So from childhood to adulthood, which of the following change happened to the proportional genetic and environmental influences on intelligence? so what we learned about this typical pattern observed in a research on intelligence, this is development typically from childhood to adulthood.
00:30
So you can see how the pattern of intelligence developed.
00:35
So what we know is that the research indicates that the shared environmental influence decreased.
01:05
So a shared environmental influences factors such as the same family.
01:21
So in the childhood, this obviously have better or stronger influence on the intelligence, but when the child is growing up into adulthood, this shared family factor, they tend to decrease because when they share family, they have the same influence.
01:41
They have similar influence.
01:44
So obviously this would affect the intelligence, but when they grow up into adulthood, they become more independent.
01:51
So then they expose to different environment.
01:55
So the shared environmental factor obviously become less pronounced.
02:22
So i write down the explanation at the end.
02:26
When the individual become more independent, grow into adulthood, there will be less influence from the family and therefore the shared environmental influences obviously decrease.
02:39
The research also found out that the genetic influences increases...
