Q

what are reflexes

A

inevitable, involuntary responses to stimuli
most reflexes are controlled by nervous system circuits located in the spinal cord and brainstem
- before we had more hair and in times were we would respond to stress or cold our goosebumps would raise the hairs to make us seem bigger and to stay warm but now that we don’t have this = decreases reflex

Q

what are instincts

A

also called fixed action patterns
they are inborn patterns of behaviour elicited by environmental stimuli
- once they begin the instinctive behaviours run until completion
more complex and require more neurons

Q

explain associative learning

A

occurs when we form associations or connections between stimuli, behaviours or both
predict the future based on past experiences
1. classical conditioning = forming associations between pairs of stimuli that occur sequentially in time
- sees a bee and gets stung - now you know what bees do
- connected to Pavlovian conditioning
-explains a lot of our learned emotional responses to our environment
2. operant conditioning = forming associations between behaviours and their consequences
- parking illegally and getting a ticket so now u will pay attention more next time

Q

explain nonassociative learning

A

involves changes in the magnitude of responses to a single stimulus rather than the formation of connections between stimuli
1. habitation = reduces our reactions to repeated experiences that have already been evaluated and found to be unchanging and harmless
- a mother is used to her kids screaming but someone who doesn’t have kids will not be
2. sensitization = increases our reactions to a range of stimuli following exposure to one strong stimulus
involved in a car accident, may make u sensitive to loud sounds
- habituation occurs in response to milder stimuli whereas sensitization occurs in stronger stimuli

Q

what is the difference between conditioned responses and unconditional responses

A

CRs VS UCRs
CRs = they are learned reactions
UCRs = don’t need to be learned - they a[[ear without prior experience with a stimulus
- salivating when food is put in your mouth

Q

what is acquisition

A

refers to the development of conditioned responses (a learned response)
- requires contiguity or proximity in time between the CS and the UCs
if CS occurs long BEFORE the Ucs the organism may not view the 2 stimuli as related
- this requires a correlation between the CS and the UCS

Q

what is extinction in classical conditioning

A

when the UCS no longer follows the conditioned stimulus
- when the consequence no longer follows the learned behaviour
when the dogs are exposed to a ticking sound but no food = stop salivating

Q

what is spontaneous recovery

A

when the dogs undergo a ticking sound but no food is means that they stop salivating but it doesn’t mean they forget - it means they are learning that this CR (ticking) no longer predicts food - but it may take several session for this new learning to replace the old
- this only works after periods of rest

Q

what is generalization

A

the tendency to respond to stimuli thay are similar to an original conditioned stimulus (CS)
- someone scared of bees may also be scared of wasps and hornets

Q

what is the definition of discrimination

A

counteracting our tendency to generalize is another learning process
- this allows us to make fine distinctions between the implications of stimuli
- when you present a dog with a high tone and they always get food but with a low tone they don’t get food
the dog will salivate for both sounds because of generalization but then they will learn to differentiate/discriminate between the two stimuli

Q

what is higher-order conditioning

A

a conditioned response can occur in response to stimuli that predict the conditioned stimuli
- allows us to make more distant predictions about the occurrence of significant events
- person bitten by a dog shows fear the next time he sees a dog because dogs (CS) and now associated with the pain (UCS)

20
Q

what is latent inhibition

A

the slower learning that occurs when a conditioned stimulus (CS) is already familiar compared to when the CS is unfamiliar
- when you are already familiar with the CS it will take a longer amount of time to learn to respond to it
the effects are not seen right away
if you eat pizza all your life and suddenly one time you get sick after eating one you wont make an association with pizza and sickness
but if you eat chocolate ants one time an get sick you will 100% make the association with sickness and ants

21
Q

contiguity and contingency

A

closeness in time and the correlation between the CS and the UCS

22
Q

T/F learning occurs faster when you are surprised

A

true
- depending on how surprising the association between the CS and the unconditional stimulus (UCS)
- early in training = rapidly
- later in training = the gains in conditioning strength level off because the association between the 2 are now familiar = not surprising

23
Q

what is the exposure therapy/flooding

A

treating phobias by exposing ppl to their fear stimuli in a manner that is safe until they no longer respond = extinction
- ppl find this to be traumatic

23
Q

T/F fear can result from classical conditioning

24
Q

what is aversion therapy

A

one form of counterconditioning
- it can be used to replace inappropriate positive reactions to a stimulus with negative reactions
- when CS formerly paired with pleasurable UCS is instead paired with an unpleasant UCS
- ex: replacing a compound in tobacco to make it taste bad, helps smokers quit

25
Q

systematic desensitization

A

it is a variation of counterconditioning used to treat fear - where people relax while being exposed to stimuli that fear them
first, they are trained to achieve a state of physical and mental relaxation - once achieved, the fear stimulus is gradually introduced

26
Q

latent inhibition????

A
  • a slower development of CRs to a familiar CS than to an unfamiliar CS
  • EX: a Canadian forms a taste aversion faster to fruit bat pie than to hamburgers
27
Q

what is operant or instrumental conditioning

A

the association between a behaviour and its consequences
- organisms operate on their environment and their behaviour is often instrumental in producing an outcome
- involves voluntary behaviours like walking to class or waving to a friend

28
Q

what are the four classes of consequences

A

positive reinforcement
negative reinforcement
- reinforcements increase their behaviour
positive punishment
negative punishment
- punishments decrease behaviours

29
Q

explain positive reinforcement

A

increases the freq of its associated behaviour by providing a desired outcome
- teaching a language with candy as a positive reinforcement
- everyone has a unique effective reinforces
- to determine what a person’s positive reinforcement is use the Premack principle which states that whatever a person is spending the most time and energy on is something that is the most important to them

30
Q

what are primary reinforcers vs secondary reinforcers

A

primary - effective because of their natural role in survival such as food
secondary - also called conditioned reinforcers - they gain their value and ability to influence behaviour from being associated with other things we value

31
Q

explain negative reinforcement

A

involves the removal of unpleasant consequences from a situation to increase the freq of an associated behaviour
- increases the freq of behaviours that allow an organism to avoid, turn off, or postpone an unpleasant consequence = escape/avoidance behaviours

32
Q

positive vs negative punishment

A

Positive = applying aversive consequence that reduces the frequency of or eliminates behaviour
Negative = the removal of something desirable

33
Q

what are the 3 conditions that you must meet for punishment to have an effect on behaviour

A

significance - they have to matter to the person
immediacy - immediate punishments rather than delayed
consistency - uniform application

34
Q

what is partial reinforcement

A

the reinforcement of a desired behaviour on some occasions but not others
- ratio schedules
- interval schedules

35
Q

explain fixed ratio schedule - partial reinforcement

A

reinforcement occurs following a set number of behaviours
continuous reinforcement = 1 FR
2 behaviours for 1 reinforcement = 2 FR

36
Q

explain variable ratio schedules

A

a schedule of reinforcement in which reinforcement occurs following some variable number of behaviours
- the number of behaviours is allowed to fluctuate around some average amount
- casino slot machines

37
Q

what are fixed interval schedules (FI)

A

a schedule of reinforcement in which the first response following a specified interval is reinforced

38
Q

what are variable interval schedules

A

a schedule of reinforcement in which the first response following a varying period is reinforced
- interval needed - 2 mins

39
Q

partial reinforcement effect in extinction

A

the outcome when you have more rapid extinction after continuous reinforcement compared to partial reinforcement

40
Q

what is the method of successive approximations or shaping

A

a method for increasing the frequency of behaviours that never or rarely occur
- making kids use table manners
- teaching complex behaviours = chaining = breaking down the behaviour into manageable steps

41
Q

what is latent learning

A

learning that occurs in the absence of reinforcement

42
Q

what is the token economy

A

application of operant learning
where tokens can be exchanged for other reinforcers are used to increase the frequency of desirable behaviours
- speeding policy and demerit points

43
Q

what is observational learning

A

ability to learn by watching others
- parents, teachers
both positive and negative can be influenced by observation

44
Q

what was Albert Bandura’s work on

A

contributions to our understanding on the influence of observation on human learning and aggression
- arguments against exposing children to violent media

45
Q

imitation

A

copying behaviour that is unlikely to occur naturally or spontaneously

46
Q

what are the 4 cognitive processes in the modelling of others behaviours

A
  1. attention - models that get attention are likely to be imitated
  2. retention - must remember what the model did
  3. reproduction - must be able to reproduce the behaviour
  4. motivation
