(Truthfully they\u2019re important in life, but that broader range lies outside of this blog\u2019s focus.)<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Today\u2019s News<\/h2>\n\n\n\n<p>I recently saw an enthusiastic response to a <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0273229724000522\" target=\"_blank\" rel=\"noopener\">newly-published study<\/a> that explores,&nbsp; reconceptualizes &#8212; and debunks? &#8212;&nbsp; EFs. Because EFs \u201care mightily important,\u201d such reconceptualization &amp; debunkage merits our thoughtful attention.<\/p>\n\n\n\n<p>Here\u2019s the story.<\/p>\n\n\n\n<p>A research team led by Andreas Demetriou wanted to see if they could translate that long list (\u201cprioritizing, switching, evaluating,\u201d etc.) into a core set of mental processes.<\/p>\n\n\n\n<p>So: a carbon atom might look different from an iron atom, but both are different ways of putting protons, neutrons, and electrons together. Likewise, \u201cprioritizing\u201d and \u201cswitching\u201d might seem like two different processes, but they could instead be different arrangements of the same mental elements.<\/p>\n\n\n\n<p>Demetriou\u2019s team focuses on two core mental processes \u2013 their \u201cprotons and electrons.\u201d Roughly, those mental processes are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Forming and holding a <em>mental model of the goal<\/em>, and<\/li>\n\n\n\n<li><em>Mapping<\/em> that mental model onto the situation or problem.<\/li>\n<\/ul>\n\n\n\n<p>For complicated reasons, Team D combines these two processes with a label: the&nbsp;<strong>AACog mechanism<\/strong>. They then run a lengthy series of studies using a GREAT variety of different tests (Stroop this, Raven\u2019s that) across a wide range of ages.<\/p>\n\n\n\n<p>When they run all the calculations, sure enough: the AACog mechanism underlies all those other EFs we\u2019ve been taught about over the years.<\/p>\n\n\n\n<p>As they write: \u201cAACog is the common core running through all executive functions.\u201d (That\u2019s an extraordinary claim, no?)<\/p>\n\n\n\n<p>And, <em>development <\/em>of the AACog mechanisms explains all sorts of increasing mental capacities: symbolic exploration, drawing inferences, using deductive reasoning, and so forth. (The concentric circles representing this argument challenge all of my AACog mechanisms!)<\/p>\n\n\n\n<p>In other words, this model explains an ENORMOUS amount of human cognitive processing by focusing on two elements.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What It All Means<\/h2>\n\n\n\n<p>I wrote above that this study received an \u201centhusiastic response\u201d when it came out.<\/p>\n\n\n\n<p>In my twitter feed at least, it was packaged with basically this message:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>\u201cAll those people who were nattering on about EF were having you on. Look: we can boil it down to basically one thing. No need to make it so complicated!\u201d<\/p>\n<\/blockquote>\n\n\n\n<p>I can understand why Twitter responded this way: the title of the Demetriou et al. study is: &#8220;Executive function: Debunking an overprized construct.&#8221; No wonder readers think that the idea of EFs has been debunked!<\/p>\n\n\n\n<p>At the same time, I&#8217;m not so sure. I have three reasons to hesitate:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">First:<\/h3>\n\n\n\n<p>Quoth Dan Willingham: &#8220;One study is just one study, folks.&#8221; Until MANY more people test out this idea is MANY more ways, we shouldn&#8217;t suddenly stop thinking one thing (&#8220;EFs exist!&#8221;) and start thinking another (&#8220;EFs are the AACog mechanism in disguise!&#8221;).<\/p>\n\n\n\n<p>We need more research &#8212; LOTS &#8212; before we get all debunky.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Second:<\/h3>\n\n\n\n<p>Let&#8217;s assume for a moment that the AACog mechanism hypothesis is true. What effect will that have on discussions in schools?<\/p>\n\n\n\n<p>Honestly, I doubt very much.<\/p>\n\n\n\n<p>The &#8220;AACog mechanism&#8221; is itself so abstract &#8212; as are the &#8220;modeling&#8221; and &#8220;mapping&#8221; functions that go into it &#8212; that I doubt they&#8217;ll usefully replace &#8220;exective functions&#8221; in daily conversations.<\/p>\n\n\n\n<p>Imagine that a learning specialist says to me: <em>&#8220;This student has a diagnosed problem with her AACog mechanism.&#8221; <\/em><\/p>\n\n\n\n<p>I&#8217;ll probably respond: <em>&#8220;I don&#8217;t understand. What does that mean?&#8221;<\/em><\/p>\n\n\n\n<p>The learning specialist will almost certainly respond: <em>&#8220;Well, she has difficulty with prioritizing, task switching, initiating, and so forth.&#8221;<\/em><\/p>\n\n\n\n<p>We&#8217;re back to EF language in seconds.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Third:<\/h3>\n\n\n\n<p>I&#8217;m not sure I buy the argument that the &#8220;AACog mechanism&#8221; DEBUNKS &#8220;executive function.&#8221;<\/p>\n\n\n\n<p>Imagine this logical flow:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Carbon and iron are made up of the same sub-elements: protons, neutrons, and electrons.<\/li>\n\n\n\n<li>Therefore, carbon and iron don&#8217;t really exist.<\/li>\n\n\n\n<li>Voila: we&#8217;ve debunked the idea of carbon and iron.<\/li>\n<\/ul>\n\n\n\n<p>Well, that logic just doesn&#8217;t hold up. Carbon and iron DO exist, even as meaningfully different arrangements of sub-particles.<\/p>\n\n\n\n<p>So too:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>EFs all boil down to the AACog mechanism, which is itself just &#8220;mental modelling&#8221; and &#8220;mapping of models onto reality.&#8221;<\/li>\n\n\n\n<li>Therefore, EFs don&#8217;t really exist.<\/li>\n\n\n\n<li>Misson Debunk Accomplished!<\/li>\n<\/ul>\n\n\n\n<p>I just don&#8217;t track that logic.<\/p>\n\n\n\n<p>We <em>understand human cognitive complexity better<\/em>, but the <em>complexity hasn\u2019t gone away<\/em>. (We understand carbon and iron better now that we know about protons and neutrons, but the periodic table is still complicated.)<\/p>\n\n\n\n<p>This model helps us think differently about mental functions across academic disciplines. Those new thought patterns might indeed be helpful &#8212; especially to people who create conceptual diagrams of cognition.<\/p>\n\n\n\n<p>But I don&#8217;t think it will radically change the way teachers think and talk about our students.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">TL;DR<\/h2>\n\n\n\n<p>A group of thoughtful scholars have put together a new model of cognition explaining executive functions (and a whole lot more).<\/p>\n\n\n\n<p>What does this mean for us?<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>In ten or fifteen years, EF experts might be talking to us differently about understanding and promoting these cognitive moves.<\/li>\n\n\n\n<li>In the meantime, don&#8217;t let oversimplications on the interwebs distract you. Yes: &#8220;executive function&#8221; is a mushy and complicated category &#8212; and yes, people do go too far with this label. But something like EFs exist, and we do need to understand their complexity.<\/li>\n<\/ol>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p>Demetriou, A., Kazali, E., Spanoudis, G., Makris, N., &amp; Kazi, S.
