This study aims to identify the phonological error patterns of normally developing children who speak colloquial Jordanian Arabic dialect and to provide normative data for the age of suppression for each phonological error pattern. One hundred fifty-four normally developing children (68 females and 86 males) ranging from 3 to 6.5 years were…

Background: The majority of children with cerebral palsy (CP) experience challenges in functional communication from a young age. A pivotal aspect of functional communication is language comprehension. A variety of classification systems and questionnaires are available to classify and describe functional communication skills in children with CP.…

A good deal of research purports that bilingualism has a positive effect on some aspects of cognitive functioning. However, this effect is not consistent, and little research examines trajectories of cognitive skill development in bilingual children. Moreover, it remains unclear whether different types of bilingualism impact how cognitive…

Testing of previously studied information potentiates subsequent learning of new information, a phenomenon referred to as the "forward testing effect" (FTE). The current study aimed to investigate the developmental trajectory of the FTE and whether the reset-of-encoding process contributes to the FTE. Younger children, older children,…

The appropriate selection of standardized tests is integral to establishing an accurate early diagnosis and providing timely treatment to optimize language outcomes in young children. However, clinicians sometimes utilize tests that are not validated for this specific purpose. This applied dissertation was designed to investigate the validity of…

Autism Spectrum Disorder (ASD) and epilepsy represent a comorbidity that negatively influences the proper development of linguistic competencies, particularly in receptive language, in the pediatric population. This group displays impairments in the auditory comprehension of both simple and complex grammatical structures, significantly limiting…

For proper assessment, diagnosis, and treatment of language disorders in Mandarin children, it is important to have measures that closely track the course of normal development. The current study uses a large collection of spontaneous conversational language samples to track the developmental course of five language measures: mean length of…

Many words are associated with more than a single meaning. Words are sometimes "ambiguous," applying to unrelated meanings, but the majority of frequent words are "polysemous" in that they apply to multiple "related" meanings. In a preregistered design that included 2 tasks, we tested adults' and 4.5- to 7-year-old…

This study investigated endogenous and exogenous predictors of early literacy in Turkish-speaking children. Whether children's language and working memory performances (as the endogenous factors) and home literacy environment (as the exogenous factor) in the beginning of kindergarten predict the children's current and year-end early literacy…

We evaluated the efficacy of Early Language Comprehension Individualized Instruction (ELCII), a supplemental computer-based early language comprehension intervention, in improving kindergarten students' inference making performance. In Study 1, students completed ELCII modules over nine weeks, whereas a business-as-usual control group engaged in…

Researchers largely rely on child language and literacy measures to determine the effectiveness of interventions for Latino dual language learners. However, some of these measures may miss certain strengths of these students. This study identified two unstandardized language and literacy tasks (IDELA food and animal vocabulary and personal…

In this study, a narrative-based language intervention (NBLI) is evaluated in children with HL based on selected narrative outcome measures important for telling and retelling stories. Nine Danish children with slight to severe sensorineural HL in the age range of 4;11-8;8 years participated. The study had a single-arm early efficacy design. The…

Purpose: Assessing early language skills through parental report is a cost-effective way to screen for language delays when resources are scarce. A pan-Arabic lexeme approach was tested by extending the Egyptian adaptation of the MacArthur-Bates Communicative Development Inventory (CDI) to Jordan and Palestine in infants aged 8-30 months (Arabic…

The current study examined the effect of speaker variability on children's cross-situational word learning (XSWL). The study also examined the role of bilingual experience and sustained attention. Forty English monolingual children and 40 Spanish-English bilingual children ages 4-7 completed a XSWL task in a Single Speaker Condition and a Multiple…

The Sentence Structure sub-test (SST) of the Clinical Evaluation of Language Fundamentals (CELF) aims to "measure the acquisition of grammatical (structural) rules at the sentence level". Although originally designed for clinical practice with monolingual children, components of the CELF, such as the SST, are often used to inform…
