Been There, Done That: Brain Mechanism Predicts Ability To Generalize
ScienceDaily (Oct. 23, 2008) — A new study reveals how the brain can connect discrete but overlapping experiences to provide a rich integrated history that extends far beyond individually experienced events and may help to direct future choices. The research, published by Cell Press in the October 23rd issue of the journal Neuron, also explains why some people are good at generalizing from past experience, while others are not.
Decisions are often guided by drawing on past experiences, perhaps by generalizing across discrete events that overlap in content. However, how such experiences are integrated into a unified representation is not clear, and fundamental questions remain regarding potential underlying brain mechanisms. It is likely that such mechanisms involve the hippocampus, a brain structure closely linked with learning and memory. The midbrain may also play a role, as its projections modulate activity in the hippocampus, and activity in both regions has been shown to facilitate encoding of individual episodes. Read on...
