Phonological disorders in children have been the subject of several studies aiming to identify the optimal remedial treatment1 2 3 4 5 6 7 8. Nevertheless, before any phonological therapy can begin, the speech therapist has to carry out a wide ranging and complete phonological evaluation in order to exclude alterations (motor, neurological) that are not correlated with any phonological disorder5 6 8. In addition, it is important to have knowledge about normal phonological acquisition, that is, information regarding the phonemes that are expected to be produced correctly by children at each age and how these are organized contrastively in the language. Knowledge of normal acquisition patterns enables the therapist to evaluate evidence of abnormal acquisition and determine whether the child has a phonological disorder #RaiseAgainstAutism #PinnacleSaysItAll #PinnacleBloomsNetwork #1AutismTherapyCentresNetwork
