Behavior

Any action a person performs that can be observed, described, and measured by others. Behavior is the primary focus of assessment and intervention in applied behavior analysis.

Related: Three-term contingency, Operational definition
Three-term contingency

The arrangement of an antecedent event, the behavior that follows it, and the consequence that follows the behavior. It explains why a behavior occurs and what keeps it going.

Related: Behavior, Reinforcement, Functional behavior assessment
Reinforcement

A consequence delivered after a behavior that increases the likelihood the behavior will happen again in similar situations. It can involve adding a preferred stimulus or removing an unpleasant one.

Related: Three-term contingency, Extinction, Differential reinforcement of alternative behavior
Social validity

The extent to which the goals, procedures, and outcomes of an intervention are acceptable, meaningful, and important to the client, caregivers, and other stakeholders.

Related: Family-centered approach, Caregiver training
Informed consent

Agreement to take part in assessment or treatment given by a person who understands the purpose, procedures, risks, benefits, and alternatives, and who agrees voluntarily without pressure.

Related: Confidentiality, Scope of competence
Confidentiality

The ethical duty to protect client information from unauthorized disclosure, sharing it only with people who have a legitimate need and a legal right to know.

Related: Informed consent, Mandated reporting
Multiple relationships

A situation in which a behavior analyst holds another personal, financial, or professional relationship with a client or supervisee that could cloud judgment or harm the client.

Related: Confidentiality, Scope of competence
Scope of competence

The boundaries of a practitioner's education, training, and supervised experience. Services should be delivered only within these limits, with referral or extra training when a case falls outside them.

Related: Informed consent, Supervision contract
Mandated reporting

The legal duty of certain professionals to report suspected child abuse, neglect, or other serious harm to designated authorities, even when the information would normally stay confidential.

Related: Confidentiality, Interdisciplinary team
Operational definition

A written description of a behavior that is observable and measurable, and precise enough that different observers agree on when the behavior occurs and when it does not.

Related: Interobserver agreement, Baseline
Baseline

The phase of data collection before intervention begins, used to describe the current level of the behavior and to provide a comparison for later changes.

Related: Operational definition, Frequency
Frequency

A count of how many times a behavior occurs during a set observation period. It works best when the behavior has a clear beginning and end.

Related: Duration, Partial interval recording
Duration

The amount of time a behavior lasts, measured from its start to its end. It is used when the length of the behavior matters more than how often it happens.

Related: Frequency, Momentary time sampling
Partial interval recording

A time-sampling method in which the observer records whether a behavior occurred at any point during a short interval. It tends to overestimate brief or sporadic behavior.

Related: Momentary time sampling, Duration
Momentary time sampling

A time-sampling method in which the observer records whether the behavior is occurring at the exact moment each interval ends, rather than at any time during the interval.

Related: Partial interval recording, Frequency
Functional behavior assessment

A process of gathering information to identify the antecedents and consequences that maintain a problem behavior, using indirect methods, direct observation, and sometimes an experimental analysis.

Related: Three-term contingency, Preference assessment
Preference assessment

A structured procedure used to identify stimuli or activities a client is likely to work for, often by observing choices among items or by asking caregivers and the client.

Related: Reinforcement, Functional behavior assessment
Interobserver agreement

The degree to which two or more independent observers record the same behavior in the same way, usually reported as a percentage of agreement between their records.

Related: Operational definition, Treatment integrity
Treatment integrity

The extent to which an intervention is carried out as written and intended, including correct use of the procedures, materials, and schedule across sessions and staff members.

Related: Performance feedback, Interobserver agreement
Task analysis

Breaking a complex skill into smaller, teachable steps that are ordered in the sequence needed for the learner to complete the whole skill.

Related: Chaining, Prompt
Chaining

Teaching a task analysis one step at a time and linking the steps together until the learner completes the whole sequence. Forward and backward versions differ in where teaching starts.

Related: Task analysis, Prompt fading
Prompt

An added cue, instruction, model, or physical guidance given with or just before a learning opportunity to help the learner perform the target response correctly.

Related: Prompt fading, Discrimination training
Prompt fading

Gradually reducing the amount or intensity of prompts across teaching trials so the learner responds to the natural cue instead of depending on adult assistance.

Related: Prompt, Generalization
Discrimination training

Teaching a learner to respond differently to one stimulus than to another, for example responding when their own name is called but not when a different name is called.

Related: Prompt, Generalization
Generalization

The occurrence of a learned skill in settings, with people, or with materials different from those used during teaching, or in response to similar but untrained instructions.

Related: Maintenance, Discrimination training
Maintenance

The continuation of a learned skill after teaching has ended, often checked through follow-up probes conducted weeks or months after the final training session.

Related: Generalization
Discrete trial teaching

A structured teaching method in which the instructor gives a brief instruction, the learner responds, and the instructor delivers a consequence before a short pause and the next trial.

Related: Prompt fading, Naturalistic teaching
Naturalistic teaching

Teaching during everyday routines and play, using items and activities the learner is motivated for so that learning opportunities fit naturally into ongoing activities.

Related: Discrete trial teaching, Generalization
Functional communication training

Teaching a learner a clear, acceptable way to ask for something they want or need, such as a sign or picture, so that problem behavior is no longer needed to get it.

Related: Differential reinforcement of alternative behavior, Extinction
Differential reinforcement of alternative behavior

Reinforcing a specific appropriate behavior while withholding reinforcement for the problem behavior, so the appropriate response becomes more likely over time.

Related: Functional communication training, Extinction
Extinction

Discontinuing the reinforcement that previously maintained a behavior. This typically produces a temporary increase in the behavior before the behavior gradually decreases.

Related: Differential reinforcement of alternative behavior, Functional behavior assessment
Behavioral skills training

A training package that teaches staff or caregivers through instruction, modeling, rehearsal, and feedback until they perform the target skill correctly and without assistance.

Related: Performance feedback, Competency-based training
Performance feedback

Specific information given to a trainee about how well they performed a skill, usually pairing praise for correct steps with a clear description of what to change next time.

Related: Behavioral skills training, Treatment integrity
Competency-based training

Training that requires trainees to demonstrate a skill to a defined standard before moving on, rather than only attending a session or passing a written test.

Related: Behavioral skills training, Supervision contract
Supervision contract

A written agreement between supervisor and supervisee describing goals, roles, meeting schedule, evaluation methods, and expectations for the supervisory relationship.

Related: Competency-based training, Scope of competence
Pyramidal training

A model in which an expert trains a small group of staff, who then train others, allowing skills to spread through an organization efficiently.

Related: Behavioral skills training, Performance feedback
Interdisciplinary team

A group of professionals from different fields, such as speech therapy, occupational therapy, and education, who share information and coordinate goals for a client.

Related: Coordination of care, Family-centered approach
Family-centered approach

Practice that treats caregivers as partners, respects their priorities and culture, and builds intervention goals around the family's values and daily routines.

Related: Caregiver training, Social validity
Caregiver training

Teaching parents or other caregivers to deliver interventions and collect data, using the same instruction, modeling, practice, and feedback methods used with staff.

Related: Behavioral skills training, Family-centered approach
Coordination of care

Sharing relevant information and aligning goals, schedules, and strategies with other providers so that services support one another instead of working at cross purposes.
