RE: Tracing the Spark of Creative Problem-Solving

by  • 

Article:  Carey, B. (2010). “Tracing the Spark of Creative Problem-Solving.” nytimes.com. Visited on October 29th, 2012: http://www.nytimes.com/2010/12/07/science/07brain.html Summary:  Puzzles come in a wide variety of formats. They are appealing to people both because of the dopamine rush of arriving at a solution, and also because they shift the brain into an open, playful state. Puzzles are solved in two main ways — either through insight thinking or analytical thinking.  Insight thinking is when an answer comes to a person suddenly, seemingly out of the blue. Analytical thinking involves employing a systematic approach of testing available possibilities. Both types of thinking are typically required to solve challenging problems. The differences between the two approaches have been debated by scientists, but current experiments and brain-imaging studies indicate that they are separate abilities requiring truly different brain states. Test subjects are more likely to solve puzzles using insight thinking when they display brain activity in the anterior cingulate cortex. This activity is associated with the widening of attention, making the brain more open to distraction and to detecting weaker connections. Positive mood appears to shift the brain towards the state required for insight thinking. In experiments where subjects are shown a humorous video…

Haptics and the Uniformity of Gloss

by  • 

For an introduction into the science of haptics, the article, “Primal, Acute and Easily Duped: Our Sense of Touch,” provided great examples about the accuracy and fallibility of our sense of touch. However, the proliferation of touch-sensitive input devices over the past 4 years since it was written didn’t provide the author with any insight into their pending popularity, or the effect they would have on our fingertips. If our fingertips can feel a bump the thickness of one micron, imagine the sensitivity they have even as they slide over a touch-sensitive glass tablet, a glossy plastic mouse, or an anodized smooth track pad. The more our fingertips are required to touch, drag, swipe, and pinch, even over smooth surfaces, the more abrasive those surfaces become over time and the more those subtle abrasions wear on our skin. Glass becomes scratched, plastic becomes scuffed, and biological stains build up on anodized aluminum along with all other surfaces. The point being that these smooth surfaces end up hurting, if not annoying, our fingertips over time. If the fingertips are the equivalent of the fovea of our eyes, why subject ourselves to these increasingly painful disturbances and not return to using an…

RE: Deadline Pressure Distorts Our Sense of Time

by  • 

Article:  Herbert, W. (2011). “Deadline Pressure Distorts Our Sense of Time.” scientificamerican.com. Visited on October 9th, 2012: http://www.scientificamerican.com/article.cfm?id=looming-deadlines Summary:  The perceived difficulty and deadline pressure associated with a task alters our perception of time. In an initial study, subject were presented with a series of tasks of varying difficulty and asked how far away the day of completion felt to them. The tasks that were more complex and work intensive were perceived as being further in the future. To arrive at this result our brains are translating effort into time, assuming that the more difficult tasks must be further away since they will require more work to complete. An opposite effect is encountered when deadlines are associated with the tasks. If subjects are presented with either an easy or difficult task that they must complete by a set date in the future, those with the more complex and effortful task report that the date feels much closer to them than those with the simple task. This effect may sometimes cause us to feel overwhelmed as multiple complex tasks pile up on us, but our skewed perception of time also ensures that we typically complete necessary tasks within the actual amount of time…

Define your terms: What is sex?

by  • 

The article, “Sex Makes You Smarter — Can ‘Virtual Sex’ Do The Same?” was a great example of either knowing your audience too well or over-using jargon. The most prevalent problem in it was the lack of defined terms. The author assumed that the reader knew terms like: neurogenesis, glucocorticoid levels, and dendritic architecture (a case of cognitive blindness). But the biggest failure was the author’s negligence to define the most basic term about which the article was written: sex. What is sex? Who is having it? How are they having it? These questions were unanswered. The research on which the article was based indicated that male rats were the subject of the study and were “exposed” to sexually-receptive female rats. That was it. That was the only definition of sex in the entire article, and it was a very vague definition, especially if one extrapolated it to the realm of human sex, which is known to be complicated and varied. Is the author talking about the sexual gratification of males only? If sex was a form of exercise, as the author explained it was, how much caloric effort should the male engage in to achieve it or what heart rate should…

We Are 80% Optimistic

by  • 

Gallagher, James, (2011). “Brain ‘rejects negative thoughts’.”  BBC.co.uk. Visited on October 8, 2012: http://www.bbc.co.uk/news/health-15214080 This article, “Brain ‘rejects negative thoughts’”, speaks of a generalized view of the brain based on evidence gathered from a wide population. Optimists, or those whose frontal lobes process good news and comparatively ignore bad news, make up about 80% of the population; while the remaining 20%, the pessimists, have a similar predisposition to bad news. Since optimists do not absorb bad news, risks are often underestimated; as a population, it can be generalized to say that the people respond more to good news than to bad. Conceptual Design: If risks are to be acknowledged and people’s views changed to reflect them, information regarding them should be emphasized. Information with positive effect will be more attractive, and need not be emphasized for message to be processed. Knowledge of this could be particularly useful in government. Knowing this, in sales, information may be designed which downplays risks, and emphasizes positive attributes, for maximum acceptance of the product in a general population. Furthermore, a population whose predilection is to pessimism could be acknowledged with information products designed specifically for them. Interaction Design: Elements of the product may be…

Who Controls Social Networks?

by  • 

Article: Bohannon, J. (2012). “Who Controls Social Networks?” sciencemag.org. Visited on Oct 9, 2012:http://news.sciencemag.org/sciencenow/2012/06/who-controls-social-networks.html This article is about how ideas spread in social groups through peer influence. A theory long debated is that a small number of people who are influencers spread ideas through their peer groups. Critics of the theory argue that is it not how much influence these people have but how susceptible to the new idea people are. The study of peer influence has proven difficult to conduct, but the rise of social networks such as Facebook provide a means for researchers to study a large number of people. One study in the article found that on Facebook there was a clear divide between influencers and those that were susceptible to new ideas. Conceptually, it’s important for any product developer to understand who their product’s influencers are if they wish their product to spread through peer influence. The article suggests that the personality traits of people affect influence. Examples: Women influence men more than women. People over 30 were more influential than those under 30. The article states that the most important finding is that Influencers and those who are susceptible are not traits found within the…

RE: Go Figure: Why we think rituals can influence results

by  • 

Article: Blastland, M. (2011). “Go Figure: Why we think rituals can influence results.” bbc.co.uk. Visited on October 9th, 2012: http://www.bbc.co.uk/news/magazine-14917871 Summary: Humans have a strong capacity for pattern recognition. This is beneficial in many circumstances, aiding in our survival and helping us safely navigate our environment. However, the same cognitive mechanisms can also cause us to make incorrect associations between cause and effect. One example is a sports fan believing that a ritual like wearing “lucky” socks during an event will increase the chances of success for their favorite team. In statistics this over-interpretation of random events and correlations is known as a Type I error. The same type of behavior can be seen in animal studies, where pigeons will repeat an action that they have incorrectly assumed is the cause of food being delivered to them, when the timing was actually random. Conceptual Design: When designing a new product are we utilizing our users’ strength for pattern recognition?  Often humans can tease complex patterns from noisy data far more effectively than computers.  Can users effectively see the link between using our product and having the positive outcomes that they desire? If our product has benefits, we would definitely like our users…
