Feedback weakens the attraction effect in repeated choices

초록

The present article examines how learning differs depending on the presence or absence of feedback and whether the impact of learning is sufficiently strong to override the attraction effect. The influence of repeated choices and immediate feedback was investigated in two studies. In study 1, participants were asked to choose the best quality option between two (a core set) and three (an extended set with an asymmetrically dominated option) options before and after learning, with or without feedback. Study 2 was a replication of study 1 with a more complex choice task. The results of both studies demonstrated that learning from feedback induced trade-off rule learning and decreased the magnitude of the attraction effect.
