One of the groups is in the highly intelligent and another is in the less intelligent, but the truth of the monkeys are both same, and there is no difference between their intelligence, but the research didn't know about that. One group was considered highly intelligent while the other was considered less intelligent; however, in reality, there was no difference in their intelligence levels, but the researcher was unaware of this fact. (调整了句子结构，使表达更清晰。)

And the less intelligent monkey took two hours less time than the highly intelligent one because the less intelligent suffer more encourage and they felt more enthusiastic than the highly intelligent one. The supposedly less intelligent monkeys took two hours less time to complete the task than the supposedly highly intelligent ones because they received more encouragement and felt more enthusiastic.

Original Answer: The experimentalism is that the researcher's explanation affects the result of the experiment. The experimenter effect occurs when a researcher's expectations influence the outcome of an experiment. (原文中的“experimentalism”应改为“experimenter effect”，并对句子进行相应调整。) In the lecture, the professor took a great example of monkey to illustrate this term. The researcher is given two groups of monkey and they ask him to pick up a boy in the box. The researcher was given two groups of monkeys and was asked to train them to pick up a ball and put it in a box. (原文中的“monkey”应为复数形式“monkeys”，同时修正原文中的错误信息。) And also they record the hours of training. The researcher tells that one group is highly intelligent and the other group is less intelligent. But in truth, they have no big difference between them. And the result is that the so-called intelligent group takes two hours less than the less intelligent group. It's just because that the professor smiled at them and gave them encouragement. And Furman also communicated with them. So actually the professor's behavior affected them.

Revised Answer (140 words):

The experimenter effect occurs when a researcher's expectations influence the outcome of an experiment. In the lecture, the professor provided an example involving monkeys to illustrate this concept. The researcher was given two groups of monkeys and was asked to train them to pick up a ball and put it in a box while recording the hours spent on training. The researcher was informed that one group was highly intelligent, while the other was less intelligent. However, in reality, there was no significant difference between the two groups. The results showed that the supposedly intelligent group took two hours less to complete the task than the less intelligent group. This was because the researcher smiled at them, provided encouragement, and communicated more effectively with the supposedly intelligent group, thus affecting their performance due to his expectations.

The speaker's delivery is generally clear and fluid, but there are some occasional pauses that disrupt the flow. To improve, the speaker should practice speaking more consistently and work on reducing unnecessary pauses. Additionally, focusing on accurate pronunciation will help eliminate any spelling errors that may arise from mispronunciation.

4.Topic Development The response is coherent and well-organized, with clear connections between ideas. However, the speaker could provide more specific details from the lecture to better support their explanation of the experimenter effect. To improve, the speaker should focus on incorporating more examples from the listening passage to further illustrate the concept and strengthen their response.

5.Language Use

The reading passage reading talks about the experimental mental effect experimenter effect. It means when a researcher's expectations could affect the outcome and lead to inaccurate results. For example, there is research an experiment about two groups of monkeys. They were made to pick up the ball and to put up in the box. There are two groups. Actually, the two groups are very similar in intelligence, but the researcher was told the two groups of monkeys are different. One group is highly intelligent and the other group is less intelligent. He expected one group was easy to train.

(I corrected "experimental mental effect" to "experimenter effect" for accuracy, "research" to "an experiment" for clarity, and rephrased some sentences for better flow.)

Revised Answer (140 words):

The reading discusses the experimenter effect, which occurs when a researcher's expectations influence the outcome of an experiment, leading to inaccurate results. In the example provided, an experiment involved two groups of monkeys that were tasked with picking up a ball and placing it in a box. Although both groups had similar intelligence levels, the researcher was falsely informed that one group was highly intelligent while the other was less intelligent. Consequently, the researcher expected that the supposedly smarter group would be easier to train. This expectation affected his behavior during the experiment, as he provided more encouragement and communication to the "intelligent" group than to the other group. As a result, it took less time for him to train the "smart" monkeys compared to their counterparts, illustrating the experimenter effect in action.

Original Answer: The reading passage gives a definition of experimental effect, The reading passage defines the experimenter effect, (修改为更自然的表达方式) which is a phenomenon that the researcher's expectation affects the outcome of the experiment, because the expectation causes the researcher to act in ways that will influence the behavior of the participant and thus invalidate the results. The lecturer uses the example of an experiment when the researcher trained two groups of monkeys to pick a ball and put it in a basket. The researcher was told that one group was more intelligent than the other, and the experiment results come as the same as the supposedly smarter group uses two less hours to be trained However, the fact is, the two groups of monkeys are similar in intelligence, so the result is invalidated. That's because when he was training, the researcher talked a lot more and encouraged a lot more to the smarter monkeys and tried hard, but he didn't try as hard when he trained the other group of monkeys. So that's the example of experimental effect.

Revised Answer (140 words): The reading passage defines the experimenter effect as a phenomenon where a researcher's expectations affect an experiment's outcome because these expectations influence their actions towards participants, ultimately invalidating results. The lecturer illustrates this concept with an experiment involving two monkey groups trained to pick up a ball and place it in a basket. The researcher was informed that one group was more intelligent than the other, leading to faster training for this supposedly smarter group. However, both groups had similar intelligence levels, rendering results invalid. This occurred because the researcher provided more encouragement and effort when training the "smarter" monkeys compared to their counterparts. This example demonstrates how experimenter effect can impact experimental outcomes.

The experimenter effect occurs when a researcher's expectations affect the outcome of an experiment. (将"experimental"改为"experimenter"，更符合原文表述) The professor in the lecture provided an example to demonstrate this concept. In this case, a researcher was given two groups of monkeys and tasked with training them to pick up a ball and put it into the box. The researcher believed that one group of monkeys was highly intelligent while the other group of monkeys was not smart at all. In reality, the monkeys were similarly intelligent, but the researchers were not aware of the fact. Consequently, the researcher spent less time training the supposedly intelligent monkeys and was more enthusiastic with them. For example, they were communicating with them and putting on a smile face. This behavior influenced the outcome of the experiment, illustrating the experimental effect.

Revised Answer (140 words):

The experimenter effect occurs when a researcher's expectations affect the outcome of an experiment. The professor in the lecture provided an example to illustrate this phenomenon. In this instance, a researcher was given two groups of monkeys and assigned to train them to pick up a ball and place it into a box. The researcher believed that one group was highly intelligent, while the other group was less so. In reality, both groups had similar intelligence levels, but the researcher was unaware of this fact. As a result, they spent less time training the supposedly intelligent monkeys and displayed more enthusiasm towards them, such as engaging in communication and smiling at them. This behavior ultimately influenced the experiment's outcome, exemplifying the experimenter effect.

Original Answer: Experimental effect refers that the expectation of the experiment of the participant will influence the result of the experiment. The experimenter effect occurs when a researcher's expectations influence the outcome of an experiment. (Changed "Experimental effect refers" to "The experimenter effect occurs" for clarity and accuracy) There are two groups of monkeys that need to be trained. In the example, two groups of monkeys were to be trained. (Changed "There are" to "In the example," for better context) But they tell one group of trainers that the monkey is intelligent. The researcher was told that one group of monkeys was highly intelligent, (Clarified who was told and used "highly intelligent" for better vocabulary) And another group tells another group that the monkey is not intelligent. while the other group was supposedly less intelligent. (Simplified and clarified sentence structure) And the result is that the monkey was thought to be intelligent and was trained more efficiently. As a result, the supposedly intelligent monkeys were trained more efficiently. (Improved sentence structure and clarity) But indeed, there is no difference with them. In reality, there was no difference in intelligence between the two groups. (Clarified meaning and improved sentence structure)

Original Answer: The professor in the last two years has been able to illustrate the idea of the human effort. The professor provided an example that demonstrates the experimenter effect. (原文中的“the last two years”和“human effort”与主题无关，已修改为更贴切的表述。) For instance, a researcher was asked to contribute to this project. In the example, a researcher was given two groups of monkeys to train. (原文表述不准确，已修正为正确的描述。) He found that there are various levels and all kinds of knowledge exists between humans and animals. He then established a team in which a group of volunteers was hired and selected. He showed that there is no difference between them. It took him two hours last time to complete the first of his math module. He found out that there is a system called the mathematical model. The model gives him a lot of time to talk to them a lot. The researcher was told that one group was highly intelligent, while the other group was less intelligent. In reality, there was no difference in intelligence between the groups. The researcher's expectations influenced his behavior and training methods, leading to different results in training time for each group of monkeys. This illustrates the experimenter effect.

With the supposedly intelligent monkeys, the researcher was more enthusiastic, encouraging, and communicative. However, with the supposedly less intelligent monkeys, he was less enthusiastic and did not try as hard. This difference in treatment led to the supposedly intelligent monkeys being trained faster than the other group. This example clearly illustrates how the experimenter effect can influence the outcome of an experiment.
