Low shame scores on self-reported measures do not distinguish between genuine and defensive low (unacknowledged) shame associated with narcissistic grandiosity. To distinguish between them, we intensified shame-inducing scenarios of the self-report measure of shame- and guilt-proneness and applied them with the original scenarios and with self-report measures of grandiose and vulnerable narcissistic personality traits to 1,077 Croatian students from diverse universities (Mage = 24.63; 85.51% female) recruited online. We defined shame responsiveness as the average difference between shame scores on the intensified and original scenarios and assumed that participants with genuine low shame would report greater shame on intensified scenarios, whereas those with defensive low shame may rigidly mobilize unconscious defenses and tend not to report greater shame (shame unresponsiveness). Data analyses supported this. In contrast to narcissistic vulnerability, as grandiosity (and, presumably, unacknowledged shame) increased, self-reported shame-proneness and shame responsiveness decreased. Participants who were unresponsive to intensified scenarios were significantly more likely to be high in grandiosity than those whose average shame score increased. Unresponsiveness to scenarios of increased intensity suggests a defense against shame experiences, rather than low propensity to shame experiences and may help us identify participants whose low self-reported shame (only) hides a large portion of shame that cannot be acknowledged and that otherwise remains unexamined. 在自我报告测试中，低羞耻感得分不能区分出真实的和防御性的（未被承认的）与自恋夸大相关的羞耻感。为了区分二者，我们在自我报告的羞耻感和负罪感倾向测量中，强化了羞耻诱导情境，并将其应用到原始情境以及夸大和脆弱的自恋人格特征的自我报告的测量中，这是对线上招募的1077名来自不同大学的克罗地亚学生（Mage=24,63;85,51%女性）的测量报告。我们将羞耻感反应定义为在强化情境和原始情境中的羞耻得分之间的平均差异，并假设有真实的低羞耻感的参与者会在强化情境中报告更强的羞耻感，而那些防御性低羞耻感的人可能会刻板地发动无意识防御，并倾向于不报告更强的羞耻感（无羞耻感反应）。数据分析支持了这一点。与自恋的脆弱形成对比的是，夸大感（未被承认的羞耻感，据推测）增加，自我报告的羞耻感倾向和羞耻感反应能力下降。对于强化情境无反应的参与者明显更有可能比那些平均羞耻分升高的参与者有更大的夸大性。对强化情境没有反应提示了对羞耻体验的防御，而不是较低的羞耻体验倾向，这可以帮助我们识别那部分参与者，他们自我报告的低羞耻感（只是）隐藏了一大部分未被承认或未经检验的羞耻感。
