Ethics, Cognitive Load, and Trust

“Stories are just data with soul” 

— Brown 2010

I liked this quote from our last HCI class.

I also appreciate how Jamiahus and Kaitlyn talk about design in general terms, relating the fundamental principles to both physical and digital/virtual products. When talking about measures, one thing that surprised me was that UX metrics (such as error rate, time on task, efficiency, and abandonment) are considered fairly qualitative.

We’ve had two ethics classes with Eliot Winer. I found the second day to be more constructive because we were talking about scenarios that we might actually experience in our careers. The topic of contracts was particularly interesting. My classes thus far have recommended outlining contracts in great detail to avoid miscommunication, so I had just assumed that this was best practice. However, I can see the benefit of not promising too much in the contract, and just delivering what you can, taking into consideration the expectations that you believe your client to have.

In regards to the first day, I think this is a very compelling article: Marginalism and the Morality of Pricing Human Lives.

Jared Danielson spoke about his research in veterinary education.

The three types of cognitive load that he outlined apply to design in general:

  • Intrinsic load — Irreducible cognitive requirements of a task
    • Bad
    • Dependent on the person
    • Can’t do anything about it
  • Extraneous load — static/interfering information or processes
    • Bad
    • Should be minimized
  • Germane/Relative load — designed/intentional, for the purpose of learning
    • Good
    • Should be maximized

He recommended looking up Deliberate Practice, by Ericsson.

Today we covered effect size and signal detection theory. TIMELI chose a good article! The various influences on trust of an automated system will be on my mind, and might spark further reading for my own projects.

And lastly, because I don’t believe in blogging without photos… Here’s a picture from the etiquette lunch (with Austin mysteriously missing…)
