Founder of Biological (or Neuroscience) Psychology School of Thought

Biological psychology, also known as biopsychology or neuroscience, is a field of psychology that focuses on the relationship between biological processes and behavior. The school of thought associated with biological psychology can be traced back to several influential figures in the history of psychology. One key figure in the development of this field is James W. Black, who is often considered one of the founders of biological psychology.

James W. Black (1893–1968) was an American psychologist who played a crucial role in establishing the biological basis of behavior. He emphasized the importance of understanding the physiological and neurological mechanisms that underlie psychological processes. Black’s work, along with contributions from other researchers, laid the foundation for the integration of biology and psychology.

It’s important to note that the development of biological psychology involved the contributions of multiple researchers over time, and it was not solely the work of a single individual. As the field progressed, other prominent figures, such as Karl Lashley, Donald Hebb, and Paul D. MacLean, further advanced our understanding of the biological aspects of behavior and cognition.


Contributors of Biological (or Neuroscience) Psychology School of Thought

The field of biological psychology, also known as neuroscience or biopsychology, has been shaped by the contributions of several influential researchers and thinkers. While it is challenging to highlight all contributors, here are some key figures who played significant roles in the development of the biological psychology school of thought:

James W. Black (1893–1968):

Often considered one of the founders of biological psychology, Black emphasized the importance of understanding the physiological and neurological basis of behavior.

Karl Lashley (1890–1958):

An American psychologist, Lashley conducted pioneering research on the brain and behavior. His work, including studies on the localization of function in the brain, contributed to the understanding of the neural basis of behavior.

Donald Hebb (1904–1985):

A Canadian psychologist, Hebb’s most influential work is the “Hebbian theory,” which describes the role of synaptic plasticity in learning and memory. This theory has had a profound impact on the understanding of how neural connections contribute to behavior.

Paul D. MacLean (1913–2007):

An American neuroscientist, MacLean introduced the concept of the “triune brain,” which suggests that the human brain consists of three major components: the reptilian complex, the limbic system, and the neocortex. This framework has influenced the study of brain evolution and function.

Roger W. Sperry (1913–1994):

An American neuropsychologist, Sperry conducted groundbreaking research on split-brain patients, revealing the specialization of the two brain hemispheres. His work contributed to our understanding of lateralization of brain function.

David Hubel (1926–2013) and Torsten Wiesel (1924–2019):

This Nobel Prize-winning duo conducted pioneering research on the structure and function of the visual system, uncovering principles of sensory processing in the brain.

Eric R. Kandel:

A Nobel Prize-winning neuroscientist, Kandel is known for his research on the molecular mechanisms of learning and memory. His work has helped bridge the gap between cellular and molecular processes and behavioral outcomes.

Rita Levi-Montalcini (1909–2012) and Stanley Cohen (1922–2020):

Awarded the Nobel Prize in Physiology or Medicine, Levi-Montalcini and Cohen discovered nerve growth factor (NGF), a crucial molecule for the development and maintenance of the nervous system.

These figures, among others, have made significant contributions to the biological psychology school of thought by advancing our understanding of the intricate relationship between the brain, biology, and behavior.

Focus of Biological (or Neuroscience) Psychology School of Thought

The Biological Psychology school of thought, also known as neuroscience or biopsychology, focuses on understanding the relationship between biological processes and behavior. This field explores how the structure and function of the nervous system, including the brain and other physiological factors, influence thoughts, emotions, and actions. Here are some key focuses of Biological Psychology:


Examining the structure of the nervous system, including the organization of the brain, spinal cord, and peripheral nerves. Researchers in this field seek to understand how different brain regions are involved in specific cognitive and behavioral functions.


Investigating the electrical and chemical processes that occur within the nervous system. This includes studying how neurons communicate with each other through neurotransmitters and how electrical impulses are transmitted along neural pathways.


Exploring the role of neurotransmitters and other chemicals in the brain in influencing behavior and mental processes. Imbalances in neurotransmitter levels are often associated with various psychological disorders.


Examining the interaction between the nervous system and the endocrine system, including the study of hormones and their impact on behavior and mental states.


Investigating the role of genetics in shaping the structure and function of the nervous system. This includes understanding how genetic factors contribute to individual differences in behavior and susceptibility to mental disorders.

Biological Basis of Behavior:

Exploring how neural processes give rise to specific behaviors and cognitive functions. This involves understanding the mechanisms underlying perception, learning, memory, emotion, motivation, and other psychological phenomena.

Brain Imaging Techniques:

Utilizing advanced imaging technologies such as fMRI (functional Magnetic Resonance Imaging), PET (Positron Emission Tomography), and EEG (Electroencephalography) to observe and analyze brain activity in real-time, helping researchers correlate brain function with behavior.


Studying the effects of drugs on the nervous system and behavior. Psychopharmacologists investigate how different substances, including medications and recreational drugs, impact neural function and psychological well-being.

Evolutionary Psychology:

Considering the evolutionary history of the nervous system and how it has shaped adaptive behaviors. This perspective explores how certain behaviors and cognitive processes may have evolved to enhance survival and reproduction.

Biological psychology seeks to bridge the gap between the biological and psychological aspects of human and animal behavior, providing insights into the physiological underpinnings of mental processes and disorders. Researchers in this field often collaborate with professionals in other disciplines, such as genetics, biochemistry, and medicine, to gain a comprehensive understanding of the complex interplay between biology and psychology.
