摘　　要：任务中断是人机互动中常见的一种现象。关于中断延迟期间心理作用机制的主要理论包括:任务转换理论、长时工作记忆理论、目标记忆理论和线程认知理论。任务转换理论为中断延迟作用机制的研究提供了基础的模式,长时工作记忆理论和目标记忆理论各自提出了复述和编码两种不同的观点,线程认知理论主张多线程并行,深化了任务中断的研究。未来研究应关注中断对主任务执行产生不同影响的原因、影响中断任务执行期间复述机会的因素等。In this paper we discuss some issues about task interruption. We try to summarize the existing experimental results and theoretical results and analyze what these studies show. Then, we hope that our study can inform researchers about what has been done about this area. More importantly, we’d like to further explore the direction and focus of future research. In the first place, based on the literature review of previous task interruption studies, we present task interruptions’ background and theories. The rapid development of Internet technology weakens the space-time boundary of traditional environment. Virtual settings emerge in that the interaction and the sense of immersion in network using expand settings from geographical areas to cyberspace. Human behavior setting is divided into real settings and virtual settings. Interaction between these behavior settings generates a new environment system-＂R-V＂ mesosystems （＂real-virtual＂ mesosystems）.The intermingling of real and virtual behavior programs within ＂R-V＂ mesosystems reflects the polyfunctional nature of settings. In these settings, human-computer interaction（HCI） is common. In addition to efficient processing of information, HCI also brings information overland, psychological stress, health damage and interpersonal stress. These negative impacts result from the fact that humans have to face and deal with frequent task interruption and switching. Thus, it’s important to study task interruption and a series of related issues in ＂R-V＂ mesosystems. In this paper, we summarize how task interruptions will affect primary task execution. We think that task interruption is a double-edged sword. Especially we comment on the theories on the psychological mechanism of interruption lag. So far this area has been working well. The related theories include task-switching, long-term working memory, memory-for-goals and threaded cognition. The task-switching theory advocates that one may prepare retrieval in interruption lag by a sort of me
