Observational Study of Psychomotor Development in Children Born in France to Parents Born in Sub-Saharan Africa.

"The BSID-4 is a test that evaluates three areas of child's development, divided into three scales:~* The Motor Scale, which includes the fine motor and gross motor subtests;~* The Cognitive Scale, which consists of items assessing sensorimotor development, object exploration and manipulation, concept formation, memory, and other primary functions from which the child's reasoning abilities emerge;~* The Language Scale, which includes the receptive communication and expressive communication subtests.~The administration of the BSID-4 involves the standardized delivery of items. The BSID-4 standardization does not specify a fixed order for administering the scales: depending on the child's temperament and spontaneous interest, the examiner adapts the order in which the motor, language, and cognitive scales are administered."
