If you decide to learn a language, one of the most important decisions you can make is choosing the right learning strategy. This choice will either allow you to progress fast or break you mentally like a twig. It's the difference between moving forward in a Ferrari versus using your tears as a lubricant while you crawl.

In the past, I have written a lot about what factors affect vocabulary acquisition and how to tell decent or good language methods from the bad ones. However, people often mistakenly interpret their initial results with a given method as a sign that it truly works. It's like getting into an expensive SPA and seeing crap-stained walls with the graffiti "Steve was here". Disappointing, that is.

When it comes to increasing your passive vocabulary, it almost doesn't matter which strategy you choose - reading, learning flashcards, humming songs. They will all work, more or less, equally well.

However, testing whether your method of activating vocabulary is effective is way trickier. Let me show you how you can verify it and what you should be wary of.

How Can I Tell That I Really Know Words Actively

2 types of recall

Considering that we're interested in testing whether you know your words actively, we must test your recall. In other words, we must know whether you can retrieve a word in your target language when you signal it to your brain during a conversation.

The first thing you need to know is that there are two types of recall.

Free recall

Free recall is the process in which a person is given a list of items to remember and then is tested by being asked to recall them in any order. There is no natural context which might trigger the words you know.

Free recall often displays evidence of primacy and recency effects. Simply put, if you have just finished your learning session and you can feel dozens of words thrumming in your head, you have just experienced recency effect. The information that you are exposed to at the of your studies is easier to recall. The same goes for the information you have contact with at the beginning of your session - that's the primacy effect.

Cued Recall

Cued recall is when a person is given a list of items to remember and is then tested with cues to remember the material.

The word "cues", or contextual triggers, as I like to call them, are key concepts here.

Why Free Recall Is a Bad Measure of Your Ability to Remember

Anytime somebody switches to a new learning method, especially if their baseline was good, old-fashioned cramming, they might experience improved initial recall. Does it mean that they remember more long-term? Absolutely not, although but a few people are aware of this.

The word "initial" in this case is just a synonym for short-term learning. It gives you an illusion that knowledge has been acquired. However, once this illusion is confronted by precise measurements, it turns out that not much has been retained.

Free Recall and the Illusion of Knowledge

It's also a very common theme regarding many passive learning strategies like reading, restudying, highlighting, etc. The science knows beyond the shadow of the doubt that they are useless, but students still prefer them over battle-tested strategies like spaced repetition.

The above echoes something I have been saying for years - if you simply assume that a learning strategy is effective just because you feel some initial benefits, it doesn't make it true. Unless you test it, it's better to suspend your opinion for some time.

Example: intensive reading and initial learning

A good example of this phenomenon is intensive reading. It can certainly be a good and effective learning strategy for advances learners, but it's absolutely terrible for beginners.

These "immediate vocabulary gains" are nothing more than a sign of initial learning. It shouldn't however be confused with long-term retention or, as I call it, the real learning. Sadly, most authors of language-related research don't seem to understand it.

What Is the Measure of Real Learning?

Once again, you can take almost any learning method and you will get (relatively) promising results short-term. 

However, only transfer tasks, such as using words in a conversation are a good measure of true learning (Mayer, 2009).

Stress - a Crucial Factor That Needs to Be Taken Into Consideration

Every good language learning methodology can be encapsulated by the Marines' adage:

You should always to train for reality in a manner that mimics the unpredictability and conditions of real life. Anything else than that is simply a filler. Unfortunately, regardless of how good your learning method is, it's almost impossible to incorporate a crucial factor for your ability to retrieve and know your words actively - stress.

Even if you can confidently reproduce words from ANKI at the comfort of your home, it doesn't mean that you will be able to use them in a conversation. Learning in such conditions is always, to some degree, detached from reality. You have time to contemplate the right answer, and everything feels pretty snugly and comfy.

Compare it with a typical conversation where:

How Stress Affects Your Brain

That means that it doesn't matter how confidently you can recall words in the comfort of your home. If your vocabulary is not consolidated well enough, instead of producing fluent speech, it might turn out that you sound like a goat in the middle of the breeding period.

However, there is an easy way to fix it.

Want to Know Words Actively? Overlearn!

Items that are difficult to learn should be overlearned to ensure long term retention (Hulstijn, 2001).

You get the gist. Children are a wonderful example of overlearning in action. For example, not that long time ago, my son got so excited by getting a piece of cheese that he repeated this word 53 times (yes, I counted).

53 freaking times. It made me feel lazy and question the effort I put into learning!

How Can I Tell That I Really Know Words Actively - Summary

Most language learning methodologies are plagued by one fatal flaw. They make you believe that being able to reproduce a word in the comfort of your home is equivalent to really knowing it.

Unfortunately, the truth is more complicated. First of all, the ultimate test of your active vocabulary is always a conversation. If you can comfortably recall your newly acquired vocabulary, then you can be relatively confident that your approach works. I say "relatively" because unless you test a given method, you can't be sure that it's precisely what makes you recall words effectively. Most of the time, it's the results of combining a couple of learning strategies. 

What's more, if your learning method doesn't involve context and active transfer of your vocabulary between contexts, you can rest assured that it sucks.

Last but not least, if your learning strategy does involve context and active information transfer them, you should put more effort into overlearning those problematic words.

Keep in mind that this is one of those situations where individual differences kick in. Some people are more immune to stress than others. As a consequence, the degree to which you will have to overlearn words will often depend on your genetics and environmental conditioning.
