Evolution of the concept of light. Panel (a) shows the trajectory of the concept light around concepts commonly associated with light (blue points) and concepts reflecting chaotic social scenario (red points). Crisis period starts at point and finishes in point . Grey points show the trajectory of light during the control period (3 months after crisis). Standard deviation around the two principal components of points in control trajectory is shown by the ellipse, showing that during crisis the light concept moves towards chaotic-associated words. Panel (b) shows the mean TSS of the concept of light for both groups (G1: light concepts, blue line; G2: crisis concepts, red line). Mean TSS between light and all words in G2 (chaos) showed a positive correlation with min temperature (black line).
