Which you want to do because comparing the reaction time data of contemporaries of different ages allows you to take snapshots of reaction time data from different generations. When you do that, you found that older generations had better reaction times, which has some correspondence with better general intelligence.Adam G.http://www.jrganymede.comnoreply@blogger.com
