Things to know:
The variables MomIntersubjectivity and DadIntersubjectivity record the scores for moms and dads as they are playing separately with their 4-year old children using a set of random toys. Intersubjectivity refers to the idea that the parent and child are on the same page while playing, working together to complete a task.
The variable DadChallenging record the scores for dads as they are playing with their 4-year old children using a random set of toys. Challenging play refers to the idea that parents challenge their children to think outside the box with novel toys, and teach them new ways of using familiar toys.
Research Question 1: do moms and dads differ in their level of Intersubjectivity during free play with their 4-year old children?
Research Question 2: do dads differ in their level of intersubjectivity and challenging play during free play with their 3-year old children?
