Final answer:
Choice 'd' ('I can answer this math problem.') is the correct example of an assertive autoclitic indicating the response as an intraverbal, as it shows the speaker's confidence in their ability to solve a math problem, presumably in response to a discussion or question.
Step-by-step explanation:
The term assertive autoclitic refers to verbal behavior that modifies the listener's response to a statement by indicating the speaker's confidence or commitment to what they are saying. In the context of behavior analysis, an autoclitic is a secondary verbal behavior that modifies the form and/or function of primary verbal behaviors like mands, tacts, and intraverbals. In the examples provided, choice "d" ('I can answer this math problem.') is the one that is most clearly an assertive autoclitic as it indicates the response is emitted as an intraverbal. An intraverbal is a type of verbal behavior where the speaker responds to another's verbal behavior with language that is not directly related to a stimulus such as a question or comment from another person.
Here, 'I can answer this math problem' shows the speaker's assertion that they are able to perform the task of solving a math problem, suggesting a response to a prior question or statement about a math problem. The assertiveness of the autoclitic lies in the speaker's confidence indicated by 'I can' which modifies any listener's interpretation of the ability of the speaker to answer the math problem.
