Background Aphasia is a language disorder resulting from brain damage that disrupts language comprehension and production, emphasizing the need for effective diagnostic and therapeutic tools.Aims This narrative review examines how eye-tracking technology has been used to investigate language production deficits in people with aphasia (PWA). It seeks to identify emerging research trends, assess the contributions of eye-tracking to understanding language production processes, and explore the technology’s potential clinical relevance in aphasiology.Methods and Procedures A comprehensive search of four databases was conducted using the key terms “aphasia”, “eye-tracking”, and “language production”, as well as their combinations, covering the period from January 2015 to January 2025. The initial search yielded 95 articles. After screening titles and abstracts according to predefined inclusion and exclusion criteria, 20 papers were selected for further review. A subsequent full-text review excluded articles not explicitly focused on language production in PWA, resulting in six studies for detailed appraisal. These studies specifically explored the application of eye-tracking to language production processes in PWA.Outcomes and Results The reviewed studies demonstrate that eye-tracking can elucidate the linguistic mechanisms underlying language production deficits in PWA. Eye movement and eye fixation patterns in PWA offer insight into how aphasia disrupts various stages of language production.Conclusions Our findings suggest that eye-tracking provides valuable insights into the complex processes disrupted by aphasia. Thus, eye-tracking device can represent a promising avenue for enhancing diagnostic accuracy and informing therapeutic interventions for PWA. This review also underscores the need for further research to expand our understanding and application of eye-tracking technology in aphasiology, paving the way for advancements in both theoretical knowledge and clinical practice.
