2. The next step is to decide which of the key terms to include in your initial search strategy.

a. For question 1, you might use phonological, treatment, child, and disorder. Using a specific treatment approach like minimal pair might narrow the search too much, as would including a specific age group.

The term speech production overlaps with phonological, so you could just use the term disorder.

b. For question 2, you might use early detection, hearing loss, language.

The term child overlaps with early detection, and amplification overlaps with hearing loss. You could consider adding the term longitudinal because you are looking for follow-up studies.
