Somatotype and constitutional psychology

Last updated

Somatotype is a theory proposed in the 1940s by the American psychologist William Herbert Sheldon to categorize the human physique according to the relative contribution of three fundamental elements which he termed somatotypes, classified by him as ectomorphic, mesomorphic, and endomorphic. He created these terms borrowing from the three germ layers of embryonic development: The endoderm, (which develops into the digestive tract), the mesoderm, (which becomes muscle, heart, and blood vessels) and the ectoderm (which forms the skin and nervous system). [1] Later variations of these categories, developed by his original research assistant Barbara Heath, and later by Lindsay Carter and Rob Rempel, are used by academics today. [2] [3]

Contents

Constitutional psychology is a theory developed by Sheldon in the 1940s, which attempted to associate his somatotype classifications with human temperament types. [4] [5] The foundation of these ideas originated with Francis Galton and eugenics. [2] Sheldon and Earnest Hooton were seen as leaders of a school of thought, popular in anthropology at the time, which held that the size and shape of a person's body indicated intelligence, moral worth and future achievement. [2]

In his 1954 book, Atlas of Men, Sheldon categorized all possible body types according to a scale ranging from 1 to 7 for each of the three somatotypes, where the pure endomorph is 7–1–1, the pure mesomorph 1–7–1 and the pure ectomorph scores 1–1–7. [6] [7] [8] From type number, an individual's mental characteristics could supposedly be predicted. [7] In a late version of a pseudoscientific thread within criminology in which criminality is claimed to be an innate characteristic that can be recognized through particular physiognomic markers (as in Cesare Lombroso's theory of phrenology), Sheldon contended that criminals tended to be 'mesomorphic'. [9] The system of somatotyping is still in use in the field of physical education. [10]

The three types

Comparison of Sheldon's body types

Sheldon's "somatotypes" and their associated physical and psychological traits were characterized as follows: [3] [8] [11]

SomatotypePhysical traitsPsychological traitsNotes
Ectomorphiccharacterized as skinny, weak, and usually tall with low testosterone levelsdescribed as intelligent, gentle and calm, but self-conscious, introverted and anxious. [3] [6] [8] [12]
Mesomorphiccharacterized as naturally hard and strong, with even weight distribution, muscular, thick-skinned, and as having good posture with narrow waistdescribed as competitive, extroverted, and tough. [3] [6] [8]
Endomorphic  characterized as fat, usually short, and having difficulty losing weightdescribed as outgoing, friendly, happy and laid-back, but also lazy and selfish [3] [6] [8]

Stereotyping

There may be some evidence that different physiques carry cultural stereotypes, as some cultures are more prone to certain physiques. According to one study endomorphs are likely to be perceived as slow, sloppy, and lazy. Mesomorphs, in contrast, are typically stereotyped as popular and hardworking, whereas ectomorphs are often viewed as intelligent yet fearful. [13]

Heath–Carter formula

Sheldon's physical taxonomy is still in use, particularly the Heath–Carter variant of the methodology. [14] This formulaic approach utilises an individual's weight (kg), height (cm), upper arm circumference (cm), maximal calf circumference (cm), femur breadth (cm), humerus breadth (cm), triceps skinfold (mm), subscapular skinfold (mm), supraspinal skinfold (mm), and medial calf skinfold (mm), and remains popular in anthropomorphic research, according to Rempel: "with modifications by Parnell in the late 1950s, and by Heath and Carter in the mid 1960s somatotype has continued to be the best single qualifier of total body shape". [15]

This variant utilizes the following series of equations to assess a subject's traits against each of the three somatotypes, each assessed on a seven-point scale, with 0 indicating no correlation and 7 indicating a very strong correlation:

where:

This numerical approach has gone on to be incorporated in the current sports science and physical education curriculums of numerous institutions, ranging from the UK's secondary level GCSE curriculums (14- to 16-year-olds), the Indian UPSC Civil Service exams, to MSc programs worldwide, and has been utilized in numerous academic papers, including:

Criticism

"The Varieties of Human Physique" by Sheldon et al (1940) classified body types into 3 categories using data processes that would not be accepted by researchers today. [30] Sheldon's ideas that body type was an indicator of temperament, moral character or potential – while popular in an atmosphere accepting of the theories of eugenics – were later disputed. [2] [31]

A key criticism of Sheldon's constitutional theory is that it was not a theory at all but a general assumption of continuity between structure and behavior and a set of descriptive concepts to measure physique and behavior in a scaled manner. [3] His use of thousands of photographs of naked Ivy League undergraduates, obtained without explicit consent from a pre-existing program evaluating student posture, has been strongly criticized. [2] [32]

While popular in the 1950s, [32] Sheldon's claims have since been dismissed as "quackery". [3] [4] [33] [34] [35] Barbara Honeyman Heath, who was Sheldon's main assistant in compiling Atlas of Men, accused him of falsifying the data he used in writing the book. [2]

Body mass index (BMI) is a value derived from the mass (weight) and height of a person. The BMI is defined as the body mass divided by the square of the body height, and is expressed in units of kg/m2, resulting from mass in kilograms (kg) and height in metres (m).

In graph theory, the girth of an undirected graph is the length of a shortest cycle contained in the graph. If the graph does not contain any cycles, its girth is defined to be infinity. For example, a 4-cycle (square) has girth 4. A grid has girth 4 as well, and a triangular mesh has girth 3. A graph with girth four or more is triangle-free.

Anthropometry refers to the measurement of the human individual. An early tool of physical anthropology, it has been used for identification, for the purposes of understanding human physical variation, in paleoanthropology and in various attempts to correlate physical with racial and psychological traits. Anthropometry involves the systematic measurement of the physical properties of the human body, primarily dimensional descriptors of body size and shape. Since commonly used methods and approaches in analysing living standards were not helpful enough, the anthropometric history became very useful for historians in answering questions that interested them.

The body fat percentage (BFP) of a human or other living being is the total mass of fat divided by total body mass, multiplied by 100; body fat includes essential body fat and storage body fat. Essential body fat is necessary to maintain life and reproductive functions. The percentage of essential body fat for women is greater than that for men, due to the demands of childbearing and other hormonal functions. Storage body fat consists of fat accumulation in adipose tissue, part of which protects internal organs in the chest and abdomen. A number of methods are available for determining body fat percentage, such as measurement with calipers or through the use of bioelectrical impedance analysis.

The Positivist School was founded by Cesare Lombroso and led by two others: Enrico Ferri and Raffaele Garofalo. In criminology, it has attempted to find scientific objectivity for the measurement and quantification of criminal behavior. Its method was developed by observing the characteristics of criminals to observe what may be the root cause of their behavior or actions. Since the Positivist's school of ideas came around, research revolving around its ideas has sought to identify some of the key differences between those who were deemed "criminals" and those who were not, often without considering flaws in the label of what a “criminal” is.

Characteristic modes (CM) form a set of functions which, under specific boundary conditions, diagonalizes operator relating field and induced sources. Under certain conditions, the set of the CM is unique and complete (at least theoretically) and thereby capable of describing the behavior of a studied object in full.

<span class="mw-page-title-main">Body shape</span> General shape of a human body

Human body shape is a complex phenomenon with sophisticated detail and function. The general shape or figure of a person is defined mainly by the molding of skeletal structures, as well as the distribution of muscles and fat. Skeletal structure grows and changes only up to the point at which a human reaches adulthood and remains essentially the same for the rest of their life. Growth is usually completed between the ages of 13 and 18, at which time the epiphyseal plates of long bones close, allowing no further growth.

The Corpulence Index (CI) is a measure of corpulence, or of leanness in other variants, of a person calculated as a relationship between mass and height. It was first proposed in 1921 as the "Corpulence measure" by Swiss physician Fritz Rohrer and hence is also known as Rohrer's Index. It is similar to the body mass index, but the mass is normalized with the third power of body height rather than the second power. In 2015, Sultan Babar showed that CI does not need to be adjusted for height after adolescence.

Obesity classification is a ranking of obesity, the medical condition in which excess body fat has accumulated to the extent that it has an adverse effect on health. The World Health Organization (WHO) classifies obesity by body mass index (BMI). BMI is further evaluated in terms of fat distribution via the waist–hip ratio and total cardiovascular risk factors. In children, a healthy weight varies with age and sex, and obesity determination is in relation to a historical normal group.

<span class="mw-page-title-main">Posture (psychology)</span> Aspect of nonverbal communication

In humans, posture can provide a significant amount of important information through nonverbal communication. Psychological studies have also demonstrated the effects of body posture on emotions. This research can be traced back to Charles Darwin's studies of emotion and movement in humans and animals. Currently, many studies have shown that certain patterns of body movements are indicative of specific emotions. Researchers studied sign language and found that even non-sign language users can determine emotions from only hand movements. Another example is the fact that anger is characterized by forward whole body movement. The theories that guide research in this field are the self-validation or perception theory and the embodied emotion theory.

The history of anthropometry includes its use as an early tool of anthropology, use for identification, use for the purposes of understanding human physical variation in paleoanthropology and in various attempts to correlate physical with racial and psychological traits. At various points in history, certain anthropometrics have been cited by advocates of discrimination and eugenics often as part of novel social movements or based upon pseudoscience.
