Respiratory dynamics during laughter.
Lung and chest wall mechanics were studied during fits of laughter in 11 normal subjects. Laughing was naturally induced by showing clips of the funniest scenes from a movie by Roberto Benigni. Chest wall volume was measured by using a three-dimensional optoelectronic plethysmography and was partitioned into upper thorax, lower thorax, and abdominal compartments. Esophageal (Pes) and gastric (P...
متن کاملPatterns of laryngeal electromyography and the activity of the respiratory system during spontaneous laughter.
Laryngeal muscle electromyography (EMG) and measures of the behavior of the respiratory system have been made during spontaneous laughter in two groups of subjects. The smaller group also had a direct measure of tracheal pressure during this behavior. Laryngeal adductors such as the thyroarytenoid (TA) and lateral cricoarytenoid (LCA) exhibited brief high-amplitude bursts of activity, at a rate...
متن کاملA study of laughter and dissociation: distinct correlates of laughter and smiling during bereavement.
Laughter facilitates the adaptive response to stress by increasing the psychological distance from distress and by enhancing social relations. To test these hypotheses, the authors related measures of bereaved adults' laughter and smiling 6 months postloss to measures of their (a) subjective emotion and dissociation from distress, (b) social relations, and (c) responses they evoked in others. D...
متن کاملStudy of changes in glottal vibration characteristics during laughter
Laughter in speech has been studied mostly relying upon the spectral representation like formants and harmonics derived from the short-time spectrum. Significant changes appear to take place in the characteristics of glottal source of excitation during the production of laughter, but these changes have not been explored much. In this study, we examine the changes in the glottal vibration charac...
متن کاملPhysiologic evidence for the interpersonal role of laughter during psychotherapy.
The role of laughter during psychotherapy is poorly understood. This study examined 10 unique sessions of psychodynamic psychotherapy with digital videotape and simultaneous measures of skin conductivity (SC) from patients and therapists. Independent observers coded laugh episodes using published criteria. Observers identified 167 laugh responses. Of the 119 patient laughs, 91 (76.5%) were pati...
