This study addresses the basic structure of playfulness in adults from a psy- cho-lexical approach and its relationship with the sense of humor. Using items derived from a corpus analysis of written accounts in the German language, five factors were derived (N = 195); that is, (a) cheerful-engaged; (b) whimsical; (c) creative-loving; (d) intellectual; and (e) impulsive. Their contents strongly overlap in comparison with an earlier study using this approach. However, the correlation of the intellectual component with two current measures of adult playfulness was low, and the impulsive component was not correlated with these measures. The question arises as to whether these aspects exist only as components in the implicit psychological and linguistic theories. The sense of humor was most strongly related with the cheerful-engaged factor while some “humor skills” were particularly related to other factors; for example, finding humor under stress with the intellectual component. This study helps toward a better understanding of the basic structure of playfulness in adults.
