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.
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.
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.
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.
In terms of general intelligence, rocket scientists and brain surgeons are no smarter than the general population, researchers report.
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.
Early-life exposure to car exhaust from leaded gas reduced the IQ of around 170 million Americans, a new study reports.
Damage to the multiple demand network, a brain network associated with general intelligence, causes people with dementia to struggle to adapt to changes in their environment
Despite there being no differences in IQ or general intelligence between males and females, men often overestimate their IQ's, considering them to be higher than females. Researchers explore why this matters in an educational context and evaluate why females often underestimate their intellectual abilities.
Musical training influences visual working memory, researchers discovered. The study found regions of the brain may share a common component that influences both visual and musical working memory.
