The focus of this dissertation was to examine how younger and older adults' working memory, inhibitory functioning, and perceptual speed relate to the ability to make syntactic judgements. The study had three primary goals: (1) to measure younger and older adults' on-line grammaticality decisions for two types of complex sentences; (2) to measure younger and older adults' performance on representative working memory, inhibitory functioning, and perceptual speed tasks; and (3) to examine the relations between younger and older adults' on-line grammaticality decisions and performance on the working memory, inhibitory functioning, and perceptual speed tasks. Increased age was associated with poorer performance on measures of working memory, perceptual speed, and inhibitory functioning, but these differences did not affect on-line grammaticality decisions. Older adults averaged longer decision latencies than young adults across sentences types but their latencies weren't differentially affected by the sentence complexity. Age differences in decision times across sentences were not significantly larger for syntactically complex sentence regions compared with syntactically simple regions. The analyses of syntactic processing also suggested that individuals who differ in terms of working memory, perceptual speed, or inhibitory functioning do not differ in terms of on-line grammaticality decisions or in off-line question accuracy. Hierarchical regression was used to assess goal 3. The measures of working memory, perceptual speed, and inhibitory functioning were used to predict on-line grammaticality decisions and off-line question comprehension. The results of the regression analyses suggest that working memory, perceptual speed, and inhibitory functioning are neither good mediators of age-related differences in on-line grammaticality decisions or off-line question answering nor good predictors of language performance in general.
