Learning And Developmental Disabilities Educational Neuropsychology Research (LADDER) Lab Welcome to Drexel University’s Learning And Developmental Disabilities Educational Neuropsychology Research Lab (LADDER). Our research focuses on how children with neurodevelopmental disorders and typical development think and learn as well as how the brain develops in these groups. We use three primary methods to learn more about child cognitive (thinking) and brain development. Children complete one-on-one testing with carefully trained researchers in our child-friendly laboratory at Drexel University. The types of tests children complete include things like: Puzzles to look at problem solving skills Block design to examine visual and spatial processing skills Language tests to evaluate knowledge of word meanings and grammar Academic achievement tests to measure reading and math skills Caregivers also complete questionnaires about their child’s behavior and development in the home. This helps us learn a lot about how children function every day in the real world. Children complete MRI scans so that we can get detailed pictures of the developing brain. (We are not currently completing MRI research, but we may begin to do this research again in the future).
