Journal article (peer-reviewed)abstract
- This study examined the effect of color and form as support for picture recognition measured immediately and after a period of 20 minutes in two groups: a random sample of 80-year-old men and women, with a Mini-Mental-State-Examination (MMSE) score of >26 points (N=142), and individuals with confirmed diagnosis of Alzheimer's disease (AD) with a MMSE score ranging from 7-26 points (N=50). The result showed that individuals with AD could make use of spatial support for recognition at a significantly lower level than among the cognitively intact 80-year olds, but most interestingly with a similar pattern. Chromatic pictures had an advantage over achromatic ones on immediate recognition measured as less time consumption and a higher number of correct answers in both groups. However, after 20 minutes' retention time, achromatic pictures were better recognized than chromatic ones by both the 80-year olds and the individuals with AD. It is suggested that immediate recognition had most support from self-generated cues concerning color, in contrast to retained recognition where instead cues concerning form had the strongest impact. Gender and age had no influence on recognition. Visual function and abstract vs concrete objects showed a slight impact on the result. Factors of intelligence and memory in the group of 80-year olds only had a minor influence on recognition, contrary to dementia which had a profound impact. It is concluded that spatial support as to color and form could be used for recognition in old age groups. The result will encourage further experimental research in using coding and cueing strategies for future implications in clinical practice.

Colour perception among the very elderly related to visual and cognitive function.

Journal article (peer-reviewed)abstract
- Colour perception was studied among a representative sample of 95-year olds and compared with previously examined 80-year olds and a group with Alzheimer's disease (AD), mean age of 80 years. The 95-year olds' results were on a significantly lower level than the other two groups but showed a similar pattern as to colour -discrimination, -naming, -preferences and colour/form recognition. Visual function among 95-year olds had only minor influence on their result in contrast to cognitive function which had a more profound impact. Most interestingly though, the subjects with Alzheimer's diagnosis, younger than the 95-year olds but with a conclusive diagnosis of dementia, performed on an overall higher level than the 95-year olds. This advantage for the Alzheimer group remained even when compared with a sub sample of the 95-year olds with possible dementia diagnosis excluded. On the other hand, only including 95-year olds with a Mini Mental Examination score of >26 in comparison with the Alzheimer group made the differences between the two groups disappear. It is suggested that colour perception as measured in this study is well preserved throughout life. The overall lower colour perception ability in 95-year olds compared with both 80-year olds and subjects with AD may be an expression of the complexity of very high age rather than any isolated concomitant factor.
