Characteristics of Diadochokinesis in Typically Developing Children and Adults

Purpose: The purpose of this study was to examine the characteristics rate and perceptual judgment diadochokinesis (DDK) in typically developing children adults.Methods: Participants were aged 2;6 9;11 normal adults. For DDK tasks, they asked repeat [p*a], [t*a], [k*a], [p*at*a], [p*at*ak*a] accurately quickly with one breath. number repetitions per second measured as for each stimuli. also performed terms regularity, rate, accuracy using a three-point scale.Results: Children showed increases all tasks age. However, groups between ages 9:11 exhibited significantly slower rates than In accuracy, consistency sequential motion [p*at*a] statistically significant differences across age groups. demonstrated similar SMR adults after 6;0.Conclusion: This developmental patterns speech motor skills based on tasks. provides references assessing related difficulties.
