FIGUEIREDO, Sandra; HIPOLITO, João  and  TOMAS, Cátia. The relationship between chronotype and times of cognitive performance of the Portuguese child. Psic., Saúde & Doenças [online]. 2018, vol.19, n.1, pp.42-49. ISSN 1645-0086.

The deepening of knowledge about the consequences of sleep routines in children's daily life, especially at school level, will have outputs not only in structuring learning throughout the day (with a positive effect on academic results and consequently on self-esteem and sense children's competence), but also in terms of health promotion. The present study aims to analyze the routine sleep/wake behavior of school-age children, with the objective of examining the relationship between chronotype and attention fluctuation in the same tasks administered at different times of the day. In this cross-sectional study, a set of specific tests of care for Portuguese children of the 1st Cycle and between the ages of seven and ten are in use. After the Chronotype Questionnaire was applied, the sample was divided according to two categories of chronotype - morning and evening - to evaluate the effect of synchrony (interaction between the chronotype and the time of day in which performance is observed). Results are expected to confirm the synchrony effect, ie, the positive relationship between the morning type and the optimized performance in tasks administered in the morning in contrast to the afternoon period. On the one hand, the data will help families and children develop and maintain healthier sleep habits. On the other hand, to guide education professionals regarding the adequacy of school schedules for specific tasks and skills development.

Keywords : attention; chronotype; cognitive performance; synchronization effect; time of day.
