Positive Bias in Confabulation Effects of Agent and Aging

View Full Record
Description: Previous research has shown that confabulators, as well as healthy older adults, are more likely to endorse positive false information than negative false information as true compared with younger individuals. This pattern is known as the positive bias. However, most prior studies have evaluated the positive bias in confabulation with autobiographical information (i.e., memories in relation to the self). Thus, it is unclear whether this positive bias extends to other types of memories. This study investigated whether a positive bias encompasses recognition of self-referent but non-autobiographical information (e.g., written in first person). A secondary goal of this study was to examine the effects of normal aging on the positive bias. Additionally, this study examined the point in the memory retrieval process where confabulators are deficient. The results provide support for a cognitive monitoring deficit in confabulation, but the study failed to produce a significant positive bias in the confabulator group.
