| Research Abstract |
1) Influence of emotion-inducine film stimuli on autonomic response specificity
The present study investigated the autonomic response variables elicited during the viewing of video-taped stimuli selected to produce positive and negative emotions in the viewer. Neutral footage was also used. Fifteen participants successively viewed three 10-minute films and blood pressure (BP), electrocardiogram, fingertip temperature, respiration rate were also measured throughout film sessions. The participants completed two questionnaires concerning provoked emotions after each film presentation. Cardiovascular responses decreased during positive and increased during negative emotion. Fingertip temperature increased during negative emotions but did not change during positive emotions. Based on the cognitive aspects of the film stimuli, the different cardiovascular patterns were explained by the stimulus intake-rejection hypothesis.

tensity.
Nine participants used a bicycle ergometer to exercise for 15-minute periods at 2 different intensities ; a comfortable self-established pace (CSEP) and 70% V0_2max. Frontal EEG was monitored prior to exercise and during exercise recovery. To evaluate emotional changes associated with exercise, questionnaires were completed prior to, during, immediately after exercise and during exercise recovery. The α-power spectrum of the frontal EEG was compared between F3 and F4. Both exercise at CSEP and 70% V0_2max intensity showed decreased anxiety immediately after exercise and during exercise recovery. Exercise at CSEP intensity was not hemispherically asymmetric prior to exercise and during recovery. Exercise at 70% V0_2max was not hemispherically asymmetric prior to exercise, however, the α2 power(9.5-11.5 Hz) of F3 was lower than that of F4 during 60-minute recovery. The left frontal α power spectrum, specially α 2, at 70% VO_2max would reflect increased positive emotions and decreased anxiety during exercise recovery. These results were discussed on the approach-withdrawal model of Davidson. Less
