The feature boost refers to increased false memories for word lists that are both associatively and categorically (C + A) related to a non-presented critical item (CI) relative to lists that are only associatively (NC-A) related [Coane, J. H., McBride, D. M., Termonen, M.-L., & Cutting, J. C. (2016). Categorical and associative relations increase false memory relative to purely associative relations. , (1), 37-49. doi:10.3758/s13421-015-0543-1]. We explored the replicability of the feature boost and its dependance on monitoring processes by explicitly warning participants about the nature of the lists or by asking participants to guess the CI (implicit warning). Overall, the feature boost was replicated. Guessing performance was higher for C + A lists than for NC-A lists. Explicit warnings were equally effective for both list types in reducing false memory relative to recall and to a no-recall math condition. When the CI was not guessed or recalled, the feature boost emerged. However, when the CI was guessed or previously recalled, false alarms did not differ as a function of list type. The feature boost seems to be driven in part by differences in the identifiability of the CI, such that CIs related to C + A lists are harder to identify and thus reject. These results suggest that differences in monitoring processes that are sensitive to CI identifiability contribute to the effect.
特征促进是指与未呈现的关键项目（CI）相关的列表（无论是在联想上还是在类别上都与 CI 相关，即 C+A）相比，与仅在联想上相关的列表（NC-A）相比，对单词列表产生更多虚假记忆[Coane, J. H., McBride, D. M., Termonen, M.-L., & Cutting, J. C. (2016). Categorical and associative relations increase false memory relative to purely associative relations., (1), 37-49. doi:10.3758/s13421-015-0543-1]。我们通过明确警告参与者列表的性质或要求参与者猜测 CI（隐含警告），探索了特征促进的可重复性及其对监测过程的依赖关系。总体而言，特征促进得到了复制。对于 C+A 列表，猜测性能高于 NC-A 列表。与回忆和无回忆数学条件相比，显式警告对于两种类型的列表都同样有效地减少了虚假记忆。当 CI 未被猜测或回忆时，出现了特征促进。然而，当 CI 被猜测或先前被回忆时，虚假警报不会因列表类型而异。特征促进似乎部分是由 CI 可识别性的差异驱动的，即与 C+A 列表相关的 CI 更难识别，因此更难拒绝。这些结果表明，对 CI 可识别性敏感的监测过程的差异有助于产生这种影响。
