B.20 · Multiple control in verbal behavior
Why does a hungry kid looking at cookies say "Cookie!"? Is it a mand or a tact? The honest answer is "both," and that answer is what multiple control is about.
Key takeaway
Most verbal responses are controlled by more than one variable at once, so pure mands or pure tacts are rare. Convergent multiple control means many variables strengthen one response. Divergent multiple control means one variable strengthens many responses. Prompts work by adding convergent control, and fading them shifts control to the target variable alone.
