Discrete choice experiments—selecting the best and/or worst from a set of options—are increasingly used to provide more efficient and valid measurement of attitudes or preferences than conventional methods such as Likert scales. Discrete choice data have traditionally been analyzed with random utility models that have good measurement properties but provide limited insight into cognitive processes. We extend a well-established cognitive model, which has successfully explained both choices and response times for simple decision tasks, to complex, multi-attribute discrete choice data. The (...) fits, and parameters, of the extended model for two sets of choice data (involving patient preferences for dermatology appointments, and consumer attitudes toward mobile phones) agree with those of standard choice models. The extended model also accounts for choice and response time data in a perceptual judgment task designed in a manner analogous to best–worst discrete choice experiments. We conclude that several research fields might benefit from discrete choice experiments, and that the particular accumulator-based models of decision making used in response time research can also provide process-level instantiations for random utility models.

Not illustrated. 1873 edition. Excerpt:...but it does not follow that knowledge is not good. It is more needful that I should be a good Christian, than that I should be able to make good shoes. But this, too, is needful for one who is a shoemaker, and his Christianity is to show (...) itself in his earthly calling, and not to be an excuse for unskilfulness therein. And here, too, the case is similar. It is true that knowledge puffs up, that is, superficial knowledge, the appearance of knowledge, where its reality and solidity are wanting; while true knowledge, and earnest genuine research, makes a man humble and modest. For the more we learn, the more we perceive what we owe to others, and the more we know, the more we perceive how little we know. Heal research, moreover, is impossible without self-denial, devotion, and a feeling for truth which will not be ashamed to confess its errors to itself and others. To investigate is a moral labour, and not a mere exercise of the mind. True science cannot be separated from morality, and true morality has always a religious root, even when this is unconfessed. When we investigate, too, we owe our best discoveries to God; our best possessions are a gift from above. When Pythagoras had discovered his famous geometrical theorem concerning the squares of a right-angled triangle, he sacrificed a hecatomb to the gods. And Kepler concluded his famous work on the motion of the planets with hearty thanksgiving to God. The true disciples of science have ever been the pupils of that heavenly wisdom of which St. James says that it is " peaceable, gentle, easy to be entreated, without partiality, and without hypocrisy." And does not all knowledge, when we go deeply into it, lead is to God? What Bacon said of philosophy, that " a little inclineth mens minds... (shrink)
