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.
本研究的目的是根据不同任务对无关言语干扰的敏感程度，测试哪些任务适合在开放式办公室中开展。所选任务旨在挖掘办公室工作的基本能力，包括：搜索相关信息、记忆材料、计数以及生成单词。研究假设是，需要语义处理的任务会受到无关言语的干扰。为确定绩效下降的幅度，对两种声音条件（安静、无关言语）进行了比较。结果表明，基于情景短期记忆和对所呈现材料进行复述的任务，比那些不需要复述或基于长期记忆检索的任务，对无关言语的干扰更为敏感。本研究表明，诸如信息搜索和材料记忆等任务，并不适合在无关言语普遍存在的工作环境中开展。
