This study examined the extent to which first language (L1) fluency behavior, cross-linguistic differences, and proficiency can predict second language (L2) fluency behavior over time. English L1 Spanish (n = 24) and French (n = 25) majors completed a picture-based oral narrative in the L2 before and after 5 months residing abroad and later in the L1 after returning home. Data were coded for seven measures of speed, breakdown, and repair fluency. The results from multiple regressions indicated that L1 fluency behavior, cross-linguistic differences, and proficiency differentially contributed to explaining L2 fluency behavior prior to and during immersion. These findings suggest that when investigating L1–L2 fluency relationships considerations of mitigating factors such as cross-linguistic differences are necessary, and it is worthwhile to focus on how the contributions of these factors shift during development.

The present study compares the performance of multilingual children speaking Cypriot Greek, Standard Modern Greek, and English (and sometimes an additional language), bilectal children speakers of Cypriot Greek and Standard Modern Greek, and Standard Modern Greek-speaking monolingual children on a task that measures the comprehension of different types of implicature. Despite lower scores in language ability in the target language, multilingual and bilectal children performed at rates comparable to the monolinguals with implicature. Regression analyses indicated a positive correlation between implicature, language proficiency, and age (but not executive control), albeit language ability did not affect implicature within multilinguals. We suggest an interpretation according to which multilingual, bilectal, and monolingual children maintain a comparable level of implicature understanding, but they do so by relying on different resources. Finally, a principal component analysis on different implicature types revealed a single factor of implicature performance. This outcome has implications for pragmatic theory.

In children and adults, naming an item sometimes interferes with later attempts to name other items. Adult speakers experience cumulative semantic interference, interpreted as the result of incremental learning. Studies to date have not examined whether incremental learning can also account for interference in children. This study examined context effects on picture naming in 3-year-old children, and investigated whether children, like adults, show interference that is semantically based and cumulative. Children named pictures from semantically homogeneous and mixed sets. Response latency, accuracy, and repetition errors were recorded. The results demonstrated a progressive slowing of responses in the semantically homogeneous condition that was greater than that observed for the mixed condition. There were no significant effects for accuracy. Repetition errors, although infrequent, patterned similarly to previous reports for adults. The results indicate that preschool-aged children experience cumulative semantic interference in naming, and suggest that incremental learning may account for interference effects across development.

Exposure to a minority language is largely limited in terms of frequency, and often delivered by nonnative speakers in certain domains. This study aimed to evaluate the effectiveness of two types of native-language input sources (story telling and minority language children's television) in providing 4- and 5-year-old native English-speaking children with beginning awareness of Welsh. Results revealed that exposure to Welsh via television programs was equally as beneficial, if not more so in some cases, as listening to Welsh stories in developing children's vocabulary, particularly within the context of social interaction. These results suggest a useful and potentially effective role for the use of native-language television within a carefully designed language curriculum to aid early second language development in minority language contexts.

The cumulative effects hypothesis (CEH) claims that bilingual development would be a challenge for children with specific language impairment (SLI). To date, research on second language (L2) children with SLI has been limited mainly to their early years of L2 exposure; however, examining the long-term outcomes of L2 children with SLI is essential for testing the CEH. Accordingly, the present study examined production and grammaticality judgments of English tense morphology from matched groups of L2 children with SLI and L2 children with typical development (TD) for 3 years, from ages 8 to 10 with 4–6 years of exposure to English. This study found that the longitudinal acquisition profile of the L2 children with SLI and TD was similar to the acquisition profile reported for monolinguals with SLI and TD. Furthermore, L2-SLI children's accuracy with tense morphology was similar to that of their monolingual age peers with SLI at the end of the study, and exceeded that of younger monolingual peers with SLI whose age matched the L2 children's length of exposure to English. These findings are not consistent with the CEH, but instead show that morphological acquisition parallel to monolinguals with SLI is possible for L2 children with SLI.

Second language (L2) speakers often experience difficulty discriminating speech sounds of the nonnative language, which can result in phonolexical ambiguity. We report two experiments that examine how L2 Russian speakers may utilize contextual constraints for phonolexical ambiguity resolution during speech comprehension. L2 ambiguous words constitute minimal pairs with palatalized and unpalatalized consonants in the Russian language, where the phonological feature of palatalization marks semantic, morphological, or syntactic distinctions between words. L2 performance is compared to that of a control group of Russian native speakers. The results demonstrate that L2 listeners rely on contextual information for meaning disambiguation during sentence comprehension, but that the relative reliance on different types of context is task specific.

The present study tested the hypothesis (Byrne, 1996) that young children who do not yet understand that the elements of alphabetic writing represent phonemes link writing to language at the level of morphemes. We asked US preschoolers to write words that varied in the number of morphemes and the number of syllables that they contained. We identified a group of 50 children who used letters that represented phonemes in the intended words no more often than expected by chance (mean age = 4 years, 9 months). These prephonological spellers did not produce longer spellings for two-morpheme words such as teacup than for one-morpheme words such as napkin, although the length of their spellings was affected by the number of letters that they used to spell the previously presented word and by the order of the word in the experiment. The results suggest that the length of prephonological spellers’ productions is not influenced by the linguistic length of a message in phonemes, syllables, or morphemes, and they do not support the idea that these children show a special sensitivity to morphemes.

Psycholinguistic research has shown that sentence processing is incremental (e.g., Altmann & Kamide, 1999). In Japanese, a verb-final language, native speakers use case markers to incrementally assign thematic roles and predictively activate a structural representation of upcoming linguistic items. This study examined whether second-language learners of Japanese, guided by case markers, generate predictions as to whether the upcoming verb involves the active or passive voice. The results show that the native speakers made predictive eye movements before the verb, but the learners did not; the learners were less efficient in using case-marker cues than the native speakers and relied more on verb morphology information. These results suggest that case markers guide thematic role assignments, expediting the processing for Japanese native speakers. Learners may depend more on information from the verb to compensate for the inefficiency in case-marker-driven predictive processing.

Second language learners of English occasionally establish gender agreement between a possessive determiner and the local noun that follows it, rather than with its target antecedent (*“Maryi loves hisi brother”). The production and comprehension profiles of adult Mandarin second language learners of English and monolingual English-speaking children were examined to establish (a) if such errors result from an inherent tendency to establish agreement locally within the noun phrase or rather from transfer of first language agreement procedures, and (b) if these errors are production specific or rather reflect nontarget grammatical representations, thus also affecting comprehension. The results of the elicited production portion of the study support the hypothesis that gender agreement errors in learners’ production of possessives result from a generalized tendency to establish local agreement. The results of the comprehension portion of the study suggest that the observed tendency for local agreement within the noun phrase is production specific and does not characterize learners’ grammatical representations as a whole.
