APD: What exactly are we measuring here?

Cognition, language, and physiological measures, to name a few. This review article (of 48 studies) revealed incredibly diverse diagnostic criteria and characteristics of auditory processing disorders (APD). The children in the studies with suspected APD “scored lower on language and communication scales; experienced attention and memory difficulties; and achieved lower scores on tests of NV-IQ, language, and reading.” The authors use this evidence (and more) to conclude that APD may not be a distinct clinical disorder, and instead is simply capturing characteristics of other disordersMany other studies have pointed toward this conclusion, but this one is nice in that it’s large-scale and thorough.
