Objective: To determine whether people with dementia (PwD), and carers of PwD, show a processing bias
to dementia-related words in an emotional Stroop task, and if so, whether the presence of such a bias is
related to level of explicit awareness of the condition.
Method: Seventy-nine people with early stage Alzheimer’s disease (AD), vascular or mixed dementia, and
their carers, completed an emotional Stroop task. Time taken to colour-name dementia-related and
neutral words was compared within and between groups. Additionally, as a comparison, ratings of the
awareness of the condition shown by PwD were made on the basis of a detailed interview with each PwD
and his/her carer.
Results: PwD and carers showed the same level of increase in response times to salient compared to
neutral words. In the PwD this effect was unrelated to the degree of awareness that they demonstrated
regarding the condition.
Conclusions: The emotional Stroop effect in response to dementia-related words in PwD indicates that
preserved implicit awareness of the condition can be elicited even where there is reduced explicit
