Abstract Researcher shave payed increasing attention to studies of the emotional effect on working memory, especially on the updating function of central executive system. In this paper, we discussed the effects of positive, neutral and negative emotions on updating of working memory. Sixteen subjects participated in this experiment, in which emotional pictures were firstly presented to evoke their three emotional states followed by 4 numbers running memory task. Results showed that the updating time in the positive state is significantly longer than that in the neutral state (Positive state: (1.016±0.338)s; Neutral state:(0.814±0.347)s, P<0.05), and the amplitude of N2 in parietal area was significantly smaller than that in neutral state. In the late period of working memory updating(400～1 000 ms), the energy in band 13～30 Hz decreased significantly, which was less than that in the neutral state. While no significant difference of updating time was detected between the negative state and neutral state. During the early updating(0～400 ms), the improvement of the energy in band 0～8 Hz was less than that in the neutral state. These results suggested that positive emotion impaired the updating of working memory, while no significant effect of emotion on the updating was observed in the negative states. This research provided experimental support for the improvement of the updating performance of working memory.
