The sensorimotor stage is representative of the early-aged youth, from birth to age two. It is a period where the child begins to recognize basic mobility and hand-eye coordination as well as a variety of foundational mental representations accumulated through vision, touch, and motor conditioning. The preoperational stage is a period where more formal logic is developed, ranging between age two through seven, in which the child maintains rather egocentric behaviors and attitudes. It is in this stage where the youth maintains centric-style thinking, which is placing all of their focus and attention on a singular characteristic rather than thinking abstractly about various alternatives. Centration in this stage will often have a child stating that the volume of liquid in two similar beakers, when poured into a taller and more slender container, remains the same even though there was a transition. Thus, broader logic has not yet been developed.
The next stage is the concrete operational stage, appropriate for youths between seven and 12 years of age, where conservation is now understood, comprehending concepts of reversibility, the ability to classify objects based on common shapes and sizes, and the youth begins to reject their previous egocentric thought. The final stage is formal operations, occurring between the ages of 12 to late adolescence. This stage involves maintaining an understanding of abstract moral and ethical principles, where the child is able to reasonably determine potential consequences to an action, and where some egocentric behaviors and attitudes re-emerge as a product of identify formation.
Having provided a brief summation of the different stages, the one particular stage of development appropriate for more intensive examination is the concrete operational stage, the stage where egocentric behavior begins to diminish and where elementary logic begins to surface.
