Listening and understanding.

The activities involved in mediating reinforcement for a speaker's behavior constitute only one phase of a listener's reaction to verbal stimulation. Other phases include listening and understanding what a speaker has said. It is argued that the relative subtlety of these activities is reason for their careful scrutiny, not their complete neglect. Listening is conceptualized as a functional relation obtaining between the responding of an organism and the stimulating of an object. A current instance of listening is regarded as a point in the evolution of similar instances, whereby one's history of perceptual activity may be regarded as existing in one's current interbehavior. Understanding reactions are similarly analyzed; however, they are considerably more complex than listening reactions due to the preponderance of implicit responding involved in reactions of this type. Implicit responding occurs by way of substitute stimulation, and an analysis of the serviceability of verbal stimuli in this regard is made. Understanding is conceptualized as seeing, hearing, or otherwise reacting to actual things in the presence of their "names" alone. The value of an inferential analysis of listening and understanding is also discussed, with the conclusion that unless some attempt is made to elaborate on the nature and operation of these activities, the more apparent reinforcement mediational activities of a listener are merely asserted without an explanation for their occurrence.
