ABSTRACT
The next two most popular tests are two oral reading tests: Nonwords [24] & Imageability×Frequency [31]. A further oral reading test of word regularity [35] also scores highly and, between them, these three tests account for 11% of all reported instances of PALPA test use. As we mentioned earlier, it seems likely that these tests
feature prominently because of their use in differentiating different kinds of acquired dyslexic disorder. It is also worth noting in this context that the fifth test in the list is the auditory lexical decision version [5] of the Imageability×Frequency reading aloud test [31]. Along with the written lexical decision version [25], ninth in the list, these tasks have clearly showed their worth in exploring impairments that may be frequency and/or imageability dependent within and across modality.
