Traditional measures of language processing and behavior

This chapter provides an overview of traditional experimental methods for measuring language processing and behavior, examining their theoretical foundations, methodological principles, and empirical contributions. The chapter begins by exploring how complexity in linguistic behavior arises from two distinct sources: the formal complexity of grammatical representations and the procedural complexity of realtime processing. Behavioral measures including reaction time and accuracy in tasks such as picture naming, visual-word naming, and lexical decision are then reviewed. Priming and interference paradigms, exploiting, respectively, facilitation and competition to map representational organization and isolate processing stages are also reviewed. The chapter then turns to online measures, such as eye-tracking and ERPs, which extend temporal resolution to the millisecond scale, capturing direct access to neural processes. The concluding theme is the tension between experimental control and ecological validity. Traditional paradigms achieve precision by simplifying contextual, multimodal, and interactive dimensions. While extraordinarily productive, this poses challenges for understanding language as fundamentally grounded in experience. The chapter ends by reflecting on how immersive virtual reality offers a promising path forward, providing experimental control while allowing embodied, situated, and interactive language use that traditional paradigms exclude.
