Missing children represent an important problem for law enforcement. This problem is complicated by the fact that the appearance of children changes as they grow older, making it more difficult to engage the public's help in finding them. One approach that has been recommended is the use of forensic age progression. In forensic age progression, knowledge of typical facial growth patterns are applied to photographs of children from around the time they went missing in order to provide an estimate of the child's current appearance. Age progression may also use photographs of biological relatives on the assumption that the child?s current appearance may be similar to that of their relatives.Age progression is used in about one-third of long-term missing child cases. Unfortunately, prior research has been limited and has produced mixed results. Although it is sensible to apply information about average growth rates to provide an estimate of a child's current appearance, there is also considerable variability in growth patterns between children. This makes accurate prediction in the case of an individual child difficult. The planned research examines factors that may influence the effectiveness of age progressions. During the first year, this research will examine the influence of age range on the effectiveness of age progressions. In Years 2 and 3, the research will examine the impact of presenting multiple age progressions showing what the child may currently look like. The proposed research is one of the first systematic attempts to understand the factors that impact the success of forensic age progression. Knowing more about the factors that lead to successful age progressions will allow practitioners to more create more accurate estimates of the appearance of missing children, resulting in an improved likelihood of recovering missing children.

失踪儿童是执法的重要问题。 由于儿童随着年龄的增长而变化，这一事实使这个问题变得复杂，这使得与公众的帮助更加困难。 建议的一种方法是使用法医年龄进步。在法医年龄的进步中，从大约失踪的时候就将典型面部生长模式的知识应用于儿童的照片，以便对孩子当前的外表进行估计。 年龄进步还可以使用生物亲戚的照片，假设孩子的当前外观可能与他们的亲戚相似。不幸的是，先前的研究受到限制，并产生了不同的结果。 尽管应用有关平均增长率的信息是明智的，以提供对儿童当前外观的估计，但儿童之间的生长模式也有很大的差异。 这使得在一个单个孩子困难的情况下可以准确预测。 计划研究研究了可能影响年龄进步有效性的因素。 在第一年，这项研究将研究年龄范围对年龄进步有效性的影响。 在第2年和第3年中，研究将研究展示多个年龄进度的影响，以显示孩子目前的外观。 拟议的研究是了解影响法医年龄进步成功的因素的第一个系统尝试之一。了解导致成功年龄进步的因素的更多信息将使从业者更加准确地估计失踪儿童的外观，从而提高了康复失踪儿童的可能性。
