This term comes out of the book 'Inside Jokes' by Hurley, Dennett and Adams and is derived out of the psychology of tickling. The only thing that you can do is to think that it will not work. Once you are laughing there is no way back. What I think about this term is rather positive but I have questions in the experimental usage of this term. Of course this book is meant as philosophy to defend their model. In their model they stress the positive side of what is found into mental space as something wrong. The covertness of the idea which I have earlier noted with the concept of sureness of attributions. Also the absence of real compassion is noted in the model. They state that humor is derived foremost from thought and not feeling. They use the term auto-supervision to explain our social culture in practice. Which is in itself pretty piecemeal. From this model they came to the concept of perceptual belief to show that some thoughtful element must lie within this laughing behavior in the end.
Something totally different but also with an aspect of thought is music. We are most of the time overstimulated by expectations. Music gives a way to deal with this in a pleasurable manner. David Huron has already described this in the book 'Sweet Anticipation'. How I see it, is that normal people are already overstimulated. But how is it when people are a bit thin in their head. I think this is about the same, but process is itself over-activated. It can't handle the energy inside. Probably this hasn't a function. I have this feeling when I don't eat enough, or when I stop smoking. Also when I am just thinking too much out of basis or real social contact. It isn't a perceptual belief, it is perception which leads to the realization you have to do it calmer down. That you have to rest in other words. It can lead to other behavior or even thoughts but this is not the same. Even if people recognize another body language, and label it as a sign of severe illness. It is speedy feeling. But at least it is so that your thoughts become more in tunnel-vision, less introverted and more extraverted, and less broad in general. It is also a feeling which is not pleasant, or agreeable. You have the feeling to be less in control. It is very frustrating.
