which is often unsuccessful. It is also mentioned that these people may have an implicit feeling of negativity. So they use this humour as a means of hiding that inner negative feeling. In the study on humour and psychological well-being, research has concluded that high levels of adaptive type humour (affiliative and self-enhancing) is associated with better self-esteem, positive affect, greater self-competency, as well as anxiety control and social interactions. All of which are constituents of psychological wellbeing. Additionally, adaptive humour styles may enable people to preserve their sense of wellbeing despite psychological problems. In contrast, maladaptive humour types (aggressive and self-defeating) are associated with poorer overall psychological wellbeing, emphasis on higher levels of anxiety and depression. Therefore, humour may have detrimental effects on psychological wellbeing, only if that humour is of negative characteristics. Physiological effects Humour is often used to make light of difficult or stressful situations and to brighten up a social atmosphere in general. It is regarded by many as an enjoyable and positive experience, so it would be reasonable to assume that it might have some positive physiological effects on the body. A study designed to test the positive physiological effects of humour, the relationship between being exposed to humour and pain tolerance in particular, was conducted in 1994 by Karen Zwyer, Barbara Velker, and Willibald Ruch. To test the effects of humour on pain tolerance the test subjects were first exposed to a short humorous video clip and then exposed to the cold pressor test. To identify the aspects of humour which might contribute to an increase in pain tolerance the study separated its fifty-six female participants into three groups, cheerfulness, exhilaration and humour production. The subjects were further separated into two groups, high Trait-Cheerfulness and high Trait-Seriousness according to the State-Trait-Cheerfulness-Inventory. The instructions for the three groups were as follows: the cheerfulness group were told to get excited about the movie without laughing or smiling, the exhilaration group was told to laugh and smile excessively, exaggerating their natural reactions, the humour production group was told to make humorous comments about the video clip as they watched. To ensure that the participants actually found the movie humorous and that it produced the desired effects the participants took a survey on the topic which resulted in a mean score of 3.64 out of 5. The results of the Cold Press Test showed that the participants in
