Differences in Blame-Like and Forgiveness-Like Judgments between Young People, Healthy Older People, and Older People with Dementia

The objective of the present experimental study was to compare how young people, healthy older people, and older people with dementia cognitively integrated three factors (Intention, Consequence, and Apology) when making blame-like judgments (prosecution and revenge) and forgiveness-like judgments (resentment and reconciliation). Thirty-four young people (Mage = 22.12, SD = 3.44), 22 healthy older people (Mage = 71.82, SD = 8.69), and 18 older people with dementia (Mage = 75, SD = 10.06) participated in the study. The participants were confronted with 12 scenarios built by combining the three factors for each moral judgment. Analyses of variance with repeated measures were applied to the study data. Whatever the type of judgment, older people with dementia differed from young people and healthy older people about the number of factors considered. Young people and healthy older people used the three information cues (Intent, Consequence, and Apology) for the four judgment tasks (prosecution, revenge, reconciliation, and resentment). In comparison, older people with dementia gave greater weight to Intention. In contrast to young and healthy older people, older people with dementia processed blame-like and forgiveness-like judgments similarly. The cognitive impairment prevented older people with dementia from differentiating moral judgments into two categories and reduced information integration when making moral judgments. These findings might be useful for clinical practice.
