OverviewAI-generated summary
Ellen W. Leen‐Feldner, Professor and Vice Chair at the University of Arkansas at Fayetteville, investigates the effects of various substances and conditions on human psychological states, particularly anxiety and fear. Her research frequently employs double-blind, randomized placebo-controlled trial designs to rigorously assess these effects. Recent work has focused on the impact of cannabidiol (CBD) on worry, anxiety, and nicotine withdrawal severity, with studies examining its effects in individuals with high trait anxiety and during acute e-cigarette abstinence.
Leen‐Feldner's research also explores other aspects of psychological well-being and physiological responses. This includes investigating the perceived effects and use patterns of cannabis products, such as those containing hexahydrocannabinol. Additionally, her work has examined the relationship between tiredness and emotional arousal in adolescents during hyperventilation tasks, as well as the experimental effects of acute sleep deprivation on affect and avoidance behaviors. She has collaborated with researchers including L. Riley Gournay, Matthew T. Feldner, Morgan A. Hill, and Morgan L. Ferretti on shared publications.
With a career marked by significant scholarly output, Leen‐Feldner has authored 114 publications, accumulating over 3,499 citations and an h-index of 36. She is recognized as a highly cited researcher, underscoring the impact of her contributions to the field.
