Typically, task interruptions have a negative effect on the performance in the interrupted task. In the present study, we examined the effects of task interruptions on the performance in a typing task. Participants were instructed to type German words. Task interruptions occurred between two syllables (e.g., JUN à interruption à GE) or within a syllable (e.g., JU à interruption à NGE). In Experiment 1, the interruption task was a numerical magnitude-categorization task, whereas in Experiment 2, there was no task during the interruption. In both experiments, we found worse performance for a letter following a task interruption than for the corresponding letter in a non-interrupted word. These resumption costs were smaller for task interruptions occurring between two syllables than for task interruptions occurring within a syllable. We discuss these findings in the in the framework of task-interruption and word-typing models.
