“…The present research adds into a long series of studies, which show that behavioral data of healthy adults and of brain-damaged patients can dissociate the language faculty into two components. First, our results suggest that lexical mechanisms apply to monomorphemic representations such as irregular forms and roots, whereas combinatorial rules apply to complex words such as regular or subregular forms (see also Clahsen et al, 1997;Schreuder & Baayen, 1995;Taft, 1979). Second, we showed that both language components can be dissociated in striatal-damaged patients.…”

“…One such manipulation is the word frequency effect by which rule-defined decomposition of suffixed words has been related to automatic processing within the language module (see e.g., Taft, 1979). Clahsen, Eisenbeiss, and Sonnenstuhl (1997), using a lexical decision task (word vs. nonword decision), have shown that reaction times (RTs) with irregular verbs depend on form frequency, reflecting that conjugated forms of irregulars are accessed in the mental lexicon, whereas RT with regulars do not. Conversely, it has been shown that RTs with regular verb forms depend on the frequency of their root, reflecting that roots of regulars (and not conjugated forms) are accessed in the mental lexicon and that morphemic decomposition is primarily involved (Bertram et al, 2000).…”

On the assumption that linguistic faculties reflect both lexical storage in the temporal cortex and combinatorial rules in the striatal circuits, several authors have shown that striatal-damaged patients are impaired with conjugation rules while retaining lexical knowledge of irregular verbs [Teichmann, M., Dupoux, E., Kouider, S., Brugières, P., Boissé, M. F., Baudic, S., Cesaro, P., Peschanski, M., & Bachoud-Lévi, A. C. (2005). The role of the striatum in rule application. The model of Huntington's disease at early stage. Brain, 128, 1155–1167; Ullman, M. T., Corkin, S., Coppola, M., Hickok, G., Growdon, J. H., Koroshetz, W. J., & Pinker, S. (1997). A neural dissociation within language: Evidence that the mental dictionary is part of declarative memory, and that grammatical rules are processed by the procedural system. Journal of Cognitive Neuroscience, 9, 266–276]. Yet, such impairment was documented only with explicit conjugation tasks in the production domain. Little is known about whether it generalizes to other language modalities such as perception and whether it refers to implicit language processing or rather to intentional rule operations through executive functions. We investigated these issues by assessing perceptive processing of conjugated verb forms in a model of striatal dysfunction, namely, in Huntington's Disease (HD) at early stages. Rule application and lexical processes were evaluated in an explicit task (acceptability judgments on verb and nonword forms) and in an implicit task (lexical decision on frequency-manipulated verb forms). HD patients were also assessed in executive functions, and striatal atrophy was evaluated with magnetic resonance imaging (bicaudate ratio). Results from both tasks showed that HD patients were selectively impaired for rule application but lexical abilities were spared. Bicaudate ratios correlated with rule scores on both tasks, whereas executive parameters only correlated with scores on the explicit task. We argue that the striatum has a core function in linguistic rule application generalizing to perceptive aspects of morphological operations and pertaining to implicit language processes. In addition, we suggest that the striatum may enclose computational circuits that underpin explicit manipulation of regularities.

“…A third approach is offered by the so-called Dual Mechanism model (e.g., Pinker & Prince, 1994;Clahsen et al, 1997;Clahsen, 1999;Sonnenstuhl et al, 1999). Here, the linguistic distinction between irregular and default inflection is claimed to determine how complex word forms are represented and processed.…”

“…These findings suggest that speakers of English activate a computational mechanism to process regular forms (by concatenating a base to a suffix: walk + ed in language production or decomposing the items into their morphological constituents in language comprehension), but rely on memory to process irregular forms. Research on languages other than English has shown a similar pattern (BOWDEN, 2007;MORGAN-SHORT et al, 2010;EISENBEISS;SONNENSTUHL, 1997). Other findings, however, contradict such claims.…”

Este artigo apresenta um estudo comportamental que teve como objetivo investigar se substantivos inanimados do português do Brasil, transparentes quanto ao seu gênero gramatical (substantivos femininos terminados em -a e masculinos terminados em -o) e opacos (outras terminações) são ou não processados por mecanismos cognitivos distintos. Para tanto, uma tarefa de concordância de gênero foi executada por 19 sujeitos em duas condições: entre um artigo definido e um substantivo (condição 1) e entre um substantivo e um adjetivo (condição 2). Fatores como a frequência dos substantivos e adjetivos (alta vs. baixa) e forma fonológica (transparente vs. opaca) foram manipulados. Os resultados mostram que, em ambas as condições, a frequência é um forte preditor de respostas mais rápidas, sugerindo que tanto formas transparentes quanto formas opacas podem ser armazenadas na memória. Este padrão foi encontrado em ambas as condições. Estes resultados foram interpretados como evidência para a visão unitária de processamento da linguagem.
