L2 Lexical Attrition and Vocabulary Re-learning in Three L1 English L2 Japanese Children

In this paper I review the evidence for the role of age in affecting second language attrition, and find it strongly supports a large difference in attrition around a breakpoint of age 8. I propose a Dynamic Attrition Model which posits that attrition sets in immediately upon the loss of contact with a language but the speed of loss differs depending on age. Three children who began their incubation periods at age 6, 8 and 10 are examined when they are re-exposed to Japanese 6 years later. All children showed strong savings rates but large losses to their L2 Japanese.
