本研究的目的是测试哪些任务适合在开放式办公室中工作，根据这些任务容易受到不相关言论的干扰的程度。选择这些任务是为了挖掘办公室工作的基本能力，包括：搜索相关信息、记住材料、计数和生成单词。假设是需要语义处理的任务应该受到不相关语音的损害。为了确定性能下降的程度，对两种声音条件（安静、不相关的语音）进行了比较。结果表明，基于情景短期记忆和所呈现材料的排练的任务比不需要排练或基于长期记忆检索的任务对不相关语音的干扰更敏感。本研究指出，在不相关言论无处不在的工作环境中，信息搜索和材料记忆等任务是不合适的。
The aim of the present study was to test which tasks are suitable for work in open-plan offices according to how susceptible they are to disruption produced by the mere presence of irrelevant speech. The tasks were chosen to tap fundamental capacities of office work involving: search for relevant information, remembering material, counting, and generation of words. The hypothesis was that tasks requiring semantic processing should be impaired by irrelevant speech. To determine the magnitude of performance decrease, two sound conditions (quiet, irrelevant speech) were compared. The results showed that tasks based on episodic short-term-memory and rehearsal of the presented material were more sensitive to disruption by irrelevant speech than tasks which did not require rehearsal or were based on long-term memory retrieval. The present study points to the inappropriateness of tasks, such as information search and remembering of material, for work environments within which irrelevant speech is ubiquitous.
