Abstract Language, emotion, and environment jointly shape how words are processed in real life. This study tested how valence and simulated weather influence bilingual lexical access in virtual reality (VR). Forty Spanish–English bilinguals completed a language-decision task with negative high-arousal and neutral low-arousal words under sunny and rainy conditions. Accuracy was high, with no reliable effects. Reaction times were faster for negative than for neutral words and slower under rain than sun, with no significant language effect. A Weather by Trial Order interaction reflected a practice-related speeding under sun under sunny weather. Valence and weather exerted additive influences, and weather did not modulate language or valence effects. These findings suggest that realistic perceptual load imposes general costs without altering emotional or language-related processing. The study underscores VR’s potential to integrate ecological validity into psycholinguistic paradigms, revealing how intrinsic and extrinsic factors jointly constrain bilingual emotional word processing.
