The Importance of Truth: Joint Retrieval of “True” and “Important” Feedback in Multidimensional Source Memory

Source memory for truth is usually better than for falsity and similar effects are observed for important compared with unimportant information. A recently found interaction between information veracity and importance indicates that people effectively prioritize encoding true information (but not false). Yet, it is unclear whether the feedback about veracity and importance of the information is integrated into joint memory representation. In the following experiment, we investigated if source memory for veracity and importance dimensions is stochastically dependent. Students (N = 82) memorized trivia statements along with their veracity and importance status which resulted in four different combinations of sources (“true and important”, “true and unimportant”, “false and important”, “false and unimportant”). The analysis with a multidimensional source memory multinomial model revealed that the joint retrieval of “true” and “important” feedback as compound information is better than for all other combinations. Moreover, the veracity dimension was memorized better than the importance dimension, showing that we remember whether information is true or false better than whether it is important or unimportant. notReviewed other
