[2] However, probabilistic epigenesis differs from Waddington’s model as it relies much more heavily on the potential developmental impacts of experience and environment and how they interact with an individual’s genes.
[2] Probabilistic epigenesis takes into account developmental, hormonal, environmental, neuropsychological, and genetic factors in order to explain various forms of behavior.
[3] In developmental psychology, probabilistic epigenesis is a theory of human behavior that assumes that different neural structures develop and activate either based on an individual's biology or interactions with their environment.
[3] It relies on the idea that there are multi-directional interactions between biological and psychological factors, meaning probabilistic epigenesis is a non-hierarchical model of understanding development.
[4] In other words, this means that the extrinsic factor of socioeconomic class can cause an individual to be less physically capable of handling stress and heavy workloads than someone born into a wealthier environment.
[1] “Nature versus nurture,” a term coined by Francis Galton in the late 1800s, was an early and simple way of explaining human behavior.
