In three autobiographical memory retrieval experiments participants reporte
d the contents of consciousness to a probe presented at early and late poin
ts during retrieval. Classification of the protocols according to the speci
ficity of the reported knowledge found that early in retrieval abstract kno
wledge predominated whereas at the later point, close to generation or form
ation of a memory, knowledge related to specific events was more frequent.
For some memories very fast and full retrieval was observed at the early po
int and this was independent of other concurrent processing demands. These
findings show that generative retrieval entails iterative access of autobio
graphical knowledge but this is not observed in direct retrieval.
