In a previous study, Kramer et al. (2019) looked at receptive vocabulary knowledge attrition over summer vacation, found no evidence of attrition using these measures, and called for future research to instead use tests of productive vocabulary knowledge which is more likely to be forgotten. Therefore, in this study we investigate the amount of summer attrition among Japanese university students (N = 81) and any mediation in that attrition attributable to digital paired-associate vocabulary studying, extensive reading, or experience travelling abroad. The results indicate that although there was no significant group difference in pre- and post-test productive vocabulary scores, a small but significant relationship was found between digital paired-associate vocabulary studying and vocabulary test score gains.

During this time students often take a break from studying and focus on working part time jobs, relaxing with friends, or travelling. When removed from the school context rich in foreign language stimulus, students might be expected to lose access to some of the knowledge they have gained, in a process called attrition. The degree of lexical attrition during these breaks is of great concern, and any interventions found to impede this attrition would be valuable for all stakeholders.
