Studies have found that in children ages 4–6 there is less disturbance of speech than in children ages 7–9 under a delay of 200 ms. Younger children are maximally disrupted around 500 ms while older children around 400 ms. A 200 ms delay produces maximum disruption for adults.
Research has shown that in children aged 4–6, speech is less disrupted than in children aged 7–9 by a delay of 200 milliseconds. Younger children experience maximum disruption around 500 milliseconds while older children around 400 milliseconds. A 200 millisecond delay results in the most disruption for adults.
