Cognitive Ability and Disabilities

lecture 7 Cognitive ability and dis abilities ↓ IQ-measurement of your brain its very valid and stable and reliable. AND its avery strong predictor for social domain or educational domain S most are based on Single based genes afew genes. -what is average 12 - Is IQ of 115 high? M=100; SP = 15 Cognitive ability is related with genetic relatedness. Stronger genetic relationship-sincrease in cognitive ability for cognitive ability there are a lot of genetic information, but also slightly Environmental Family designs give info of .SA+C adopted: adopted apart gives. SA Mywins give A Twins design gives info of A heritability of IQ has a increase for genetics, dop in shared environment and a drop in unique environment. for children, part of their IQ is based on the input of parents and leachers. for adults its only genetics (biology takes over) la is based on verbal and spatial ability Scheidt, dan zic als je domme muizen uld slimme muiten zie je dat hun ginen verder Slimme/domme muizen produceren. Dit heeft ook te maken met de omgeving en of deze de of deze de genen triggert. see documentory 'klassern advise of teachers is based on SES voor middel-boar onderwgs niveau ondanks zelfde cito-score 530-535 humans don't mate random→ Assortative mating. ↳ you pich them on certain characteristics and genotypes are triggerd by some genotype. Genotype parents more similar than random → genotype of their offspring more alike → Stronger b2-correlation (since M2 is identical, there can't be an increase →heritability estimates Normal are lower more similar M2-D2-2 M2-02-2 -70-.50 -70-.60 80.2=40 =.10.2.20 1 heritability estimake is lower downside of same mating is that the offspring can get more of a specific gene which can cause some disorders to be more severe in the Child than it was in the parents for example with autism. both parents have cutiom, but its not protation problematic, they matk, get a child and child has big problematic autism. There are more differences between children other than only their genetics, Hasir second, third or first born is also playing a role. Oldest scores always highler: - Social explanation more evidence for this one → you get more attention and ther is more money for you - biological explanation mostly → mother creates antibodies due to pregnang. the hid is not completely hers In the case the anti bodies stays in her body after of sons birth. it & effects more for later children. because of x and y chromosome, female already has x.chromosome, so genetic material of girl is more similar to hers than of a son. the delest is in favorable position with respect to intelligence/cognitive ability box 7.1 je hebt een lest het een score. je hight You take ← of de DNA (genomel overeenkomt met de Subject (s). Hetzelfde doe je voor de lest (phenotype). the whole genes Sup heritability for Lo is approx. 0.3 there is an influence of genes on IQ missing heritability → het gedeelte verschil tussen moléculaire genen en M2 correlokites Voor IQ is het missing gedeelte heel groot en verwachting is dat het hitt snel lager wordt TQ is complexs Height Hight brown is correlated to the volume of your body and Endophenotypes in between of genotypes and phenotype ↑ environment plays a role in genes Size of your head is correlated with height and intelligence
