A blessing, not a curse: Experimental evidence for beneficial effects of visual aesthetics on performance - Ergonomics

  • Thus, in contrast to the notion that visual aesthetics may worsen performance, visual aesthetics even compensated for poor usability by speeding up task completion.

Museum 2.0

  • the rubric of participatory models introduces a language that can be useful to many kinds of institutions and projects.
  • In citizen science projects, the public is invited to participate in "real science" by working with scientists on projects that benefit from mass participation around the world. But most citizen science projects are contributory; participants collect data based on specifications determined by scientists, to help answer questions posed by scientists. The scientists control the process, steer the data collection, and analyze the results. Unsurprisingly, studies have shown that these kinds of citizen science projects are enormously successful at engaging the public with science but are not successful at exposing participants to the entire scientific process.

Virtual Worlds May Be the Future Setting of Scientific Collaboration

  • Normally, virtual worlds are the setting of many online games and entertainment applications, but now they’re becoming a place for scientific collaboration and outreach, as well. A team of scientists from the California Institute of Technology, Princeton, Drexel University, and the Massachusetts Institute of Technology have formed the first professional scientific organization based entirely in virtual worlds. Called the Meta Institute for Computational Astrophysics (MICA), the organization conducts professional seminars and popular lectures, among other events, for its growing membership.

The human brain is on the edge of chaos

  • the dynamics of networks have something important in common with some superficially very different systems in nature. Computational networks showing these characteristics have also been shown to have optimal memory (data storage) and information-processing capacity. In particular, critical systems are able to respond very rapidly and extensively to minor changes in their inputs.

  • I think the financial crisis has helped expose a powerful bias in human decision-making, which is our abhorrence of uncertainty. We hate not knowing, and this often leads us to neglect relevant information that might undermine the certainty of our conclusions. I think some of the most compelling research on this topic has been done by Colin Camerer, who has played a simple game called the Ellsberg paradox with subjects in an fMRI machine. To make a long story short, Camerer showed that players in the uncertainty condition - they were given less information about the premise of the game - exhibited increased activity in the amygdala, a center of fear, anxiety and other aversive emotions. In other words, we filled in the gaps of our knowledge with fright. This leads us to find ways to minimize our uncertainty - we can't stand such negative emotions - and so we start cherry-picking facts and forgetting to question our assumptions.
