The aim of this study was to analyze changes in muscle activity between high and low self-critical participants during the imagery of self-compassion, self-protection, and self-criticism. Muscle activity was measured by the Biopac MP36 while participants were listening to the imagery audio recording. Levels of self-criticism were measured by The Forms of Self-Criticising/Attacking and Self-Reassuring Scale (FSCRS; Gilbert et al., 2004). From overall number of 110 participants, 30 participants were selected for further analysis based on their extreme level of self-criticism. The research sample consisted of 15 participants with high level of self-criticism and 15 with low level of self-criticism. The results showed that participants with higher levels of self-criticism had similar levels of muscle activity during the self-critical and self-protective phases of imagery. However, during the last self-compassionate imagery, participants with lower self-criticism returned to the baseline EMG levels, while those with higher self-criticism remained at high EMG levels. The results showed lower muscle activity in low self-critics while imagining inner compassionate part meaning. Therefore, low self-critics are probably better able to calm themselves down compared to high self-critics.

根据自我批评水平的自我同情和自我批评意象中肌电图的差异

本研究的目的是分析在自我同情、自我保护和自我批评的意象中，高自我批评参与者和低自我批评参与者之间肌肉活动的变化。Biopac MP36 在参与者聆听影像录音时测量肌肉活动。自我批评的水平通过自我批评/攻击形式和自我安慰量表（FSCRS; Gilbert et al., 2004）来衡量。从 110 名参与者的总数中，根据他们的极端自我批评水平选择了 30 名参与者进行进一步分析。研究样本包括 15 名自我批评水平高的参与者和 15 名自我批评水平低的参与者。结果表明，具有较高自我批评水平的参与者在图像的自我批评和自我保护阶段具有相似的肌肉活动水平。然而，在最后一次自我同​​情的意象中，自我批评较低的参与者恢复到基线 EMG 水平，而自我批评较高的参与者则保持在较高的 EMG 水平。结果表明，在想象内心富有同情心的部分意义时，低自我批评者的肌肉活动较低。因此，与高自我批评者相比，低自我批评者可能更好地让自己平静下来。结果表明，在想象内心富有同情心的部分意义时，低自我批评者的肌肉活动较低。因此，与高自我批评者相比，低自我批评者可能更好地让自己平静下来。结果表明，在想象内心富有同情心的部分意义时，低自我批评者的肌肉活动较低。因此，与高自我批评者相比，低自我批评者可能更好地让自己平静下来。
