Interactions between evolutionary psychologists and developmental systems theorists have been largely antagonistic. This is unfortunate because potential synergies between the two approaches remain unexplored. This article presents a method that may help to bridge the divide, and that has proven fruitful in biology: dynamic optimization. Dynamic…

The relationship between complexity and usefulness can be captured by a U-shaped curve. This comment explores that relationship. Complexity may be useful for one of the main aims of developmental psychology (causal inference) but not for another (description of developmental phenomena). Currently, developmentalists conduct complex analyses that…

Analyzes suicide in terms of a dynamic model of changes in suicidal tendencies over time. Suggests that minor fluctuations may incite rapid development toward suicide or inhabit suicidality. Notes that this method of analysis and developmental modeling is applicable to other phenomena involving development in complex human behaviors in an open…

Discusses Mishara's use of phrase space analysis to chart the developmental dynamics of suicide. Contends that developmentalists should concern themselves with mental ontology, especially epistemic questions, in order to advance understanding of the development of the human mind. Considers the affinity of interactivism with a dynamic systems…
