A single instance of behavior is referred to as what?

A single instance of behavior is referred to as a response. In behavior analysis, a response indicates a specific occurrence of behavior that can be measured and observed. This term is foundational in understanding how behaviors are assessed and analyzed over time.

Responses are distinct and quantifiable actions that occur in reaction to a stimulus. This definition is critical for data collection and the development of behavior modification strategies, as it allows practitioners to track behavior patterns, measure changes over time, and determine the effectiveness of interventions.

The other terms, while related to behavior, describe broader concepts. For instance, 'operant' encompasses a type of behavior that is influenced by its consequences, while 'target behavior' refers to the specific behaviors that an intervention aims to modify. 'Repertoire' describes the collection of skills or behaviors an individual possesses, rather than an individual instance of behavior.
