Abstract

The study is on the effects of entertainment media on physiological and psychological indicators of stress. The concept of stress is considered to play a key role in the explanation of the effects of media use on aggression, academic performance, and health. Two types of media (television and video games) and violent versus nonviolent content were compared. Differential effects on physiological measures (heart rate [HR], heart rate variability [HRV], cortisol, salivary alpha-amylase [sAA]) and subjective experience were expected. Study participants consisted of 98 boys, aged 11 to 14. Physiological stress reactions were higher for video games than for television with regards to HR and HRV. Violent content had greater effects on physiological stress than nonviolent content, when measured in terms of sAA, cortisol, and HRV. Violent content, in general, was rated as being more stressful but also more enjoyable. The results underline that certain types of media use are associated with subjective and physiological indices of stress.
