Q

what is the shaping guidelines

A
  1. Define target behavior
  2. Determine whether shaping is the most appropriate procedures: shaping might not be the best producers if the behavior is put of the individual natural behavior
  3. Identity the starting behavior
  4. Choosing the shaping steps
  5. Choose the reinforcer
  6. Differentially reinforces successive approximations. only reinforce in the forward direction, do not reinforcer previous successful behavior
  7. Move through the shaping steps at a proper pace

Q

what are tips for shaping

A
  • reinforces in small steps
  • uses continuous reinforcement
  • provide immediate reinforcement , don’t wait to see if they will do more
  • provide small or conditioned reinforcers to prevent satiation
  • skip ahead when possible, so if later behavior occurs and reinforce it
  • back up when necessary, when there hasn’t been a behavior to reinforce
  • following successful shaping,move to intermittent schedules or reinforcement to avoid extinction

Q

what can be used to mark behavior

A

After completing the behavior quickly provide the reinforcement to determine the desired behavior. A clicker can be used to immediately conditionally reinforce consequences if provided and this prevents accidental reinforcement of other behavior

Q

what is response prompt

A

the behavior of another person evokes the desired response in the presence of the discriminative stimulus. (discriminative stimulus is the antecedent stimuli that has stimulus control over the behavior becasue the behavior has been reliably reinforced in the presence of the stimulus)

Q

what is fading

A

transferring the discriminative control of one stimulus (s1) to another itmulu (s2) by gradually eliminating s1 in the presence of s2
it is shifting the discriminative control of one stimulus to another stimulus
ex: train birds to hop in the feeder if the light is red, then pair the light and tone before they hop in the feeder. shifting what prompt their behavior

Q

what is behavior chain

A

most behavior are actually complex combinations of simpler behavior in a particular order
A complex behaviour consisting of two or more
component behaviours that occur together in a
sequence

Q

what is total task presentation

A

is using prompting to get the learner to perform the whole chain from start to finish, using prompting
using graduated guidance
ex: if a toddler is learning to wash their hand, the parents can physically take them through the process of washing their hands. Then eventually you can use gesture prompting and eventually less invasive prompting
what we need to consider with this method is
- task complexity
- leaner ability
-teacher ability

Q

what are remedies of the long-term consideration

A
  • Use a stronger terminal reinforcer
  • Shorten the chain
  • Highlight natural rewards the chain provides (if any)
  • Intermittently reinforce smaller sections of the chain
36
Q

what is the functional assessment process

A
  1. identity and define a target behavior that needs to be increased or decreased
  2. Initiate baseline data collection
  3. complete functional assessment by hypothesizing about antecedent and consequences
  4. develop and implement treatment
  5. evaluate the effectiveness of treatment and its implementation. was the treatment effective
    if the treatment was effective begin to promote maintenance and generalization (reinforced intermittently and apply strategies to foster generalization)
    if the treatment was not effective check for treatment fidelity. if the treatment was implemented correctly . if it was not implemented correctly retrain staff, adjust components and/or procedures
    if it was implemented correctly, return to step 3
37
Q

what is antecedent (stimulus)

A

it is when, where, with whom and in what circumstances or situation does the behavior occur
ex: contextual stimuli, preceding behaviors and circumstances, time of day)

38
Q

what is behavior

A

-problem behaviors
- alternative behaviors
-relevant variable (ex: intensity, latency, topography etc)

39
Q

what is consequences

A

for both problem and alternative behavior, you have to assess the social and environmental (automatic) consequences. so you can consider the schedule of reinforcement, magnitude of reinforcement, immediacy of reinforcement

40
Q

what i the categories of reinforcement (functions of problem behavior)

A
  • social positive reinforcement
  • social negative reinforcement
  • automatic positive reinforcement
    -automatic negative reinforcement
41
Q

what is social positive reinforcement

A
  • it is mediated by others
    -attentions, praise, reactions, activites, things
42
Q

what is social negative reinforcement

A
  • also mediated by others
  • it is escape from aversive task (outbursts result in termination of school work), interaction (anger displays get a partner to stop arguing), physical stimulation (a parent’s nagging gets a teenager to turn down the stereo)
43
Q

what is automatic negative reinforcement

A

This reinforcement is a natural consequence of a behavior meaning it is not mediated by others
it can be relief from anxiety, fear, aversive stimulation , and aversie environmental stimuli

44
Q

what is automatic positive reinforcement

A

when you do something that results in the desired outcome of something good being added.
sensory stimulus, environmental stimuli and events

45
Q

what are the type of assessment

A
  1. indirect (informant) assessment
  2. direct observation assessment
  3. functional /experimental analysis
46
Q

what is indirect (informant) assessment

A
  • behavioural interview
  • rating scales and questionnaire
  • low reliability, biased, inaccurate and incomplete
  • instead it is useful as a starting point
47
Q

what is direct observation assessment

A
  • descriptive A-B-C recording
  • checklist recording of A-B-C
  • interval recording of A-B-C
    -we need to consider reactivity, practical and ethical feasibility, recruiting informants
48
Q

what is functional/experimental analysis

A

this is not a treatment, it is a type of assessment
- manipulate variables to demonstrate a functional relationship
replication is key
manipulate antecedents and consequences
observes changes in behavior and replicate

49
Q

what are the two types of functional analysis

A
  1. hypothesis testing: test hypothesis from descriptive assessment
    2.exploratory: test a range of possible function
50
Q

what are the functional assessment condition

A

test condition: present EO and deliver reinforcer for problem behavior
control condition: present AO and do not deliver reinforcer for problem behavior

51
Q

Test and control conditions by function:

A
  • attention
  • tangible
  • escape
  • automatic reinforcement
52
Q

what is an exploratory FA

A
  • Separation in the data (elevated data) in one test condition – indicates function
  • Data elevated in all test conditions – indicates multiple functions or automatic reinforcement
  • Extended alone conditions – elevated data indicates
    automatic reinforcement
53
Q

what is hypothesis testing

A

Separation in the data between the test and control
conditions

54
Q

what is extinction

A

it is the procedures of withholding reinforcers that maintain a behavior

55
Q

what is functional treatment to extinction

A

it is based on functional assessment information. alter antecedents and/or consequence in the functional assessment

56
Q

what is nonaversive treatment

A

do not involves punishment procedures

57
Q

what are similarities between functional and non aversive treatment

A

extinction, differential reinforcement and antecedent manipulation work together
These treatments are the first choice for treating an undesirable behavior. however most restrictive treatment are used if functional and averise treatment doesn’t work

58
Q

what are some important considerations to functional and aversive treatment

A
  1. have you identified the reinforcer
  2. is it even possible to eliminate reinforcer
  3. is it safe to use extinction (emotional response, extinction burst, behavioural variability)
  4. can you apply extinction consistently
  5. do you have a method to promote generalization and maintenance
59
Q

what reinforcement is vulnerable to extinction

A

continuous reinforcement

60
Q

what reinforcement is resistant to extinction

A

intermittent reinforcement

61
Q

what is generalization

A

conduct extinction in all environment that the problem behavior may occur

62
Q

what is maintenance

A

conduct extinction any times the problem behavior occur

63
Q

what is differential reinforcement

A

it is operant training procedures in which some behavior is systematically reinforce and others are not. it is extinction and reinforcement together

64
Q

what are differential reinforcement

A
  1. differential reinforcement of low rates (DRL)
  2. differential reinforcement of high rates (DRH)
  3. differential reinforcement of other behavior (DRO)
  4. differential reinforcement of alternative behavior (DRA)
65
Q

what is differential reinforcement of low rates

A

behavior is reinforced if you don’t exceed this certain response under this amount of time in a given period. So we should see a decrease in the number of response

ex: reinforce pigeon peck only after 5 sec since the last peck, nothing less than five second

This might produce superstition behavior because it can encourage doing a certain action to be reinforced. for example a pigeon might think they need to spin around to be reinforced when it is actually them pecking. This meant to reduce rates of behavior

66
Q

how to use DRL

A
  1. . Determine if DRL is appropriate procedure.
    * i.e., decrease behaviour, but not eliminate it!
  2. Determine an acceptable level of the behaviour.
  3. Decide to implement full-session or spacedresponding DRL.
  4. Inform the client about the procedure & criterion
    for reinforcement.
  5. Provide feedback on performance
67
Q

what is differential reinforcement of high rates

A

behavior is reinforced if you respond for AT LEAST a certain number of response
ex: if a pigeon has pecked at least 5 times within 10 second
This is useful when the goal in increasing a behavior

68
Q

what is differential reinforcement of other behavior

A

reinforced is given if the a certain behavior doesn’t not happen for a period time
ex: if a pigeon doesn’t peck after 10 sec reinforcement is given
This is meant to eliminate the rates of behavior, it is useful when extinction is not an option and reinforcers are intrinsic to the behavior

69
Q

how to use differential reinforcement of other behavior

A
  1. define a target behavior to increase and decrease
  2. choose a reinforcer for DRO
  3. Choose the initial DRO interval (how long they shouldn’t perform the behavior before they reviewed the reinforcement
  4. eliminate the reinforcer for the problem behavior and deliver the reinforcer for the absence of the problem behavior
  5. reset the interval if the problem behavior occur
  6. gradually increase the interval length
70
Q

what is the whole interval DRO

A

The problem must be absent for the whole interval for reinforcement. This is simply DRO
this is basically DRO

71
Q

what is momentary DRO

A

The problem must be absent at the end of the interval for reinforcement

72
Q

what is differential reinforcement of alternative behavior (DRA)

A

a replacement behavior is reinforced while an undesired behavior is extinguished
ex: if a child is colouring on the wall, the parents encourage the kids to colour on paper
Using DRA is easier if the desirable behavior occurs occasionally or can be prompted similarly to shaping
It can promote creativity as you can differentially reinforced response that have not recently been used

73
Q

how to use DRA

A
  1. define the target behavior to increase and decrease
  2. identity the reinforcer for the problem behavior
  3. choose a reinforcer for the desirable behavior
  4. reinforce desirable behavior immediately and consistently
  5. extinguish or devalue the reinforcer for the undesirable behavior
  6. begin to incorporate intermittent schedules of reinforcement for the desirable behavior
74
Q

how to identify putative reinforcer

A
  1. use reinforcers maintaining undesirable behavior
  2. observe activities that are enjoyable and occur with high probability
  3. ask question
  4. conduct preference assessment : we have single stimulus preference assessment, paired stimulus preference assessment, multiple stimulus preference assessment
75
Q

how to choose reinforcer

A
  1. observe
  2. ask
  3. test using single stimulus preference assessment, paired stimulus preference assessment, multiple stimulus preference
76
Q

what is single stimulus preference assessment

A

potential reinforcers presented individually multiple times in random orderings because we want to ensure there is no environmental factor that contributes to the appealing of the reinforcer
then the percentage of approaches are calculated

77
Q

what is multiple stimulus

A
  • potential reinforcers are presented in a full array to randomize the order of the reinforcer
  • items are removed as they are chosen
  • process is repeated with varied item ordering
  • items chosen first are likely more reinforcing
77
Q

what is paired stimulus assessment

A

potential reinforcer in pairs
- each stimulus is presented with every other stimulus multiple times
- then the percentage of approaches/selection are calculated

78
Q

what is differential negative reinforcement of alternative behavior

A

students are negatively reinforced (a perceived aversive stimulus is removed) for engaging in the desired academic task at certain levels of proficiency.

79
Q

what are Differential reinforcement of incompatible behavior (DRI):

A

variation of DRA. behavior that is incompatible with the unwanted behavior is reinforced
Increasing rate of desired behaviour also decreases the
rate of undesired behaviour because the two cannot
occur simultaneously
ex: instead of biting their nails, then do something that requires using your hand and you reward yourself you were doing something else instead of biting your nails

80
Q

what are Differential Reinforcement of Communication (DRC)

A

aka functional communication training: a communication response is reinforced to replace the problematic behavior. An individual can ask for their reinforcer

81
Q

what is controlling stimulus (S)

A

any antecedent stimulus or event that changes the probability of an operant behavior
there are three types which are Sd, SΔ, Save

82
Q

what is discriminative stimulus

A

a stimulus or event that precedes an operant and sets the occasion for its reinforcement

83
Q

what is extinction stimulus

A

a stimulus or events that precedes an operant and sets the occasion for its non-reinforcement

84
Q

what is antecedent control procedures

A

manipulating controlling stimulus to make desirable more likely and make undesirable less likely

85
Q

what is the procedures for increasing desirable behavior

A
  1. present discriminative stimulus for a desired behavior
  2. develop new discriminative stimulus by limiting the occurrence of specific behavior to specific situation
  3. arrange establishing operation for desirable behavior
  4. decrease response effort for desirable behavior
86
Q

what is the procedures for decreasing undesirable behavior

A
  1. remove the discriminative stimulus for undesirable behavior
    2 make the behavior impossible
  2. present abolishing operation for undesirable behavior
  3. increase response effort and/or delay for undesirable behaviors
  4. extinguish discriminative stimulus for undesirable behaviour when they can’ be easily avoided
