Hi, anakledang0616.com just want to share with all readers especially for parent with baby right now or those who will have a baby on day, insyallah.
Based of the book just RM12.90, title Learn Faster and Remember More by David Gamon Ph.D and Allen D. Bragdon.
Firstly, i would like to share on typical language development stages by age
0-1 year : Babbles; learn to recognize own name
1 year : Utters single words, such as ayah; susu, mamam.
1 1/2 years : Has active vocabulary of about 50 words; begin combine words, such as a mama masak, dah habis, sakit kaki,
2-3 years : has productive vocabulary of about 500 words at 2 1/2 years. Increase length of word combination, such as I sit down, here it comes, i watching kitty. begins to use grammatical morphemes, such as -ing, plurals, the, past tenses. begin to use negative and question forms, such as will you help me? and i don't like you
3-4 years : Starts using more complex, multi clause utterances, such as I show you how to do it, watch me sit down, i want this one because it's big
Some of the example in Bahasa Malaysia i just guessing from the English word given. But in my experience, there is such a big different on this language development based on the type of parent language, this is cause by their environment, some kids develop in the 1 based language, some mixed between 2-3 language.
This language development is just for normal active baby. Let's we see for the Specific Language Impairment (SLI) the cause of abnormal brain developments for baby
Some most commen type of SLI
1. Phonological-syntactic deficit : Children have dificult pronoincing word properly and decoding synthaz - the rules for relating words to each other in a sentence,(I like old people and cats, for instance, is syntactically ambiguous, and so can be construed in two ways.). These children have a hard time comprehending long, complex sentences, may speak very little and are hard to understand
2. Semantic-pragmatic disorder : These children don't have pronunciation problems. They have difficulty with word meanings, as well as with the more subtle rules governing the use of words in social context. An example of these latter problem would be failling to understand "Do you like peppermints?" as a possible indirect offer, or "Your room is a mess" as a possible indirect request. Autistic children and adults typically have this kind of dificulty with pragmatics.
3. Lexical-sematic deficit: This children have problems moving their vocal apparatus in the appropriate way for normal speech, making themselves very hard to understand. The london family with a genetically-based language dissorder has development dyspraxia, Their understand of language isn't effect
Most commen type of SLI due to error of genetics, on brain developments.
