Language and Thought: A Comparison of Piaget and Vygotsky
Piaget proposed that cognitive development precedes language development, while Vygotsky disagreed, arguing that language significantly influences thought. For Vygotsky, language is crucial for shaping thought and regulating cognitive behavior, suggesting that thought cannot exist without language.
In early infancy, Vygotsky noted that speech (like babbling) and thought (such as reaching for objects) develop separately. However, around age two, speech and thought begin to interact and influence each other. As they merge, thought starts to adopt verbal traits, and speech becomes a clearer expression of thought.
Moreover, Vygotsky and Piaget held different views on children's self-talk during play. Piaget referred to this as egocentric speech, believing it did not aid cognitive development and simply reflected a child's self-centeredness, which fades by the end of the preoperational stage. In contrast, Vygotsky called it private speech, seeing it as a critical step in learning self-regulation. Initially, children's behavior is guided by external speech from others. As they strive for independence, they use private speech to direct their actions, which eventually evolves into inner speech around ages six or seven. This development is essential for cognitive growth and typically reflects thought processes.
Research indicates that children aged two to five perform tasks better when they use self-talk rather than remaining silent (Winsler et al., 2007). Additionally, as children engage in private speech, their communication skills with others also improve. Winsler and colleagues encourage adults to pay attention to children's private speech, as it offers valuable insights into their thinking.
