| Abstract: | Earlier research on respiratory patterns indicates that they are sensitive to emotional processes. Abdominal and thoracic patterns were therefore used as predictors of laughter responses in 25 subjects participating in an entertainment situation. The abdominal respiratory body circumference changes (the abdominal amplitude) of the women predicted their laughter responses; the greater the abdominal amplitudes during the entertainment period, the more frequent and enduring were their laughter responses. No prediction was obtained by the respiratory patterns of men. The results suggest that respiratory patterns are sensitive indicators of laughter response habits in women only. The variability of tonus in the abdominal muscles was suggested to be of particular importance to the results, i. e. great variability yields frequent and enduring laughter responses in women. |
