<P>The universalist view that acquisition of phonology is guided by universal principles has been the dominant position for decades.&nbsp; More recently, an alternative view has brought into focus the relationship between developmental markedness and language-specific input frequencies.&nbsp; With entirely original chapters on non-ambient-like productions by typically and atypically developing children, and second language learners, <I>Unusual Productions in Phonology</I> delves deeply into these competing explanations to show that patterns observed do not uniquely lend themselves to one or the other explanations.&nbsp; Rather, they point towards the need for both universal markedness and statistical input considerations in any attempted explanation.</P>
