Summary of data and sampling.
Fig 1.
Levels of periodicity in the temporal expression of the 73 psychometric variables at period 24-h.
The label of a category has size proportional to the percentage of variance explained in the four years fluctuations of the indicator by the profile of diurnal variation.
Fig 2.
Profiles of diurnal variation of the 73 psychometrics variables.
Fig 3.
Leading factors behind the Diurnal Variation Profile of the 73 psychometric categories.
The first leading factor (F1) and the second leading factor (F2) are shown separately. The profiles that contribute positively to the factors are plotted in red and displayed in the box above the x-axis (F1+ and F2+). The profiles that contribute negatively are plotted in blue and displayed in the box below the x-axis (F1- and F2-). The label of a profile has size proportional to the magnitude of its loading on the factor. The two leading factors are plotted in their respective scales for comparison (F1F2). The x-axis indicates the hour.
Fig 4.
Scatter of the 73 psychometric variables against the two orthogonal factors.
The profile of variation of each variable is mapped to the embedding spanned by the two leading factors, F1 (x-axis) and F2 (y-axis). The size of a label is proportional to the magnitude of the largest loading score in the embedding. We have listed the broader meta-processes on the left of the image with different colours, and size relative to the average size of the individual variables that compose them. Marker words (sunrise, sunset, midnight) which are known to peak at specific times were added to guide reading.

Mappings of the two types of thinking identified against the 73 psychometric variables.
The colours indicate the loading scores of the 73 categories onto F1 and F2.

Diurnal variations of the first leading factor (left) and second leading factor (right) by each day of week.
The x-axis indicates the hour.

Comparison between the variations of posemo, anger, sadness, and the two leading factors.
The x-axis indicates the hour.
