Behavior, Response, Response Class, Stimulus, Stimulus Class
Key Takeaways
- Behavior is an organism's interaction with the environment, not a label for traits, diagnoses, or intent.
- A response is one instance of behavior; a response class is a set of responses that share the same function.
- Stimuli are environmental events or changes; stimulus classes group stimuli by formal, temporal, or functional features.
- Exam items often test whether a term names the behavior, the response instance, the response class, or the controlling stimulus.
Core Units
A behavior is an activity of an organism that can be observed and measured directly or through its effects on the environment. Saying a learner is noncompliant, anxious, or manipulative does not identify behavior. For exam purposes, translate labels into actions: pushing a worksheet away, saying no, leaving the table, or completing one math problem.
A response is one occurrence of behavior. Raising a hand once, saying help once, or pressing a switch once is a response. A response class is a group of responses that share a common effect on the environment, even if they look different. Calling out, tapping a teacher, and handing over a help card may be in the same response class if each reliably produces assistance.
Stimuli and Stimulus Classes
A stimulus is an environmental event, object, condition, or change that can affect behavior. Stimuli may occur before behavior, after behavior, or as part of the broader context. Do not confuse a stimulus with the person's feeling or presumed motive unless the scenario gives observable private-event wording and a behavioral relation.
Stimulus classes group stimuli by shared features. Formal classes share physical properties. Temporal classes occur at the same time or in sequence. Functional classes have the same effect on behavior. A red card, a red light, and red text form a formal class if redness matters. Several different teacher requests form a functional class if each evokes the same response.
Decision Aid
| Term | Exam question to ask | Example |
|---|---|---|
| Response | What happened one time? | Student says break. |
| Response class | What different responses have the same effect? | Says break, gives card, walks to break area. |
| Stimulus | What environmental event is present or changed? | Timer rings. |
| Stimulus class | What stimuli share form, timing, or function? | Several timers signal transition. |
When answer choices include a mentalistic label and an observable unit, choose the observable unit. When choices include topography and function, check the question stem. If it asks what the response looks like, select topography. If it asks why multiple forms belong together, select shared function.
A learner can request help by raising a hand, saying help, or handing over a help card. Each response produces teacher assistance. What is the best classification of these three responses?
During observation, a technician records that the client is aggressive. Which revision best converts the label into behavior?
A green card, a spoken instruction to start, and a chime all occasion beginning independent work after each has been trained. What kind of class do they form in this context?
