| Abstract |
Which deficits in cognitive performance indicate the onset of a pathological deterioration process in older persons? Based on an established dementia screening test in elderly adults, a differentiation can be made between healthy cognitive performance and the onset of pathological deficits in performance (in the sense of mild cognitive impairment). The aim of the study was to investigate whether cognitive decline assessed with a dementia screening instrument is reflected in an intelligence test for adults. The dementia screening measured disorders in memory and attention, the intelligence testing battery measured information processing, working memory, perceptual reasoning, logical thinking and verbal comprehension. A total of 253 cognitively healthy, self-dependent and non-dementia persons (129 women and 124 men), aged between 60 and 91 years (M = 71.98 years; SD = ±7.13) were tested with the complete Wechsler adult intelligence scale (WAIS-IV) and the short performance test (SKT), based on the new normalization from 2015. The SKT enables an assessment of the degree of cognitive deterioration based on coloring codes of traffic lights. Green indicates normal aging, yellow mild cognitive impairment and red stands for abnormal cognitive aging. There were significant correlations between the total SKT score as a measure of total cognitive impairment and the indices of the WAIS-IV, such as information processing, working memory and perceptual reasoning. No significant covariation was found for verbal comprehension. The results suggest that in old age cognitive deterioration starts with reduced speed of information processing and impairment in the working memory log before deficits in memory are present. This finding was reflected in significant mean differences between the subjects in the category green versus yellow in the indices information processing and working memory. Under these aspects there were medium effect strengths (d = 0.60) and the second largest (insignificant) differences were shown in working memory (d = 0.39). |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 18 June 2017.
All research outputs
#15,465,171
of 22,981,247 outputs
Outputs from Zeitschrift für Gerontologie und Geriatrie
#202
of 364 outputs
Outputs of similar age
#199,084
of 317,132 outputs
Outputs of similar age from Zeitschrift für Gerontologie und Geriatrie
#6
of 11 outputs
Altmetric has tracked 22,981,247 research outputs across all sources so far. This one is in the 22nd percentile – i.e., 22% of other outputs scored the same or lower than it.
So far Altmetric has tracked 364 research outputs from this source. They receive a mean Attention Score of 4.6. This one is in the 32nd percentile – i.e., 32% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 317,132 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 28th percentile – i.e., 28% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 11 others from the same source and published within six weeks on either side of this one. This one is in the 36th percentile – i.e., 36% of its contemporaries scored the same or lower than it.
