Professor Jennifer Rennels’ Baby & Child Rebel Lab at UNLV is seeking families with 5- to 10.5-month-old infants, and 4-6-year-old children to participate in research studies that examine how children learn and think about people in their social world. During your visit, we will record your infant/child watching videos of different types of faces while sitting with you. Children also complete short tasks designed to be engaging. These studies last approximately 3-15 minutes, with an average visit to the lab lasting about 20-30 minutes. Babies receive a UNLV baby rebel t-shirt, onesie, or bib, and children receive a small gift for participating. Some studies provide compensation.
