Predicting Behavior by Knowing a Person's Age

Cohort Effect: An Explanation by Dwight Adams, 1998, Gerontology Department, University of Utah

University of Colorado: Dr Massey's "You are what you were when" is a theory of human development. He concentrates on the concept of human "value setting." It is his contention that, about age 14, American youth set their own personal "values." They do not automatically adopt someone else's values, and those personal values are influenced by more than peers, parents, schools, and social groups. They are also influenced by what was going on in the media and what the "talk of the town" was at the time. Massey claims that the "shared experiences and events" of age cohorts help set their attitudes...for life.

An example of this is tastes in music: The type of music enjoy by teenagers varies greatly due to their "place in time." Some like the Perry Como and some like "big band sound," others like jazz or rock or "heavy metal." Even dance preferences and dress & grooming standards alter according the history teenagers have lived through. Even medical differences exist, like the cohort that first took the Salk Polio vaccine, or the "tubes in the ears" (eardrum) that was so popular in the late 80s, early 90s.

Check out this cohort study. If you are over 40, find your own "age cohort group" (when you were about 14, including those as much as 5 years younger and 5 years older--10 year period of time). See if you agree with the songs that are listed as popular then. See if historical or political happenings at that time made a conscious impression on you.

If you are under 40, did you have your parents/grandparents do this exercise?
