Give one similarity and one difference between Jean Piaget's and Lev Vygotsky's views on cognitive development

Both theorists felt that children were active participants in their learning, stressed the importance of mentally challenging students, and believed that children can benefit cognitively as a result of social interactions. However, Piaget claimed that the self-exploration initiated by the child fueled cognitive development, while Vygotsky stressed that cognitive development occurs through social interactions. Vygotsky also stressed the importance of language development and the influence of culture on cognitive skills more than Piaget.
