Research has shown that early childhood may be the most important life stage for brain development.A babys brain is about one quarter the size of an adults.Scientists have found that babies brains develop in response to stimulation.Arouses senses such as sight, sound, touch, taste, and smell.Babies who are stimulated develop more quickly and have a more secure self-image.

Cognitive theories:
Piagets cognitive developmental theoryStresses conscious mental processesCognitive processes are influenced by biological maturation Four stages of cognitive development in childrenAssimilation and accommodation underlie how children understand the world, adapt to it, and organize their experiences
-
Preoperational Stage:
The child begins to represent the world with words and images. These words and images reflect increased symbolic thinking and go beyond the connection of sensory information and physical action.Formal Operational Stage
The adolescent reasons in more abstract idealistic and logical ways. Sensorimotor Stage:
The infant constructs an understanding of the world by coordinating sensory experiences with physical actions: progressing from reflexive, instinctual action at birth to the beginning of symbolic thought toward end of the stage.Concrete Operational Stage:
The child can now reason logically about concrete events and classify objects into different sets.Figure 2.31115 years of age through adulthoodBirth to 2 years of age2 to 7 years of age7 to 11 years of agePiagets Four Stages of Cognitive Development
