01Foundations and Principles of Behavior Analysis
Start with the core definition: behavior is anything a person does that is observable and measurable, described in action terms rather than as a trait ("tore the worksheet" not "was frustrated"). Distinguish response (a single instance) from response class (a set of responses with the same effect on the environment).

Assessment begins with a behavioral definition that is objective, clear, and complete - a stranger should be able to score it reliably. Avoid labels and inferences ("aggressive" is too vague; "closed fist contact with another person's body" is measurable).

A defensible BIP is function-based : it names the target behavior, the hypothesized function (attention, escape, access to tangibles, automatic/sensory), and the replacement behavior that produces the same reinforcer more efficiently. If the plan does not match the function, it usually fails regardless of how well it is written.

Effective supervision is data-based and documented . Begin with a task analysis of the skill to be taught, then use Behavioral Skills Training (BST) : (1) written or verbal instructions, (2) modeling, (3) rehearsal/role-play, and (4) immediate feedback until a mastery criterion is met.

Ethical practice rests on core principles: beneficence (do good), nonmaleficence (do no harm), autonomy (respect client choice), fidelity (be truthful and keep commitments), justice (fair access), and dignity (respect the person). When principles conflict, document your reasoning and prioritize client welfare and safety.
