Infantilism (physiological disorder)

Infantilism (physiological disorder) is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Infantilism (physiological disorder) rather than just read about it. In short: In medicine, infantilism is an obsolete term for various, often unrelated disorders of human development, up to developmental disability, which consist of retention of the physical and/or psychological characteristics of early developmental stages (infant, toddler, child, adolescent) into a relatively advanced age. Various types of infantilism were recognized, lumped together in the above superficial description.

Key takeaways

Infantilism (physiological disorder) belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Infantilism (physiological disorder) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Infantilism (physiological disorder) from memory before moving on to harder problems.

Reference excerpt

In medicine, infantilism is an obsolete term for various, often unrelated disorders of human development, up to developmental disability, which consist of retention of the physical and/or psychological characteristics of early developmental stages (infant, toddler, child, adolescent) into a relatively advanced age. Various types of infantilism were recognized, lumped together in the above superficial description. With better understanding of the endocrine system and genetic disorders, various disorders which included the word "infantilism" received other names. For example, Brissaud's infantilism, described by Édouard Brissaud in 1907, is now known as myxedema (a form of hypothyroidism); "intestinal infantilism" of Christian Archibald Herter is called coeliac disease. The Turner syndrome was described as "a syndrome of infantilism" by Henry Turner himself. Terms such as "genital infantilism" (infantilism in development of genitals, hypogenitalism), or "sexual infantilism" (lack of sexual development after expected puberty or delayed puberty) may still be seen, and are considered to be synonyms of hypogonadism. "Somatic infantilism" refers to infantilism of overall bodily development. Speech infantilism is a speech disorder. Similarly to some other medical terms (cretinism, idiotism), "infantilism"/"infantile" may be used pejoratively (synonymous to "immature").

Worked examples

Example 1 — a first encounter with Infantilism (physiological disorder)

Start with the simplest possible case. Write down what Infantilism (physiological disorder) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Infantilism (physiological disorder) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Infantilism (physiological disorder) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Infantilism (physiological disorder)

In research: Infantilism (physiological disorder) appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Infantilism (physiological disorder) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Infantilism (physiological disorder) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Abnormal psychology stubs, Developmental disabilities, so understanding it makes those chapters shorter.
In everyday life: Look for Infantilism (physiological disorder) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
