I have written an essay which I believe will be both interesting and informative for those who study psychology and neurology. Although it may appear to cover only a small field, it has implications for the fields of physiology, psychology, neurology and sociology.
Laughter as an exapted displacement activity: the implications for humor theory and neuropsychology and neurophysiology in general.
As It seems I am not allowed to post URLs, if you are interested, Google:
"anewtheoryoflaughterandhumor - basilhughhall" with the punctuation marks and select the article that is on google sites. It is the first one up on my computer.
