본 연구는 한국어 동사의 활용된 형태인 굴절 동사의 심성어휘집 접근 과정을 알아보기 위한 연구이다. 이를 위하여 차폐 점화 어휘 판단과제 실험을 실시하여 점화크기를 비교하였다. 한국어 규칙 동사와 불규칙 동사를 다섯 가지로 나누어 실험을 수행하였다. 활용의 종류는 1) 완전규칙 2) 발음변화규칙 3) 철자변화규칙 4) 어간변화 불규칙 5) 어미변화 불규칙으로 1), 2), 3)은 규칙 활용의 범주로 4), 5)는 불규칙활용의 범주이다. 기본형의 동사를 표적자극으로 사용하였고, 점화자극으로 총 세 가지 유형이 사용하였다. 점화자극으로 사용한 자극은 기본형의 어간의 변화가 없는 규칙활용, 기본형의 어간이 철자적, 음운적으로 변화하는 불규칙활용과, 의미 및 형태적으로 관련 없는 통제된 단어이다. 또한 단어재인의 처리에서 형태소 분해 정보처리의 시간대를 살펴보기 위하여 SOA의 간격을 43ms, 72ms, 230ms의 3가지로 나누어 실험하였다. 모든 동사가 모든 SOA에서 규칙활용과 불규칙활용이 통제단어에 비해 빠른 반응시간을 보임으로써 점화효과가 관찰되었다. 그러나 규칙활용과 불규칙활용에서 뚜렷이 점화효과의 차이가 관찰되지 않는다. 이러한 규칙활용과 불규칙활용의 범주의 구분 없이 비슷한 패턴을 보여주는 결과는 한국어가 단순히 규칙과 불규칙의 기준으로 나뉘어서 처리되지 않는다는 것을 시사한다. 또한 모든 SOA에서 촉진효과를 보임으로써 형태소 정보처리가 초기과정부터 일어남을 확인하였다.

The paper is to argue against the asymmetric CP-V2 analysis of Old English, according to which finite verbs invariably undergo movement into a clause-final T within subordinate clauses and reach the functional head C within main clauses. The asymmetric CP-V2 analysis, first of all, faces difficulty in explaining a wide range of post-verbal elements within subordinate clauses. To resolve the problem, the analysis has to abandon the obligatoriness of V-to-T movement or introduce various types of extraposition whose status is dubious as a legitimate syntactic operation. Obligatory V-to-T movement in Old English lacks conceptual justification as well. Crosslinguistic evidence reveals that morphological richness in verbal inflection cannot entail overt verb movement. Moreover, the operation is always string-vacuous under the asymmetric CP- V2 analysis and has no effect at the interfaces, in violation of the principle of economy. The distribution of Old English finite verbs in main clauses also undermines the asymmetric CP-V2 analysis. Conceptually speaking, a proper syntactic trigger cannot be confirmed to motivate obligatory verb movement to C. The operation not only gets little support from nominative Case marking, the distribution of expletives, or complementizer agreement but also requires the unconvincing stipulation that expletives as well as sentence-initial subjects result from string-vacuous topicalization. Finally, textual evidence testifies that Old English sometimes permits non-V2 ordering patterns, many of which remain unexplained under the asymmetric CP-V2 analysis.

The nominative and accusative postpositions in Korean may intervene between the negative auxiliary verb ANH and its complement verb phrase. As Korean is an OV language, this means that 'verb + {nom, acc} + ANH' as well as the simpler concatenation 'verb + ANH' is possible. This fact, together with an overwhelming regularity of these postpositions' optionality in virtually all constructions, poses a problem for formal approaches to the syntax of the language. Working in a constraint-based grammatical framework shaped by such works as Sag and Wasow (1999) and Copestake (2002), we put forth type hierarchies for major_class, which represents verb inflection, and for pos, which has two immediate subtypes, i.e., htrp_pos and ord_pos. What we call the 'half transparency' of the case postpositions separates them from all the other lexical items in the language. The type htrp_pos is used to constrain one of the two newly proposed head_comp_rules, where a newly proposed feature HEAD2 of a phrase inherits its value from the HEAD feature of the head word. The COMPS list of the negative auxiliary ANH is seen as containing a single phrase whose HEAD is a kind of nominal clause and whose HEAD2 is something that is one of the three maximal types: acc, nom, and null.
