ABA 2 Spring 2011Terms and Definitions

Session #1 and Content Area 2

Analogue FA

Setup conditions to mimic real-life situations
Analogue FA conditions
Control, attention, escape from task, alone, tangible
Characteristic of ABA. Scientifically based experimental designs are used to assess the effectiveness of interventions under study.
Antecedent Manipulation
Adding or removing antecedents that evoke behaviors. Include MO, SD, response effort
Antecedent Manipulations (5)
1. Antecedent control procedure
2. Establishing Operation
3. Present SDs for appropriate behavior
4. Remove SDs for inappropriate behavior
5. Increase response effort for inappropriate behavior
Characteristic of ABA. Focuses on behavior with social significance.
Applied Behavior Analysis vs Experimental Analysis of Behavior
Both use systematic manipulations and data analysis of individual organisms.
ABA: Behaviors of social significance to the person are investigated
EAB: Behaviors of no social significance of the person are investigated
Assumptions/Characteristics of Science
1. Determinism
2. Law of Parsimony
3. Scientific Manipulation
4. Empiricism
5. Philosophic Doubt
6. Replication
Automatic reinforcement
A reinforcer that is produced by the behavior without the participation of other people. For example, echolalia produces sounds that may maintain the behavior. It can be positive or negative reinforcement.
Characteristic of ABA. Behavior is the focus, not a hypothetical entity.
Behavioral Assessment
Assessment that examines the person's entire life in order to identify possible causes of the behavior in question. You may use descriptive assessment methods or functional analyses.
Behavioral assessment: 2 general kinds
1. Functional analysis
2. Descriptive assessment
Behavioral assessment: goal
Identify the function of behavior
Behavioral Technologies
Collection of procedures that have arisen from research and are applied to practical problems by practitioners. Ex: behavioral momentum is now implemented by many service providers in clinics, schools, and homes
Philosophy of behavior that assumes behavior is a function of current and past environments as well as genetics.
Characteristics of ABA
1. Effective
2. Technological
3. Conceptually Systematic
4. Generality
5. Analytic
6. Applied
7. Behavioral
Conceptually Systematic
Characteristic of ABA. Procedures are tied to the basic principles of behavior.
Dependent Variable
Measure of behavior of interest
Assumption of Science. Behavior is caused by some event.
Discrepency analysis
Compare data with those of norm group to determine changeworthiness of current behavior
Divided attention
When attention is diverted to another person, and not just withheld
Characteristic of ABA. Attempt to produce large enough effect that has an impact on the person's life.
Assumption of Science. Information is collected by objective observations
Explanatory Fiction/Circular Reasoning
Explaining behavior by using entity that lies within the behavior itself. (Eric is aggressive because he has an aggressive trait. Evidence of aggressive trait is his aggressive behavior)
Functional Analysis
Manipulation of environmental conditions to determine a functional relation between problem behavior and independent variables. Goal is to confirm hypothesis developed in descriptive assessment.
Functional analysis best practice: how many controls to use
Use one control for each test (pair wise)
Functional analysis best practice: natural vs contrived environments
Functional analysis best practice: role of supplemental information
To develop an hypothesis
Functional analysis best practice: what to do with tangible condition
If descriptive assessment does not indicate behavior occurs to produce tangibles, then don't include in test conditions.
Functional analysis models
AB and ABC
Functional analysis on high intensity behavior
1. Look at the latency to the first response in the condition. Then end the condition.
2. Or, just study precursors.
Functional analysis review: most common function
1. Escape from task
2. Attention
Functional analysis review: most common population studied
Kids with disabilities
Functional analysis review: most common setting
Inpatient settings
Functional analysis: AB model
FA in which an EO is manipulated (task vs no task; frequent attention vs low attention). No consequences are presented when behavior occurs.
Functional analysis: ABC model
FA in which EO and consequences are manipulated. Attention condition: FR 1 attention for problem behavior when attention deprived. Tangible condition: FR 1 tangible for problem behavior when tangible deprived.
Functional analysis: brief
An FA that involves 1 or 2 sessions
Functional analysis: limits
1. Does analogue apply to real life
2. Sometimes misses idiosyncratic variables
3. Doesn't always investigate complex variables
Functional Analysis: Multi-Component Manipulations
Arranging for particular conditions/situations (task, alone, enriched environment, etc) and measuring behavior. Reinforcers may be provided for problem behavior.
Functional analysis: Pair wise
When a particular test condition (e.g., FR 1 attention) has a corresponding control condition (e.g., continuous attention). A pair wise is often used to test a particular hypothesis (e.g., is the behavior maintained by attention?).
Functional analysis: role of precursors
Can be the DV if the problem behavior is dangerous.
Functional analysis: strengths
1. High degree of confidence in determining functional relations
Functional analysis: undifferentiated data
This suggests that the behavior is under multiple control (there is more than 1 operant) - or it may suggest that there is some idiosyncratic variable that is maintaining the behavior in all conditions.
Extent to which the results or functional relations will be observed if the experiment is changed in some way. Can be tested by implementing the Tx with different Ss, settings, behaviors, or species.
How to sample high rate behavior
Continuous recording for short period of time
Hypothesis testing (2 kinds)
1. Tx vs no Tx probes in real life setting
2. Set up FA conditions to test hypothesis
Inadequate Explanations of Behavior
1. Nominal Fallacy
2. Teleology
3. Reification
4. Circular reasoning
Independent Variable
Treatment or intervention
Kinds of descriptive assessments
1. Direct observation
2. Records review
3. Interviews
Law of Parsimony
Assumption of Science. The simplest explanation of behavior should be provided, all else being equal
Maladaptive behavior: problem with term "maladaptive"
It is assumed that behavior is adaptive, as it has a function.
Mentalistic Explanations of Behavior
Explanations that appeal to mental, unobservable processes. Ex: The child was aggressive due to his frustration with school.
Nominal Fallacy
Explaining behavior by naming or classifying it (The behavior is PICA to explain eating inedible objects)
Philosophic Doubt
Assumption of Science. Conclusions of science are tentative and can be revised as new data comes to light.
Precursors: role in assessment
In the case of high intensity behavior, precursors maybe assessed for safety reasons
Precursors: role in treatment
It can be useful to intervene, and treat, precursor behavior: 1) less restrictive procedures can be used 2) a given Tx maybe more effective, as precursors are earlier in the chain and therefore maybe weaker
Private Events
Behavior and/or stimuli that can only be observed by the person. (Ex: headaches) These behaviors and stimuli still must be explained by appealing to a history of environmental contingencies or biological processes.
Problem with analogue FA – with respect to generality of results
Analogue setting sometimes unlike real-life. Thus, poor generality.
Proximal MO example
1. Task presented to child --> problem behavior
Reasons why you might need to intervene
A. Danger to self, others
B. Safety hazard
C. Welfare in current environment
D. Behavior problem prevents access to less restrictive environment
Explaining behavior by appealing to non-existent entity (ID, ego, self, etc.)
Scientific Manipulation
Characteristic of Science. Systematically manipulating an event to see effects on behavior
Setting events: issue with term
Setting events is not technical term in the field. They typically refer to motivational operations
Social Significance
Characteristic of Applied Behavior Analysis whereas the behavior is socially significant to the person as well as the changes that occur.
Systematic Manipulation
Assumption of science. To see if an event affects behavior, the event is systematically manipulated and the effects on behavior are noted.
Characteristic of ABA. Provides written detail of procedures to permit replication of techniques in other settings.
Explaining behavior by appealing to future, unexperienced events (I am doing my homework to graduate)
What is Behaviorism?
Philosophy of behavior that assumes that behavior is a function of past and current events as well as genetics.
What is the difference between Applied and Experimental Analysis?
The difference is that with Applied the behaviors have social significance to the person being investigated whereas with Experimental Analysis they do not.

Withholding a stimulus that normally occurs after a behavior, resulting in a decrease in the rate of behavior.
Extinction Side-Effects
Extinction burst, emotional behavior, aggression, increase in variety of topographies, increase in intensity of behavior
Free Operant
Behavior that can occur at anytime, given some motivation.
Functional Response Definition
Includes the topography of response as well as the functional antecedents and/or consequences.

Social Learning Theory
Theory of learning that posits learning occurs as a result of observations that subsequently affect the person through cognitive mediational processes.
Spontaneous Recovery
Following an extinction session, a temporary re-appearance of the behavior in the beginning of the next extinction session. It is thought that the re-appearance is due to the relative novelty of the "beginning of the session" that was only briefly experienced in the previous session.

Complete Behavioral Support Plan
4 Elements: motivational operations, discriminative control, replacement behaviors and consequence manipulations
Conditional probability
The likelihood of an event occurring, given another event (e.g., how often a behavior occurs, given an antecedent). Formula: #A--> B/ # A OR # B --> C/# B.
Contextual Variables (setting events)
Variables that are more generally present stimuli that are not necessarily manipulated as part of a behavior change program. May influence the efficacy of behavioral procedures. Ex: medical status, task variation, number of staff, etc.
Dependent Group Contingency
Reinforcer for a group depends on the behavior of a single person or small # of people
Direct Solutions to Behavior Problems
Solutions to behavior problems that do not involve formal behavior programs. Ex: treating a medical condition, removing an antecedent stimulus, changing some feature of the environment, etc.
Ecological Changes
Changing schedules, staffing patterns, activities, diet, etc.
How to compute conditional probability of A-B sequences
# A-->B / # A
How to compute conditional probability of B-C sequences
# B-->C / # B
Interventions that follow from assessment
Ecological changes, antecedent manipulation, replacement skills, change consequences of appropriate and inappropriate behaviors, emergency procedures, motivational operations
Lag 1
1. Lag 1 - Examines the liklihood that an event occurs given another event that occurs just before.

A --> B
Lag 2
2. Lag 2 - Examines the liklihood that an event occurs given another event that occurs 2 events prior.

A2 --> A --> B
Lag sequential analysis
Computations that examine the liklihood that an event will occur given another event.
Lag sequential analysis
When conditional probabilities are calculated. It can be between an A and B, or between a B and C. Formula for A and B: Prob(A-->B)/Prob(A). Formula for B and C: Prob(B-->C)/Prob(B)
Lag sequential analysis: Lag 1
When conditional probabilities are calculated. It can be between an A and B, or between a B and C. Lag 1 refers to the fact that the CP examines the A just before the B, or the C just after the B.
Lag sequential analysis: Lag 2
When conditional probabilities are calculated. It can be between an A and B, or between a B and C. Lag 2 refers to the fact that the CP examines the A that is two antecedents before the B, or the C that is two consequences after the B.
Measure for task completion
# tasks and # tasks given
Naturalistic behavioral assesment
Behavioral assessment that occurs in the natural environment.
Pattern Analysis
Looking for patterns of behavior, noting any kind of correlation of behavior and some other factor. Ex: time of day, staff, curriculum, etc. Common type of pattern analysis is scatterplot.
Consuming inedible items (e.g., screws, bolts, small toys)
Replacement Skills
New skills that are taught to replace target behaviors in order to obtain the same reinforcer
Sequence Analysis
Identifying events that typically precede and follow a target behavior. Also called ABC Analysis.
Testing Hypothesis in Functional Analysis
Conditions are arranged to test the hypothesis. Ex: to assess behavior thought to occur for attention, compare condition in which attention is given after behavior with that where attention is withheld after behavior.

Session #6 & Content Area 5

Alternating Treating (multi-element) Design

Two or more treatments with their own signal, alternated across time - usually in the same day.
Between subject designs
Participants only receive 1 condition (e.g., BL or TX). The mean of each group is typically reported.
Changing Criterion
A design in which criterion in reinforcement is systematically changed. Control is shown when changes in behavior shadow changes in criterion.
Component Analysis
Taking treatment apart and identifying which component is the effective component. Can be accomplished by slowly taking each element out -or- by starting with a single element and slowly adding each element.
Confounding Variable
Uncontrolled variables or events that influence the outcome of an experiment. Often accompany the IV and thus are indistinguishable from the IV.
Two events co-vary. One may cause the second, the second may cause the first, or both may be caused by a third variable.
Deductive Processes
Testing hypothesis by collecting data in systematic manipulation format.
Direct Replication
Repeating the exact experiment with the same (intra-subject) or similar subjects (inter-subject). When used with the same participant, allows for assessment of internal validity.
Experimental Design
A sequence of conditions that permit conclusions about whether the changes in behavior resulted from the intervention
External Validity
Extent to which intervention can be successfully applied to other people, other situations, or other behaviors. Also termed generality.
Functional Relation
When an independent variable lawfully affects a dependent variable
Inductive processes
Generating a hypothesis from data that has already been collected.
Integrity of the Independent Variable
Refers to the extent to which the treatment is implemented as intended.
Internal Validity
Whether or not changes in behavior can be attributed to the intervention. AB designs lack strong internal validity, but ABA or ABAB designs have strong internal validity.
Multiple Baseline (3)
Baseline data are collected on two or more subjects, situations, or behaviors. Intervention is applied to the first, and then the first and second, etc.
Multiple Probe
Multiple baseline design except that untreated behaviors are assessed periodically through probes until they receive the intervention.
Parametric Analysis
Studying different values or levels of a treatment. Can be accomplished by randomly presenting the different values in a ABCDEF design varied across participants -or- by presenting the values in an ascending/descending series in ABCDEDCBA design. This design is often used in drug studies.
Practical Issues with Alternating Treatments Design
Effects of one treatment can be seen in other conditions due to rapid alternation. If treatment procedures are not discriminable, differences may not be evident in data.
Practical Issues with Changing Criterion Design
Not all behaviors/treatments can be studied with this design. In some cases, a reinforcement parameter may be able to be varied.
Practical Issues with Multiple Baseline Design
Requires untreated behaviors, participants or settings which could be dangerous. Internal validity can be unclear when generalization occurs.
Practical Issues with Withdrawal & Reversal Designs
1. Requires counter-therapeutic change
2. Not appropriate for irreversible changes
3. SIB can be dangerous in this design
Rate/min issue
Rate/min is a measure of celeration. If a rate measure is needed, use # beh/min.
Reversal Design
A design in which an intervention is applied to behavior, then removed and a second intervention is applied to the same behavior (ex: NCR), and then the second intervention is removed and the first is re-applied.
Steady state
When data show no trend according to some criterion (e.g., no visible trend over 5 sessions)
Systematic Replication
Purposefully changing elements of the experiment and repeating the new experiment. Displays external validity or generality.
Threats to Internal Validity
Events that call into question whether the changes in behavior resulted from the treatment. Include maturation of the subject(s), inaccurate or biased recording, poor implementation of the treatment, unplanned environmental changes, etc.
Transition state
When there is a trend in the data, and there is presumably an ongoing behavioral process that is changing the strength of the behavior. Transition states occur between steady states.
Withdrawal Design
Design in which baseline conditions are alternated with intervention conditions. Minimum alternations are ABA or BAB.
Withdrawal with Probe Design
A standard ABAB design except the return to the A condition is very brief.
Yoking: between subject
Between subject yoking: when some parameter in a condition is used in another condition for a different subject (e.g., one subject, called the master, is responding under a FR 5 condition. When this subject earns a reinforcer, another subject receives a reinforcer. This would be used to generate a VT schedule for the "slave." ).
Yoking: within subject
Within subject yoking: when some parameter in a condition is used in another condition for a subject (e.g., the rate of reinforcement in a FR 5 condition is used to program a FT schedule in another condition).

Session #7 and Content Area #6

ABC recording

Recording antecedent, behavior, consequence streams. Used in descriptive assessments.
Presumed to be present when there is agreement between 2 trained observers. But more correctly, when data are consistent "true values."
Behavior Definitions
Observable and measurable description of behavior
Bias of partial interval recording, whole interval recording and momentary time sampling

Whole interval: underestimates rates, used for acquisition skills
Momentary time sampling: no systematic bias
A measure of the change in behavior over time (10/min --> 20/min = doubling)
Continuous vs. Sampling Recording
Continuous - uninterrupted observation and recording
Sampling - behavior observed and recorded occasionally
Descriptive analysis: limits
1. Sometimes inaccurate conclusions
2. Function might change over time
Descriptive analysis: strengths
1. Easy for practitioner

Event Recording
# of occurrences of a response are recorded.
Number of times a behavior occurs (Ex: count)
Functional equivalence
When two or more behaviors have the same effect (they belong to the same operant). This concept is often used in identifying a replacement behavior.
Grooming is when a person tries to ‘set up’ and ‘prepare’ another person to be the victim of sexual abuse.
Grooming: examples
1. giving inappropriate attention to childen
2. giving gifts
3. openly or accidentally exposing the victim to nudity and sexual material
4. sexualising physical contact, such as inappropriate tickling and wrestling
5. having inappropriate social boundaries (e.g., telling the potential victims about their own personal problems etc).
Force of behavior, which could be measured in decibels (loudness) or lbs/sq in (pressure)
Inter-observer agreement (IOA)
Extent to which two observer's data agree. It is said to estimate accuracy.
Inter-observer agreement (IOA): exact count per interval
1. Divide observation time into intervals
2. Count # of intervals in which there is exact agreement
3. Compute IOA for each interval by the (# of exact agreements/# total intervals) x 100

The assumption is that the independent variables are low rate
Low rate/high intensity behavior: Behavior assessment procedures
1. Descriptive assessment
2. Present SD/EO
Low rate/high intensity behavior: measurement
1. Focus on precursors
2. Latency instead of rate
Matching equation
Equation that expresses a fundamental functional relation: the rate of response will be sensitive to the rate of reinforcement for that response as well as the rate of reinforcement for other responses
R1 = r1
--------------- --------------
R1 + R2 r1 + r2
Matching equation: 2 ways to decrease R1
1) decrease the rate of reinforcement for R1 and 2) increase the rate of reinforcement for R2.
Momentary-Time Sampling
A recording procedure in which a time period is divided into bins. A "+" is recorded if the behavior occurs at the end of the bin. A "-" is recorded if behavior does not occur at the end of the bin. There is no systematic bias.
Motivational operation: distal
An MO that is temporally removed from a behavior - for example, several hours prior to the behavior that is strengthened.
Motivational operation: proximal
An MO that occurs close in time to a behavior
Narrative recording
On-line description of behavior, antecedents and consequences written in prose.
Observation Times for High Rate Behavior
Can be brief
Observation Times for Low Rate Behavior
Longer duration to catch the behavior
Observer drift
Tendency for an observer's recording to gradually change across time. It can be pinpointed to the time when an observer's scores differ from those of a 2nd observer. One cause is a change in response definition.
Partial Interval Recording
Recording procedure in which a time period is divided into bins. A "+" is recorded in each bin if a behavior occurs at all during that bin. A "-" is recorded if the behavior did not occur at all during that bin. This recording procedure tends to be an overestimate.
Attraction to pre-pubescent children
Percentage Correct
# of correct responses/ # of total responses, multiplied by 100
Permanent Product Recording
Recording the effects of the behavior, not the behavior itself (Ex: bed made)
#of responses/ time (Ex: responses/minute)
Extent to which the act of recording influences behavior (behavior changes when being observed)
Re-training an observer to increase accuracy, used to decrease/correct observer drift
Recording Procedures
Methods for recording behavior that produce data transposable into a measure
Extent to which a given measurement result will be obtained with the same sample of behavior - consistency!
Response class covariation
Operants contain various topographies. If the strength of one member of the operant is changed by reinforcement or punishment, then the strength of the other members is changed as well.
Response class covariation: role in treating low rate/high intensity behavior
May focus on treating lower intensity behavior in same class.
Sexual offenders Tx: role of confederates
1. They can act as observers in situations where offenses have occurred
2. Confederate can entice the offender into situations where offenses have occurred
NOTE: confederates should never put anyone at risk!
Sexual offenders Tx: Example of manipulating MO
Give drugs (e.g., Depo-Provera) to reduce value of sexual stimuli
Sexual offenders Tx: Example of manipulating SD
1. Remove opportunity for contact with inapp sexual stimuli
2. Provide opportunities for contact with appropriate sexual stimuli
