Assessing the nomological validity of a cognitive age segmentation of Japanese seniors

Abstract

PurposeThe purpose of this paper is to use cognitive age to segment college‐educated Japanese seniors, a grouping of interest to many marketers both within and external to Japan. The intent is to demonstrate the nomological validity of the cognitive age concept by relating it to key externalities and to further assess the viability of cognitive age over chronological age in non‐Western segmentation research.Design/methodology/approachBoth hierarchical and non‐hierarchical clustering are employed to form segments of Japanese seniors based on their average cognitive age, as revealed by both Likert and semantic‐differential scaling. Differences are sought between the two clusters on key segmentation variables.FindingsThe results reveal that Japanese seniors who are younger, psychologically speaking, have more positive attitudes toward life satisfaction and aging than those respondents who are cognitively older. The psychologically younger respondents also tend to be more involved in activities and have better health along with economic comfort. The study further demonstrates, in a non‐Western setting, the predictive power of cognitive age over chronological age since the revealed cognitive age segments have the same chronological age.Practical implicationsThe fact that average cognitive age relates to one's health makes it a powerful segmentation variable in international segmentation research on the mature market. Basically, cognitive age reveals an aptitude and, when coupled with purchasing power, the viability of senior segments may be assessed more clearly and strategically.Originality/valueThe study validates the usefulness of cognitive age in global segmentation research and illustrates its potential as a better predictor of behavior than chronological age.
