Behavior Modification (PSY 11)
Chapter 1: Introduction to behavior modification
Characteristics of behavior:
Involves actions, not labels.
Involves physical dimensions: Frequency, Duration, Intensity, Latency.
Can be observed, described, and recorded.
Has an impact on the environment (physical or social).
Behavior is lawful.
May be overt or covert; covert behaviors are private events (Skinner, 1974).
Defining behavior modification:
Behavior modification is the field of psychology concerned with analyzing and modifying human behavior.
Analyzing:
Identifying the functional relationship between environmental events and a particular behavior.
Helps understand the reasons for behavior or why a person behaved as they did.
Modifying:
Developing and implementing procedures to help people change their behavior.
Involves altering environmental events to influence behavior.
Characteristics of behavior modification (key features):
Focus on behavior: target behavior is specified; traits or labels are avoided; behavioral excesses or deficits.
Based on basic behavioral principles.
Emphasis on current environmental events: antecedents and consequences.
Precise description of procedures.
Treatment implemented by people in everyday life.
Measurement of behavior change: immediate and long-term.
De-emphasis on past events as causes of behavior.
Rejection of explanatory fictions ( Skinner, 1974 ).
Terms and framework:
Experimental analysis of behavior (behavior analysis): scientific study of behavior.
Applied behavior analysis: scientific study of human behavior.
Behavior modification procedures are based on ABA research.
ABA is the science; behavior modification is the technology.
Historical roots (highlights):

1950s: Behavior modification with humans.
1953: Skinner – Science and Human Behavior.
1957: Skinner – Verbal Behavior.
1958: Journal of the Experimental Analysis of Behavior (JEAB) founded.
1963: Behaviour Research and Therapy (BRAT) founded.
1966: Association for Advancement of Behavior Therapy established.
1968–1980s–2000s: Journal of Applied Behavior Analysis, Behavior Therapy, etc.; continued research; functional analysis approach; certification in behavior analysis.
Chapter 1: Areas of application (brief overview):
Developmental disabilities, mental illness, education and special education, rehabilitation, community psychology, clinical psychology (counseling), business/industry/human services.
Organizational behavior modification/management, self-management, child management/parenting, prevention, sports psychology, health-related behaviors, gerontology.
Chapter 2: Observing and recording behavior
Purposes of behavioral assessment:
Decide if a problem exists (Is treatment necessary?).
Decide on the best treatment.
Measure treatment effects.
Can be a treatment component itself (reactivity).
Types of behavioral assessment:
Indirect assessment: interviews, questionnaires, rating scales.
Direct assessment: direct observation and recording of the target behavior as it occurs.
Recording the target behavior:
Define the target behavior.
Determine recording logistics (who, when, where).
Choose recording method.
Choose recording instrument.
Consider: reactivity; interobserver agreement (IOA).
Defining the target behavior:
Describe what the person does and says (avoid labels).
Use active verbs (objective, unambiguous).
No inferences about internal states or motivation.
Defined so that two people could agree.
IOA (interobserver agreement).
Logistics of recording:
Who should record: independent observer, self-monitoring.
When and where: define observation periods; natural vs contrived (analogue); structured vs unstructured.
Recording methods:
Continuous recording:
Frequency: rate = Frequency / Time of observation period.
Duration.
Latency.
Intensity (magnitude).
Real-time recording.
Other methods:
Percentage of opportunities.
Product recording (permanent product).
Interval recording: partial vs whole interval; frequency-within-interval recording.
Time sampling.
Recording instruments and practicality:
Data sheet (paper/pencil).
PDA/laptop; stop-watch; various counters; practical immediacy.
Reactivity and IOA (interobserver agreement):
Reactivity: recording itself can change the behavior.
Reducing reactivity: acclimate observer; surreptitious recording; participant observers.
IOA definitions:
IOA = percentage of agreement between independent observations.
For frequency or duration: IOA = .
For interval/time-sample recording: IOA = number of intervals with agreement / total intervals.
For frequency within-interval recording: IOA calculated as percent agreement in each interval, then averaged.
Chapter 3: Graphing behavior and measuring change
Graphs:
Visual representation of behavior over time.
Facilitate comparison of level before, during, after treatment; used to evaluate behavior change.
Components: Y-axis (ordinate), X-axis (abscissa); axis labels; axis numbers; data points; phase lines; phase labels.
Purpose of research in behavior modification:
Evaluate treatment effectiveness.
Demonstrate a functional relationship between environmental events/procedures and behavior.
Methods: measure dependent variable (target behavior); manipulate independent variable; control extraneous variables; replication.
Behavior modification research designs:
A-B design: one baseline, one treatment; not a true research design; no replication; used in clinical practice/self-management.
A-B-A-B reversal design: baseline and treatment phases repeated; demonstrates functional relationship; ethical considerations about removing treatment.
Multiple-baseline design:
Across subjects; across behaviors; across settings.
Alternating-treatments design (ATD): rapid alternation of conditions to compare treatments.
Changing-criterion design: baseline and treatment with multiple performance criteria; demonstrates functional relationship when behavior matches criteria.
Part 2: Basic principles
Chapter 4: Reinforcement
Reinforcement defined (functional):
The occurrence of a behavior is followed immediately by a consequence that strengthens the behavior (more likely to occur again in similar circumstances).
In the present: behavior followed by a consequence; in the future: behavior more likely to occur.
Operant behavior and reinforcers:
Operant: behavior that operates on the environment to produce a consequence; behavior is controlled by that consequence.
Reinforcer: the consequence that follows and strengthens operant behavior; can be an opportunity to engage in a preferred behavior (Premack principle).
Types of reinforcement:
Positive reinforcement: behavior followed by presentation of a reinforcing stimulus; strengthens behavior.
Negative reinforcement: behavior followed by removal of an aversive stimulus; strengthens behavior (escape and avoidance).
Escape: behavior terminates aversive stimulus.
Avoidance: behavior prevents aversive stimulus.
Reinforcement in everyday examples (negative reinforcement):
Examples include turning the channel, putting on a coat, using an umbrella, etc.
Positive and negative reinforcement in the same situation:
Tantrum in a grocery store: candy from parent acts as positive reinforcement for tantrum; removing tantrum by candy also strengthens parent’s behavior (negative reinforcement) to give candy.
Social vs. automatic reinforcement:
Social reinforcement: consequence delivered by another person.
Automatic reinforcement: consequence produced directly by the environment.
Reinforcers by basic type:
Unconditioned (primary) reinforcers: biologically-based (food, water, warmth, oxygen, etc.).
Conditioned (secondary) reinforcers: previously neutral but paired with reinforcers (sight, sound, praise, money, etc.).
Generalized conditioned reinforcers: paired with many reinforcers (money, praise, tokens).
Factors influencing reinforcement:
Immediacy (contiguity).
Consistency (contingency).
Motivating operations (MOs): Establishing operation (EO) increases reinforcer potency; Abolishing operation (AO) decreases potency.
Individual differences.
Magnitude/intensity of the reinforcer (inverted-U effect possible).
Schedules of reinforcement:
Continuous reinforcement (CRF): every response is reinforced; used during acquisition.
Intermittent/partial reinforcement (PRF): not every response is reinforced; used for maintenance.
Ratio schedules: FR (fixed ratio) and VR (variable ratio).
Interval schedules: FI (fixed interval) and VI (variable interval).
Concurrent schedules: reinforcement for two or more behaviors simultaneously; factors influencing choice include schedule, magnitude, immediacy, and effort; consider all plausible alternative behaviors.
Additional reinforcement topics:
Contingency descriptions: ΔP as a statistical measure of contingency; relation to terms positive/negative reinforcement and continuous/partial reinforcement.
Appetitive vs. aversive stimuli/outcomes.
Circularity of the functional definition of reinforcement; intrinsic vs. extrinsic motivation.
Practical notes on reinforcement:
Real-world examples showing how reinforcement can be viewed from multiple perspectives (e.g., some instances of positive reinforcement may be viewed as negative reinforcement).
Chapter 5: Extinction
Extinction = a previously reinforced behavior is no longer reinforced, leading to weakening of the behavior (decrease in future probability).
Extinction burst: initial escalation in frequency, duration, or intensity; appearance of novel behaviors; increased arousal/anticipation.
Spontaneous recovery: behavior reappears after some time; renewal of responding.
Procedural variations:
Extinction of positively reinforced behavior: continue response → reinforcer no longer occurs.
Extinction of negatively reinforced behavior: aversive stimulus is not removed following the response.
Factors influencing extinction:
Prior reinforcement schedule: CRF leads to rapid extinction; PRF leads to resistance to extinction.
Occurrence of reinforcement following extinction initiation: occasional reinforcement during extinction can sustain/resist extinction.
Reinforcement of functionally-equivalent behaviors can facilitate extinction.
Chapter 6: Punishment
Punishment = a behavior is followed immediately by a consequence that decreases the future probability of the behavior.
Punisher (aversive stimulus); can be a nonpreferred behavior is forced (Premack principle).
Important nuance: punishment can be viewed as suppression, not strengthening (textbook framing); emphasized by some as weakening the target behavior.
Types:
Positive punishment: behavior followed by presentation of an aversive stimulus; decreases future probability.
Negative punishment: behavior followed by removal of a reinforcing stimulus; decreases future probability.
Other names: punishment by application/contingent presentation; punishment by withdrawal/loss of reinforcers; penalty contingencies.
Punishers: unconditioned punishers (biological relevance) vs conditioned punishers (previously neutral stimulus paired with a punisher).
Relationship to reinforcement/punishment matrix: different outcomes depending on whether a reinforcement is added/removed or a punisher is added/removed.
Factors influencing punishment: immediacy, consistency, MOs, magnitude, individual differences.
Potential problems: emotional reactions, escape/avoidance, negative reinforcement for the use of punishment, modeling, ethical issues.
Chapter 7: Stimulus control: Discrimination and generalization
Stimulus control focuses on antecedents; reinforcement/extinction/punishment effects are situation-specific.
Discrimination: behavior occurs in the presence of a discriminative stimulus (SD) and is reinforced; SΔ presence signals non-reinforcement.
Generalization: behavior occurs in the presence of stimuli similar to the SD; generalization gradient; stimulus class; generalization may reflect discrimination failure or can be enhanced with training.
Three-term contingency (Skinner, 1969):
SD → R → SR (reinforcer) in reinforcement.
SD → R → SP (punisher) in punishment.
SD/SΔ terminology:
SD: discriminative stimulus; SΔ: S-delta (stimulus signaling non-reinforcement).
Stimulus control training:
Discrimination training: reinforce in presence of SD; do not reinforce in presence of other antecedents (SΔ).
Result: behavior more likely in presence of SD.
Examples of SD/SΔ outcomes and contingencies.
Chapter 8: Respondent conditioning (Pavlovian conditioning)
URs (unconditioned responses) are innate; elicited by US (unconditioned stimulus).
Respondent conditioning: US → UR; NS paired with US → CS → CR.
CS becomes conditioned stimulus; CR is conditioned response.
Timing relations between CS and US (various delays): trace, delay, simultaneous, backward; timing strength varies with response system.
Higher-order conditioning: CS2 paired with CS1, CS2 → CR.
Conditioned emotional responses (CERs): fear, anxiety, anger; examples include Little Albert (Watson & Rayner).
Extinction and spontaneous recovery for conditioned responses.
Discrimination and generalization of respondent behavior.
Factors influencing respondent conditioning: salience of CS/US, contiguity, contingency, number of pairings, prior exposure.
Comparison: respondent conditioning vs operant conditioning; roles of antecedents vs consequences.
Integration: both types of conditioning can occur together in real-world behavior (e.g., fear responses and avoidance strategies).
Part 3: Procedures to establish new behaviors
Chapter 9: Shaping
Shaping = differential reinforcement of successive approximations to a target behavior.
Two principles: reinforcement and extinction.
When to use shaping:
To develop new topographies (forms) of behavior.
To develop new dimensions; to reinstate old behaviors.
When instructions/modeling/prompting are not effective.
Applications: language development; teaching rats to press a lever; animal training; rehabilitation; voice volume; medical procedures compliance.
Using shaping: steps
1) Define the target behavior.
2) Determine if shaping is appropriate; use differential reinforcement if already occurs.
3) Identify starting behavior that is already exhibited.
4) Choose shaping steps (successive approximations).
5) Choose reinforcer; beware satiation; use conditioned reinforcers if needed.
6) Differentially reinforce each successive approximation.
7) Move through shaping steps at proper pace.Shaping of problem behaviors (examples): tantrums, nagging, showing off, dog begging, self-injury.
Chapter 10: Prompting and transfer of stimulus control
Purpose: develop stimulus control and new behaviors; examples across domains.
Prompt definition: an antecedent stimulus that controls a response; helps the correct behavior occur in the correct situation.
SD (+ prompt) → R → SR
Types of prompts:
Response prompts (behavior of another person): Verbal, Gestural, Modeling, Physical prompts.
Stimulus prompts (changes to the antecedent): Within-stimulus prompts; Extra-stimulus prompts.
Examples: SD (prompt) → R → SR; baseball example; written word example.
Transfer of stimulus control: moving from prompting to independent performance via fading.
Fading: prompt fading; stimulus fading; prompt delay.
Prompt fading methods: least-to-most, most-to-least; stimulus fading examples.
Before prompting: determine problem type (can’t do vs won’t do).
Using prompting and fading: steps include selecting prompting strategy, getting attention, presenting SD, prompting, reinforcing, fading, and maintaining unprompted responses with intermittent reinforcement.
Chapter 11: Chaining
Behavioral chain = stimulus–response chain; each R produces an SD for the next R; final SR.
Task analysis: break chain into component S–Rs; identify all stimuli and responses.
Example: Eating oatmeal with steps from bowl to eat.
Chaining procedures:
Backward chaining: teach last component first; progressively earlier components.
Forward chaining: teach first component first; progress forward.
Training sequence for each component:
1) Present SD.
2) Provide verbal/physical prompts.
3) Praise for correct response.
4) Fade prompts.
5) When no prompts are needed, move to next component.
6) Repeat until all components learned.Important distinction: backward chaining often provides natural reinforcement on every trial; forward chaining may require artificial reinforcers for earlier steps.
Total task presentation: execute whole chain on each trial; use graduated guidance and fade to independent performance; reinforce independent behavior; consider task complexity and learner level.
Other chaining methods: textual prompts, picture prompts, video modeling, self-instructions.
Using chaining: determine if chaining is appropriate; construct task analysis; baseline; choose approach; implement; collect data; maintain with reinforcement.
Chapter 12: Behavioral skills training (BST) procedures
BST used to teach new behaviors that can be simulated in role-plays; suitable when learners can follow instructions/imitate models; may be used in groups.
BST components:
Modeling (live or symbolic).
Instructions.
Rehearsal.
Feedback.
Modeling: factors affecting effectiveness include reinforcing the model, model status, appropriateness of complexity, attention, context, repeat modeling, variety of exemplars, immediate reinforcement of correct imitation.
Instructions: specific, sequential, context-appropriate; ensure learner understands; credible instructor; pair with modeling when needed; deliver when learner is attentive; allow rehearsal after instructions; learner should be able to repeat instructions.
Rehearsal: learner practices after instructions/modeling; assess learning, reinforce, correct errors; factors include timing (immediately after instructions), practicing in the SD → R → SR context, easier-to-harder progression, immediate praise, corrective feedback, repeat rehearsal.
Feedback: praise for correct performance; corrections as needed; timely, descriptive, not overly negative; provide feedback on one aspect at a time; reinforce some aspect of performance before corrective feedback.
Enhancing generalization after BST: promote use in real settings via varied role-plays, real-life integration, in situ assessment/training, assignments, and natural environment reinforcement.
BST and three-term contingency: antecedent → behavior → consequence; role-play context, modeling, feedback, rehearsal, praise.
BST in groups: advantages (efficiency, multiple models, observation/feedback); disadvantages (less individualized attention).
BST applications: parenting, assertiveness, social skills, abduction prevention, gun-avoidance skills.
BST implementation steps (summary): identify skills, identify SDs, baseline assessment, start with easiest, describe/model behavior, allow rehearsal, provide praise/feedback, repeat until mastery, advance to next skill, generalize.
Part 4: Procedures to increase desirable behaviors and decrease undesirable behaviors
Chapter 13: Understanding problem behavior through functional assessment
Functional assessment (basic principle): behavior is lawful and controlled by environmental variables; behavior is a function of environmental variables.
Definition: process of gathering information about antecedents and consequences that are functionally related to a problem behavior.
Information gathered includes: three-term contingency (antecedent stimuli that evoke the behavior; the behavior itself; reinforcing consequences that maintain it).
Use of functional assessment data:
Identify alternative, functionally relevant behaviors.
Consider motivational variables (MOs) and stimuli that function as reinforcers.
Review history of treatments/outcomes.
What to assess:
Antecedents: SDs, SΔs, MOs; when/where/with whom/under what circumstances behavior occurs; social/environmental antecedents.
Behavior: problem behavior, alternative behavior, response effort.
Consequences: reinforcement (positive/negative); what the person gets from the behavior; social/environmental consequences; schedule/magnitude/immediacy of reinforcement.
Functions of problem behaviors (reinforcement categories):
Social positive reinforcement (attention, praise, reactions, activities, things) mediated by others.
Social negative reinforcement (escape from tasks/activities) mediated by others.
Automatic positive reinforcement (sensory stimulation).
Automatic negative reinforcement (relief from pain, anxiety, or aversive stimulation).
Examples (summaries):
4-year-old tantrums: social-positive (antecedent denied, consequence = thing requested delivered).
4-year-old tantrums: social-negative (requests during preferred activity; escape from task).
6-year-old autistic hand-waving: automatic-positive (not engaged; visual stimulation).
10-year-old wrist-biting: automatic-negative (alone, negative thoughts; relief from thoughts).
Additional examples cover teen hair-pulling, attention seeking, etc.
Functional assessment methods:
Indirect methods (informant assessment): behavioral interviews, standardized questionnaires, rating scales; advantages: easy, quick; disadvantages: memory bias; use multiple methods for accuracy.
Direct observation methods (ABC observation): observer records antecedents, behaviors, consequences in real time; advantages: more accurate; disadvantages: time-consuming; cannot prove causality (correlation vs functional relation).
ABC observations can be descriptive, checklist, or interval/real-time; conduct in the natural environment; plan in advance where/when the behavior occurs.
Indirect and direct methods are descriptive and hypothesis-generating; experimental methods are needed to demonstrate functional relationships (functional analysis).
Experimental methods (functional analysis):
Manipulate antecedents and/or consequences to demonstrate a functional relationship.
Advantages: high scientific evidence for controlling variables.
Disadvantages: time-consuming; requires expertise.
Conducting a functional assessment (stepwise):
1) Start with indirect assessment (interview).
2) Develop hypothesis about antecedents/consequences (function).
3) Conduct direct observation assessments.
4) Confirm/modify hypothesis based on direct observations.
5) If consistent, develop and implement treatment addressing the function.
6) If inconsistent, conduct further assessments.
7) If needed, conduct functional analysis to confirm hypothesis or resolve inconsistencies.
Chapter 14: Applying extinction
Extinction + nonaversive functional treatments: extinction, differential reinforcement, and antecedent manipulations (functional basis).
Extinction variations depend on the maintaining reinforcement (social vs automatic; positive vs negative reinforcement).
Using extinction to decrease problem behavior: 1) Collect data to assess treatment effects. 2) Conduct a functional assessment to identify the reinforcer for the problem behavior. 3) Eliminate the reinforcer for the problem behavior.
Important considerations: identify the reinforcer; can you eliminate it? is it safe? can you tolerate an extinction burst? can you be consistent?
4) Consider the prior reinforcement schedule (CRF extinction is faster than PRF extinction).
5) Use differential reinforcement to reinforce an alternative behavior.
6) Promote generalization/maintenance: extinction in all relevant circumstances; maintain extinction over time.
Chapter 15: Differential reinforcement
Types of differential reinforcement (DR): DRA, DRO, DRL.
DRA (Differential reinforcement of alternative behavior):
Reinforcer is delivered for desirable behavior; extinction for problem behavior.
Examples: table manners; punching ATM code appropriately, passing the correct items; sharing to replace fighting.
When to use DRA:
To increase desirable behavior and/or decrease undesirable behaviors.
Desirable behavior already occurs occasionally.
A reinforcer is available.
Using DRA (steps):
1) Define desirable behavior to increase; define undesirable competing behavior to decrease.
2) Identify reinforcer for desirable behavior; consider using Premack principle and preference assessments; consider establishing operations (EOs).
3) Reinforce desirable behavior immediately and consistently; ensure the behavior requires less effort than the problem behavior; reduce reinforcement for undesirable behavior.
4) Use intermittent reinforcement for maintenance; promote generalization.DNRA (Differential Negative Reinforcement of Alternative behavior): desirable behavior provides escape/avoidance of aversive stimulus; undesired behavior does not.
Variants: DRI (Differential reinforcement of incompatible behavior); DRC (Differential reinforcement of communication).
DRO (Differential reinforcement of other behavior): reinforce the absence of the problem behavior; extinction for the problem behavior; intervals defined per baseline; if problem occurs, interval resets. Endpoints: whole-interval DRO vs. momentary DRO; whole-interval generally more effective; maintained maintenance.
DRL (Differential reinforcement of low rates of responding): reduce occurrence rate without eliminating; two types:
Full-session DRL: reinforcement for fewer than a threshold in a session; timing not critical.
Spaced-responding DRL: reinforcement for responses separated by a minimum IRT; timing matters; interval DRL uses average time between responses.
DRL examples provided (smoking fewer than 5 cigarettes; fewer table interruptions; class answering with 10-minute gaps; 15-second rule for biting).
Chapter 16: Antecedent control procedures
Antecedent control procedures (also called antecedent manipulations, stimulus control, situational inducement):
Based on functional assessment information.
One of three functional, nonaversive treatments (alongside extinction and differential reinforcement).
Involve altering the environment before the target behavior occurs; address antecedents rather than consequences (though consequences may be indirectly affected via MOs).
Used to increase desirable behavior and decrease undesirable competing behaviors; used with differential reinforcement.
Procedures to increase desirable behavior:
Present SD or cues for desirable behavior (stimulus control): SD presence increases the likelihood of the behavior; cues/reminders help.
Arrange MOs (EOs) to make the reinforcer more potent.
Decrease response effort for desirable behavior (easier to perform than competing behaviors).
Procedures to decrease competing (undesirable) behaviors:
Remove SDs or cues for competing behaviors.
Arrange abolishing operations (AOs) for competing behaviors to reduce reinforcer potency.
Increase response effort for competing behaviors (more effort makes competing behaviors less likely).
Practical considerations:
Identify relevant antecedents via a functional three-term analysis.
Determine which SDs/MOs can be altered.
Assess whether altering antecedents is feasible and acceptable.
Chapter 17: Using punishment: Time-out and response cost
When to use punishment procedures:
Only after trying functional nonaversive procedures (extinction, DRA, and antecedent manipulations).
Controversial due to ethical concerns; aversive vs nonaversive.
Time-out (punishment by withdrawal from reinforcement):
Brief loss of access to positive reinforcers contingent on problem behavior; aim to decrease future probability.
Types: exclusionary (removed from reinforcers and situation) and nonexclusionary (removed from reinforcers but not the situation).
Guidelines:
Start with functional/nonaversive treatments; ensure time-in environment is reinforcing; reinforce desirable behavior; respond to problem behavior immediately by moving to time-out; time-out should be brief, safe, and not allow escape; no attention during time-out; calmness before release; extend time-out if problem persists; ensure acceptability with caregivers.
Response cost:
Removal of a specified amount of a reinforcer contingent on the problem behavior; aim to decrease future probability.
Examples: fines, loss of privileges.
Implementation steps: identify reinforcer to lose, decide permanence, implement immediately if possible, or symbolically if delayed; ethical considerations; practical and acceptable.
Comparison of extinction, time-out, and response cost:
Extinction: reinforcement is no longer contingent on problem behavior.
Time-out: removal from reinforcement; from the reinforcing environment.
Response cost: loss of a reinforcer contingent on problem behavior (but not removal of the reinforcer for the problem behavior).
Chapter 18: Positive punishment procedures and the ethics of punishment
Types of positive punishment:
Punishment by application of aversive activities (overcorrection):
Positive practice: correct form of the relevant behavior repeatedly after the problem behavior.
Restitution: restore environment to a better condition than before the problem behavior.
Contingent exercise; Guided compliance; Physical restraint (blocking/interrupting the response).
Punishment by application of aversive stimulation (e.g., lemon juice, ice, spray)
Cautions and ethics:
Use aversive procedures only when necessary and as a last resort; ensure the agent is capable; ensure the client does not find the procedure reinforcing; ensure safety.
Informed consent, alternatives, safety, severity, supervision, accountability, and peer review.
Potential problems: emotional reactions, increased aggression, escape/avoidance, modeling of punishment, conditioning a punisher.
Chapter 19: Promoting generalization
Generalization: stimulus generalization, response generalization, maintenance of behavior across contexts.
Strategies to promote generalization:
Reinforce instances of generalization outside training; train skills that contact natural contingencies; modify natural contingencies of reinforcement/punishment; incorporate varied SDs and contexts; teach range of functionally equivalent responses; incorporate self-generated mediators (self-instructions, cues).
Generalization training: use varied contexts and exemplars to promote robust generalization; general case programming; introduce common stimuli (people, environments).
Implement strategies across contexts and measure generalization; plan for maintenance and renewal/spontaneous recovery considerations.
Indicators of successful treatment: reduction in problem behavior, increase in functionally equivalent alternative behaviors, generalization across contexts, and increased reinforcement.
Part 5: Other behavior change procedures
Chapter 20: Self-management
Self-management problems involve behavioral excesses and deficits; governed by short-term contingencies vs long-term consequences.
Self-management: using behavior modification to change one’s own behavior.
Self-management process:
Analyze target and competing behaviors (excess and deficit).
Involves a controlling behavior (self-management strategy) and the controlled behavior (target behavior).
The controlling behavior is used in the present to influence future controlled behavior.
Self-management strategies:
Goal setting and self-monitoring.
Antecedent manipulations (SDs/MOs/response effort).
Behavioral contracting (to be discussed in Chapter 23).
Arranging reinforcers/punishers; be wary of short-circuiting contingencies.
Social support; self-instructions and self-praise (to be discussed in Chapter 25).
Steps in self-management:
1) Commit to the process.
2) Define target and competing behaviors.
3) Set a goal.
4) Develop and implement a self-monitoring plan.
5) Conduct a functional assessment of antecedents/consequences.
6) Implement appropriate self-management strategies.
7) Evaluate change from baseline.
8) Reevaluate and modify strategies as needed.
9) Implement maintenance strategies to sustain changes over time.Common problems in self-management:
Unclear descriptions of antecedents/consequences; vague procedures; impractical or costly procedures; delayed consequences; poor functional assessment; inadequate reinforcement/punishment; non-implementation.
Chapter 21: Habit reversal procedures
Types of habit behaviors: nervous habits (hand-related), motor/vocal tics, stuttering.
Habit reversal components:
Awareness training: identifying occurrences, antecedents.
Competing response training: physically incompatible response; contingent on habit; practice first symbolically, then publicly.
Social support: involved others prompt and praise; DRO for absence and DRA for correct use of competing response.
Motivation strategies: review inconveniences of the habit.
Examples of competing responses:
Nervous habits: hold fist at side, place hand in pocket, hold something, etc.
Bruxism: keep teeth apart or lightly clench.
Motor tics: tense involved muscles; vocal tics: slow, deep breathing.
Stuttering: regulated breathing strategies.
Implementation: typically in sessions with daily life practice; motivation is crucial; can be combined with self-monitoring and goal setting.
Effectiveness considerations: awareness and competing response may function as punisher; awareness alone can be effective; sometimes combined with self-monitoring.
Other treatments for habit behaviors when reversal is less effective: awareness enhancement devices, response prevention, blocking, DRO, DRO with response cost, self-administered punishers, CBT.
Chapter 22: The token economy
Token economy = system of points/tokens that are conditioned reinforcers; tokens can be exchanged for backup reinforcers.
Used to increase desirable behaviors in educational or treatment settings; can be used with response costs.
Examples: classroom tokens; hospital/military settings; group homes; prisons; juvenile programs.
Implementing a token economy:
1) Identify target/desirable behaviors (and undesirable ones if needed).
2) Choose tokens (easy to deliver and accumulate).
3) Identify and procure backup reinforcers.
4) Decide on token delivery schedule.
5) Set token exchange rate.
6) Define time/place for exchanging tokens (token store).
7) Consider whether to use response cost.
8) Train staff; monitor progress and implementation.Practical considerations:
Deliver tokens immediately after desirable behavior; pair with descriptive praise; early on pair tokens with backup reinforcers.
Fade the token system before the client exits the program.
Prevent token theft/counterfeiting; ensure basic rights are not compromised.
Advantages and disadvantages:
Advantages: immediate reinforcement, structured, tokens work across various MOs, easy to quantify, allows for response cost.
Disadvantages: time/effort to implement, cost of backups, staff training/management.
Chapter 23: Behavioral contracts
Behavioral contracts (contingency/performance contracts):
Written agreement between two parties identifying a specific target behavior and consequences.
Components:
1) Target behavior and criterion level (goal setting).
2) How behavior will be measured.
3) When the behavior must occur (time frame).
4) Contingencies (reinforcement/punishment).
5) Who will implement contingencies (contract manager or others).
6) Signatures (public commitment).Types:
One-party (unilateral) contract: typically one party desires change; contractee identifies behavior and signs.
Two-party (bilateral) contract: two parties desire change; sub-types include parallel contracts and quid pro quo contracts.
Negotiation considerations:
For one-party: attain an attainable target and meaningful consequence.
For two-party: more complex due to potential conflicts; professionals may need to negotiate.
Why contracts work: consequences, public commitments, rule-governed behavior; cues, and EO effects.
Applications: weight loss, exercise, studying/academic performance, couples and family therapy.
Chapter 24: Fear and anxiety reduction procedures
Fear and anxiety definitions:
Fear combines operant (escape/avoidance) and respondent behaviors (physiological arousal).
Anxiety is an EO for escape behavior.
Examples: fear of dogs – operant escape/avoidance; autonomic arousal (heart rate, etc.).
Types of anxiety disorders: specific phobia, agoraphobia, social phobia, generalized anxiety disorder, OCD, PTSD, acute stress disorder.
Procedures to reduce fear/anxiety:
Relaxation training: muscle tension reduction, relaxed breathing, attention focusing.
Types of relaxation:
Progressive muscle relaxation (PMR).
Diaphragmatic (deep) breathing.
Attention focusing, guided imagery, hypnosis, meditation.
Behavioral relaxation training (similar to PMR).
Systematic desensitization (Wolpe, 1958): reciprocal inhibition; replace anxiety with relaxation via a fear hierarchy; progress via imagined exposure while maintaining relaxation; generalization to real fear situations.
In vivo desensitization: approach feared stimulus while staying relaxed; reinforcement for each approach; variations include contact desensitization, participant modeling.
Flooding: full-intensity exposure until fear subsides; based on respondent extinction.
Modeling: observe others engage with feared stimulus; live or video.
Chapter 25: Cognitive behavior modification
Defining cognitive behavior: verbal (self-talk) or imaginal behavior; covert; recorded/modified like overt behavior).
Problem of circular reasoning: labeling a behavior is not explaining its cause; causes lie in the environment.
Cognitive behavior in clinical problems:
Behavioral excesses: depression, obsessions/ruminations, fears/phobias, worries.
Behavioral deficits: impulsivity, poor problem solving, self-efficacy/self-confidence.
Functions of cognitive behavior:
A thought or image can function as a CS (e.g., anxiety, anger, arousal).
An SD for other operant behavior (self-instructions, problem-solving, decision-making).
A MO (imaging a positive outcome).
A reinforcer or punisher (self-praise, self-criticism).
Types of cognitive behavior modification:
Cognitive restructuring: remove distressing thoughts or replace with rational/functional thoughts.
Steps:
1) Identify distressing thoughts and contexts.
2) Identify emotional response and problem behavior following thoughts.
3) Help client stop distressing thoughts or replace with rational thoughts.Variations: rational-emotive therapy; systematic rational restructuring; cognitive therapy (Beck): evaluate evidence, alternatives, implications.
Common distortions: all-or-nothing thinking, overgeneralization, disqualifying positives, jumping to conclusions, magnification/minimization, labeling, personalization.
Cognitive coping skills training: for deficits; teach new self-statements to promote desirable behaviors.
Self-instructional training (SIT): identify problem/situation; write self-instructions; use BST to teach; perform self-instructions; apply in problem situations.
Stages of learning SIT via BST: therapist reads aloud; client reads aloud; progress to silent/quiet recitation; co-occur with behavior.
Acceptance-based therapies (newer): alternatives to CBT; Acceptance and Commitment Therapy (ACT): acknowledge troublesome thoughts but pursue behavior change goals; acceptance of thoughts and feelings while achieving goals.
Summary notes: cognitive-behavioral approaches emphasize changing thoughts/expectancies and self-statements to influence affective and behavioral responses; integrate with behavioral strategies and BST for generalization.
Formulas and key equations used in the notes
Behavior measurement equations:
Rate (frequency-based measure):
where Frequency is the number of occurrences and T is the observation time period.Percentage of time performed:
where Duration is total time the behavior was exhibited during the observation period T.
Interobserver agreement (IOA) (frequency/duration):
For two observers measuring frequency or duration:
For interval/time-sampling methods: IOA = rac{ ext{Number of intervals with agreement}}{ ext{Total number of intervals}}.
For frequency within-interval recording: IOA is calculated as percent agreement within each interval, then averaged across intervals.
Three-term contingency core concepts (ABC):
Antecedent (A) → Behavior (B) → Consequence (C) with functionally defined relations (e.g., SD, SΔ, SR, SP).
Notation for reinforcement/punishment relationships:
SR = consequence that strengthens the response.
SP = consequence that weakens (punishment).
SR+/SR− = reinforcement (positive/negative) outcomes.
SP+/SP− = punishment (positive/negative) outcomes.
Common abbreviations:
CRF = Continuous Reinforcement
PRF = Partial (Intermittent) Reinforcement
FR = Fixed Ratio; VR = Variable Ratio
FI = Fixed Interval; VI = Variable Interval
ATD = Alternating-Treatments Design
IOA = Interobserver Agreement
MO = Motivating Operation
EO = Establishing Operation; AO = Abolishing Operation
SD = Discriminative Stimulus; SΔ = S-delta
DFA = Differential Reinforcement of Alternative Behavior (DRA)
DRO = Differential Reinforcement of Other Behavior
DRL = Differential Reinforcement of Low Rates
Key ethical and practical reminders:
Punishment should be last resort after functional nonaversive options fail.
Ensure safety, informed consent, and ongoing monitoring.
Consideration of generalization and maintenance from the outset of treatment.
