 Repetition priming has also been associated with attentional processes, stimulus expectation and episodic memory.Research into repetition priming has been used to investigate the nature of mechanisms underlying the behavioural effects of rapid learning.In utilizing measures of "repetition suppression", the putative neural correlate of repetition priming, and measuring changes in the neural response associated with changing the presented stimuli, researchers are attempting to index regions and their processing biases along perceptual, conceptual and response dimensions.
