Making alliterative collocations memorable

Abstract Collocations are a key component of second language (L2) mastery. Yet, their acquisition poses major challenges to L2 learners. One potential solution to this difficulty is employing the mnemonic effect of alliteration (e.g., pr ofessional pr actice ). In the present study, 230 Japanese EFL university students learnt alliterative and non-alliterative collocations (e.g., p rimary p urpose vs. primary care ) under vocalised and non-vocalised conditions in a within-subject design. Vocalisation frequencies were operationalised (none, once, three, and five times) over four weeks to examine potential differences across repetition frequencies. Immediate and delayed productive recall post-test assessed collocational uptake. Results showed that alliterative collocations yielded greater gains than non-alliterative ones when vocalisation was involved, suggesting a conditional benefit of vocalisation in combination with phonological salience. A modest advantage was observed in the three-times vocalisation condition in the immediate post-test; however, it was not reliably maintained at the delayed post-test.
