TL;DR: The ability of the emotion gratitude to shape costly prosocial behavior was examined in three studies employing interpersonal emotion inductions and requests for assistance and revealed that gratitude's ability to function as an incidental emotion dissipates if one is made aware of the true cause of the emotional state.

TL;DR: This article found that anger should influence automatic evaluations of outgroups because of its functional relevance to intergroup conflict and competition, whereas other negative emotions less relevant to the intergroup relations (e.g., sadness) should not.

TL;DR: Evidence is provided to demonstrate that the social emotion gratitude functions to engender cooperative economic exchange even at the expense of greater individual financial gains.

TL;DR: Findings suggest that the sex difference used to support the evolutionary view of jealousy likely represents a measurement artifact resulting from a format-induced effortful decision strategy and not an automatic, sex-specific response shaped by evolution.

TL;DR: Experimental evidence of gratitude facilitating relationship-building behaviours is provided, showing that gratitude facilitates socially inclusive behaviours, preferentially towards one's benefactor, even when those actions come at a cost to oneself.
