Literally doing a psychology course and this was covered but thanks for this. Now I have a study reference for exams
Crash course has a section dedicated to Psychology hosted by Hank Green! :)
same
i just finished watching a video about those triplets that were separated at birth for a study that tried to answer this question. and experimental design when it comes to these questions is so important because it can easily cross into unethical territory
He reminds me so much of Le Var Burton, and I love it.
I was trying to think of who he was reminding me of and this is the answer. His tone and rhythm of speaking is really close.
Hit the Chandelier note. Dang
This lad's a hoot! Truly enjoyable!
I got the Noid reference. I loved the video game.
Good thing there are still cats!
What a great series! ❤
One question I have is, in the segment about height, how exactly did you measure that 80% is genetic and 20% is environment? What does that even mean?
when i was small i used to think that people shrank as they got older.
Yes the environment can affect complex traits such as intelligence. However, in genetics there is something we call a phenotypic maximum, which refers to the upper limit of an organism's potential traits, determined by its genes
Dr. Sammy got some strong LeVar Burton energy
Nice
At 11:07 I was reminded that dominos made a video game in the early stages of game development.
I would definitely agree and say it's a combination of both contributors(genes/shared environment)
However according to the behavioral laws of genetics, the effect of the genes>shared environment
Had a debate on this for my Psychology class
Don’t forget the third factor DEVELOPMENT.
oh man, I remember that! 😂😄
Both
Black and white mentality, which is rarely true in the big scale and in general! It’s just a mix, and sometimes one thing is more effective than the other, but n the end i think nature is the base and the main cause of capabilities! I’m not expert, just my simple thoughts
Hi how's it going watching from Broomfield Colorado
you are talking LeMarche Genetic,,, Original disproved, but now shown as mixed with what most people understand as Darwunian Evolution
D'NAchos?
AAAAAAAAAAAAAAAHHH THE JELLYFISH LAMP!!!!!!!
Now I want a cookie!
Woah Never been early
So people from a low IQ group are more likely (on average) to have a low IQ? But given environmental factors have the ability to increase it?
I thought coconut crabs were a lot bigger than that. 🤔
noice
Nature nurture nachos
my professor is making me pick only one ughhh
0:20 Meh, I’m gonna say 60% Nature 40% Nurturer, so it is just enough that you can’t ignore your responsibility but not so much you can claim the true cause of the successful.
Either way, it's the parents fault 😅
My family, mom- brown eyes,brown hair, my dad- blonde hair ,blue eyes. 5 girls- 5 boys
Kids- 2 girls- blue eyes
3 girls -brown eyes
2 boys -blue eyes, 3 boys- brown eyes
All brown to dark brown hair. No blondes
2 boys- 6 ft- 1 boy -5ft- 2 boys 5'8"
All girls 5'4" to 5 ft.
Mom- 4'9" Dad 5" 4'
We are all over the map!
Nurture is important but nature ALWAYS has the final say.
What studies do you base that statement on? You clearly did not pay attention and don´t want to learn either.
Not really epigenetic is thing
Deep bro.
