Accurate Judgment by Dementia Patients of Neutral Faces with Respect to Trustworthiness and Valence
Abstract
The present study investigates whether dementia patients can make accurate social and affective judgments of face stimuli. We used verbal material as a control condition to see whether dementia patients are capable of using the rating scales the same way as controls. We compared the trustworthiness, valence, and arousal ratings of dementia patients with those from a healthy control group. Participants rated pictures of young and old, female and male neutral faces and two fictitious biographies. The results indicate that dementia patients make accurate judgments of unfamiliar faces with respect to trustworthiness and valence. Results concerning arousal ratings suggest that the corresponding scale might be difficult to use for dementia patients and possibly for older participants as well.
