Q

premark principle

A

making the opportunity to engage in a behavior that occurs at a relatively high free operant (or baseline) rate contingent on the occurence of low-frequency behavior will function as reinforcement for the low-frequency behavior

Q

variables affecting reinforcement

A

motivation
- satiation, deprivation
motivating operations
- establishing, abolishing
immediacy
- reinforcer must immediately follow response
- fade over time
set an easily achievable initial criterion for reinforcement
use high quality reinforcers
use varied reinforcers
use direct reinforcers
combine response prompts with reinforcement
reinforce each occurence initially
use contingent attention and descriptive praise
gradually increase response- to reinforcement delay
gradually shift from contrived to naturally occurring reinforcers

20
Q

fixed-interval

A

time based: reinforcement delivered after a specific amount of time
time period is fixed
reinforcer delivered contingent upon the first behavior following the time period
results in a scallop pattern of responding
- more responses as the time period elapses

21
Q

variable-interval

A

time baed
time period is variable
reinforcer delivered contingent upon first behavior following the time period
results in a consistent rate of responding

22
Q

fixed ratio schedule

A

response based
requires completion of a specified number of responses to produce a reinforcer
results in rapid rates of responding

23
Q

variable-ratio

A

response based
requires a completion of a variable number of responses
results in rapid rates of responding

24
Q

Complex schedules

A 
progressive
concurrent 
multiple
mixed
tandem
25
Q

preference assessments

A

formal: ahead of time prior to teaching
informal: not done ahead of time. done in context of teaching
important for those who cannot indicate what they want

26
Q

Graff and Krasten

A

surveyed 402 professionals
32% were BCBA or BCaBAs
89% used in the course of intervention

27
Q

Informal Interviews

A

interviewing the student, teacher, caregiver
face-face or filling our an assessment
- reinforcer assessment
-school reinforcement survey schedule
generates a list of potential reinforcers
provides choice
shown to be unreliable

28
Q

Free Operant preference assessment

A

free access to a variety of stimuli for a duration of time
no stimuli are removed
record duration or interaction/engagement
provides a hierarchy/rank of preferences
shorter than formal preference assessments
results in lower levels of aberrant behavior

29
Q

Free operant video

A

told em to go play and you sit back and relax

watched what he played with and you can determine some potential items that are used as enforcers

30
Q

multiple stimulus without replacement (MSWO)

A

present a number of stimuli to the student
pre-exposure to stimuli

have them play with the stimuli and you can teach them how to

components:
1. arrange full array of stimuli
2. instruct student to select one
3. student interacts for period of time (time reasonable for activity)
4. stimulus is removed
5. repeat steps 1-4
provides a hierarchy
- shows most preferred item to least preferred they would like to play with

31
Q

Multiple stimulus with replacement

A

similar to above, but,

32
Q

paired stimulus preference assessment

A 
a choice between two stimuli 
pre-exposure to stimuli 
components:
1. present two stimuli
2. instruct student to select one
3. student interacts for period of time
4. repeat steps 1-3 until all stimuli paired
Best to conduct multiple assessments
Randomize placement
creates a hierarchy 
typically longer then msw(o)
can result in problem behavior because they do not want to give up the item
33
Q

In the moment reinforcer analysis

A

no formal preference assessment done ahead of time
in the moment assessing what can be a potential reinforcer in the moment and evironment
- verbal and non-verbal behavior
- frequency of delivery
- ability to conidtions
look at data to see what stimuli to use

34
Q

clinical judgement

A

interfering behaviors: some items may interfere
verbal behavior: are they saying they want it
non verbal: are they smiling or frowning? body language?
receptive: hesistant or take ti eight away?
playing style: do they know how to play with it? are they having fun?
age appropriate: item age apps. to the learner
recent performance and past: is behavior changing? if not then we don’t have a functional reinforcer
health benefits: is it unhealthy physically? too much sugar and calories
socialization: can you use it as a single person or part of a game
novelty
conditioning
overall number: how many times did you give them the reinforcer? deprivation or satiation?
location: can be used in specific areas?

35
Q

Conditioning Reinforcers

A

food is often used, that not healthy man

36
Q

Age inappropriate reinforcers

A 
things like barney and the wiggles
problem because:
self fulfilling prophecy
not expanding on limited interests- with autism there is often only selected interests and you need to have them increase their interests so they can socialize 
Bullying
37
Q

Conditioning reinforcers

A

taking a non preferred stimulus and make them preferred as a reinforcer
does not require systematic intervention:
money, wine, baseball
individuals with asd does require systematic intervention: must condition the reinforcers

38
Q

methods to condition reinforcers

A

pairing: neutral (un preferred) stimulus and pair with an established reinforcer
observational learning: watching others access stimuli

39
Q

10 commands of reinforcement

A
  1. must use it: tangible items and social praise
  2. preferences do not equal reinforcers: it’s a functional reinforcer if behavior increases as you present it
  3. must be made contingent: on that target behavior
  4. reinforcement does not equal food
  5. reinforcement may have to be conditioned: overtime
  6. The concept of reinforcement might have to be taught
  7. reinforcement is for skill acquisition and more importantly for reduction of aberrant behavior
  8. Reinforcement needs to be thinned: thinning schedule- looks like a vending machine
  9. Reinforcement does not equal bribery: bribery- promised reinforcement if behavior stops. reinforcement- student uses appropriate behavior and receives reinforcement
    problems with bribery: usually works, reinforces disruptive behavior, it facilitates negotiation, it reduces independence
  10. Must be age appropriate reinforcers
40
Q

Reinforcement Peeves

A
  • Free access: must be sure the children are not getting items freely but that it is contingent upon their behavior
  • used to entice: not bribery but bribery land.
  • Reinforcement schedule not thinned
  • not having it ready
  • comments don’t match performance/ behavior (your verbal behavior must match their performance)
  • not rotating out (want a lot of toys, items, tangibles)
  • not creating (make neutral items preferred)
  • formal preference assessments
41
Q

Token economies

A

commonly implemented
student earns tokens contingent upon target behavior
tokens are then exchanged for terminal reinforcer in the end
examples:
diminishing field, competitive token economy, level system

42
Q

tokens

A

not weird but natural as possible

can take many forms

43
Q

terminal reinforcers

A

vary

could be differential

44
Q

delivering tokens

A

higher quality= more tokens

45
Q

exchange rates

A

depends upon the rate of behavior

46
Q

token economies: traditional approach

A 
determine target behavior(s)
determine criterion for token delivery 
determine exchange rate 
ensure quality "time-in" 
must be trained
start with fewer tokens
move to more tokens
make sure the student is aware they are getting/losing tokens 
should be able to cash in
47
Q

Rainbow tokens

A
  • A conjugate schedule of reinforcement (continuous)
  • tokens movements towards the board is contingent upon target behavior
  • tokens movement stops or restarts contingent upon other behavior
48
Q

Magic number system

A

learner is getting tokens throughout session. learner cashes in for preferred items
