Aspirin Effects on Emotional Reactions

Study Overview
=================
Brief Summary
-----------------
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.

Design Details

Primary Purpose: Basic Science
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: Note. 135 of an originally intended 200 participants had been enrolled at the time of cessation of research activities due to COVID-19 research closures. Therefore, the intended sample was increased to 270 to allow comparison between pre-COVID and post-COVID participants.
Masking: Double

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Emotional Reactivity | Changes in self-reported evaluations of valence on a 1 to 7 scale and felt reactions to emotional images on a 1-7 scale. | 1.5 hours | 
| Memory | 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. | 1.5 hours | 
| Risk-Taking | We will measure the adjusted average number of pumps on the Balloon Analogue Risk Task. | 1.5 hours | 

Secondary Outcome Measures

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