Bilingualism/multilingualism is a natural phenomenon worldwide. Unwittingly, however, monolingualism has been used as a standard to characterize and define bilingualism/multilingualism in linguistic research. Such a conception led to a “fractional,” “irregular,” and “distorted” view of bilingualism, which is becoming rapidly outmoded in the light of multipronged, rapidly growing interdisciplinary research. This article presents a complex and holistic view of bilinguals and multilinguals on conceptual, theoretical, and pragmatic/applied grounds. In that process, it attempts to explain why bilinguals are not a mere composite of two monolinguals. If bilinguals were a clone of two monolinguals, the study of bilingualism would not merit any substantive consideration in order to come to grips with bilingualism; all one would have to do is focus on the study of a monolingual person. Interestingly, even the two bilinguals are not clones of each other, let alone bilinguals as a set of two monolinguals. This paper examines the multiple worlds of bilinguals in terms of their social life and social interaction. The intricate problem of defining and describing bilinguals is addressed; their process and end result of becoming bilinguals is explored alongside their verbal interactions and language organization in the brain. The role of social and political bilingualism is also explored as it interacts with individual bilingualism and global bilingualism (e.g., the issue of language endangerment and language death). Other central concepts such as individuals’ bilingual language attitudes, language choices, and consequences are addressed, which set bilinguals apart from monolinguals. Language acquisition is as much an innate, biological, as social phenomenon; these two complementary dimensions receive consideration in this article along with the educational issues of school performance by bilinguals. Is bilingualism a blessing or a curse? The linguistic and cognitive consequences of individual, societal, and political bilingualism are examined.
The distinction between representations and processes is central to most models of the cognitive science of language. Linguistic theory informs the types of representations assumed, and these representations are what are taken to be the targets of second language acquisition. Epistemologically, this is often taken to be knowledge, or knowledge-that. Techniques such as Grammaticality Judgment tasks are paradigmatic as we seek to gain insight into what a learner’s grammar looks like. Learners behave as if certain phonological, morphological, or syntactic strings (which may or may not be target-like) were well-formed. It is the task of the researcher to understand the nature of the knowledge that governs those well-formedness beliefs. Traditional accounts of processing, on the other hand, look to the real-time use of language, either in production or perception, and invoke discussions of skill or knowledge-how. A range of experimental psycholinguistic techniques have been used to assess these skills: self-paced reading, eye-tracking, ERPs, priming, lexical decision, AXB discrimination, and the like. Such online measures can show us how we “do” language when it comes to activities such as production or comprehension. There has long been a connection between linguistic theory and theories of processing as evidenced by the work of Berwick (The Grammatical Basis of Linguistic Performance). The task of the parser is to assign abstract structure to a phonological, morphological, or syntactic string; structure that does not come directly labeled in the acoustic input. Such processing studies as the Garden Path phenomenon have revealed that grammaticality and processability are distinct constructs. In some models, however, the distinction between grammar and processing is less distinct. Phillips says that “parsing is grammar,” while O’Grady builds an emergentist theory with no grammar, only processing. Bayesian models of acquisition, and indeed of knowledge, assume that the grammars we set up are governed by a principle of entropy, which governs other aspects of human behavior; knowledge and skill are combined. Exemplar models view the processing of the input as a storing of all phonetic detail that is in the environment, not storing abstract categories; the categories emerge via a process of comparing exemplars. Linguistic theory helps us to understand the processing of input to acquire new L2 representations, and the access of those representations in real time.
Words are the backbone of language activity. An average 20-year-old native speaker of English will have a vocabulary of about 42,000 words. These words are connected with one another within the larger network of lexical knowledge that is termed the mental lexicon. The metaphor of a mental lexicon has played a central role in the development of theories of language and mind and has provided an intellectual meeting ground for psychologists, neurolinguists, and psycholinguists. Research on the mental lexicon has shown that lexical knowledge is not static. New words are acquired throughout the life span, creating very large increases in the richness of connectivity within the lexical system and changing the system as a whole. Because most people in the world speak more than one language, the default mental lexicon may be a multilingual one. Such a mental lexicon differs substantially from a lexicon of an individual language and would lead to the creation of new integrated lexical systems due to the pressure on the system to organize and access lexical knowledge in a homogenous manner. The mental lexicon contains both word knowledge and morphological knowledge. There is also evidence that it contains multiword strings such as idioms and lexical bundles. This speaks in support of a nonrestrictive “big tent” view of units of representation within the mental lexicon. Changes in research on lexical representations in language processing have emphasized lexical action and the role of learning. Although the metaphor of words as distinct representations within a lexical store has served to advance knowledge, it is more likely that words are best seen as networks of activity that are formed and affected by experience and learning throughout the life span.
Diglossia refers to a situation where two linguistic varieties coexist within a given speech community. One variety, labeled the ‘high variety’, is used in formal domains including education, while the other variety, labeled the ‘low variety’, is used principally in instances of informal extemporaneous communication. The domains of use, however, are not strictly separate and especially so with the increase in electronic modes of communication. This results in what has been described as diglossic code-switching, and the gradual encroaching of, in the case under consideration here, vernacular Arabic upon the domains of use of Standard Arabic. While the genetic relationship between the two varieties is central in the definition of a classical diglossic situation as in the case of Arabic, the concept of diglossia has often been extended in the literature to cover situations of a functional distribution between languages that are genetically distant, such as with the situation of Spanish and Guaraní in Paraguay. In North Africa, vernacular Arabic is in a classical diglossic distribution with Standard Arabic, while the Berber languages are often described as existing in a situation of extended diglossia with Arabic. However, distinguishing between diglossia as it exists between the Arabic dialects and Standard Arabic and the situation of bilingualism that involves Arabic, Berber, and European languages provides the best framework for describing the linguistic situation in North Africa. Diglossia is a key element in understanding the mechanisms of the region’s language contact and change as it plays a central role in shaping language attitude, language policy, and language planning.

We summarize findings from across a range of methods, including behavioral measures of overall processing speed and accuracy, electrophysiological indices that tap into the early time course of language processing, and neural measures using structural and functional imaging. We argue that traditional claims about rigid constraints on the ability of late bilinguals to exploit the meaning and form of the morphology and morphosyntax in a second language should be revised so as to move away from all or none command of structures motivated from strict dichotomies among linguistic categories of morphology. We describe how the dynamics of morphological processing in neither monolingual or bilingual speakers is easily characterized in terms of the potential to decompose words into their constituent morphemes and that morphosyntactic processing is not easily characterized in terms of categories of structures that are learnable and those that are unlearnable by bilingual and nonnative speakers. Instead, we emphasize the high degree of variability across individuals and plasticity within individuals in their ability to successfully learn and use even subtle aspects of a second language. Further, both of the bilingual’s two languages become active when even one language is engaged, and parallel activation has consequences that shape both languages, thus their influence is not in the unidirectional manner that was traditionally assumed. We briefly discuss the nature of possible constraints and directions for future research.

Language attrition is the loss of linguistic abilities or the regression of specific grammatical properties and overall fluency in linguistic skills. It impacts language use, lexical access, and grammatical integrity. Non-pathological attrition is natural in situations of language contact and bilingualism and can occur in the first, native, language as well as in a second language. As a gradual and dynamic process of accommodation that occurs when bilinguals use the second language extensively, attrition is a highly individualized phenomenon and hard to predict a priori. If attrition eventually happens, it affects individuals differently, with some exhibiting more widespread loss than others. Two factors that determine the extent of language attrition in bilinguals are the availability of input and the age of the individual at the onset of the reduction in input in their native language. An important question is whether attrition mainly occurs at the level of processing or whether it affects actual linguistic competence. Theoretical approaches to attrition have emphasized its relationship with L1 acquisition, the selectivity of attrition by linguistic modules, the effects of language use on memory, and the interplay between the L1 and the L2 along the life span. We still lack understanding of how attrition affects linguistic representations and processing and the external and individual cognitive factors that modulate, predict, or prevent attrition in bilinguals. Morphological attrition is far more common and extensive in children than in adults and it manifests itself in a variety of ways: morphophonemic leveling, morphological simplification, including omission of required morphology in obligatory contexts, paradigmatic reduction, simplification/reduction of suffixal allomorphy, regularization of irregular forms, and the replacement of synthetic forms for analytic/periphrastic forms. Morphological attrition has often been discussed in the context of language death and language loss at the community level for both child and adult bilinguals. The scant empirical evidence to date seems to indicate that the processes of omission, regularization, and suppletion that are common in attrition occur regardless of the dominant morphological type of a language. Both inflectional and derivational morphology are affected under language attrition and seem to undergo similar processes of reduction and simplification, regardless of the morphological type of the language. Within inflectional morphology, nominal morphology (gender, number, case) is more prone to attrition in the actual number of occurrences than verbal morphology (agreement, tense, aspect, mood), and attrition occurs more rapidly and extensively.
Connectionism is an important theoretical framework for the study of human cognition and behavior. Also known as Parallel Distributed Processing (PDP) or Artificial Neural Networks (ANN), connectionism advocates that learning, representation, and processing of information in mind are parallel, distributed, and interactive in nature. It argues for the emergence of human cognition as the outcome of large networks of interactive processing units operating simultaneously. Inspired by findings from neural science and artificial intelligence, connectionism is a powerful computational tool, and it has had profound impact on many areas of research, including linguistics. Since the beginning of connectionism, many connectionist models have been developed to account for a wide range of important linguistic phenomena observed in monolingual research, such as speech perception, speech production, semantic representation, and early lexical development in children. Recently, the application of connectionism to bilingual research has also gathered momentum. Connectionist models are often precise in the specification of modeling parameters and flexible in the manipulation of relevant variables in the model to address relevant theoretical questions, therefore they can provide significant advantages in testing mechanisms underlying language processes.
