Intrinsic motivation, on the other hand is inherent in the interest value of the task itself. Motivational flow is the experience of intrinsic motivation, which is in turn the result of the levels of challenge and skill involvement for a particular task. The level of flow is predictive of the amount of time a person will spend in that task, and it is though to form a basis for an individual's time allocation between occupational and leisure activities. The logs provided a time series of several hundred points for each participant, which were each subjected to nonlinear dynamical analysis through nonlinear regression. Principal results were that flow was chaotic for all participants.
Nonlinear models fit the data better than linear counterparts.
Nonlinear models were stronger for people who spent more time at paying jobs. Evidence for individual differences in dynamical character were uncovered. With kudos to my co-authors, Elizabeth Johnson and Mark Rieke. A stochastic mathematical model of arterial pressure recordings was developed to provide insight into and information about the baroreceptor reflex response. Using the model, the strength of the baroreceptor response can be assessed for an animal given its arterial pressure recording.
