This study investigated whether third person singular –s and past tense accuracy and error types can reveal distinct developmental patterns of agreement and tense acquisition in younger and older Welsh (L1) sequential bilingual (L2) English children with typical development (L2-TLD) and in younger children with language impairment (L2-SLI_Y). A group of older (L2-TLD_O; mean age = 93.72 months) and younger (L2-TLD_Y; mean age = 67 months) Welsh–English (TLD) bilingual children and a group of young (mean age = 63 months) children with SLI (L2-SLI_Y) age matched to the L2-TLD_Y group were administered the screening component of the Test of Early Grammatical Impairment. Results indicated that the three groups differed in their production of third person singular –s and regular past tense but not in accuracy on irregular past tense verbs, when vocabulary skills were considered. The L2-SLI_Y children produced similar error types to the L2-TLD_Y children, who differed from their L2-TLD_O peers in this respect. L2 children’s vocabulary size, nonverbal intelligence, and item-level factors, such as frequency and morphophonology, differentially contributed to their performance across the various morphemes. We discuss these results within current accounts of language development and impairment.

Immigrant children in Denmark differ greatly in educational outcomes. This study examined whether systematic differences in majority language (L2) and preliteracy skills are apparent already at ages 2–6 in immigrant children in Denmark across regional immigration background. Danish language and preliteracy skills in 1,211 immigrant children in four regional groups (based on maternal origin) and 11,259 native Danish nonimmigrant children, all enrolled in Danish childcare centers, were assessed using an age- and gender-normed language assessment instrument. Hierarchical linear models showed that all four immigrant groups scored significantly lower than the native Danish group; the negative coefficients diminished but remained significant when socioeconomic background and having a native Danish father were controlled for. In addition, even with these controls, significant differences existed between some of the immigrant groups, suggesting that factors relating to regional immigrant background were important sources of differences in L2 development. A greater immigrant disadvantage for language than preliteracy skills was found; two immigrant groups did not differ significantly from the nonimmigrant Danish group for preliteracy skills. The results suggest that measures to reduce inequalities in long-term educational achievement between immigrant groups should be taken already before school with a particular focus on L2 language skills.

While the relationship between vocabulary, morphological awareness, and reading comprehension has been examined extensively, research on this relationship among adult second language learners has only been explored recently. The present study addresses this gap by examining how adult English as a foreign language learners developed different types of English vocabulary and morphological awareness over the course of one academic year. Participants included 523 college freshmen in Taiwan with varying reading proficiency levels. Results from a series of mixed-measure analyses of variance revealed that (a) even the more proficient college English as a foreign language learners failed to fully grasp morphological principles; (b) the gap in vocabulary between the less skilled readers, the average, and the skilled readers widened significantly over the course of one academic year; (c) the effect of phonological and orthographic changes involved in morphologically complex words differed for the assessment of base meaning, but did not vary across proficiency levels; (d) progress in different aspects of morphological awareness, such as interpreting the meaning of the suffix or identifying the base of a morphologically complex word, varied significantly among readers of different proficiency levels; and (e) suffixes of different parts of speech posed different challenges to learners. Theoretical and pedagogical implications of the findings are discussed.

Speech production is influenced by the orthographic representation of the spoken word. Although previous work has shown that inconsistencies between the word’s sound and spelling may facilitate or disrupt processing (e.g., Alario, Perre, Castel, & Ziegler, 2007; Saletta, Goffman, & Brentari, 2015; Saletta, Goffman, & Hogan, 2016; Ventura, Morais, Pattamadilok, & Kolinsky, 2004), the developmental course of this effect on new readers remains unclear. The current study examines how children’s production of nonwords changes as a function of exposure to the nonwords’ orthography. We tested nonword repetition in 17 children with typical reading skills and 17 children with poor reading skills. Participants heard and repeated nonword stimuli, or read them aloud when the stimuli were written in either a relatively transparent or an opaque spelling. We quantified participants’ segmental accuracy and speech movement stability both before and after their exposure to the nonwords’ orthography. The children improved only in segmental accuracy (and not speech movement stability) and only as a consequence of practice (and not because of exposure to the nonwords’ spellings). Children with poorer reading skills demonstrated a greater change in accuracy from pretest to posttest than children with stronger reading skills. Thus, one’s automaticity in reading and the reorganization of his/her literacy skills throughout development influence speech production.

The current study investigated the comprehension of subject and object relative clauses (RCs) in bilingual Mandarin–English children (N = 55, Mage = 7 years, 5 months [7;5], SD = 1;8) and language-matched monolingual Mandarin-speaking children (N = 59, Mage = 5;4, SD = 0;7). The children completed a picture-referent selection task that tested their comprehension of subject and object RCs, and standardized assessments of vocabulary knowledge. Results showed a very similar pattern of responding in both groups. In comparison to past studies of Cantonese, the bilingual and monolingual children both showed a significant subject-over-object RC advantage. An error analysis suggested that the children’s difficulty with object RCs reflected the tendency to interpret the sentential subject as the head noun. A subsequent corpus analysis suggested that children’s difficulty with object RCs may be in part due to distributional information favoring subject RC analyses. Individual differences analyses suggested crosslinguistic transfer from English to Mandarin in the bilingual children at the individual but not the group level, with the results indicating that comparative English dominance makes children vulnerable to error.

Animacy is one of the basic semantic features of word meaning and influences perceptual and episodic memory processes. However, evidence that this variable also influences lexicosemantic processing is mixed. As animacy is a semantic variable thought to have evolutionary roots, we first examined its influence in a semantic categorization task that did not make the animacy dimension salient, namely, concrete-abstract categorization. Animates were categorized faster (and more accurately) than inanimates. We then assessed the influence of animacy in two lexical decision experiments. In Experiment 2, we mostly used legal nonwords, whereas in Experiment 3, we varied the context of the nonwords across participants in such a way that the discriminability between words and nonwords was either high or low. Animates yielded faster decision times than inanimates when legal nonwords were used (Experiment 2) and when the discriminability between words and nonwords was low (i.e., “difficult nonwords” in Experiment 3), but the difference between the two types of words was not reliable when discriminability was high (e.g., illegal strings of letters, i.e., “easy nonwords” in Experiment 3). The findings suggest that animacy is a core meaning-related dimension that influences a large number of processes involved in perception, episodic memory, and semantic memory.

Usage-based approaches to language acquisition posit that first (L1) and second language (L2) speakers should process more frequent compositional phrases, which have a meaning derivable from word parts, faster than less frequent ones (e.g., Bybee, 2010; Ellis, 2011). Although this prediction has received increasing empirical support, methodological limitations in previous relevant studies include a lack of control of frequencies of subparts of target phrases and scant attention to L2 production. Addressing these limitations, the current study tested phrase frequency effects in both language comprehension and production in two respective experiments, in which adult native English speakers (N = 51) and English L2 learners (N = 52) completed a timed phrasal decision task and an elicited oral production task. Experiment 1 revealed phrase frequency effects in both groups, lending support to usage-based researchers’ proposal that L1 and L2 speakers retain memory of word co-occurrences and that compositional phrase processing reflects an accumulation of statistics in previously encountered input. Experiment 2, however, provided weaker evidence for phrase frequency effects in these participant groups. Based on the results and previous empirical studies, methodological issues that may have impacted frequency effects and implications for future work in this area are discussed.

This study explored the long-term effects of limited input on bilingual teenagers’ acquisition of complex morphology in Welsh. Study 1 assessed 168 12–13 and 16–17-year-old teenagers, across three bilingual groups: those whose first language was Welsh (L1 Welsh), those who learned Welsh and English simultaneously (L1 Welsh–English), and those who learned Welsh as a second language (L2 Welsh), on their receptive knowledge of grammatical gender. Study 2 assessed the same participants on their production of plural morphology. While the results of Study 1 revealed continuous progression toward adult norms among L1 Welsh-speaking bilinguals, with the simultaneous bilinguals progressing at a slower rate, the results of Study 2 revealed performances on plural morphology that were comparable to adult norms among the 16–17-year-old L1 Welsh-speaking bilinguals, and some progression among the simultaneous bilinguals. In contrast, delayed progression was seen among the L2 Welsh-speaking bilinguals across the board, with 16–17-year-old L2 participants lagging behind their L1 peers on both grammatical gender and plural morphology. The implications of these findings for our understanding of the long-term outcomes for bilinguals learning complex structures under minority language conditions are discussed.

We examined whether morphological awareness made a significant contribution to word-level reading across Grades 1 to 4. We test these relations specifically in a task measuring awareness of past-tense forms. A total of 375 children from Grades 1 to 4 completed tasks assessing past-tense morphological awareness along with real word and pseudoword reading. Children also completed control measures assessing phonological awareness, phonological short-term memory, sentence-level language skills, and nonverbal cognitive ability. After these controls, past-tense morphological awareness was a significant predictor of real word reading in Grades 1 and 2, but not in Grades 3 and 4. Further, following on all controls, past-tense morphological awareness was a consistent predictor of pseudoword reading across Grades 1 to 4. Morphological awareness, at least as measured with past-tense verbs, appears to have a role in word reading across the early to middle elementary school grades; for young readers, there are relations to reading of both known and novel words, and for older readers, relations are significant specifically in reading novel words. These findings are discussed within the context of theories of word reading development.
