Physical activity behaviour displays temporal variability, and is influenced by a range of
dynamic psychological processes (eg, affect) and shaped by various co-occurring events …

The aim of this chapter is to (a) provide a broad didactical treatment of the first-order
stochastic differential equation model—also known as the continuous-time (CT) first-order …

Drawing on dynamical systems theory, we investigated whether within-persons-detected
early-warning signals in momentary affect preceded critical transitions toward lower levels of …

The present multi-study work presents a new self-report measure of meaning in life in the
context of situational life experiences. Study 1 presents the development of the Situational …

Intensive longitudinal studies are becoming increasingly popular because of their potential
for studying the individual dynamics of psychological processes. However, measures used …

Science is permeated by complexity. In biology, systems such as insect colonies, flocks of
birds, or ecosystems exhibit extremely complex behavior. For example, ant colonies …

Psychological researchers currently lack guidance for how to evaluate the practical
relevance of observed effect sizes, ie whether a finding will have impact when translated to a …

Computational models of affect dynamics are ubiquitous. These models are appropriate for
either exploring intensive longitudinal data or testing theories about affect dynamics. In this …

How long does a treatment take to reach maximum effect? Is the effect maintained or does it
dissipate or perhaps even reverse? Do certain sorts of people respond faster or stronger …

The principle of dynamical similitude—the belief that the same behavior may be exhibited by
very different systems—allows us to use mathematical models from physics to understand …
