Abstract

Schemata enhance memory formation for related novel information. This is true even when this information is neutral with respect to schema-driven expectations. This assimilation of novel information into schemata has been attributed to more effective organizational processing that leads to more referential connections with the activated associative schema network. Animal data suggest that systems consolidation of novel assimilated information is also accelerated. In the current study, we used both multivariate and univariate fMRI analyses to provide further support for these proposals and to elucidate the neural underpinning of these processes. 28 Participants (5 male) over-learned fictitious schemata for seven weeks and then encoded novel related and control facts in the scanner. These facts were retrieved both immediately and two weeks later, also in the scanner. Our results conceptually replicate previous findings with respect to enhanced vmPFC-hippocampus coupling during encoding of novel related information and point to a prior knowledge-effect that is distinct from situations where novel information is experienced as congruent or incongruent with a schema. Moreover, the combination of both multi- and univariate results further specified the proposed contributions of the vmPFC, precuneus and angular gyrus-network to the more efficient encoding of schema-related information. In addition, our data provide further evidence for more efficient systems consolidation of such novel schema-related and potentially assimilated information.
