Challenge and threat are independent of each other

Many people are familiar with a fear of examinations, very few would not at least be a little nervous before an oral presentation. The research team took a closer look at the physical and mental reactions before and during this kind of presentation. To do this, they asked 123 participants to talk about their suitability for their dream job in front of an examiner, who reacted neutrally. Before and after this presentation, saliva samples were taken from the people undergoing the test and the concentration of the stress hormone cortisol was determined. They also asked the participants questions, which provided information about whether they perceived the situation as threatening or challenging. The adjectives "confident," "hopeful" and "optimistic" represented a challenge, while "worried," "anxious" and "fearful" represented a threat.

"The perception of threat and the cortisol concentration increased during the presentation, while the perception of challenge decreased. Challenge and threat thus show opposite courses and can occur independently of each other," reports Nina Minkley. "Decreasing cortisol and reduced threat are associated with improved presentation performance." In particular, the perception of self-efficacy reduced the release of cortisol and led to the participants view the situation as a challenge rather than as a threat.

Possibilities for examiners

"This knowledge is particularly interesting as it highlights possible ways to reduce stress during oral examinations," says Nina Minkley. "For example, examiners could inform the examinees about the conditions and requirements of the presentation situation in advance in order to keep the initial perception of threat as low as possible." In addition, examiners could create a friendly and supportive atmosphere right at the beginning when those giving the presentations enter the room, respond more emotionally and give behaviour-based feedback.
