Want to solve a particularly vexing problem? Try using your hands when formulating solutions.

3rd and 4th grade children told to move their hands when explaining how they’d solve a problem were four times as likely as kids given no instructions to manually express correct new ways to solve problems. Even though they didn’t, in the end, give the right answer, their gestures revealed an implicit knowledge of mathematical ideas. For example, to indicate the need for the sides to be equal, children might sweep the palm first under a problem’s left side and then under its right side. Although those children weren’t ready to turn that implicit knowledge into action (at that point they solved problems incorrectly), a second study showed that gesturing set them up to benefit from subsequent instruction.

In that study, the researchers assessed how gesture vs. no-gesture students performed after subsequent instruction in how to solve the math problems. At post-test, children who’d been told to gesture about math problems and then had a lesson solved 1.5 times more problems correctly as did the children who’d been told not to gesture – a significant advantage.

Feeling and seeing belong together. I’ve said so for years.

From Philosophical Transactions of the Royal Society B – abstract (my clarifying additions):

People see with feeling (something I’ve been saying for 20 years). We ‘gaze’, ‘behold’, ‘stare’, ‘gape’ and ‘glare’. In this paper, we develop the hypothesis that the brain’s ability to see in the present incorporates a representation of the affective (emotional) impact of those visual sensations in the past (meaning you don’t actually “see” – you FEEL + SEE). This representation makes up part of the brain’s prediction of what the visual sensations stand for (meaning = emotion+visual stimulus) in the present, including how to act on them in the near future (based on how we feel about what we see, we act accordingly). The affective prediction (emotional interpretation) hypothesis implies that responses signalling an object’s salience, relevance or value do not occur as a separate step after the object is identified (seeing = FEELING + SENSUAL INPUT). Instead, affective (emotional) responses support vision from the very moment that visual stimulation begins.

You see AND feel – never see alone. Your visual signals pass through and interact with the emotional parts of your brain – so OF COURSE you’d attach feeling to visual stimulus. I’ve said it for many years and every Rapid Eye Technician knows it from experience. Nice to see that someone is considering doing some solid science about our hypothesis and experience.

Americans – ready to work for better educated FOREIGNERS – as their janitors, factory workers, and house cleaners? Good thing we at least know we’re free (from choice)! The solution to the dumbing of America is so easy it hurts – just attach education money to the student – instead of the current system of funding school districts regardless of performance – and let good old-fashioned American competition do the rest. I’m confident it will work. We just have to be brave enough to say no to powerful teachers unions and bought and paid-for politicians. If you’re an American, I hope this video scares the hell out of you – enough to move you to action.

We don’t need more police in our schools – we need a new school system. When schools compete, you win!

A wealth of evidence has shown that small amounts of carbon dioxide can provoke a panic attack (PA) in certain anxiety-prone individuals.

The Public Library of Science (PLoS ONE) recently published a study showing that inhalation of carbon dioxide (CO2) triggers emotional distress and a panic response in healthy people. The researchers wonder if panic is an inborn survival-oriented response. The results may better our understanding and help prevent some emotional disorders.

A wealth of evidence has shown that small amounts of carbon dioxide can provoke a panic attack (PA) in certain anxiety-prone individuals – like those diagnosed with panic disorders (PD). Panic may be an inborn behavioral response to a metabolic distress – like the triggering of a CO2 level monitor in the brain.

To test whether CO2 effectively controls emotional states, the research team of the Academic Anxiety Center at the University of Maastricht, the Netherlands (Griez et al) conducted a study in healthy volunteers breathing increasing amounts of CO2.
