Neural efficiency hypothesis
open-in-new
<p>The neural efficiency hypothesis proposes that while performing a cognitive task, individuals with higher intelligence levels exhibit lower brain activation in comparison to individuals with lower intelligence levels. This hypothesis suggests that <a href="/facts/Individual_Differences/5uhL9GaA">individual differences</a> in <a href="/facts/Cognitive_abilities/8L95q3bX">cognitive abilities</a> are due to differences in the efficiency of neural processing. Essentially, individuals with higher cognitive abilities utilize fewer neural resources to perform a given task than those with lower cognitive abilities. </p>
