Objectives: The purpose of this study was to investigate the bi-directions between long distance stages by comparing the semantic priming effect on children with and without speech sound disorders.
Methods: The study subjects were 15 typically developing peers (TD group), 15 children with pure speech sound disorders (pure SSD group) and 10 children with speech sound disorders with language disorder (SSD+LD group) from 3 to 5 years of age. The lexical switching task consisted of naming two pictures. A context picture (priming stimulus) was sometimes replaced with a target picture (target stimulus); the picture names were related or unrelated in meaning. The authors measured response time, response accuracy, and error type rates.
Results: The response time was not significantly different between the pure SSD group and the TD group in semantic conditions. However, response accuracy was significantly different between the pure SSD group and the TD group. The response accuracy of the SSD+LD group was not significantly different between semantic and non-semantic conditions. As a result of the error analysis, the SSD+LD group showed significantly more ‘formal’ errors than the pure SSD group, whereas the pure SSD group showed significantly more ‘unrelated’ errors than the SSD+LD group.
Conclusion: This study demonstrated that bi-directional interaction of each stage decayed semantic priming effect. The findings suggest that studies on communication disorders should be conducted comprehensively in a broad range of areas, not in specific areas.
