研究了基于有声思考协议和潜在语义分析（LSA）的阅读策略评估的可行性。在两项研究中，读者在阅读了两个故事中的特定重点句子后会大声思考。使用LSA来估计读者对重点句子的有声思考协议与为重点句子提供直接因果先行词的故事句子之间的语义相似度。研究1表明，根据基于人的和基于lsa的协议评估，低技能读者的反应与焦点句的语义重叠多于与因果先行句的语义重叠，而熟练读者的反应与这些句子的语义重叠相同。此外，与因果前词的语义重叠程度大于与重点句的语义重叠程度预测了理解测试和阅读技能Nelson-Denny测试的表现。研究2重复了这些发现，并证明语义重叠分数（基于协议）预测了默读故事的回忆。总之，研究结果支持了使用口头协议和LSA开发计算机化评估工具的可行性。
The viability of assessing reading strategies is studied based on think-aloud protocols combined with Latent Semantic Analysis (LSA). Readers in two studies thought aloud after reading specific focal sentences embedded in two stories. LSA was used to estimate the semantic similarity between readers' think-aloud protocols to the focal sentences and sentences in the stories that provided direct causal antecedents to the focal sentences. Study 1 demonstrated that according to human- and LSA-based assessments of the protocols, the responses of less-skilled readers semantically overlapped more with the focal sentences than with the causal antecedent sentences, whereas the responses of skilled readers overlapped with these sentences equally. In addition, the extent that the semantic overlap with causal antecedents was greater than the overlap with the focal sentences predicted performance on comprehension test questions and the Nelson-Denny test of reading skill. Study 2 replicated these findings and also demonstrated that the semantic overlap scores (based on the protocols) predicted recall for stories that were read silently. Together, the findings supported the viability of developing a computerized assessment tool using verbal protocols and LSA.
