Substances or agents that can disrupt the normal development of a fetus during pregnancy, leading to birth defects or developmental abnormalities, are a significant concern in developmental psychology. These harmful agents can include certain drugs, alcohol, environmental pollutants, viruses, and even high levels of stress in the pregnant individual. For instance, exposure to alcohol during prenatal development can result in fetal alcohol spectrum disorders (FASD), characterized by a range of physical, behavioral, and cognitive deficits.
Understanding the impact of these developmental disruptors is crucial for promoting healthy prenatal development and preventing potential harm to the developing child. Awareness of these agents allows for informed decision-making by expectant parents and healthcare providers, leading to preventative measures and interventions. Historically, the recognition of the damaging effects of certain substances, such as thalidomide in the mid-20th century, highlighted the critical need for rigorous testing and careful consideration of potential risks during pregnancy.
