"Jump," as a verbal operant, could be:

a tact if the response was emitted upon hearing " jump " This would be a tact for others 's verbal behavior

a tact if the response was emitted upon seeing somebody jumping rope . However, this could also a mand, if an EO was present for the listener to jump rope

a mand because the topography of this response is consistent with a typical mand

Neither a tact or a mand
