Bilingualism has been commonly used in scientific and common nomenclature to refer to the knowledge and/or use of two languages, though the specifics of the definition have been widely debated (e.g. Altarriba & Heredia, 2008; De Groot & Kroll, 1997; Grosjean, 2010). In fact, one half (Grosjean, 2010) to two-thirds (Walraff, 2000) of all people in the world have been estimated to routinely use more than one language in everyday communicative contexts. Given this global linguistic profile, it has been suggested that an increasing number of people with communication difficulties post-brain injury are likely to be bilingual (Ansaldo, Marchotte, Scherer, & Raboyeau, 2008; Centeno, 2009). Bilingual aphasia refers to difficulties in …show more content…
The cognitive control of language selection became particularly relevant as scientists began to explore the neurolinguistic underpinnings of language recovery in individuals with bilingual aphasia.
Individuals with bilingual aphasia regaining language abilities post-brain injury have been observed to exhibit several different patterns of recovery. Bilingual persons with aphasia (PWA) often demonstrate impairments in both their languages, which may or may not be consistent with their pre-stroke language dominance (Fabbro, 1999, 2000, 2001; Paradis, 1995, 1998, 2001). Paradis (2001) reviewed published reports of bilingual PWA and found that a majority of them (61%) demonstrated equal recovery of language abilities in both languages, analogous to their proficiency prior to brain injury (parallel recovery). In the other participants, language recovery post-stroke was marked by better recovery in one language compared to the other (differential recovery; 18%), inappropriate mixing of the two languages (blended recovery; 9%), recovery of one language only (selective recovery; 7%) or recovery of one language after another (successive recovery; 5%). Fabbro (2001) evaluated the recovery profiles of 20 right-handed, high-proficiency bilingual PWA and also found a predominance of parallel recovery (65%) followed by differential recovery (35%). But despite the higher prevalence of parallel recovery, relatively
Having the ability to speak more than one language influences one’ life deeply. Speaking two or more languages can affect someone from being infants to old age. Bhattacharjee continues with, “The bilingual experience appears to influence the brain from infancy to old age (and there

Moreover, studies on bilingual language processing have shown that when bilingual speakers, listen to, read, or produce sentences, linguistic competency in both languages is activated, even when the speaker uses one language (Kroll, J. F., Bobb, S. C., & Hoshino, N. (2014). This cross-language activation can be detected in both beginners and highly skilled bilinguals and can be found at various levels of language processing system, such as lexicon, phonology, and grammar. In particular, cognitive research on bilingualism suggests that a bilingual speaker’s second language, which is not used in word recognition and language production, is being suppressed and the language that tends to be self-controlled is the native language of the speaker, not the second foreign language, implying that the native language is indeed compromised to accommodate the second language. The control system used to cognitively prohibit and switch languages is a control system commonly used for
Aphasia is a communication disorder that affects many adults and families. Aphasia occurs as a result of damage to the language-specific areas of the brain (ASHA, 2014). Individuals with aphasia may experience difficulties with oral language, receptive language, memory, attention writing, and reading. There are a myriad of approaches designed for the treatment of aphasia. Two treatment approaches, Promoting Aphasics Communicative Effectiveness (P.A.C.E.) and Constraint Induced Language Therapy (C.I.L.T.), and their efficacy in regard to available evidence will be discussed below.
In a study of bilingual adults, non-verbal executive functions were found to be a key mechanism system used to solve two or more linguistic conflicts caused by the process of manifesting language co-activation of bilingualism (Ellen Bialystok, 2015). Behavioral visual tracking, event-related potential and functional magnetic resonance imaging studies support the argument of co-language activation. The two implications are related to the viewpoint that this language conflict management is the basic mechanism for the bilingual effect on cognition. The first suggestion is that this effect is inherently available due to training in increasing experience frequency. Therefore, there is evidence that bilingual experience increases cognitive benefits.
This investigation discusses the question of “Is the brain organized differently in bilingual individuals?”. This question was brought upon living in a bilingual community at school, with both Arabic and English speakers. This essay will demonstrate the brain imaging techniques used to differentiate the monolingual brain from a bilingual brain, research studies, and the positive and negative outcomes toward a bilingual brain. Language constructs our relationship with the world arounds us in the ways we express ourselves, therefore what does it mean to be bilingual and monolingual? Bilingualism refers to an individual’s ability to speak two or more languages fluently even if one language is learned later on in life. However, monolinguals are
There are approximately 6,500 different languages in the world, and knowing more than one may help a lot more than just communicating with others or getting a better job. Whether a person is bilingual, multilingual, or even a polyglot learning languages can have massive impacts on a person’s brain. People are always looking for ways to be smarter, have more focus, and perform better on tests. Languages might be the answer. Scientists have found that learning languages can offset Alzheimer’s and dementia, increase brain size and connectivity, and improve overall brain function.
Many parents and teachers, now more than ever, are teaching children the importance of understanding and speaking more than one language. However, many children who speak more than one language have slight developmental delays in their syntax for both languages. However, the benefits of being bilingual far outweighs these very minor delays. There are many benefits to being bilingual. Recent studies done have even discovered that being bilingual may help protect our brains from developing diseases such as Alzheimer’s and other forms of dementia. Those of us who learned a second language during childhood have a better understanding for how language is structured and used, this understanding is called metalinguistic insight.
Learning a second language at a young age has long-term benefits that can be felt even in old age. As human’s age their brains atrophy, but bilingual people can delay the consequences of this damage. These individuals are constantly experiencing the world using two languages so, while a monolingual person remembers how to ride a bike in one language, a bilingual person stores that memory twice, once in their first language a once in their second. This allows bilingual
A third type of aphasia, global aphasia, results from damage to extensive portions of the language areas of the brain. “Individuals with global aphasia have severe communication difficulties and may be extremely limited in their ability to speak or comprehend language”. ()
No matter where you are in the world, you are taught about language. Whether it’s in your home learning your language or in school trying to learn a foreign language. Although while learning language the notion is never really thought about or brought up that the language and way we speak can influence the way we think and interact. Phycologist and neuroscientist alike have spent years, with multiple different tests to see if there is a connection between the various languages that are spoken and the way people not only think but also how they go about their daily lives. She writes to not only her colleagues and neuroscientists but also to anyone in the general public that is genuinely interested in the connection between
Finally, bilingualism offers a means of averting the natural decline of cognitive function and enhancing brain function during aging. This is due to keeping the cognitive mechanisms sharp and replacing damaged brain networks during aging. Researchers compared the brains of bilingual and monolingual patients with Alzheimer. The brains of “bilingual people showed a significantly higher degree of physical atrophy in regions commonly associated with Alzheimer’s disease” (Marian and Shook, 2012, p. 1). This suggests that the use of two languages protects bilinguals from the symptoms of the disease. Bilingualism itself does not directly affect Alzheimer’s disease, but the use of two languages provides a level of cognitive reserve, which enables
This trend was also prevalent in the right hemisphere for bilinguals however not seen in monolinguals (x = 56, y = -53, z = 42; Z-score = 3.4; P<0.001). Voxel-based morphometry revealed that overall proficiency correlated negatively with age of acquisition (P<0.01; r=-0.855) and second-language proficiency correlated with grey-matter density in exactly the same left inferior parietal region previously identified by a different study (x = -48, y = -59, z = 46; Z-score = 4.1; P<0.05). (Mechelli, 2004)
The purpose of this paper is to pursue one important and fundamental aim: language and the brain are purely inseparable since it allows us to perform essential tasks such as generating, comprehending and expressing speech. With damage to the brain, individuals can no longer perform such tasks which can ultimately lead to many types of language disorders. The focus of this paper is Broca’s aphasia, a language disorder characterized by the inability to produce written and spoken speech. Damage to the brain can cause many types of speech impairments as well as comprehension deficits.
There are more than 6500 language around the world. We cannot control or decide where we are going to be born or we cannot decide our mother language. But we can choose which language we are going to use as our second language. The existence of large numbers of people who speak more than one language but who do not exhibit native-like control in both languages raises the question of how proficient a person must be to be classed as bilingual. Bilingualism may be defined as having some ability to use two or even more languages. Being of bilingual has practical benefits in globalize world and it is not limited to having conversations with more people around. In 1922 the philosopher Ludwig Wittgenstein said, “The limits of my language mean
