| Research Abstract |
The purpose of this study was to evaluate an affective process quantitatively using physiological responses. We conducted following three studies to clarify the relationship between emotional changes during watching an educational media and patterning of respiratory and cardiovascular responses.
Firstly, we developed a set of film clips that reliably elicit positive and negative emotions. After evaluating over 100 films, we selected some clips that elicited negative emotions (NEGA) and some clips that elicited positive emotions (POSI).
Secondly, we conducted one experiment concerning about the effects of emotional film clips upon respiratory and cardiovascular responses. Minute ventilation significantly increased for both POSI and NEGA. The mean blood pressure significantly increased in NEGA, whereas the heart rate significantly slowed in POSI. These results suggest that positive and negative emotions facilitate ventilation, and that positive and negative emotions elicit different responses in the cardiovascular system.
Finally, we also conducted an experiment to determine whether self-control of breathing can alter cardiovascular and psychological reactivity during emotions. The results suggested that self-control of breathing did not reduce subjective emotional responses but can be effective in altering cardiac parasympathetic inhibition during negative emotions.
