after a variable interval of time Fixed ratio schedule - Reward is given after a certain number of responses Variable ratio schedule - Reward is given after a variable number of responses eg poker machines
28
Operant behaviour is what kind of behaviour, while classical is what
Operant behaviour is voluntary Classical is involuntary or reflex behavours eg salivating, eye blink
29
What are the four types of behaviour consequence relationships
positive reinforcement eg chocolate for behaving positive punishment eg smacking a child for misbehaving Posititives have something added Negatives something taken away Punishment decreases behaviour Reinforcement increases behaviour negative reinforcement eg taking panadol for a headache. Get rid of headache by adding something negative punishment - eg license is removed for speeding
30
What are the responses to the four reinforcement schdules
Fixed interval - Always at certain time, Moderate response with pauses after reinforcement eg cheap tickets on Tuesday Variable internal - Different times, Moderate but steady response rate eg cheap petrol, fill up when cheap Fixed ratio - Fixed responses - High response rate with pauses after eg pay slip Variable ratio - Variable responses - High response rate and steady eg poker machine
31
Describe the graphs for reinforcement schedules
Variable time and responses have smooth lines Varible response is the best Fixed time and responses have scolloped lines Fixed time has more curvy lines
