Answer:
Avoidance learning
Explanation:
Avoidance learning is a process in which a person or animal learns a response to avoid an unpleasant experience. Reinforcement plays a great role in learning where a stimulus avoids an unpleasant stimulus to learn a response.
Thus here in the above statement, Martha pulled for the first time, for her excess speed limit. For this reason, she has to pay a heavy charge. After that, she maintained a consistent speed of up to 40 miles per hour. This behavior indicates her avoidance learning due to previous experience.
