School life is relatively easy for Lin Fei, although the course schedule is very full, but it is very fulfilling. The professors and tutors were also kind to the good-looking boy, especially after he completed the class assignments and reports perfectly.

Several roommates also have their own ideas, after all, it is the top university in the world, and the students who are admitted are not as simple as they seem.

In terms of learning, apart from general education courses, professional courses have really brought Lin Fei a lot of gains.

Perhaps because of the professor's sense of responsibility or other reasons, the lectures in the cognitive psychology major were very thorough, although there were only a few students in this major and less than 20 (the others were all bastards from other majors), the professors still tried their best to explain the relevant knowledge, which benefited Lin Fei a lot.

"Cognitive psychology is concerned with the psychological mechanisms that underlie human behavior, and at its core are the internal mental processes that occur between input and output. But we can't look directly at internal mental processes at the moment, we can only speculate by looking at what is input and output. "On the stage is a middle-aged man who is very well-dressed, and he is also the head of the Department of Cognitive Psychology, it is said that the dean specially spent a lot of money to invite him for this course, called Chen Jiajun, who seems to be highly evaluated in the professional field, Lin Fei has the impression that his mother's paper has also cited each other's articles.

"So, the method we use is to infer unobservable mental processes from observable phenomena, Jason, what do you think are the methods we commonly use?" He scanned the classroom and stared at a student in the corner who was playing with his phone.

"Ah, uh, I think it's possible to give the observer a stimulus and then see how he reacts, and then extract information from that?" He lowered his head, his eyes were a little wandering, obviously he was addicted to his mobile phone just now and did not pay attention to the lecture.

Jason is a finance major, and he came to study cognitive psychology entirely to brush up for general credits, so naturally he won't pay too much attention to this course.

To be precise, most of the people in the classroom came to the class with the attitude of brushing credits for this course. If it weren't for the fear that the roll call would not be deducted, I am afraid that I would not even be willing to come to the classroom.

"Yes, please be seated." Professor Chen smiled and nodded, this smile looked very reluctant, "What Jason just said is our most commonly used and most basic research method, which is called the 'reaction time research method'. ”

"Of course, it's not as simple as he says. Let's assume that a person looks at the letter A projected on the screen, and if the projection time is very short, such as a millisecond, then the person will not see anything, which means that perception is not instantaneous; If the projection time is longer, say five milliseconds, then the person will see something, but not know what it is, which means that perception has been generated, but discrimination has not yet been generated; If the projection is long enough for one to see that the letter is not C or D, but not to be able to tell whether it is A or F or K, then the person has a partial discrimination. From this, one can determine the time it takes to fully discern, partially discern, or just to see that something is there. All this suggests that perception is cumulative, and it consists of several specific stages. ”

"And these are just the foundations of cognitive psychology, and in the later advanced psychology and advanced cognition, everyone should use this as the basis and use it to play."

His expression suddenly became a little mysterious, and he squinted at the listless students, not knowing what he was thinking.

"Students, I don't know what you think of computers?"

He tapped the blackboard to draw the students' attention.

As the blackboard was knocked, Lin Fei inexplicably felt a shock in his spirit, and unconsciously became interested in Chen Jiajun's question, this interest came very strangely, with his emotional control ability, there should be no such fluctuations.

He immediately raised his head, and Professor Chen Jiajun, who was ordinary at first glance, instantly became mysterious.

The classmates around him also changed their lifelessness and spoke enthusiastically as if they had been beaten with chicken blood.

"A great invention across the ages!"

"Saving a lot of time has greatly improved the efficiency of scientific research and manufacturing in all aspects."

"It also enriches people's spare time."

The variety of answers seemed exciting.

"Yes, computers are great inventions." Professor Chen nodded, clicked the mouse, and a classic desktop image appeared on the projection.

"John von Neumann, inventor of the computer. The computer is one of the most advanced scientific and technological inventions at the end of the last century, which has had an extremely important impact on human production and social activities, and has developed rapidly with strong vitality. Its application field has expanded from the initial military scientific research application to all fields of society, and has formed a huge computer industry, which has led to technological progress on a global scale, which has triggered profound social changes, and computers have spread all over ordinary schools, enterprises, and institutions, and have entered the homes of ordinary people, becoming an indispensable tool in the information society. ”

"Of course, from my own professional point of view, I think computers have a bigger impact on psychology!"

"The human brain is actually an information processing system similar to a computer, firstly, the environment inputs information to the sensory system, that is, the receptors, and the receptors convert the information; Before the converted information enters the long-term memory, it needs to be reconstructed, identified and compared by the control system. Memory systems store symbolic structures that can be extracted; Finally, the reactor reacts to the outside world. That is to say, the host of the computer is very similar to the human brain, and the facial features, limbs, and even other tissues and organs are equivalent to the reactor of the computer. ”

"Some of you have heard of the profession of psychotherapist, and some of you may become one of them in the future, as a more advanced psychological practitioner, we must modularize the treatment object."

He paused, then continued. Hearing the word healer, Lin Fei immediately became interested, and several classmates around him who were obviously from relatively poor backgrounds also began to take notes seriously, obviously the high salary and various benefits of the healer profession mentioned in the news made them very excited.

"Generally speaking, human cognitive activity is a unified whole of cognitive elements interconnected and interactive, and any kind of cognitive activity is completed with the cooperation of other cognitive activities related to it."

"In the process of human cognition, the relationship between context and context is very important. It not only includes the contextual relationship of the linguistic materials that people come into contact with, the relationship between the top and bottom, the left and right, and the sequence of objective things, but also the relationship between the original knowledge, the original knowledge and the current cognitive objects in the human brain. ”

"What you have to do as a therapist is complicated, but it's easy. Of course, I mean if you become a healer. His voice was very calm and deep, and he couldn't help but tap the blackboard a few more times.

"It is to control the input of information and consciously control the output of response information."

I don't know what the reason is, but the atmosphere in the class, which was still lively just now, instantly became low again, as if the excitement of the previous two minutes was just an imaginary illusion.

"As for how to control the input of information, it's not part of this basic course, and you'll learn it next year." He closed the book gently, not very satisfied with the reaction from the audience, he seemed to have wanted to say more about the healer, but there were so few students in the audience who really cared about him that he changed his mind.

"Okay, let's go here for this class first, let's get out of class."

With a wave of his hand, Professor Chen walked quickly towards the door, the disappointment on his face was very obvious, and when he left, he glanced around the classroom, his eyes passed by Lin Fei and paused slightly, and then left the classroom, not knowing where he disappeared.

"It's amazing, but I always feel like Professor Chen is a liar..."The speaker is a foreign girl, her name is Stata, a very masculine name, but she is very weak, wearing heavy black-framed glasses, ponytails, sundresses, very much like a little girl next door, just look at it will make people full of protection.

She is a classmate who is more interested in the therapist profession just now, it is said that the family conditions are average, and there is a younger brother who was born with a disability, but life did not overwhelm her, relying on work-study and various after-school jobs, this girl was still admitted to this school with excellent grades, and successfully obtained a student loan to complete her studies.

"Maybe he's talking too much at once?" Lin Fei smiled and sent a message back to Vera while packing his schoolbag.

Seeing this, Stata didn't say anything more, and quietly packed up the textbook, but couldn't help but peek at Lin Fei out of the corner of his eye.

Many girls in the courtyard are secretly betting on who can soak Lin Fei first, Sun Xiaoxiao has the greatest probability, but Lin Fei seems to have a girlfriend in his hometown and is not interested in school girls.

Starta also has a good impression of Lin Fei, but he seems to be very sober about his own conditions, and has never done anything out of the ordinary.

"The professional class is quite interesting, but the teacher always talks half and leaves half, which makes people a little uncomfortable." Lin Fei thought about it and felt that there was no problem, so he pressed the send button.

"I'm really envious, we feel that teachers and students don't have any desire to teach and learn, and the classes are very mechanical, but they are super keen on club activities, playing ball, singing competitions or something, and I always feel a little bit out of it. How are you over there, are there any girls chasing you? ”

"I didn't pay attention, I just want to study hard now (laughs), but you, have you adapted?"

"I don't believe it! It's okay on my side, after all, it's in the province, and I'm used to it. ”

Then the two fell silent, and although it was only for a short month, the two quickly lost their common topic because they had not seen each other.

The two of them are not the same type, if it weren't for each other's fire-like enthusiasm, Lin Fei should still be single in this life, after all, the body is only in his teens, but the mental age of several lives is already middle-aged and elderly, and it is not normal to be interested in Vera.

Silently closing the phone, Lin Fei looked up and saw Sun Xiaoxiao waiting for him at the door, shook his head and walked out of the classroom.

"The president is very interested in you, are you interested in meeting you?" She quickly stepped forward to declare her sovereignty and hugged Lin Fei's right arm hard.

"President? Club president? Lin Fei thought for a while, "Also, the school club... It's totally overthinking. ”

"Yes, the club, but he is only the nominal president, after all, the president of the club must be a student, in fact, many of the brothers and sisters who have graduated from our club are the key figures. So why don't you go and meet up? ”

"Stay late, there's been something late."

"Okay, then I'll wait for your news and go to dinner together, right?"

A cold gaze swept over, Lin Fei suddenly felt a chill in his body, this was a feeling he had never felt since he first accepted the wish to come to the vampire world, it was like encountering a natural enemy, everything around him was pulled away by external forces, he couldn't hear Sun Xiaoxiao's chattering words around him, and he couldn't feel the softness of the other party's chest, as if he was the only one around.

He immediately looked up, and unexpectedly, it was Professor Chen Jiajun.
