We examined whether alternate systems compensate for deficient ones to process relations in amnesia. Transverse patterning (TP), a test of relating items to one another in memory, is reliably impaired in amnesia and has played a central role in testing hippocampal function. We facilitated successful TP in amnesia by providing familiar stimuli with(More)
This work examined whether semantically relevant schemas could facilitate learning in the transverse patterning (TP) task, which requires participants to learn the value of each stimulus in relation to the stimulus with which it is paired (e.g., A wins over B, B wins over C, C wins over A). Younger and older adults received the standard TP in isolation(More)
Transitive inference is a complex task, conducive to the use of multiple strategies. We investigated whether transitive inference accuracy can be improved by biasing strategy choice towards a proposition-based approach that relies on the extraction of relations among stimuli. We biased strategy choice by using familiar stimuli with known relations that tap(More)
It is well known that previous perceptual experiences alter subsequent perception, but the details of the neural underpinnings of this general phenomenon are still sketchy. Here, we ask whether previous experiences with an item (such as seeing a person's face) leads to the alteration of the neural correlates related to processing of the item as such, or(More)
Aging has been associated with a decline in relational memory, which is critically supported by the hippocampus. By adapting the transitivity paradigm (Bunsey and Eichenbaum (1996) Nature 379:255-257), which traditionally has been used in nonhuman animal research, this work examined the extent to which aging is accompanied by deficits in relational learning(More)
