To compare Piitsburgh sleep quality index ( PSQI) and β-band EEG power changes of the college students who received and did not receive imaginary working training, and to explore the specificity of imaginary working on the sleep quality regulation of the introverted and extroverted personalities. Methods College students were randomly divided into experimental group and control group according to the introverted and extroverted dimension by the ratio of 1 1. The experimental group received the intervention of imaginary working, while the control group did not receive any intervention. Both groups were intervened by three imaginary themes, and the data of Piitsburgh sleep quality index and β-band EEG absolute power were collected and compared between the two groups. Results After intervention, the Pittsburgh sleep quality index was improved. There was statistic difference between the introverted experimental group and the control group (P <0. 05), but there was no statistic diiference between the extroverted experimental group and the control group. In terms of the (3-band absolute power change, there was statistic diiference in FC4, C3, CP3, P3 leads between the introverted experimental group and the control group (P <0. 05), and there was statistic diiference in T4 and 01 leads (P <0. 01) ; besides there were statistic diiferences in F8, FT8 and C4 leads between the extroverted experimental group and the control group(P <0. 05), and statistic diiferences in FCZ lead(P <0. 01 ) . Conclusion Imaginary working could possibly improve the sleep quality of people with extroverted personality, and the training of imaginary working could improve the sleep quality of those with introverted personality.
