Research with autobiographical memories has distinguished between memo
ry narratives of specific events and summaries of many events blended
together. Depression has been associated with a reduced ability to ret
rieve and orally relate specific positive memories. This study explore
d the hedonic bias in memory through collection of written autobiograp
hical memories from 90 nonclinical college students whose mood was ass
essed for depression. Participants with higher depression scores recal
led significantly more summary memories in response to a request for a
positive self-defining memory than did participants with lower depres
sion scores. There were no significant differences in the number of si
ngle-event and summary memories when participants were asked for a neg
ative memory. We used J. A. Singer and K. H. Moffitt's (1991-1992) sco
ring system to distinguish between summarized and specific memory narr
atives.
