Metacognition Failure: If I find it easy, it must not be important

by  • 

Making something easy to understand is extremely difficult. A good designer knows this, knows how hard one has to work to make something comprehensible and easy to use. Unfortunately, users and consumers of products (including education) tend not to get it. We live in society ruled by “More is Better” p-prim: more stuff is better, more money is better, more food is good, more medication is great…more, more, more. Movies, television, newspapers, magazines, all reinforce this idea in our minds. We live in a “super-size me” world. But this basic decision-making algorithm leads to very faulty reasoning. There are multiple corollaries to the “more is better” axiom: thick books without graphics are more educationally valuable, more important (this is based on research I did many years ago with 5th graders); longer essays are clearly better and should get higher graders (the students worked harder/longer on them); big words are better than small ones in expressing ideas (thus we get very pretentious writing); work should be judged by the time it took to complete and not by the quality of the results it produces; more expensive clothes (cars, stereos, etc.) are clearly more valuable (this is a true statement, but most…

Male Paternal Bonds

by  • 

Angier, N., (2010). “Paternal Bonds, Special and Strange.” Nytimes.com. Retrieved on 20 June 2010: http://www.nytimes.com/2010/06/15/science/15fath.html?_r=1 An article written by, Natalie Angier in the New York Times, Paternal Bonds, Special and Strange, begins by stating how men are proudly proclaiming the number of children they have to other men. Comparisons are made between humans and other primates such as monkeys that also proudly display their infants to impress other male monkeys. It is stated that this action is done to strengthen the bonds between men. Furthermore, the article discusses multiple studies that demonstrate how male primates care for their offspring. For example, some bird species are the sole keeper of their nest. The article aims to link parental care and offspring welfare. One study claims that baby handling can demonstrate how fathers can take charge, beat the odds, and expand the nest. The studies referenced provide examples of what the author calls, “dream daddies” and males “behaving dadly”. Conceptual Design Through this study we can see that male animal primates have an instinctual response to care for and flaunt their offspring. This appears to a revolutionary breakthrough in our understanding of linking men with caring giving. The biological and innate instincts…

A Curiously French Complaint

by  • 

Kirby, E. (2008). “ A Curiously French Complaint,” BBC News.  Retrieved on 2008/12/13. http://news.bbc.co.uk/go/pr/fr/-/2/hi/programmes/from_our_own_correspondent/7779126.stm Summary: This article focuses on the cultural differences between the French and British populations in regards to their medical care. Each culture has their own script of understanding, which people rely to set their expectations during a medical crisis. The author Emma experienced a cultural ‘shock’ during her first encounter with a French doctor due to her vastly different set of expectations. She visits a doctor in France due to the severity of a sore throat, where she is “diagnosed with a severe lung infection, mild asthma and had in my hand a prescription for six different types of medicine, an appointment at the local hospital’s radiology department and an emergency referral to a specialist in pulmonary disease (article).” Upon her return to Britain a few days later, she visits her family physician, who within a few minutes diagnoses her with only a ‘common cold.’ Her article then explains how the French expect a much more sever diagnosis to support their physical suffering. France is also the leading country of consumers who take prescription medications. While in England, there’s a more ‘keep a stiff upper lip’…

Working Memory Limitations vs. the Size of Problem

Three BLind Men and an Elephant Proverb

The illustration above comes from Wikipedia, which has a complete entry on the Asian proverb about blind monks who examine an elephant and generate multiple hypotheses of what it could be. In product design speak, these monks are doing collaborative problem solving with a shared goal of identifying a mysterious object—the elephant. The monks, the story goes, all come from different backgrounds: an old tailor touching an elephant’s ear describes it as cloth; an aging gardner hugging the leg imagines a tree trunk; an elephant’s tusk is envisioned as a weapon by an arms master. Each monk brings his own life’s worth of experience to bear on the problem, but each has very limited access to the whole. It’s easy to see how this story can be used to explain the pains of collaborative and cooperative group projects in which individuals focus on product design. Each person brings their own expertise to the table, hopefully contributing positively to the whole process. But this story is also a good metaphor for understanding problem solving in context of our very limited working memory capacity. Unlike elementary school math problems that we all calculated, real world problems are messy and don’t come with…
