Abstract

[Objective] With the development of information technology, interruption phenomenon becomes more and more common to the mental workers. On the previous study of interrupts are microscopic, rather than as a whole. This experiment was used to explore the influence of the position and cognitive load of interruption on the primary task. [Methods] There are 75 college students in 9-step sequential human-computer task test experiment. Character recognition and judging work is used in the primary task. In 8 positions between 9 steps, interruption tasks appeared equal probability. There is only one interruption in each cycle. Participants were divided into three groups, one group's interruption tasks are entering the characters, the second group's interruption tasks are the simple numerical calculation, the third group's interruption tasks are complex numerical calculation. Computer program records the subjects' overall operation process. [Results] Results show that: (1) in the experiment, the error rates and response latencies caused by different interruption-positions had significant difference. (2) There were no significant differences on error rates and response latencies in different cognitive loadof interrupting tasks. [Conclusion] In sequential human-computer tasks, destructive arising out of the interruption phenomenon occurred in the middle position is significantly higher than the start and end positions.
