本研究使用潜在语义分析（LSA）来分析参与者阅读说明性段落时收集的口头协议。在这项研究中，参与者被要求在阅读两篇科学文本的每个句子后写出他们的想法。使用 LSA 计算协议与当前句子和先前因果句子之间的语义相似度。由 LSA 生成的余弦表示的相似性大小可预测理解问题和 Nelson-Denny 理解测试的表现。结果在之前的研究和测试开发的背景下进行了讨论。
The present study used latent semantic analysis (LSA) to analyze verbal protocols that were collected while participants read expository passages. In the study, participants were asked to type their thoughts after reading each sentence of 2 scientific texts. The semantic similarity between the protocols and the current sentence and prior causal sentences was computed using LSA. The magnitude of the similarity, as expressed by LSA-generated cosines, predicted performance on comprehension questions and the Nelson-Denny test of comprehension. The results were discussed in the context of previous research and test development.
