The quality of attention is not constant over the course of the day. This finding is well established for external cognitive tasks. Less documented is its expression in the domain of inner observation.
Data gathered by the Laboratory across several practitioners over periods of six months or more shows a stable correlation between the time of day and certain characteristics of observation. These correlations are individual in their precise configuration, but some patterns are recurrent.
Recurrent patterns
In the morning (first hour after complete awakening), observation tends toward clarity and neutrality. States are less affectively charged, easier to distinguish. This is generally the most productive window for delicate observations.
In the early afternoon, an attentional trough is observed in the majority of subjects. Observation loses in precision but sometimes gains in access to deeper layers — reduced vigilance also weakens defence mechanisms.
In the evening, states are more charged, more difficult to observe with neutrality, but often richer in information about underlying emotional patterns. This data has no prescriptive value — it has the value of a map. Each practitioner must build their own.
