Abstract
In a re-examination of the recognition memory of Jon, a young adult with developmental amnesia due to perinatal hippocampal damage, we used a test procedure that provides estimates of the separate contributions to recognition of recollection and familiarity. Comparison between Jon and his controls revealed that, whereas he was unimpaired in the familiarity process, he showed abnormally low levels of recollection, supporting the view that the hippocampus mediates the latter process selectively.
This research was supported by the Economic and Social Research Council (ESRC Grant R000223887) and by a programme grant from the MRC (Grant ID: 65439) and the Intramural Program of the NIMH/NIH/DHHS for which we thank both of them for their support. The research was carried out at the Department of Psychology, University of Sussex, Falmer, BN1 9QH. We are grateful to Jon and to his parents for their very willing cooperation.
