The present study investigated whether German speakers compute grammatical gender on the basis of gender-marking regularities. To this purpose two experiments were run. In Experiment 1, participants had to assign the definite article to German nouns in an online task; in the second experiment, participants were confronted with German nouns as well as nonwords in an untimed gender assignment task. In the online experiment, which required the repetition of a visually presented noun with its corresponding definite article as fast as possible, reaction times show that the assignment of the definite determiner to a noun is not facilitated by gender-marking regularities. In an offline gender assignment task, however, participants profited from gender cues during gender assignment to nonwords.

A semantic priming, lexical-decision study was conducted to examine the ability of left- and right-brain damaged individuals to perceive lexical-stress cues and map them onto lexical–semantic representations. Correctly and incorrectly stressed primes were paired with related and unrelated target words to tap implicit processing of lexical prosody. Results conformed with previous studies involving implicit perception of lexical stress, in that the left-hemisphere damaged individuals showed preserved sensitivity to lexical stress patterns as indicated by priming patterns mirroring those of the normal controls. An increased sensitivity to the varying stress patterns of the primes was demonstrated by the right-hemisphere damaged patient group, however. Results are discussed in relation to current theories of prosodic lateralization, with a particular focus on the nature of task demands in lexical stress perception studies.

Immigrants' age of arrival (AOA) in a country where a second language (L2) must be learned has consistently been shown to affect the degree of perceived L2 foreign accent. Although the effect of AOA appears strong, AOA is typically correlated with other variables that might influence degree of foreign accent. This study examined the pronunciation of English by native Italian immigrants to Canada who differed in AOA. As in previous research, those who arrived as young adults (late learners) were somewhat older at the time of testing, and produced somewhat longer English sentences, than those who arrived in Canada when they were children (early learners). The results of Experiment 1 showed that the greater chronological age of early than late learners was not responsible for the late learners' stronger foreign accents. Experiment 2 suggested that the late learners' longer L2 sentences were not responsible for observed early–late foreign accent differences. A principle components analysis revealed that variation in AOA and language use, but not chronological age or sentence duration, accounted for a significant amount of variance in the foreign accent ratings. The findings of the study were interpreted to mean that AOA effects on foreign accent are due to the development of the native language phonetic system rather than to maturational constraints on L2 speech learning.

To examine effects of input and learner characteristics on morphology acquisition, 60 adult English speakers learned to inflect masculine and feminine Russian nouns in nominative, dative, and genitive cases. By varying training vocabulary size (i.e., type variability), holding constant the number of learning trials, we tested whether learners required a “critical mass” of vocabulary to generalize case marking patterns to new nouns. Cattell's Culture-Fair IQ Test mediated the effect of type variability on success in generalizing case marking to new vocabulary: only participants with above-median Culture-Fair Test scores showed the predicted critical mass effect of better generalization with larger training vocabulary. These results demonstrate how individual differences in central executive functioning and attention allocation capacity can affect adult second language learning.

To examine the factors that affect the learning of letter names, an important foundation for literacy, we asked 318 US and 369 Brazilian preschoolers to identify each uppercase letter. Similarity of letter shape was the major determinant of confusion errors in both countries, and children were especially likely to interchange letters that were similar in shape as well as name. Errors were also affected by letter frequency, both general frequency and occurrence of letters in children's own names. Differences in letter names and letter frequencies between English and Portuguese led to certain differences in the patterns of performance for children in the two countries. Other differences appeared to reflect US children's greater familiarity with the conventional order of the alphabet. Boys were overrepresented at the low end of the continuum of letter name knowledge, suggesting that some boys begin formal reading instruction lacking important foundational skills.

This study explores influences on bilingual children's phonological awareness (PA) performance in English, examining the role of language of instruction and vocabulary. English monolingual and Spanish–English bilingual kindergartners and first graders receiving either English or Spanish literacy instruction were assessed in English PA and in English and Spanish vocabulary, as appropriate. Spanish-instructed bilinguals were more likely than English-instructed bilinguals or English monolinguals to treat diphthongs as two units, reflecting their analysis in Spanish phonology and orthography. Surprisingly, unbalanced bilinguals dominant in either English or Spanish scored better on English PA than children with approximately equal scores on the English and the Spanish vocabulary test. This finding suggests that familiarity with many lexical items within a language constitutes a source of analyzable phonological knowledge.

In two experimental training studies we examined the hypothesis that an emphasis on the meaning of a word is more effective than merely focusing on the orthography to increase reading fluency. Reading delayed children from Grade 1 (mean age = 7.3 years) and two groups from Grade 2 (mean age = 8.3 and 7.8 years) repeatedly read words while focusing either on the orthography or on the semantics of the word. Furthermore, the claim that limited exposure duration during training further promotes fluency was examined. The results show that the semantic based exercises yield more effect than orthographic training, especially for Grade 2 students. No beneficial effect is found for limited presentation duration. The results strongly suggest that practice with printed words with a specific focus on the semantic characteristics effectively promotes the attainment of reading fluency.

The production of passive sentences by children with specific language impairment (SLI) was studied in two languages, English and Cantonese. In both languages, the word order required for passive sentences differs from the word order used for active sentences. However, English and Cantonese passive sentences are quite different in other respects. We found that English-speaking children with SLI were less proficient than both same-age and younger typically developing peers in the use of passives, although difficulty could not be attributed to word order or a reliance on active sentences. Cantonese-speaking children with SLI proved less capable than same-age peers in their use of passive sentences but at least as proficient as younger peers. The implications of these cross-linguistic differences are discussed.
