The revised assessment of basic language and learning skills (ABLLS-R) is an assessment tool, curriculum guide, and skills-tracking system used to help guide the instruction of language and critical learner skills for children with autism or other developmental disabilities.
At 4 months, infants still prefer infant-directed speech to adult-directed speech. Whereas 1-month-olds only exhibit this preference if the full speech signal is played to them, 4-month-old infants prefer infant-directed speech even when just the pitch contours are played. [6]
There is a relationship between children's prelinguistic phonetic skills and their lexical progress at age two: failure to develop the required phonetic skills in their prelinguistic period results in children's delay in producing words. [10]
Prelingual hearing loss can be considered congenital, present at birth, or acquired, occurring after birth before the age of one. Congenital hearing loss can be a result of maternal factors (rubella, cytomegalovirus, or herpes simplex virus, syphilis, diabetes), infections, toxicity (pharmaceutical drugs, alcohol, other drugs), asphyxia, trauma, low birth weight, prematurity, jaundice, and ...
The method in which we develop language skills is universal; however, the major debate is how the rules of syntax are acquired. [9] There are two quite separate major theories of syntactic development: an empiricist account by which children learn all syntactic rules from the linguistic input, and a nativist approach by which some principles of ...
Usually occurring by about ten months of age, the jargon stage is defined as "pre-linguistic vocalizations in which infants use adult-like stress and intonation". [17] The general structure of the syllables that they are producing is very closely related to the sounds of their native language and this form of babbling significantly predicts the ...
Gestures are distinct from manual signs in that they do not belong to a complete language system. [6] For example, pointing through the extension of a body part, especially the index finger to indicate interest in an object is a widely used gesture that is understood by many cultures [7] On the other hand, manual signs are conventionalized—they are gestures that have become a lexical element ...
Baby sign programs encourage parents to improve their communication skills between themselves and their infants before they have developed speech. [7] Kirk and colleagues have found that the results of their study with hearing infants provided no evidence to support that a child's language development would benefit from learning baby sign.
