The ability to select specific traits, such as height or IQ, brought about by multiple genes is more complicated than most people realize.
Efficient connection pathways across the entire brain provide a neural network that supports general cognitive function and ability. Higher fractional anisotropy is associated with higher IQ.
Musical training may be beneficial for improving social skills and self-esteem in children, but there is little evidence to suggest learning music improves academic performance.
Higher levels of vitamin D during pregnancy were linked to increased IQ in children.
Frequent cannabis use was associated with a two point decline in IQ. The decline was primarily related to verbal IQ.
A new computational model can identify genes linked to autism and predict the level of intellectual disability in people with ASD by only using rare mutations in genes already associated with the condition.
Independent of IQ, decision acuity predicted performance in decision-making tasks. This factored higher in older adults and increased in light of parental education.
