Table 1 Some CRP textures and their meanings
Texture | Meaning |
|---|---|
Fading portions to the upper left and lower right corner | Data is non-stationary, i.e., data has slowly varying parameters |
Single and isolated recurrence points | Reflect random and strong fluctuations in the data but are not considered a unique sign of chance or noise |
Horizontal/vertical lines and rectangular clusters | Marks a time length which a state does not change or changes very slowly or the process is halted at a singularity in which the dynamic is stuck in paused states (called “laminar” or “trapped” states) |
Bands of white space | Indicate abrupt changes or transitions that may reflect an underlying state changes |
Two collaborators uninterruptedly looked at two different spots on the screen | |
Empty regions | The states within this period do not occur at any other times (e.g., states are unique or far from normal) |
Diagonal lines parallel to the main diagonal | Segment of one trajectory runs almost parallel to another segment (i.e., the trajectories visit the same region of the phase space at different times) |
Collaborators looked at the same spot on the screen continuously |
