Abstract

As multiple researchers approached bilingualism from different angles, it has been shown throughout complex processes that it is a field that must be held with precaution. The distinction of all elements involved in its study and the understanding of this complex process has been proved problematic. Yet, with the reported research of numerous linguists and with more defined methodology it has been possible to distinguish various types of bilingualism and its relation with mental processes. On the one hand, bilingualism negatively affects the mind development. Whereas on the other hand it has a positive influence on cognitive performance. Counterparts have explored the numerous areas around this topic in order to understand a bit more the developmental mechanism and behaviour of both monolingual and bilingual individuals. Evidently, the study of bilingualism aims to clarify major titles and answer inevitable questions that turn around this subject. Therefore, providing exact answers is inevitably problematic. Yet, positive reports about bilingualism's influence on cognitive development

outnumber those that suggest negative effects,

elements are of a great impact .

General Introduction

Background of The Study Merely, bilingualism was born from the contact and communication of individuals coming from different nations. Where migration and globalization played a great role in the spreading of this phenomenon. Bilingualism has been the subject of interest of many linguists. Aiming to understand the differences between bilinguals and their monolingual peers. In history, In addition to the research of Peal and Lambert in 1962 that influenced radically most assumptions and beliefs concerning bilingualism. Evidence of language proficiency levels in L1 and L2 proved to be important standards in the study of bilinguals' behaviour, as well as further social factors influencing the performance and development of individuals. Further approaches about bilingual influence on cognitive development have been author of many problematic questions. where some reported negative effects as poor vocabulary and less proficiency in languages. and other reports better cognitive flexibility . In sum one must take into consideration the various outcomes and influencing elements so as to make clearer distinction when investigating the effects of bilingualism on cognitive development. This research will focus on possible effects of bilingualism on cognitive development and to find out which of the positive or negative effects is prominent.

Research Questions and Hypothesis In order to discuss matters related to bilingualism and its impact on cognitive development, we set out to answer the following questions: - What are the different definitions of bilingualism? And why is it defined differently? - On what basis bilinguals are differentiated and classified ? - What are possible negative effects of bilingualism on cognitive development ? - What are the benefits of being bilingual in relation to cognitive abilities and educational/ social development ? On the basis of these questions, the following hypothesis is put forward: Bilingualism has more positive effects on cognitive abilities than negative effects .

Section I: Definition of Terms 1.Bilingualism and Bilinguals

During the twentieth century, many approaches had dealt with bilingualism and the definition of a bilingual - even if it seems easy - it is rather a complex and ambiguous task. Linguists explored this field from different angles for the purpose of investigating and better understanding the features and difficulties related to this topic.

Merely, bilingualism is the ability to use two languages. However, defining bilingualism is problematic since individuals with varying bilingual characteristics may be classified as bilingual. Therefore, definitions of bilingualism range from a minimal proficiency in two languages, to an advanced level of proficiency which allows the speaker to function and appear as a native-like speaker of two languages. It is said that a person may describe themselves as bilingual but may mean only the ability to converse and communicate orally. Others may be proficient in reading in two or more languages . Again, a person may be bilingual by virtue of having grown up learning and using two languages simultaneously. Or also may become bilingual by learning a second language sometime after their first language. In sum, to be bilingual means different things to different people (Franson, 2009).

In defining bilinguals, Gottardo and Grant (2008) hold that: The definition of bilingualism is more complex than a simplistic ―yes/ no‖ categorization. Definitions of bilingualism must include the degree of

3

proficiency in each language and circumstances under which each language is learned. Even outwardly simple questions such as what it means to ―know‖ a language must be considered. Factors that facilitate or hinder bilingualism must be considered. (p.5)

Further, Butler and Hakuta (2006) in their attempt of defining bilingualism state that :

Bilinguals are often broadly defined as individuals or groups of people who obtain the knowledge and use of more than one language. However, bilingualism is a complex psychological and socio-cultural linguistic behaviour and has multi-dimensional aspects. There is no agreed-upon definition of bilingualism among researchers. (p.114)

Genesee (2007) argues that a definition of bilingualism should include the age of the first exposure to language, regularity and the extent of exposure to each language. In that very same year, Wei listed four concepts which should be taken into consideration in the definition of a bilingual: first, the age and way of the acquisition of a language ; second, proficiency level in specific languages; third , domains of language use; and fourth, selfidentification and attitude.

4

Gottardo, and Grant (2008) also assert that : "carefully defining degrees of bilingualism in each circumstance and for each learner is important because educational decisions depend on the accuracy of these definitions" (p.5)

It cannot be but clear that there is no single interpretation able to define bilingualism and bilinguals. As has been said previously, one must take into account the fact that there is different points and views from which one can perceive bilingualism. Hence, grasping an exact detailed and truthful definition of it ,is difficult. One must consider the age factor as well as the manner and amount of the exposure to the language , and again when and what the language is used for . To end up with concluding that defining bilingualism requires paying attention to all susceptible influencing details related to the field .

2.Typology of Bilingualism and Classification of Bilinguals

According to Butler and Hakuta, Bilingualism

have multiple dimensions. These

dimensions are in fact characteristics of individual bilinguals that were observed to differ from one another. Therefore, it is important to take into account one dimension at the time which means focussing on a certain one in order to be able to elaborate an adequate classification of bilinguals . As they assert : " bilingual individuals can be classified on the basis of different dimensions both at the individual and social levels" (p.118 ).

Again , there are various types into which bilinguals may fall . Seeing individual bilinguals from different dimensions cleared the existence of more than one type. In the purpose of classifying those bilinguals into distinct categories, one must concentrate on specific dimensions so as to elaborate a clearer distinction between them.

Bilingual's classification encompasses numerous categories . We find studies based on individual's proficiency in language, for instance that of Pearl and Lambert which distinguished between two types : Balanced and unbalanced or (dominant). Bilinguals of the first category, or balanced bilinguals are those with similar degree of proficiency in both languages. And bilinguals of the second category, or unbalanced (dominant) bilinguals, are those whose proficiency in one language is higher than their proficiency in the other language (s) . (Pearl and Lambert , 1962).

6

From another dimension, in 1953, a study based on the organization of linguistic codes in relation to meaning units. Weinreich classified bilinguals into three categories : the first was named compound, the individuals of this category possess two distinct sets of linguistic codes ; each language has its own linguistic code . The second one, as coordinate; this category

counts individuals with linguistic codes organized separately into two sets of

meaning unites .The third category encloses subordinate bilinguals , in which linguistic codes in the first language (L1) are presumed to be interpreted through the second language (L2) and the existent two sets of meaning unites are accessible only through the first language (L1). (Weinreich, 1953)

Moreover, there is Genesee's study based on the age of acquisition, have set out early and late bilinguals (Genesee et al,1978). While Hamers and Blanc stated that early bilinguals acquire both languages in a common family context. whereas Late bilinguals acquire the first language in their family context and a second language in school . Again, from early bilingualism derive Simultaneous and Consequential or consecutive bilingualism (Hamers and Blanc, 1989). The first category regroups bilinguals who simultaneously acquire equivalent skills in both languages , i.e., learning two languages at the same time. While in the second category, bilinguals are said to acquire the second language after the first one but with the acquisition still taking place during childhood . i.e., the acquisition of one language after another in early age.

7

Linguists have classified bilingualism and bilinguals into different types according to observations they collected through research. Based on aspects and emphasis on proficiency, linguistic codes and meaning units, or again measured to the age of the acquisition of the languages. All in the aim of understanding bilinguals' development . But also they were able to define characteristics of Second Language Acquisition (SLA). And possible outcomes related to levels of proficiency, semantic representation and cultural identities. Moreover, they observed related issues in educational implications.

Lambert, 1974 based on Functional ability distinguished from the one hand between Incipient, receptive and productive bilingualism. Again based on the effects of the second language learning on the retention of the first language from the other hand ,between additive Bilinguals, those who have the ability enhance their L2 without losing L1 proficiency and subtractive bilinguals whose L2 was acquired or learned at the expense of losing their L1 (Lambert, 1974-1975).

On the basis of Language status and learning environment, in 1977, distinguished Folk Bilinguals whose own

Fishman

language does not have a high status in the

society they reside in, from Elite bilinguals who speak a dominant language in a given society and another language which gives them additional value. also based on dimensions similar to those proposed by Fishman (1977), Valdés and Figueroa in 1994 differentiated between Circumstantial and Elective Bilinguals.

8

In addition, Butler and Hakuta (2008) have affirmed :

Dimensions of bilingualism are continuous and not simply categorical constructs. One cannot draw clear boundaries between different types of bilinguals within a given dimension. Take, for instance, the dimension of proficiency. There could be a wide range of combinations of proficiencies in two languages (p.118)

One more item is to be mentioned in this scope, that is the fact that one’s bilingual profile is susceptible to change with the time for the reason that bilingualism is not static but dynamic, according to Butler and Hakuta (2008) , individual may lose one of the skills' proficiency in their primary language once they start engaging in more activities in their second language.

Finally

one must

acknowledge the complexity of bilingualism and that the

classification of individual bilinguals depends much on the

multi-dimensions of this

linguistic behaviour in addition to external influencing circumstances as environmental and social factors.

3. Cognitive Performance

It is important to introduce the notion of cognition before getting into further detailed aspects of the relation between bilingualism and cognitive performance . According to a dictionary definition of the word cognition it is explained that " it is the mental act or process by which knowledge is acquired, including perception, intuition, and reasoning". (Collins, 2000).

In other words, Cognitive performance is our ability to acquire and use that knowledge. However behind such simple terms lays a complex related brain-based skills that individuals use in the performance of every action without realizing it . Perception through human senses , intuition, and also decision making and language skills are all parts of cognition. cognitive processes have less to do with any actual knowledge , but instead are about our ability to use that knowledge to direct and adapt actions towards goals.

Back in history, Piaget's first publication of his theory of children's cognitive development took place in the 1920's. Though his work did not become prominent until the mid-twentieth century, he suggested as well

his own theory about children's moral

development. He recognized that this latter is closely tied to moral development and he was interested in the way children's thoughts about morality change over time. For this purpose, he investigated cognitive development in children. (Oswalt, 2008) 11

Piaget's stage theory describes the cognitive development of children. It encloses four main stages defined by age and mental abilities. The first stage is called The Sensorimotor Stage. It is the stage in which, infants and toddlers acquire knowledge through their sensory experiences and their manipulation of objects. Second, The Preoperational stage. At this stage, kids learn through pretends play but still struggle with logic and taking the point of view of other people . The Third Stage is The Concrete Operational Stage . kids at this point of development start to think in a more logical way but their thinking can also be very rigid. They tend to struggle with abstract and hypothetical concepts. The final stage is The Formal Operational Stage, it involves an increased logic, the ability to use deductive reasoning, and the understanding of abstract ideas.(Oswalt, 2008)

Since language skills are all parts of cognition and from the stages of cognitive performance and development ,in addition to further approaches we found that bilingualism or multilingualism and cognitive performance are related while one affects the other in different ways.

According to Bialystok in 2011, bilingualism and cognition-based research highlight implications in individual processes of cognition in order to show the impact of bilingualism instead of the way particular languages and combinations of languages influences the thought processes of their speakers.

12

However, interrogative statements take place in this area of research. The studies based on individual bilinguals has shown a difference between their cognitive development and that of their monolingual mates. So as necessary observations about the relation between bilingualism and cognitive development

Section II: The Effects of Bilingualism on Cognitive Development

1. Bilingualism and Negative Cognitive Effects

With the assertion of several previous approaches, Bilingualism has been proved to affect cognitive performance in a negative way. From previous research, Hamers and Blanc (2000) point out that, whereas the biographies suggested a well-balanced development of the bilinguals’ languages, psychometric tests of the same period claimed that bilingualism had negative effects on children’s cognitive development. Another conducted study by Hoff et al. (2011) on bilingual and monolingual children. where monolinguals were only exposed to English while bilinguals were exposed to by English and Spanish. The research showed that children who are exposed to two languages simultaneously do not typically acquire each language at the same rate as children only exposed to one language.

In the early approaches Pintner and Keller (1922) refer to 'linguistic handicap' in bilingual children, and Saer (1923) to 'mental confusion', claiming that bilingual children had lower IQ values than their monolingual peers.

in other works E. Bialystok and Craik 2011 reveal that speaking two languages created retardation in children . And Studies of vocabulary knowledge have reported lower scores for bilinguals in each language than for monolingual speakers of that language, and this deficit appears at all ages across the lifespan (Bialystok, 2001). 14

E. Bialystok and Craik (2011) argue that

In a study examining receptive vocabulary scores in English for over 1,700 children between the ages of 3- and 10-years old, monolingual children obtained higher scores than bilingual children at every age, even though all the bilingual children were fluent in English and used it daily at school [Bialystok, Luk, Peets, & Yang, in press]. (p.8)

In addition study reported that dual language input affected both the children’s grammatical development as well as vocabulary (Hoff et al.2011) .These results agrees with Bialystok’s study on children aged between 3 and 10,investigating their English receptive vocabulary. Children who spoke English and with another language scored lower on the tests than their monolingual peers. Despite these results, Bialystok (2010) maintains that

there is no reason to believe that bilingual children have a smaller overall vocabulary – in fact, their combined vocabulary may be larger than that of monolinguals – or that they have poorer communicative ability than monolinguals, only that their vocabulary is distributed across two languages. (p. 561 )

15

The negative effects of bilingualism on cognitive development found across research, are

the proof of the fact that bilingualism can also affect negatively the cognitive

performance. It is also important to clarify that these results were not observed only in children but in adults as well. What was referred to as mental confusion and linguistic handicap as well as vocabulary deficiency is essentially related to individuals themselves i.e. ; not the amount or number of languages. This brings us again to the questions asked before concerning the effect of language on mind., to come up to conclude that language deficiency in bilinguals is not directly due to the number of languages one uses but in the amount and manner a bilingual individual uses it.

16

2. Bilingualism and cognitive advantages

Responses to the question investigating the impact of the number of languages on human mind emphasized the negative consequences of bilingualism . it was surprising when a radically different answer was offered by Peal and Lambert (1962); showing that bilingual francophone children in Montreal outperformed monolingual English-speaking children on a wide variety of measures.( Bialystok and Craik , p.3.)

In Bilingual Mind, Bialystok and Craik state :" Studies seeking evidence for bilingual effects on development began with the conservative assumption that any detectable effect of a linguistic experience would be found in the domain of linguistic competence." (p.3).

Bilingual students were observed to be cognitively more developed , as having divergent and more creative thinking (Hudson, 1968), having greater meta-linguistic awareness, asserted by Bialystok as " the explicit knowledge of linguistic structure and the ability to access it intentionally." In addition to cognitive control of linguistic processes (Bialystok, 1987 ; Galambos and Hakuta, 1988), and increased communicative sensitivity (Genesee, Tucker, and Lambert, 1975). But bilinguals must possess age-appropriate levels of competence in two languages in order to achieve these cognitive advantages.

After the publication of the Peal and Lambert study in 1962, further research was conducted implying the same results, or a positive effect on children’s cognition caused by 17

bilingualism. Most studies have provided empirical evidence on the cognitive advantage among bilingual children compared with their monolingual counterparts, particularly in high control tasks requiring increased cognitive flexibility . This flexibility can be tested with changing task demands which are unpredictable or novel to the participant (Bialystok, 1999).

Deán (2003) defines flexible cognition as:

The dynamic construction and modification of representations and responses based on information (i.e., similarities, cues, relations) selected from the linguistic and non-linguistic environment. That is, when there is a range of plausible ways to understand and respond to a problem, flexible thinkers select patterns that limit this range. The selected information must change over time as a function of shifting task demands. That is, as new problems and circumstances are imposed by the environment, the cognitive focus should shift to new, pertinent information. (pp. 275 –276)

and with changing unpredictable or novel task demands this flexibility can be tested .

Again, Based on illustrative experiment by Bialystok and colleagues (2004) involving several reaction-time (RT) conditions, E. Bialystok stated "The Result suggests that bilingualism may protect against age-related cognitive decline at least in the ability to inhibit the disruptive effects of misleading stimuli. "(p.7)

Also positive relationship exists between bilingualism and various abilities. For example, a positive relationship between bilingualism and the students’ ability to think 18

abstractly about language (a skill that has been called meta-linguistic ability and is hypothesized to be related to reading ability in elementary school students). We also found a positive relationship between bilingualism and nonverbal thinking as measured by a standard test of intelligence.( Hakuta, 1985)

In a nutshell, Bilingualism is majorly important for many cognitive, social and psychological reasons. From what has been said before and through several research and approaches: (Weinreich, 1953) ; (Peal & Lambert, 1962) ; ( Fishman &Figueroa, 1994) (Hamers &Blanc, 2000) ; ( Butler & Hakuta, 2008) ; ( Hoff et al, 2011). It was demonstrated that bilingualism's impact on cognitive performance is of a great positive importance. From cognitive development to more developed creative thinking and meta-linguistic awareness, Evidently bilingualism has positive effects on cognitive performance.

19

General Conclusion

To sum up what was previously stated, Bilingualism has been proved to be a complex field with no exact definition or standards, which makes it non measurable without due clarifications based upon multi-dimensions that finally constitute an easier way to understand this study . It is similar to related classification of bilingual individuals according to the typology of bilingualism.

It was shown that bilingualism and cognition were interrelated and affect the cognitive performance. while early research found that bilingualism affects negatively the cognitive development. It was the publication of Peal and Lambert's research in 1962 that disregarded these assertions and improved the way other researchers defined concepts and selected their subjects accordingly. Particularly , the distinction between types of bilinguals gave hints to coming approaches and importance to future investigations. It is this distinction that lead researchers to experiment the differences with clearer definitions and outcomes .

Most research indicated positive effects of bilingualism on cognitive performance because of the increase of attention and directed methodology of bilingualism. This positive influence consisted of increased cognitive flexibility when other research demonstrated better results on tasks requiring high control of language skills. But despite studies illustrating positive effects of bilingualism on cognitive development, some others indicated negative

20

outcomes . Mostly negative effects appear to affect individuals’ vocabulary . And have been reported to have poor vocabulary in comparison to

monolinguals. Also in late literacy

development . when L1 proficiency is not developed at the same time as L2 proficiency.

It can be deduced that, bilingualism is related to complicated set of factors that must be considered carefully when investigating this field. Concerning its effects on

cognitive

development, it remains the subject of struggles and fascination. Even with data collected up to this day one cannot yet expand all the sides of bilingualism. Nevertheless, it serves as a crucial input in stepping closely in direction of better understanding bilingualism.
