Abstract: Objective To explore the design of word-picture matching semantic judgment task based on Chinese high frequency nouns and further explore the way to apply the task in a functional magnetic resonance imaging (fMRI)/event-related potential (ERP) study.Methods The materials, stimuli and procedure of the word-picture matching semantic task were provided. Then, a healthy subject for the pilot study was included. In the pilot study, fMRI and ERP data of the subject were collected during the word-picture matching task. The fMRI and ERP data were analyzed to test the feasibility of the word-picture matching task in an fMRI/ERP task.Results The results of fMRI analysis showed an increased activity in the right middle frontal gyrus under the word-picture presenting condition compared with the "+" presenting condition. In addition, fMRI analysis showed an increased activity in the right middle temporal gyrus in the word-picture mismatching condition compared with the word-picture matching condition. The results of ERP analysis showed an increased activity in the left frontal/temporal area in the word-picture matching condition and an increased activity in the right frontal area in the word-picture mismatching condition.Conclusion Language associated brain regions can be identified in the fMRI/ERP research based on the word-picture matching task described in this article, which indicated that the task is effective in exploring language processing mechanism in the brain.
