Introducing the Recency Ratio

Individuals with Alzheimer’s disease have been found to present a typical serial position
curve in immediate recall tests, showing poor primacy performance and exaggerated
recency recall. However, the recency advantage is usually lost after a delay. On this basis,
we examined whether the recency ratio (Rr), calculated by dividing recency performance
in an immediate memory task by recency performance in a delayed task, was a useful risk
marker of cognitive decline. We tested whether change in Mini-Mental State Examination
(MMSE) performance between baseline and follow-up was predicted by baseline Rr and
found this to be the case (N = 245). From these analyses, we conclude that participants
with high Rr scores, who show disproportionate recency recall in the immediate test
compared to the delayed test, present signs of being at risk for cognitive decline or
dysfunction.

The rest is here. (Wife-photo-credit :)))
