| Research Abstract |
The ability to understand speakers' intentions from affective speech was investigated for typically(normally)-developing elementary school children and those with communication disorders. The percent correct of intention judgment for the normally-developing children was the highest for the congruent single-phrases and the lowest for the incongruent narrative phrases with intermediate scores for the incongruent single-phrases and the narrative metaphor phrases. The children showed significantly different scores depending on their disorders. The results of neuro-cognitive analyses suggest that understanding speakers' intentions depends on four major information processing systems in the brain including the mirror neuron system, the mentalizing system and linguistic inference system.
