Factors affecting human growth and development B1 – The nature/nurture debate related to factors B2 – Genetic factors that affect development B3 – Environmental factors that affect development B4 – Social factors that affect development B5 – Economic factors that affect development B6 – Major life events that affect development
B1 – The nature/nurture debate related to factors Development across the lifespan is a result of genetic or inherited factors – Gesell’s maturation theory Development across the lifespan is a result of environmental factors – Bandura’s social learning theory Both factors may play a part – stress-diathesis model

Gesell’s Maturation Theory (Nature) Gesell noted that each child moved through the sequence of ‘norms’ or ‘milestones’ at their own pace. Maturation is the genetically programmed sequence of change we all go through in life. Gesell believed development is predetermined, with little influence from the environment. If a child experiences delayed development, then the problem is heredity not circumstances.

Bandura’s Social Learning Theory
Stress-Diathesis Model This helps to explain how stress caused by life events (nurture) can interact with an individual’s genetic vulnerability (nature) to impact on their mental well-being. Some people are born with certain genetic predispositions to a mental illness (diathesis) However, they may never develop the disorder if they do not experience stress in their life. Stressful events that could trigger the onset for those with a predisposition = family conflict, abuse, trauma, problems at school etc. Diathesis = a predisposition or vulnerability to mental disorder through abnormality of the brain or neuro-transmitters.
