Non-Conscious Aspects Of Learning And Performance

Being on autopilot has a lot of implications for learning and performance. Recently, Guy Wallace (@guywwallace on Twitter) posted about experts having difficulties figuring out what people must learn to perform a task. But experts often unintentionally leave things out. Their performance is highly automated so they no longer have conscious access to exactly what they are doing.

Automated and non-conscious prior knowledge is stored in long-term memory. An expert’s deep prior knowledge makes them far more capable of solving difficult problems in their area of expertise. But because it’s automated and non-conscious, they’re often unaware of exactly what they are doing.

Guy pointed me to Richard Clark’s article, The Impact of Non-Conscious Knowledge on Educational Technology Research and Design. And this article turned out to be a goldmine of important information. Experts, research finds, tend to be conscious of the physical actions they take, as well as the knowledge they use. But they are much more unaware of the mental activities used to perform tasks and solve problems.

No! No. Background. Music.

<-- I started building a series of explainer videos this week on the most critical concepts in my Make It Learnable series of books. The first one is on learnability and readability in instructional materials and how they impact learning outcomes. I want to help people understand the importance of evidence-based concepts in building good instruction.

I tried out a number of explainer video applications (or applications that could be used for this purpose) and too many had fatal flaws. I wanted to use Camtasia as I have the application and love its ease of use. But I couldn't get the audio to work right. After two days of trying and working through help files (noting that others had similar problems), I gave up. But I'd like to use it again if I can figure out how to get the audio working.

I looked at other tools and tried them, but most had even larger fatal flaws. The one that worked immediately was Powtoon. There is a serious flaw: No ability to input a transcript for those who cannot hear the video. I'm looking for a workaround. (Let me know if you have one.)

When I bought Powtoon, I had to decide which upgrade to purchase. The higher versions had more objects, backgrounds, and background music. But background music should typically NOT be used in instructional video. The reason is easy to understand and quite clear. Added music makes attending to the important messages on the screen more difficult. In other words, it adds extraneous (harmful) cognitive load.

When people are learning, their mind has to select the important messages from what is shown and mix them with what they know to make meaning. This is. Hard. Work. Adding extraneous (extra) messages, images, and music makes this even harder.  We absolutely should not do anything to make understanding harder.

You shouldn't use background music unless your lesson is about background music. If you want to understand cognitive load better, consider reading Write and Organize for Deeper Learning or Practice and Feedback for Deeper Learning.
