when we yawn why does it makes other ppl yawn?

Answer 1

ok Contagious yawning is known to be more than coincidence: studies have shown that 40 to 60% of people who watch videos or hear talk of yawning end up joining in. But psychologists have long wondered what causes it. "It seems like such a hokey phenomenon," says psychologist Steven Platek.
To try to get to the bottom of it, Platek and his colleagues at the State University of New York in Albany sat subjects in front of videos of people yawning and tallied their responses to find out why we are susceptible or immune to contracting yawns.

The tests showed that those impervious to the trigger also struggle to put themselves in other people's shoes, the psychologists say. For example, they might be less likely to recognise that a social faux pas or insult could cause offence.

Identifying with another's state of mind while they yawn may cause an unconscious impersonation, the team suggests. The findings, reported in the journal Cognitive Brain Research, might also explain why schizophrenics, who have particular difficulty in doing this, rarely catch yawns.

This makes evolutionary sense, agrees Ronald Baenninger, who has studied yawning at Temple University in Philadelphia. Contagious yawning may have helped our ancestors coordinate times of activity and rest. "It's important that all group members be ready to do the same thing at the same time," Baenninger says.

Answer 2

I read a theory a while back that suggested that yawning was an evolutionary thing. When humans used to hunt for food, and one person yawned, it made the others in the hunting group yawn so they would all be synchronised and alert together. I've not found this theory since, but then I haven't looked for it either!!

Answer 3

The simple truth is that even though humans have been yawning for possibly as long as they have existed, we have no clue as to why we do it. Maybe it serves some healthful purpose. It does cause us to draw in more air and our hearts to race faster than normal, but so does exercise. There's still much we don't understand about our own brains, so maybe yawning is triggered by some area of the brain we have yet to discover. yawning is some form of communication.

Answer 4

I dont know the real cause but maybe it's because that others like you feel tired and bored and try not to yawn...that is until they see you...it makes them yawn as well.

Answer 5

Compounding the mystery is the odd way in which the contagious power of yawning is largely unconscious. We can see someone yawn, yearn to replicate the action ourselves, and do it, all without thinking about it. Other times we’re aware it is happening, though it still floats somewhere beneath the realm of reason and of purposeful actions.

Answer 6

Yawn is a body language. It means "I am so bored; I am sleepy". If you are brave enough to have the first yawn, it will encourage people to yawn after you.

Answer 7

Because it is a reaction thing, in nature if a lion yawns it is to tell the pride that it is time to sleep so they all yawn and, well, go to sleep. It's similar with us.

Answer 8

I think because you see the person yawn or hear them and your body says yawn too.

Answer 9

It comes from when we were cave dwellers and before we couild communicate with language. When one person started yawning, then the whole group did and then they knew it was bedtime. Especially helpful when the time of darkness fluctuates in the different seasons.

Answer 10

Excellent question, now I just have to work out the fact from the fiction above.... YAWN!!!!!!
