Whole brain univariate analysis
The univariate group analysis provided little unequivocal evidence
that the activation patterns characteristic of immediate and long-term
memory retrieval patterns re-emerged during the monitoring task
(Fig. 5B). Searching for voxels that were more active during immediate
monitoring of word pair learning yielded two clusters, neither of which
overlapped with the immediate recall preferring clusters of the overt
cued recall task. In the opposite direction, clusters showing significantly
higher signal during long termthan immediate monitoring only partially
overlapped with the long term recall preferring clusters during the
overt recall task. In fact, only 17.4% of all the voxels that differentiated
between immediate and long term trials either in the overt recall or in
the monitoring task, were shared by the two tasks. To further detail
the difference in univariate activation between the monitoring and the
overt recall task,we investigated the response characteristics of clusters
