Key takeaways

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

Reference excerpt

Rolf Reber (born 17 May 1959) is a professor of psychology at the University of Oslo.

Research Rolf Reber is known for his research on processing fluency, especially the processing fluency theory of aesthetic pleasure he developed together with Norbert Schwarz from the University of Michigan and Piotr Winkielman from the University of California at San Diego. The core assumption of the theory is that an audience draws aesthetic pleasure from the fact that an object can be processed easily, especially if a viewer remains unaware of the source of this processing ease.

Theory resolution This theory resolves an apparent contradiction between the uniformity of musical preferences in infants and the cultural differences in musical tastes in adults. Infants prefer consonant melodies because newborns share biological mechanisms that make them process consonance in music more easily than dissonance. When children grow up, they are exposed to the music of their culture, explaining why individuals from different cultures have different musical tastes. In addition, the research found that processing fluency influences both affect and the judged truth of statements, suggesting that ease of processing is a common underlying experience in both perceived beauty and judged truth.

Observation This observation fits anecdotal observations that mathematicians and scientists sometimes use the beauty of a theorem as an indication of its truth. This idea has been explored in more recent work. Processing fluency and its effects can help explain the "Aha"-experience. The processing fluency theory of aesthetic pleasure has influenced work in psychology, philosophy, marketing, and finance. An extension of the processing fluency theory takes account of the fact that many artworks are difficult to process. Nevertheless, audiences interpret these artworks in a meaningful way and like them.

Instructional technique More recently, Rolf Reber and his collaborators have developed and explored Example Choice, an instructional technique designed to increase relevance and student interest in learning abstract principles in mathematics and science. Students are given examples from different topics that all address the same underlying principle, and a student has to choose the example that interests him or her most. The chosen example is then used to explain the formal principle. This technique is supposed to connect the formal principle to students' interest. Research has shown that students become more interested and spend more time learning the principle when they can choose an example than when they are given an example.

Author Rolf Reber is the author of the book Critical Feeling that introduces the concept of critical feeling which extends the notion of critical thinking and two popular science books in German, among them Kleine Psychologie des Alltäglichen (A brief psychology of everyday life) which has been translated into Norwegian, Korean and Chinese.

Worked examples

Example 1 — a first encounter with Rolf Reber

Start with the simplest possible case. Write down what Rolf Reber 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 Rolf Reber 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 Rolf Reber 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 Rolf Reber

In research: Rolf Reber 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 Rolf Reber 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: Rolf Reber is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1959 births, Academic staff of the University of Bergen, Academic staff of the University of Oslo, so understanding it makes those chapters shorter.
In everyday life: Look for Rolf Reber 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.
