The processing cost of verbal and adjectival passives is investigated. Additionally, the processing cost of agentive and non-agentive PPs is contrasted in verbal passives. Inanimate subject DPs were used in irreversible sentences. The aim of this paper is to verify the extent to which processing cost can be dissociated from factors such as animacy and reversibility, which are suggestive of the strategic attribution of the agent-role to the subject DP. The results indicate that verbal passives are more costly than the adjectival ones, and that non-agentive PPs are particularly costly. A procedural characterization of the computation of these structures is suggested, in the light of the sketch of a minimalist based on-line model of syntactic computation. linguística, particularmente no contexto gerativista. Uma das questões mais controversas diz respeito à existência e à natureza do custo que passivas impõem ao processamento (FERREIRA, 2003). O presente trabalho visa a investigar, portanto, a existência e a natureza desse aparente custo de processamento na compreensão de passivas verbais em sentenças cujo sujeito é um constituinte nominal (doravante, DP) inanimado (por exemplo, o copo foi quebrado) em contraste com sentenças passivas adjetivais (por exemplo, o copo está quebrado).
Tis paper focuses the distinction between verbal and adjectival passive sentences. For that differentiation to be accounted for, a previous proposal considering a specifc functional node for eventive passives - passiveP (LIMA JÚNIOR; AUGUSTO, 2015) is retrieved. It is arguably assumed that the approach based on passiveP, besides maintaining a uniform analysis to active and passive sentences (as VoiceP in Collins (2005)), deals well with intervention issues, and is prosperous in addressing parametric variation and language acquisition facts. As far as the tripartite distinction among the different types of passives is concerned (EMBICK, 2004; DUARTE; OLIVEIRA, 2010), it is proposed that a main bipartite distinction between eventive and adjectival passives may be retained, which is here attributed to the presence of passiveP. Concerning stative and resultative passives, an agreement operation between the auxiliary verbs and the participle (LUNGUINHO, 2011) is assumed to allow for different readings to be obtained. A fourth group of passive-like sentences, involving participles, which have lost their connection with their original verbs, is also syntactically distinguished and treated as actual copular constructions.
