Previous research on preferences has indicated that young adults may construct their preferences as a result of their choices. In the present study, the author investigated the effects of aging on preference construction. 80 younger adults and 80 older adults rated how desirable and important they found various vacation attributes, made a choice between two vacation options, and then rated the attributes again. Results suggest that older and younger adults show a similar pattern of preference shift to support their choice, with partial evidence suggesting that older adults shift their preferences slightly more toward the positive.
