This study aims to understand how serotonin affects learning and decision-making in healthy individuals. The research involves the use of escitalopram, a medication that influences serotonin levels in the brain, and a placebo. Escitalopram belongs to a group of medications commonly used to treat depression, though this study focuses on its effects in healthy people.
The study will examine how the medication affects participants’ ability to make decisions and learn from their experiences. Participants will receive either escitalopram tablets or placebo capsules by mouth. The medication will be taken for a period of up to 24 weeks, with a maximum daily dose of 20 mg of escitalopram.
During the study, participants will complete various behavioral tasks and questionnaires to measure their decision-making abilities. The tasks will assess how quickly and accurately participants respond to different situations. The study uses a controlled approach where some participants receive the active medication while others receive the placebo, allowing researchers to compare the effects of escitalopram on learning and decision-making processes.
