While the social-structural construction of cultural taste has been a sustained subject of inquiry within the sociology of culture, its temporal dynamics have not received the same treatment. Using repeated cross-sectional survey data (1982-2012) and a novel age-period-cohort estimation strategy that treats cohort effects as age-by-period interaction effects, we detail how (a) age-graded trajectories, (b) historic fluctuations, and (c) generational acculturation jointly determine the temporal dynamics of cultural omnivorousness among Americans. First, we find that omnivorousness accumulates over the life-course in age-graded trajectories. Individuals experience their peak levels of omnivorousness in the mid-to-late stages of adulthood. Taste acquisition is most rapid in the early phases of adulthood, and slows down towards the late phases of adulthood. Second, omnivorousness is subject to unpredictable historic fluctuations. Sharp increases in the 1990s recess and stabilize in the two decades to follow. Third, generational acculturation affects omnivorousness in uneven ways. Baby boomers experience higher than expected levels of omnivorousness, while the cohorts preceding and succeeding the Baby Boomers instead experience lower than expected levels of omnivorousness. Generational acculturation may also manifest most strongly in the early and late stages of adulthood. Our results imply that any temporal analysis of culture cannot avoid dealing with the age, period and cohort identification problem, that the period affect associated with the 1992 wave of the SPPA persists even in an age-period-cohort analysis, and that generational differences are endogenous to any time-invariant index of cultural taste.

尽管文化品味的社会结构建构一直是文化社会学研究的一个持续课题，但其时间动态却未得到同样的对待。使用重复的横断面调查数据（1982年至2012年）和一种将年龄段影响视为年龄段交互作用的新颖的年龄段年龄段估算策略，我们详细介绍了（a）年龄等级轨迹，（b）历史路线波动和（c）代际适应共同决定了美国人中文化杂食性的时间动态。首先，我们发现杂食性会随着年龄的变化在整个生命过程中积累。在成年中后期，个体会经历杂食性的最高水平。在成年初期，味觉习得最快，并减缓至成年后期。其次，杂食性会受到不可预测的历史性波动的影响。1990年代休假期间急剧增加，并在随后的二十年中趋于稳定。第三，世代相依以不均匀的方式影响杂食性。婴儿潮一代的杂食水平高于预期，而婴儿潮一代之前和之后的同类人群的杂食水平则低于预期。在成年的早期和后期，代际适应也可能最明显。我们的结果表明，对文化的任何时态分析都无法避免应对年龄，时期和队列识别问题，即使在年龄-年龄-队列分析中，与1992年SPPA浪潮相关的周期影响仍然存在，
