This article is based on a part of the first author's master's thesis from Dankook University. Objectives: The purpose of this study is to investigate whether elderly groups are able to do semantic processing during a picture-word interference task and whether their semantic processing is more affected by words in the same category or different categories. Methods: The participants in this study were 15 younger adults and 15 normal elderly. The tasks were composed of conditions where the target stimulation and distractive stimulation were in the same category or in different categories. The tasks were composed of a total of 30 questions. On the picture-word interference task, participants were supposed to name the picture. Results: The results of the study are summarized as follows. First, on the picture-word interference task, the accuracy of response of the elderly group was significantly lower than the younger group. Second, the reaction time of the elderly group was significantly slower, but both groups had a longer reaction time in the same category condition. Conclusion: The results indicated that the elderly group had more interference effects than the younger group. Although both groups resolved interference, the reaction time of the elderly group was slower. But in the same category condition, both groups had a longer reaction time than in different category conditions.

This research was extracted from the part of Master's thesis (2007) of the first author. Objectives: The present study aimed to elucidate the nature of semantic impairment in action verbs focusing on instrumentality, as revealed in a verb naming and a comprehension tasks completed by healthy elderly and patients with Alzheimer's disease (AD). Methods: Twelve patients with mild and moderate AD and 12 healthy elderly participated in the study. Forty action verbs from 20 instrument verbs and 20 non-instrument verbs were selected for both confrontation naming and word-picture matching tasks. Task effect as well as semantic effect of instrument verbs was analyzed by using two-way mixed ANOVA and post-hoc analyses. Results: Verb naming and comprehension abilities in patients with AD were significantly poorer than healthy elderly. Unlike the healthy elderly, AD patients showed significantly lower naming scores for instrument verbs than for non-instrument verbs. Meanwhile, no instrumentality effect was found in the word-picture matching task for either group. Conclusion: These results confirm previous studies that report verb naming and comprehension deficits in patients with AD, and extend the finding to the semantic category of instrument verbs. Naming deficits in instrument verbs seem to be related to the loss of the semantic feature relationship between verbs and their corresponding nouns. The feature-based framework in semantic memory is discussed further.
20s to 80s, considering phonological and lexical routes of reading. Methods: This study classified 120 normal adults into a younger group (20-39 years), middle-age group (40-59 years), and older group (60-89 years), and conducted a reading aloud task under various conditions. Results: The performance of the older group decreased in irregular words and regular nonwords compared to the younger (p < .001) and middle age (p = .001) groups. For irregular nonwords, performance of the older group decreased compared to the younger group (p = .002). Conclusion: The results show that lexical routes for reading irregular words with graphemes and phonemes not corresponding to each other are affected by aging. This signifies that the cognitive load for reading irregular nonwords grows with age; these nonwords should be read by borrowing phonological changes in words with similar phonological conditions through phonological and lexical routes. To sum up, declines in language ability and cognitive functioning and reduced attention during the normal aging process can affect the ability to use information through lexical routes, and reading that requires complex cognitive processing is more affected by aging.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
