This research examined the extent to which variations in adults' subjective age identities were related to information provided by proximal age markers, which are specific age-symbolic experiences presumed to channel shifts in age identities. To this end, adults' psychological, physical, and social subjective age identities were examined in relation to the nearness of their birthdays. In the absence of proximal age information, younger and older adults showed distinctive age-related changes in subjective age. On the other hand, older men's and women's social subjective ages as well as older women's psychological subjective age were less youthful the nearer their birthdays. However, younger adults' age identities did not vary with the closeness of their birthdays. Several gender differences in addition to the moderating effects of adults' awareness of their age and their attitudes toward aging were also observed.KEY WORDS: Subjective age; life events; age awareness; attitudes toward age; gender differences.
INTRODUCTIONA fundamental issue in the study of adult development and aging is specifying the nature of the age variable. Despite the fact that chronological age has served as the preferred dimension along which behaviors are studied, Birren and Cunningham (1985) have argued-that progress in the field would be greatly advanced through attempts to augment or replace it with constructs tied more closely to intrinsic aging processes. Subjective age, or how young or old adults experience themselves to be, is one such construct.Empirical research on subjective age emerged in the 1950s by researchers interested in understanding adults' attitudes toward aging (see Barak & Stern, 1986;Peters, 1971, for reviews of relevant research).

More specifically, the accumulated data using multiple age groups has shown that, whereas adults in their 20s often perceive themselves as slightly psychologically, physicaUy, and socially older than their actual age, adults over 30 years of age generally perceive themselves as younger than their actual age. Moreover, differences between actual and subjective age become more pronounced with advancing chronological age.Consistent with indications that intrinsically oriented constructs may be better indicators of psychological and physical functioning than chronological age (George, Mutran, & Pennybacker, 1980;Linn & Hunter, 1979; Neugarten & Hagestad, 1976;Nuttall, 1972), Montepare (1996aMontepare ( , 1996b has found that adults' subjective age is typically a st...
