According to Piaget, the sensorimotor stage spans which approximate age range?

1. Table 3.2 lists Piaget's four cognitive stages and their approximate ages. 2. Sensorimotor is shown first with the age range zero to two years. 3. Preoperational follows from two to seven years. 4. Concrete operational runs seven to eleven, formal operational eleven to fifteen. 5. Hence the sensorimotor age range is zero to two years. _Source: syllabus Psychology Ch 3 "Human Development", p. 48, Table 3.2 Piaget's Stages_
