Using the parametrized relativistic particle we obtain the noncommutative Snyder space-time. In addition, we study the consistency conditions between the boundary conditions and the canonical gauges that give origin to noncommutative theories. Using these results we construct a first order action, in the reduced phase-space, for the Snyder particle with momenta fixed on the boundary. Pacs: 11.1...

In this comment, I first highlight the contributions of Robinson-Cimpian, Lubienski, Ganley, and Copur-Gencturk (2014) in particular and a more interdisciplinary approach in general for the subdiscipline of developmental psychology. Second, I identify some historic methodological foci of psychology and encourage Robinson-Cimpian et al. to consider these possibilities. Finally, I end with my per...
