Two separate studies examined older siblings’ influence on the language exposure and language development of US-born toddlers who were being raised in bilingual homes. The participants in Study 1 were 60 children between 16 and 30 months who had heard English and another language at home from birth; 26 had older siblings, and 34 did not. The participants in Study 2 were 27 children, assessed at 22 and 30 months, who had heard English and Spanish from birth; 14 had school-aged older siblings, and 13 did not. Both studies found that older siblings used English more in talking to the toddlers than did other household members and that toddlers with older siblings were more advanced in English language development. Study 2 also found that the presence of a school-aged older sibling increased mothers’ use of English with their toddlers and that toddlers without a school-aged older sibling were more advanced in Spanish than the toddlers with a school-aged older sibling. These findings contribute to a picture of the complex processes that shape language use in bilingual homes and cause variability in young children's bilingual development.

In spoken French, the phonological processes of liaison and resyllabification can render word and syllable boundaries ambiguous (e.g., un air “an air”/un nerf “a nerve,” both [.nɛʁ]). Production data have demonstrated that speakers of French vary the duration of consonants that surface in liaison environments relative to consonants produced word initially. Further research has suggested that listeners exploit these durational differences in the processing of running speech, although no study to date has directly tested this hypothesis. The current study examines the exploitation of duration in word recognition processes by manipulating this single acoustic factor while holding all other factors in the signal constant. The pivotal consonants in potentially ambiguous French sequences (e.g., /n/ in un nerf) were instrumentally shortened and lengthened and presented to listeners in two behavioral tasks. The results suggest that listeners are sensitive to segmental duration and use this information to modulate the lexical interpretation of spoken French.

Child English speakers use nonnominative pronouns in subject position but do not tend to use these types of pronouns with finite verbs. Recent findings demonstrate that knowledge of the pronoun paradigm is relevant to pronoun case errors below the 60% correct finiteness marking level but irrelevant above it. We use a receptive test with children who are above the 60% correct finiteness marking level and show that judgments of nominative case and verb finiteness correlate (r = .549, p < .001, n = 49), consistent with the predictions of case theory. Children at this level of finiteness marking show no asymmetry in feminine versus masculine nonnominative errors, but they do allow third singular –s with nonnominatives, which is problematic for both agreement tense omission model and constructivist priming accounts.

Emotional content of verbal material affects the speed of visual word recognition in various cognitive tasks, independently of lexicosemantic variables. However, little is known about how the dimensions of emotional arousal and valence interact with the lexicosemantic properties of words such as age of acquisition, familiarity, and imageability, that determine word recognition performance. This study aimed to examine these relationships using English ratings for affective and lexicosemantic features. Eighty-two native English speakers rated 300 words for emotional valence, arousal, familiarity, age of acquisition, and imageability. Although both dimensions of emotion were correlated with lexicosemantic variables, a unique emotion cluster produced the strongest quadratic relationship. This finding suggests that emotion should be included in models of word recognition as it is likely to make an independent contribution.

Cochlear implants allow many individuals with profound hearing loss to understand spoken language, even though the impoverished signals provided by these devices poorly preserve acoustic attributes long believed to support recovery of phonetic structure. Consequently, questions may be raised regarding whether traditional psycholinguistic theories rely too heavily on phonetic segments to explain linguistic processing while ignoring potential roles of other forms of acoustic structure. This study tested that possibility. Adults and children (8 years old) performed two tasks: one involving explicit segmentation, phonemic awareness, and one involving a linguistic task thought to operate more efficiently with well-defined phonetic segments, short-term memory. Stimuli were unprocessed (UP) signals, amplitude envelopes (AE) analogous to implant signals, and unprocessed signals in noise (NOI) that provided a degraded signal for comparison. Adults’ results for short-term recall were similar for UP and NOI, but worse for AE stimuli. The phonemic awareness task revealed the opposite pattern across AE and NOI. Children's results for short-term recall showed similar decrements in performance for AE and NOI compared to UP, even though only NOI stimuli showed diminished results for segmentation. Conclusions were that perhaps traditional accounts are too focused on phonetic segments, something implant designers and clinicians need to consider.

The extent to which risk for French as a second language (L2) reading and language learning impairment are distinct and can be predicted using first language (L1) predictors was examined in English-speaking students in total French immersion programs. A total of 86 children were tested in fall of kindergarten, spring kindergarten, and spring Grade 1 using an extensive battery of L1 predictor tests (in kindergarten) and L2 outcome tests (in Grade 1). Analyses of the kindergarten predictor scores revealed distinct underlying components, one related to reading and one to oral language. Further analyses revealed that phonological awareness, phonological access, and letter-sound knowledge in L1 were significant predictors of risk for reading difficulties in L2 while performance on L1 sentence repetition, phonological awareness, and tense marking tests in kindergarten were the best predictors of risk for L1 and L2 oral language difficulties. Both fall- and spring-kindergarten predictors predicted Grade 1 outcomes to a significant extent, with the spring-kindergarten predictors being more accurate. These results provide support for distinctive risk profiles for L2 oral language and reading difficulty and, furthermore, argue that assessment of L1 abilities can be used to make reasonably accurate predictions of later reading and/or oral language learning difficulties in L2 students.

Foreign language (FL) films with subtitles are becoming increasingly popular, and many European countries use subtitling as a cheaper alternative to dubbing. However, the extent to which people process subtitles under different subtitling conditions remains unclear. In this study, participants watched part of a film under standard (FL soundtrack and native language subtitles), reversed (native language soundtrack and FL subtitles), or intralingual (FL soundtrack and FL subtitles) subtitling conditions while their eye movements were recorded. The results revealed that participants read the subtitles irrespective of the subtitling condition. However, participants exhibited more regular reading of the subtitles when the film soundtrack was in an unknown FL. To investigate the incidental acquisition of FL vocabulary, participants also completed an unexpected auditory vocabulary test. Because the results showed no vocabulary acquisition, the need for more sensitive measures of vocabulary acquisition are discussed. Finally, the reading of the subtitles is discussed in relation to the saliency of subtitles and automatic reading behavior.

According to usage-based approaches to acquisition, the detection of a construction may be facilitated when input contains numerous exemplars with a shared lexical item, which is referred to as skewed input. First language studies have shown that skewed input is more beneficial for the acquisition of novel constructions than balanced input, in which a small set of lexical verbs occurs an equal number of times. However, a second language (L2) study of datives found no advantage for skewed input compared to balanced input. The present study compared the effectiveness of skewed and balanced input at facilitating the comprehension of the double-object dative construction in L2 English. Over a 2-week period, Thai English as foreign language learners (N = 78) completed comprehension tests and a treatment activity that provided either skewed first, skewed random, or balanced input. The results indicated that balanced input was most effective at promoting comprehension of double-object datives. The implications are discussed in terms of the benefits of different types of input for L2 learners.
