We compared right-handed familial dextral (FS2) and familial sinistral (FS1) participants who were aged either 10–13 years (children) or 18–23 years (adults). In word probe and associative probe tasks, FS1 adults responded faster than all other groups and FS1 children responded more slowly than all other groups. In the word probe task, only the FS2 adults showed a significant effect of the serial position of the target word. We interpret these differences to support an analysis-by-synthesis model of comprehension in which individuals who differ in familial handedness and age emphasize different linguistic representations during comprehension. In general, FS1 individuals focus on words and meaning, while FS2 individuals focus on syntactic representations. In FS1 individuals, age-related experiences with language produce a shift in responding from compositional meaning to words and their associations. In FS2 individuals, age-related experiences with language produce a shift toward responding based more on detailed syntactic representations, including the serial order of words and possibly the structural roles of clauses.
