Attention Controls Errors

Fantastical Halloween

Books are good for the Soul

We are quickly falling into Fall. Warm sweaters, blankets, and books. But why bother with books when there is so much other entertainment around? Netflicks, HBOs, Amazons of the world are eager to grab hold of our eyeballs and never let go. It’s great for their bottom line. In 2017, the American Time Use Survey (Bureau of Labor Statistics) said that according to their survey, the number of Americans who read for pleasure had dropped by 30% since 2003. Who has the time, right? I hear that a lot too. “I’d read, but I have kids…I commute…I work long hours…I read at work…” There are many excuses. The one that most people don’t typically mention is that it is much easier to plump on a couch and watch something on TV or to simply play on one’s cell phone (for those who no longer own a TV). But reading is an active activity, while watching videos is passive. Cognitively, that makes a huge difference. Consider a piano. About 100 years ago, most households in America (middle class) had a piano in their parlor. Everyone learned to play a little bit. People could read music and play it off a sheet.…

Inattention Errors in Extemporaneous Writing

Rapefruit

Automation provides many opportunities for inattention errors. Extemporaneous writing/typing is particularly prone to errors so egregious that they are funny… in retrospect. Here are a few examples of “scary” autocorrect mistakes as well as other problems caused by limited or spit [sorry, that was “split”] attention on the task of communication. 1. Everyone fails sometimes It is easy to fail when we are in a hurry, or are under pressure, or don’t proofread our work before it goes out. Some fails are the result of trying to be too clever and not getting a second opinion. Some fails are due to lack of process — a second pair of eyes on the copy would have noticed the “extra word” problem. Some fails are easily caught via a spellchecker… But in some cases, a spellchecker does help… And in many cases, spellcheck is the CAUSE of strange communications. I had a few of those myself… 2. Errors are different from mistakes Mistakes are things that we know are wrong the moment we notice them — the head-slappers! They are usually caused by inattention on the task. Errors are different. Errors result from true ignorance. But it doesn’t make the resulting fails…

Review eBook: Affordances and Design

Manches a Gigots

Victor Kaptelinin, a Professor at the Department of Information Science and Media Studies, University of Bergen, Norway, and the Department of Informatics, Umeaa University, Sweden, just published an eBook with Interaction Design Foundation: “Affordances and Design.” I was asked to write a review of this book and provide some insights into using affordances in interaction design and HCI. Let me start by providing the definition of affordance as given by Donald Norman: In his eBook, Victor Kaptelinin provides the history of the idea of affordance from its initial introduction by James Gibson in 1977 to the present day. The eBook’s bibliography and reference section is a great place to start the exploration of this topic for anyone new to these ideas. Unfortunately, the book doesn’t help much if an individual is looking for some guidance on how to apply these ideas in practical situations during interaction design or HCI design. For clarity’s sake, allow me to give a very brief explanation of affordances, from their roots to the present time. When James Gibson first introduced the concept of affordances, he focused on physical environment — what actions are possible? And the set of these action were invariable — just because…

Perceptual Focus Error

Early on in my academic career, I did research in a middle school classroom. Computers were just introduced to a bunch of kids that never experienced them directly before. There were very few computers in schools at the time, and students were bunched up in groups around each one. One kid got to sit and control the keyboard, another student controlled the mouse. (I bet you know the genders of these two kids.) Most kids just focused their attention on the screen. The task was to familiarize with how the desktop computer interface worked. At the end of the activity, I got to interview the kids. One of the surprises was how many of the kids didn’t associate the movement of the mouse with the action on the screen. To connect the two actions together, a kid would have had to know that mouse movements and a pointer were related. It was not an obvious observation, especially in a tight crowd of a student group around the computer screen. And to this day, this required double focus is difficult for kids on the Autistic spectrum (iPads are much more intuitive for this population). One of the conclusions of my study…

Where to post the “OK” Button on the Screen?

OK Button on Early Mac

I have very strong opinions about where on the screen the OK or NEXT or SUBMIT buttons go in relation to CANCEL. Without giving it away, I’m going to walk through the design decision tree and provide a lot of references for both sides of the issue — yes, there are strong feelings about the right versus the left position choice. I’m not alone! Passive versus Active Buttons Active Buttons are the ones that advance the action to the next level. Passive ones return the users to previous state, negate the action sequence. OKAY, OK, NEXT, SUBMIT, ACCEPT, GO are all active buttons. CANCEL, BACK, PREVIOUS are action that reverse forward momentum and push the user to places they’ve been before. HELP and INFO sidetrack the user and distract from forward thrust of activity. In general, product designers want to move the users toward their goals — thus we want the perceptual focus to be on the action buttons. We want to make sure that users fist see the way forward, and then click on the right button that propels them forward to completion of the task. All distractions and side movements should be downplayed with Interface Design with the…

Emotional Scaffolding

Processing emotions takes time and energy. Part of the working memory is taken up by analyzing the emotional state of others, environmental stresses, personal feelings, and anxiety. Since working memory is an extremely limited resource, anything that takes up space there without our bidding (against our will) takes away from our ability to think through situations, to problem solve, and to make well-reasoned decisions. Instead of thinking, we are using up the working memory for processing emotions. Sometimes, emotions are just the right thing to focus on — to pay attention to. How does this painting makes me feel? Do I like this person? This music feels good… But if you are taking a math test, focusing on how much you really hate test-taking takes away from your ability to take the test. It is very common for individuals to “get” the subject matter, but fail the test. Some people are good at dealing with anxieties and some have trouble controlling their attention controls away from fretting. That’s one of the reason some educators are talking about doing away with summative assessments (final exams) in favor of continuous assessment (assessment as part of learning) — the on-going observation of students’…
