The Child Development Laboratory is one of the laboratories at PsiTra. It provides facilities for students at PsiTra, especially those related to Developmental Psychology, as a lab for research and observation. The lab is equipped with facilities for children and infants, such as toys and storybooks. The room is very comfortable for children to engage in activities due to its spaciousness, air conditioning, and attractive colors. What's interesting is that the toys in this lab have been donated by PsiTra students, showcasing their creative and innovative efforts using recycled materials. Although this lab is more focused on Developmental Psychology students, it is also open to other students according to the activities that they want to conduct.
