Backgrounds: The relationship between linguistic difficulties and cognitive impairments in children with developmental language disorders (DLDs) is receiving growing interest in international research. Executive functions (EF) appear to be weak in these children. The current investigation aims at exploring the relationship between difficulties in two components of EF (i.e., updating and inhibition) and the linguistic and narrative skills of 16 DLD preschoolers matched with 24 typically developing peers. Methods: Updating skills were tested by administering the forward and backward digit recall subtests of the Wechsler Scales, while children’s inhibition abilities were assessed by completion of Developmental Neuropsychological Assessment (NEPSY-II) inhibition tasks. Information on the linguistic skills of the participants was collected through a set of subtests included in the Batteria per la Valutazione del Linguaggio in bambini dai 4 ai 12 anni (Batteria per la Valutazione del Linguaggio; BVL_4-12), assessing articulatory and phonological discrimination skills, lexical production/comprehension, grammatical production/comprehension, and narrative production skills. Results: Findings revealed that DLD children performed significantly lower than their peers on both updating and inhibitory tasks. Linguistic difficulties were found in the DLD group on articulatory/phonological skills, grammatical production/comprehension, and lexical informativeness on narrative production. Measures of EF correlated with linguistic and narrative measures. Conclusion: The current study confirms a significant association between DLD’s performances on EF and displayed linguistic skills, suggesting the need to include the assessment of executive functions to target early intervention rehabilitation programs for children with DLDs.

This paper describes the complex phonological patterns of one Slovenian-speaking girl with protracted phonological development who received phonological intervention. At 4;6, the child’s word length, stress and vowels were age-level, but she showed reduced match levels (accuracy) for syllable structure and consonants. Unusual constraints on word position and sequences, particularly concerning fricatives and stops, resulted in many assimilations, reduplications and metatheses. Addressing these constraints in the first intervention period (to 4;9) led to higher overall accuracy and a transition from less typical to more typical mismatches (“errors”), e.g., sibilant grooving (stridency) and rhotic production as singletons and in clusters. The profile focuses on that initial pre- and post-treatment period, giving a brief overview of the follow-up intervention and outcomes and reflecting on implications for future research and clinical practice. 11 The abstract is available in Slovenian language (see Supplementary material).
