Answer:
c) Modifying contingencies of reinforcement and punishment in the natural environment.
Step-by-step explanation:
According to a different source, these are the options that come with this question:
a) Reinforcing occurrences of generalization.
b) Training skills that contact natural contingencies of reinforcement.
c) Modifying contingencies of reinforcement and punishment in the natural environment.
d) Incorporating a wide range of relevant stimulus situations in training.
Contingencies of reinforcement are antecedents (events that occur immediately before a behaviour) and consequences (occur after a behaviour). In particular, contingencies refer to the relationships between these situations, while reinforcement refers to consequences that increase the probability of the behaviour occurring again. In this example, by modifying the contingencies of reinforcement and punishment, Joel is allowing parents to practice, thus ensuring that generalization is promoted.
