an observable stimulus accompanies a private event (see a child get stung by a bee and inferring a painful stimulus, listener reinforces tact “ouch!”)
an observable response accompanies a private stimuli (seeing a child crying and rubbing their arm. didn’t see the bee sting, but the behavior suggests a painful stimulus is present)
speaker uses metaphorical extension of a public stimulus to tact a private stimulus (my head is foggy)
speakers learn to tact movements and positions of their bodies (i’m doing a math problem when solving on paper), covert stimuli may be sufficiently similar to generalize (i’m doing a math problem while doing in their head)
convergent multiple control
one response might be the function of several variables (part mand/part tact: the floor is dirty, you see the vacuum, and say “vacuum please)
divergent multiple control
see a car going fast, say “they’re speeding” or “that car is flying” or “look at that car” etc.
verbal behavior that modifies the effect of other verbal behavior on the listener –
Primary – mands, tacts, intraverbals evoked by Sd’s and MO’s
Secondary – speaker comments on the strength or nature of the variables controlling the primary verbal behavior.
Examples – might be, definitely, possibly, very, tells if the stimulus is strong or weak
