description | The attraction
effect emerges when adding a seemingly irrelevant option (decoy) to a binary
choice shifts preference towards a target option. This suggests that choice
behaviour is dynamic, i.e., choice values are developed during deliberation,
rather than manifesting some pre-existing preference set. Whereas several
models of multialternative and multiattribute decision making consider dynamic
choice processes as crucial to explain the attraction effect, empirically
investigating the exact nature of such processes requires complementing choice
output with other data. In this study, we focused on asymmetrically dominated
decoys (i.e., decoys that are clearly dominated only by the target option) to
examine the attentional and comparative processes responsible for the
attraction effect. Through an eye-tracker paradigm, we showed that the decoy
option can affect subjects’ preferences in two different and not mutually
exclusive ways: by focusing the attention on the salient option and the
dominance attribute, and by increasing comparisons with the choice dominant
pattern. Although conceptually and procedurally distinct, both pathways for
decoy effects produce an increase in preferences for the target option, in line
with attentional and dynamic models of decision making. Eye-tracking data
provide further details to the verification of such models, by highlighting the
context-dependent nature of attention and the development of similarity-driven
competitive decisional processes. |
