今天我们要跟同学分享的是TPO30听力部分的lecture 1，一个关于心理学话题的演讲。文章主要是探讨动物的认知能力，通过两个关于动物的实验得出相应的结论。在听力中要对实验非常留意，实验在听力中是一个常见的考点，信号词有：study, experiment, finding, research。实验除了要听实验内容以外，更重要的是实验目的，实验目的的信号词有：suggest, tell, indicate, indicator, present, illustrate, illustration, explain, explanation, show, mean, meaning, prove, propose,evidence.
来看具体题目：
5.What can be inferred from the results of the study in which monkeys did not receive immediate feedback? D
A.The research based the study on an incorrect hypothesis.
B.Monkeys respond best to negative reinforcement.
C.Monkeys become confused when they do not receive rewards.
D.Monkeys probably have some degree of metacognitive ability.
这是一道考实验目的的推断题，定位到对实验总结性的描述：
And this is evidence that it wasn’t a conditioned response, because that responsedidn’tguarantee a faster reward. 猴子的反应并不仅仅是conditioned response (条件反射)，所以这个实验说明猴子也许可以感觉到不确定性。
