Final answer:
The mechanism with no role in Skinner's operant conditioning is genetics. Skinner's behaviorism focused on learning through reinforcements and punishments, not genetic inheritance.
Step-by-step explanation:
The mechanism that has no role in Skinner's approach to behavior is d) Genetics. B.F. Skinner was a psychologist known for his work in behaviorism, specifically operant conditioning. Operant conditioning is a form of learning where behavior is shaped by reinforcements and punishments that follow the behavior. In Skinner's perspective, behaviors are motivated by the consequences received for the behavior - that is, the reinforcements or punishments that follow.
Skinner's approach focuses on learned behaviors rather than genetic factors. Reinforcement, punishment, and extinction are all concepts within this theoretical framework that explain how behavior is learned or unlearned based on the consequences of the behavior. In contrast, genetics, which can determine individual's predispositions and traits, have no role in operant conditioning according to Skinner's view. Instead, operant conditioning is purely about the environmental impacts on behavior.
