Who would study psychology if they didn't have some kind of problem?

Chapter 301 Data Pollution in Experiments
The experiment proceeds to the next step.

The computer screen went black and stopped refreshing the images.

Nan Zhuren provided real-time instructions: "Next, our headphones will play several different pieces of music or recordings. Please respond to these sounds as naturally as possible..."

……

About twenty minutes passed in a flash.

The male student emerged from the room, looking somewhat dazed. After taking a deep breath, he greeted Ms. Zhao, a teacher he knew well, and then said goodbye.

Teacher Zhao looked at the male student's dazed state and fell into deep thought.

After Nan Zhuren came out of the room, Teacher Zhao suddenly asked, "Teacher Nan, is what you made for the students the same as what you showed me last night? Why did they react so strongly?"

Her tone was full of curiosity, and also carried a hint of longing.

To get Teacher Zhao to cooperate with the project, Nan Zhuren and others naturally let Teacher Zhao experience the experimental process himself the night before.

But compared to the expression on the male student's face when he left, Teacher Zhao felt that her own experimental experience was much less interesting.

It's just an image that evokes emotions, so why does that student's expression subtly convey a sense of exhilaration?
Teacher Zhao was actually a little envious.

Nan Zhuren nodded matter-of-factly: "Of course it's the same."

"As for why they reacted so strongly... it's probably because their usual school life is too stressful."

Nan Zhuren offered a possible guess, which he felt was the answer: "In their daily studies, in order to maximize their learning efficiency, they neither spent long periods in a positive mood nor were they immersed in a negative mood for long periods—but rather remained in a relatively calm emotional state."

"Therefore, in this kind of [emotion-inducing] experiment, they were constantly stimulated with different emotions, which gave them a 'stimulating experience' similar to riding a roller coaster, and unexpectedly produced a relaxing effect and even a stress-relieving effect."

Nan Zhuren shrugged: "Of course, such unexpected effects cannot occur in everyone. Our goal is not healing, but information gathering."

Teacher Zhao nodded thoughtfully, then looked at Nan Zhuren as if he wanted to say something but hesitated.

Nan Zhuren, however, noticed something else: "Wait, you just said, 'Why are their reactions so strong?' right?"

Teacher Zhao realized, "Yes, Teacher Chong has already finished too. He told me to call him after you finish."

……

After all, this is my junior's first project, and he is currently the first student subject he has worked with in his first project.

As the senior student, Chonghui was still somewhat worried.

Therefore, he deliberately paused after collecting the data from the first subject to check his junior's experimental procedures and see if there were any problems. If there were any operational errors, he could correct them as soon as possible to prevent his junior from compounding the mistakes and ending up with a bunch of unusable data.

High-quality project progress is far more important than so-called high-speed progress.

After hearing the knock on the door, Chonghui came out of the room.

"Did you do a lot of experiments before, junior?"

He asked while fiddling with Nan Zhuren's instruments.

Nan Zhuren checked his memories and replied, "Not many."

Indeed, during Nan Zhuren's postgraduate studies at Jiangda University, after Lin Lilin discovered Nan Zhuren's talent for counseling, he consistently arranged for Nan Zhuren to do counseling instead of experiments.

He might have even been thinking of having Huang Xin write a paper and having Nan Zhuren co-author it.

Speaking of which, I wonder how Lin Lilin is doing lately. I wonder if she's still on liquid food. Maybe I should find a chance to visit her?
In short, the data collection section adapted from the "emotion induction" experiment is indeed closer to the components of basic experiments than to psychological counseling.

It's not an area that Nan Zhuren is particularly good at.

Upon hearing this, Chonghui perked up, but at the same time breathed a slight sigh of relief.

"Then let me see how you do it..."

As he spoke, Chonghui turned on the video recorder, focused intently on watching the playback, and prepared to pause at any time.

Then, after playing it all the way through, Chonghui looked up at Nan Zhuren.

Then, out of a sense of caution, he looked at it again.

"Is there a problem?" Nan Zhuren asked.

“No problem…” Chonghui quickly finished reading it a second time.

He thought about it for a moment and decided it was a good thing.

“Your operation is quite skilled… it’s just that the part where you personally read the instructions was a bit slow; we’re not really conducting a rigorous experiment, so displaying the instructions directly on the screen would be more efficient.” Chonghui thought for a moment, “but that’s not a big problem.”

"We can make the student schedule a bit more compact from now on, let's collect the data quickly."

Nan Zhuren nodded.

Chonghui nodded slightly, but his thoughts were elsewhere.

The process of this project went surprisingly smoothly.

Back in Beidu, Chonghui also mentored new students in research groups, but back then, facing those clear, innocent eyes, he only felt a headache. Those younger students knew nothing; he was basically their babysitter.

But at this moment, facing Nan Zhuren, who didn't need to be taught anything, Chonghui felt inexplicably uneasy.

I always feel like I'm a bit superfluous.

They even wanted to make conversation.

"Hmm... let's just record and collect data like this for today." Chonghui racked his brains and felt he had found a point that needed to be emphasized. "But after we get back tonight, we'll summarize and check it again."

"?"

Chonghui nodded in agreement.

This junior colleague is a natural talent, there's no way to compare; but I do have some research experience that I've accumulated over time that I can pass on, something that talent can hardly compensate for.

I'll teach him now, because in a year or two I might really be left only able to rely on someone else.

Faced with Nan Zhuren's questioning gaze, Chonghui said, "We are currently building a database, but the collected data may contain a lot of interfering data. If we include it rashly without screening, it may cause pollution."

Chonghui rattled off a list: "For example, some students who are already in a repressed state of mind might actually feel pleasure when they see painful images; some students who like R18 games might feel excitement when they see gory images, and so on. These behaviors that are inconsistent with the mainstream should be appropriately eliminated."

Chonghui continued, "After we get back, we can first..."

“That way, I can mark any inappropriate expressions directly,” Nan Zhuren replied matter-of-factly.

"...First, compare this batch of data with Beidu's [Metadatabase] and remove those with significant differences...wait a minute."

Chonghui blinked, realizing that something was wrong.

"You said to 'label' it, how do I label it?"

Hear the question.

Nan Zhuren replied matter-of-factly: "I know exactly what kind of emotions these emotional induction materials are meant to evoke."

Just as one can immediately know what a question is trying to assess when taking a psychological test, understanding the purpose of the material presented is also one of the fundamental qualities of psychology students.

"When I find that the emotions exhibited by the test students are inconsistent with the emotions that the material is meant to evoke, I immediately mark it and then don't enter it into the database."

Chonghui looked at Nan Zhuren and remained silent for a moment.

　I'm still not quite right in the mood, so I'll go chat with some psychology classmates tonight.

　　I have no classes or other chores during the day tomorrow, so I can finish the second update.
