Q

assessment

A
  • a SYSTEMATIC method for obtaining info abt the FUNCTION challenging Bx serve for an individual
  • allow us to make EMPIRICAL-based HYPOTHESES for WHY Bx occur
  • a variety of method to identify targets for B change: direct observations, interviews, checklists, tests
  • discovers: resources, assets, sig. others, competing contingencies, maintenance & generalization factors, potential R/P

the shape of assessment is funnel 漏斗: with a broad scope that narrows focus as you conduct the assessment process

Q

pre-assessment considerations

A
  • *ethics**
  • BEFORE conduct an assessment, must ask criteria question: who has the authority, permission, resources, skills to complete an assessment & intervene with the B
    e. g. a BA do NOT have the authority to intervene in a kid on the street!!
  • BEFORE implementing assessment: should obtain the client’s or client surrogate’s WRITTEN approval of the assessment procedure

Q

indirect assessment measures

A
  • data obtained from recollections, reconstructions, SUBJECTIVE ratings of events
    • interviews
    • checklists
  • NOT as reliable as direct assessment
  • should ONLY be used as SUPPLEMENT to other FBA methods
  • start the hypotheses development process

Q
  1. behavioral checklist
A
  • likert scales
  • alone / with interviews & rating scales
  • ask abt ANTECEDENTS & CONSEQUENCES of the target Bx
  • published checklist:
    *CBCL: child behavior checklist: teacher, parent, child report forms (age 5-18) [Achenbach & Edelbrock, 1991]
    • ABS-S: adaptive behavior scale-school: assess children’s adaptive behavior [Lambert, Nihira, Leland 1993]
    • ABS-RC: ABS-residential & community
      [Lambert, Nihira, Leland 1993]

Q
  1. observations
A
  • direct & repeated in the NATURAL environment
  • identify potential target Bx
  • PREFERRED method
  • ANECDOTAL observation / ABC recording: basic form of direct observation
  • temporally sequenced description of B patterns
  • requires TOTAL attention of observer for at least 20-30 mins CONTINUOUSLY
  • NOT good option for class teacher coz they have other things to do & can’t commit full attention to data
  • do NOT write interpretations, only what is observable & measurable
  • carry out for several days to decrease REACTIVE EFFECTS

Q
  1. interviews

structured behavioral interviews

A
  • 1st step to identifying list of Bx that can be used later in direct observation

2 sources of interviews

a. the individual:
- ask what, when etc. questions but NOT why
- identify PRIMARY concerns of the INDIVIDUAL
- can give the individual questionnaires / have them record self-monitoring data
b. significant others:
- e.g parents, etc
- good way to assess the individual’s sig. others in your INTERVENTION plan

Q
  1. tests

standard test

A
  • published standardized tests, e.g. ABLLS
  • CONSISTENT administration: same questions & tasks are presented in a specified way & same scoring criteria & procedure are used EACH time
  • most standardized test do NOT work well with FBA coz results are NOT directly translated into target Bx
    e. g. a standardized test shows a 4th grader performs at 3rd grade level. it can NOT tell what academic skills he mastered / what he needs help
  • LICENSIGN requirement: only a licensed psychologist can administrate some intelligence tests

Q

consider biological / medical variables may affect the client

A

ethics: RULE OUT medical causes for problem Bx–> should recommend seeking medical consultation if there’s a reasonable possibility the B results from a medication side effect / biological cause

  • refer client to undergo medical evaluation
  • if bio/medical variables are affecting the B, there may be NO need for behavior analytic services
  • if NO bio/medical effects, there MAY be a need for behavior analytics

Q

preliminary assessment to identify referral problem

A
  • if NO identified medical/bio causes & there’s a need for intervention: conduct an INDIRECT assessment to start the identification & hypothesis process
  • gather info indirectly: interview, rating scales, screening forms, etc
  • during a preliminary assessment, ask: if there’s a need for intervention:
    • does the person’s B pose a DANDER to self/others?
    • does the B affect one’s WELL-BEING?
    • does the B prevent the person from accessing LESS RESTRICTIVE environments: separated from same-aged peers, in danger of losing placement?
    • how does the B compare to same-aged typically developing peers?

explain behavioral concepts in NON-TECHNICAL language

A
  • *ethics**
  • use language that is FULLY understandable to the recipient of the service
  • avoid using complicated technical behavioral analytical language
  • do NOT use mentalistic language (e.g. think, feel)

Q

describe & explain B (private & public events) in behavioral analytic terms

NON-mentalism (hypothetical & unobserved)

A
  • do NOT discuss problems in mentalism terms –> coz this does NOT offer a solution
    e. g. he is aggressive coz he has ASD.

Q

select intervention strategies based on environmental & resources constrains

A
  • *ethics**
  • BA gets to know the physical, materials, human resources in the family/organization where the B changes are to occur
  • learn the values & concerns of key stakeholders
  • look to see what adjustments might be required in the system to monitor, encourage & sustain/maintain the kinds of changes
  • if resources are NOT available, must adjust our goals/methods

Q

identify & make environmental changes that reduce the need for behavior analysis services

A
  • *ethics**
  • environment/ecology: physical settings + ppl in the environment
  • change ecology / how others engage with the client –> B changes
  • identify during INDIRECT FBA: environmental variables that may trigger or reinforce the B
  • seek to ELIMINATE the environmental constraints or identify the obstacles in WRITING, if they hamper implementation of the B analytic program

ecological assessment

physical environment + ppl

A
  • a great deal of info abt the individual & settings where one lives & works
  • physiological conditions, physical settings, interactions with others, home environment, etc
  • creates DESCRIPTIVE data
  • costly in times & money etc
  • should know when it’s appropriate to use

Q

reactivity

A
  • the effects of the assessment process on the B being assessed
  • reactivity most likely when observations are OBTRUSIVE/obvious to the individual
  • self-monitor: most obtrusive data collection method
  • reactive effects are usually temporary
  • reduce reactivity:
    • as unobtrusive/unobviously as possible
    • repeat observations until reactive effects subside/decrease
    • take reactivity effects into account when interpreting data

Q

assess social sig. of potential target Bx

A

“ethics”

  • consider WHOES B is being assessed and why
  • ask: to what extent the proposed change improve the person’s life
  • NOT ok to change B for benefits of others, e.g. be still, be quiet
  • NOT ok to change B coz you want to, e.g. teach cursive 草书 to one who can’t read

Q

habilitation

adjustment

A
  • assess the meaningfulness of change
  • is the change really useful to the CLIENT?
  • habilitation occurs when a person’s repertoire has been changed such that short & long term Rs are max., short & long term Ps are min.
  • assess if the target Bx you might change in a client will be habilitative for the client

Q

10 questions to ask when evaluating habilitation/social sig. of target Bx

A
  1. relevance of B rule: is the B likely to produce R in the client’s NATURAL environment after intervention ENDS?
  2. is the B a prerequisite for a more complex functional skill?
  3. will the B increase the client’s access to environments?
    • access Bx: producing indirect benefits to clients
      e. g. teach SENs to stay in seat, interact politely with others–> expect to increase acceptance in general education classroom
  4. will change this B predispose/influence others to interact with the client in a more supportive manner?
  5. is the B a pivotal B (access to untrained Bx) or a behavioral cusp (access to new environment/Rs)?
  6. is it an age-appropriate B?
  7. if the B is to be reduced/eliminated from one’s repertoire, has an adaptive & FUNCTIONAL B been selected to replace it?
    • constructional approach: to build/construct replacement Bx when a target B is removed
    • eliminative approach: gets rid of target Bx without construct anything in replacement
  8. does the B represent the actual goal or only indirectly related?
    e. g. increase on-task B –> increase work output (actual goal)
  9. is it just talk or the real B of interest? BA actually changes Bx
  10. if the goal is not a specific B, will this B help to achieve it?
    • sometimes target changes are NOT B, but the result of the PRODUCT of certain Bx
    • target on most directly & functionally related behaviors
      e. g. losing weight is NOT B, but reduced food consumption, increase exercise are Bx.
      e. g. earning good grade is NOT B, but studying is B

normalization

mainstreaming

A
  • the belief/goal that ppl with disabilities should be physically & socially integrated into MAINSTREAM society regardless of the degree/type of disability to the MAX extent possible
  • use progressively more typical settings & procedures to establish personal B that are as CULTURALLY NORMAL as possible

Q

behavior cusp

Rosales-Ruiz & Baer

A
  • B that has consequences beyond the change itself
  • expose the person’s repertoire to new environments: new Rs/Ps, new contingencies, new responses, new stimulus controls, new communities of maintaining / destructive contingencies –> one’s repertoire expands
  • cusps NOT same as prerequisite/component Bx
    e.g. crawling is a cusp: enable to access new environment/Rs/contingencies
    component Bx of crawling: specific arms, head, legs movements
  • select B cusps as goals for intervention to make learning more EFFICIENT
    e. g. reading, general imitation

Q

pivotal Bx

Koegel & Koegel, US Santa Barbara

A
  • a B once learned that produces corresponding modifications or covariations in OTHER adaptive UNTRAINED Bx
  • once learned a pivotal B–> lead to more complex Bx
    e. g. teach ASD child to self-initiate (i.e. approach others): pivotal for the emergence of UNTRAINED Bx/response classes: asking questions, increased production & diversity of talking
    e. g. joint attention
  • teach pivotal Bx reduces intervention times
  • pivotal response training (PRT): focus on more comprehensive pivotal areas: increase one’s motivation to learn, initiate communication, monitor one’s own Bx.
    PRT emphasis/focuses on motivation

Q

B cusps vs. pivotal Bx

A

similarities

  • both are Bx BA wants to teach 1st to clients –> upon which other Bx can be built
  • select B cusps & pivotal Bx when creating intervention goals

differences

  • B cusps are more abt accessing new environments & contingencies
  • pivotal Bx are more abt experiencing changes in UNTRAINED Bx

Q

prioritize target Bx

A
  • *ethics**
    1. threat to the health/safety of client or others
    2. frequency
    • opportunities to use/maintain new Bx in the natural environment
    • occurrence of problem
      1. longevity of problem: chronic problem comes before new one
      2. potential for HIGHER are of R
      3. relative importance of the target B to FUTURE skill development & independent functioning
      4. reduction of NEGATIVE ATTENTION from others
        e. g. idiosyncratic public displays / mannerisms
      5. R for sig. others
      6. likelihood of success: some Bx are harder to change
      7. cost-benefit ratio: include time & effort. low-cost & high benefit

Developing & using a target behavior ranking matrix
- 0 - 4: no value - maximum value
- Weight some of the variables differentially
E.g. senior citizen: immediate benefit
Secondary students: relevance to future skill development & independent functioning
- Conflicting goals: obtain client, parent, practitioners in the goal determination process

Q

FBA methods pyramid

A

top to bottom:

analog assessment/ functional analysis –> descriptive diret assessment –> indirect assessment

36
Q

analog assessment/

functional analysis

A
  • the ONLY FBA method that allows us to confirm HYPOTHESES regarding FUNCTIONAL RELATIONS between Bx & environmental events
  • arrange/manipulate ANTECEDENTS & CONSEQUENCES to observe their SEPARATE effects on Bx
  • gold standard of assessment procedure
  • analog: arrange variables NOT settings where assessment occurs
  • analog conditions allow better control of variables
  • functional analyses done in natural settings yield same results as in simulated settings

2 types of functional analyses

  1. extended functional analysis
  2. brief functional analysis: a brief version of extended functional analysis
37
Q

4 typical original conditions of functional analysis

A

3 test conditions & 1 control condition:

  1. contingent ATTENTION: social disapproval condition
  2. contingent ESCAPE: academic demand condition
  3. alone (automatic R/sensory)
  4. control: play condition. problem Bx is low in this unstructured condition coz R is freely available & no demands
  • each test contains an MO & a potential source of R for B
  • conditions are presented SYSTEMATICALLY, 1 at a time & in alternating sequence until a PATTERN of problem B emerges
  • sessions are repeated
  • based on Iwata’s research on FA
  • 5th condition: tangible: ONLY used when suspect the client’s problem B’s function is to attain access to a tangible
38
Q

interpret FA data

A

visually inspecting a graph of the result to see the conditions under which HIGH rates of B occurs

39
Q

interpret FA data: attention

A
  • contingent attention condition = +ve R
  • this conditon test for +ve R
  • *how**
  • give attention –> then remove attention to establish the MO (deprivation of attention)
  • if problem B occurs, give a mild reprimand (“No”) & remove attention again
  • each time problem B occurs, give a reprimand & remove attention again
  • if the rate of problem B is HIGH in this condition, attention is the maintaining R
40
Q

interpret FA data: escape

A
  • contingent escape condition = -ve R
  • this condition is test for -ve R
  • *how**
  • give NON-preferred demands repeatedly to establish the MO (satiation for the aversive task)
  • if no response/incorrect response, then prompt a correct response
  • if problem B occurs, remove the demands. (“ok, we don’t have to do this right now”). the demands are then reintroduced
  • each time problem B occurs, remove the demands & reintroduce them again after some time passed
    • if the rate of problem B is HIGH in this condition, escape is the maintaining R
41
Q

interpret FA data: automatic R (sensory)

A
  • alone condition = automatic R
  • test for automatic R
  • *how**
  • client remains in a room with NO demand / social interaction
  • NO consequence for problem Bx
42
Q

interpret FA data: undifferentiated pattern

A
  • spider web graph
  • means problem B occurs/variable across ALL conditions (include play condition)
  • -> inconclusive results / problem B is maintained by AUTOMATIC R
43
Q

play condition / control condition

A
  • test for automatic R & serve as a control condition
  • *how**
  • leisure materials are FREELY available & attention is given on average every 30 secs (‘i like how you are playing’)
  • NO consequence except WITHHOLD attention until problem B ceased if it occurs at the 30 secs mark when attention was to be delivered
  • if problem B occurs in the presence of PREFERRED items, in the absence of demands, with intermittent attention, then automatic R is the maintaining R or another FA is needed
44
Q

tangible condition

A
  • ONLY use when suspects accessing tangible is the function
  • *how**
  • give access to highly preferred items/activities for a set amount of time, then ask the client to give back or remove it to establish MO (deprivation for the items)
  • each time problem B occurs, the tangible item is returned for a set amount of time, then removes again
  • if problem B increases, access to tangible is the function
45
Q

brief FA

A
  • conduct a FA in a short period of time
  • SYSTEMATICALLY manipulating environmental variables to trigger the problem B & R it when it occurs
    • -> to determine which variable is maintain the B
  • 4 variables: attention, escape, alone, play
  • each condition is run for 10 mins
  • each condition except alone, must an MO & SD that signal R is available
  • in each condition, purposely trigger the problem B & R it to observe if it INCREASES:
    • the B increase if that consequence is the function
    • the B will NOT increase or occur again if that consequence is NOT the function
46
Q

advantage of FA

A
  • clear demo of variables that related to problem B
  • standard to which all other forms of FBA are evaluated
  • enable development of effective R-based treatment
47
Q

disadvantage of FA

A
  • *ethics**
  • may temporarily strengthen the problem B
  • may result in the B acquiring new functions
  • acceptability is low
  • difficult to use for serious, low freq Bx
  • if conducted in contrived settings, may NOT identify idiosyncratic variables related to problem B
  • require time, effort, professional expertise
48
Q

direct descriptive FBA
descriptive assessment
direct assessment

A
  • direct observation of problem B in NATURAL conditions
  • NO systematical arrangement
  • record data on the occurrence of B within the natural environment where it occurs & environmental events that surround it
  • direct assessment are approximations of FA
  • involves baseline data collection
49
Q

3 data collection methods for descriptive FBAs

A
  1. ABC continuous recording
  2. ABC narrative recording
  3. scatter plot
50
Q
  1. ABC continuous recording
A

record:

  1. occurrences of target problem Bx
  2. selected environmental events within natural routine during a specified period of time
  • all ABC data should be recorded for a min. of 20 - 30 mins
51
Q

advantage of ABC continuous recording

A
  • use precise measures
  • provide useful CONTEXTUAL info & correlations regarding environmental events & problem Bx –> provide useful info for later functional analyses
  • calculates conditional probabilities
    • proportion of the occurrence of problem B preceded by a specific ANTECEDENT
    • proportion of the occurrence of problem B followed by a specific CONSEQUENCE
    • can be misleading
52
Q

disadvantage of ABC continuous recording

A

often antecedent & consequences do NOT reliably precede & follow problem Bx –> make correlations difficult to detect

53
Q

conditional probabilities

A
  • probability that a target B will occur in a specific circumstance
  • taken from ABC data
  • help to hypothesis the function of B
  • looks at the proportion of occurrence of problem B preceded by a specific antecedent &/ followed by a specific consequence
*formula*
# of Bx preceded by a specific antecedent &/ followed by a specific consequence / total # of Bx
  • the closer the probability is to 1.0, the more convincing the hypothesis is
  • reported in decimal form
  • can be misleading
54
Q
  1. ABC narrative recording
    sequence analysis
    A-B-C descriptive narrative data
A
  • data collected ONLY when B of interest are observed
  • recording is open-ended
  • can calculate conditional probabilities
  • difficult to discriminate which environmental events actually occasion the problem B
55
Q

advantages of ABC narrative recording

A

less time consuming

56
Q

disadvantages of ABC narrative recording

A
  • utility in identifying B function NOT established
  • may yield FALSE POSITIVE coz data are collected ONLY when B occurs
  • SAME antecedent & consequence may present when problem B is absent
  • reliability may be low
  • observers may report ‘inferred states’ rather than events
57
Q

scatter plot

pattern analysis

A
  • record the extent to which a target B occurs more often at particular times than others
  • divide day into BLOCKS OF TIME.
  • for each time period, enter a symbol to indicate whether problem B occurs a lot, sometimes, or not at all
  • analyze for PATTERN to identify TEMPORAL distributions of B & events that occur at that time
58
Q

advantages of scatter plot

A
  • identify time periods when problem B occurs

- can be useful for pinpointing periods of the day when more focused ABC assessment can be conducted

59
Q

disadvantages of scatter plot

A
  • subjective
  • does NOT determine the function of problem B
  • does NOT offer replacement Bx
60
Q

indirect FBA

A
  • identify potential events in the NATURAL setting that correlate with the problem B
  • gather info from OTHERS who know the individual very well
  • rating scales, checklists, structured interviews:
  • motivation assessment scale - MAS
  • motivation analysis rating scale - MARS
  • problem behavior questionnaire - PBQ
  • functional analysis screening tool - FAST
  • questions about behavioral function - QABF
61
Q

advantages of indirect FBA

A
  • contributes to hypothesis development

- simple to use coz do NOT require observations

62
Q

disadvantages of indirect FBA

A
  • informants may NOT be accurate
  • little research supports the reliability of info obtained
  • best used for hypothesis development
63
Q

functional equivalence

A
  • *ethics**
  • intervention must match the FUNCTION of B
  • when decrease a B, must select an ACCEPTABLE ALTERNATIVE B / a functionally equivalent replacement B to be established or increase for the client
  • teach functional skills is 1 of the 6 basic client rights in The Right to Effective Behavioral Treatment (Van Houten et al. 1988)
64
Q

make recommendations based on FBA

A
  • established: client does NOT have the target B in one’s repertoire –> teach the NEW B
  • maintained: client has the target B in repertoire –> maintenance OVER TIME in NATURAL environment
  • increased: target B rate is too low–> increase it to an acceptable level.
    e. g. DRH
  • decreased: target B rate is too high–> decrease it to an acceptable level.
    e. g. DRL, DRD
  • eliminate: e.g. DRO (other Bx)
  • conduct discrepancy analysis to tell if problem B is at problematic levels & determine the behavioral standard for acceptability
65
Q

assessment is ongoing

A
  • *ethics**
  • continue monitoring effectiveness of the intervention over time
  • functions of problem Bx are DYNAMIC & CHANGE over time
  • ONGOING evaluation & assessment is 1 of the 6 basic client rights in The Right to Effective Behavioral Treatment (Van Houten et al. 1988)
66
Q

importance of defining target Bx

A

to researchers:

  • definition is required by REPLICATION
  • replication is required by research

to practitioners

  • accurate evaluation requires an explicit definition of B
  • accurate & believable evaluation of effectiveness
67
Q

3 characteristics of good operational definitions

both B & environment variables

A

OCC

  1. objective: refer only to OBSERVABLE
  2. clear: readable & unambiguous
  3. complete: delineate BOUNDARIES of definition (include & exclude)
68
Q

social validity

A
  • *ethics**
  • ensure assessment & intervention has social validity
  • asks: is a person’s life changed in a +ve & meaningful way?
  • 3 factors
    1. social sig. of the GOAL
    2. social appropriateness of the PROCEDURES
    3. social importance of the EFFECTS: are consumers (client & mediators) satisfied with the results?
69
Q

select interventions based on social validity

A
  • determine if the MEDIATORS & others in the client’s environment agree with the procedure
  • if they don’t accept the intervention, they will NOT adhere to them in the future
70
Q

identify putative/supposed reinforcers (Rs)

A
  • success of ABA depends on effective Rs
  • R for 1 person may not R for another
  • sometimes hard to determine for ppl with intellectual disabilities
  • preferences are TRANSITORY: 1 thing may not always reinforcing. R changes with age, interest level, time of day, presence of MOs, etc
71
Q

2 procedure for identifying effective Rs

A
  1. stimulus preference assessment

2. reinforcer assessment

72
Q

stimulus preference assessment

A
  • identify stimuli that are LIKELY to function as Rs
    to determine:
  • stimuli that a person prefers
  • relative preference value of stimuli (high vs. low)
  • under which conditions the preference values CHANGE when task demands, deprivation states, schedule of R changes
73
Q

3 basic methods of stimulus preference assessment

A
  1. ask abt stimulus preferences
  2. free-operant observation
  3. trial-based methods
74
Q
  1. ask abt stimulus preferences
A

a. ask the person
- open-ended oral or written questions
- choice format
- rank objects on a list
- if the person has limited language, use pictures, nods/points as making a choice.
- not a sure-fire system. there may be discrepancies between a person’s claim & the real reinforce power

b. ask the sig. other
c. offer a pre-task choice: what do you want to earn for doing the task?

75
Q
  1. free-operant observation
A
  • record what activities a person engages in when they can CHOOSE during a period of UNRESTRICTED access to numerous activities
  • CONTRIVED free-operant observation: the practitioner fills the environment with a variety of items that the person may like
  • NATURALISTIC free-operant observation: conduct in the learner’s EVERYDAY environment as UNOBTRUSIVELY as possible. the observer records how the person allocates time with each activity
76
Q

3 ways to measure a learner’s B

A

measure how a learner responds to stimuli in free-operant observation & trial-based methods:

  1. approach: any DETECTABLE movement toward the stimulus
  2. contact: touch/hold the stimulus
  3. engagement: total time/percentage of intervals that interact with the stimulus

the MORE a person approaches, touches, engages with a stimulus, the MORE likely he prefers it

  • high preference - HP
  • medium preference - MP
  • low preference - LP
77
Q
  1. trial-based methods
A

stimuli are presented to the learner in a series of trials, measure the learner’s responses to the stimuli as an index of preference

  1. paired stimulus / force choice
  2. multiple stimulus
  3. single stimulus / successive choice
78
Q
  1. paired stimulus / force choice
A

SIMULTANEOUS present 2 stimuli

  • observer records which one the learner chooses
  • data reflects how many times each stimulus is chosen
  • rank stimuli as low, medium, high preference
  • sometimes more efficient than single-stimulus presentation
  • takes more time coz EVERY PAIR of stimuli must be presented
79
Q
  1. multiple stimulus
A

SIMULTANEOUS present 3 or more stimuli
- reduce assessment time

  1. multiple stimuli with replacement: the chosen item remains in the array, replace the ones that are not chosen
  2. multiple stimuli without replacement: the chosen item is removed, rearrange the order or placement of not chosen items & next trial begins
80
Q
  1. single stimulus / successive choice
A
  • most basic method for assessing preference
  • suit for ppl who has a hard time selecting among 2 or more stimuli
  • target stimuli among all SENSORY: visual, auditory, vestibular, tactile, olfactory, gustatory, multisensory
  • present 1 at a time in RANDOME order, record the person’s reactive to each stimuli
  • record approach / rejection: occurrence (yes/no), frequency, duration
  • after recording, the next item is presented
  • present several time & varied order
81
Q

select stimulus preference assessment method

A
  • monitor learner’s activities before the assessment to be aware of MOs
  • balance cost-benefit
  • use fewer items in an array if time is brief
  • combine multiple assessment methods
82
Q

reinforcer assessment

A
  • direct, data-based methods used to present 1 or more stimuli contingent on a TARGET response & then measure the FUTURE effects on the RATE of responding
  • use to determine the RELATIVE effects of a given stimulus as R under DIFFERENT & CHANGING conditions
  • to assess the comparative effectiveness of multiple stimuli as Rs for a given B under certain conditions
  • put the potential Rs to a DIRECT test: present them contingent on occurrences of a B, measure any effects on response RATES
  • the ONLY way to know for sure whether a stimulus serves as R: present it IMMEDIATELY after the occurrence of the B, measure its effects on RESPONDING
83
Q

a. concurrent schedule reinforcer assessment

A
  • 2 ore more contingencies of R operate INDEPENDENTLY & SIMULTANEOUSLY for 2 or more Bx
  • show the RELATIVE effectiveness of HP & LP
  • to determine differences between relative & absolute R effects
  • matching law
84
Q

b. multiple schedule reinforcer assessment

A
  • present 2 or more component schedule of R (FI, VI, FR, VR) for a SINGLE response, ONLY 1 component schedule in effect at a given time
  • an SD signals the presences of each component schedule & the SD is present as long as the schedule is in effect
85
Q

c. progressive-ratio schedule reinforcer assessment

A
  • assess the relative effectiveness of a stimulus as R as response requirement INCREASE
  • requirement of R are increased SYSTEMATICALLY over time INDEPENDENT of the participant’s B
  • the practitioner gradually requires MORE responses per presentation of preferred stimulus until a BREAKING POINT & the response rate declines
86
Q

identify potential punishers

A
  • what is punishing for 1 person may not be for another
  • sometimes hard to determine for intellectual disabilities
  • punishers are transitory
87
Q

punisher assessment

A
  • same as R assessment

advantage

  • the sooner it can be identified, the sooner it can be used to treat problem Bx
  • informs the INTENSITY of the punisher needed to effectively decrease / eliminate the problem B
  • want to use the SMALLEST intensity of the punisher when it is effective
  • measure -ve verbalizations, avoidance movements, escape attempts associated with each potential punishing stimulus
  • use data from punisher assessment to develop hypothesis on the relative effectiveness of each stimulus change as a punisher
