Abstract:  Evaluated cardiovascular, hormonal and mood changes induced by the view of a violent or, in random order, neutral movie in 20 healthy young women (aged 25 ±2.6 yrs old). Prior to watching the movie, a basal blood sample was taken, and following the movie, Ss were asked how they felt about the movie and completed a bipolar self-rating scale. Results indicate that emotional arousal was associated with a significant increase in heart rate, systolic blood pressure and significant changes in self-evaluated mood states. β-Endorphin, adrenocorticotrophic hormone, epinephrine and growth hormone showed a significant increase during emotional arousal, with a significant interaction mood-time. Cortisol increased significantly during the violent movie. The data evidence the existence of neuroendocrine changes associated with the defense mechanism and aroused by movie violence and conflictual situations.
