Henry Otgaar The interesting question herein is how it is possible that children and adults adopt such implausible and negative events and develop false memories of them. This could result in people falsely accusing innocent people which in turn could end in legal consequences. Hence, my main research interest lies in the identification of mechanisms that contribute to the development of memory illusions. To tackle this issue, I adopt a multifaceted approach in which I study the development of memory illusions by using different memory paradigms (DRM paradigm, implantation paradigm, misinformation paradigm).
