Stages of Intellectual Development in Children The stages of intellectual development formulated by Piaget appear to be related to major developments in brain growth. The human brain is not fully developed until late adolescence or in the case of males sometimes early adulthood. We often expect children to think like adults when they are not yet capable of doing so. It is important that parents know what to expect from their child as they develop and to be sure that the expectations they may have for their child at a given age are realistic. Piaget's Stages of Cognitive Development Sensory Motor Period (0 - 24 months) | Developmental Stage & Approximate Age | Characteristic Behavior | Reflexive Stage (0-2 months) | Simple reflex activity such as grasping, sucking. | Primary Circular Reactions(2-4 months) | Reflexive behaviors occur in stereotyped repetition such as opening and closing fingers repetitively. | Secondary Circular Reactions (4-8 months) | Repetition of change actions to reproduce interesting consequences such as kicking one's feet to more a mobile suspended over the crib. | Coordination of Secondary Reactions (8-12 months) | Responses become coordinated into more complex sequences. Actions take on an "intentional" character such as the infant reaches behind a screen to obtain a hidden object. | Tertiary Circular Reactions (12-18 months) | Discovery of new ways to produce the same consequence or obtain the same goal such as the infant may pull a pillow toward him in an attempt to get a toy resting on it. | Invention of New Means Through Mental Combination (18-24 months) | Evidence of an internal representational system. Symbolizing the problem-solving sequence before actually responding. Deferred imitation. | The Preoperational Period (2-7 years) | Developmental Stage & Approximate Age |
