Pictello videos training: [] iCommunicate: >"It is critical for an individual to not only have symbols, but also to have experience with those symbols in a symbol rich environment / print rich environment. The typically developing child will have been exposed to oral language for approximately 4,380 waking hours by the time he begins speaking at about 18 month of age. If someone is using a different symbol set and only has exposure to it with the speech pathologist two times a week, 20-30 minutes each, it will take the alternate symbol user 84 years to have the same experience with his symbols that the typically developing child has with the spoken word in 18 months!!! >The typically developing child will demonstrate language competency around 9-12 years of age having been immersed in and practicing oral language for approximately 36,500 waking hours. For 9-12 years that child has been using and receiving corrective feedback while practicing with the spoken word. At twice a week, 20-30 minutes each time, it will take the alternate symbol user 701 years to have the same experience with his symbols. Yup! 701 years to have commensurate experience!!!" More information:  Children from high SES are exposed to 2153 words/hour; children from more culturally challenged situations, 616 words/hour. Also, children from high SES hear more comments and fewer prohibitive language than children from lower SES. (32 comments/hour vs. 5 comments/hour; 5 negatives/hour vs 11 negatives/hour. (Cited from A. Costantino, 2011, from Hart & Risley, 1995).

Also from Costantino, in the FACES study (Family and Children Experiences Survey) Spring 1998, on a sample of 1580 children in Head Start, the frequency of reading to children by parents was the only factor correlated with increased vocabulary (Hammer, Farkas & Maczuga, 2010).
