The role and mechanism of emotional words in knowledge integration

Combining the separation sentence paradigm and the priming paradigm, this study explored the role of emotions in integrating relevant memory fragments by controlling the type and valence of emotional words in sentences. A total of 34 participants were included. The experiment is a three factor mixed design consisting of 2 (emotional word types: emotional label words, emotional load words) x 2 (activation methods: semantic activation, emotional activation) x 3 (emotional word valence: positive, neutral, negative). Among them, the type and initiation mode of emotional words are inter subject variables, the valence of emotional words is intra subject variable, the dependent variable is the accuracy of the integrated test, the hit rate of the main fact recognition, the discriminative power d 'and the judgment standard β, and the amplitude of event-related potentials N400, P1 and LPC..
