This comprehensive systematic review delves into the increasing prevalence of integrating chatbots into language education. The general objective is to assess the current landscape of knowledge regarding chatbot utilisation and its influence on three crucial elements: students' skills, attitudes, and emotions. Additionally, the review seeks to scrutinise the advantages linked to incorporating chatbots in foreign language teaching, exploring their potential benefits while considering limitations and potential negative impacts on specific skills or user experiences. Consequently, this research offers valuable insights into the application of chatbots in foreign language education, shedding light on their potential advantages and areas that warrant further exploration and enhancement. The integration of chatbots in language learning, despite certain limitations, generally yields positive outcomes and enhances educational results in students' skills. Its characteristics can also influence a language learner's attitude, impacting factors such as motivation, interest, autonomy in learning, and engagement or even their sense of fun. Additionally, chatbots prove to be helpful in creating emotionally positive learning environments and can contribute to boosting students' self-esteem and self-confidence.

In the realm of education, particularly in the domain of second language acquisition, understanding the intricate interplay between emotions and learning processes is a challenging endeavor. This research aims to explore the importance of studying anxiety-related emotions in the learning and teaching of English as a foreign language by conducting a study based on a quantitative methodology. To that end, a 33-item instrument was given to a total of 231 (n=231) university students who learn and use English in class in diverse degrees in the social and health sciences. The results obtained shed light on the negative emotions that students report during their English classes, such as fear, shame, nervousness, or feelings of judgement. However, not all the emotions are negative, since students also feel relaxed and interested. This study offers a new perspective on this topic since it compares different disciplines, underscoring the need to detect trends in different areas and therefore tailor pedagogy to different student profiles and degree programs.
