“…Moreover, several recent studies have found production of elements associated with CP to be more impaired than production of elements associated with lower functional projections. This selective impairment of CP has been observed in Japanese (Hagiwara, 1995); Hebrew, Palestinian Arabic, and English (Friedmann, 2001;Friedmann, 2002); German (Burchert, Swoboda-Moll, De Bleser, 2005b) and Greek (Stavrakaki & Kouvava, 2003). Consistent with the tree structure proposed by Pollock (1989), in which IP is `split' further into separate tense and agreement nodes, the Tree Pruning Hypothesis (TPH) has also proposed that verb morphology associated with tense should be more impaired than morphology associated with agreement.…”

Hierarchical models of agrammatism propose that sentence production deficits can be accounted for in terms of clausal syntactic structure (Friedmann & Grodzinsky, 1997;Hagiwara, 1995). Such theories predict that morpho-syntactic elements associated with higher nodes in the syntactic tree (complementizers and verb inflections) will be more impaired than elements associated with lower structural positions (negation markers and aspectual verb forms). While this hypothesis has been supported by the results of several studies (Benedet, Christiansen, & Goodglass, 1998;Friedmann, 2001Friedmann, , 2002, it has also been challenged on several grounds (Burchert, Swoboda-Moll, & De Bleser, 2005a;Lee, 2003;Lee, Milman, & Thompson, 2005). In this paper the question of hierarchical structure was re-examined within the framework of Item Response Theory (IRT, Rasch, 1980). IRT is a probabilistic model widely used in the field of psychometrics to model behavioral constructs as numeric variables. In this study we examined production of functional categories (complementizers, verb inflections, negation markers, and aspectual verb forms) in narrative samples elicited from 18 individuals diagnosed with nonfluent aphasia and 18 matched controls. Data from the aphasic participants were entered into an IRT analysis to test 1) whether production of clausal functional categories can be represented as a variable on a numeric scale; and 2) whether production patterns were consistent with hierarchical syntactic structure. Pearson r correlation coefficients were also computed to determine whether there was a relation between functional category production and other indices of language performance. Results indicate that functional category production can be modeled as a numeric variable using IRT. Furthermore, although variability was observed across individuals, consistent patterns were evident when the data were interpreted within a probabilistic framework. Although functional category production was moderately correlated with a second measure of clausal structure (clause length) it was not correlated with more distant language constructs (noun/verb ratio and WAB A.Q.). These results suggest that functional category production is related to some, but not all, measures of agrammatic language performance.

“…Second, the syntactic difference between wh-questions and yes/no-questions, as, despite the fact that in both question types there is an operator under the Spec, CP, they differ as to the movement of the operator: in wh-questions an operator moves from its base-generated position to the Spec, CP, whereas in yes/noquestions no movement occurs, since an empty operator is directly generated under the Spec, CP. On the basis of these facts, Burchert et al (2005) formulated two hypotheses: the Operator Movement Hypothesis and the Empty Category Deletion Hypothesis. According to the former, some agrammatic speakers have difficulty moving the operator, which affects wh-questions.…”

“…Os dados de fala espontânea do Holandês e do Alemão (Kolk e Heeschen 1992, de Roo 2001, Bastiaanse e van Zonneveld 1998, Burchert et al 2005 indicam que quando um verbo flexionado é produzido, ele aparece na segunda posição da sentença, ou seja, movido de sua posição de origem, que é a final. Dados de teste com falantes do Alemão (Wenzlaff e Clahsen 2005) e do Holandês (Kok et al 2006) apontam para o mesmo padrão.…”

Este artigo apresenta resultados de um estudo de rastreamento ocular de frases contendo sintagmas preposicionais (SP) com função de adjunto ou de argumento de um verbo, que admitem aposição sintática ambígua ao sintagma verbal ou ao sintagma nominal objeto. Os resultados obtidos indicam que o processador sintático não faz uso imediato da informação lexical relativa ao estatuto do SP como adjunto ou argumento, acessando esta informação apenas na fase de reanálise, após a recuperação do efeito labirinto (garden-path).
