Many studies have reported an age-related decline in the ability to spell words correctly. The aim of this study was toinvestigate the deterioration on retrieving orthographic knowledge in 64 normal elderly Korean persons. The subjects were 64in total: they were composed of 22 persons in their 50s, 20 persons in their 60s, and 22 persons in their 70s or older. Weinstructed them to write from a dictation of 60 words stimuli (20 regular words, 20 irregular words, 20 nonwords). Olderadults made more errors than younger adults, and the age-related decline in performance was greater for irregular than regularand nonwords. With respect to the error pattern in the irregular words, the subjects showed more phonological plausibleerrors than phonological implausible errors. The number of self-correction was high in nonwords. Based on the results, wefound that aging differentially affects the retrieval of orthographic knowledge on regular, irregular and nonwords.
