The purpose of the work is to verify and describe the fluctuations or circadian, weekly and annual rhythms of the "attention" behaviour in 4, 5, and 6 year old children in one same school. Attention is measured in terms of "dedication" of child when performing an habitual school task and/or a cross out task. The parameters indicating "dedication" (attention), are : finishing the work, time invested, errors and omissions. The specific task lasting five minutes will be given five times a day distributed over similar intervals. This task as well as the usual school activity will be recorded in video during one whole week (from Wednesday to Wednesday) and three times a year (one every school term)
