Group-level correlogram of correlation coefficients according to the time lags among emotion, fatigue, and pain.

Notes: Cross-correlation analyses of the time series of emotion, fatigue, and pain conducted by participant; the 20 acquired correlation coefficients in each set (emotion and fatigue, emotion and pain, as well as pain and fatigue) were averaged among the 20 participants and shown in the correlogram. The threshold was ±0.96, which is the threshold level for cross-correlations with 15 time points. (A) Group-level cross-correlation analysis of emotion and fatigue by time. (B) Group-level cross-correlation analysis of emotion and pain by time. (C) Group-level cross-correlation analysis of pain and fatigue by time.
