The effect of experimenter expectancy was investigated on the resistance to respiratory air flow, measured as total respiratory resistance (Rt) in healthy individuals.
Each of three naive experimental assistants collected air flow resistance responses from 30 subjects who they had been told were either likely or unlikely to respond to the suggestion of breathing difficulty.
The subjects were assigned to the two conditions at random. The subjects who were described to the experimenters as being likely to respond exhibited greater Rt increases to bronchoconstriction suggestion than did the subjects who were described as unlikely to respond.
These findings confirmed the presence of a source of variance that has not been considered previously in suggestion studies.
研究实验者预期对健康个体呼吸气流阻力的影响，以总呼吸阻力（Rt）作为衡量指标。
三名无经验的实验助手分别从30名受试者收集气流阻力反应，这些受试者被告知对呼吸困难建议的反应可能有差异。
受试者被随机分配到两种情况。被实验者描述为可能有反应的受试者，与被描述为不太可能有反应的受试者相比，对支气管收缩建议表现出更大的Rt增加。
这些发现证实了在暗示研究中存在一个以前未被考虑的方差来源。
