Symptoms / Characteristics: 
- groping

Symptoms / Charateristics: 
- by age 3 at least half of what a child says should be intelligible
- by age 5 most of what a child says should be intelligible 
- more difficult sounds may not be completely correct until age 7 or 8 
- speech is used to modify word and sentence meaning 
- contributes to social and academic success
- sound development based on typical milestones as shown in the chart below

- negatively affects the intelligibility of an individual
- prevalence slightly higher in males than females

How are they different?
CAS only occurs in children. 
Phonological Disorders can occur at any age. 

CAS is characterized by inconsistent speech errors. 
Phonological Disorders are characterized by consistent speech errors.

A child with CAS cannot produce an accurate plan for physical movement of articulators to produce speech. 
An individual with a phonological disorder is unaware of phonological rules used to produce appropriate speech. ]]> 2017-09-26 13:31:47 UTC https://padlet.com/lauebake/lvo2ncdyzs9k/wish/191234659 lauebake https://padlet.com/lauebake/lvo2ncdyzs9k/wish/191342704 2017-09-26 16:26:53 UTC https://padlet.com/lauebake/lvo2ncdyzs9k/wish/191342704 lauebake https://padlet.com/lauebake/lvo2ncdyzs9k/wish/191352622 2017-09-26 16:45:08 UTC https://padlet.com/lauebake/lvo2ncdyzs9k/wish/191352622 lauebake https://padlet.com/lauebake/lvo2ncdyzs9k/wish/191353319 2017-09-26 16:46:12 UTC https://padlet.com/lauebake/lvo2ncdyzs9k/wish/191353319 How do Phonological Disorders, CAS, and Typical Speech Development compare? kodom31 https://padlet.com/lauebake/lvo2ncdyzs9k/wish/191483085 - involve production of speech sounds
- affect the intelligibility of an individual
- may contribute to social and academic abilities
- errors are not caused by muscle weakness or paralysis

How are the three different?
- CAS often affects rate, rhythm, and stress while Phonological Disorders and Typical Speech Development do not affect these aspects of communication. 
- CAS involves difficulty of motor planning for speech while Phonological Disorders and Typical Speech do not have an impact on motor planning. ]]> 2017-09-26 22:57:52 UTC https://padlet.com/lauebake/lvo2ncdyzs9k/wish/191483085
