The first-member heuristic: Group members labeled "first" influence judgment and treatment of groups.

People often make judgments about a group (e.g., immigrants from a specific country) based on information about a single group member.

Mental Simulation of Visceral States Affects Preferences and Behavior.

Preferences and behavior are heavily influenced by one's current visceral experience, yet people often fail to anticipate such effects. Although research suggests that this gap is difficult to overcome-to act as if in another visceral state-research on mental simulation has demonstrated that simulations can substitute for experiences, albeit to a weaker extent. We examine whether mentally simulating visceral states can impact preferences and behavior.

Only one small sin: How self-construal affects self-control.

Past research has shown that self-construal can influence self-control by reducing interdependent people's impulsivity in the presence of peers. We broaden these findings by examining the hypothesis that an interdependent (vs. independent) self-construal fosters self-control even in the absence of peers and for non-impulsive decisions.

Being observed magnifies action.

We test the hypothesis that people, when observed, perceive their actions as more substantial because they add the audience's perspective to their own perspective. We find that participants who were observed while eating (Study 1) or learned they were observed after eating (Study 2) recalled eating a larger portion than unobserved participants. The presence of others magnified both desirable and undesirable actions.
