Description: This study examined the impact of cannabis use on false memory production. The Deese/Roediger-McDermott (DRM) paradigm was used to induce false memories. In this paradigm, participants study word lists that are associatively related to a non-presented word, termed the critical lure. In a later memory test, true recognition rates and false alarm rates toward critical lures and unrelated items are assessed. Memory performance was compared between three groups: Regular cannabis consumers who were acutely intoxicated (n=53), regular cannabis consumers who were sober (n=50), and cannabis-naïve participants (n=53). The participants were approached in Dutch coffeeshops (cannabis outlets) and cafes and asked to participate in our study. After collecting general information on their cannabis use, they were subjected to the DRM test. The materials for the DRM paradigm and the questionnaires used can be found in this folder.
