One of the most widespread and important types of learning is operant conditioning, which involves increasing a behavior by following it with a reward, or decreasing a behavior by following it with punishment. For example, if a mother gives a boy his favorite snack every day for his cleaning up his room, before long the boy may spend some time each day cleaning his room in anticipation of the snack. In this example, the boy’s room-cleaning behavior increases because it is followed by a reward.
Unlike classical conditioning, in which the conditioned and unconditioned stimuli are presented regardless of what the learner does, operant conditioning requires action on the part of the learner. The boy in the above example will not get his snack unless he first cleans up his room. The term operant conditioning refers to the fact that the learner must operate, or perform a certain behavior, before receiving a reward or punishment.
Some of the earliest scientific research on operant conditioning was conducted by American psychologist Edward L. Thorndike at the end of the 19th century. Thorndike’s research subjects included cars, dogs, and chickens. To see how animals learn new behaviors. Thorndike used a small chamber that he called a puzzle box. He would place an animal in the puzzle box, and if it performed the correct response (such as pulling a rope, pressing a lever, or stepping on a platform), the door would swing open and the animal would be rewarded with some food located just outside the cage. The first time an animal entered the puzzle box. It usually took a long time to make the appropriate response required to open the door. Eventually, however, it would make the appropriate response by accident and receive its reward: escape and food. As Thorndike placed the same animal in the puzzle box again and again, it would make the correct response more and more quickly. Soon it would take the animal just a few seconds to earn its reward.
Based on these experiments, Thorndike developed a principle he called the law of effect. This law states that behaviors that are followed by pleasant consequences will be strengthened, and will be more likely to occur in the future. Conversely, behaviors that are followed by unpleasant consequences will be weakened, and will be less likely to be repeated in the future, Thorndike’s law of effect is another way of describing what modern psychologists now call operant conditioning.

第1题:
【选项释义】
The difference between classical conditioning and operant conditioning is that _____. 经典条件反射和操作性条件反射的区别是_____。
A. the former emphasizes punishment, while the latter emphasizes the operation A. 前者强调惩罚,后者强调操作
B. the former emphasizes reward, while the latter emphasizes the operation B. 前者强调奖励,后者强调操作
C. the former emphasizes stimulus, while the latter emphasizes the operation C. 前者强调刺激,后者强调操作
D. the former emphasizes snack, while the latter emphasizes the operation D. 前者强调零食,后者强调操作
【考查点】推理判断题。
【解题思路】由文章第二段中的第一句“在经典的条件反射(classical conditioning)中,无论学习者做什么,都会呈现条件性和非条件性刺激(stimuli)”以及最后一句“操作条件(operant conditioning)一词是指学习者在得到奖励或惩罚之前必须操作(operate)或进行某种行为的事实”,由此可知经典条件强调刺激,操作条件强调操作,因此选C。
【干扰项排除】
A、B、D选项不符合原文,属于曲解原文。
第2题:
【选项释义】
What’s the occupation of Edward L. Thorndike? 爱德华•L•桑代克的职业是什么?
A. A teacher. A. 老师。
B. A scientist. B. 科学家。
C. A learner. C. 学者。
D. An engineer. D. 工程师。
【考查点】事实细节题。
【解题思路】根据题干定位到文章第三段第一句“19世纪末,美国心理学家Edward L. Thorndike对操作条件进行了最早的科学研究”可知Edward L. Thorndike是一名心理学家,心理学属于科学范畴,因此选B。
【干扰项排除】
A、C、D选项不正确,属于曲解原文。
第3题:
【选项释义】
Why could the animals in the puzzle box gibe correct response more and more quickly? 为什么谜盒中的动物能越来越快地做出正确的反应?
A. Because they had been forced to so. A. 因为他们被迫这样做。
B. Because they had been rewarded many times after being able to do so. B. 因为他们能够这样做之后,已经得到了很多次的奖励。
C. Because they understood that people were doing an experiment on them. C. 因为他们知道人们在他们身上做实验。
D. Because they were the cleverest animals. D. 因为它们是最聪明的动物。
【考查点】推理判断题。
【解题思路】通过文章第三段中Edward L. Thorndike的实验,可知动物第一次打开这个门需要很长时间,随着多次的反复的操作,打开门所用时间逐渐减少,形成了条件反射,因此选B。
【干扰项排除】
A、C、D选项原文没有提及,属于无中生有。
第4题:
【选项释义】
Which of the following may be inferred according to the law of effect? 根据效果定律,下列哪项可以推断?
A. Behaviors will be strengthened, if they are followed by pleasant consequences. A. 如果行为能带来愉快的结果,它就会得到强化。
B. Behaviors will be weakened, if they are followed by unpleasant consequences. B. 如果随之而来的是不愉快的后果,行为就会被削弱。
C. Behaviors will not be repeated, if they are followed by punishment. C. 如果采取惩罚措施,行为将不会再发生。
D. Teachers should praise and encourage students more. D. 老师应该多表扬和鼓励学生。
【考查点】推理判断题。
【解题思路】由文章最后一段可知“the law of effect效应定律”指的是下文“这条定律规定,伴随着愉快后果的行为将得到加强,并且在未来更有可能发生。相反,伴随着不愉快后果的行为将被削弱,并且在未来不太可能被重复”。由此可以推断出D选项。
【干扰项排除】
A、B选项属于事实,不属于推断内容;
C选项“如果采取惩罚措施,行为将不会再发生”,与最后一段第三句“如果再加上惩罚,行为就会被削弱(weakened)”不符,属于曲解原文。
第5题:
【选项释义】
The phrase “swing open” (Line 6. Para. 3) means _____. 短语“swing open”(第六行,第3段)的意思是_____。
A. turn open A. 转开
B. move open B. 移开
C. push open C. 推开
D. pull open D. 拉开
【考查点】词义推测题。
【解题思路】定位到第三段第五句“他会把一只动物放进谜盒中(in the puzzle box),如果它做出正确的反应(如拉绳子、按杠杆或踩平台),门就会……,动物就会得到笼子外(outside the cage)的一些食物作为奖励”,结合下文“笼子外”可知,上文应该是强调“门会打开”,选项A符合。
【干扰项排除】
B、C、D选项不符合词义,属于曲解原文。
