19、0 seconds response time:60 seconds24整理笔记，最终开口整理笔记，最终开口T(according to the reading):audience effects affected if they know being watchedExample 1:tying shoes,1 group knew,type faster,1 not.Example 2:learning to type faster,but mistakes25The principle of audience effects is that individuals performance

20、 is affected by the knowledge that others are watching them.The professor uses examples of tying shoes and learning to type to demonstrate that we actually increase our speed of performing if we know that we are being observed.In the example of tying shoes,one group of college students was told that

21、 they were being observed,the other didnt know they were being observed.The students who knew they were being watched tied their shoes much faster than the other group.And in the example of learning to type,when we are conscious of being observed,we will increase typing speed.We type faster than we

22、do alone.Also,other behavioral pattern will increase,like making mistakes.So when we type faster when we know we are being observed,we also make more mistakes.示范回答示范回答26Sample answer 1In this lecture,the professor gives two examples to illustrate the principles of audience effects.One of them is tyi

23、ng shoes,and the other one is how to type.So in the experiment where two groups to tie their shoes,The first group were said they were be observed,The other one was not told so.The first group that they knew they would be observed tied their shoes faster;and the other one slower.In the second exampl

24、e;activities such as learning typing;again when people are conscious they are being observed they type faster.However,they tend to make more mistakes as well.So the suggestion is to practice new activities alone in order to reduce mistakes27Speak clearly and fluently.Show a good command over grammar

25、 and vocabulary.State very clearly and logically the concept and two examples.28Topic 段段:T1 OK,so we said that the way we interact with others has an impact on our behavior.In fact,theres some interesting research to suggest that in one type of interaction-when were being observed specifically,when

26、we know were being watched as we perform some activity-we tend to increase the speed at which we perform that activity.29分组：标准？分组：标准？Reason段：段：R1In one study,college students were asked to each put on a pair of shoes-shoes with laces they would have to tie.Now one group of students was told that the

27、y would be observed.The second group,however,didnt know they were being observed.The students who were aware that they were being watched actually tied their shoes much faster than the students who thought they were alone.Other studies confirm the same is true even when were learning new activities.

28、差别：特征？差别：特征？30Lets say someone is learning a new task-for example,learning how to type.When theyre conscious of being observed,theyll likely begin typing at a much faster rate than they would if they were alone.But,and this is interesting,the study also showed that certain common behavior-things peo

29、ple typically do,like.making mistakes when youre learning something new that behavior pattern will also increase.So in other words,when were learning to type,and we know were being watched,well type faster but well also make more mistakes.Reason段：段：R231HomeworkSampling errorOften,students or employe

30、es will be asked to draw a conclusion from a huge amount of data.Thats when a sample is introduced.When a sample is accurate,it can represent the whole group.But when it is wrong,sampling error would occur.In statistics,sampling error or estimation error is caused by observing a single sample instea

31、d of the whole population.Sampling error can be found by subtracting the value of a parameter from the value of a statistic.Generally,there are two methods of reducing sampling error:increasing the sample size,and ensuring that the sample can adequately represent the entire population.32Narrator Now

32、 listen to a lecture on this topic in a statistics class.3334When the dialogue ended,the picture of the students will be replaced by the following:Now get ready to answer the question.35The question will then appear on your computer screen and will also read by the narrator.The professor uses one experiment to illustrate the definition of sampling error.Explain how this example is related to the reading passage.prepare time:30 seconds response time:60 seconds3637
