  • Ladies and gentlemen, hello.

  • It's a pleasure to be here. Today, we will examine

  • the differences between male's and female's brains seen in the lab,

  • and their relationship to behaviors.

  • This is said by Deyong Zhu, and I think many agrees:

  • (on screen) men, without women, is without fun; men, with women, is without joy of life.

  • Let's see why it is.

  • This is a male brain; this is a female brain.

  • The front of the left brain lights up when men speak. Both light up when women speak.

  • This difference in feature stems from a difference in structure.

  • This is called flat plastid, millions of cellulose between the two hemispheres.

  • It is a bridge connecting the two.

  • Girl's is thicker; guy's is thinner.

  • If your bridge is bigger,you run faster from right to left and left to right.

  • As expected, emotions are on the right, and language is on the left.

  • Girls tend to express emotions through language.

  • When a couple is arguing, the husband speaks 1 words, while the wife can speak 10.

  • On Teacher's Days, students will write thank you notes.

  • Girls will buy blank greetings cards and writes herself,

  • "Professor, I've graduated, and I'm working at this and that."

  • "My boyfriend is no longer the one you met last time."

  • Guys remember teachers as well, but they don't write themselves.

  • They just buy and send you a pre-written card saying "Thank You."

  • So, the difference lies here: V1, V2, V3.

  • V stands for "visual", our hindbrain.

  • It's our visual cortex. And V4 deals with colors. V5 deals with actions.

  • We can see that on the top, there is a parietal lob.

  • The "where" passway to the parietal lobe is bigger for men.

  • The "what" passway to the temporal lobe is bigger for women.

  • After reading this report,

  • you know why it is only useful to ask women the way.

  • Why? Women's V4 is bigger than men's.

  • V4 deals with colors and landmarks. So when a woman tells you the way, she goes,

  • "go straight, then turn right when you see a 7-11, then turn left at the McDonald's."

  • "Then on your right, you will see the red house behind the white church."

  • "There you go." Colors and landmarks.

  • As for men, their V5 is bigger.

  • V5 deals with distance and direction. So when a guy tells you where to go, he is like,

  • "go 5 km along Zhongzheng Road then turn to the east." Right?

  • Many women don't know how far is 5 km. They don't know east from west.

  • So this message is not very helpful.

  • The other day, I gave a speech in Hualien.

  • The Director of Education of Hualien was going to treat me a meal.

  • We and another teacher kept walking on the same road.

  • We couldn't find the restaurant.

  • So we stopped at a landmark, a big hotel in Hualien,

  • then we called the director telling him, "we are on the road, in front of the big hotel."

  • "Can you tell me,"

  • "is the restaurant on my left or right?"

  • I can just check like this and that, right?

  • But he said, "it's north of you."

  • So, women know how to read a map too, but if she's heading north, the map needs to be pointing north as well.

  • If she is heading north, but the map is pointing south, she tilts her head.

  • And if a woman is driving and gets honked at,

  • she immediately checks if she's doing something wrong, why are they honking?

  • But men would think they are honking at somebody else. It's not me.

  • So, we invited normal collage girls to the lab.

  • We asked them to think about a sad event in a NMR machine.

  • For instance, a cheating boyfriend, an argument with the boyfriend, and so on.

  • All at once, her whole brain lights up,

  • even the cerebellum.

  • When we asked men to lay in the NMR to do the same thing,

  • there were only a few spots.

  • That is why women are usually more depressed than men.

  • That is why we often say if it's none of your business, don't take responsibility.

  • Don't pay your husband's debt.

  • And now we've seen why women are the way they are.

  • There's this thing called serotonin.

  • It relates directly to our emotions, motives, sleep, and memory.

  • Anti-depressant drugs are called Prozac.

  • Prozac blocks the brain from recycling serotonin.

  • When there's more of it, you feel better.

  • We found that the rate that men make serotonin

  • is 52% faster than women.

  • Because it's so much faster, no wonder after a fight,

  • the wife is still upset, but the husband is already asleep.

  • Why? Because serotonin makes me feel better,

  • it's done already, so I fall asleep.

  • But the wife is like, "I'm still upset, how can you go to bed?"

  • So she wakes him up and keeps on fighting.

  • This has something to do with the brains.

  • For example, the wife complains that when the husband comes home,

  • he never talks.

  • The husband is like, "I can't stand her. She never stops talking."

  • "I can't get a moment of silence."

  • Let's check the brains and find out why.

  • men speak 7,000 words on average everyday. Women speak 20,000.

  • He already spend all his quota in his office.

  • So he doesn't talk at home.

  • The wife takes care of the kids at home, get them to eat or to sleep.

  • These aren't talking.

  • There are 20,000 words on her mind.

  • She needs to get them out within the 3 hours when the husband is home.

  • She can't get them all out if she doesn't constantly talk.

  • Therefore, as one can see, it's a brain thing.

  • Our fetus is originally a female one.

  • The "prototype" is a female fetus.

  • If you are of the XY genes, between 6 to 8 weeks of the pregnancy,

  • there will be male hormones, testosterone, generated,

  • setting up areas in your brain, called capa mental.

  • If without it, by default, you are a female.

  • A female has an ovary,

  • which is why she keeps on secreting estrogens until she's 2.

  • A male stops that at the 8th month.

  • And because of the estrogens, females are more sensitive to facial expressions, languages, and so on than males.

  • Females detects facial expressions 20/1000 second faster than males.

  • That is why people say women are more suitable as personnel managers.

  • Why? Once you say something wrong, and he or she gets mad,

  • you'd know it's time to stop because he or she is mad.

  • But when men see people flip out, they still don't know why you get mad.

  • Therefore, we can see in kindergartens, girls are about 2 years more mature than boys.

  • A 4-year-old girl would say, "that boy is this and that,"

  • ratting out all the bad things he's done clearly.

  • In order to be fair, the teacher would get the boy too,

  • and ask him, "did you do this and that?"

  • 4 years old as well, the boy can't even speak clearly, just repeating, "You! You! You! You!" Right?

  • Also, the class presidents before 6th grade are usually girls.

  • They speak clearly and are reliable.

  • However, in junior high, class presidents are usually guys, because the curve of growth has changed up.

  • For example, if there's a high school girl, she comes home.

  • She'll say, "mom, today at school, this and that happened. Somebody's been saying mean things about me."

  • "Some teacher has wronged me."

  • She'd tell her family. And when a girl breaks up, she'll call her friends, saying,

  • "I've been so good to him! He's a jerk! He broke up with me!"

  • And after half a hour, she will hang up.

  • And then right after, she'll call another friend.

  • She'll tell the same story. However, you'll notice,

  • she's changed her wording.

  • >From "this guy is a jerk, breaking up with me",

  • to "this guy is worthless, and I broke up with him."

  • Then she'll hang up and move on to other things.

  • Because she's dealt with her emotions.

  • But guys are different. A high school guy comes home.

  • The mom asks, "son, how's school today?"

  • He says "it is fine" or "I don't know."

  • The son speaks no more than 3 words to the mom.

  • When a guy is upset, he just closes his door and sulks by himself.

  • As one can see, males and females deal with feelings differently.

  • For example, when a husband sees that his wife is busy,

  • he asks, "can I help you with anything?" The wife responds, "sure."

  • "Take those potatoes, peel half of them, and then put then in the pot."

  • Next, when the wife is done, she opens the pot. she can't believe it.

  • We girls will never cook like that.

  • You either peel all of the skins, or don't peel at all.

  • How would you peel only half of the skins? You do that and starch all comes out.

  • But you can't scold him. If you do, he'll be like,

  • "you told me to peel half of them and put them in the pot!"

  • You can tell a significant difference.

  • Another thing people say is that women have got a 6th sense.

  • That is true. But what is the reason?

  • For males (top), their forebrain and hindbrain connect very closely, nerve fibers-wise.

  • As for females (bottom), their left and right brains are more connected.

  • Then why do females have a better 6th six sense than males?

  • Our attention is much like a spotlight projecting out on a dark stage.

  • If your spotlight focuses more narrowly, it is brighter.

  • But a female's spotlight is wider, it is not as bright, getting more information.

  • Not all information is going to get into your consciousness.

  • The ones that don't get in gets to your subconscious.

  • And your subconscious affects your decision making.

  • In the 70s, I was studying in the University of California in the US.

  • There's this young assistant professor.

  • She got robbed at an ATM.

  • It was 200 US dollars, and that was a lot of momey back then.

  • She was upset. She called the cops, and the cops asked her, "what does he look like?"

  • She said, "I was so nervous. I couldn't see his face clearly. I only saw his gun."

  • The cops were like, "that's too bad."

  • "You only saw the gun. How could I catch him?" That's it.

  • And then a week passed. She started to hate one of her graduate students.

  • She complained that this student ate hamburgers with onions and it smelled so bad.

  • He never showered. This and that.

  • We felt so weird. Graduate students in the US don't just take exams and get in,

  • they get interviewed and then get in. This person was already like that when he got in.

  • He's a hippie: a little bit chubby, with to-the-shoulders hair length.

  • He wears overall, ripped pants, bare-feet.

  • He is always like that.

  • But she said, "he's got an IQ over 140. It's delightful to teach and nourish the talented and all."

  • So we asked, "you wanted him then why don't you now?" We didn't understand.

  • 3 months passed, and the cops came looking for her. They caught a robber around the campus.

  • They said, "you reported, right? Can you come and identify?"

  • There weren't a lot of girls back then, so I went with her.

  • Five men standing over there. It's a one-way mirror. They see a mirror,

  • we see a window, right?

  • The second she entered, she said immediately, "the second one from the left!"

  • It means that she did see the robber, that's why she could recognize.

  • How does the second one from the left look?

  • Just like her graduate student.

  • Chubby, hair to the shoulders, overall, ripped pants.

  • So you realize, she did see the guy.

  • But because she was so nervous, the information didn't get into her brain, but her subconscious.

  • Therefore, when her student came talk to her, she felt insecure.

  • She kept driving him away.

  • But you are a professor, how can you drive a student away?

  • The front of our left brain is an explainer. It helps you find reasons for your behaviors.

  • It told her, "hamburgers with onions are stinky, and he's this and that."

  • So we can see,

  • We didn't know if she remembered it, but she had this feeling.

  • And this feeling drove her decision-making process.

  • So, we did a study, asking college students, "do you like this Chinese character?"

  • They were like, "are you kidding? I don't know any Chinese character. How will I know?"

  • We told them, "it's okay. We used to pay you $2 for a experiment. Right?"

  • "We'll pay you double this time. $4. Please help us."

  • The students thought they just picked randomly.

  • But that's not true. Before a Chinese characters showed, we would put a smiley face.

  • Two eyes, one smile, like this :)

  • But only for 30 milliseconds. For a thirty thousandth second.

  • They couldn't have seen it.

  • However, their choice goes from 50/50, yes or no,

  • to a 70% to 80% chance of saying, "yes, I like this Chinese character."

  • Similarly, we invited another group of students.

  • The same Chinese character, but with a crying face :(

  • They would be like, "no, I don't like this Chinese character."

  • Therefore, we can see that subconscious affects one's decision making.

  • Later, we did another study with kids.

  • We showed them 3 minutes of Tom & Jerry, the cartoon.

  • But in between, we input some pictures of a man hitting a dog, kicking it.

  • After the cartoon, the door opened and two men came in: same height, same clothes.

  • The teachers said, "children, I have something else to do now."

  • "There are two people here, and you can play with whomever you want."

  • The children went for this one, and not that one, because in the video, he kicked a dog.

  • The teacher said, "don't just play with the same person. Go play with the other, too."

  • The children were like, "you go!" "No, you go!"

  • I don't know why I don't want to, but you doing it is better than me doing it.

  • Next, we did the opposite. The other person kicked the dog.

  • Now everybody played with this one and not that one.

  • So it's not about their faces.

  • It's about their subconscious knowing that this guy hit a dog. I don't wanna play with him.

  • Therefore, if you are dropping your kid to the nanny's, and your kid starts to cry as soon as your car pulls into the driveway,

  • replace your nanny.

  • So we realize that subconscious does affect us.

  • There's this saying:

  • Small things, listen to your head.

  • big things, listen to your heart.

  • More often than not, you don't know why,

  • but we know it's the right choice.

  • When we were young, we all experienced this while taking an exam:

  • there's only 2 minutes left, and there're some multiple choices I need to finish.

  • What to do? Just put something in quickly.

  • Because if you put in something, you just may get it. If you don't, you don't.
