Figure 1.

Experimental setup for a Spanish trial in the scripted confederate dialogue task. The top panel shows what the child saw on the computer screen. Text (translated below) is included for demonstration purposes only; the child only saw the scenes and a video of the partner. The bottom panel shows sample responses from the child, pushing the correct button in the guessing phase and producing a cross-speaker code-switch in the description phase. Guessing phase translation: The lady is bringing books to the school. Can you find this picture? Description phase translation: Your turn! Tell me about your picture, and I'll try to find it.
