One of the main focuses of modern psychological humour theory and research is to establish and clarify the correlation between humour and laughter. The major empirical findings here are that [[laughter]] and humour do not always have a one-to-one association. While most previous theories assumed the connection between the two almost to the point of them being synonymous, psychology has been able to scientifically and empirically investigate the supposed connection, its implications, and significance.

In 2009, Diana Szameitat conducted a study to examine the differentiation of emotions in laughter. They hired actors and told them to laugh with one of four different emotional associations by using auto-induction, where they would focus exclusively on the internal emotion and not on the expression of laughter itself. They found an overall recognition rate of 44%, with joy correctly classified at 44%, [[Tickling|tickle]] 45%, [[schadenfreude]] 37%, and taunt 50%.<ref name="Szameitat2009">Szameitat, Diana P., et al.

This brings into question the definition of humour, then. If it is to be defined by the cognitive processes which display laughter, then humour itself can encompass a variety of negative as well as positive emotions. However, if humour is limited to positive emotions and things which cause positive affect, it must be delimited from laughter and their relationship should be further defined.
