Final answer:
In the escape condition of a functional analysis, a learner receives a break from demands as negative reinforcement contingent upon displaying aberrant behavior, thus most likely increasing the occurrence of that behavior.
Step-by-step explanation:
A learner being provided with a break from demands contingent upon displaying aberrant behavior would most likely occur in the escape condition of a functional analysis. This condition is part of operant conditioning, a concept developed by B.F. Skinner, where a behavior is followed by a consequence to either strengthen or weaken it. In the escape condition, the reinforcement provided (in this case, a break from demands) is contingent on the display of the target behavior, which in this scenario is presumed to be aberrant.
Operant conditioning also includes a punishment condition, but in the context of this question, providing a break would act as negative reinforcement, because it allows the individual to escape from an unpleasant situation, hence reinforcing the aberrant behavior. In contrast, punishment would be utilized to decrease the likelihood of the behavior occurring again. Considering the four options given, the escape condition aligns with the scenario presented.
