Dopamine

- a neurotransmitter in the brain
- 5 different dopamine receptors on the synapse
- DR04 coded for with 18 alleles - some of the alleles found links to ADHD/obesity/drug addict
- still in testing

1

Benefits of social behaviour

- hierarchy through grooming
- find food sources & share in a group
- protect each other from predators
- increase chances of mating
- learned behaviour

2

Social relationships

- the relationship between different members of a group

3

Taxes

- a directional response in movement either towards or away from a stimuli

4

Kinesis

- a non-directional response in which the animals rate of movement is affected by the strength of stimuli
- ie woodlice- increased movement due to increased humidity

5

Escape reflexes

- ie worms
- have wide neurones
- if touched -> muscles contract -> very rapid withdrawal into burrow

6

Innate behaviour

- as a pattern of inherited pre-set behaviour that does not require learning or practice

7

Learned behaviour

- behaviour that has been modified by experience

8

Insight learning

- wolfgang kohler
- chimps stacked boxes to reach bananas
- an animal puts together 2 or more things its learned to solve a problem and gain a reward

9

Latent learning

- learning that occurs without an obvious reward
- and which reward is found later in different circumstances

10

Associative learning

- learns to associate a stimulus that was previously nothing -> to a reward
- increasing chances of survival

11

Reinforcer

- rewarding a result

12

Operant learning

- animals learn to carry out a behaviour to gain a reward or avoid a punishment
-ie skinners box
- accidentally pressed lever = reward
- realise so press lever more often

13

Classical conditioning

- pavlov + pavlovs dogs
- learn to associate 1 stimulus with another stimulus & respond to the learned stimulus
- ie dogs salivate = reflex
- unconditioned stimuli = smell
- conditioned stimulus = bell
= a conditioned reflex

14

Imprinting

- a modification of behaviour that happens in a relatively short period of tine early in an animals life
- ie recognising a mum - tricky in captivity

15

Habituation

- where an animal learns not to respond to a repeated stimulus
- saves energy
