Using a cross-sectional design, we would test different age groups in the year 2014 and compare their performance. Using a longitudinal design, we would test one age group and then retest them every 10 years until age 60. Using a sequential design (there are many types), we might test 10- through 60-year-olds in the year 2014 and then retest them every 10 years until age 60. Sequential design: repeatedly testing several age cohorts as they grow older, most comprehensive, but also most time-consuming and costly, they visual acuity is about 20/800 or 40 times worse than normal adult acuity of 20/20. Within 72 hours of birth, infants distinguish the familiar face to their.
