Abstract

Previous studies have reported the importance of the precuneus in mediating metacognition and the prefrontal cortex in decision-making tasks. However, the mechanisms underlying metacognition remain to be fully elucidated. N-acetyl aspartate/creatine + phosphocreatine (NAA/Cr + PCr) is a putative neuronal marker level, which has been used in cognitive disorders. Long echo time proton magnetic resonance spectroscopy was used to further explore the metabolic correlates of metacognition. Metacognition was based on a self-reported questionnaire of nursing students. Magnetic resonance spectra of the bilateral precuneus and medial prefrontal cortex were recorded. A significant positive correlation was discovered between the total metacognitive score and academic performance (p = .007). The precuneus NAA/Cr + PCr ratios corresponded to metacognitive ability. Moreover, the correlation between precuneus NAA/Cr + PCr ratios and metacognitive ability was established for the right and not for the left precuneus. These findings further indicated that the right precuneal region plays an important role in metacognition. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

利用磁共振波谱法探索元认知能力。

先前的研究已经报道了楔前叶在调节元认知和前额叶皮层在决策任务中的重要性。然而，元认知的机制仍有待充分阐明。n -乙酰天冬氨酸/肌酸+磷酸肌酸(NAA/Cr + PCr)是一个公认的神经元标志物水平，已被用于认知障碍。利用长回声时间质子磁共振波谱进一步探讨元认知的代谢相关因素。元认知以护生自述问卷为基础。记录双侧楔前叶和内侧前额叶皮层的磁共振谱。元认知总分与学业成绩呈显著正相关(p = .007)。楔前叶NAA/Cr + PCr比值与元认知能力相关。此外，右楔前叶NAA/Cr + PCr比值与元认知能力存在相关性，而左楔前叶无相关性。这些发现进一步表明，右楔前区在元认知中起着重要的作用。(PsycInfo数据库记录(c) 2023 APA，版权所有)。
