How the Brain Learns

Researchers study timing, sensory systems, how regions connect

“Important cognitive skills, such as attentional control, may be closely related to the capacity to maintain rhythmic synchrony within a group, an ability that music trains in unique ways,” Chiba says. 

Cottrell says the idea for the study originated with Khalil’s observation of students in his elementary school music class, where he was teaching Gamelan.  “He had a dozen kids playing instruments, and they were supposed to be doing it exactly in time with each other,” Cottrell says.  “He noticed there were some kids who were having a lot of trouble with this, and they tended to be the kids with ADD (attention deficit disorder).  He wondered whether teaching these kids Gamelan might improve their attention skills in general, so the Gamelan Project was born.”

Other center research includes, among other things, studying whether training autistic children to become “face experts” will improve their social skills; trying to develop robots trained to “read” a student’s facial expressions in order to improve intelligent tutoring systems; and figuring out how brains change as people become experts at perceptual skills, such as scanning for explosives in suitcases.

The scientists believe that a better understanding of the role of time and timing on scales ranging from milliseconds (when brain cells connect) to years (the time it takes to become an expert) potentially could transform education, “giving children a better chance of success in school, and, ultimately, in life,” Cottrell says.

As we learn we learn!( exposure thru the olfactory system...

If you divide increments in acquired knowledge by the the time it takes to gain that incremental knowledge, you get the rate of learning.

If you then divide changes in the rate of learning by the time interval, you get what mathematicians would call the second derivative of the learning curve. What is the second derivative? When it's negative, the learning curve is concave -- slowing or curving downward. When it's positive, the learning curve is convex -- accelerating or curving upward.

But how does the learner experience that degree of positive or negative curvature of the learning curve?

One model says we experience it as perturbations in our affective emotional state -- anxiety vs confidence, boredom vs fascination, dispirited vs enthused, fearful vs courageous, embarrassed vs prideful.

Interesting article reminds me of two things:

1) the "spiral" learning math texts/workbook used in my son's Challenge class over the years, good at introducing new concepts and revisiting others over the life of the course.

2) my own middleschool social studies final exam, based solely on prior tests which I aced, yet some how I bombed it because I only reviewed the few questions I had missed that semester - assuming I would remember the rest, and didn't well enough after not seeing for months. Timing indeed matters.
