The investigators will compare performance on a memory task between stressed and non-stressed participants. This memory task requires people to integrate knowledge across learning experiences (think: having to \"connect the dots\", draw inferences, and generalize your knowledge to new situations and scenarios). Cortisol, the brain's primary stress hormone, will be measured at multiple points throughout the study to measure stress levels. The investigators hypothesize that:\n\n1. Stress will disrupt performance on the memory task by interfering with memory processes that enable linking of related memories.\n2. Higher cortisol levels, which reflect a greater stress response, will relate to greater deficits in memory performance across participants.\n\nThis research has broad implications for understanding how stress impacts the ability to learn and retain new information, particularly in high-stress environments like schools and workplaces. Additionally, this work may provide insights into the cognitive difficulties experienced by individuals with psychiatric disorders, where stress can worsen memory and learning challenges.",null,[18,19],"Stress","Control Condition",[21,22,23,24],"acute stress","memory","memory integration","cognitive maps","INTERVENTIONAL","BASIC_SCIENCE",[28],"NA",{"count":30,"type":31},80,"ESTIMATED",[33,41],{"type":34,"name":35,"description":36,"armGroupLabels":37,"otherNames":39},"BEHAVIORAL","Acute Stress","Participants randomized to the acute stress condition will complete the Trier Social Stress Test (TSST), a validated experimental method for inducing acute psychosocial stress.
