Unstructured and Structured Dyadic Tasks

Dyadic Task	Description
Unstructured: Get-to-know-you	Peers were seated at a table facing each other and briefly introduced to each other by the experimenter. The experimenter immediately announced he/she needed to find some paperwork and would be back shortly. Children were left alone to interact freely for 5 minutes.
Structured: Cooperation Task	Each Cooperation task lasted 5 minutes once dyads were given instructions.
	Lego Puzzle: Experimenter gave a Lego car model to the BN peer, and all the necessary pieces to build the same model to the BI peer. The experimenter instructed the children to work together to recreate the car. A cardboard divider was propped on the table so that the BI peer could not see the built model, forcing the peers to work together under the BN peer’s directions.
	Etch-a-Sketch: The experimenter provided an Etch-a-Sketch toy and a sketch pattern. Children were instructed to work together to draw the pattern, with each child assigned to control only one knob.
