Overview

The aim of this study is to determine whether the drug aspirin has effects on emotional reactivity, emotional memory, and risk-taking behaviors.

Detailed Description

The goal of this study is to determine if aspirin (acetylsalicylic acid) alters emotional reactions to emotion evoking pictures as well as memory for them. Using a double-blind parallel arm study, participants will receive either placebo or a pain-relieving dose of aspirin (500mg). One hour later they will complete 30 minutes of tasks. This will include ratings of emotional pictures and memory for them. The paradigm is similar to previous experiments done in this lab using other cyclooxygenase inhibitors: ibuprofen and acetaminophen (Durso, Luttrell, & Way, 2015; Psychological Science, https://doi.org/10.1177/0956797615570366). Risk taking on the Balloon Analogue Risk Task will also be assessed. Participants will be healthy young adult males at Ohio State University.

Interventions

  • Drug: Aspirin 500 MG
    • Single 500mg aspirin capsule.
  • Drug: Placebo
    • Single 500mg placebo capsule.

Arms, Groups and Cohorts

  • Placebo Comparator: Placebo
    • Single dose of a 500mg placebo tablet.
  • Active Comparator: Aspirin 500MG
    • Single dose of a 500 mg aspirin tablet.

Clinical Trial Outcome Measures

Primary Measures

  • Emotional Reactivity
    • Time Frame: 1.5 hours
    • Changes in self-reported evaluations of valence on a 1 to 7 scale and felt reactions to emotional images on a 1-7 scale.
  • Memory
    • Time Frame: 1.5 hours
    • Changes in memory for emotional pictures. After rating the images, the participants will be shown them again as well as new pictures and asked to indicate whether they have seen the picture before or not.
  • Risk-Taking
    • Time Frame: 1.5 hours
    • We will measure the adjusted average number of pumps on the Balloon Analogue Risk Task.

Secondary Measures

  • Individual Differences
    • Time Frame: 1.5 hours
    • Self-reported political ideology will be examined as a moderator of the self-reported ratings of the images as well as memory for them.
