Language learners' positive and negative emotions were integrated with their social anxiety and their suppression in technology-enhanced learning environments. A total of 878 Chinese English as a Foreign Language (EFL) learners participated in this study. They completed a Computer Technology Integration Questionnaire (CTIQ), an Emotion Regulation Questionnaire (ERQ), a Positive and Negative Affect Scale (PNAS) and a Social Interaction Anxiety Scale (SIAS). Results of SEM analysis indicated that while positive emotions were directly related to the learners' perceptions of technology-enhanced learning environments, their negative emotions adversely predicted their emotion regulation and their perceptions of technology integration. The outcomes confirmed that there were significant and positive relationships between Chinese EFL students' emotion regulation and their perceptions of technology-enhanced learning environments. The findings of the study suggest implications to reduce learners' anxiety and encourage them to use technology in their classrooms. This study is intended to enhance our understanding of positive and negative events in technology-enhanced learning environments.
