“…In the choosing task, (10, 5 Migr) was preferred to (20, 5 Migr), but in the matching task, the participant assigned a higher value to (20, 5 Migr) than to (10, 5 Migr). Traditional preference reversals (Beattie & Baron, 1991;Bimbaum et al, 1992;Bostic, Herrnstein, & Luce, 1990;Casey, 1991;Cho, Luce, & yon Winterfeldt, 1994;Delquit, 1993;Fischer & Hawkins, 1993;Fischhoff et al, 1980;Goldstein & Einhorn, 1987;Gonz,~iles-Vallejo & Wallsten, 1992;Grether & Plott, 1979;Hawkins, 1994;Hershey & Schoemaker, 1985;Johnson & Schkade, 1989;Lichtenstein & Slovic, 1971;Lichtenstein & Slovic, 1973;Lindman, 1971;Loomes et al, 1989;Mellers, Chang, et al, 1992;Mellers, Ord6fiez, & Birnbaum, 1992;Pommerehne et al, 1982;Slovic, 1975;Slovic et al, 1990;Slovic & Lichtenstein, 1983;Tversky et al, 1988;Tversky et al, 1990) occur when stimuli are compared for more than one attribute, and they have been explained mostly by changes in the weighting with which the attributes are combined in different tasks.
