Answer :
Final answer:
All the mentioned types - endomorphs, mesomorphs, and ectomorphs - are part of Sheldon's somatotypes. Although Sheldon's methods have been criticized and largely discredited, his classifications remain a notable part of criminological history.
Explanation:
The somatotypes school of criminology, pioneered by William Herbert Sheldon, categorizes human physiques into three primary types: endomorphs, mesomorphs, and ectomorphs. Endomorphs are characterized by a rounder physique with more body fat, mesomorphs possess a muscular build with a large bone structure, and ectomorphs are identified by a thinner frame and smaller bone structure. When asked which of these is not one of Sheldon's somatotypes, the correct answer would be none, as all are part of Sheldon's classification. Sheldon's research linked these types with certain personality traits and behaviors, though this approach has been discredited in contemporary psychology for lack of scientific validation.
Sheldon's findings primarily indicated that juvenile delinquents were often mesomorphs, which could be hypothesized as linked to high testosterone levels and aggressive behavior, although alternative explanations could include socio-environmental factors.
