Understanding the constraints, including biological ones, that may influence mathematical development is of great importance because math ability is a key predictor of career success, income and even psychological well-being. While research in developmental cognitive neuroscience of mathematics has extensively studied the key functional regions for processing numbers, particularly the horizontal segment of intraparietal sulcus (HIPS), few studies have investigated the effects of early cerebral constraints on later mathematical abilities. In this pre-registered study, we investigated whether variability of the sulcal pattern of the HIPS, a qualitative feature of the brain determined in-utero and not affected by brain maturation and learning, accounts for individual difference in symbolic and non-symbolic number abilities. Seventy-seven typically developing school-aged children and 21 young adults participated in our study. We found that the HIPS sulcal pattern, (a) explains part of the variance in participant’s symbolic number comparison and math fluency abilities, and (b) that this association between HIPS sulcal pattern and symbolic number abilities was found to be stable from childhood to young adulthood. However, (c) we did not find an association between participant’s non-symbolic number abilities and HIPS sulcal morphology. Our findings suggest that early cerebral constraints may influence individual difference in math abilities, in addition to the well-established neuroplastic factors.

顶内沟的沟与象征性而非象征性的数字技能有关

了解可能影响数学发展的限制因素,包括生物学限制因素非常重要,因为数学能力是职业成功、收入甚至心理健康的关键预测因素。虽然数学发展认知神经科学的研究已经广泛研究了处理数字的关键功能区域,特别是顶内沟 (HIPS) 的水平段,但很少有研究调查早期大脑限制对后期数学能力的影响。在这项预先注册的研究中,我们调查了 HIPS 的沟模式的变异性,这是一种在子宫内决定的大脑的定性特征,不受大脑成熟和学习的影响,是否可以解释符号和非符号数字能力的个体差异. 77 名典型的学龄儿童和 21 名年轻人参加了我们的研究。我们发现 HIPS 沟模式,(a) 解释了参与者的符号数字比较和数学流畅能力的部分差异,以及 (b) 发现 HIPS 沟模式和符号数字能力之间的这种关联从童年到青年是稳定的成年。然而,(c)我们没有发现参与者的非符号数字能力与 HIPS 沟形态之间存在关联。我们的研究结果表明,除了公认的神经可塑性因素之外,早期的大脑限制可能会影响数学能力的个体差异。(a) 解释了参与者的符号数字比较和数学流畅能力的部分差异,以及 (b) 发现 HIPS 沟模式和符号数字能力之间的这种关联从童年到青年时期是稳定的。然而,(c)我们没有发现参与者的非符号数字能力与 HIPS 沟形态之间存在关联。我们的研究结果表明,除了公认的神经可塑性因素之外,早期的大脑限制可能会影响数学能力的个体差异。(a) 解释了参与者的符号数字比较和数学流畅能力的部分差异,以及 (b) 发现 HIPS 沟模式和符号数字能力之间的这种关联从童年到青年时期是稳定的。然而,(c)我们没有发现参与者的非符号数字能力与 HIPS 沟形态之间存在关联。我们的研究结果表明,除了公认的神经可塑性因素之外,早期的大脑限制可能会影响数学能力的个体差异。
