You answered this question with some helpful information but after reading what u put would the answer be how personality develops across the lifespan then?

Developmental psychologists study all of the following EXCEPT:

-What part of the brain is involved in the development of depression
- Smoking trends of adolescents
- Prenatal development
- Aging issues of the elderly
- How personality develops across the lifespan

Please go back and read Bob's answer again. He gave you such a big hint that it should be hitting you in the face.

I had a typo, I will correct it..

<smoking in teens is a development issue, they study that. What development psychologist studies brains...the realm of neurosugerons?>

Since the neurological aspects of depression are not related to any particular portion of the lifespan, this would be more in the realm of physiological psychology or clinical rather than developmental.

I hope this helps a little more. Thanks for asking.

Based on the options provided, the question asks which area developmental psychologists do not study. Let's examine each answer choice:

- "What part of the brain is involved in the development of depression": Developmental psychologists study how the brain develops and changes across the lifespan, including the development and impact of mental health disorders such as depression. So, this is an area that developmental psychologists do study.

- "Smoking trends of adolescents": Developmental psychologists are interested in studying various behaviors and trends that occur during different stages of development, including adolescence. So, this is an area that developmental psychologists do study.

- "Prenatal development": Developmental psychologists examine the stages of human development, including prenatal development, which refers to the development of the embryo and fetus during pregnancy. So, this is also an area that developmental psychologists do study.

- "Aging issues of the elderly": Understanding the changes and challenges that come with aging is an important area of study for developmental psychologists. So, this is another area that falls within their scope of study.

- "How personality develops across the lifespan": The development of personality is a key focus for developmental psychologists. They study how personality traits emerge and change over time. So, this is an area that developmental psychologists do study.

Based on the options provided, the answer is none of the above. Developmental psychologists study all of these areas, including how personality develops across the lifespan.
