| This thesis investigates the question of how the arguments of a given verb are linked to positions in a phrase structure. Through a study of passives, psych verbs, and ditransitive verbs in Japanese, it provides empirical support for the hypothesis that arguments having particular thematic roles are associated with particular syntactic positions systematically.;Chapter 2 deals with passives, in particular, two types of passive constructions, direct and indirect passives. Following some previous works, it is argued that the subject of a direct passive is generated in the same position as an object of the corresponding active verb, having the same thematic role, whereas the subject of an indirect passive is projected as an argument of a separate predicate. Several pieces of evidence for this hypothesis which are not given in the literature are provided here.;Chapter 3 is concerned with psych verbs, focusing on those that participate in a causative alternation. It is proposed that causative counterparts of these verbs can have two different structures that are parallel to the two types of passives discussed in Chapter 2. The subject of one type is generated in the same position as the object of the noncausative counterpart, having the same thematic role, whereas the subject of the other type is projected as an argument of a separate predicate.;Chapter 4 takes up ditransitive verbs, specifically, those that have inchoative counterparts, which do not project the subject of the ditransitive construction. There are two types of such verbs: one promotes the accusative argument of the ditransitive construction, rather than the dative one, to the subject of the inchoative counterpart, while the other chooses the dative argument over the accusative one for the subject of the inchoative counterpart. It is argued that this reflects the difference in the base-generated position of the dative argument between the two types of verbs. Moreover, the dative arguments of the two are distinguished in terms of thematic role.;This research is meant to contribute toward having a further understanding of how the participants of an event are expressed in grammatical forms. |
