Spoken language - Wikipedia
on a wide range of historical, philological, and ethnographic sources, Goody's relationship between spoken and written language, no agreement has been. Print Awareness is an important element for young children associating writing and reading with spoken language. Understanding the symbolic nature. In this lesson we'll explore the difference between spoken and written languages. Written words leave a physical record, allowing the writer to communicate.
In some cases where training studies are not practicable or ethical our only way of testing causal theories may be to conduct longitudinal studies and evaluate alternative interpretations for putative causal links. The approach, essentially, is to show that the relationship between a potential cause e.
Ultimately, however, to provide convincing evidence for causal hypotheses, we need to conduct training studies.
If we can show in an experiment that training a particular oral language skill e. Finally, if we can measure the functioning of a hypothetical mechanism levels of phonemic awareness that is believed to be responsible for producing improvements in reading outcomes, then we can assess the extent to which changes in an outcome reading are directly proportional to changes in the intervening mechanism PA in a mediation analyses see [ 11 ].
Put simply, if an intervention produces effects via an intermediate mechanism, then variations in the effectiveness of the intervention across individuals should be proportional to variations in the changes brought about in the hypothetical mechanism if reading improves because PA has improved, then improvements in reading should vary across individuals in line with improvements in PA. Possible causal relationships between impairments of spoken and written language a Disorders of reading accuracy and fluency A necessary step towards becoming a skilled reader is the acquisition of efficient decoding skills: If we accept that dyslexia represents the lower end of a continuous distribution of decoding skills in the population, then to explain dyslexia, we need to understand the cognitive mechanisms that are causally linked to variations in decoding skills.
There is now good evidence that there are three main predictors of individual differences in the early stages of learning to decode in alphabetic languages: Arguably, most research has sought to understand the role of PA and whether it is a cause or a consequence of learning to read [ 1617 ]. Current evidence is consistent with the notion that variations in PA, and letter—sound knowledge, are two factors that have a causal influence on the development of decoding.
RAN appears likely to be another causal influence on decoding skill although here the evidence for causation is more equivocal. Evidence from studies of children at familial risk of dyslexia indicates that early in development children who go on to develop dyslexia have relatively broad oral language weaknesses that affect vocabulary knowledge and naming skills as well as phonological oral language skills [ 18 ].
Many concurrent and longitudinal studies have assessed the relationship between PA and children's reading ability.
Analyses of studies of unselected samples showed that phonemic awareness was a strong correlate of individual differences in word reading ability, and that this effect remained reliable after controlling for variations in both verbal short-term memory and awareness of the onset-rime components of words. Moderate correlations have been reported between LK assessed at the start of formal reading instruction and word reading skills measured later that year or early the next year [ 142021 ].DIFFERENCE BETWEEN ORAL AND WRITTEN
In different studies, LK has been assessed using measures of either letter—sound knowledge, letter—name knowledge or both. These two measures are typically moderately correlated with each other.
Theoretically, however, it is letter—sound knowledge which is likely to be a critical determinant of variations in children's ability to learn to read, because it is one of the foundations of the alphabetic principle [ 22 ].

Both these effects operate longitudinally from an age when reading skills are very limited [ 1421 ] suggesting that they may reflect causal influences on learning to read. Direct evidence for causation requires training studies.
Differences between writing and speech
There is evidence that training phonemic awareness in children is effective in helping to improve word reading skills, especially when such training is coupled with appropriate phonically based reading instruction.
Context and shared knowledge play a major role, so it is possible to leave much unsaid or indirectly implied. Writers can make use of punctuation, headings, layout, colours and other graphical effects in their written texts.
Such things are not available in speech Speech can use timing, tone, volume, and timbre to add emotional context. Written material can be read repeatedly and closely analysed, and notes can be made on the writing surface.
The interface between spoken and written language: developmental disorders
Only recorded speech can be used in this way. Some grammatical constructions are only used in writing, as are some kinds of vocabulary, such as some complex chemical and legal terms.
Some types of vocabulary are used only or mainly in speech. A spoken language is a language produced by articulate sounds, as opposed to a written language.
Many languages have no written form and so are only spoken. An oral language or vocal language is a language produced with the vocal tract, as opposed to a sign languagewhich is produced with the hands and face. The term "spoken language" is sometimes used to mean only vocal languages, especially by linguists, making all three terms synonyms by excluding sign languages.
Others refer to sign language as "spoken", especially in contrast to written transcriptions of signs.
That contrasts with written language in which more of the meaning is provided directly by the text. In spoken language, the truth of a proposition is determined by common-sense reference to experience, but in written language, a greater emphasis is placed on logical and coherent argument. Similarly, spoken language tends to convey subjective information, including the relationship between the speaker and the audience, whereas written language tends to convey objective information.
