Priming, 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-...
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 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 کاملNeural Response Suppression Predicts Repetition Priming of Spoken Words and Pseudowords
An important method for studying how the brain processes familiar stimuli is to present the same item on more than one occasion and measure how responses change with repetition. Here we use repetition priming in a sparse functional magnetic resonance imaging (fMRI) study to probe the neuroanatomical basis of spoken word recognition and the representations of spoken words that mediate repetition...
متن کاملNeural 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...
