RESULTS

Database of 4 and 7 years old

children (Bigras, 2009-2011).

Screen time (ST) comprises sedentary activities

WISC-IV Cognitive abilities WIAT-II

142 children

RESEARCH QUESTION

1 hour or less of ST per day More than 1 hour of ST per day

* • Verbal comprehension • Perceptual reasoning • Working memory • Processing speed • Reading test • Math test

ST affects children’s cognitive

development

Limiting ST to 1 hour a day in

preschool-aged children

Sociodemographic

factors incomeFamily

Mother’s repo! questionnaire

Does limiting ST to 1 hour a day in

preschool-aged children ensure optimal

cognitive abilities at school age?

Preschoolers’ ST is associated with ce!ain cognitive abilities at school age.

Limiting preschoolers’ ST to 1 hour a day is a valid way of contributing to optimal cognitive development in the long term especially for…

ST decreases family literacy activities and real and contingent interactions between children and adults.

WHY?

Difference between ST activities Passive ST activities

Active and interactional ST activities that demand more cognitive effo!.

WHY?

Psychometric tests
