The results shown in this graph indicate that there is no cultural gender difference in the expression of humor or laughter. However, there is difference in what all cultures believe humor is. This information is important because it explains why something is important to one culture and not another. The authors agree when they mention “in Japan, unlike the United States, humor is not considered an important coping tool. The American media praises the use of humor [regardless of occupation], especially when applied to situations of stress and illness” (as cited in Ofra Nevo and Baruch Nevo 2001 p. 153). In summary, all cultures have their own way (reason) of expressing laughter, but no less, all cultures express humor or laughter at the same rate. You might ask: how did the different perspective of laughter arise? The answer is simple, our behavior was shaped by observing speech before we could walk and talk. Childhood BehaviorIt is often said that human personalities resemble their behavior as children. Studies have shown a strong correlation with how they will behave in the future (resemble adult behavior). However, before babies come into the world, they are immediately taught what to do and what not to do. As researchers Malastesta and Haviland state, “children develop the ability to modulate their emotional expression as they grow” (Malatesta and Haviland 1986). According to Malatesta and Haviland “several studies of early mother-infant interaction suggest that young children are exposed to modeling and instrumental learning conditions during face-to-face play with their mothers; these conditions presumably constitute the very first opportunities to learn the display rules. , R.
