OverviewAI-generated summary
Parker A. Williams studies the effects of cannabidiol (CBD) on anxiety and emotional reactivity in humans. Current research includes a double-blind, randomized placebo-controlled trial investigating CBD's impact on worry and anxiety in individuals with high trait worry. Other work examines how sleep deprivation affects the ability to reappraise negative situations, with studies looking at both acute and repeated CBD administration in this context. Williams has a publication record of nine papers, with 49 citations, and an h-index of 3. Key collaborators include Ellen W. Leen‐Feldner, L. Riley Gournay, Morgan L. Ferretti, and Annamarie Stehli Nguyen, all from the University of Arkansas at Fayetteville, with whom Williams has co-authored multiple publications.
