ABSTRACT
In the discriminated verbal-nonverbal level of explanation, the verbal component in the verbal-nonverbal chain could function as an antecedent event to which the corresponding nonverbal behavior could be conditioned. In the intermediated level of explanation, behaviors that occur between a report about future behaviors and the fulfillment of this report could function as antecedent events for the occurrence of the nonverbal behavior. The levels are termed discriminated, generalized-maintained, intermediated, and preceding verbal-nonverbal correspondence levels of explanations. In the level of explanation, behaviors that precede both the verbalization and its corresponding nonverbal behavior may function as antecedent events for subsequent behaviors, in a do-report sequence. Rules involving discriminated verbal-nonverbal correspondences are transformed into generalized and maintained correspondence rules. In the generalized-maintained correspondence level of explanation, a distinction between contingency-governed and rule-governed behavior is often made. A demonstration of verbal-nonverbal relationships during the intervention phase is a case of "contingency-governed behavior".
