Abstract Laboratory studies, mostly with students as samples, consistently demonstrate the psychological benefits of indoor plants. However, these findings do not always translate into benefits for employees in real work contexts. In three studies, this paper first looked to replicate the findings of previous laboratory studies for the South African context and then to assess whether these findings were robust in two call centre field studies. In the laboratory study, the condition with indoor plants performed statistically better on three measures of work performance. These positive outcomes could not be replicated in two field studies using various proxy measures of performance and wellbeing (perceived productivity, perceived physical and psychological health, work engagement, job satisfaction, and evaluations of the work environment) with varying lengths of exposure to indoor plants (6 weeks in Study 2 and 14 weeks in Study 3). The moderating role of connectedness to nature (Studies 1 and 2) was not supported while the moderating role of attractiveness of the plants (Study 3) was only partially supported in Study 3. These results are discussed in relation to the differences between laboratory and field studies, specifically in the context of call centre agents.

室内植物是否可以提高办公室的绩效和幸福感？实验室和实地研究的不同结果

摘要 实验室研究，主要以学生为样本，一致地证明了室内植物的心理益处。然而，这些发现并不总能转化为实际工作环境中的员工福利。在三项研究中，本文首先着眼于复制先前针对南非背景的实验室研究的结果，然后评估这些发现在两项呼叫中心实地研究中是否可靠。在实验室研究中，室内植物条件在三个工作绩效指标上的表现在统计学上更好。这些积极的结果无法在两项使用绩效和幸福感（感知生产力、感知身心健康、工作投入、工作满意度、和工作环境的评估）与室内植物接触时间不同（研究 2 中为 6 周，研究 3 中为 14 周）。研究 3 不支持与自然的联系（研究 1 和 2）的调节作用，而研究 3 仅部分支持植物吸引力的调节作用（研究 3）。这些结果与实验室和田间的差异有关研究，特别是在呼叫中心代理的背景下。
