Maximal oppositions pairs one sound that is known and one sound that is unknown or two unknown sounds with the two pairs having 'maximally' different features (place, manner and voicing).
Children with mild to severe SSD who have consistent phonological errors and are missing 6 or more phonemes in their speech sound inventory.
You contrast known and unknown sounds that differ by multiple features (place, manner, voicing). You can target a known sound with an unknown sound or two unknown sounds (empty set). Start with 5 contrastive word pairs with pictures.
You present the pairs of cards and provide a model. The child needs to produce targets with 90% accuracy over 2 consecutive sessions to move to the next phase.
Present the same word pairs and have the child produce the targets without a model. The child needs to produce the targets with 90% accuracy over 2 consecutive sessions to move to the next phase.
The generalization probe is readministered and five new picture word pairs are chosen. The pattern continues until all 16 word initial sounds are mastered. Follow-up with a conversational sample 1 week after completing treatment.
