The last time I went through my flashcard deck, I got all of those new words right. Should I keep studying? Or, is it time to move on to my Algebra?<\/p>\n<p>In a recently published <a href=\"http:\/\/www.nature.com\/neuro\/journal\/v20\/n3\/full\/nn.4490.html\">paper<\/a>, Shibata and colleagues argue that <em>overlearning<\/em> benefits long-term memory formation. That is: <span style=\"text-decoration: underline;\">I should keep studying<\/span>, because that extra level of work &#8212; above and beyond what&#8217;s required to get all my flashcards correct &#8212; protects these new memories from later interference.<\/p>\n<p>(If you want the neurotransmitter details, Shibata finds that overlearning, which he calls &#8220;hyperstabilization[,] is associated with an abrupt shift from glutamate-dominant excitatory to GABA-dominant inhibitory processing in early visual areas. Hyperstabilization contrasts with passive and slower stabilization, which is associated with a mere reduction of excitatory dominance to baseline levels&#8221; p. 470. Got that?)<\/p>\n<p>And yet, there&#8217;s a reason I put that question mark in the title of this article. Earlier researchers have found that overlearning <em>just doesn&#8217;t work<\/em>. (Doug Rohrer and Hal Pashler have published on this topic\u00a0<a href=\"http:\/\/escholarship.org\/uc\/item\/6061k9j5\">here<\/a>\u00a0and\u00a0<a href=\"http:\/\/www.pashler.com\/Articles\/Pashler.Rohrer.Cepeda.Carpenter_2007.pdf\">here<\/a>.)<\/p>\n<p>For the time being, I&#8217;m inclined to believe Rohrer and Pashler. Why? Because Shibata&#8217;s research paradigm showed a <em>change in neuotransmitters<\/em> after <strong>2 days<\/strong>. Rohrer and Pashler&#8217;s paradigm showed <em>no benefits for learning<\/em> after <strong>1 month<\/strong>.<\/p>\n<p>In my view, teachers ought to be more interested in <span style=\"text-decoration: underline;\">learning<\/span> than in <span style=\"text-decoration: underline;\">GABA and glutamate<\/span>; and we ought to be less impressed by results obtained after <span style=\"text-decoration: underline;\">48 hours<\/span> than by results obtained after <span style=\"text-decoration: underline;\">4 weeks<\/span>.<\/p>\n<p>(To be clear: I am interested in neurotransmitters. But, as a teacher, I&#8217;m MUCH more interested in demonstrated learning.)<\/p>\n<p>So, for the time being, I&#8217;m will continue to recommend that students and teachers not emphasize overlearning. However, I will add an asterisk to that advice: as of today, our understanding of the neural results of overlearning is far from complete.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I&#8217;m reviewing the vocabulary I learned in today&#8217;s Spanish class.
