  abstract  = {Recently, neurolinguistic explanations informed by linguistic theory have been proposed to account for spontaneous and elicited agrammatic speech production. These are either formulated in terms of impaired representations or they refer to impaired processing. Both have in common that they assume severe disorders of question production due to vulnerability of the left periphery of sentence structures in the representational account, of verb movement in the processing account. We report the results of question elicitation and spontaneous speech analysis in eight chronic German agrammatic speakers. The results indicate that there is not one homogeneous agrammatic pattern, but that the data reveal double dissociations which cannot be accounted for by the unitary explanations of agrammatism which are presently available. An alternative explanation will be provided which-in contrast to the representational account not only refers to global hierarchically organized nodes but relies on linguistic differences within these nodes. The assumption that they can be differentially affected in agrammatism can account for the observed patterns. (c) 2005 Elsevier Ltd. All rights reserved},

  title     = {Passives in agrammatic sentence comprehension : a German Study},
  year      = {2004},
  abstract  = {Background: A large number of studies examining agrammatic comprehension of canonical and non-canonical sentences in Broca's aphasia have focused on passives and results have been interpreted in theoretical frameworks such as the trace deletion hypothesis (TDH: Grodzinsky, 1995a). However, there are a number of unresolved issues associated with passives. The linguistic analysis of passive structures in different languages has remained controversial as well as the empirical neurolinguistic basis of agrammatic passive comprehension. In addition, a variety of morphological and semantic questions have been raised with respect to the implicit argument in short passives and the ordering of thematic roles reflected by different positions of the by-phrase in long passives. Aims: The major aims of the present study were to re-examine the analyses of passives with and without traces, the role of an implicit argument in short passives, and the influence of the position of the by-phrase on agrammatic sentence comprehension. Methods \& Procedures: A binary picture-sentence matching task was administered to six non-fluent German agrammatic speakers. Various types of passives including long, short, and topicalised passives were tested. Additionally, comprehension of active SVO sentences was assessed in a separate but similar session. Only those patients whose comprehension on active sentences was above chance were included. Outcomes \& Results: As a group, the six subjects performed above chance over all passive types. If only long canonical passives are considered, as is done in most studies, five subjects showed a pattern compatible with the TDH. However, the picture was modified if other passive constructions were taken into account, in which case only three of the six subjects showed TDH conformity. Conclusions: There is no unique pattern of agrammatic passive comprehension and only half of the agrammatic subjects conformed to the trace deletion hypothesis. Given the results on long canonical and topicalised passives, our data support linguistic analyses that assume a trace- based derivation of passives. Furthermore, the results are in line with linguistic analyses adopting an implicit argument in short passives. Since comprehension of topicalised passives with a canonical order of theta-roles was not better than that of long passives without a canonical order, the agrammatic problem with passives does not seem to hinge on semantics},

Black-and-white line drawings were used as targets, which were overtly named by the participants. Their naming latencies were measured. In both experiments, primes consisted of past participle verbs (er tanzt/er hat getanzt "he dances/he has danced") and the relationship between primes and targets was either morphological or unrelated. Experiment 1 additionally had phonologically and semantically related prime-target pairs as well as present tense primes. Both in Experiment 1 and 2, participants showed significantly faster naming latencies for morphologically related targets relative to the unrelated verb primes. In Experiment 1, no priming effects were observed in phonologically and semantically related control conditions. In addition, the production latencies were not influenced by verb type.},

  abstract  = {Agrammatic speakers of languages with overt grammatical case show impaired use of the morphological cues to establish theta-role relations in sentences presented in non-canonical word orders. We analysed the effect of word order on the sentence comprehension of aphasic speakers of Basque, an ergative, free word order and head-final (SOV) language. Ergative languages such as Basque establish a one-to-one mapping of the thematic role and the case marker. We collected behavioural and gaze-fixation data while agrammatic speakers performed a picture-matching task with auditorily presented sentences with different word orders. We found that people with aphasia (PWA) had difficulties in assigning theta-roles in Theme-Agent order. This result is in line with processing accounts. Contrary to previous findings, our data do not suggest a systematic delay in the integration of morphological information in the PWA group, but strong reliance on the ergative case morphology and difficulties assigning thematic roles into the determiner phrases.},
