title: Nonlinear dynamical models in psychology are widespread and testable.
abstract: Comments on the article by Fredrickson and Losada (see record 2005-11834-001). Fredrickson and Losada's claimed connection between positivity ratios in human interactions and the Lorenz chaotic attractor and the extensive critique thereof (Brown, Sokal, & Friedman, December 2013) lead me to offer several remarks about nonlinear dynamical systems (NDS) models in psychology that would-be researchers should understand if the goal is to move the science forward.
