The Surprising Link Between Fluid Intelligence and Sleep Deprivation

Originally Published 2 years ago — by PsyPost

A study published in the Journal of Sleep Research suggests that individuals with higher fluid intelligence may be more vulnerable to the negative cognitive effects of sleep deprivation. Contrary to expectations, participants with higher fluid intelligence made more mistakes on cognitive tasks after experiencing sleep deprivation compared to those with a normal night's sleep. The study highlights that higher-order cognitive functions, which involve complex thinking and problem-solving, are positively related to intelligence only under optimal sleep conditions, but become more vulnerable to sleep loss. Further research is needed to understand the complex relationship between sleep, intelligence, and cognitive performance.

The Link Between Intelligence and Problem-Solving Speed

Originally Published 2 years ago — by PsyPost

A recent study challenges the conventional belief that intelligent people think faster. The study discovered that people with higher fluid intelligence, which is a measure of problem-solving ability, actually took more time to solve difficult tasks compared to those with lower fluid intelligence. The researchers stumbled upon the finding while creating personalized brain network models based on data from the Human Connectome Project. The researchers proposed a trade-off between decision-making speed and accuracy, which aligns with theories from fields like economy and psychology on fast and slow thinking. The study provides valuable insights into the relationship between intelligence, decision-making speed, and brain network dynamics.
