Comparative Markedness and Induced Opacity
Dinnsen, Daniel A.,Gierut, Judith A.,Farris-Trimble, Ashley W. 서울대학교 언어교육원 (구 서울대학교 어학연구소) 2010 語學硏究 Vol.46 No.1
Results are reported from a descriptive and experimental study that was intended to evaluate comparative markedness (McCarthy 2002, 2003) as an amendment to optimality theory. Two children (aged 4;3 and 4;11) with strikingly similar, delayed phonologies presented with two independent, interacting error patterns of special interest, i.e., Deaffrication ([t□n] 'chin') and Consonant Harmony ([g□g] 'dog') in a feeding interaction ([kik] 'cheek'). Both children were enrolled in a counterbalanced treatment study employing a multiple base-line single-subject experimental design, which was intended to induce a grandfather effect in one case ([d□g] 'dog' and [kik] 'cheek') and a counterfeeding interaction in the other ([g□g] 'dog' and [tik] 'cheek'). The results were largely supportive of comparative markedness, although some anomalies were observed. The clinical implications of these results are also explored.
On the nature of alternations in phonological acquisition
Daniel Dinnsen,Laura McGarrity 한국음운론학회 2004 음성·음운·형태론 연구 Vol.10 No.1
This paper brings first-language acquisition evidence to bear on a guiding principle of phonology, namely the Alternation Condition, and identifies some problems with its integration into both rule-based and constraint-based theories of phonology. It has long been held that neutralization rules apply only in derived environments and that no phonological rule can apply exclusively in a nonderived environment. Three problematic case studies are considered. In the first of these, a process is shown to apply exclusively in a nonderived environment. The second case involves a different process that is also restricted to a nonderived environ-ment but requires an extended notion of what constitutes a (non)derived environment. The third case finds the same process to be restricted to a derived environment, but again requires the extended interpretation of (non)derived environments. Optimality theoretic accounts of these phenomena are formulated to take advantage of developmental changes in morphology and constraint rankings.
