前额叶皮层调节执行控制过程，并在整个青春期结构成熟。与这些事件相一致，需要高水平执行控制的前额叶功能可能比那些需要工作记忆但控制力下降的功能成熟得更晚。为了验证这一假设，青少年（9至20岁）完成了非言语工作记忆任务，不同水平的执行要求。研究结果表明，记忆引导的行动，为单一单位的空间信息的发展，直到11至12年。维持和操纵多个空间单位的能力发展到13至15岁。策略性的自我组织发展到16至17岁。在这个年龄段，识别记忆似乎没有发展。前额叶皮层组织的处理水平的影响进行了讨论。
The prefrontal cortex modulates executive control processes and structurally matures throughout adolescence. Consistent with these events, prefrontal functions that demand high levels of executive control may mature later than those that require working memory but decreased control. To test this hypothesis, adolescents (9 to 20 years old) completed nonverbal working memory tasks with varying levels of executive demands. Findings suggest that recall-guided action for single units of spatial information develops until 11 to 12 years. The ability to maintain and manipulate multiple spatial units develops until 13 to 15 years. Strategic self-organization develops until ages 16 to 17 years. Recognition memory did not appear to develop over this age range. Implications for prefrontal cortex organization by level of processing are discussed.
