The foreign language vocabulary learning research literature often attributes strong mnemonic potency to the cognitive processing of meaning when learning words. Routinely cited as support for this idea are experiments by Craik and Tulving (C&T) demonstrating superior recognition and recall of studied words following semantic tasks (“deep” encoding) compared to structure-related tasks (“shallow” encoding). However, participants in C&T were not language learners but native speakers of English studying known English nouns. These experiments have never been directly replicated using nonnatives to establish the relevance of the findings to nonnatives and learners. The present study replicated C&T Experiment 5, comparing effects of shallow and deep encoding tasks on subsequent recognition of target words by native and nonnative speakers of English with equivalent short-term memory function. The results showed depth effects similar to C&T for all participants, indicating that C&T's results do generalize to less proficient speakers of the target language. It is crucial, however, that nonnative speakers of English benefited less from semantic encoding than native speakers, suggesting an effect of preexisting knowledge representations on mnemonic effects derived from semantic processing, and hence, a limit to the relevance of C&T for learners. Results are discussed in terms of the constructs of the mental lexicon, expert knowledge, distinctiveness and levels of processing in memory research and language learning.

In this study, 5-year-olds and adults described scenes that differed according to whether (a) the subject or object of a transitive verb represented an accessible or inaccessible referent, consistent or inconsistent with patterns of preferred argument structure, and (b) a simple noun was sufficient to uniquely identify an inaccessible referent. Results showed that although adults did not differ in their choice of referring expression based on sentence position, 5-year-olds were less likely to provide informative referring expressions for subjects than for objects when the referent was inaccessible. In addition, under complex discourse conditions, although adults used complex noun phrases to identify inaccessible referents, 5-year-olds increased their use of pronominal/null reference for both accessible and inaccessible referents, thus reducing their levels of informativeness. The data suggest that 5-year-olds are still learning to integrate their knowledge of discourse features with preferred argument structure patterns, that this is particularly difficult in complex discourse contexts, and that in these contexts children rely on well-rehearsed patterns of argument realization.

This study investigated the role of typological relatedness, language of the community, and age, in predicting similarities and differences between English–Italian, Spanish–Italian bilingual children and their monolingual child and adult counterparts in the acceptability of pre- and postverbal object pronouns in [±focus] contexts in Italian and in English. Cross-linguistic influence occurred in [−focus] contexts as a function of typological relatedness and language of the community. English–Italian bilinguals in the UK accepted pragmatically inappropriate postverbal pronouns in [−focus] contexts in Italian twice as often as all the other groups. Cross-linguistic influence was unidirectional from English to Italian as shown by the categorical rejection of preverbal pronouns in [−focus] contexts in English. In [+focus] contexts, in English no significant differences existed between the monolinguals and the bilinguals in the low accuracy with which they chose pragmatically appropriate stressed pronouns. Similarly, the choice of appropriate pronouns in [+focus] contexts in Italian was problematic for monolingual and bilingual children irrespective of the language of the community and of the bilinguals’ other language. Age was a factor only for the Italian children who approached adultlike performance in [+focus] contexts only by the age of 10. These findings point to the need for a multifaceted approach to account for similarities and differences between the linguistic behavior of bilingual and monolingual children.

Knowledge of compound word structures in Chinese and English was investigated, comparing 435 Chinese and 258 Americans, including second, fourth, and sixth graders, and college undergraduates. As anticipated, the results revealed that Chinese speakers performed better on a word structure analogy task than their English-speaking counterparts. Also, as anticipated, speakers of both languages performed better on noun + noun and verb + particle compounds, which are more productive in their respective languages than noun + verb and verb + noun compounds, which are less productive. Both Chinese and English speakers performed significantly better on novel compounds than on familiar compounds, most likely because familiar compounds are lexicalized and do not invite decomposition into constituents.

The relation of social and linguistic input measures to early vocabulary development was examined in 30 low-income African American mother–infant pairs. Observations were conducted when the child was 0 years, 1 month (0;1), 0;4, 0;8, 1;0, 1;6, and 2;0. Maternal input was coded for word types and tokens, contingent responsiveness, and directiveness. Children's outcome measures included productive vocabulary at 1;6 and 2;0. Patterns of social and linguistic input were highly consistent over time. Significant positive relations were found between linguistic input measures and child vocabulary development. Findings for social input measures included positive relations between directive input and child word types, which differs from previous research with European American middle-class samples.

This study aims to explain how the practice of two languages (French and Creole) in French overseas departments affects the first educational competencies acquired by children. The students’ performance in both languages was investigated at the beginning of kindergarten, and their reading capacities were measured at the end of Grade 1. The data analysis shows that the practice of Creole has no negative impact on success at reading in French. Furthermore, it appears that the students who performed the best in reading were those who were either more competent in French than in Creole, or those who were equally competent in both languages, according to their assessed reading competence. Thus, also discussed is the necessity of early exposure to a language's written code and the contribution that bilingualism makes to learning processes of reading.

Language development is frequently characterized as a process where learning proceeds implicitly, that is, incidentally and in absence of awareness of what was learned. This article reports the results of two experiments that investigated whether second language acquisition can also result in implicit knowledge. Adult learners were trained on an artificial language under incidental learning conditions and then tested by means of grammaticality judgments and subjective measures of awareness. The results indicate that incidental exposure to second language syntax can result in unconscious knowledge, which suggests that at least some of the learning in this experiment was implicit. At the same time, however, it was also found that conscious (but unverbalizable) knowledge was clearly linked to improved performance in the grammaticality judgment task.
