Are we really “fit or not” to learn foreign languages? And if so, why?

Learning foreign languages is often seen as a natural talent: some people seem to make rapid progress in grammar and vocabulary, while others find it difficult and discouraging. But is it a question of “gift” or innate predisposition? In reality, a variety of factors – genetic, neurological, environmental and psychological – influence this ability. Let’s explore these elements together, along with case studies and practical examples to better understand what shapes our ability to learn a new language.

1. Natural predispositions: what science says

Genetics plays a role in language learning, but it’s only one factor among many. Studies on identical twins have shown that certain genetic variants can influence language skills. For example, research by behavioral psychologist Robert Plomin suggests that there is a correlation between genetic predispositions and sensitivity to linguistic stimuli.

Noam Chomsky, the famous linguist, proposed the idea of a language acquisition device (LAD), a kind of innate “universal grammar” that enables children to understand the basic rules of any language. This ability is particularly marked in the first years of life, which explains why bilingual children can assimilate two languages simultaneously with remarkable ease.

Here’s a concrete example: thanks to their cerebral plasticity, bilingual children often master several languages with impressive fluency, illustrating the brain’s innate ability to absorb complex structures.

2. Environmental factors: the role of context

Context plays a crucial role in language learning, especially during childhood. A 2018 MIT study reveals that the ability to learn a language gradually declines after the age of 18, although early exposure to a foreign language significantly increases the chances of assimilating it like a native speaker.

Practical example: Children from immigrant families often master the language of the host country faster and more effectively than their parents, who began learning it as adults.

Furthermore, educational approaches such as CLIL (Content and Language Integrated Learning) demonstrate that combining language learning with other disciplines, such as science, significantly improves language skills. In Finland, for example, students taking courses in English achieve better results than those learning in a single language.


3. Motivation and psychology: powerful driving forces

Motivation is at the heart of language learning. According to psychologist Robert Gardner, there are two main types of motivation:

  • Integrative motivation: the desire to immerse oneself in a culture.
  • Instrumental motivation: the need to learn a language for professional or academic reasons.

A striking example is that of refugees, who, driven by the urgency of integration, acquire new languages rapidly despite sometimes difficult conditions.

But anxiety can put the brakes on learning. Research from Oxford University shows that the fear of making mistakes is a major obstacle. This is why communicative teaching methods, such as the Berlitz Method, emphasize interactive simulations that reduce pressure and increase self-confidence.


4. Age and brain plasticity: assets at every stage of life

Although children have exceptional brain plasticity that facilitates learning, adults too can excel with the right methods.

Inspiring example: Steve Kaufmann, a former Canadian diplomat, learned more than 20 languages after his 50th birthday. He attributes his success to constant practice, cultural exposure and the use of digital tools such as learning apps.

In contrast, the case of Genie Wiley, an American child raised in isolation until the age of 13, illustrates the limits of learning after a critical period. Despite considerable effort, Genie was never able to fully master a language, highlighting the importance of early exposure.
