what do psychologists hope to learn by studying language development in children?
Learning Objectives
- Understand how the utilise of language develops
- Explain the human relationship between linguistic communication and thinking
Language is a communication organization that involves using words and systematic rules to organize those words to transmit information from ane individual to another. While language is a form of communication, non all communication is linguistic communication. Many species communicate with one another through their postures, movements, odors, or vocalizations. This communication is crucial for species that demand to interact and develop social relationships with their conspecifics. However, many people have asserted that it is linguistic communication that makes humans unique amidst all of the beast species (Corballis & Suddendorf, 2007; Tomasello & Rakoczy, 2003). This department will focus on what distinguishes language as a special grade of advice, how the use of language develops, and how language affects the way nosotros think.
Components of Language
Linguistic communication, be it spoken, signed, or written, has specific components: a lexicon and grammar. Lexicon refers to the words of a given language. Thus, lexicon is a language'southward vocabulary. Grammar refers to the set of rules that are used to convey significant through the apply of the lexicon (Fernández & Cairns, 2011). For instance, English grammar dictates that most verbs receive an "-ed" at the stop to signal past tense.
Try It
Words are formed by combining the various phonemes that make upward the language. A phoneme (e.g., the sounds "ah" vs. "eh") is a basic sound unit of a given language, and different languages have dissimilar sets of phonemes. Phonemes are combined to form morphemes, which are the smallest units of language that convey some type of pregnant (e.g., "I" is both a phoneme and a morpheme).
Effort It
We utilise semantics and syntax to construct language. Semantics and syntax are part of a language's grammer. Semantics refers to the process by which we derive pregnant from morphemes and words. Syntax refers to the style words are organized into sentences (Chomsky, 1965; Fernández & Cairns, 2011).
Nosotros utilize the rules of grammar to organize the dictionary in novel and creative ways, which allow us to communicate information near both concrete and abstruse concepts. We can talk near our immediate and appreciable surroundings likewise as the surface of unseen planets. We can share our innermost thoughts, our plans for the future, and debate the value of a college education. We can provide detailed instructions for cooking a meal, fixing a automobile, or building a fire. The flexibility that language provides to relay vastly different types of information is a property that makes linguistic communication so distinct as a mode of communication among humans.
Linguistic communication Development
Given the remarkable complexity of a language, one might expect that mastering a linguistic communication would be an especially arduous chore; indeed, for those of us trying to learn a second language as adults, this might seem to exist truthful. However, young children master language very speedily with relative ease. B. F. Skinner (1957) proposed that language is learned through reinforcement. Noam Chomsky (1965) criticized this behaviorist approach, asserting instead that the mechanisms underlying language acquisition are biologically determined. The use of language develops in the absence of formal instruction and appears to follow a very similar pattern in children from vastly dissimilar cultures and backgrounds. It would seem, therefore, that we are born with a biological predisposition to acquire a language (Chomsky, 1965; Fernández & Cairns, 2011). Moreover, it appears that there is a critical period for language acquisition, such that this proficiency at acquiring linguistic communication is maximal early in life; generally, as people age, the ease with which they learn and primary new languages diminishes (Johnson & Newport, 1989; Lenneberg, 1967; Singleton, 1995).
Children brainstorm to learn about linguistic communication from a very early age (Table 1). In fact, information technology appears that this is occurring even earlier nosotros are born. Newborns testify preference for their mother'due south voice and announced to exist able to discriminate between the language spoken by their mother and other languages. Babies are also attuned to the languages being used around them and show preferences for videos of faces that are moving in synchrony with the audio of spoken language versus videos that do not synchronize with the audio (Flower & Morgan, 2006; Pickens, 1994; Spelke & Cortelyou, 1981).
| Stage | Age | Developmental Linguistic communication and Communication |
|---|---|---|
| one | 0–3 months | Reflexive communication |
| 2 | 3–8 months | Reflexive advice; involvement in others |
| 3 | eight–thirteen months | Intentional communication; sociability |
| 4 | 12–18 months | First words |
| five | 18–24 months | Simple sentences of two words |
| half-dozen | two–three years | Sentences of three or more words |
| seven | 3–5 years | Complex sentences; has conversations |
Dig Deeper: The Instance of Genie
In the autumn of 1970, a social worker in the Los Angeles expanse found a 13-twelvemonth-old daughter who was existence raised in extremely neglectful and abusive weather condition. The girl, who came to exist known as Genie, had lived most of her life tied to a potty chair or confined to a crib in a small room that was kept closed with the curtains fatigued. For a little over a decade, Genie had virtually no social interaction and no admission to the outside world. As a result of these conditions, Genie was unable to stand up, chew solid food, or speak (Fromkin, Krashen, Curtiss, Rigler, & Rigler, 1974; Rymer, 1993). The police took Genie into protective custody.
Genie's abilities improved dramatically following her removal from her calumniating environment, and early on, it appeared she was acquiring linguistic communication—much afterward than would be predicted by critical period hypotheses that had been posited at the fourth dimension (Fromkin et al., 1974). Genie managed to amass an impressive vocabulary in a relatively short amount of time. However, she never adult a mastery of the grammatical aspects of language (Curtiss, 1981). Perhaps being deprived of the opportunity to learn language during a critical period impeded Genie's power to fully learn and use linguistic communication.
You may think that each linguistic communication has its own set of phonemes that are used to generate morphemes, words, and then on. Babies tin can discriminate amongst the sounds that make upward a linguistic communication (for example, they can tell the difference between the "s" in vision and the "ss" in fission); early on, they can differentiate between the sounds of all human languages, even those that do non occur in the languages that are used in their environments. However, by the fourth dimension that they are almost i year old, they can just discriminate among those phonemes that are used in the language or languages in their environments (Jensen, 2011; Werker & Lalonde, 1988; Werker & Tees, 1984).
After the first few months of life, babies enter what is known as the blathering stage, during which time they tend to produce unmarried syllables that are repeated over and over. As time passes, more variations appear in the syllables that they produce. During this time, information technology is unlikely that the babies are trying to communicate; they are just every bit probable to babble when they are alone as when they are with their caregivers (Fernández & Cairns, 2011). Interestingly, babies who are raised in environments in which sign language is used will also begin to testify babbling in the gestures of their hands during this stage (Petitto, Holowka, Sergio, Levy, & Ostry, 2004).
Generally, a kid'southward commencement give-and-take is uttered sometime betwixt the ages of 1 twelvemonth to 18 months, and for the side by side few months, the child will remain in the "i word" stage of language development. During this time, children know a number of words, but they only produce 1-word utterances. The kid'southward early vocabulary is limited to familiar objects or events, often nouns. Although children in this stage only make one-word utterances, these words often carry larger meaning (Fernández & Cairns, 2011). So, for example, a child saying "cookie" could be identifying a cookie or asking for a cookie.
As a child'due south dictionary grows, she begins to utter uncomplicated sentences and to larn new vocabulary at a very rapid step. In add-on, children begin to demonstrate a clear understanding of the specific rules that utilise to their language(s). Fifty-fifty the mistakes that children sometimes make provide evidence of just how much they understand about those rules. This is sometimes seen in the grade of overgeneralization. In this context, overgeneralization refers to an extension of a language rule to an exception to the rule. For case, in English, it is usually the case that an "southward" is added to the end of a word to indicate plurality. For example, nosotros speak of 1 domestic dog versus ii dogs. Young children will overgeneralize this rule to cases that are exceptions to the "add an due south to the end of the word" rule and say things like "those two gooses" or "three mouses." Clearly, the rules of the language are understood, even if the exceptions to the rules are nonetheless being learned (Moskowitz, 1978).

Language and Thinking
What Do You lot Call up?: The Pregnant of Language
Think about what you know of other languages; perchance you even speak multiple languages. Imagine for a moment that your closest friend fluently speaks more than 1 language. Practise you recall that friend thinks differently, depending on which linguistic communication is being spoken? You may know a few words that are not translatable from their original language into English. For instance, the Portuguese give-and-take saudade originated during the 15th century, when Portuguese sailors left home to explore the seas and travel to Africa or Asia. Those left behind described the emptiness and fondness they felt equally saudade (Figure 1). The word came to limited many meanings, including loss, nostalgia, yearning, warm memories, and promise. In that location is no single word in English language that includes all of those emotions in a unmarried description. Exercise words such equally saudade indicate that unlike languages produce different patterns of thought in people? What practice you think??
Figure 1. These 2 works of art depict saudade. (a) Saudade de Nápoles, which is translated into "missing Naples," was painted by Bertha Worms in 1895. (b) Almeida Júnior painted Saudade in 1899.
Language may indeed influence the style that we think, an thought known every bit linguistic determinism. 1 contempo demonstration of this phenomenon involved differences in the style that English and Standard mandarin Chinese speakers talk and think most time. English speakers tend to talk about time using terms that describe changes along a horizontal dimension, for case, saying something like "I'g running backside schedule" or "Don't get alee of yourself." While Mandarin Chinese speakers also describe fourth dimension in horizontal terms, it is not uncommon to also utilize terms associated with a vertical arrangement. For example, the past might be described as existence "upward" and the future as being "down." It turns out that these differences in language translate into differences in performance on cognitive tests designed to mensurate how quickly an individual tin recognize temporal relationships. Specifically, when given a series of tasks with vertical priming, Mandarin Chinese speakers were faster at recognizing temporal relationships between months. Indeed, Boroditsky (2001) sees these results equally suggesting that "habits in language encourage habits in thought" (p. 12).
Language does not completely determine our thoughts—our thoughts are far also flexible for that—but habitual uses of language can influence our habit of thought and action. For instance, some linguistic practise seems to be associated even with cultural values and social institution. Pronoun drop is the case in betoken. Pronouns such every bit "I" and "you" are used to stand for the speaker and listener of a speech in English. In an English judgement, these pronouns cannot be dropped if they are used as the field of study of a sentence. So, for case, "I went to the moving picture terminal nighttime" is fine, just "Went to the movie last dark" is not in standard English. Even so, in other languages such every bit Japanese, pronouns tin can be, and in fact frequently are, dropped from sentences. It turned out that people living in those countries where pronoun drop languages are spoken tend to have more than collectivistic values (e.thousand., employees having greater loyalty toward their employers) than those who use not–pronoun drop languages such as English language (Kashima & Kashima, 1998). It was argued that the explicit reference to "you" and "I" may remind speakers the distinction betwixt the self and other, and the differentiation betwixt individuals. Such a linguistic practice may act equally a abiding reminder of the cultural value, which, in plow, may encourage people to perform the linguistic do.
One group of researchers who wanted to investigate how language influences idea compared how English language speakers and the Dani people of Papua New Guinea call back and speak about color. The Dani accept two words for colour: one word for lite and one word for dark. In contrast, the English has xi color words. Researchers hypothesized that the number of color terms could limit the ways that the Dani people conceptualized colour. However, the Dani were able to distinguish colors with the same power equally English speakers, despite having fewer words at their disposal (Berlin & Kay, 1969). A recent review of research aimed at determining how language might affect something like color perception suggests that linguistic communication can influence perceptual phenomena, especially in the left hemisphere of the brain. You may call back from earlier chapters that the left hemisphere is associated with language for most people. Yet, the correct (less linguistic hemisphere) of the brain is less affected by linguistic influences on perception (Regier & Kay, 2009)
