Final answer:
The VR-3 Omission Training would be the most resistant to extinction among the given options, due to the unpredictability and effectiveness of the variable ratio reinforcement schedule in maintaining high and steady response rates.
Step-by-step explanation:
The question pertains to which training schedule in operant conditioning would make a behaviour most resistant to extinction. To stamp out a behaviour robustly, making it resistant to extinction, the most effective training schedule would be the variable ratio schedule. Extinction in operant conditioning refers to the decrease in the conditioned response when reinforcement is no longer paired with the behaviour.
Among the options provided, VR-3 Omission Training would likely be the most resistant to extinction. This is due to the unpredictability of the variable ratio schedule, which keeps the response rate high and makes extinction slower. The reinforcement in a variable ratio schedule occurs after a varying number of responses, which is difficult to predict, therefore maintaining the behaviour effectively. In contrast, fixed schedules, whether interval or ratio, are more predictable and lead to quicker extinction once reinforcement stops.
Continuous reinforcement involves rewarding a behaviour every time it occurs, which is effective for initially teaching a new behaviour but not as resistant to extinction. The other schedules mentioned, such as fixed ratio (FR-2 Reward Training) and fixed interval (FR-1 Punishment Training), are not as resistant to extinction as the variable ratio schedule.
