Optimizing the study of vocabulary words for high-stakes tests such as the SAT or GRE prep can beproblematic, given that many words are semantically,orthographically, or phonologically confusable. Companiesmarketing test preparation programs make multiplerecommendations, such as clustering words on some basis,but little research has been carried out to examine what thatbasis should be. Across two experiments, we compare theefficacy of different types of clustering—categorical,alphabetical, and confusable--for the learning ofsemantically related words (Experiment 1) and confusablewords (Experiment 2). We demonstrate that, in contrastto most learners’ intuitions, an alphabetical sequence yieldssuperior learning.
