What does the term 'function' refer to in verbal behavior?

In the context of verbal behavior, the term 'function' specifically refers to the consequences that maintain a behavior. This concept stems from the understanding that behaviors are reinforced or discouraged based on their outcomes. For verbal behavior, this means that the effectiveness and frequency of communication are greatly influenced by the consequences that follow those verbalizations. If a particular verbal behavior results in a desired outcome (such as gaining attention, acquiring information, or achieving a specific goal), it is more likely to be repeated in the future. Thus, the function of a behavior encompasses the reason it occurs, defined by its reinforcing properties.

Conversely, the appearance or presentation of behavior, the methods of teaching a behavior, and the process of data collection do not define the function. Those elements are related to behavior analysis and teaching strategies but do not capture the essence of why a specific verbal behavior is maintained or increased, which is the core significance of 'function' in verbal behavior.
