斯卡蒙的生长曲线，即使在此后的80年里，也适用于许多领域。然而，人们不得不怀疑，是否所有的人类特征都包括在这四种模式的增长曲线分类中。到目前为止，斯卡蒙的生长曲线还有待科学验证。在这项研究中，这一评估是通过应用互相关函数来分析折叠其中一条曲线的变化来检查它们的相似性来验证的。在此基础上，利用小波插值方法对量化后的曲线进行互相关处理。用于分析的数据，从1岁到20岁的横断面生长数据被用于由斯卡蒙生长曲线分类的四个属性。这些数据包括脑重(神经型)、胸腺(淋巴型)、睾丸(生殖器型)和肝脏(普通型)。互相关函数用来表示两个波形之间的相似性，互相关函数可以通过一个函数的卷积来计算。在这项研究中，利用小波内插模型(WIM)对斯卡蒙的生长类型进行了区分，根据速度曲线值假设了一个互相关函数。大脑重量和胸腺，以及睾丸和肝脏之间存在着意想不到的相似之处。因此，可以新提出的是，生长曲线类型可以分为神经型、淋巴型和全身型，生殖器型包括在全身型中。生殖器类型、内脏类型和形态类型包括在一般体型中。
The Scammon’s growth curve, even during the 80 years since, has been applied to a number of fields. However, one has to wonder if all human characteristics are included in this 4 pattern growth curve classification. Till now, the Scammon’s growth curve has yet to be subjected to scientific verification. In this study, this assessment was verified by applying a cross-correlation function in analyzing changes from collapsing one of the curves to examine their similarity. Because of that, cross correlation function can then be applied to the quantified curve by Wavelet Interpolation Method. The data utilized for analysis, cross-sectional growth data from age one to 20 was used for the four attributes classified by the Scammon growth curve. This data was comprised of brain weight (neural type), thymus (lymphoid type), testicle (genital type), and liver (general type). A cross correlation function is used to show the similarity between two waveforms, and the cross correlation function may be evaluated by convolving one function. In this study, a cross correlation function was assumed from the velocity curve values found from differentiation using the wavelet interpolation model (WIM) for Scammon’s growth types. There are unanticipated possibilities of similarity between brain weight and thymus, and testicle and liver. What can be newly proposed, therefore, is that growth curve types can be classified as neural, lymphoid, and general body types, with the genital type included in the general body type. The genital type, visceral type, and morphological type are included within the general body type.
