The aim of this project is to study children’s language development by looking at how they understand particular types of sentences. The study focuses on development in children between the ages of 4-6 years-old. We will show your child a friendly picture on a computer screen. The pictures are Sesame Street themed and feature Ernie and his friends doing different activities. One of us holds a hand puppet who makes comments about the pictures. Your child will be asked to talk to the puppet and tell him if his comment about the picture sounds good or sounds silly. The study will take about 15 minutes to complete. The study will be conducted by Lauren Winans, UCLA Linguistics doctoral candidate. This study is supervised by Professors Nina Hyams, PhD and Jessica Rett, PhD. Any questions about the study should be directed to Lauren Winans (lauren.winans@ucla.edu).
