Much research has shown that experts possess superior memory in their domain of expertise. This memory benefit has been proposed to be the result of various encoding mechanisms, such as chunking and differentiation. Another potential encoding mechanism that is associated with memory is event segmentation, which is the process by which people parse continuous information into meaningful, discrete units. Previous research has found evidence that segmentation, to some extent, is affected by top-down processing. To date, few studies have investigated the influence of expertise on segmentation, and questions about expertise, segmentation ability, and their impact on memory remain. The goal of the current study was to investigate the influence of expertise on segmentation and memory ability for two different domains: basketball and Overwatch. Participants with high and low knowledge for basketball and with low knowledge for Overwatch viewed and segmented videos at coarse and fine grains, then completed memory tests. Differences in segmentation ability and memory were present between experts and control novices, specifically for the basketball videos; however, experts’ segmentation only predicted memory for activities for which knowledge was lacking. Overall, this research suggests that experts’ superior memory is not due to their segmentation ability and contributes to a growing body of literature showing evidence supporting conceptual effects on segmentation.

许多研究表明，专家在他们的专业领域拥有卓越的记忆力。这种内存优势被认为是各种编码机制的结果，例如分块和差异化。另一种与记忆相关的潜在编码机制是事件分割，这是人们将连续信息解析为有意义的离散单元的过程。先前的研究已经发现证据表明，分割在某种程度上受到自上而下处理的影响。迄今为止，很少有研究调查专业知识对分割的影响，关于专业知识、分割能力及其对记忆的影响的问题仍然存在。当前研究的目标是调查专业知识对篮球和守望先锋两个不同领域的分割和记忆能力的影响。篮球知识高低和守望先锋知识低的参与者观看和分割粗粒度和细粒度的视频，然后完成记忆测试。专家和对照新手在分割能力和记忆方面存在差异，尤其是篮球视频；然而，专家的分割只能预测缺乏知识的活动的记忆。总体而言，这项研究表明专家的卓越记忆力并不是由于他们的分割能力，而是有助于越来越多的文献显示支持概念对分割的影响的证据。专家和对照新手在分割能力和记忆方面存在差异，尤其是篮球视频；然而，专家的分割只能预测缺乏知识的活动的记忆。总体而言，这项研究表明专家的卓越记忆力并不是由于他们的分割能力，而是有助于越来越多的文献显示支持概念对分割的影响的证据。专家和对照新手在分割能力和记忆方面存在差异，尤其是篮球视频；然而，专家的分割只能预测缺乏知识的活动的记忆。总体而言，这项研究表明专家的卓越记忆力并不是由于他们的分割能力，而是有助于越来越多的文献显示支持概念对分割的影响的证据。
