Q

cimmon IQ tests and neurodivergence…

A

some adjustments can be done e.g. colourblind versions however tasks often applied without adjustments so those who are neurodivergent may be disadvantaged.

Q

brain volume and IQ

A

2015 a meta analysis found a positive analysis however there was a publication bias- favoured studies with positive correlations and those with non significance were ignored.
