A comprehensive overview of neuropsychiatric symptoms in adolescents with 22q11.2 deletion syndrome.

Background: The 22q11.2 deletion syndrome (22q11DS) is associated with a variety of neuropsychiatric outcomes that vary across deletion carriers. We adopted a dimensional approach to provide a comprehensive overview of neuropsychiatric symptom expression in adolescents with 22q11DS and further our understanding of the observed phenotypical heterogeneity.

Speech sound development of young Dutch children with a developmental language disorder: A complex matter.

Background: Approximately 50% of all young children with a developmental language disorder (DLD) also have problems with speech production. Research on speech sound development and clinical diagnostics of speech production difficulties focuses mostly on accuracy; it relates children's phonological realizations to adult models. Contrarily to these relational analyses, independent analyses indicate the sounds and structures children produce irrespective of accuracy.

Dolphin CONTINUE: a multi-center randomized controlled trial to assess the effect of a nutritional intervention on brain development and long-term outcome in infants born before 30 weeks of gestation.

Background: Preterm born infants are at risk for brain injury and subsequent developmental delay. Treatment options are limited, but optimizing postnatal nutrition may improve brain- and neurodevelopment in these infants. In pre-clinical animal models, combined supplementation of docosahexaenoic acid (DHA), choline, and uridine-5-monophosphate (UMP) have shown to support neuronal membrane formation.

Communication in Daily Life of Children With Developmental Language Disorder: Parents' and Teachers' Perspectives.

Purpose: This study explores limitations in communication in daily life of children with developmental language disorder (DLD) from their parents' perspective as well as communicative abilities and social functioning in the classroom from their teacher's perspective. Furthermore, differences between children with mixed receptive-expressive disorder and children with expressive-only disorder in communication in daily life and social functioning are studied.

Method: Data were collected through questionnaires completed by parents and teachers of children (5-6 years old) who attended schools for special education for DLD.

What risk factors for Developmental Language Disorder can tell us about the neurobiological mechanisms of language development.

Language is a complex multidimensional cognitive system that is connected to many neurocognitive capacities. The development of language is therefore strongly intertwined with the development of these capacities and their neurobiological substrates. Consequently, language problems, for example those of children with Developmental Language Disorder (DLD), are explained by a variety of etiological pathways and each of these pathways will be associated with specific risk factors.

Nonverbal Executive Functioning in Relation to Vocabulary and Morphosyntax in Preschool Children With and Without Developmental Language Disorder.

Purpose: Developmental language disorder (DLD) is characterized by persistent and unexplained difficulties in language development. Accumulating evidence shows that children with DLD also present with deficits in other cognitive domains, such as executive functioning (EF). There is an ongoing debate on whether exclusively verbal EF abilities are impaired in children with DLD or whether nonverbal EF is also impaired, and whether these EF impairments are related to their language difficulties.

Behaviors related to autism spectrum disorder in children with developmental language disorder and children with 22q11.2 deletion syndrome.

Background And Aim: Children with Developmental Language Disorder (DLD) are at an increased risk to develop behaviors associated with Autism Spectrum Disorder (ASD). The relationship between early language difficulties and the occurrence of ASD-related behaviors in DLD is poorly understood. One factor that may hinder progress in understanding this relationship is the etiological heterogeneity of DLD.

Executive functioning in preschoolers with 22q11.2 deletion syndrome and the impact of congenital heart defects.

Background: Executive functioning (EF) is an umbrella term for various cognitive functions that play a role in monitoring and planning to effectuate goal-directed behavior. The 22q11.2 deletion syndrome (22q11DS), the most common microdeletion syndrome, is associated with a multitude of both somatic and cognitive symptoms, including EF impairments in school-age and adolescence.

[Attention for language; atypical language development and psychiatric symptoms in children].

Background: Children with a neurodevelopmental or psychiatric disorder often have language difficulties. A large group of children has severely impaired language learning abilities in the absence of a clear cause. These children have developmental language disorder (DLD).

[Taal: een introductie].

Background: This special issue discusses the roles and functions of language in psychiatric practice from different perspectives. As an introduction, we discuss the phenomenon ‘language’ as an object of scientific investigation.

Aim: To give a brief introduction to this theme issue.

Natural Language Processing Markers for Psychosis and Other Psychiatric Disorders: Emerging Themes and Research Agenda From a Cross-Linguistic Workshop.

This workshop summary on natural language processing (NLP) markers for psychosis and other psychiatric disorders presents some of the clinical and research issues that NLP markers might address and some of the activities needed to move in that direction. We propose that the optimal development of NLP markers would occur in the context of research efforts to map out the underlying mechanisms of psychosis and other disorders. In this workshop, we identified some of the challenges to be addressed in developing and implementing NLP markers-based Clinical Decision Support Systems (CDSSs) in psychiatric practice, especially with respect to psychosis.

Robustness of the cognitive gains in 7-month-old bilingual infants: A close multi-center replication of Kovács and Mehler (2009).

We present an exact replication of Experiment 2 from Kovács and Mehler's 2009 study, which showed that 7-month-old infants who are raised bilingually exhibit a cognitive advantage. In the experiment, a sound cue, following an AAB or ABB pattern, predicted the appearance of a visual stimulus on the screen. The stimulus appeared on one side of the screen for nine trials and then switched to the other side.

The Language Profile of Preschool Children With 22q11.2 Deletion Syndrome and the Relationship With Speech Intelligibility.

Purpose: Young children with 22q11.2 deletion syndrome (22q11DS) often have impaired language development and poor speech intelligibility. Here, we report a comprehensive overview of standardized language assessment in a relatively large sample of preschool-aged children with 22q11DS.

Language gains in 4-6-year-old children with developmental language disorder and the relation with language profile, severity, multilingualism and non-verbal cognition.

Background: Early and effective treatment for children with developmental language disorder (DLD) is important. Although a growing body of research shows the effects of interventions at the group level, clinicians observe large individual differences in language growth, and differences in outcomes across language domains. A systematic understanding of how child characteristics contribute to changes in language skills is still lacking.

Primary teachers' attitudes towards using new technology and stimulating higher-order thinking in students: A profile analysis.

Critical thinking, creative thinking, problem solving and other so-called higher-order thinking skills are regarded as crucial for students to develop. Research shows that technology can be used as a tool to stimulate students' higher-order thinking skills. However, most teachers rarely use new technology to stimulate students to engage in higher-order thinking.

Disentangling the Grammar of 3- to 6-Year-Old Dutch Children With a Developmental Language Disorder.

Purpose: Children with a developmental language disorder (DLD) are often delayed in their grammatical development. This is suggested to be the most important characteristic and clinical marker of DLD. However, it is unknown if this assumption is valid for young children, in the earliest stages of grammatical development.

Characterizing speech heterogeneity in schizophrenia-spectrum disorders.

Schizophrenia-spectrum disorders (SSD) are highly heterogeneous in risk factors, symptom characteristics, and disease course outcome. Although speech anomalies have long been recognized as a core symptom of SSD, speech markers are an unexplored source of symptom heterogeneity that may be informative in recognizing relevant subtypes. This study investigated speech heterogeneity and its relation to clinical characteristics in a large sample of patients with SSD and healthy controls.

Robustness of the rule-learning effect in 7-month-old infants: A close, multicenter replication of Marcus et al. (1999).

We conducted a close replication of the seminal work by Marcus and colleagues from 1999, which showed that after a brief auditory exposure phase, 7-month-old infants were able to learn and generalize a rule to novel syllables not previously present in the exposure phase. This work became the foundation for the theoretical framework by which we assume that infants are able to learn abstract representations and generalize linguistic rules. While some extensions on the original work have shown evidence of rule learning, the outcomes are mixed, and an exact replication of Marcus et al.

Fast but Not Furious. When Sped Up Bit Rate of Information Drives Rule Induction.

The language abilities of young and adult learners range from memorizing specific items to finding statistical regularities between them () and generalizing rules to novel instances (). Both external factors, such as input variability, and internal factors, such as cognitive limitations, have been shown to drive these abilities. However, the exact dynamics between these factors and circumstances under which rule induction emerges remain largely underspecified.

Narrative comprehension and production abilities of children with 22q11.2 deletion syndrome.

Background: The 22q11.2 Deletion Syndrome (22q11DS) is associated with language deficits and weak intellectual functioning. In other clinical groups, linguistic and cognitive difficulties have been associated with impaired acquisition of narrative abilities.

Acoustic speech markers for schizophrenia-spectrum disorders: a diagnostic and symptom-recognition tool.

Background: Clinicians routinely use impressions of speech as an element of mental status examination. In schizophrenia-spectrum disorders, descriptions of speech are used to assess the severity of psychotic symptoms. In the current study, we assessed the diagnostic value of acoustic speech parameters in schizophrenia-spectrum disorders, as well as its value in recognizing positive and negative symptoms.

Negative content in auditory verbal hallucinations: a natural language processing approach.

Introduction: Negative content of auditory verbal hallucinations (AVH) is a strong predictor of distress and impairment. This paper quantifies emotional voice-content in order to explore both subjective (i.e.

Reduced brain activation during spoken language processing in children with developmental language disorder and children with 22q11.2 deletion syndrome.

Language difficulties of children with Developmental Language Disorder (DLD) have been associated with multiple underlying factors and are still poorly understood. One way of investigating the mechanisms of DLD language problems is to compare language-related brain activation patterns of children with DLD to those of a population with similar language difficulties and a uniform etiology. Children with 22q11.

The contribution of individual differences in statistical learning to reading and spelling performance in children with and without dyslexia.

Using an individual differences approach in children with and without dyslexia, this study investigated the hypothesized relationship between statistical learning ability and literacy (reading and spelling) skills. We examined the clinical relevance of statistical learning (serial reaction time and visual statistical learning tasks) by controlling for potential confounds at the participant level (e.g.
