Q

how does positive reinforcement differ from negative reinforcement

A

positive: occurrence of behaviour is followed by the ADDITION of a stimulus (or event)

negative: occurrence of behaviour is followed by the REMOVAL (or AVOIDANCE) of an aversive stimulus

Q

what is a fixed ratio schedule? what are some effects of it

A

Q

Q

what is a fixed interval schedule of reinforcement? effects?

A

reinforcer for FIRST RESPONSE after a given amount of time

  • produces low rates of responding, with on-off pattern
  • response rates increase near end of interval

eg. every 30 minutes Pablo’s supervisor comes around and gives him a token for the first part Pablo packages

Q

Q

a _____ reinforcer became established as a reinforcer by being paired with another reinforcer

A

conditioned

22
Q

all of the schedules of reinforcement that are in effect for a person’s behaviours at one time are called

A

concurrent schedules of reinforcement

23
Q

a number of different behaviours or response options are concurrently available for a person. these response options are called

A

concurrent operants

24
Q

identify the following schedules of reinforcement (CRF, FR, VR, FI, VI)

  1. the reinforcer is delivered for the first response after x amount of time
  2. the reinforcer is delivered after every response
  3. the reinforcer is delivered after an average of x response
A
  1. fixed interval
  2. crf - continuous
  3. vr - variable ratio
25
a consequence that strengthens operant behaviour is a(n) ______________
reinforcer
26
when Todd gets bitten by bugs, he puts medication on the bites that relieves the itching. as a result, he is more likely to put medication on his bug bites. this is an example of _____________ reinforcement
negative
27
when Frida punches her brother, she gets scolded by her parents. as a result she is more likely to punch her brother this is an example of ____________ reinforcement
positive (attention)
28
the stimulus that is removed after the behaviour in negative reinforcement is called a(n) ____________ stimulus
aversive
29
identify the following schedules of reinforcement (CRF, FR, VR, FI, VI) 1. a reinforcer is delivered after x responses 2. a reinforcer is delivered for the first response after an average of x amount of time
1. fixed ratio 2. variable interval
30
what is the schedule of reinforcement in which the reinforcer is Not delivered after every response? what if it is?
intermittent reinforcement schedule continuous (crf)
31
deprivation makes a reinforcer _______ potent
more
32
satiation makes a reinforcer _______ potent
less
33
in what way are positive and negative reinforcement alike?
both occur after a behaviour. both increase/strengthen the behaviour
34
a type of positive reinforcement where a high-probability (preferred) behaviour is a consequence for performing a low-probability behaviour -> increasing the low-probability behaviour
Premack principle eg. do homework before play video games
35
Shae checks her email periodically. email messages come at unpredictable intervals. shae's behaviour of checking her email is reinforced on what schedule?
intermittent reinforcement schedule
36
Bob is a telemarketer and makes phone calls in an attempt to sell product. He never knows when someone will agree to buy but must make anavg of 13 calls to achieve a sale. his behaviour of making calls is reinforced on what schedule?
variable ratio
37
what is an operant behaviour?
a behaviour that is strengthened through the process of reinforcement
38
define positive reinforcement (and negative)
the occurrence of a behaviour is followed by the addition of a positive reinforce and the behaviour is more likely to occur in the future same thing but the behaviour is followed by the removal (or avoidance) of an aversive stimulus
39
what is an aversive stimulus?
smth unpleasant, painful or annoying that a person wants to get away from eg. kid yelling annoying to the parent
40
what is meant by contiguity between a response and a reinforcer?
how immediate a consequence/reinforcer is given longer delay between response and consequence = less effective
41
what is a reinforcement contingency?
consistency a behaviour is strengthened when a reinforcer is contingent on the behaviour (when it only occurs if the behaviour occurs)
42
what is an establishing operation (EO) examples?
a motivating operation (MO) that makes a reinforcer more potent (it establishes the effectiveness of a reinforcer) - deprivation - not eating for a while is an EO that makes food MORE reinforcing at that time and makes the behaviour of getting food MORE likely to occur
43
what are two effects of MOs?
1. they alter the value of a reinforcer 2. they make the behaviour that produces that reinforcer more/less likely to occur at that time
44
what's an abolishing operation? (AO) examples?
a motivating operation (MO) that makes a reinforcer LESS potent (it abolishes or decreases the effectiveness of a reinforcer) - satiation - having just eaten a large meal is an AO that makes food LESS reinforcing at that time and makes the bhvr of getting food LESS likely to occur
45
what are two effects of an EO? AO?
EO: 1. makes a reinforcer MORE potent 2. makes a behaviour that produces the reinforcer MORE likely AO: 1. less 2. less
46
a CRF schedule is used for acquisition and an intermittent schedule is used for maintenance. describe what this means
crf for aquisition: - used when a person is learning a behaviour intermittent for maintenance: - used for an acquired behaviour to ensure they keep doing it
47
are interval or ratio schedules more likely to be used in teaching or training programs?
FI rarely used in training programs because responses drop after the reinforcement is given FR or VR are more commonly used because they produce higher and steadier rates of responding
48
what are concurrent schedules of reinforcement
all the schedules of reinforcement that are in effect for a person's behaviours at one time
49
what 4 factors influence which response option a person will choose at any point in time
1. schedule of reinforcement 2. magnitude of reinforcement 3. immediacy of reinforcement 4. response effort
50
what is the matching law
a mathematical model of choice in concurrent operants that predicts that a response that produces a greater rate of reinforcement will occur more often than a response that produces a lower rate
51
what is a multiple schedule of reinforcement? example?
an example of a combined schedule of reinforcement two basic schedules occur sequentially and each is associated with a different SD eg. "question time" vs "quiet time" in classroom question time: teacher provides help when students ask - crf quiet time: teacher no longer provides help when they ask - extinction is in effect
52
what is behavioural contrast?
something that may occur when a multiple schedule of reinforcement exists change in reinforcement schedule changes not only the rate of responding in that component but also changes the rate of responding in the opposite direction in the other component eg: Class A started using extinction for a problem behaviour but class B did not. behaviour is likely to decrease in A but also increases in B (even though the schedule of reinforcement did not change in B)
