Milton is an 8-year-old. according to harter's research, what is the single most important aspect of milton's life that will determine his sense of self-worth? physical attractiveness positive regard from parents and peers socioeconomic status of his parents athletic ability

I believe the answer is: Positive regard from parents and peers
According to the research, most individuals would most likely develop a personal standard to determine self-worth when we're between 14-30 years old. For small children like milton, the source of self-worth would most likely come from the acceptance from the people near him. (friends and family)
