MOD128 – Phrenology

Definition

Phrenology is a historical pseudoscience that claimed to determine a person’s character, personality traits, and mental abilities based on the shape and contours of the skull. It posits that different regions of the brain are responsible for specific personality traits, and these can be assessed by examining the shape, size, and bumps (called phrenological faculties) on the skull. While no longer considered scientifically valid, phrenology played a significant role in the development of modern neuroscience and psychology.

Explanation

Phrenology emerged in the late 18th century and gained considerable popularity in the 19th century as a method of psychological analysis, particularly in Britain and the United States. The practice was developed by Franz Joseph Gall, a German physician, and further popularised by his assistant, Johann Gaspar Spurzheim.

Practitioners, known as phrenologists, believed that the brain’s surface could be divided into distinct areas, each corresponding to different faculties such as benevolence, intellect, destructiveness, and spirituality. By feeling the bumps and contours of the skull, phrenologists purported to assess an individual’s strengths, weaknesses, and personality traits. This process, often referred to as a “head reading”, was conducted using a phrenological head – a model of the human skull marked with the various faculties.

Phrenology had a profound impact on 19th-century society, influencing fields such as education, criminology, and even employment practices. Many prominent figures of the time, including Queen Victoria and Prince Albert, showed interest in the practice.

Although modern scientific understanding has discredited phrenology as inaccurate and lacking empirical evidence, its historical significance cannot be overlooked. The concept that specific brain regions are responsible for distinct functions, while not in the simplistic manner proposed by phrenology, laid the groundwork for future neurological studies. Today, phrenology is primarily studied as a historical curiosity and a cautionary tale about the importance of scientific rigour in developing theories about human behaviour and cognition.

Evidence to Efficacy/ Neuroscience

While phrenology is no longer considered a valid scientific practice, it has played a significant role in the historical development of neuroscience and psychology. Its influence can be seen in the way it encouraged early researchers to consider the localisation of brain functions, a concept that has proven valuable in modern neuroscience.

The Edinburgh Phrenological Society, established in 1820, was a hub for intellectual discourse and scientific inquiry in the 19th century. This society contributed to the broader understanding of human behaviour and cognition, even if the specific claims of phrenology were later disproven.

Recent research has explored phrenology from a historical and sociological perspective. A study published in the journal Medical History examined how 19th-century Americans engaged with phrenology as a form of ‘knowledge experiment’. This research highlights how phrenology encouraged self-reflection and personal growth, aspects that remain relevant in contemporary approaches to self-improvement and mental health.

While modern neuroscience has moved beyond the specific claims of phrenology, the field’s emphasis on the relationship between brain structure and function continues to be a fundamental principle in current research. Advanced neuroimaging techniques, such as MRI, now allow us to explore brain-behaviour relationships in ways that early phrenologists could only imagine.

The legacy of phrenology can also be seen in the development of more rigorous scientific methods. The criticism and eventual rejection of phrenology contributed to the establishment of stricter standards for scientific evidence and methodology, which has benefited all areas of scientific inquiry.

In essence, while phrenology itself is not considered a valid practice, its historical impact on the development of neuroscience, psychology, and scientific methodology should not be overlooked. It serves as a reminder of the importance of empirical evidence and rigorous scientific inquiry in our ongoing quest to understand the human mind and behaviour.

Self Study Resources

If you’d like to deepen your understanding of phrenology and its historical significance, consider engaging in the following self-study activities:

Read Historical Texts: Explore classic works by Franz Joseph Gall and Johann Gaspar Spurzheim to grasp the foundational ideas of phrenology. These texts provide insight into the early theories of brain function and personality assessment.

• On the Functions of the Brain and of Each of Its Parts by Franz Joseph Gall (1835) – This is an English translation of Gall’s major work, which outlines his theories on phrenology.
• Anatomie et physiologie du système nerveux en général, et du cerveau en particulier by Franz Joseph Gall and Johann Gaspar Spurzheim (1810-1819) – This four-volume work (in French) is considered Gall’s magnum opus on phrenology and brain anatomy.
• The Physiognomical System of Drs. Gall and Spurzheim by Johann Gaspar Spurzheim (1815) – This book presents Spurzheim’s interpretation and expansion of Gall’s ideas.
• The Principles of Psychology by William James (1890) – This foundational text laid the groundwork for modern psychology and neuroscience.
• The Organization of Behaviour by Donald Hebb (1949) – Hebb’s work introduced the concept of neuroplasticity and is considered a classic in neuroscience.

Exploring Modern Neuroscience: Investigate how concepts of brain localisation have evolved since the days of phrenology. Accessible books or online courses on neuroscience can offer a contemporary perspective on how brain structure relates to behaviour and personality.

• The Brain: The Story of You by David Eagleman (2015) – This book offers an accessible introduction to modern neuroscience for general readers.
• Principles of Neural Science by Eric Kandel et al. (6th edition, 2021) – This comprehensive textbook is widely used in neuroscience education and provides an up-to-date overview of the field.
• The Neuroscientist Who Lost Her Mind by Barbara K. Lipska (2018) – This memoir offers a unique perspective on brain function from a neuroscientist who experienced mental illness.
• Connectome: How the Brain’s Wiring Makes Us Who We Are by Sebastian Seung (2012) – This book explores the cutting-edge field of connectomics and its implications for understanding brain function.
• The Disordered Mind: What Unusual Brains Tell Us About Ourselves by Eric R. Kandel (2018) – Kandel examines various brain disorders to shed light on normal brain function and human behaviour.

Related Therapies

While phrenology itself is not practised today, several related fields have emerged that share interests in personality assessment and human behaviour. These include:

Psychometrics: This field focuses on measuring psychological variables, including personality traits, through standardised tests, offering a robust framework for understanding individual differences.

Personality Psychology: Modern theories of personality, such as the Big Five personality traits or the Myers-Briggs Type Indicator (MBTI), explore the complexities of human behaviour and character in ways that build on or diverge from earlier ideas.

Craniosacral Therapy (MOD090): A gentle, hands-on approach that focuses on the craniosacral system, though it operates under different principles than phrenology, it reflects an ongoing interest in the connections between physical form and psychological state.

Graphology (MOD129): The analysis of handwriting to infer personality traits shares a similar ethos with phrenology, linking physical characteristics to psychological attributes, though it too lacks scientific validation.
