Karen Hollis

Karen Hollis 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 Karen Hollis rather than just read about it. In short: Karen Hollis is an American professor of psychology and education at Mount Holyoke College in South Hadley Massachusetts. Hollis's research focusses on an evolutionary approach to learning and cognition in non human animals.

Key takeaways

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

Reference excerpt

Karen Hollis is an American professor of psychology and education at Mount Holyoke College in South Hadley Massachusetts. Hollis's research focusses on an evolutionary approach to learning and cognition in non human animals. She served as the head of the American Psychological Association's sixth division (behavioural neuroscience and comparative psychology) from 2006 to 2007 and the third division (experimental psychology] from 2010 to 2011. Hollis was the first woman to head the third division. She has served on the editorial boards of many journals, including Animal Behaviour, Animal Learning & Behavior and the Journal of Comparative Psychology. Hollis received a B.A. from Slippery Rock State College (now Slippery Rock University of Pennsylvania) and a Ph.D. from the University of Minnesota. In 2016 Hollis was honored Comparative Cognition Society for her contributions to the study of animal cognition.

Worked examples

Example 1 — a first encounter with Karen Hollis

Start with the simplest possible case. Write down what Karen Hollis 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 Karen Hollis 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 Karen Hollis 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 Karen Hollis

In research: Karen Hollis 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 Karen Hollis 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: Karen Hollis is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century American psychologists, 21st-century American women, American women academics, so understanding it makes those chapters shorter.
In everyday life: Look for Karen Hollis 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.
