What Is Language?
1. Arbitrariness – uses symbols that are not related to the concept that they represent (e.g.,
hieroglyphics vs. English letters)
2. Productivity – can produce communications that are unique; can express completely
novel ideas
What Is Language?
3. Semanticity – language represents a form of patterned information
4. Displacement – language is independent of time, so you can talk about past, present, and
future
5. Duality – language is represented on two levels: the sounds of the language and its
underlying meaning
Language Development
, • Language development occurs universally, and usually progresses through common
stages: crying (0-4m), cooing/babbling (4-12), initial words (12-18), two-word sentences
(18-36), short sentences (2.5-5y), adult usage (5y+)
• Also often involves body gestures that appear at an early age
Components of Language
Phonological Development
• Phonological development refers to learning the sounds of a language
• Babbling includes subset of language sounds, may serve a social function
• Babbling initially universal, then specific
• Babbling appears to to arise from the same neural structures as language (e.g., left lobe)
Atypical Language Development
• Video 1 – 203 (S.A.F.) : http://chedd-angier.com/frontiers/season2.html
• 33:30min- 44:50
• Can be impaired if there are significant delays in early learning of language
• Makes early intervention a priority (e.g., cochlear implants)
• Maturation or a lack of experience?
Phonological Development
Morphological Development
• Free morphemes stand alone, bound morphemes attach to free morph.
