Recognition memory and featural similarity between concepts: The pupil's point of view.

摘要: Differences in pupil dilation are observed for studied compared to new items recognition memory. According cognitive load theory, this effect reflects the greater demands of retrieving contextual information from study phase. Pupil can also occur when conceptually related old ones erroneously recognized as old, but aspects similarity that modulate false memory and responses remain unclear. We investigated issue by manipulating degree featural between (unstudied) (studied) concepts an old/new task. found with high were mistakenly identified had than those low similarity, suggesting strength evidence on which judgments based and, importantly, locus coeruleus prefrontal activity determined higher retrieval monitoring involved recognizing these items.
