Laughter is associated with positive affect and social adequacy and is strongly correlated with the perception of a contribution to health given by a type of laughter. According to the researchers, the data received from the investigations revealed an interesting pattern. The findings suggest that young adults, compared to older participants, viewed loud laughter as more healthy and less controlled. Older, but not younger, participants indicated that social appropriateness is an important attribute of health-promoting laughter. Both groups indicated that positive emotion was an important attribute. In summary, the types of laughter perceived as most beneficial by the older group can be described as gentler, gentler and less active; Young adults' preferences are for greater volume and movement. There have been many changes in the social norms that govern the types of humor and responses to humor that are acceptable. (The Journal of Psychology, Mahony, Burroughs, & Lippman p. 179) Mora-Ripholl hypothesized that it is necessary to discriminate between laughter variables, since many analyzes of humor have used a humorous stimulus, for example a comedy film, to determine the effect of “humor” on a health-related outcome, and others categorically examine the effects of laughter on these findings. Still others explore different ways to test a sense of humor in an attack to analyze whether a higher score on a sense of humor scale is associated with certain health outcomes. (Mora-Ripoll pag.
