Abstract

Lexical retrieval is among the most cognitively demanding processes in second language (L2) writing, requiring writers to simultaneously manage form-meaning mappings, orthographic encoding, and discourse coherence. This study examined the cognitive and compositional effects of AI-generated lexical scaffolding (AGLS) on 96 Uzbek EFL university students assigned to unaided writing, AI-scaffolded writing, or dictionary-aided writing conditions. Cognitive load was measured via dual-task reaction time, keystroke logging, and retrospective verbal protocols; writing quality was assessed through lexical diversity, accuracy, and sophistication measures. AGLS significantly reduced cognitive load and improved lexical quality outcomes; however, lower-proficiency writers displayed uncritical adoption patterns, raising concerns about lexical agency and long-term vocabulary development.
