The aim of this longitudinal study is to evaluate 3 views on the relationship between nonword repetition and vocabulary: (i) the storage-based view that considers nonword repetition, a measure of phonological storage, as the driving force behind vocabulary development, (ii) the lexical restructuring view that considers improvements in nonword repetition as the result of vocabulary growth, and (iii) the "combined" view that assumes that both storage-based learning and lexical restructuring play a role, resulting in reciprocal relationships between nonword repetition and vocabulary during language development. Data are analyzed from 471 monolingual Dutch children who performed tasks assessing nonword repetition and vocabulary at yearly intervals, from ages 2 to 5. Latent Change Score (LCS) modeling of Item Response Theory-scaled scores was used to investigate the relationships between nonword repetition and vocabulary growth over time. Additionally, the statistical techniques used in earlier work-cross-lagged and latent growth modeling-were applied to see whether the results changed as a function of the analytical technique used. Results from a bivariate LCS model showed positive reciprocal influences from nonword repetition on vocabulary between 2 and 5 years. Such positive cross-influences also emerged from the cross-lagged and latent growth models. Predictive relationships from vocabulary to nonword repetition were stronger than vice versa. These results indicate that both storage-based learning and lexical restructuring play a role in vocabulary learning, at least in early stages of language development, with the clearest support found for lexical restructuring.

Effects of immune modulatory treatment on language and psychiatric profile in patients with electrical status epilepticus in sleep (ESES).

Electrical status epilepticus in sleep (ESES) is an electrographic pattern associated with cognitive impairment. Our study aimed to prospectively evaluate the psychiatric findings and language skills in patients diagnosed with ESES and to determine the immune modulatory treatment-responsive subgroups. We assessed the patients for psychiatric features and language skills at the baseline and 12 months after.

Background: The defective spoken output of persons with aphasia has anomia as a main clinical manifestation. Improving anomia is therefore a main goal of any language treatment.
Aim: This study assessed the effectiveness of a novel, 2-week, rehabilitation protocol (PHOLEXSEM), focused on PHonological, SEmantic, and LExical deficits, aiming at improving lexical retrieval, and, generally, spoken output.
The Impact of Executive Functions and Musicality on Speech Auditory-Motor Synchronization in Adults Who Stutter.

Purpose: Stuttering is a neurodevelopmental disorder that disrupts the timing and rhythmic flow of speech production. There is growing evidence indicating that abnormal interactions between the auditory and motor cortices contribute to the development of stuttering. The present study investigated speech auditory-motor synchronization in stuttering adults and the influential factors behind it as compared to individuals without stuttering.

Electronic address:
Based on historic observations that children with reading disabilities were disproportionately both male and non-right-handed, and that early life insults of the left hemisphere were more frequent in boys and non-right-handed children, it was proposed that early focal neuronal injury disrupts typical patterns of motor hand and language dominance and in the process produces developmental dyslexia. To date, these theories remain controversial. We revisited these earliest theories in a contemporary manner, investigating demographics associated with reading disability, and in a subgroup with and without reading disability, compared structural imaging as well as patterns of activity during tasks of verb generation and non-word repetition using magnetoencephalography source imaging.

Article Synopsis
- This study investigates how language-specific features affect primary progressive aphasia (PPA) symptoms in Italian and English speakers, diverging from the traditionally English-focused research.
- A comparison was made between 106 Italian speakers and 166 English speakers with various PPA syndromes, highlighting differences in demographic factors and symptom profiles.
- Results showed significant variations between the cohorts, with English speakers having a higher proportion of nonfluent/agrammatic PPA cases and different patterns of language comprehension and production issues compared to Italian speakers.
