The present tutorial proposes to use concepts of physics and mathematics to help
behavioral scientists to use differential equations in their studies. It focuses on the first-order …

Studying the time-related course of psychological processes is a challenging endeavor,
particularly over long developmental periods. Accelerated longitudinal designs (ALD) allow …

Although many studies have unequivocally demonstrated the promise of understanding
resilience to adversity and characterizing the consequences if stress is unabated, needed …

People show stable differences in the way their affect fluctuates over time. Within the general
framework of dynamical systems, the damped linear oscillator (DLO) model has been …

Second-order linear differential equations can be used as models for regulation since under
a range of parameter values they can account for a return to equilibrium as well as potential …

Self-regulating systems change along different timescales. Within a given week, a
depressed person's affect might oscillate around a low equilibrium point. However, when the …

Studies have used the latent differential equation (LDE) model to estimate the parameters of
damped oscillation in various phenomena, but it has been shown that correct, non-zero …

This article proposes a dynamical system modeling approach for the analysis of longitudinal
data of self-regulated homeostatic systems experiencing multiple excitations. It focuses on …

In his target paper, Hopwood proposes the expansion of the Big Five framework beyond the
conventional range of personality features to cover (a) their maladaptive extremes …

Bipolar disorder affects about 1% of the world population and presents a serious problem for
affected individuals in their attainment of educational and other societal goals. Although …
