  While a number of studies have found that an improvement in object shape recognition is associated with language growth in infants and toddlers, no published studies have investigated the longitudinal relation between early shape recognition, and language abilities in later childhood. An electrophysiological measure of semantic processing (the N400) was used to assess shape recognition and general object recognition in a naming context in 20-month-olds. The measures of shape recognition strongly predicted language and cognitive abilities at 6–7 years even after controlling for toddler vocabulary size. The electrophysiological measures of general object recognition were not related to future language or cognitive abilities. These results suggest that early shape recognition abilities may play a role in language acquisition and influence even long-term language outcomes.

  According to the Norwegian Framework Plan for Kindergartens (Ministry of Education 2017: 24), the staff shall ‘monitor the children’s communication and language and identify and support children who demonstrate various types of communication problems, who are not linguistically active, or who show signs of delayed language development’. As a first step in the development of an assessment tool that may meet this requirement from the framework plan, we have piloted the Norwegian parental report MacArthur-Bates CDI III (Communicative Development Inventories (Fenson et al. 2007)) with monolingual three-year-olds. The results suggest that CDI III is a reliable and valid tool for the assessment of these children’s language skills. We have also compared CDI III reports from parents and Early Childhood Education and Care (ECEC) staff and found acceptable correlations between the reported scores.

  Although the majority of early implanted, profoundly deaf children with cochlear implants (CIs), will develop correct pronunciation if they receive adequate oral language stimulation, many of them have difficulties with perceiving minute details of speech. The main aim of this study is to measure the confusion of consonants and vowels in well-performing children and adolescents with CIs. The study also aims to investigate how age at onset of severe to profound deafness influences perception. The participants are 36 children and adolescents with CIs (18 girls), with a mean (SD) age of 11.6 (3.0) years (range: 5.9–16.0 years). Twenty-nine of them are prelingually deaf and seven are postlingually deaf. Two reference groups of normal-hearing (NH) 6- and 13-year-olds are included. Consonant and vowel perception is measured by repetition of 16 bisyllabic vowel-consonant-vowel nonsense words and nine monosyllabic consonant-vowel-consonant nonsense words in an open-set design. For the participants with CIs, consonants were mostly confused with consonants with the same voicing and manner, and the mean (SD) voiced consonant repetition score, 63.9 (10.6)%, was considerably lower than the mean (SD) unvoiced consonant score, 76.9 (9.3)%. There was a devoicing bias for the stops; unvoiced stops were confused with other unvoiced stops and not with voiced stops, and voiced stops were confused with both unvoiced stops and other voiced stops. The mean (SD) vowel repetition score was 85.2 (10.6)% and there was a bias in the confusions of [i:] and [y:]; [y:] was perceived as [i:] twice as often as [y:] was repeated correctly. Subgroup analyses showed no statistically significant differences between the consonant scores for pre- and postlingually deaf participants. For the NH participants, the consonant repetition scores were substantially higher and the difference between voiced and unvoiced consonant repetition scores considerably lower than for the participants with CIs. The participants with CIs obtained scores close to ceiling on vowels and real-word monosyllables, but their perception was substantially lower for voiced consonants. This may partly be related to limitations in the CI technology for the transmission of low-frequency sounds, such as insertion depth of the electrode and ability to convey temporal information.

  Learning to read is a milestone in a child's life, and reading ability is a strong predictor of academic outcomes. Some studies have revealed that individual differences in the capacity for implicit statistical learning are linked with children's reading skills in English, which has a deep orthography, but we do not know whether the same relation is found in semi-transparent orthographies such as Norwegian. Additionally, the relative contribution of statistical learning alongside other cognitive measures known to be related to reading has not been examined. This study of sixty-five Norwegian school children (M=10.3 years) found that performance on an independent statistical learning task predicted a small, but unique amount of variance in reading ability in Norwegian, even when a number of other reading-related cognitive skills were taken into account. This suggests that children's implicit learning of statistical regularities is associated with proficiency with written language in a semitransparent orthography such as Norwegian.

  Children with hearing loss, and those with language disorders, can have excellent speech recognition in quiet, but still experience unique challenges when listening to speech in noisy environments. However, little is known about how speech-in-noise perception relates to individual differences in cognitive and linguistic abilities in these children. The present study used the Norwegian version of the Hearing in Noise Test (HINT) to investigate speech-in-noise perception in 175 children aged 5.5-12.9 years, including children with cochlear implants (CI, n = 64), hearing aids (HA, n= 37), developmental language disorder (DLD, n = 16) and typical development (TD, n= 58). Further, the study examined whether general language ability, verbal memory span, nonverbal IQ and speech perception of monosyllables and sentences in quiet were predictors of performance on the HINT. To allow comparisons across ages, scores derived from age-based norms were used for the HINT and the tests of language and cognition. There were significant differences in speech-in-noise perception between all the groups except between the HA and DLD groups, with the CI group requiring the highest signal-to-noise ratios (i.e. poorest performance) and the TD group requiring the lowest signal-to-noise ratios. For the full sample, language ability explained significant variance in HINT performance beyond speech perception in quiet. Follow-up analyses for the separate groups revealed that language ability was a significant predictor of HINT performance for children with CI, HA and DLD, but not for children with TD. Memory span and IQ did not predict variance in speech-in-noise perception when language ability and speech perception in quiet were taken into account. The finding of a robust relation between speech-in-noise perception and general language skills in all three clinical groups call for further investigation into the mechanisms that underlie this association.

  Dichotic listening (DL) taps information on the brain's lan-guage laterality, processing, and attention. Research hasshown that DL responses in dyslexia deviate from the typi-cal pattern. Here, effects of DL training and its correspon-dence to rapid naming (RAN) and digit span (DS) in typicalchildren and children with dyslexia were assessed. Threegroups of third graders participated: two training groups,control training (CT) and dyslexia training (DT), and a controlgroup that received no training (control no training, CnT). Alltook part in testing pretraining and posttraining. DL mea-sures were on laterality, response scores, and attention.The three groups showed different response patterns:minor changes in CnT, change in all measures in CT, andsome changes in DT. RAN and DS scores correlated signifi-cantly with some of the DL measures, especially with theattention scores. Our findings support arguments that brainarchitecture for language in dyslexia is lateralised in thesame way as in children without dyslexia. However, theability to modulate attention during DL is weaker in dyslexiathan in typically developing children. A training‐inducednormalisation of lateralisation was observed in free recallin the dyslexia group, which suggests that DL training maybe a promising intervention approach.

  This longitudinal ERP study investigated changes in children’s ability to map novel words to novel objects during the dynamic period of vocabulary growth between 20 and 24 months. During this four-month period the children on average tripled their productive vocabulary, an increase which was coupled with changes in the N400 effect to pseudoword-referent associations. Moreover, productive vocabulary size was related to the dynamics of semantic processing during novel word learning. In children with large productive vocabularies, the N400 amplitude was linearly reduced during the five experimental learning trials, consistent with the repetition effect typically seen in adults, while in children with smaller vocabularies the N400 attenuation did not appear until the end of the learning phase. Vocabulary size was related only to modulation of the N400 to pseudowords, not to real words. These findings demonstrate a remarkable development of fast mapping ability between 20 and 24 months.

  In this study of third grade school children, we investigated the association between writing process measures recorded with key stroke logging and the final written product. Moreover, we examined the cognitive predictors of writing process and product measures. Analyses of key strokes showed that while most children spontaneously made local online revisions while writing, few revised previously written text. Children with good reading and spelling abilities made more online revisions than their peers. Two process factors, transcription fluency and online revision activity, contributed to explaining variance in narrative macrostructural quality and story length. As for cognitive predictors, spelling was the only factor that gave a unique contribution to explaining variance in writing process factors. Better spelling was associated with more revisions and faster transcription. The results show that developing writers’ ability to make online revisions in creative writing tasks is related to both the quality of the final written product and to individual literacy skills. More generally, the findings indicate that investigations of the dynamics of the writing process may provide insights into the factors that contribute to creative writing during early stages of literacy.

  Statistical learning (SL) studies have shown that participants are able to extract regularities in input they are exposed to without any instruction to do so. This and other findings, such as the fact that participants are often unable to verbalize their acquired knowledge, suggest that SL can occur implicitly or incidentally. Interestingly, several studies using the related paradigms of artificial grammar learning and serial response time tasks have shown that explicit instructions can aid learning under certain conditions. Within the SL literature, however, very few studies have contrasted incidental and intentional learning conditions. The aim of the present study was to investigate the effect of having prior knowledge of the statistical regularities in the input when undertaking a task of visual sequential SL. Specifically, we compared the degree of SL exhibited by participants who were informed (intentional group) versus those who were uninformed (incidental group) about the presence of embedded triplets within a familiarization stream. Somewhat surprisingly, our results revealed that there were no statistically significant differences (and only a small effect size) in the amount of SL exhibited between the intentional versus the incidental groups. We discuss the ways in which this result can be interpreted and suggest that short presentation times for stimuli in the familiarization stream in our study may have limited the opportunity for explicit learning. This suggestion is in line with recent research revealing a statistically significant difference (and a large effect size) between intentional versus incidental groups using a very similar visual sequential SL task, but with longer presentation times. Finally, we outline a number of directions for future research.

  The present study investigated the brain mechanisms involved during young children’s receptive familiarization with new words, and whether the dynamics of these mechanisms are related to the child’s productive vocabulary size. To this end, we recorded event-related potentials (ERPs) from 20-month-old children in a pseudoword repetition task. Results revealed distinct patterns of repetition effects for children with large and small productive vocabularies. High producers showed evidence of recognizing the novel words already after three presentations, while the low producers needed five presentations to display a recognition effect. The familiarization process was manifested in the modulations of two components, the N200–400 and a later fronto-central component, which appeared to increase in amplitude until a certain level of encoding was reached and then decrease with further repetition. These findings suggest a relation between the onset of the productive vocabulary spurt and the rate of receptive word familiarization.

  Although it is well documented that children undergo a productive vocabulary spurt late in the second year, it is unclear whether this development is accompanied by equally significant advances in receptive word processing. In the present study, we tested an electrophysiological procedure for assessing receptive word learning in young children, and the impact of productive vocabulary size for performance in this task. We found that 20-month-olds with high productive vocabularies displayed an N400 incongruity effect to violations of trained associations between novel words and pictures, whereas 20-month-olds with low productive vocabularies did not. However, both high and low producers showed an N400 effect for common real words paired with an incongruous object. These findings indicate that there may be substantial differences in receptive fast mapping efficiency between typically developing children who have reached a productive vocabulary spurt and typically developing children who have not yet reached this productive spurt.

  Språktilegnelse skjer hovedsakelig gjennom implisitte lærings-mekanismer. For eksempel lærer barn de grammatiske reglene i morsmålet sitt uten at disse reglene noen gang blir forklart for dem. Men hvis vi ikke trenger eksplisitte forklaringer av reglene, hva slags informasjon er det egentlig vi bruker når vi tilegner oss grammatikken i et nytt språk? Og har personer med språkvansker behov for annen informasjon enn personer med normalt språk når de skal lære grammatiske regler? Disse spørsmålene vil jeg se nærmere på i presentasjonen min. Mer spesifikt vil jeg presentere resultater fra en eksperimentell studie som har undersøkt betydningen av variabilitet, antall unike eksemplarer i input, på læring av en kunstig grammatikk.
