Information Processing, Human Error and the Learning Process — Page 168, Lesson 268

I want to walk you through the topic of information retention and the factors that influence learning. Let's start with retention of information — how we can make what we learn stick in memory for longer. One of the most practical tools pilots use is mnemonics. These are memory aids where a word or phrase stands for a checklist of items. In aviation, you'll see examples like "HASELL", "FEFL", or "FREDA" — each letter triggers recall of a specific check item. So when you say "HASELL" to yourself before a manoeuvre, your brain unpacks the whole sequence. Another method is memory training. The book lists several common techniques here. First, word/phrase or object association — you link a new fact to something familiar. Then chunking, which means grouping individual pieces of information into larger, meaningful units — for example, remembering a radio frequency as three two-digit chunks instead of six separate digits. Repetition is simply going over the material again and again. Revision means returning to it periodically after the initial learning. And research — actively looking into a topic deepens your understanding and retention. Now let's talk about motivation. The book makes a key distinction: it is possible to learn without motivation, but attention is essential — you cannot learn something you don't pay attention to. However, the learning process is vastly improved with motivation, and high performance rarely comes without it. The book also tells us that motivation is always enhanced by reinforcing successful endeavours — when you succeed at something, that success itself fuels your drive to keep going. This topic is discussed in more detail in Chapter 9 on Behaviour. Next, experience. We all have the ability to learn from our own experiences and mistakes, and from those of others. Here's an interesting finding from the book: although age severely affects pilots' learning abilities and slows both mental and physical reactions, their actual performance decreases by a very small amount, if at all, with advancing years. Studies have concluded that these deficiencies are compensated for by experience. So the knowledge and judgement built up over time can offset the natural slowing that comes with age. Finally, let's look at mental schema. A mental schema is a mental representation of a category of objects, events, or people. The book gives a great example: most Englishmen have a mental schema for football. Simply hearing the word "football" activates whole clusters of information in long-term memory — the rules of the game, images of players, goal posts, balls, vests, stadiums, green playing fields, winter days, and even hotdogs. Your brain fills in all that context automatically. But schemas can also lead us astray. The book mentions a study with graduate students in an office — their mental schema of what a graduate student's office should look like led them to "remember" things that weren't actually there. So schemas help us process information efficiently, but they can also introduce errors when our expectations override what we actually saw. That covers retention, motivation, experience, and mental schemas.
