The fact that Tatiana likes to watch reality television and her grandfather prefers watching 1960s television westerns is probably best explained by: cohort effects
Step-by-step explanation:
A cohort is a collection of people who share a distinct characteristic. A shared characteristic is a life situation that got position in a particular period, like birth or high class convocation. The common usually studied cohorts are age-related (e.g. somebody who experience a birth year or generational specification).
The influence of the characteristics of a cohort on the outcomes of a analysis study is termed as cohort effect. Psychological researches lead to concentrate on birth or generational cohorts. Such cohorts experience general life experiences and experience comparable social trends. Here Tatiana and her grandfather sharing of distinct characteristic is explained based on cohort effects.
