Babbling
A babbling infant, age 6 months, making ''ba'' and ''ma'' sounds Babbling is a stage in child development and a state in language acquisition during which an infant appears to be experimenting with uttering articulate sounds, but does not yet produce any recognizable words. Babbling begins shortly after birth and progresses through several stages as the infant's repertoire of sounds expands and vocalizations become more speech-like. Infants typically begin to produce recognizable words when they are around 12 months of age, though babbling may continue for some time afterward. Babbling can be seen as a precursor to language development or simply as vocal experimentation. The physical structures involved in babbling are still being developed in the first year of a child's life. This continued physical development is responsible for some of the changes in abilities and variations of sound babies can produce. Abnormal developments such as certain medical conditions, developmen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manual Babbling
Manual babbling is a linguistic phenomenon that has been observed in deaf children and hearing children born to deaf parents who have been exposed to sign language. Manual babbles are characterized by repetitive movements that are confined to a limited area in front of the body similar to the sign-phonetic space used in sign languages. In their 1991 paper, Pettito and Marentette concluded that between 40% and 70% of deaf children's manual activity can be classified as manual babbling, whereas manual babbling accounts for less than 10% of hearing children’s manual activity. Manual Babbling appears in both deaf and hearing children learning American Sign Language from 6 to 14 months old (Marschark, 2003). Manual babbling is not to be confused with movement that is motor-driven and non-communicative/common communicative in nature. Babbling occurs during the same period of development when an infant is also trying to establish a sense of their spatial orientation and cognition. This re ...

Phonological Development
Phonological development refers to how children learn to organize sounds into meaning or language (phonology) during their stages of growth. Sound is at the beginning of language learning. Children have to learn to distinguish different sounds and to segment the speech stream they are exposed to into units – eventually meaningful units – in order to acquire words and sentences. One reason that speech segmentation is challenging is that unlike between printed words, no spaces occur between spoken words. Thus if an infant hears the sound sequence “thisisacup,” they have to learn to segment this stream into the distinct units “this”, “is”, “a”, and “cup.” Once "cup" is able to be extracted from the speech stream, the child has to assign a meaning to this word. Furthermore, the child has to be able to distinguish the sequence “cup” from “cub” in order to learn that these are two distinct words with different meanings. Finally, the child has to learn to pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Language Development
Language development in humans is a process which starts early in life. Infants start without knowing a language, yet by 10 months, babies can distinguish speech sounds and engage in babbling. Some research has shown that the earliest learning begins in utero when the fetus starts to recognize the sounds and speech patterns of its mother's voice and differentiate them from other sounds after birth. Typically, children develop receptive language abilities before their verbal or expressive language develops. Receptive language is the internal processing and understanding of language. As receptive language continues to increase, expressive language begins to slowly develop. Usually, productive/expressive language is considered to begin with a stage of pre-verbal communication in which infants use gestures and vocalizations to make their intents known to others. According to a general principle of development, new forms then take over old functions, so that children learn words to e ...

Infant
In common terminology, a baby is the very young offspring of adult human beings, while infant (from the Latin word ''infans'', meaning 'baby' or 'child') is a formal or specialised synonym. The terms may also be used to refer to juveniles of other organisms. A newborn is, in colloquial use, a baby who is only hours, days, or weeks old; while in medical contexts, a newborn or neonate (from Latin, ''neonatus'', newborn) is an infant in the first 28 days after birth (the term applies to premature, full term, and postmature infants). Infants born prior to 37 weeks of gestation are called "premature", those born between 39 and 40 weeks are "full term", those born through 41 weeks are "late term", and anything beyond 42 weeks is considered "post term". Before birth, the offspring is called a fetus. The term ''infant'' is typically applied to very young children under one year of age; however, definitions may vary and may include children up to two years of age. When a human chi ...

Reduplication
In linguistics, reduplication is a Morphology (linguistics), morphological process in which the Root (linguistics), root or Stem (linguistics), stem of a word, part of that, or the whole word is repeated exactly or with a slight change. The classic observation on the semantics of reduplication is Edward Sapir, Edward Sapir's: "Generally employed, with self-evident symbolism, to indicate such concepts as distribution, plurality, repetition, customary activity, increase of size, added intensity, continuance." It is used in inflections to convey a grammatical function, such as plurality or intensification, and in Lexicon, lexical Derivation (linguistics), derivation to create new words. It is often used when a speaker adopts a tone more expressive or figurative than ordinary speech and is also often, but not exclusively, Iconicity, iconic in meaning. It is found in a wide range of languages and language groups, though its level of Productivity (linguistics), linguistic productivit ...

Child Development Stages
Child development stages are the theoretical milestones of child development, some of which are asserted in Psychological nativism, nativist theories. This article discusses the most widely accepted developmental stages in children. There exists a wide variation in terms of what is considered "normal", caused by variations in genetic, cognitive, physical, family, cultural, nutritional, educational, and environmental factors. Many children reach some or most of these milestones at different times from the norm. Holistic development sees the child in the round, as a whole person – physically, emotionally, intellectually, socially, morally, culturally and spiritually. Learning about child development involves studying patterns of growth and development, from which guidelines for 'normal' development are construed. Developmental norms are sometimes called milestones – they define the recognized development pattern that children are expected to follow. Each child develops in ...

Child Development
Child development involves the Human development (biology), biological, psychological and emotional changes that occur in human beings between birth and the conclusion of adolescence. It is—particularly from birth to five years— a foundation for a prosperous and sustainable society.Center on the Developing Child (2007). The Science of Early Childhood Development (InBrief). Retrieved from www.developingchild.harvard.edu. Childhood is divided into three stages of life which include early childhood, middle childhood, and late childhood (preadolescence). Early childhood typically ranges from infancy to the age of 6 years old. Early childhood development, During this period, development is significant, as many of life's milestones happen during this time period such as first words, learning to crawl, and learning to walk. Middle childhood/preadolescence or ages 6–12 universally mark a distinctive period between major developmental transition points. Adolescence is the stage of l ...

Language Acquisition
Language acquisition is the process by which humans acquire the capacity to perceive and comprehend language. In other words, it is how human beings gain the ability to be aware of language, to understand it, and to produce and use words and sentence (linguistics), sentences to communicate. Language acquisition involves structures, rules, and representation. The capacity to successfully use language requires human beings to acquire a range of tools, including phonology, morphology (linguistics), morphology, syntax, semantics, and an extensive vocabulary. Language can be vocalized as in speech, or manual as in sign language, sign. Human language capacity is language processing in the brain, represented in the brain. Even though human language capacity is finite, one can say and understand an infinite number of sentences, which is based on a syntactic principle called recursion. Evidence suggests that every individual has three recursive Mechanisms of mindfulness meditation, mech ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Speech Production
Speech production is the process by which thoughts are translated into speech. This includes the selection of words, the organization of relevant Grammar, grammatical forms, and then the articulation of the resulting sounds by the motor system using the vocal apparatus. Speech production can be spontaneous such as when a person creates the words of a conversation, reactive such as when they name a picture or reading (process), read aloud a writing, written word, or imitative, such as in speech repetition. Speech production is not the same as language production since language can also be produced manually by sign language, signs. In ordinary fluent conversation people pronounce roughly four syllables, ten or twelve phonemes and two to three words out of their vocabulary (that can contain 10 to 100 thousand words) each second. Errors in speech production are relatively rare occurring at a rate of about once in every 900 words in spontaneous speech. Words that are Frequency list, com ...

Language
Language is a structured system of communication that consists of grammar and vocabulary. It is the primary means by which humans convey meaning, both in spoken and signed language, signed forms, and may also be conveyed through writing system, writing. Human language is characterized by its cultural and historical diversity, with significant variations observed between cultures and across time. Human languages possess the properties of Productivity (linguistics), productivity and Displacement (linguistics), displacement, which enable the creation of an infinite number of sentences, and the ability to refer to objects, events, and ideas that are not immediately present in the discourse. The use of human language relies on social convention and is acquired through learning. Estimates of the number of human languages in the world vary between and . Precise estimates depend on an arbitrary distinction (dichotomy) established between languages and dialects. Natural languages are ...
