1What is Recall?
Out of the true labels, how many are you able to retrieve correctly.
2What is Precision?
Out of all positive labels, which ones are true positive.
3What is one practical application of cognitive models?
Provide (and help to understand) human-like experiences (e.g., game opponent).
4What is a second practical application of cognitive models?
Make appropriate, (adaptive) decisions, based on understanding of user's behavior.
5What are examples of adaptive decisions cognitive models can inform?
Feedback (tutor), Difficulty (game), Adaptive interface (interruptions).
6What other practical applications do cognitive models have?
Software & interface (re-) design, Usability.
7What is one benefit of dividing systems into Marr's levels or Newell's bands?
Avoids mixing levels (goal, method, hardware).
8How do Marr/Newell levels help communication?
Prevents talking past each other (e.g., neural vs. algorithmic accounts are just different levels).
9How do Marr/Newell levels guide explanation?
They help show the appropriate level of detail (e.g., you don’t need ion channels to explain chess).
10How do Marr/Newell levels support design?
They clarify that the same algorithm (algorithmic level) can run on different hardware (implementation level).
11What does Significance (p-value) tell you?
Whether an effect is likely real (is there a difference vs. no difference).
12What does Effect size (e.g., Cohen’s d) tell you?
How big the effect is (the actual magnitude of the difference).
