Preferences are traditionally assumed to be stable. However, empirical evidence such as preference modulation following choices calls this assumption into question. The evolution of such postchoice preference over long time spans, even when choices have been explicitly forgotten, has so far not been studied. In two experiments, we investigated this question by using a variant of the free choice...

Political scientists frequently interpret the results of conjoint experiments as reflective majority preferences. In this article, we show that target estimand experiments, average marginal component effect (AMCE), is not well defined in these terms. Even with individually rational experimental subjects, AMCE can indicate opposite true preference majority. To this, characterize aggregation rule...

The current endeavour focuses on the notion of positive versus negative polarity preference of verbs for their direct objects. This preference has to be distinguished from a verb’s own prior polarity for the same verb, these two properties might even be inverse. Polarity preferences of verbs are extracted on the basis of a large and dependencyparsed corpus by means of statistical measures. We o...

This paper examines the determinants of the choice of financial advisors and their impact on the announcement effects of US acquirers in cross-border M&As. Two hypotheses are tested: one pertains to the acquiring firms’ home preference in selecting financial advisors, and the other relates to advisors’ experience in target countries. Evidence supports the home preference hypothesis in the selec...

Verticality plays a fundamental role in the arts, portraying concepts such as power, grandeur, or even morality; however, it is unclear whether people have an aesthetic preference for vertical stimuli. The perception of verticality occurs by integrating vestibular-gravitational input with proprioceptive signals about body posture. Thus, these signals may influence the preference for verticality...

In three experiments, rats given pairings of a neutral flavor with sucrose showed a preference for that flavor when subsequently allowed to choose between it and water. Preexposure to the flavor produced a latent inhibition effect (reduced the size of the preference) when the rats were hungry during the test (Experiments 1 and 2). Rats that were not hungry during the test failed to show latent ...

Recommender systems play an important role in supporting people getting items they like. One type of recommender systems is userbased collaborative filtering. The fundamental assumption of user-based collaborative filtering is that people who share similar preferences for common items behave similar in the future. The similarity of user preferences is computed globally on common rated items suc...

for a finite group $g$‎, ‎let $cent(g)$ denote the set of centralizers of single elements of $g$‎. ‎in this note we prove that if $|g|leq frac{3}{2}|cent(g)|$ and $g$ is 2-nilpotent‎, ‎then $gcong s_3‎, ‎d_{10}$ or $s_3times s_3$‎. ‎this result gives a partial and positive answer to a conjecture raised by a‎. ‎r‎. ‎ashrafi [on finite groups with a given number of centralizers‎, ‎algebra‎ ‎collo...
