Erin F. is a 4 year, 3 month old female that has a moderate-severe phonological disorder. She has received speech and language services at MUSHC since September Beginning in the spring semester of 2013 a maximal opposition approach was selected for Erin and has continued to this day. Minimal progress with this approach has occurred over this timeframe.

For preschool aged children with phonological processes does maximal opposition or multiple opposition have a greater effect on suppressing phonological processes?

Each study found maximal opposition and multiple opposition to be successful in select ways. In regards to maximal opposition, my investigation found it was effective in changing and improving the phonological system. Further research determined maximal opposition lead to greater improvement in production of treated sounds, more additions of untreated sounds and fewer changes in known sounds. Additionally, multiple opposition was found to be valuable in the increase of both the phonetic and phonemic inventories. As well the inquiry found multiple opposition to be most effective in a more intense frequency (3 times a week). Lastly in the study that compared both approaches, all approaches were effective in the treatment of phonological disorders however, multiple opposition most favored the acquisition in the phonological system. Whereas, maximal opposition acquired a great number of sound the phonetic inventory.

Only one study compared both maximal and multiple opposition Many studies required payment to access Searched many databases without success Some studies outside the United States

Research shows both maximal opposition and multiple opposition are effective in suppressing phonological disorders. In the study comparing both approaches, Multiple Opposition had the best performance in the acquisition of sounds in the phonological system.

Maximal opposition and multiple opposition should both be taken into consideration when deciding on an approach, seeing as there is limited research that determines the more efficient intervention. When determining an approach keep the clients individual characteristics in mind. It should be noted that further research must be conducted comparing the different interventions used for treating phonological disorders.
