Metacognitive judgment and denial of deficit: Evidence from frontotemporal dementia
Journal Title: Judgment and Decision Making - Year 2007, Vol 2, Issue 6
Abstract
Patients suffering from the behavioral variant of Frontotemporal Dementia (FTD-b) often exaggerate their abilities. Are those errors in judgment limited to domains in which patients under-perform, or do FTD-b patients overestimate their abilities in other domains? Is overconfidence in FTD-b patients domain-specific or domain-general? To address this question, we asked patients at early stages of FTD-b to judge their performance in two domains (attention, perception) in which they exhibit relatively spared abilities. In both domains, FTD-b patients overestimated their performance relative to patients with Dementia of Alzheimer Type (DAT) and healthy elderly subjects. Results are consistent with a domain-general deficit in metacognitive judgment. We discuss these findings in relation to “regression to the mean” accounts of overconfidence and the role of emotions in metacognitive judgments.

According to Karl Popper, we can tell good theories from poor ones by assessing their empirical content (empirischer Gehalt), which basically reflects how much information they convey concerning the world. “The empirical...
