The mood-congruent judgment effect refers to the fact that when a mood
and an idea are similar in pleasantness, the idea will generally seem
better in some way. For example, when people are happy, they will jud
ge pleasant concepts as richer in their associations, pleasant attribu
tes as more applicable, and pleasant examples of categories as more ty
pical. This mood-related component of cognition is viewed longitudinal
ly among normal students for the first time here. The authors demonstr
ate that over time, changes in mood covary with changes in judgment in
normal individuals.
