Which theory suggests that viral infections during prenatal periods can lead to behavioral abnormalities?

The theory that suggests viral infections during prenatal periods can lead to behavioral abnormalities is known as the Viral Infection Theory. This theory posits that exposure to certain viruses during key developmental periods in the womb can disrupt normal brain development, potentially resulting in a variety of behavioral issues and psychological disorders later in life. Research has indicated that specific viral infections, such as the influenza virus or the rubella virus, may be linked to increased risks of conditions such as schizophrenia, autism spectrum disorders, and others.

This theory emphasizes the biological underpinnings of behavior and mental health, highlighting the importance of prenatal factors in the development of psychopathology. In contrast, other theories such as the Learning Theory focus on how behaviors are acquired and modified through experiences, Psychological Models explore mental processes and emotional responses, and Behavioral Genetics examines how genetic predispositions and environmental factors interact. These other approaches do not primarily address the impact of prenatal viral infections on development.
