The (TSST) is a standard and widely used research assessment procedure that is used to reliably induce stress in human research participants. The TSST uses situations where people think they are being socially evaluated during an interview for a job. Participants are told they are competing with other people for this job, and their task is to convince interviewers that they are the best person for the job. Participants are told they have to prepare a speech, and complete a math challenge in their head.
