Carla finds evidence supporting a correlation between nurture and intelligence, which of these has she likely found? a, identical twins receive similar scores on an iq test.
00:14
B, adopted siblings vary greatly in their ability to learn new tasks.
00:19
C, children who are able to teach themselves to read are more likely to go to college, or d, children whose parents were running with many books perform better academically.
00:29
Okay, so this is the debate between nature and nurture.
00:32
How much of intelligence is inherent, and how much of it is dependent on the environment you grow up in? for this question, we're looking for something that shows that your intelligence is affected by your environment.
00:47
So if we look at a, identical twins, this is indicating a genetic basis.
00:54
If identical twins receive similar scores, then, well, they have the same genetics.
01:00
It could be caused by that.
01:03
Especially if they grow up in different households.
01:06
It's very, very common to use adoptive studies, where one of the children has been adopted and grown up in a different family, because then you can compare without the factor of shared parents, shared growing up in the same area.
01:24
If we look at b, adopted siblings very greatly, well, adopted siblings share the same environment, for the most part.
01:32
If they vary greatly, this is again, against nurture and again in favour of nature...
