为了表征青少年时期的认知成熟，在8至30岁（N = 245）的健康参与者中使用眼动任务测量了处理速度，自愿反应抑制和空间工作记忆。发育进展顺利，最初表现急剧改善，然后在青春期稳定下来。成人水平的成熟表现开始于大约15岁，14岁和19岁的处理速度，反应抑制和工作记忆，分别。虽然加工是独立发展的，但加工速度影响工作记忆的发展，而反应抑制和工作记忆的发展是相互依赖的。这些结果表明，处理速度，自愿反应抑制和工作记忆的成熟，通过童年后期和进入青春期。如何特定的青春期大脑成熟可能支持认知成熟进行了讨论。
To characterize cognitive maturation through adolescence, processing speed, voluntary response suppression, and spatial working memory were measured in 8- to 30-year-old (N = 245) healthy participants using oculomotor tasks. Development progressed with a steep initial improvement in performance followed by stabilization in adolescence. Adult-level mature performance began at approximately 15, 14, and 19 years of age for processing speed, response inhibition, and working memory, respectively. Although processes developed independently, processing speed influenced the development of working memory whereas the development of response suppression and working memory were interdependent. These results indicate that processing speed, voluntary response suppression, and working memory mature through late childhood and into adolescence. How brain maturation specific to adolescence may support cognitive maturation is discussed.
