Fig. 1.

An example of a state space grid depicting a sequence of emotions of a parent-child dyad. The size of the circles is proportional to the duration of time each emotion is expressed, and the arrows reflect the changes between emotions. The light grey area on the grid is the positive affect region, the dark grey area on the grid is the negative affect region, and the white cell on the grid is the mutual neutral affect region. Separate grid were created for mother-child and father-child dyads
