A new model is presented that explains reaction time fluctuations in prolonged work tasks. The model extends the so-called Poisson-Erlang model and accounts for long-term trend effects in the reaction time curve. The model is consistent with Spearman's hypothesis that inhibition increases during work and decreases during rest. (TJH)

Lessons in values development were observed in classes of Dutch students, aged 10-15. A 22-item observation instrument was used to record the amount of classroom time spent on a particular category.
