[Object permanence in children with neurological and psychomotor disorders].
The aim of this research was to investigate whether the development of object permanence is an available sign of the cognitive development in infants with psychomotor handicaps. Subjects consisted of 5 males, ranging in age from 12 to 33 months, with handicaps as a result of perinatal brain injury. Four were preterm infants. All of the children received psychomotor treatment. Their stage of object permanence was assessed using traditional (B-L) and non traditional test (U-H). (The children's performances on the U-H scales have an "Intrinsic validity"). Four children achieved the first stages of the development of object permanence. The acquisition of object permanence was delayed in comparison with the age-appropriated time, but it may be considered adequate in comparison with the "developmental age" (B-L). One children with severe mental and motor disorders solved no task, the findings suggest that the children with psychomotor handicaps may gain the concept of object permanence and that psychomotor treatment may assist them in the development of the concept. This performance is not age-dependent. So the acquisition of the concept of object permanence may be considered an accurate and sensitive tool for the follow-up of the sensorimotor development in the handicapped children.
