I have been thinking about creating a new memory palace for myself. So from time to time I may post about this project. Here is a video on the memory palace technique:

Education Secretary increases investment in questionable neurofeedback company

31 Jul

According to Politico:

Education Secretary Betsy DeVos has increased her financial stake in a “neurofeedback” company that says its technology treats attention deficit disorder and the symptoms of autism. DeVos reported a new investment of between $250,001 and $500,000 in the Michigan-based Neurocore, according to a financial disclosure form that was certified by government ethics officials on Wednesday.

The whole story is here (scroll down to find the story). For background on Neurcore read this.

Taking photos affects memory

14 Jul

Taking a cell phone photograph in a convenient way to store information for later retrieval. Many people take photos to remember their parking places and I have, on occasion, photographed the cover of a book in a library, so that I could order a copy later. But but does taking pictures affect a memory?

Yes, says a paper in the most recent Psychological Science.  It seems to improve our visual memory for specific information, but degrades our audio memory. Here is the abstract:

How does volitional photo taking affect unaided memory for visual and auditory aspects of experiences? Across one field and three lab studies, we found that, even without revisiting any photos, participants who could freely take photographs during an experience recognized more of what they saw and less of what they heard, compared with those who could not take any photographs. Further, merely taking mental photos had similar effects on memory. These results provide support for the idea that photo taking induces a shift in attention toward visual aspects and away from auditory aspects of an experience. Additional findings were in line with this mechanism: Participants with a camera had better recognition of aspects of the scene that they photographed than of aspects they did not photograph. Furthermore, participants who used a camera during their experience recognized even nonphotographed aspects better than participants without a camera did. Meta-analyses including all reported studies support these findings.

The importance of committing facts to memory

19 May

In an article in last week’s New York Times, we find this:

The director of Google’s education apps group, Jonathan Rochelle, touched on that idea in a speech at an industry conference last year. Referring to his own children, he said: “I cannot answer for them what they are going to do with the quadratic equation. I don’t know why they are learning it.” He added, “And I don’t know why they can’t ask Google for the answer if the answer is right there.”

Regular readers know that I think this fundamentally misguided. Knowledge remains and will remain essential to negotiating the world. To see why let’s turn to another article in the Times: “If Americans Can Find North Korea on a Map, They’re More Likely to Prefer Diplomacy.”

Here’s the map of where the surveyed individuals placed North Korea.

According to the Times:

Geographic knowledge itself may contribute to an increased appreciation of the complexity of geopolitical events.

By the way the quadratic equation is not that hard to learn.
