Abstract

The present electrophysiological study investigated irregular versus regular verb form processing in Swedish during reading. In line with previous results from other languages, overregularized verbs, i.e. incorrect irregular stem + regular past tense suffix combinations (e.g. * stjäl + de 'steal + past tense'), elicited a left-lateralized negativity (LAN) relative to correct irregulars (stal 'stole'), suggesting rule-based decomposition of regularly inflected words. Lack of a similar effect for misapplication of the irregular stem formation pattern on regular verbs (e.g. * löft 'lifted' instead of lyfte) suggests the involvement of different processing mechanisms, possibly whole word access, for irregular items, at least to some degree. A P600 showing reprocessing was seen for all incorrect forms. The results add cross-linguistic support for morphological decomposition in the verbal inflection of a language where results from previous neurolinguistic studies of nominal inflection have only suggested the use of full-form access to words. • ERPs of both overregularized and irregularized verbs in Swedish were recorded. • LAN obtained for overregularized verbs suggests rule-based decomposition. • Irregularized verbs elicited only a P600 relative to the correct variant.

Abstract

Most studies on spontaneous speech of individuals with agrammatism have focused almost exclusively on monolingual individuals. There is hardly any previous research on bilinguals, especially of structurally different languages; and none on characterization of agrammatism in Swahili. The current study identifies the features of Swahili agrammatic narrative and spontaneous speech, and compares the use of verb inflections for tense and time reference in English and Swahili in six bilingual agrammatic speakers and 12 non-brain-damaged speakers matched on age, native language and education level to the agrammatic speakers. The results show a remarkable similarity between the agrammatic phenomena in both languages on the typical agrammatic features: utterance length and speech rate are reduced and the proportion of grammatical sentences and complex sentences is lower than normal. Analysis of verb inflection demonstrates that there are no qualitative differences between the Swahili and English samples: in both languages reference to the past is more impaired than reference to the present. However, the use of verb inflection in general is better preserved in Swahili than English. English verb inflections are frequently omitted, whereas Swahili verb inflections are substituted.The implications of these findings for theories on agrammatism are discussed. (C) 2012 Elsevier Ltd.
