Cognitive Blindness: Super-recognizers

by  • 

Health Check, the BBC World Service’s weekly round up of global health stories, did an audio broadcast on super-recognizers—people with extraordinary abilities to recognize faces. You can listen to the entire story by Claudia Hammond at http://news.bbc.co.uk/2/hi/health/8665805.stm This story deals with differences in ability to recognize faces. There are people who are so bad at it that it is a pathology—when a mother can’t recognize her child among the pupils in the day care center, it’s more than inconvenient. Then there are all those embarrassing moments when you meet someone at a party for what you think is the first time only to have that person insist that you’ve met before. And the far end of the continuum, there are the super-recognizers—individuals that never forget a face even after a very brief interaction. We only now recognize the fact of super-recognizer, because most of us are not too bad and not too good at facial recognition—we are mostly average. And our average ability to recognize faces limits our ability to spot people who could do better. We were experiencing cognitive blindness—inability to perceive cognitive differences in abilities of others. And super-recognizers, similarly, didn’t know that they were somehow different from…

Error Opportunity Space

by  • 

Confronted with one “True or False” question, an individual has a very small error opportunity space: three. There are three possible responses: true, false, or no answer. “No answer” will always be wrong, a betting man should choose one of the possible answers. But unfortunately situations where the error opportunity space is so narrow are rare. And in the real world, dealing with real problems, these spaces tend to be very large. Note that the size of the error opportunity space, EOS, makes no representations about the consequences of getting the problem right or wrong (or partially right or wrong). When the stock market tanked on May 7th, people involved in that process had a very large EOS. A week out, experts and participants are trying to figure out what went wrong and how to limit similar incidents in the future—they are trying, in effect, to drastically reduce the error opportunity space. This is a job of product designers. By analyzing the goals of the users and the system’s constraining variables, we can come up with conceptual design, interaction design, and interface design that would address the problems that were exposed on May 7th. Coming up with a solution is…

The Anatomy of Failure

by  • 

On May 7th 2010, at around 2:30 p.m. Eastern Time, the stock market went on a wild ride, dropping over 900 points in matter of just minutes. What happened? There’s lot’s of speculation, and some know more then they are willing to say. But what’s clear is that there was just the right confluence of world events, human and computer errors, and system-wide communication breakdown that triggered a mass sell-off of stocks at fantastic prices. In other words, there was a catastrophic failure during product interaction. I’m not an investment analyst and have limited knowledge in this subject area, but I am interested in product failure. So Thursday’s stock market episode was very interesting. Here’s a little background on the events of that day broken down into steps leading to the failure. Step 1: When the New York stock market opened on Thursday, bad news was streaming in from Europe—there were fears that Greece would ultimately default on its loans; its people were staging massive demonstrations in Athens; Euro was going down. Step 2: In our very interconnected world, this kind of news makes investors skittish and the stock market was dropping value all morning. Step 3: At around 2:45…

Globalization and Cultural Errors

by  • 

Jew's Ear Juice

There was a time when a product designed for a specific geopolitical region would have stayed there for the duration of its existence. With few exceptions, products didn’t travel the world to areas where they would be considered a fopaux. These products were cultural curiosities displayed by adventurous tourists for the pleasure and laughs of their friends and family. But things change. Product design and usability protocols now have to include culture experts. What works well in one place, for one group of users, at a particular time won’t do so under other circumstances.

Neuro-Parasites & Problem Solving Errors

by  • 

Dr. Robert Sapolsky is a professor of neurobiology at Stanford University. He started his career studying baboons, charting the relationship between stress hormones and an individual animal’s social ranking in the baboon society hierarchy. The lower the rank, the more stress the animal experiences, the more consequences there are to the health outcomes and longevity of the baboon. Making a parallel to human society, the conclusions of Dr. Sapolsky’s study is that it sucks to be at the bottom of the social order. In his books “Primate’s Memoir” and “Zebras Don’t Get Ulcers,” Dr. Sapolsky provides copious details of his work and his conclusions. (see Recommended Books for details) But residing on the bottom of the social ladder is not the only problem a mammal like us can experience. In his video interview with Edge (www.Edge.org), Dr. Sapolsky describes the adventures of Toxoplasma–a protozoan parasite carried by cats which causes an infection Toxo–in our amygdala. Post an active infectious state, Toxo is able to manipulate human dopamine levels. People with the post-Toxo infection have higher than normal dopamine levels, resulting in some interesting cognitive consequences. There’s been solid research that documents a high level of Toxo infections in schizophrenic patients. There…

Understanding Complex Visual Information…

by  • 

US Military PowerPoint slide designed to explain Afghanistan strategy.

…or not comprehending it, as the case may be. A few years ago, I wrote a paper about people’s ability to comprehend complex visual information such as graphs, charts, diagrams, maps, and so on. Intuitively, we are culturally-trained to believe that it’s much easier to extract information from a picture than from text. But upon testing this belief (p-prim, for those in the know), I found that contrary to the notion “a picture is worth a thousand words,” it’s much more difficult to get data from an illustration than from a story. While emotional impact might be larger with a picture, it’s not true for comprehension. You can read the results of my study at http://www.pipsqueak.com/pages/papers.html “Visual Symbolic Processing in Modern Times” paper presented at AACE ED-MEDIA Conference in 2008. Since then, I’ve collected more data, and the results are similarly aligned: problem-solving requiring higher level visual symbolic processing skills is difficult and results in communication failures. A secondary, and surprising, finding was a gender discrepancy in performance outcome testing of visual symbolic processing skills. Higher level and lower level visual symbolic processing are defined in the paper. And anyone interested in testing their visual processing skills are welcome to…

More is Better: Why iPad doesn’t Satisfy Everyone

by  • 

Swiss Army iPad

There have been a lot of complaints flying around about how iPad doesn’t do this, and iPad can’t do that, and iPad won’t work with that other thing. Some people are so obsessed about all the things that iPad isn’t capable of doing that they overlook all that it can do. By looking for failure, these reviewers lost sight of what iPad is all about. There are plenty of people who are defending iPad out there, so I was interested in why the people who dislike iPad so passionately feel the way they do. We, the people, tend to make our decisions based on little snippets of information that we find to be true and productive for solving various problems. “If something is steaming, it must be hot.” “Big things fall harder and faster.” “Where there’s smoke, there’s fire.” “If one is good, two is even better.” “If it looks clean…” “Little kids don’t lie.” “If it’s natural, it’s not chemical.” “Summer is when the Earth is closest to the sun.” “One can’t get fat eating vegetables.” These are the building blocks of our intuitions. We are all walking encyclopedias of folksy wisdom—common sense explanations that are consciously and unconsciously…
