| Popis: | The aim of present research was to investigate system organization of behavior dynamics which manifests in heart rate dynamics. The participants (n=30) described 24 images which in turn appeared on a computer screen. Having described an image, the participants evaluated emotional images by valence and arousal on 9-point scales, but not earlier than one minute after describing it. Heart rate was recorded during image description. Sample entropy of the heart rate irregularity was lower for images rated as negative with high arousal, as compared to neutral images in a group of participants whose ratings of negative and neutral images differed considerably. The received results allow us to suggest that higher emotionality characteristics are connected to temporary systems dedifferentiation. |
