In this blog, we have presented several benefits of being bilingual. We have also shown that bilinguals’ brains behave somewhat differently (in a positive way) when compared to monolinguals’. In addition, in a fairly new experiment carried out by Jubin Abutalebi of the Vita-Salute San Raffaele University, the relationship between being bilingual and a slower development of Alzheimer’s disease (AD) has been studied.
They found that bilinguals develop AD slower than monolinguals, and the provide a possible explanation for that. First of all, in previous studies it has been shown that bilinguals with AD have more atrophy in the brain than monolinguals with the same disease. However, it seems that AD takes more time to develop in bilinguals’ brain because they have “better connectivity between intact neurons”. Abutalebi, however, mentions that “only those who really use the two languages are protected”. In any case, the findings in this study are undoubtedly crucial for future investigations.

New benefits for bilinguals! A new study reveals that being bilingual can affect your brain by changing its structure. According to Judith F. Kroll, bilinguals’ ability to retain two languages and to alternate between them has an effect on the reshaping of the brain’s network.
In a recent study, they analyzed 60 monolingual and 60 bilingual infants whose ages ranged between four-month old, eight-month old, and one-year old babies. They noticed that when someone was speaking, infants exposed to Spanish and Catalan looked at speaker’s mouth instead of their eyes. Infants that were only exposed to Spanish, on the other hand, looked at the mouth of speakers only when they were talking their native tongue.This study suggests that being bilingual improves their cognitive abilities because “babies who are listening to two languages [growing up] become attuned to those two languages right away. It’s not confusing them or messing them up developmentally—the opposite is true”.

In our last posts we have shown the advantages of being bilingual in children. However, what happens to bilinguals’ brain when they age? Several studies have claimed that bilingualism increases resilience to losing brain capacity. Recently, Perani and her colleagues carried out an experiment in which they compared patients with Alzheimer’s, both monolingual and bilingual.
The results revealed that bilinguals were better at ‘verbal short-term memory and long-term memory’. In addition, monolinguals had more advanced signs of disease. On the other hand, bilinguals were around five years older. In any case, other experts like Duñabeitia claim that more longitudinal studies are needed in order to get clearer conclusions.

In addition to the several advantages of bilingualism mentioned in this blog, a recent study has found that bilinguals have better attention and focus.
Researchers from the University of Birmingham recruited 99 participants from which 48 were English-Chinese bilinguals while the other 51 were English monolingual speakers. Participants carried out 3 different tasks: the Simon task, the Spatial Stroop task and the Flanker task. These tasks consisted on indicating the direction or the color of arrows and squares while ignoring extra information. Both groups scored similarly. However, the monolingual speakers had slower responses than bilinguals.
Researchers concluded that bilinguals are better at focusing because the response time of bilinguals was faster than monolinguals’. According to the researchers, this could be due to the fact that “the lifetime task of switching between languages appears to enhance the ability to maintain attention.”

Two recent studies have concluded that multilingual exposure improves not only a child’s cognitive skills, but also their social abilities.
The first study, conducted by Dr. Katherine Kinzler’s lab, found that multilingual children were better at communication than children who only spoke one language. In their experiment, multilingual children did not only pay attention to what the adults were saying, but also to the context and the perspective of the interlocutor. Interestingly, they also found that “being raised in an environment in which multiple languages are spoken, rather than being bilingual per se, is the driving factor”.
In the second experiment, which was a follow-up study, they examined the effects of multilingual exposure on children that could hardly speak (14- to 16-month-old babies). In this follow up, led by Professor Liberman, they concluded that children raised in multilingual environments were more aware of the importance of the adult’s perspective for communication, even when that exposure to the second language was minimal.
With these results in hand, these researchers have argued that “Multilingual exposure, it seems, facilitates the basic skills of interpersonal understanding”.
