Concept:Thorndike’s primary laws of learning are readiness, exercise, and effect. The law of effect is fundamental because it uses satisfaction and reinforcement to strengthen learning.
Explanation:Thorndike, an American psychologist, proposed the trial and error theory of learning.
He identified three primary laws: law of readiness (learner’s eagerness), law of exercise (practice and repetition), and law of effect (motivation and reinforcement).
The law of effect states that behaviors followed by pleasant consequences are more likely to be repeated, while unpleasant consequences weaken them.
This law is central to learning because it explains how rewards and satisfaction shape behavior.
The other options – law of attitude, law of analogy, and law of associative shifting – are supplementary or minor laws of learning, not primary ones.
Hence, law of effect is the correct choice.
Answer:B. Law of effect
