Priming Global and Local Processing of Composite Faces: An EEG Study
摘要
Abstract
In prior research,it has been shown that,using the composite-face illusion and the Navon patterns,the global/local level processing of the Navon patterns influenced the holistic processing of faces within a trial.The composite-face illusion reflects the difficulty to ignore one half (e.g.,bottom) of a face when the two aligned halves are incongruent.However,the neural mechanism supporting this effect remains unknown.Since a functional hemisphere asymmetry exists for the global versus local processing,with the left hemisphere (LH) and right hemisphere (RH) tunes to the local and the global processing,respectively,we predicted that the priming effect might be related to the modulation of the relative involvement of the LH and the RH.Here in the present study,we tested this hypothesis by comparing the alpha band (8-12 Hz) activity in the EEG recorded at posterior right and posterior left hemisphere sites while participants processed the global/local level of Navon patterns.We found that the global versus local processing modulated the composite-face illusion,however,the alpha band activity exhibited significantly stronger activities in the RH than in the LH in both priming levels.These results imply that the priming effect is not due to the modulation of the relative involvement of the LH and the RH.关键词
