Emotions are not something unique to humans, and at the end of the movie, emotions are jumping up and down in the minds of cats and dogs. However, after human beings inherited the emotional system of their distant ancestors, they have evolved new tricks. Specifically, crying, laughing, and various other expressions. Expressions exist because people socialize animals and have strong social needs, or information transmission needs. For the ape-man who has learned to walk upright, when the two apes meet, it is obvious that the first thing the eyes see is the face. In line with the principle of making the best use of things, the face has naturally developed into the most effective notice board in early human beings. Although the old cow also burst into tears before being stabbed, there is no other animal that can cry so freely and shed so many tears like a human. As for laughter, it is even rarer among animals. Even if an animal can make a similar sound, the upward movement of the corners of the mouth cannot be reproduced. The variety and sophistication of expressions are unmatched by any other animal. Therefore, before the emergence of abstract ability and later language, people have actually established a complex communication system with the expression of various emotions. Described in the framework of this film, the operations performed by the five basic emotions on the center console are not just emotional catharsis, but emotional expression.
So, until the end of the movie, Riley's biggest threat is not worry, let alone anger and fear, but Lele. From the second second of Riley's birth, Lele and Youyou competed for the console, the movie revealed a terrible fact, Lele didn't know why Youyou came, not only that, she has also adopted a policy of suppression, continued Ground deprivation reduces worry about console use. In the next shot, Riley is just over a year old. This really skips the hardest part of the story. Because in infancy, children who can cry have milk to eat, and those who can't cry starve to death long ago. With such an unreasonable bully as Lele, how did Riley grow up healthy? It can only be considered that she is indeed very lucky to live in an extremely superior environment, and the guardian can actively identify and meet her various needs, saving her from worrying about a lot of work.
Next, the main line of the story unfolds. In addition to interspersing and introducing various working mechanisms of the brain, it is to set things right and let emotions return to their respective places. What’s interesting here is that while Riley’s abstract thinking and language skills remained unaffected throughout, the lack of emotion severely affected her thinking and communication. In other words, empathy actually includes compassion. Whether it is the lack of perception or the ability to express emotions, the effect of communication with the outside world must be greatly reduced.
Memory:
The most important key word in the movie after emotion is memory, and the gain and loss of core memory constitutes the main plot conflict of the story. But unfortunately, although brain science has working memory (short-term memory), long-term memory, etc., it seems that there is no such thing as core memory. In other words, while it is true that there are moments in life that are so deeply imprinted in the mind that they can be vividly recalled decades later, there is no evidence that a certain personality trait in a person is primarily established in a few seconds. Chung's life fragment. Of course, some extreme cases must be excluded, such as the few seconds when normal people are scared crazy. So core memory is just a concocted concept for storytelling.
Furthermore, while the film depicts memory as many fragments, it does not do a good job of portraying how working memory or short-term memory works. In fact, the short-term memory of the human brain is extremely limited, and there is no large cache that can put down memories for the whole day and file them when they sleep. During the day, our cache is probably updated many, many times.
As for the storage of long-term memory, it is similar to the description in the movie. It exists in some memory cells on the cerebral cortex. By recalling long-term memory to working memory from time to time, people can achieve the consolidation and strengthening of long-term memory. . But sometimes, like the commercials in the movie, the recall is out of control.
Some unconsolidated memories disappear, but the brain doesn't thankfully carve out a garbage dump for those memories. So disappearing is probably like an elephant popsicle. If it is said to be gone, it will be gone, leaving no trace. Now we know that there is no factual basis for the statement that the human brain only uses 10%, so the memory cells vacated by the disappeared memory should be used to undertake new memories. In this way, in the process of continuous replacement, although we have inherited some early skills or cognitions, we have actually become another person, and we can't even sit down with the self 20 years ago and talk about going together. people.
Thinking:
In the movie, Riley's thinking is mainly driven by emotions, and abstract thinking ability is only regarded as a subordinate workshop of the whole system. However, the operation mode of this workshop is still quite close to what scientists understand. It is by stripping the unnecessary details of things that human abstract thinking makes it possible to transmit and reproduce complex information. With the development of evolution, language (and even words) eventually became the best form of abstract thinking, and formed a positive incentive for thinking ability. This is why, although TV and movies are loved, books are the best carrier of wisdom.
Dreams and the subconscious:
The subconscious and dreams do not have exclusive brain areas, and the operation mode of invoking related memories is very similar to that of waking, which is why the central control room needs to keep people on duty. In fact, human brain activity during sleep is far more active than what is shown in movies.
