Language

Language

How a person communicates is a complex mental process. Grammar is used in this process. Grammar is defined as “the system of rules that determine how our thoughts can be expressed” (McGraw-Hill, 2011 p.174). Most people acquire the basics of communication without being aware. The process of language begins in infancy and progresses throughout the early years. The complexity of communication, as well as the cognitive processes involved in the development and use of language, is an important topic in cognitive psychology.

Language and Lexicon

Language is a method of communicating thoughts and feelings. Communicating through language is by a system of symbols, usually sounds, signs or written symbols, arranged according to rules of grammar (Wood, Wood,  & Boyd, 2011). In order to understand the structure and rules of language, researchers study psycholinguistics. Psycholinguistics is the study of how language is “acquired, produced and used” (Wood, Wood,  & Boyd, 2011 p.230). Lexicon is also important to a person’s use of language. Lexicon is a mental dictionary of language (Willingham, 2007). The lexicon contains several representations of known words. These representations include pronunciation, spelling and part of speech. The lexicon aids a person in the matching process of a spoken word and its meaning.

Key Features of Language

Language is complex but has key characteristics (Williamson, 2009). Language has systematicity. This means that language has a regular, orderly method of communicating ideas, thoughts and emotions. Language is governed by rules. Language is structure dependent. There is a patterned structure as to how language is produced. Displacement is found in language (Williamson, 2009). Displacement allows a person to think of and communicate about something or someone that is not present. These characteristics can be found in all the languages of the world and make all languages similar.

Levels of Language Structure

There are four levels of language structure. These four levels are phonemes, morphemes, syntax and semantics. Phonemes are the smallest units of spoken language. These are sounds used to form words. Among the world’s languages, more than eight hundred phonemes have been identified (McGraw-Hill, 2011). However, only around fifty-two phonemes are used in the English language. Phonemes do not provide meaning; morphemes do. Morphemes are comprised of two or more phonemes (Wood, Wood,  & Boyd, 2011). There are exceptions to this in the English language such as the words I and a. Morphemes are the words of a language. Morphemes can be singular or plural. Two morphemes can be combined to create words. The next level of language is syntax. In this level, sentences and phrases are formed. Each language has its own rules of how sentences are formed. In English, the adjective comes before the noun. However, in Spanish the noun comes before the adjective. Semantics is the fourth level of language. In this level, meaning is derived from words and sentences. This is commonly referred to as text. The rules of semantics allow a person to use words to express his or her thoughts (McGraw-Hill, 2011). 

Language Processing

Language comprehension precedes language production (McGraw-Hill, 2011). Language processing begins around three months old. At this time a baby begins to babble. Babbling is meaningless, speech like sounds and lasts until usually a year old. Researchers say that babies that babies can produce the sounds found in all languages as well as can distinguish among all the known phonemes (McGraw-Hill, 2011). As the babbling stage advances, the infant begins to sound more like the language spoken in their environment. The infant’s ability to recognize all the phonemes also decreases. Neurons in the brain reorganize to respond only to the specific phonemes routinely heard therefore specializing in their own language. Some studies show that if a child is isolated from communications have a difficulty learning the language. This deficit is difficult to overcome (McGraw-Hill, 2011). After age one, children stop producing sounds not in their language and learn the more complicated forms of language. A child’s vocabulary increases and they speak in telegraphic speech. Telegraphic speech is sentences where words not critical to the message are left out (McGraw-Hill, 2011). There are several reasons as to why language processing becomes difficult. One is differences in phonemes. This reason makes it difficult for a person to learn a different language. Word perception is another reason language processing is difficult. Words can be taken in different contexts. 

Language Acquisition Theories

There are three main theories of language acquisition (McGraw-Hill, 2011). The first of these is the Learning Theory. This theory suggests that language acquisition follows the principles of reinforcement and conditioning. However, this theory does not explain how children learn language without being reinforced or conditioned.  The second theory is the Nativist Theory. This theory states that a genetically determined, innate mechanism directs language acquisition. This means that a person has a natural instinct to learn language. Noam Chomsky developed the theory of universal grammar (McGraw-Hill, 2011). He believed that all the world’s languages share a common underlying structure. Chomsky also developed the theory that a person has a language-acquisition device (McGraw-Hill, 2011). This device was in the neural system of the brain. Neuroscientists have concluded that the ability to use language is tied to neurological developments (McGraw-Hill, 2011).  The third theory was the Interactionist theory. This theory states that language is developed through genetically predisposition and environment. The interactionist theory can be supported by research done on children who were isolated from language. These children have the genetic predisposition to learn language, but lack the environmental cues to aid their learning.

Conclusion

In conclusion, language is a complex process. Language acquisition begins soon after birth and continues well into childhood. Language processing is done through the learning of the levels of structure. It is believed that all languages have some similar characteristics. Cognitive psychologists research to understand the process of language and the structure of language. In fact, psychologists have devoted considerable time to the study of language (McGraw-Hill, 2011). Language is an important process in humans.
