Can We Predict Which People Will Be Better At Learning Foreign Languages?
One common gripe we probably have when we observe that friend who can speak effortlessly in a dozen different tongues may be something along the lines of: “Why is he or she so good at learning languages – it’s not fair!” Well, now it appears that perhaps there is indeed some hidden advantage this friend has over ourselves: How our brain is “wired” affects how we pick up a new language.
A recent study has shown for the first time that people who have difficulty in learning a new language could have brains that are wired in a way that reduces their ability to acquire the necessary linguistic skills. In particular, this means that the intrinsic differences in how different brain regions communicate with each other makes it significantly easier for some adults to learn a second language as compared to others.
Scientists now are able to use brain scans to effectively determine how good a person’s language acquisition abilities are. It turns out that this is directly linked to the ability of the communication of the brain’s language centres when we are in a state of rest. The reason for this is that a large part of our learning processes actually occurs when we are resting – indeed, it is not surprising that sleep is of critical importance to both our learning and health.
Now, scientists have discovered that the learning of language is considerably easier if there is a higher degree of communication between two regions of the brain, more specifically when the left anterior operculum interacts more with the left superior temporal gyrus (an integral part of the language network in our brains). This has strong implications for predicting the ease (or lack thereof) at which one can learn a new language.
The study described herein involved a total of 15 English-speaking adults who were about to enlist in a course to learn French that spanned 12 weeks of intensive training. Prior to and after the course, the brains of these participants were scanned and their language abilities were tested. It was shown that those who had improved connections between the aforementioned brain regions demonstrated a much bigger degree of improvement in the administered speaking test, highlighting the important role brain wiring plays in language acquisition.
Brain rhythm patterns and the ability to learn a foreign language
In addition to the inherent “wiring” of the brain, it has also been shown recently in a separate study that the brain rhythm patterns of an adult can be another good predictor of how well he or she can learn a new language – and this measurement of brain activity during a resting state only takes a mere five minutes. In this study, scientists show that the brain’s resting state rhythms could be analyzed for characteristics that account for 60% of the variability influencing an adult’s ability to acquire a second language. The participants in this study were 19 adult volunteers with ages ranging from 18 to 31 years without any prior experience with learning French. With their eyes closed, the volunteers sat for five minutes. During this time period, they were equipped with an EEG (electroencephalogram) headset, which served to provide measurements of brain activity patterns.
For the length of the study, which took place over a total of eight weeks, the volunteers went to the lab two times a week to take part in French lessons with each lasting 30 minutes. These language-training lessons were administered via a computer utilizing an immersive virtual reality program funded by the United States Office of Naval Research. The program is termed the Operational Language and Cultural Training System (OLCTS), and seeks to enable members of the military to gain rudimentary proficiency in a new language with only 20 training hours. Notably, the program is self-paced and provides a sequence of stories and scenes to facilitate learning. A component to recognize voices is also incorporated to allow for easy verification of pronunciation.
Additionally, the scientists included quizzes at various points in the course that required a minimum score before allowing participants to move on to the subsequent lesson. This ensured that the users were attentive when going through the lessons and also doubled as an indicator of the speed at which each user went through the designated syllabus.
After the conclusion of this training regimen, the volunteers took a test that assessed their proficiency in the new language (the coverage of the test was based on the number of lessons completed). Even though the fastest participant learned twice as quickly as the slower ones, the latter learned just as well in terms of their language proficiency. From the EEG headsets, the recordings showed that specific brain activity patterns that were linked to language-related processes had the highest correlation to the volunteers’ ability to pick up a new language, indicating that these patterns could plausibly confer some inherent benefits for people looking to learn a second language.
Are “brain advantages” the only determinants of language learning?
In the light of the findings described in this article, it is pertinent to note that the brain’s wiring does not unequivocally predetermine a person’s ability to learn a new language, given that there are many other innate as well as environmental factors involved, such as the motivation of the individual. In a similar train of thought, this does not mean that people without the “advantageous” brain pattern should not try learning a second language as such a pattern only accounts for 60% of the variability in language acquisition. This means that other factors play important roles in the learning process and should be taken into account as well.
The brain’s plasticity means that different learning stimuli and experiences can shape how it develops. To this end, these studies provide key insights into how the learning of a new language can be influenced in individual-specific differences. In this regard, it would logically follow that the long-term goal would be to eventually develop more targeted approaches for individuals to facilitate their language acquisition.
Moreover, brain activity in the resting state can be modified using a type of training dubbed neurofeedback training, for which work is ongoing currently. This program regimen allows users to strengthen brain patterns related to enhanced cognition in order to improve their performance in language learning. Hopefully, this can subsequently be extended to improving learning abilities in general in the future – an exciting concept with boundless applications.

Making Decisions on a “Hangry” Impulse
“Hangry” is slang for that feeling of anger you may get when you’re hungry. It’s very common, in my experience… My friendly advice: don’t make any important decisions when you’re hungry. Why? Because you’re more likely to act on an impulse. And this is not just a personal conclusion: this was actually the main finding of a study carried out at The Sahlgrenska Academy of the University of Gothenburg in Sweden, and recently published at Neuropsychopharmacology.
Impulsivity is a form of impaired decision-making wherein decisions are made with a lack of ability to plan for the future. Broadly speaking, impulsivity includes two components: impulsive actions and impulsive choices. These impulsive behaviors are characteristic of many psychiatric and behavioral disorders, such as gambling, substance abuse, eating disorders, for example. Research on the neurobiological mechanisms of impulsivity has established a role for some major neurotransmitters, including dopamine and serotonin.
But where does hunger fit into this? Apparently, the gut has a word to say when it comes to impulsivity. Both dopamine and serotonin are known to be modulated by a hormone that is produced by the stomach – ghrelin. Ghrelin is an appetite stimulant, which means that its levels increase during the initial period of food restriction, and this increase acts as a trigger for hunger, thereby leading to food intake. Ghrelin also increases the rewarding feeling of food through the action of dopamine and opioids. Food reward is in turn known to be positively correlated with impulsivity. And ghrelin seems to influence dopamine release in areas of the brain associated with increased impulsivity in humans. Ghrelin can also increase the levels of dopamine and the activity of dopaminergic neurons in areas of the brain associated with motor control and is thereby potentially associated with motor impulsivity.
Take together, this suggests that ghrelin may theoretically act as a neurobiological regulator of impulsivity. And that was precisely what the study mentioned above aimed to determine. The authors assessed the role of ghrelin on impulsive behavior, namely on the ability to inhibit or restrain a behavioral response and to delay gratification.
Their work showed that ghrelin increases impulsivity in rats that had to perform different tasks of impulsive responding, being able to affect both impulsive actions and impulsive choices. When a large food reward could be obtained without delay, ghrelin administration predisposed the animals to selecting that larger food reward; nothing surprising here – more food sounds like an obvious choice. But when obtaining a larger reward required waiting, a smaller but immediate reward became preferred. This revealed that ghrelin administration led to an inability to delay gratification, which is a manifestation of impulsive behavior.
Ghrelin’s association with dopamine release was also studied and it was shown that ghrelin administration led to an increase in the levels of dopamine in areas of the brain associated with impulsive behavior. Ghrelin treatment caused a reduction in the expression of an enzyme responsible for dopamine degradation, consequently leading to an accumulation of the neurotransmitter in that area. Reduced activity of that enzyme (Catecol O-Metiltransferase – COMT) is actually associated with attention-deficit/hyperactivity disorder and obsessive-compulsive disorder in humans, two conditions in which impulsive behaviors are paramount. This sustained the hypothesis that ghrelin’s effect on impulsivity occurs, at least partially, through the action of dopamine.
Besides explaining why we become so impulsive when we need food, this study also establishes another link between the gut and the brain: it shows how a gut-produced hormone regulates neurobiological mechanisms of impulsive behavior.
So, remember: whenever you get “hangry”, you can blame it on ghrelin. I sure will!
