Amsterdam coffee-shop study explores the effects of cannabis on eye-witness memory

This study breaks new ground, but it’s not without some issues – for instance, the realism of recruiting coffee-shop patrons came at the expense of experimental control. There was no random allocation to conditions, for example, and the researchers didn’t have an accurate measure of their participants’ levels of intoxication. Vredeveldt and her team recommend that future research strive for greater experimental control, and they said it would be useful to find out whether the adverse effects of cannabis on recall dissipate once a witness sobers up. —Effects of cannabis on eyewitness memory: A field study Christian Jarrett (@Psych_Writer) is Editor of BPS Research Digest
