The construct of humor in humans is a topic of great intrigue. It is generally accepted that humor has a stress-moderating effect in humans (Abel and Maxwell, 2002), but to what degree and in what instances does this effect apply? For example, Yovetich, Alexander, and Hudak (1990) studied the effect of humor on threat-induced anxiety and stress. Results show that humor led to a general decrease self-reported anxiety as well as increased smiling activity, but that heart rate was not lowered. Does humor only affect cognition, and if so, what other types of stress (besides threat-induced anxiety) will cause the same effect? Also, it has been shown that one’s own perception of humor can be easily influenced and manipulated (Olson 1992). Is humor, again, only a function of malleable human cognitive processes?
