"Designers need to understand psychology"-seventh-people are social animals

Chapter sixth source of human motives

we underestimate the importance of socializing to people. People use all the things around them to socialize, including science and technology. This chapter will cover the science behind social networking .

63. The maximum number of "strong relations circles" is 150 people

Points:

1) Dunbar number

Robin Dunbar (1998) studied different animal species. He wondered whether the number of stable relationships in social groups was related to brain volume (especially the new cortex). He proposes a formula that calculates the upper limit of the number of different groups, which anthropologists call the "Dunn numbers" of species.

2) Maximum number of human social circles

Dunbar inferred the maximum number of human social circles. According to his calculations, the human circle is capped at about 150 people. More precisely, he calculated the figure is 148 people, rounded to 150 people. Of course, there is inevitably a greater error, the number of 95% confidence interval is 100 to 230 people (lest the statisticians questioned).

In fact, 150 people refer to the close circle size. If a circle is under great pressure, it will stabilize at 150 people and be geographically close. If survival is less stressful or the organization is dispersed, the Dunbar estimate will be capped lower.

3) There is a limit to the number of stable social relations

This restriction refers to the number of people you can maintain a steady social relationship with. In such a group relationship, you know everyone and their relationship to each other.

64. People are born to imitate and sympathize

Points:

1) mirror neuron activity

Watching other people's movements will also trigger your brain neuron activity, just as if you were doing your own action. The neurons of these activities are called mirror neurons.

65. Doing something together will connect people together

Points:

1) People need to synchronize activities to get a sense of well-being

It is believed that online intercourse should also follow the offline social rules .

When you sign in to a website or use an online program, you anticipate feedback and interactions with your site, and most of the expectations can correspond to expectations of interpersonal interaction. If the page does not have feedback or load time too long, it is like the object of the chat does not look at you, ignoring you. If a website asks for personal information prematurely, it's like an outsider suddenly wants to be close to you. If the site does not save your information, it is like the other side forget you, think for a long while to think of the original you know.

Example:

You walk down the road, and suddenly someone walks up to you and says, "Would you like to know more about how to support President Obama's policy?" "You answered," thought. Then reached out to pick up the booklet he had handed over. But suddenly he took back the booklet and said, "Oh, I'm sorry." If you want to know more or want to read this booklet, you must first tell me your email address and zip code. "Then forget it!" "You say you're leaving." And so on He shouted, "Well, it's okay not to email and zip." "But you don't trust him, and you don't want to talk to him anymore."

67. The degree of lying varies depending on the medium

There are a variety of ways to communicate: write letters, email, face-to-head conversations, make calls, and send instant messages.

67. The speaker synchronizes with the listener's brain when communicating

When someone speaks, your brain synchronizes with the speaker.

Points:

1) Synchronization + expected = Understanding

In Stephens's experiment, the higher the degree of brain synchronization, the more the listener understood the speaker's views and information. By observing the activities of different parts of the brain, Stephens found that the parts of the brain responsible for prediction and anticipation were activated. The more active they are, the more successful they communicate. Stephens found that the parts of the brain that were socially responsible were also synchronized, including areas that were critical to successful communication, such as those that understood the beliefs, desires, and goals of others. Stephens also speculated that mirror neurons also play a role in synchronizing the brains of speakers and listeners.

68. The brain responds uniquely to acquaintances

70. Laugh to connect people together

Provine (2001) spent a long time observing why and when people laughed. His group observed 1200 people around the world involuntarily laughing. They recorded the gender, the situation, the speaker, the listener, and the content of the conversation. Here's what they found.

　　

71. People are more likely to distinguish fake smiles from video
