This site is about: (1) my professional self, (2) my research into cognition and (3) musings about the intersection of cognition and design.

Basic cognitive research is a necessary component of successful user-centered design. Only through scientific thinking can we make technology intuitive and productive. My goal is to integrate basic research with useful applications.
Amazon.com Item Page Clutter
Amazon.com is an unholy mess when shopping for anything, including books! Let’s say you’re looking for the first Harry Potter book. The URL is http://www.amazon.com/Harry-Potter-Sorcerers-Stone-Book/dp/0590353403/ref=pd_bxgy_b_text_b/002-6815992-5484811?ie=UTF8&qid=1184898138&sr=1-3, which is already bad. But if you want a hard copy, it will take ten pages of paper to print out! TEN PAGES of content for Harry Potter. What’s in those ten pages, you ask? Well, the categories are:
That’s twenty categories. Twenty! Working memory, depending on who you ask, can hold four (Cowan, 2001) to seven (Miller, 1956) items, and attention can only process so much of the visual field at a time (Rensink, O’Regan & Clark, 1997). Yet Amazon decides to give a topic like “Are you the publisher or author?” valuable space just in case J. K. Rowling stops by.
What to do? Well, that’s easy.
- Table of contents at the top of the page to easily jump to specific sections
- Cut down on the categories - which ones do users really need?
- Allow user-selectable categories. Amazon already tracks so much about shopping habits, they should track site preferences.
A simple survey would likely suffice, but so would a task analysis or even an eyetracking study. I’d bet that the eyes would move all around the page but never fixate for very long, meaning that the user was having trouble focusing on one particular piece of information - there’s just too much. Amazon is great for finding an amazing array of books and everything else. Now they should focus on not presenting an overwhelming array of information about products to the user.
