Emotional face expressions recognition in childhood: developmental markers, age and sex effect.

Recognizing emotional face expressions in others is a valuable non-verbal communication and particularly relevant throughout childhood given that children's language skills are not yet fully developed, but the first interactions with peers have just started. This study aims to investigate developmental markers of emotional facial expression in children and the effect of age and sex on it. A total of 90 children split into three age groups: 6-7 years old (n = 30); 8-9 years old (n = 30); 10-11 years old (n = 30) took part in the study.
