Several scholars have claimed that childhood bilingualism may enhance development of linguistic awareness. In the present investigation, metalinguistic ability is studied in terms of the dual skill components outlined by Bialystok and Ryan (1985): control of linguistic processing and analysis of linguistic knowledge. A total of 38 English–Swedish bilinguals, assigned to two groups according to relative proficiency, and 16 Swedish monolinguals, all aged 6 to 7 years, received three tasks: symbol substitution, grammaticality judgment, and grammaticality correction. Effects of general bilingualism were found on tasks requiring a high control of linguistic processing, thus replicating previous findings. The results indicated that a high degree of bilinguality may also enhance the development of linguistic analysis. Moreover, it was found that certain metalinguistic skills – especially control of processing – were more readily applied in the subjects' weaker language.

Three studies examined the sources of learning by which children, very early in learning to read, formed correspondences between letters and phonemes when these were not explicitly taught in the whole language instruction they received. There were three classes of predicted knowledge sources: (a) induced sublexical relations (i.e., induction of orthographic–phonological relations from the experience of print words), (b) acrophones from letter names, and (c) transfer from spelling experience. The results of Study 1 indicated that children used both sources (a) and (b). Study 2 results showed that source (a) dominated when the letters were initial components of pseudowords rather than isolated items. The transfer from phoneme-to-grapheme correspondences of the children's spelling was examined in Study 3. The results were not consistent with the use of source (c). The findings of these studies have implications for the question of how early in learning to read children are able to use knowledge from their experience of print words as a source for phonological recoding.

The production of regular and irregular past tense forms was investigated among the members of an English-speaking family with a hereditary disorder of language. Unlike the control subjects, the family members affected by the disorder failed to generate overregularizations (e.g., digged) or novel regular forms (plammed, crived), whereas they did produce novel irregularizations (crive–crove). They showed word frequency effects for regular past tense forms (looked) and had trouble producing regulars and irregulars (looked, dug). This pattern cannot be easily explained by deficits of articulation or of perceptual processing, by previous simulations of impairments to a single-mechanism system, or by the extended optional infinitive hypothesis. We argue that the pattern is consistent with a three-level explanation. First, we posit a grammatical deficit of rules or morphological paradigms. This may be caused by a dysfunction of a frontal/basal-ganglia “procedural memory” system previously implicated in the implicit learning and use of motor and cognitive skills. Second, in contexts requiring inflection in the normal adult grammar, the affected subjects appear to retrieve word forms as a function of their accessibility and conceptual appropriateness (“conceptual selection”). Their acquisition and use of these word forms may rely on a “declarative memory” system previously implicated in the explicit learning and use of facts and events. Third, a compensatory strategy may be at work. Some family members may have explicitly learned a strategy of adding suffix-like endings to forms retrieved by conceptual selection. The morphological errors of young normal children appear to be similar to those of the affected family members, who may have been left stranded with conceptual selection by a specific developmental arrest. The same underlying deficit may also explain the impaired subjects' difficulties with derivational morphology.

Traditional computational accounts of gender representation and learning (e.g., Carroll, 1989, 1995) differ radically from cue-based and connectionist accounts. The latter but not the former predicts that access to noun gender will vary depending on the reliability of noun endings (and other sublexical elements and morphological constituents) in marking gender, and that agreement markers can be used strategically to constrain the genders of ambiguously marked nouns. Adult native (L1) speakers of Russian (Experiment 1) and advanced nonnative (L2) speakers (Experiment 2) read Russian sentences on a computer and were asked to choose one of two inflected past tense verbs in a forced choice task. The verbs either matched or mismatched the gender of the subject NP. Half of the target trials used opaque (end-palatalized) subject nouns, which were ambiguously marked for gender, and the other half used transparent (regularly marked) subject nouns. Noun type was crossed with the presence or absence of a gender-marked adjective in the subject NP. When an adjective was present in the subject NP, both L1 and L2 speakers were significantly faster at reading and selecting the correct verb form. L2 but not L1 speakers showed longer reading and choice latencies and made more errors when the subject noun was opaque. The data showed that L2 speakers used adjective inflections to disambiguate the gender of opaque subject nouns and to select gender appropriate verb inflections. The accuracy data for L1 and L2 speakers were tested against several connectionist models. The models' success in accounting for the data suggested that L1 and L2 speakers may depend on a common learning mechanism and thus resemble one another at the computational level, contrary to traditional computational accounts (Carroll, 1989, 1995).

Reading-disabled children display a phonemic awareness deficit when compared with normally achieving children matched for word reading ability. However, previous research has not examined phonemic awareness deficits in reading-disabled children when compared with children matched on pseudoword reading. This article examines phonemic awareness ability in both a traditional design and a pseudoword reading level match design. The results show that a group of reading-disabled children who show typical pseudoword reading and phonemic awareness deficits in the traditional reading level match design nonetheless have phonemic awareness skills commensurate with their level of pseudoword reading ability.
