Which of the following is a critique of Jean Piaget's theory of cognitive development?

Option 1 : Language plays a very important role in cognitive development of children.

Jean Piaget, a Swiss psychologist, has made a systematic study of cognitive development in his theory that is categorized into four stages. 

• He observed his children and their process of making sense of the world around them and developed a model of how the mind processes new information encountered.

Piaget considered that cognitive development is independent of language and thought determines language.​

• According to Piaget, thought emerges first, and; language becomes the intermediary providing the means by which later concepts and conceptual thinking are furthered.
• He emphasizes that "Thought not only determines language but also precedes it".
• According to him, language and cognitive development doesn't base on social interaction. Although Vygotsky explains as language and thought can be developed much by social interaction.

Hence this is a critique of Piaget on language development but it is considered as language and thought are developed by direct interaction with society.

Hint According to Vygotsky:

• Language is essential for cognitive development.
• Language plays a powerful role in shaping individuals' thoughts.
• By acquiring; language, a child modifies its higher mental functions.
• In the initial stage, thought & language are independent but merge at around two years of age.
