Global virtual teams (GVTs) operate in a globally dispersed work environment , principally relying on communication and information technologies to achieve work tasks. In this work context, using language effectively is crucial. We utilize the cognitive perspective to explain how foreign language use in a GVT influences individual task performance. This study employs (a) cognitive neuroscience of foreign language processing perspective to explain the relationship between foreign language skills and individual task performance; (b) the theory of cognitive load to explain foreign language anxiety as a pathway that further explains how low-level foreign language skill negatively influences individual task performance; and (c) the theory of intelligence to examine the conditional role of cultural intelligence in the mediation process. Utilizing 294 data pairs (collected from GVT members and their respective supervisors) in a multinational offshoring firm, we found support for the mediation process and the conditional influence of the dimensions of cultural intelligence in reducing the negative effect of foreign language anxiety on individual task performance in GVT.
