4Imagine:You are playing with a six-month-old infant and suddenly leave the room to answer the telephone.You take a four-year-old child’s small cup of juice and empty it into a larger cup.While trying to settle a fight over the TV between a seven-year-old and a 12-year-old, you flip a coin. The seven-year-old loses.

15Identifying Substages Juan accidentally pushes his stuffed toy and it makes a noise as it is squeezed. Juan laughs and does it again, and again, and again.Linnea is sitting in her highchair.

42Challenges to Piaget’s Theory Underestimated children’s capabilitiesFailed to distinguish competence from performanceDoes cognitive development occur in stages?Does Piaget “explain” cognitive development?Little attention to social and cultural influences
43Strengths of Piaget’s Theory Vivid and detailed description of cognitive developmentHighlight interactive nature of cognition and environmentChildren are active constructors of knowledge
44Vygotskythe child and the environment work together to shape cognition in culturally adaptive waysdevelopment proceeds through social interaction and entails gradual internalization of cultural knowledge and processes for manipulating thought
