EXPLORA stands for EXperimental PsychoLOgical Research on Autism, an interdepartmental research group within the FPES, led by prof. dr. Roeljan Wiersema (Department of Experimental Clinical and Health Psychology). With our studies we aim to better understand autism and its related features. For this, we use a multimethod approach (quantitative including neuroscientific methods, but also qualitative), whereby we aim to give space to the voice of experienced experts as well. The research focuses mainly but not exclusively on adults. Attention is also paid to related conditions such as ADHD.
