Abstract

The purpose of the study was to find whether there were differences in cortisol awakening response (CAR) between a neutral day and an exam day in a group of female students and to explore possible relationships between CAR, self-reported affect, and exam performance. A group of 25 female students took samples of their saliva using Salivettes at the moment of waking and after 30 min. They then described their affect using the PANAS scale. Measures were taken twice: three days before an examination and on the day of the examination. The level of free cortisol in saliva samples was determined using enzyme immunoassay. The integrated volume of cortisol (CARauc) was significantly higher on the day of the exam than on the neutral day. There were also significant differences in affect, with negative higher and positive lower on the exam day, but correlations between cortisol measures and self-reported affect were low and not significant. A negative relationship between integrated volume of cortisol (CARauc) and exam performance was also found. Anticipated exam stress caused a significant increase in CAR in female study participants when compared to a neutral day, but only in the case of integrated volume of cortisol over the waking period (CARauc). The negative relationship between this measure and exam performance can be explained by attributing CARauc to negative expectations concerning the anticipated exam.
