Bigelow, Maclean, and Proctor (2004) measured 1-year-old infants' play with and without their mother. They coded for four play levels: exploratory, inappropriate relational, appropriate relational, functional. Describe their results based on the data in the table. The numbers refer to mean percentage of time infants engaged in each type of play in the alone and mother conditions. What do these results suggest about the role of parents for children's play? How does this fit with Vygotsky's idea of a zone of proximal development?
