Early Phase Testing Of Functional Imagery Training As An Intervention For Anxiety, Jackie Andrade, D. J. Kavanagh, Carly Bowditch, Emily Mackriel, Emily Ravenshill, Amy Sime, Eleanor Trumfield, Jessica Watts, Jon May

School of Psychology

Cognitive models hypothesize a role for motivated behaviour in anxiety disorders, with safety behaviours leading to exaggerated threat appraisals and increased anticipatory anxiety. Based on the Affective Imagery Theory of Motivation, we propose that increasing motivation for engagement behaviours will reduce motivation for safety behaviours through competition for limited capacity cognitive resources supporting motivational imagery. We hypothesise that imagining successful engagement will reduce anxiety directly, and through promoting subsequent engagement. We present preliminary evidence that functional imagery training (FIT), an intervention that develops and teaches motivational imagery, reduces anxiety. FIT was delivered to undergraduates with anxiety in one session lasting …

Research outputs 2022 to 2026

Background: Globally, coffee and tea are consumed extensively, potentially providing neuroprotection through anti-inflammatory and antioxidative stress effects. Objective: This study aimed to investigate associations between coffee and tea intake and cognitive function. Methods: In a longitudinal prospective cohort study, dementia-free (n = 8715; age range 60.0–85.2 years) older adults from the UK Biobank self-reported coffee and tea intake over the previous year; ‘never’, ‘moderate’ (1–3 cups/day), or ‘high’ (≥4 cups/day). Participants completed cognitive assessments at ≥2 timepoints (mean of 9.11 years). Results: Those ‘never’ consuming coffee and ‘moderate’ coffee consumers (β = 0.06, p = 0.005; β = 0.07, p <  0.001, respectively), as well as ‘moderate’ tea consumers and ‘high’ tea consumers (β = 0.06, p = 0.009; β = 0.06, p = 0.003, respectively) had slower fluid intelligence decline. Additionally, those ‘never’ consuming coffee and ‘moderate’ coffee consumers had a slower increase in pairs matching errors (β = −0.05, p = 0.022; β = 0.05, p = 0.013) compared to ‘high’ consumers. Conclusions: ‘Moderate’ coffee, and ‘moderate’ and ‘high’ tea intake may be a protective factor against cognitive decline. Randomized controlled trials are required to establish causal relationships leading to evidence-based recommendations regarding benefits of coffee and tea intake.

Uinta Basin Snow Shadow: Impact Of Snow-Depth Variation On Winter Ozone Formation, Michael J. Davies, John R. Lawson, Trevor O’Neil, Seth N. Lyman, Karlee Zager, Tristan D. Coxson

Bingham Research Center

After heavy snowfall in the Uinta Basin, Utah, elevated surface ozone occurs if a cold-air pool persists and traps emissions from oil and gas industry operations. Sunlight and actinic flux from a high-albedo snowpack drive ozone buildup via photolysis. Snow coverage is paramount in initiating the cold pool and driving ozone generation. Its depth is critical for predicting ozone concentrations. The Basin’s location leeward of the Wasatch Mountains provides conditions for a precipitation shadow, where sinking air suppresses snowfall. We analyzed multiple years of ground-based snow depth measurements, surface ozone data, and meteorological observations; we found that ozone levels track …
