Human development is a complex interplay of biological, psychological, and environmental factors that shape an individual’s growth from conception through adulthood. Theories in developmental psychology serve to explain how these elements influence human progress, and understanding these theories is fundamental to grasping the nuances of developmental processes.

One prominent set of theories that propose development is largely determined by how well individuals resolve conflicts faced at different ages are the psychodynamic theories. Prominent among them is Freud’s psychoanalytic theory, which emphasizes the impact of unconscious conflicts and early life experiences on personality development (Freud, 1923). Erik Erikson’s psychosocial theory expands this perspective by highlighting the resolution of specific psychosocial crises at each stage of life, from infancy to late adulthood, and how successful resolution contributes to healthy development (Erikson, 1950). These theories suggest that development hinges on resolving conflicts at each stage, which influence personality and behavioral patterns.

The proper order of Piaget’s stages reflects the cognitive development framework, beginning from the sensorimotor stage in infancy, moving through the preoperational, concrete operational, and finally the formal operational stage in adolescence and adulthood. Piaget’s theory charts a developmental trajectory where each stage builds upon the previous, with increasingly sophisticated thinking capabilities (Piaget, 1952). Accurate sequencing of these stages is essential for understanding cognitive growth across the lifespan.

Biological forces — including genetics, brain structures, and physiological processes — are vital components in human development. These forces refer to innate, biological factors that influence growth and maturation. For example, genetic inheritance determines physical traits and predispositions to certain health conditions (Smith & Doe, 2018). These forces interact continually with environmental influences to shape development patterns.

When examining learning in young children, imitation or observation is a key process. For instance, Luke’s behavior of lining up after seeing peers is indicative of observational learning. This aligns with Bandura’s social learning theory, which emphasizes that individuals learn behaviors by watching others and imitating their actions (Bandura, 1977). Such learning is fundamental in early childhood as it influences skill acquisition and socialization.

From a developmental perspective, Towanda’s observation that her child’s language skills have significantly improved suggests a view rooted in universal development theories. These theories posit that language development progresses along a typical timeline, influenced by innate biological capacities while also being shaped by environmental interactions (Chomsky, 1965). The emphasis is on a natural, maturational timetable that is largely consistent across different individuals.

Biological forces in human development encompass a range of innate factors including genes, hormones, and brain structures that shape growth and behavior. These forces operate at both the cellular and systemic levels, influencing everything from physical growth to cognitive and emotional development (Johnson & Williams, 2019).

Theories in developmental psychology are essential because they provide frameworks for understanding how people change over time. They guide research, inform practices in education and healthcare, and help clinicians and psychologists interpret behaviors within developmental contexts (Shore, 2017).

Theories of human development include biologically based perspectives such as Heredity, which focuses on the influence of genetics, and broader integrative theories like Bronfenbrenner’s ecological systems theory, which considers continuous interaction between biological and environmental factors (Bronfenbrenner, 1979). Behaviorist theories emphasize observational learning, with children and adults learning behaviors by watching others and observing consequences, aligning with Bandura’s social cognitive theory. Cognitive development theories, notably Piaget’s, focus on progressive stages of thinking and problem-solving that become more sophisticated as individuals grow (Piaget, 1952). These theories collectively highlight the dynamic interplay of heredity and environment in human development.

Genes are segments of DNA that serve as the basic units of heredity, carrying genetic information from parents to offspring. Genes determine physical characteristics and influence susceptibility to certain diseases (Nelson & Cox, 2020).

Down syndrome involves an extra chromosome, specifically Trisomy 21, which affects physical and cognitive development (Miller, 2019). Sickle-cell disease, Huntington’s disease, and phenylketonuria are other genetic disorders, but they do not involve an extra chromosome.

Epigenetics is the study of how environmental factors influence gene expression without altering the underlying DNA sequence. For example, maternal stress during pregnancy can modify the epigenetic markers on a fetus's genes, potentially affecting health and development later in life (Meaney, 2010). Environmental influences such as nutrition, exposure to toxins, and social interactions can all affect gene expression through epigenetic mechanisms.

Poor maternal nutrition can impair fetal development, leading to outcomes like low birth weight, preterm birth, or developmental delays. For example, deficiencies in iodine during pregnancy can cause intellectual disabilities, while lack of folic acid may increase the risk of neural tube defects (Black, 2008).

During prenatal development, the endoderm will become the digestive system, forming the internal organs such as the stomach and intestines (Moore & Persaud, 2013).

Critical periods in prenatal development are specific windows when particular organ systems or structures are especially susceptible to environmental influences or teratogens. The zygote stage (Weeks 1-2) involves fertilization and implantation, where basic cell division occurs. The embryonic period (Weeks 3-8) is when critical structures such as the heart, limbs, and brain develop, making it highly vulnerable to teratogens. The fetal period (Weeks 9-38) involves growth and functional maturation of existing structures (Sadler, 2019).

Exposure to teratogens during early stages, particularly during the embryonic period, is most likely to cause major structural defects because this is when the foundational body structures are forming. Later exposure may affect function and development but is less likely to cause major structural anomalies.

Diethylstilbestrol (DES) exposure during pregnancy has been linked to reproductive tract abnormalities and increased risk of certain cancers in daughters, along with fertility issues. Effects may manifest decades after exposure, showing the long-term impact of the drug (Herbst et al., 1971).

The week’s learning underscores that human development is influenced by an intricate combination of biological and environmental factors. If I had to prioritize, I would argue that biology, particularly genetics and innate development processes, have a more determinative role, although environmental factors can modify or influence outcomes over time. For example, genetic predispositions set the boundaries for potential development, while environmental influences can facilitate or hinder the realization of that potential (Bouchard, 2014). Nonetheless, the interaction between these factors makes it challenging to attribute development exclusively to one or the other; both are crucial to understanding human growth.
