Auditory selective attention (ASA) refers to the mental ability to resist distractors and to focus on a specific sound in a complex acoustic environment. Revealing the factors that affect people\u2019s ASA\u00a0can help to improve student\u2019s learning environment. Thus, studies have been\u00a0conducted both in\u00a0real life and virtual reality (VR) environments. This study aimed to make a further step to the real\u00a0life, thus short acoustic stimuli used by a previous study were extend to complex acoustic stimuli,\u00a0and the impact of different variables on the ASA of the participants were analyzed. The complex\u00a0stimuli both for targets and distractors were spoken sentences with animal names as focus word in\u00a0different position in the sentences. The experiment was conducted in a VR environment, and 20\u00a0adults participated in the experiment. The results showed that the position of the focus word in the target stimulus had a significant effect on the reaction time, while the impact of the distractor on the reaction times or error rates was not significant; however there was a trend to longer reaction\u00a0times and lower error rates when the focus word in the distractor appeared later than in the target\u00a0stimulus. This study proved that it is feasible to conduct an ASA experiment in a virtual reality\u00a0classroom with complex stimuli.<\/p>\n
