Future scenes imagined from rewarded words felt somewhat more vivid
Future scenes felt more vivid with rewarded words than with new words. With neutral words, the difference was smaller.
The study, in plain language
On the first day, some words were linked to small rewards and others to no outcome. The next day, each person used these words to imagine a possible personal event in a particular place and at a particular time.
While they imagined, the scanner recorded activity in regions associated with constructing scenes and reward. Participants reported greater vividness with rewarded words than with new ones. With neutral words, the gap narrowed and became uncertain.
The comparison suggests prior experience can color both the scene someone constructs and the brain signals accompanying that exercise. It suggests, but does not prove: there were 21 people, and no later decision was measured.
The key idea
Prior reward experience was associated with somewhat more vivid future scenes and changes in brain signals.
Something to think about
A detailed imagined scene can feel convincing. This research invites us to separate that vividness from what we actually know about the likelihood of it happening.
