THE TACT • VERBAL BEHAVIOR UNDER CONTROL OF DISCRIMINATIVE STIMULI: THE PRESENCE OF AN OBJECT OR EVENT INCREASES THE PROBABILITY OF A VERBAL RESPONSE OF A GIVEN FORM. In the presence of a cat, we are more likely to say “cat.” But what about “self tacting”? How do we come to talk about feeling states, memories, etc. VERBAL BEHAVIOR and PRIVATE EVENTS THE “PROBLEM” OF CONSCIOUSNESS AND A SELFDESCRIPTIVE REPERTOIRE. “…IT IS THE COMMUNITY THAT TEACHES THE INDIVIDUAL TO ‘KNOW HIMSELF’” HOW DO WE DEAL WITH PRIVATE EVENTS? • Assumption: The private world is not made of different “stuff.” • But there are two problems for a scientific account: (1) private events not directly observable, and (2) how does the verbal community establish tacting of such events? THERE ARE AT LEAST FOUR WAYS “My tooth hurts!” 1. 2. 3. 4. Common public accompaniment A collateral response A metaphorical extension A shift in magnitude of the response WHY DOES BEHAVIOR BECOME COVERT? 1. Self-description useful to the listener. 2. Controlling variables may be weak. 3. Magnitude may decrease if still effective for the speaker (as listener). 4. Overt verbal behavior may be punished. 5. Malingering.
