To adapt to changing conditions in the world.
26
What are the four types of learning?
1. Noticing and ignoring (sensitisation and habituation) 2. Learning what events signal (classical conditioning close back bracket). 3. Learning about the consequences of our behaviour (operant conditioning) 4. Learning from others (observational and learning).
27
What is NOT learning?
Instincts, reflexes and changes in behaviour due to fatigue.
28
What is an unconditioned response in classical conditioning?
an unlearned response that occurs naturally in reaction to the unconditioned stimulus.
29
What is a conditioned response in classical conditioning?
an automatic learned response established by training to an ordinarily neutral stimulus.
30
What is a conditioned stimulus in classical conditioning?
a previously neutral stimulus that, after becoming associated with the unconditioned stimulus, eventually comes to trigger a conditioned response.
31
What is an unconditioned stimulus in classical conditioning?
A stimulus that occurs naturally, and automatically to trigger a response
32
What is contingency?
- The predictability of occurrence of one stimulus from the presence of another. - Will depend on reliability and uniqueness. - CS must be able to predict US.
33
Appetitive means
Pleasant
34
What is contiguity?
-The connectedness in time and space of two stimuli. | Eg when two stimuli are presented together in time
35
Aversive means
Unpleasant
36
What are two main schedules of reinforcement?
- Ratio (reinforcement depends on number of responses made): Fixed or Variable - Interval (amount of time between reinforcements): Fixed or Variable
37
What are the four processes of observational learning?
1. attention 2. retention 3. reproduction 4. motivation (from reinforcement)
38
What is the definition of personality according to Burton et al. (2011)?

43
Positive reinforcement in operant conditioning?
the process of encouraging or establishing a pattern of behaviour by offering reward when the behaviour is exhibited.
44
What is positive punishment in operant conditioning?
involves presenting an unfavorable outcome or event following an undesirable behaviour.
45
What is negative reinforcement?
When a response or behaviour is strengthened by stopping, removing, or avoiding a negative outcome or aversive stimulus.
46
What is negative punishment in operant conditioning?
taking away a certain desired item after the undesired (reinforcing) behaviour happens in order to decrease future responses.
47
Hume believed...
Careful observations was the first step in the scientific approach.
48
What would most likely result in an inhibitory postsynaptic potential (IPSP)?
Chloride ions entering the cell.
49
Parkinson’s Disease is a neurological disorder associated with
Motor impairment and a reduction in the neurotransmitter dopamine.
50
The consumption of alcohol, as well as the ingestion of anti-anxiety drugs, both work to increase the activity of inhibitory neurotransmitter...
GABA
51
The neurological disease associated with the destruction of the myelin sheath of neurons is
Multiple sclerosis
52
What is a fixed radio schedule?
These deliver reinforcement after a set number of responses. (Eg rewarding real estate agent with a bonus for every five houses sold) *extinction will occur when reward is stopped.
53
What is a variable ratio schedule?
Reinforcement occurs after a variable number of responses. (Eg the probability of hitting the jackpot is constant, number of lever presses needed to hit jackpot is variable.) *most resistant to extinction
54
What is a fixed interval schedule?
Where there is a fixed amount of time between each reinforcer. (Eg being paid by the hour) *extinction will occur quickly if reinforcer is stopped.
55
What is a variable interval schedule?
Reinforced on an average amount of time that varies from trial to trial. (Eg fishing) *resistant to extinction in that behaviour will continue for quite a while after reinforcement stops.
