A classic example of an item-order effect was demonstrated by Strack, Martin, and Schwarz ($1988$) in a study asking college students about their general life satisfaction and dating frequency. When the life satisfaction question was asked first, the two variables showed a weak negative correlation ($-.12$). However, when the dating frequency question was presented first, the correlation became strongly positive ($+.66$). Asking about dating first made that specific information highly accessible in memory, causing participants to base their overall life satisfaction ratings heavily on their dating frequency.
