This research lab, also known as "The Twin Play Lab," at Southern Illinois University is headed by Dr. Lisabeth DiLalla, a developmental psychologist at the SIU School of Medicine, and is home of the Southern IL Twins/Triplets and Siblings Study (SITSS). There are several research projects underway at the Lab, all of which are described at the "Research" link. The SITSS primarily focuses on preschoolers, with various projects encompassing the development of peer interactions and parent-child interactions from preschool through adolescence.
