Negative information is better remembered than positive information, from which we predict that in comparison with negative retrospective evaluations, positive evaluations have a stronger correlation with end affect and a weaker correlation with peak affect. We confirm this.

Abstract: A vast amount of literature examined the relationship between retrospective affective evaluations and evaluations of affective experiences. This literature has focused on simple momentary experiences, and was based on a unidimensional concept of affect. The current article examines the relationships between evaluations of complex experiences, experiences involving both positive and negative feelings, and the retrospective evaluation of these experiences. Based on the idea that negative information is better remembered than positive information, we predict that in comparison with negative retrospective evaluations, positive evaluations have a stronger correlation with end affect and a weaker correlation with peak affect. These predictions are tested in two studies. We explore boundary conditions for these effects and demonstrate the implications of the asymmetry between positive and negative affect to various topics that are at the center of affect research: the dimensionality of affective experiences, the memory-experience gap, and the analysis of net affect.
