| Popis: | Objectives: Lexical access problems are one of the limitations observed in children with developmental language disorders during the initial years of schooling. Semantic context has a powerful influence on lexical access. The cross-modal visual-auditory picture-word interference paradigm is a method for studying adults and children's lexical access. Because few studies have examined lexical access in Persian-speaking children, the present study aimed to investigate the effect of different semantic contexts on lexical access in children with and without developmental language disorder. Methods: In this experimental study, 20 children aged 7-9 years with developmental language disorders and 20 age-matched peers were recruited according to the inclusion and exclusion criteria. At first, the picture-word interference paradigm was prepared. In so doing, 16 common pictures of objects paired with four auditory interfering words (related verb, related noun, unrelated verb, and unrelated noun) were presented to the children in a silent condition to determine their naming accuracy and latency. The DMDX software calculated the naming latency. The percentage of correct names also calculated naming accuracy. Results: Naming latencies were significantly faster in children without language disorders (P≤0.05). In addition, a reliable interference effect was found. According to the results, naming latencies were significantly faster for related verb distractors than unrelated verbs and related noun distractors (P |
