Over time, autobiographical memories demonstrate fixed affect (i.e., maintain initial affect), fading affect, flourishing affect (i.e., increased affect), or flexible affect (i.e., change from unpleasant to pleasant or vice versa). Walker and Skowronski argued that events low in initial pleasantness are more likely to exhibit flourishing affect and flexible affect and that unpleasant events are more likely to demonstrate flexible affect than pleasant events. However, because of the low frequency of flourishing affect and flexible affect events in individual studies, research had not examined differences between these event categories. The present study examined initial pleasantness ratings for fading affect, fixed affect, flourishing affect, and flexible affect events across four published studies. We expected and generally found lower initial pleasantness for flourishing affect and flexible affect events than for fading affect and fixed affect events. Implications are discussed.
