Many studies show that poor readers make more errors in nonword repetition than better readers. Although this finding is generally linked to the lower quality of poor readers’ phonological representations in verbal short-term memory, the nature of this poor performance remains unclear. We addressed this issue by focusing on two types of phoneme-related performance in a nonword repetition task: (a) recall of phonemes irrespective of their serial order (phoneme identity) and (b) recall of correctly reproduced phonemes’ serial order (serial order). We tested 91 young adults with and without dyslexia. Generalized linear mixed-effects models demonstrated that controls outperformed individuals with dyslexia in the recall of phonemes’ serial order but failed to detect a difference in the recall of phonemes’ identity. These findings are discussed not only in terms of the nature of or access to phonological representations but also in terms of another concept that has recently been advanced in the literature: a specialized serial order mechanism in verbal short-term memory. We also consider the possibility that individuals with dyslexia may be less sensitive to phonotactic constraints.

This article examines the performance of heritage speakers (HSs) on two types of acceptability judgment tasks (AJTs) as well as their corresponding confidence ratings. Data were collected from 75 native speakers of Spanish who were subsequently divided into three groups: Spanish monolinguals, Spanish-dominant HSs, and English-dominant HSs. An AJT targeting morphosyntax (Task 1) showed that all groups were affected by task stimulus, that is, they were significantly less accurate on the ungrammatical items. A lexically focused AJT (Task 2) revealed the tendency of HSs to accept complex words that are possible yet not attested. Confidence ratings on both tasks were very high overall, and there was a significant relationship between accuracy and confidence. Thus, the data question the assumption made in a number of previous studies that HSs suffer from a lack of certainty in their linguistic intuitions. Finally, between-group effects show that the Spanish-dominant HS group was not different from the monolingual group on Task 1, yet there were significant differences between all three groups on Task 2. By comparing morphosyntactic and lexical phenomena on two tasks administered in the same modality, this research contributes to the discussion of vulnerable domains in heritage language bilingualism.

This study examines the effects of two cognitive abilities—language analytic ability (LAA) and working memory (WM)—on language learning under five different instructional conditions. One hundred fifty eighth-grade English as a foreign language learners underwent a 2-hr treatment session. They were divided into five groups based on whether and when they received form-focused instruction. One group received pretask instruction on the linguistic target (English passive voice) before performing two narrative tasks; a second group received within-task feedback but no pretask instruction; a third group received both pretask instruction and within-task feedback; a fourth group received feedback after completing the tasks; and the fifth group only performed the tasks. The results showed that (a) LAA was predictive of the posttest scores of the group that only performed the communicative tasks and the group who received posttask feedback, (b) WM was associated with the learning outcomes of the two groups receiving within-task feedback, and (c) neither cognitive variable was implicated in the group that received pretask instruction before performing the tasks. The results suggest that the impact of LAA is evident when there is less external assistance and that WM is involved when learners face the heavy processing burden imposed by within-task feedback.

Phonological similarity effects are biases to judge words as phonologically similar (i.e., rhyming), even if they are not. First found in rime awareness tasks in preliterates, these biases have recently also been found in proficient adult readers. In this study, we evaluated underlying phonological processing in rime judgment longitudinally, across literacy development. To this end, we created a new rime judgment task (rime; i.e., /t∙aɪ̯∙l/ - /z∙aɪ̯∙l/) with two distractor conditions that varied in size of phonological overlap (body; i.e., /t∙aɪ̯∙l/ - /t∙aɪ̯ ç/; nucleus; i.e., /t∙aɪ̯∙l/ - /r∙aɪ̯∙s/). The task was administered to a group of 61 German-speaking children at four time points across school entry and to 21 adults. Accuracy and latency responses were recorded. Results indicated that children and adults showed phonological similarity effects but the effect decreased gradually over time. However, preliterate children were more sensitive to large compared to small phonological overlap, while the same effect was significantly smaller in literate children and adults. Results suggest that preliterate children are more sensitive to larger grain sizes and become more sensitive to fine-grained units across literacy development. The findings are in line with the assumptions of the psycholinguistic grain size theory.

This research reports on a quantitative analysis of the combination of two types of disfluency, reformulations and pauses, in the speech of lower intermediate and advanced speakers of English as a second language (L2). The present study distinguishes between corrections and false starts within the category of reformulations as well as between silent and filled pauses. It focuses on the extent to which pause behavior within reformulations varies according to the stage of L2 development and the type of reformulation used. An analysis was made of 56 L2 speakers’ 2-min monologues. The results showed that lower intermediate and advanced speakers differed on the frequency of silent pauses inserted in corrections but not on their frequency in false starts. This suggests that false starts depend less on proficiency level, and may reflect temporary problems with conceptual encoding or extralinguistic factors that contribute to the efficacy of L2 production rather than difficulties with linguistic processing per se. The frequency of silent pauses rather than silent pause duration or the frequency and duration of filled pauses appeared to be the only marker to differentiate between false starts and corrections across the two proficiency groups.

We examined morphological awareness and reading achievement in university students in two ways. First, students with and without a self-reported history of reading difficulties were compared on word reading and text reading achievement, and on the reading-related skills of morphological awareness, orthographic processing, and phonological processing. Second, the unique contribution of morphological awareness to reading achievement was examined for a larger sample of first-year university students. Students with a self-reported history of reading difficulties (n = 54) showed moderate to large gaps in each area of reading achievement, and timed reading comprehension appeared more severely impaired than word-reading efficiency. These students had a deficit in morphological awareness that persisted even when (a) phonological awareness and orthographic processing skills, or (b) word-reading accuracy were statistically controlled. In the larger first-year sample (N = 211), morphological awareness contributed to variance in word reading beyond that accounted for by phonological awareness and orthographic processing. Furthermore, of the reading-related skills, only morphological awareness made a unique contribution to reading comprehension beyond variance accounted for by word reading. Taken together, these results demonstrate that morphological awareness makes unique contributions to university students’ reading achievement and is an additional difficulty for students with a self-reported history of reading difficulties.

This study investigates the shared, independent, and interactive effects of metalinguistic skills (phonological awareness, morphological awareness, and orthographic knowledge) to word reading with a sample of struggling adult readers. Controlling for vocabulary knowledge, a second-order latent factor of metalinguistic awareness accounted for unique variance (62.5%) in adults’ word reading skills. Two-way latent interactions between the metalinguistic skills (phonological awareness × morphological awareness, morphological awareness × orthographic knowledge, and phonological awareness × orthographic knowledge) revealed unique interactive contributions (1%–5.2%) of these skills to word reading controlling for the metalinguistic skill main effects and vocabulary knowledge. In particular, high levels of morphological awareness are critical to word reading irrespective of high or low phonological awareness and orthographic knowledge. In addition, higher phonological awareness skills are critical to word reading irrespective of high or low orthographic knowledge. These results indicate the importance as well as the complexity of the nature of metalinguistic skills underlying word reading for struggling adult readers. The theoretical, empirical, and applied implications of these findings are discussed in the context of researchers and practitioners invested in improving outcomes in adult literacy programs.

The study explores the effect of deviations from native speech rhythm and rate norms on the assessement of pronunciation mastery of a second language (L2) when the native language of the learner is either rhythmically similar to or different from the target language. Using the concatenative speech synthesis technique, different versions of the same sentence were created in order to produce segmentally and intonationally identical utterances that differed only in rhythmic patterns and/or speaking rate. Speech rhythm and tempo patterns modeled those from the speech of French or German native learners of English at different proficiency levels. Native British English speakers rated the original sentences and the synthesized utterances for accentedness. The analysis shows that (a) differences in speech rhythm and speaking tempo influence the perception of accentedness; (b) idiosyncratic differences in speech rhythm and speech rate are sufficient to differentiate between the proficiency levels of L2 learners; (c) the relative salience of rhythm and rate on perceived accentedness in L2 speech is modulated by the native language of the learners; and (d) intonation facilitates the perception of finer differences in speech rhythm between otherwise identical utterances. These results emphasize the importance of prosodic timing patterns for the perception of speech delivered by L2 learners.
