The main objective was to further unravel the experience of motivation in an expert male skydiver by investigating: (1) his general experience of motivation and perception of the dangers of skydiving; (2) his pursuit of new challenges and learning new skills as factors in maintaining motivation; (3) evidence of a mastery-based confidence frame in his motivational experience. This was a unique case study informed by reversal theory. The participant’s perception of skydiving was that it was not a risky or dangerous activity and a primary motive for his involvement in skydiving was personal goal achievement. Maintaining control and mastery during skydiving was a key motivational element during his long career and pursuing new challenges and learning new skills was found to be important for his continued participation. Data indicated that his confidence frame was based on a telic-mastery state combination, which challenged previous reversal theory research findings and constructs.

ABSTRACT The age of a mutant gene is studied using the infinite allele model in which every mutant is new and selectively neutral. Based on a time reversal theory of Markov processes, we develop a method of mathematical analysis that is considerably simpler for calculating the various statistics of the age than previous methods. Formulas for the mean and variance and for the distribution of age are presented together with some examples of relevance to cases in natural populations.—Theoretical studies of the first arrival time of an allele to a specified frequency, given an initially monomorphic condition of the locus, are presented. It is shown that, beginning with an allele that has frequency p = 1 or an allele with frequency p = 1/2N, there is an initial lag phase in which there is virtually no chance of an allele with a specified intermediate frequency appearing in the population. The distribution of the first arrival time is also presented. The distribution shows several characteristics that are not immediately obvious from a consideration of only the mean and variance of first arrival time. Especially noteworthy is the existence of a very long tail to the distribution. We have also studied the distribution of the age of an allele in the population. Again, the distribution of this measure is shown to be more informative for several questions than are the mean and variance alone.
