Brief Summary

The goal of this work is to address increasing concerns about young children's digital media exposure and language outcomes by testing how the times course of word learning unfolds in digital environments and the cascading impact of digital media on vocabulary outcomes. The findings will have important implications for understanding when and where optimal word learning from media can occur.

Outcome Measures

Primary Outcomes (3)

• Accuracy on selecting the target item on referent selection

  Children's choices on each trial of the task will be measured. Correct responses are those to the target (prompted) item - for referent selection, this is the item asked for in the prompt (e.g. shoe, dog)

  1 minute

• Accuracy on selecting the target item on retention

  Children's choices on each trial of the task will be measured. Correct responses are those to the target (prompted) item - for retention, this is the item asked for in the prompt.

  5 minutes

• Accuracy on selecting the target item on novel noun generalization task

  Children's choices on each trial of the task will be measured. Correct responses are those to the target (prompted) item - for generalization this will be considered as the shape-matching item (and not choosing a color or material match)
