2-1 Discussion: Nature vs. Nurture Endures DEV. PSYCH
The evolution of the field of developmental psychology has begun to trend toward a more holistic view of development, and this is evidenced by the theories of hereditary and environmental interaction. On the surface, these theories appear to be challenging the nature versus nurture controversy by acknowledging that each is necessary and integral to development. Upon closer review, we find that the controversy endures as each theory appears to favor one over the other within the theory. Select one of the following heredity and environmental interaction theories that you believe provides the most valid explanation for the interaction of nature and nurture, provide a brief explanation of the theory in your own words, and clearly state which side of the nature versus nurture controversy you believe is favored by this theory.
● The canalization principle ● The range-of-reaction principle ● Genotype/environment correlations

Textbook: Lifespan Development in Context: A Topical Approach, Chapter 2 This chapter provides a context for understanding the earliest stages of development while emphasizing the role of genetic and environmental variables in development. The concept of development as a continuum is reinforced through exposure to the hereditary environmental principles including canalization, range of reaction, and gene/environment correlation.
While reading, consider the following:
- What is typical/healthy development?
- What is atypical/unhealthy development?
- Is it possible that in each core conflict there is a continuum where each developmental issue can be placed?
- What is the role of developmental psychologists in assessing and intervening during these developmental periods?

Prenatal Development: Typical and Atypical Development
The field of mental health has traditionally faced opposition from the medical community, and it has often struggled to be validated as a legitimate science by medicine. The rift between these two fields may result in a bias against the biological and hereditary contributions to development by researchers and professionals in psychology. Many who choose the mental health profession find little interest in the exploration of complex biological processes. However, as the field of medicine continues to evolve, there is increasing evidence of hereditary and biological influences on behavior. For example, positron emission tomography (PET) scan technology has been used to confirm lower dopaminergic activity levels in adults with depression (Moriya et al., 2020). This highlights one of the realistic struggles that present as a nature versus nurture controversy in the field of development. The identification of a clear biological mechanism responsible for these diagnostic mental issues (nature) provides a possible causal explanation, yet the therapeutic interventions will likely continue to require traditional mental health treatment (nurture). As the field continues to evolve, we are witnessing efforts to acknowledge the contributions of nature as well as nurture.
Theoretical efforts to recognize the fact that both nature and nurture make significant contributions to human development have been labeled as hereditary and environmental interaction theories. The heredity versus environment movement represents a key turning point in the nature vs. nurture debate because of its emphasis on how biology sets the limits of our developmental traits and the role of environmental influences in determining how these traits are expressed. While the core controversy of nature versus nurture continues to provide a context for the examination of development, the hereditary and environmental interaction concepts establish that this is really a continuum. Professionals must utilize that continuum to understand the most effective means in which to assess and intervene in support of healthy development. For example, Down syndrome is a genetic disorder that affects many areas of functioning, and while we acknowledge that a great deal of medical and biological intervention will be necessary, we understand that the ability to function emotionally and socially for the individual and his or her family may require mental health intervention.
Prenatal development presents as a high-risk phase of development in which many genetic and environmental influences can threaten an individual’s health. The field of teratology is devoted to understanding agents implicated in the causes, mechanisms, and patterns of abnormal development. These agents are referred to as teratogens. Teratogens present as environmental influences that can disrupt development, and they can take the form of illicit drugs (cocaine, heroin), toxic substances in foods or the environment (pesticides, cleaning agents), air pollution, extremes of heat and humidity, and even common viruses and bacteria. Kuther (2023) describes key principles that account for the observed effects of teratogens to include the period of exposure, the amount of exposure, individual differences in susceptibility and the complicated effects of teratogens. Health promotion in regard to the examination of exposure to teratogens may be one of the most influential areas in which psychological professionals can impact development in the earliest phases of life. Even over-the-counter, prescription, and herbal supplements may pose a risk if they are not accounted for during prenatal development.
Module Two presents an opportunity to examine the nature versus nurture controversy at the earliest phases of development. Through increasing our awareness that the nature versus nurture controversy is truly a continuum, we can begin to effectively utilize this continuum to examine developmental concepts for effective assessment and intervention. While understanding prenatal periods sets the foundation for our examination of development, understanding the risks and threats at this early stage of development will assist in defining the role of mental health professionals—a role that is called upon to define the difference between what is considered normal versus abnormal development. The developmental psychologist seeks to determine what is considered normal and healthy to identify when atypical development is present, and this sets the foundation for identifying causes as well as interventions.

Overview
Your active participation in the discussions is essential to your overall success this term. Discussion questions will help you make meaningful connections between the course content and the larger concepts of the course. These discussions give you a chance to express your own thoughts, ask questions, and gain insight from your peers and instructor.
Directions
For each discussion, you must create one initial post and follow up with at least two response posts.
For your initial post, do the following:
- Write a post of 1 to 2 paragraphs.
- In Module One, complete your initial post by Thursday at 11:59 p.m. Eastern.
- In Modules Two through Ten, complete your initial post by Thursday at 11:59 p.m. of your local time zone.
- Consider content from other parts of the course where appropriate. Use proper citation methods for your discipline when referencing scholarly or popular sources.
For your response posts, do the following:
- Reply to at least two classmates outside of your own initial post thread.
