Even though much has been written about how to use passive learning, i.e. reading and listening, in language learning, many language learners still puzzle over the following question, "How can I leverage it in order to speed up my learning progress?"

This question is extremely important because the way you combine passive and active learning is actually the key to learning a language fluently.

The purpose of passive learning - it helps to memorize

One of the most frequent claims in the language learning community is that passive learning (i.e. reading and listening) is very helpful with memorizing new vocabulary.

Is it true?

The answer is, surprisingly, yes and no. It simply depends on your current language level.

When is Passive learning useful for memorization?

If we take a look at the scientific literature, we can learn that there are two important milestones concerning your ability to learn from the context:

When is passive learning useful for memorization?

1) 3000 words (B1/B2 level)

3000 words allow you to understand about 95% of most ordinary texts (Hazenberg and Hulstijn, 1996). It seems like a lot.

Sure, on this level, you will be able to hold a decent conversation. You will also be able to get the general ideas and concepts of most of the articles.

This milestone is also important because it's so-called the minimal threshold for passive learning. It means that reading and listening start making sense only at this level (read more about how many words you need to know for every language level).

2) 5000 words (B2, B2/C1 level)

5000 words allow you to understand about 98% of most ordinary texts (Nation (1990) and Laufer (1997)).

Such a vocabulary size warrants also accurate contextual guessing  (Coady et al., 1993; Hirsh & Nation, 1992; Laufer, 1997).

For exactly that reason this milestone is called the optimal threshold for passive learning.

As a sidenote, my personal experience is this - even 5000 words are not enough to start memorizing words. You should aim for at least 8000 in order to do it efficiently.

The conclusion from the above is simple.

The purpose of passive learning - it compliments active learning

In order to understand well the function of passive learning in the learning process, we need to start at the source - the simple model of memorization.

The simple model of memorization:

This sexy model tells us that in order to acquire knowledge quickly and efficiently, you need to encode information. In other words, you need to manipulate the information in a meaningful way.

Is the element of encoding present in passive learning (i.e. reading or listening)?

Of course not!

That's the reason why active learning is much better suited for learning material fast.

However, the problem with active learning is that it's tiring as hell even though it doesn't take a lot of time. At the end of your learning session, you should feel as if you have been mauled and teabagged by a bear at the same time.

It's not pretty.

Ok, so you already know that active learning is:

What it tells us is that you can do learn actively only for the limited period of time before you run out of steam. In other words, active learning is not sustainable long-term.

What happens then? Do you just call it a day? Nope. You switch to passive learning.

If you stick to this formula, you are guaranteed to learn relatively fast.

Of course, this isn't the only benefit of reading and listening.

The purpose of passive learning - it primes your memory

What is priming?

Before I move on, let's clarify what priming is.

Now that you know what priming is, it's time to take a look how it affects our memory.

How does priming affect our memory?

There is one main effect of priming on our memory.

We process frequent collocations faster than infrequent ones.

How is it possible?

Because our memories are organized into something called "schemas".

"Schema'' is used as a general term to cover all kinds of general knowledge. More closely specified versions of schemas are called scripts, which consist of general knowledge about particular kinds of events, or frames, which consist of knowledge about the properties of particular objects or locations.

Fun fact about priming

Priming can take many different forms and shapes. One which you might find really interesting is syntactic priming.

Yes. The more time you spend with somebody, the more likely it is that you will understand this person's idiolect (or that you will adapt it).

Idiolect is an individual's distinctive and unique use of language, including speech.

As you can see, priming is a truly powerful weapon as it relates to concepts which are not in their direct proximity.

What it means practically is that your brain will still be able to understand a collocation even if you interject an extra thought into a sentence.

Here is an example of this phenomenon: "I wanted to cook a dinner, so I started to cut an onion, you know, with, like, a really sharp knife".

How long can priming last?

Findings suggest that auditory word-priming effects have a long-term memory component and are long-lasting (Trofimovich 2005: 481).

What does it mean that they are long-lasting?

It's speculated that these effects can last months or even years.

Practical consequences of priming

Speaking slower

Speaking fluently is a really tricky thing.

Why?

Because you have to combine two things.  First of all, you need to actively memorize new words, ideally, by creating a new context for them.

That will see the said words in your memory. The problem is that, as I have said before, unless you have a lot of contexts, you won't be able to recall them fast.

Is the solution creating a lot of sentences for a given word?

Sure, it will work, but it's too much consuming. However, if you start learning passively, you will be exposed to dozens of different contexts for almost every possible word you know.

From then on, whenever you run into a situation which fits your script, your primed words will be right there at the top of your tongue.

If you have ever struggled with fluent speaking, I can guarantee you that you're missing one of these puzzle pieces.

Problems with comprehension

Keep in mind that the richer your words of associations for a given word, the easier it is to understand it.

Reading and, especially, listening are amazing learning tools which will expand this network relatively effortlessly.

Final words

Passive learning is certainly a misunderstood language learning tool. Even though it's often touted as a great tool for memorization, it's actually pretty ineffective in this department unless you are already an advanced learner. Its real power lies in creating an extensive network of contexts and connections which allow you to both recall and understand words much faster.
