Abstract
Abstract
Aging involves a variety of cognitive and language changes. Word association norms (WANs), which describe the
first word people say or write after reading or hearing a stimulus word, reflect the organization of semantic knowledge. The aim
of this study was to create a WAN corpus for Mexican older adults, with 114 participants responding to 117 nouns. The results of
eight measures of word-word relationships showed that participants generated an average of 38.14 different response words for each
stimulus word. Of these responses, 41.88% were of high associative strength and 20.70% were idiosyncratic, demonstrating the
uniqueness of responses of older adults. In addition, we compared their responses to a corpus for younger adults (Barrón-Martínez & Arias-Trejo, 2014). A qualitative analysis categorizing the
responses into syntagmatic and paradigmatic types showed that the older group tended to respond with words from a different
grammatical class. Responses of the younger adults were also more cohesive and less varied than those of the older group. This
corpus for older adults is an essential resource for evaluating age-related changes in semantic memory, and it provides a point of
comparison for responses from people with neurodegenerative diseases.
