The authors investigated how compliance and reliance rates in a target detection task depend on the perceived difficulty and importance of the trials and on the feedback given after each trial. Results show that focusing on trial importance significantly increased participants' compliance rates while reliance rates remained stable. When no feedback was presented, ...

Yet our study showed that people typically responded fastest when toolbars are placed on the left or right side, despite the four sides being of equal distance from the center of the screen. Furthermore, responses were slowest when toolbars were placed at the bottom. We also found that participants performed significantly slower when presented with multiple toolbars and when toolbar position was unpredictable.

In our experiment, we investigated whether having e-mail senders rate the intended friendliness levels of their own messages before they write them would make them generate replies that were indeed friendlier. This manipulation was intended to make the senders more aware of their decision to write friendly or unfriendly e-mail messages and subsequently compel them to follow ...

The current study used individual difference measures to predict how much an individual can be influenced by a hedonic

Moreover, the association between smiles and lower status appears in the psychology of observers and generalizes across two forms of status: prestige and dominance. In the first study, faces of fashion models representing less prestigious apparel brands were found to be more similar to a canonical smile display than the faces of models representing more prestigious apparel brands. In a second study, after being experimentally primed with either high or low prestige fashion narratives, participants in the low prestige condition were more likely to perceive smiles in a series of photographs depicting smiling and non-smiling faces. A third study of football player photographs revealed that the faces of less dominant (smaller) football players were more similar to the canonical smile display than the faces of their physically larger counterparts. Using the same football player photog...
