Per Saugstad is a astronomy 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 Per Saugstad rather than just read about it. In short: Per Saugstad (24 October 1920 – 7 November 2010) was a Norwegian psychologist. He was Professor of Psychology at the University of Oslo, and is noted for his work on visual perception, thinking, language, and the history of psychology.

Key takeaways

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

Reference excerpt

Per Saugstad (24 October 1920 – 7 November 2010) was a Norwegian psychologist. He was Professor of Psychology at the University of Oslo, and is noted for his work on visual perception, thinking, language, and the history of psychology.

Career He was born in Oslo. After getting a cand.philol. degree from the University of Oslo in 1945, he went to the United States, receiving a Ph.D. in Psychology from the University of Chicago in 1952. Back in Norway, he joined the Department of Psychology at the University of Oslo, rising to docent in 1962 and full professor in 1967. He retired in 1990. In Chicago Saugstad had become interested in experimental psychology, and his American approach to psychology was initially met with some resistance in Oslo, where the psychology department was still dominated by psychoanalysis in the 1950s. Saugstad has done important research in several areas, such as visual perception, thinking, and language. Among his books are An inquiry into the foundations of psychology (1965), A Theory of Communication and Use of Language. Foundations for the Study of Psychology (1977), A Theory of Language and Understanding (1980), Language: A theory of its structure and use (1989). In later years, his work focused on the history of psychology, culminating in the book A History of Modern Psychology. He was a member of the Finnish Academy of Science and Letters. He died in November 2010. He was the father of professor of pediatrics Ola Didrik Saugstad and professor of philosophy Jens Saugstad.

Worked examples

Example 1 — a first encounter with Per Saugstad

Start with the simplest possible case. Write down what Per Saugstad claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Per Saugstad 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 Per Saugstad 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 Per Saugstad

In research: Per Saugstad appears in astronomy 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 Per Saugstad 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: Per Saugstad is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1920 births, 2010 deaths, Academic staff of the University of Oslo, so understanding it makes those chapters shorter.
In everyday life: Look for Per Saugstad 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.
