Phase II of the study will begin with an entirely new group of subjects. Again, a standardized IQ test will be administered and those subjects with IQs ranging from 95-115 will be utilized for the study. Those subjects chosen to participate will return at a later date, and equal numbers of males and females will participate. Upon their return to the testing site, all subjects will first be subjected to a cognitive task that is designed to induce moderate and relatively equal levels of stress in both males and females. Subjects will be directed to complete the task as quickly and as accurately as possible. (Finding the appropriate task may also be conducted in Phase I.) Immediately following the cognitive task, subjects will be exposed to the medium of humor that was selected for in Phase I. Upon finishing the viewing/reading of the humorous item, subjects will complete scales for general mirth acquired from the item. These scores were the same in Phase I of the study, so differences reported in Phase II may be attributable to the effects of the preceding cognitive task.
