Participants viewed slides depicting ordinary routines (e.g., going grocery shopping) and later received a recognition test. In Experiment 1, there was higher recognition confidence to high-schema-relevant than to low-schema-relevant items. In Experiment 2, participants viewed slide sequences that sometimes contained a cause (e.g., woman taking orange from bottom of pile) but not an effect scene (oranges on floor), or an effect but not a cause scene. Participants mistook new cause scenes as old when they viewed the effect; false alarms to cause scenes and high-schema-relevant items increased with retention interval. Experiment 3 showed that the backward inference effect was accompanied by false explicit recollection, whereas false alarms to schema-high foils were based on familiarity. This suggests that the 2 types of inferential errors are produced by different underlying mechanisms.
Subjects studied faces in a full-or a divided-attention condition and then received a recognition test that included old faces, new faces constructed by combining facial features from previously studied faces ("conjunction faces"), and partly or completely new faces. Full-but not dividedattention subjects responded "old" more often to old than to conjunction faces; all subjects responded "old" to these faces more often than to partially or completely new faces. Thus it is less attentionally demanding to encode facial features than it is to encode their interrelations. Dividing attention had identical effects on an incidental and an intentional learning group. Experiment 3 demonstrated that dividing attention primarily affected explicit recollection rather than stimulus familiarity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
