Abstract
The aim of this study was to examine the influence exposure to video and/or sounds of nature on stress after a stressful event, and correlation between objective stress indicators, subjective stress indicators and neuroticism. The study included 105 participants, mostly students of psychology and phonetics at the University of Zagreb. Heart rate was used as an objective measure of stress, measured in regular intervals, while assessment of experienced stress before nad after the stressful event was used as a subjective measure of stress. Stress was induced by a stress-test consisting of a series of simple mathematical problems which were rapidly altering, while the participants were tasked with giving the solution to each problem aloud. After the stress test, the
participants, depending on the group, watched a video of waves on the shore with the accompanying sounds, a black screen with the sounds of waves, or black screen without
any sounds. A mixed-design analysis of variance showed no difference between groups.
Stress assessment given before the stress test did not correlate significally with any other variable except for the stress assessment given after the stress test, while stress assessment given after the stress test correlated positively with heart rate in 9 out of 12 points of measurment, higher neuroticism and female gender.
