In this study, we introduced familiarity-related inducer items (expressions referring to the participant’s self-related, familiar details: “mine,” “familiar”; and expressions referring to other, unfamiliar details, e.g., “other,” “irrelevant”) to the Complex Trial Protocol version of the P300-based Concealed Information Test (CIT), at the same time using different item categories with various levels of personal importance to the participants (forenames, birthdays, favorite animals). The inclusion of inducers did not significantly improve the overall efficiency of the method as we would have expected considering that these inducers should increase awareness of the denial of the recognition of the probes (the true details of the participants), and hence the subjective saliency of the items (Lukács in J Appl Res Mem Cognit, 6:283–284, 2017a). This may be explained by the visual similarity of inducers to the probe and irrelevant items and the consequent distracting influence of inducers on probe-task performance. On the other hand, the CIT effect (probe-irrelevant P300 differences) was always lower for less personally important (low-salient) and higher for more personally important (high-salient) items.

在基于P300的经过修改的CTP隐藏信息测试中探讨的项目角色。

在这项研究中，我们介绍了与熟悉程度相关的诱发因素项（表达是指与参与者自身相关的，熟悉的细节：“我的”，“熟悉的”；表达是指其他不熟悉的细节，例如“其他”，“无关的” ），以基于P300的隐蔽信息测试（CIT）的复杂试验协议版本为基础，同时使用对参与者具有不同程度个人重要性的不同项目类别（姓氏，生日，喜欢的动物）。考虑到这些诱导剂应该增加人们对拒绝识别探针的认识（参与者的真实详细信息），因此我们的主观显着性，考虑到诱导剂的加入并不能显着提高该方法的整体效率。项目（JAppl Res Mem Cognit中的Lukács，6：283–284，2017a）。这可以通过诱导剂与探针和无关项目的视觉相似性以及诱导剂对探针任务性能的分散注意力影响来解释。另一方面，对于个人重要性较低的项目（低显着性），CIT效果（与探针无关的P300差异）始终较低，而对于个人重要性较高的项目（高显着性）则始终较高。
