These three developmental theories contribute to the understanding of Jack’s abilities and can be helpful in the planning of interventions to prevent a disruption in Jack’s continued growth and development. However, there are also limitations to be considered. For example; Erikson’s strength is the application from infancy to late adulthood but his theories were directed more for male individuals over females and were unable to be strictly tested.

These three theorist allow Jack’s current stage of development to be pinpointed. However, there is more to what is happening with Jack than just a mark on a scale. We know there will be many influences in his biopsychosocial growth whether nature or nurture related, these risks call for intervention. One identified risk is to his physical health due to exposure of toxins during a sensitive period in his development. Environment as well as genetic will be consider in the following section. Developmental Concepts- Biological The Interaction of Heredity and Environment – Most of what is known of Jack’s prenatal development is normal. However, his case lists environmental factors which impose a risk to him. Jack had exposure to a teratogen agent, which is a substance considered toxic to the developing fetus and places a child at risk to be born with a birth defect or other damage. Specifically, he was exposed to nicotine
