Theoretical Disunity in Second Language Acquisition (SLA) 30 3.2. When Knowledge Is Incomplete: The Role of Theory 33 3.3. A Cognitive–Interactionist Theory of ISLA: Problems and Explanations 36 P1. Purely incidental and implicit child L1A is overwhelmingly successful 36 P2. Purely incidental and implicit adult L2A is highly variable and largely unsuccessful 37 E1. Adult SLA is maturationally constrained 38 E2. Adults, so defi ned, are partially ???disabled??? language learners 41 P3. Some classes of linguistic features in adult SLA are fragile 43 E3. Implicit learning is still the default learning mechanism 43 E4. Explicit learning (including focal attention) is required to improve implicit processing in adult SLA but is constrained 49 E5. Attention is critical, at two levels 51 E6. The interaction hypothesis 52 E7. The role of negative feedback, including recasts 54 P4. Success and failure in adult SLA vary among and within individuals 57 E8. Individual differences, especially input sensitivity, and linguistic differences, especially perceptual saliency, are responsible for variability in, and within, ultimate L2 attainment 58 3.4.
