An experiment was conducted to investigate the claim that human performance may be enhanced by exposure to artificially high concentrations of negative air ions. 16 subjects, only half of whom were informed of the ion level in each session, performed reasoning, psychomotor, and memory-search tasks. Despite adequate control of confounding variables, no clear evidence was obtained in support of the view that negative ions in the air influence performance.
进行了一项实验，以调查暴露于人为高浓度的负离子环境中是否能提高人类表现这一说法。16名受试者参与了推理、心理运动和记忆搜索任务，其中只有一半人在每次实验中被告知离子水平。尽管对混杂变量进行了充分控制，但没有获得明确证据支持空气中的负离子会影响表现这一观点。
