Neural Basis of Repetition Priming during Mathematical Cognition: Repetition Suppression or Repetition Enhancement?
We investigated the neural basis of repetition priming (RP) during mathematical cognition. Previous studies of RP have focused on repetition suppression as the basis of behavioral facilitation, primarily using word and object identification and classification tasks. More recently, researchers have suggested associative stimulus-response learning as an alternate model for behavioral facilitation...
متن کاملRepetition suppression and repetition priming are processing outcomes.
Abstract There is considerable evidence that repetition suppression (RS) is a cortical signature of previous exposure to the environment. In many instances RS in specific brain regions is accompanied by improvements in specific behavioral measures; both observations are outcomes of repeated processing. In understanding the mechanism by which brain changes give rise to behavioral changes, it is ...
متن کاملRepetition Priming and Repetition Suppression: A Case for Enhanced Efficiency Through Neural Synchronization.
Stimulus repetition in identification tasks leads to improved behavioral performance ("repetition priming") but attenuated neural responses ("repetition suppression") throughout task-engaged cortical regions. While it's clear that this pervasive brain-behavior relationship reflects some form of improved processing efficiency, the exact form that it takes remains elusive. In this Discussion Pape...
متن کاملNeural response suppression, haemodynamic repetition effects, and behavioural priming.
Repeated stimulus processing is often associated with a reduction in neural activity, as measured by single-cell recording or by haemodynamic imaging techniques like PET and fMRI. These reductions are sometimes linked to the behavioural phenomenon of priming. In this article, we discuss issues relevant to theories that attempt to relate these phenomena, concentrating in particular on the interp...
متن کاملPriming, response learning and repetition suppression
Prior exposure to a stimulus can facilitate its subsequent identification and classification, a phenomenon called priming. This behavioural facilitation is usually accompanied by a reduction in neural response within specific cortical regions (repetition suppression, RS). Recent research has suggested that both behavioural priming and RS can be largely determined by previously learned stimulus-...
