“…More recent studies investigating the nature of regular and irregular inflection have indeed found similar findings which do not support either the IA or the DP model (Balaguer et al, 2004;Desai et al, 2006). Of particular interest to the current study are cross-linguistic differences that appear because of the linguistic characteristics of the language.…”

“…Of particular interest to the current study are cross-linguistic differences that appear because of the linguistic characteristics of the language. Recently, De Diego Balaguer et al (2004) have suggested that differences between regular and irregular inflectional morphology can be traced to differences in the linguistic similarity of two languages. De Diego Balaguer et al (2004) found that two Catalan-Spanish bilinguals with agrammatism had similar deficits of regular morphology.…”

Age of acquisition modulates neural activity for both regular and irregular syntactic functions

Studies have found that neural activity is greater for irregular grammatical items than regular items. Findings with monolingual Spanish speakers have revealed a similar effect when making gender decisions for visually presented nouns. The current study extended previous studies by looking at the role of regularity in modulating differences in groups that differ in the age of acquisition of a language. Early and late learners of Spanish matched on measures of language proficiency were asked to make gender decisions to regular (-o for masculine and -a for feminine) and irregular items (which can end in e,l,n,r,s,t and z). Results revealed increased activity in left BA 44 for irregular compared to regular items in separate comparisons for both early and late learners. In addition, within group-comparisons revealed that neural activity for irregulars extended into left BA 47 for late learners and into left BA 6 for early learners. Direct comparisons between-groups revealed increased activity in left BA 44/45 for irregular items indicating the need for more extensive syntactic processing in late learners. The results revealed that processing of irregular grammatical gender leads to increased activity in left BA 44 and adjacent areas in the left IFG regardless of when a language is learned. Furthermore, these findings suggest differential recruitment of brain areas associated with grammatical processing in late learners. The results are discussed with regard to a model which considers L2 learning as emerging from the competitive interplay between two languages.

“…For example in Spanish, irregular verbs have identifiable affixes as well as two stems: a regular stem that is used in the infinitive and an irregular stem. There seems to be no obvious principle that predicts which verb form requires the irregular stem (Balaguer et al, 2004). Hence, lexical entries of irregular verbs represent idiosyncratic stem change information as well as a non-default affix.…”

“…This account makes two predictions: a dissociation between regular and irregular inflections with worse performance on regular inflections, and a predominant error pattern of affix omissions, resulting in verb stems. Previous investigations of regularity in agrammatic aphasia have yielded mixed results: worse performance on irregulars (Balaguer, Costa, Sebastian-Galles, Juncadella, & Caramazza, 2004;Penke, Janssen, & Krause, 1999), worse performance on regulars (Ullman et al, 1997), as well as no differences between regulars and irregulars (Bird, Lambon Ralph, Seidenberg, McClelland, & Patterson, 2003). Although some of these differences have been attributed to differences in stimuli and languages studied, the role of morphological complexity in the production of finite verbs in agrammatism needs further investigation.…”

Verb inflections in agrammatic aphasia: Encoding of tense features☆

Across most languages, verbs produced by agrammatic aphasic individuals are frequently marked by syntactically and semantically inappropriate inflectional affixes, such as Last night, I walking home. As per language production models, verb inflection errors in English agrammatism could arise from three potential sources: encoding the verbs' morphology based on temporal information at the conceptual level, accessing syntactic well-formedness constraints of verbal morphology, and encoding morphophonological form. We investigate these aspects of encoding verb inflections in agrammatic aphasia. Using three sentence completion experiments, it was demonstrated that production of verb inflections was impaired whenever temporal reference was involved; while morphological complexity and syntactic constraints were less likely to be the source of verb inflection errors in agrammatism. These findings are discussed in relation to current language production models. KeywordsMorphology; Broca's aphasia; Language; Verb; Inflection; Models of sentence production Aphasia is an impairment in producing and/or comprehending language resulting from acute brain injury such as a cerebrovascular accident. Agrammatic speech is commonly associated with the clinical syndrome of Broca's aphasia, and is frequently characterized by ill-formed sentences, reduced syntactic complexity, a paucity of verbs, and grammatical morpheme errors. Production of both free grammatical morphemes and inflectional morphemes can be impaired in agrammatic aphasia. Across most languages that have been studied, verbs produced by agrammatic aphasic individuals are frequently marked by syntactically and semantically inappropriate inflectional affixes in a variety of tasks including spontaneous speech,
