Article Discussion
Ignoring Perfect Knowledge
Discussion Questions
- What is the main lesson from this article?

- What are examples of users relying on imperfect memory to save
time? For these examples, what are effective strategies for avoiding errors?
Menu analysis
For the following scenarios, answer the following questions:
- How much time (estimate the median for the population) will
be needed to select the link
- Will it be the right link for the user's navigation goal?
- First time user of the CTI web page
is interested in applying to a Masters program.

- The user visits Sun's Java page for the first time.
Wants to download the latest standard edition for Java.

Discussion Questions
- Examine Figure 4.2 in POMS chapter 4. Do users typically perform the Optimizing Rule or the Satisficing Rule?
- Do practiced users (i.e. users who are very familiar with the menu) use the strategies in Figures 4.1 and 4.2?
- Luce's choice axioms (see section 4.1.2) indicate that the presence of zero probability times do not affect which items are ultimately selected. But consider the following two menus:
Menu 1
- Item A (poor choice)
- Item B (poor choice)
- Item C (good choice)
- Item D (great choice)
Menu 2
- Item C (good choice)
- Item D (great choice)
- Item A (poor choice)
- Item B (poor choice)
Would users tend to make the same choices in both menus?
- Norman (in POMS) discusses restaurant menus and compares them to
computer memories. Whatever kinds of menus are there? Do people's
experiences with these metaphors affect how they use other kinds of
menus?
- When navigating the Google Directory (e.g. to search for DePaul), which problem-solving strategies are used:
- Generate and test
- Hill climbing
- Test-Operate-Test-Exit (TOTE)
- Means-Ends Analysis
