It\u2019s arguably the most important issue in educational psychology. After all, we spend years in the classroom. One would hope the things we learn make us more productive on the job, conscientious as citizens or intelligent in our daily lives.<\/p>\n<p>Yet it turns out the titular question is really difficult to answer. This is because the answer depends on three different questions, each of which is itself incredibly complicated:<\/p>\n<ol class=\"wp-block-list\">\n<li>How do we perform skills?<\/li>\n<li>How do we acquire them?<\/li>\n<li>What sorts of skills are used in real life?<\/li>\n<\/ol>\n<p>About two years ago, I started a research project to learn everything I could about transfer. It quickly became clear that understanding transfer depended on answering the other three questions, so my research broadened drastically.<\/p>\n<p>Despite two years of research and a lot of writing about transfer (including a chapter of <a href=\"https:\/\/www.scotthyoung.com\/blog\/ultralearning\/\">my book<\/a>), I still don\u2019t have a definitive answer for how much transfer we can expect. But I\u2019d like to share at least how I\u2019ve come to think about the issue.<\/p>\n<h2 class=\"wp-block-heading\">Question One: How Do We Perform Skills?<\/h2>\n<div class=\"inline-podcast\">\n<small>Listen to this article<\/small><br \/>\n<iframe loading=\"lazy\" width=\"100%\" height=\"20\" scrolling=\"no\" frameborder=\"no\" allow=\"autoplay\" src=\"https:\/\/w.soundcloud.com\/player\/?url=https%3A\/\/api.soundcloud.com\/tracks\/1534327468%3Fsecret_token%3Ds-juyTV0wYgXx&#038;color=%23219895&#038;inverse=false&#038;auto_play=false&#038;show_user=true\"><\/iframe><\/div>\n<p>Essentially, transfer is a product of overlap.

What differs between theories is the \u201csomething\u201d which potentially overlaps. Let\u2019s consider some candidates:<\/p>\n<ul class=\"wp-block-list\">\n<li><strong>Broad mental faculties.<\/strong> In <a href=\"https:\/\/dictionary.apa.org\/formal-discipline\">this framework<\/a>, \u201creasoning\u201d or \u201cmemory\u201d overlap across different skills. This theory likens the mind to a muscle that can be strengthened through many types of practice. This would suggest transfer is quite broad and that almost any strenuous mental activity should produce benefits.<\/li>\n<li><strong>Stimulus-response.<\/strong> Perhaps, per the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Behaviorism\">behaviorists<\/a>, the mind is merely a collection of habits, stimulus leading inevitably to response? This view would suggest transfer is extraordinarily limited\u2014every superficial change in a situation would require a new skill.<\/li>\n<li><strong>Propositions and productions.<\/strong> Theories like <a href=\"https:\/\/www.scotthyoung.com\/blog\/2022\/02\/15\/act-r\/\">ACT-R<\/a> argue that our brains store skills in essentially two forms: small chunks of factual knowledge and simple component procedures. Complex skills and knowledge are simply aggregates of these foundational pieces.<\/li>\n<li><strong>Schemas.<\/strong> <a href=\"https:\/\/en.wikipedia.org\/wiki\/Schema_(psychology)\">Schema-based theories<\/a> claim that knowledge is organized in patterns larger than individual actions or chunks. These patterns roughly correspond to \u201ctemplates\u201d with both fixed and variable components. For instance, we might have a \u201cbirthday party\u201d schema that includes birthday cake and presents, but only optionally clowns or pointy paper hats.<\/li>\n<li><strong>Neural networks.<\/strong> The brain is made out of neurons, and we have some idea of how those neurons process information. <a href=\"https:\/\/en.wikipedia.org\/wiki\/Connectionism\">Connectionist<\/a> theories take these basic neuronal properties as a starting point and posit theories of learning based on them. Teasing out implications for transfer is harder here, but it would most likely look like an overlap in the synaptic connectivity between two skills.<\/li>\n<li><strong>Activity systems.<\/strong> Perhaps transfer isn\u2019t in our heads but is a property of our <a href=\"https:\/\/en.wikipedia.org\/wiki\/Situated_cognition\">broader social and physical environments<\/a>? In this view, the person relies on their environment to perform a skill, and transfer fails when those environmental supports are altered.<\/li>\n<\/ul>\n<p>Only the first two seem to be demonstrably false. The <a href=\"https:\/\/www.scotthyoung.com\/blog\/2022\/09\/13\/brain-training-doesnt-work\/\">mind is not like a muscle<\/a>, nor is it a simplistic stimulus-response device.<\/p>\n<p>I find the information-processing perspective of cognitive science to be the most persuasive. The mind is essentially computational (although quite different from computers made out of transistors). Answering the question of transfer depends on how the algorithms for skills are composed.<\/p>\n<p>From this perspective, what seems safe to say is that skills can only reliably influence each other if they overlap in either their procedures or knowledge. If two skills don\u2019t use the same process, and the knowledge they depend on is different, there shouldn\u2019t be much (if any) transfer.<span id='easy-footnote-1-15058' class='easy-footnote-margin-adjust'><\/span><span class='easy-footnote'><a href='https:\/\/www.scotthyoung.com\/blog\/2023\/04\/18\/skill-transfer-explained\/#easy-footnote-bottom-1-15058' title='I\u2019m leaving aside analogies. Analogies suggest two domains that have nothing to do with each other may actually be a source of transfer. But another way of saying this is that analogies suggest an abstract commonality between two superficially different domains. When analogies are useful, they tend to share an overlapping deep structure, so I would include them as an &amp;#8220;overlap&amp;#8221; theory, even if the overlap is an active process rather than the nature of the mental representations themselves.'><sup>1<\/sup><\/a><\/span><\/p>\n<h2 class=\"wp-block-heading\">Question Two: How Do We Acquire Skills?<\/h2>\n<p>How the mind represents skills is only one part of understanding transfer. There\u2019s also the issue of how we acquire these representations.<\/p>\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"512\" src=\"https:\/\/www.scotthyoung.com\/blog\/wp-content\/uploads\/2023\/04\/How-Much-Transfer-Between-Skills2-1024x512.jpg\" alt=\"\" class=\"wp-image-15069\" srcset=\"https:\/\/www.scotthyoung.com\/blog\/wp-content\/uploads\/2023\/04\/How-Much-Transfer-Between-Skills2-1024x512.jpg 1024w, https:\/\/www.scotthyoung.com\/blog\/wp-content\/uploads\/2023\/04\/How-Much-Transfer-Between-Skills2-300x150.jpg 300w, https:\/\/www.scotthyoung.com\/blog\/wp-content\/uploads\/2023\/04\/How-Much-Transfer-Between-Skills2-768x384.jpg 768w, https:\/\/www.scotthyoung.com\/blog\/wp-content\/uploads\/2023\/04\/How-Much-Transfer-Between-Skills2-1536x768.jpg 1536w, https:\/\/www.scotthyoung.com\/blog\/wp-content\/uploads\/2023\/04\/How-Much-Transfer-Between-Skills2.jpg 1600w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<p>Here, a few things seem pertinent:<\/p>\n<ul class=\"wp-block-list\">\n<li><strong>Expert-novice differences.<\/strong> Experts appear to represent ideas at a <a href=\"https:\/\/www.researchgate.net\/publication\/220480253_Categorization_and_Representation_of_Physics_Problems_by_Experts_and_Novices\">deeper level than novices<\/a>. The most likely explanation is that skills become more abstract as we encounter more examples and learn to generalize and distinguish concepts.<\/li>\n<li><strong>Automaticity effects<\/strong>. Skills tend to recede from conscious awareness with experience. There are many different proposed mechanisms for this in psychology, but a consequence seems to be that how the expert <em>thinks<\/em> they perform a skill may not fully capture what they\u2019re actually doing.<span id='easy-footnote-2-15058' class='easy-footnote-margin-adjust'><\/span><span class='easy-footnote'><a href='https:\/\/www.scotthyoung.com\/blog\/2023\/04\/18\/skill-transfer-explained\/#easy-footnote-bottom-2-15058' title='The &lt;a href=&quot;https:\/\/www.amazon.ca\/Beginning-Read-Thinking-Learning-about\/dp\/0262510766\/ref=tmm_pap_swatch_0?_encoding=UTF8&amp;amp;qid=1678392728&amp;amp;sr=8-1&quot;&gt;science on reading&lt;\/a&gt; seems relevant here: careful experimentation seems to indicate that fluent readers decode words letter-by-letter, even though we may feel like we recognize meaning holistically as we look at text.'><sup>2<\/sup><\/a><\/span><\/li>\n<li><strong>Mnemonic effects.<\/strong> Another complication is that even if there is no overlap between two skills in expert performance, there might be an overlap at an earlier stage of acquisition. Vimla Patel has explored this in <a href=\"https:\/\/www.tandfonline.com\/doi\/abs\/10.1080\/10401338909539394?journalCode=htlm20\">medical cognition<\/a>. She comments on the finding that basic science tends to be used infrequently in clinical practice. However, that doesn\u2019t mean learning basic science is useless for doctors because it forms a scaffolding for making sense of clinical knowledge, thus aiding in its acquisition.<\/li>\n<li><strong>Declarative-to-procedural transitions.<\/strong> Another characteristic progression in learning is for skills to start as <a href=\"https:\/\/en.wikipedia.org\/wiki\/Declarative_knowledge\">declarative knowledge<\/a>\u2014things we know and think about explicitly\u2014and shift to <a href=\"https:\/\/en.wikipedia.org\/wiki\/Procedural_knowledge\">procedural knowledge<\/a>\u2014actions we take automatically. This transformation implies that skills may have different patterns of transfer at different levels of mastery as their dominant mental representation changes.<\/li>\n<li><strong>Cognitive load.<\/strong> Different training activities work better for <a href=\"https:\/\/www.scotthyoung.com\/blog\/2022\/01\/04\/cognitive-load-theory\/\">different stages of skill acquisition and working memory capacity<\/a>. Studying an example, for instance, is better than solving a problem when cognitive load is high, but the opposite is true when cognitive load is low. Efficiency of practice, then, is more than just a question of overlap but also of the stage of learning. Early on, drills, practice on component skills and structured lessons are more helpful. Later on, complex, realistic practice matters more.<\/li>\n<\/ul>\n<p>On top of these psychological details, there\u2019s the issue of pedagogy. There are often multiple methods for teaching something. Those methods have varying levels of generality and can apply to a broader or narrower range of concepts. Transfer, then, also depends on how something is taught.<\/p>\n<p>My sense from reading this research is that there are a few pitfalls to avoid:<\/p>\n<ul class=\"wp-block-list\">\n<li><strong>Don\u2019t judge transfer potential by the abilities of novices.<\/strong> Novices have a more superficial, context-bound understanding. That\u2019s more indicative of their phase of skill acquisition than the ultimate potential for transfer. <\/li>\n<li><strong>Don\u2019t judge transfer on one-shot problem-solving tests.<\/strong> Problems often require many pieces of knowledge and procedures to solve correctly. Failure in the tested task could mean a complete failure of transfer, or it could mean that a person is 99% of the way there but still missing one piece. A better test is to train a person on task A, then on task B, and measure the time savings on B from the knowledge and skills acquired in A.<\/li>\n<li><strong>Don\u2019t trust experts\u2019 perceptions of how they do a task.<\/strong> Experts are <a href=\"https:\/\/www.amazon.com\/Strangers-Ourselves-Discovering-Adaptive-Unconscious\/dp\/0674013824\">bad at introspecting<\/a> their cognitive procedures. We tend to underrate knowledge we\u2019ve already acquired, seeing it as obvious. The ease of automaticity fools us into thinking the complex skills we perform are simple. This can lead to an inappropriate devaluing of \u201cbasic\u201d skills.<\/li>\n<\/ul>\n<h2 class=\"wp-block-heading\">Question Three: How are Skills Used in Real Life?<\/h2>\n<p>The final question is about the kinds of cognitive activities people engage in during work, school and daily life.<\/p>\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"512\" src=\"https:\/\/www.scotthyoung.com\/blog\/wp-content\/uploads\/2023\/04\/How-Much-Transfer-Between-Skills3-1024x512.jpg\" alt=\"\" class=\"wp-image-15070\" srcset=\"https:\/\/www.scotthyoung.com\/blog\/wp-content\/uploads\/2023\/04\/How-Much-Transfer-Between-Skills3-1024x512.jpg 1024w, https:\/\/www.scotthyoung.com\/blog\/wp-content\/uploads\/2023\/04\/How-Much-Transfer-Between-Skills3-300x150.jpg 300w, https:\/\/www.scotthyoung.com\/blog\/wp-content\/uploads\/2023\/04\/How-Much-Transfer-Between-Skills3-768x384.jpg 768w, https:\/\/www.scotthyoung.com\/blog\/wp-content\/uploads\/2023\/04\/How-Much-Transfer-Between-Skills3-1536x768.jpg 1536w, https:\/\/www.scotthyoung.com\/blog\/wp-content\/uploads\/2023\/04\/How-Much-Transfer-Between-Skills3.jpg 1600w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<p>While possibly the most relevant question of the three, it is also the hardest to answer. Few studies have looked systematically at the kinds of cognitive skills people regularly employ at work and at home.<\/p>\n<p>Critics allege that much of what we learn in school has little real-world application.<\/p>\n<p>John Anderson <a href=\"https:\/\/www.amazon.ca\/Learning-Memory-Integrated-John-Anderson\/dp\/0471249254\">reports<\/a> that employers either want very basic skills (which the educational system should already be teaching) or highly specific skills that no universal curriculum could aspire to. Similarly, Peter Cappelli <a href=\"https:\/\/www.amazon.com\/Why-Good-People-Cant-Jobs\/dp\/B00FJUFFD8\/?_encoding=UTF8&amp;pd_rd_w=Smadj&amp;content-id=amzn1.sym.22f5776b-4878-4918-9222-7bb79ff649f4&amp;pf_rd_p=22f5776b-4878-4918-9222-7bb79ff649f4&amp;pf_rd_r=138-5005353-2745032&amp;pd_rd_wg=vgzAZ&amp;pd_rd_r=36883576-42ee-403e-89ee-0ccca61e0046&amp;ref_=aufs_ap_sc_dsk\">argues<\/a> that surveys show employers tend not to highly value academic skills.<\/p>\n<p>Jean Lave <a href=\"https:\/\/www.amazon.ca\/Cognition-Practice-Mathematics-Culture-Everyday\/dp\/0521357349\/ref=sr_1_2?crid=2UHF1GP7YERE1&amp;keywords=jean+lave+cognition+in+practice&amp;qid=1681499209&amp;sprefix=jean+lave+cognition+in+practic%2Caps%2C142&amp;sr=8-2\">found<\/a> that the mathematics taught in school is rarely what people use in their daily routines.<\/p>\n<p>Bryan Caplan <a href=\"https:\/\/www.amazon.ca\/Case-against-Education-System-Waste\/dp\/0691174652\">argues<\/a> that much of education is signaling\u2014showing others we have smarts, conformity and work-ethic\u2014rather than cultivating those abilities. From this perspective, the real purpose of schools is to sort people, not to teach useful skills. School knowledge doesn\u2019t apply to real life, Caplan argues, because that\u2019s not the function it serves in society.<\/p>\n<p>Supporters of education argue that just because most skills aren\u2019t used doesn\u2019t mean they\u2019re useless. We may become specialists of one sort or another, but unless we assign everyone a career at birth, we want to maintain maximum flexibility until our adult years. A side-effect of this desire to maintain flexibility is that we end up learning a lot that we don&#8217;t ever end up using, or that is insufficiently concrete to apply in practice without further training.<\/p>\n<p>Similarly, education proponents <a href=\"https:\/\/www.amazon.ca\/Mindware-Tools-for-Smart-Thinking\/dp\/B0719GQ4GZ\/ref=sr_1_1?hvadid=284313338521&amp;hvdev=c&amp;hvlocphy=9001556&amp;hvnetw=g&amp;hvqmt=e&amp;hvrand=15299944356742459999&amp;hvtargid=kwd-314760458336&amp;hydadcr=14950_9480932&amp;keywords=mindware+nisbett&amp;qid=1681499263&amp;sr=8-1\">point out<\/a> that just because a skill isn\u2019t used doesn\u2019t mean it can\u2019t be. Statistics is a powerful tool for reasoning about many important issues. The fact that people are statistically naive shows we should be teaching them more, not declaring it impotent!<\/p>\n<p>Whether we apply a skill in a new context depends on the effort it requires. Practice can lower the effort of applying a skill in real life and create more situations where it is convenient to use. Imagine rewinding time to before widespread literacy; it would be perverse to argue that reading isn\u2019t useful because most people don\u2019t read.<\/p>\n<p>My perspective is that, while many academic subjects aren\u2019t used, it\u2019s difficult to appreciate a subject until you learn it. Given that we generally cannot \u201cinfer\u201d a domain of knowledge simply by encountering problems that apply it, this argument favors accumulating more knowledge than you think you\u2019ll need.<\/p>\n<h2 class=\"wp-block-heading\">Side Note: Transfer of Effort, Motivation and \u201cNoncognitive\u201d Skills<\/h2>\n<p>Thus far I\u2019ve been looking at transfer through a cognitive lens. A somewhat separate issue is the transfer of things like the ability to focus and study for long periods of time, the ability to resist temptations, or the motivation to want to learn.<\/p>\n<p>Many of the same arguments used above apply to noncognitive skills as well. There\u2019s unlikely to be something like a general faculty you can improve with bulk training efforts for motivation, persistence or focus.<\/p>\n<p>That said, the arguments about transfer here are somewhat different because these are not complex skills (in the information processing sense of \u201ccomplex\u201d). Sitting at your desk and focusing for eight hours may be difficult, but it\u2019s not <em>computationally<\/em> demanding. <\/p>\n<p>Thus while I think it\u2019s ridiculous to imagine improving your memory by memorizing Latin verbs, it\u2019s not ridiculous to imagine improving your ability to focus by regularly sitting down to focus. Believing that cognitive skills are highly specific, and should show limited transfer, is not logically incompatible with a more general transfer of effort or persistence.<\/p>\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"512\" src=\"https:\/\/www.scotthyoung.com\/blog\/wp-content\/uploads\/2023\/04\/How-Much-Transfer-Between-Skills4-1024x512.jpg\" alt=\"\" class=\"wp-image-15071\" srcset=\"https:\/\/www.scotthyoung.com\/blog\/wp-content\/uploads\/2023\/04\/How-Much-Transfer-Between-Skills4-1024x512.jpg 1024w, https:\/\/www.scotthyoung.com\/blog\/wp-content\/uploads\/2023\/04\/How-Much-Transfer-Between-Skills4-300x150.jpg 300w, https:\/\/www.scotthyoung.com\/blog\/wp-content\/uploads\/2023\/04\/How-Much-Transfer-Between-Skills4-768x384.jpg 768w, https:\/\/www.scotthyoung.com\/blog\/wp-content\/uploads\/2023\/04\/How-Much-Transfer-Between-Skills4-1536x768.jpg 1536w, https:\/\/www.scotthyoung.com\/blog\/wp-content\/uploads\/2023\/04\/How-Much-Transfer-Between-Skills4.jpg 1600w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<p>I might write a fuller summary of my views later, but I want to clarify that while \u201cspeaking French\u201d and \u201cbeing able to focus\u201d are both discussed as skills, they have a different locus of difficulty. French is hard because there are lots of words, grammar and mental processes you need to perform it.
