Psychometry with Wechsler preschool and primary scale of intelligence(WPPSI)for 203 preschool children was conducted and the influence factors on their intelligence were investigated.
Use WechslerIntelligenceScale for children-Chinese Revised ( WISC -CR) to test every child and calculate the score of every branch scale and of total intelligence quotient.
To explore the relation between the Cognitive Assessment System(CAS) and the Wechslerintelligencescale for testing children, WISC-CR and CAS are taken in survey on 37 mildly retarded children.
