Researchers have identified a neural mechanism that supports advanced cognitive functions such as planning and problem-solving. The mechanism distributes information from a single neuron to larger neural populations in the prefrontal cortex.
In terms of general intelligence, rocket scientists and brain surgeons are no smarter than the general population, researchers report.
In order to better understand the role that knowledge serves in human intelligence, it is essential to look beyond the individual and focus studies on the community overall, researchers say.
Cognitive flexibility, an ability to switch between different concepts, or adapt behavior to achieve goals in a novel or changing environment, is a key player in both learning and creativity.
Prescribing SSRIs during late childhood to those with genetic risk factors for psychosis can reduce the deterioration of intellectual abilities, a new study reveals. SSRIs appear to have a neuroprotective effect for certain brain areas associated with the onset of psychosis if provided early.
Average IQ was significantly lower for adults who were born with either a very low birth weight or born very prematurely, a new study reports.
Independent of IQ, decision acuity predicted performance in decision-making tasks. This factored higher in older adults and increased in light of parental education.
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.
Frequent cannabis use was associated with a two point decline in IQ. The decline was primarily related to verbal IQ.
