Biological psychology, also known as biopsychology or psychobiology, is founded on several core assumptions. Firstly, it posits that biological processes fundamentally influence behavior and mental processes. This approach assumes that the brain, nervous system, genetics, and neurochemical activity are key determinants of behavior (Gazzaniga et al., 2018). It also presumes that understanding biological mechanisms can lead to better insights into psychological disorders and human functioning, emphasizing a scientific, reductionist perspective that seeks to explain behavior through observable biological factors.

The development of biological psychology is the result of the convergence of multiple disciplines. Neuroscience provides insights into neural structures and functions, while psychology offers theories of behavior and cognition. Physiology contributes understanding of the body's biological systems, and genetics explores hereditary influences on behavior (Pinel, 2018). Additionally, pharmacology enhances understanding of neurochemical influences, making the field a multidisciplinary amalgamation aimed at explaining the biological basis of behavior comprehensively.

Historically, early examples of a biological approach include Galen's anatomical studies of the brain and the use of phrenology in the 19th century, which attempted to link skull shape to personality traits (O’Connell, 2017). In the 20th century, the advent of neuroimaging techniques such as EEG, PET, and MRI securely established a biological framework for understanding behavior. The work of researchers like Sperry and Gazzaniga, who studied split-brain patients, further exemplifies the biological approach by linking specific brain regions to functions and behaviors, advancing the scientific understanding of brain-behavior relationships.

Modern careers stemming from biological psychology are diverse, reflecting its interdisciplinary nature. Neuroscientists conduct research on brain structure and function, often working in academia or medical settings to understand neurological and psychiatric disorders (Kandel et al., 2013). Clinical neuropsychologists evaluate and treat brain injury patients, employing biological assessments to inform therapy. Pharmacologists develop psychoactive medications targeting neural systems, contributing to psychiatric treatment. Additionally, research positions in biotech companies, academic institutions, and healthcare organizations are common, focusing on understanding biological bases of behavior, cognitive functions, and mental health conditions.

Today, biological psychology is highly regarded within the broader psychological community. It is viewed as a vital, empirical approach that complements cognitive, behavioral, and social perspectives (Cacioppo & Berkman, 2014). While some critics argue it reduces human experience solely to biology, most professionals acknowledge its importance for understanding complex mental processes and disorders. Its integration with neuroimaging, genetics, and molecular biology has fostered a more comprehensive understanding of human behavior, positioning biological psychology as a cornerstone of contemporary neuroscience and clinical psychology.
