Electroencephalographic μ wave suppression was investigated using all 10 static, ambiguous Rorschach stimuli. In an earlier study using four Rorschach stimuli, the two stimuli that elicited feelings of movement were associated with μ suppression. In this study, we replicated this relationship using all 10 Rorschach stimuli while overcoming a number of other earlier limitations. The results strongly support the hypothesis that internal representation of the feeling of movement is sufficient to suppress the μ rhythm even when minimal external cues are present. This outcome increases the generalizability and ecological validity of this approach and gives support to the traditional interpretation of the Rorschach human movement responses as being associated with cognitive functioning, empathy, and social cognition.
使用全部10种静态、含混的罗夏墨迹测验刺激来研究脑电图μ波抑制。在一项早期使用四种罗夏墨迹测验刺激的研究中，两种引发运动感觉的刺激与μ波抑制相关。在本研究中，我们使用全部10种罗夏墨迹测验刺激重复了这种关系，同时克服了一些其他早期的局限性。结果有力地支持了这一假设，即即使存在极少的外部线索，运动感觉的内部表征也足以抑制μ节律。这一结果提高了该方法的普遍性和生态效度，并支持了对罗夏墨迹测验中人类运动反应与认知功能、同理心和社会认知相关的传统解释。
