There is great interest in the cognitive consequences of hippocampal volume loss in developmental amnesia (DA). In many DA cases, volume loss occurs before the hippocampus is fully developed, and yet little is known about the locus, extent, and distribution of damage in these cases. We used high-resolution MRI to manually segment the medial temporal lobe(More)
Over 50 years of research has revealed a critical role for the hippocampus in the formation of long-term declarative memories. More recent evidence has specified the functions of the hippocampus as the binding and comparison of memory representations that may be used under shorter, as well as longer, delays (Olsen, Moses, Riggs, & Ryan, 2012). Hippocampal(More)
A fundamental assumption underlying most current theories of amnesia is that memory impairments arise because previously studied information either is lost rapidly or is made inaccessible (i.e., the old information appears to be new). Recent studies in rodents have challenged this view, suggesting instead that under conditions of high interference,(More)
We investigated whether overt shifts of attention were associated with visuospatial memory performance. Participants were required to study the locations of a set of visual objects and subsequently detect changes to the spatial location of one of the objects following a brief delay period. Relational information regarding the locations among all of the(More)
