Epigenetic theory (Erikson) Erikson's epigenetic theory depicts personality development as a passage through eight sequential stages of ego development from infancy through old age. By contrasting DNA methylation age (estimated age) with chronological age, one can define measures of age acceleration. Age acceleration can be defined as the difference between DNA methylation age and chronological age. Alternatively, it can be defined as the residual that results from regressing DNAm age on chronological age. The latter measure is attractive because it does not correlate with chronological age. A positive/negative value of epigenetic age acceleration su… knee length shorts high waisted
