Semantic versus perceptual priming in fusiform cortex.
What is the nature of the representations of visual objects in the human brain? How abstract are these representations? Recently, Koustaal et al. have reported evidence of neural correlates of semantic priming in the left fusiform gyrus 1. They showed that when subjects see repeated presentations of pictures previously seen, or new pictures from object categories previously seen, there is a red...
متن کاملIn search of perceptual priming in a semantic classification task.
Four experiments tested for perceptual priming for written words in a semantic categorization task. Repetition priming was obtained for low-frequency words when unrelated categorizations were performed at study and test (Experiment 1), but it was not orthographically mediated given that written-to-written and spoken-to-written word priming was equivalent (Experiments 2 and 3). Furthermore, no p...
متن کاملPerceptual and semantic contributions to repetition priming of environmental sounds.
Repetition of environmental sounds, like their visual counterparts, can facilitate behavior and modulate neural responses, exemplifying plasticity in how auditory objects are represented or accessed. It remains controversial whether such repetition priming/suppression involves solely plasticity based on acoustic features and/or also access to semantic features. To evaluate contributions of phys...
متن کاملPerceptual Thresholds and Priming in Amnesia
The widely accepted idea that perceptual priming is intact in amnesia was challenged recently by the suggestion that perceptual identification (PID) thresholds are elevated in amnesia and that this impairment could mask a priming deficit by artificially inflating priming scores. The authors examined the PID thresholds of amnesic patients across a wide range of stimulus conditions and accuracy l...
متن کاملNeural mechanisms of visual object priming: evidence for perceptual and semantic distinctions in fusiform cortex.
Previous functional imaging studies have shown that facilitated processing of a visual object on repeated, relative to initial, presentation (i.e., repetition priming) is associated with reductions in neural activity in multiple regions, including fusiform/lateral occipital cortex. Moreover, activity reductions have been found, at diminished levels, when a different exemplar of an object is pre...
