The paradox of power: The relationship between self-esteem and gratitude.

In contrast to earlier research, the three studies reported here find that the most powerful individuals are also the most grateful, and that self-esteem plays a role in explaining this relationship. Study 1a (N = 109) reveals a strong, positive relationship between individuals' perceived power and gratitude. Study 1b (N = 194) replicates this and finds that self-esteem mediates this positive power-gratitude relationship. Study 2 (N = 212) manipulates power and shows its downstream effects on gratitude through self-esteem, again providing support for the positive relationship of power to gratitude through self-esteem. We argue that because gratitude is predicated on recognition that others value oneself, power amplifies rather than undercuts feelings of gratitude. We discuss possible boundary conditions.

Gratitude and Loneliness: Enhancing Health and Well-Being in Older Adults.

We experimentally investigated gratitude's impact on loneliness and health in older adults. Participants were assigned to a daily gratitude writing exercise (treatment group) or a control group. Self-reported loneliness and health (i.e., subjective well-being, subjective health, health symptoms) were measured daily over a 3-week period. In support of our hypotheses, within-person variability in gratitude predicted differences in loneliness and health. Furthermore, those in the treatment group showed stronger cumulative effects of gratitude on loneliness and health symptoms when aggregated across the 20-day study. Additionally, a series of conditional, multilevel indirect effect models found that loneliness acted as a mechanism for gratitude's differential impact on subjective well-being and health symptoms across conditions. Taken together, this study provides initial evidence that a simple gratitude exercise can strengthen associations among daily gratitude and loneliness and, consequently, improve health, for older adults.

Warm thanks: gratitude expression facilitates social affiliation in new relationships via perceived warmth.

Recent theorizing on the nature and function of gratitude (the find-remind-and-bind theory; Algoe, 2012) stipulates that expressing gratitude should serve to alert previously unacquainted peers to the potential for a high-quality social bond (i.e., a find function). Although the logic of this premise is supported by extant research, it has not, as yet, been tested empirically. In the current study, participants received a note from a previously unacquainted peer that contained an expression of gratitude (or did not) with regard to prior benefits provided by the participant. After providing ratings of the peer and ostensibly completing the study, participants were given an opportunity to spontaneously give their contact information to the peer, which served as a behavioral measure of affiliation. In line with the proposed find function of gratitude expressions, recipients of expressions of gratitude were more likely to extend the effort to continue the relationship with the novel peer by providing that peer with a means to contact them. This experiment also provided evidence that perceptions of interpersonal warmth (e.g., friendliness, thoughtfulness) serve as the mechanism via which gratitude expressions facilitate affiliation: insofar as gratitude expressions signaled interpersonal warmth of the expresser, they prompted investment in the burgeoning social bond. As such, these findings provide the first empirical evidence regarding 1 of the 3 central premises of the find-remind-and-bind theory of gratitude (Algoe, 2012) in the context of novel relationships.

Gratitude: prompting behaviours that build relationships.

The emotion gratitude is argued to play a pivotal role in building and maintaining social relationships. Evidence is accumulating that links gratitude to increases in relationship satisfaction. Yet, there is currently little evidence for how gratitude does this. The present paper provides experimental evidence of gratitude facilitating relationship-building behaviours. Study 1 provides evidence that gratitude promotes social affiliation, leading one to choose to spend time with a benefactor. Study 2 offers further evidence of gratitude's ability to strengthen relationships by showing that gratitude facilitates socially inclusive behaviours, preferentially towards one's benefactor, even when those actions come at a cost to oneself.

Gratitude as moral sentiment: emotion-guided cooperation in economic exchange.

Economic exchange often pits options for selfish and cooperative benefit against one another. Decisions favoring communal profit at the expense of self-interest have traditionally been thought to stem from strategic control aimed at tamping down emotional responses centered on immediate resource acquisition. In the present article, evidence is provided to argue against this limited view of the role played by emotion in shaping prosociality. Findings demonstrate that the social emotion gratitude functions to engender cooperative economic exchange even at the expense of greater individual financial gains. Using real-time inductions, increased gratitude is shown to directly mediate increased monetary giving within the context of an economic game, even where such giving increases communal profit at the expense of individual gains. Moreover, increased giving occurred regardless of whether the beneficiary was a known individual or complete stranger, thereby removing the possibility that it stemmed from simple awareness of reciprocity constraints.

Jealousy and the threatened self: getting to the heart of the green-eyed monster.

Several theories specifying the causes of jealousy have been put forth in the past few decades. Firm support for any proposed theory, however, has been limited by the difficulties inherent in inducing jealousy and examining any proposed mediating mechanisms in real time. In support of a theory of jealousy centering on threats to the self-system, 2 experiments are presented that address these past limitations and argue for a model based on context-induced variability in self-evaluation. Experiment 1 presents a method for evoking jealousy through the use of highly orchestrated social encounters and demonstrates that threatened self-esteem functions as a principal mediator of jealousy. In addition to replicating these findings, Experiment 2 provides direct evidence for jealousy as a cause of aggression. The ability of the proposed theory of jealousy to integrate other extant findings in the literature is also discussed.

Constraining accommodative homunculi in evolutionary explorations of jealousy: a reply to Barrett et al. (2006).

This article responds to a critique by H. C. Barrett, D. A. Frederick, M. G. Haselton, and R. Kurzban, wherein it is argued that manipulations of cognitive constraints cannot be used to test general evolutionary hypotheses regarding the architecture of mind. In making this argument, Barrett et al. focus on what they believe to be faulty logic in D. DeSteno, M. Y. Bartlett, J. Braverman, and P. Salovey's use of such techniques to examine proposed sex differences in jealousy. In presenting their argument, however, Barrett et al. appear to disregard central findings presented in DeSteno et al. (2002) and, in so doing, fail to grasp the interrelations among findings that might readily address their concerns. Here, the authors present arguments for why and when manipulations of cognitive resources may prove useful in investigating evolved psychological mechanisms and, in so doing, situate their use within the ongoing debate concerning evolved sex differences in jealousy.

Gratitude and prosocial behavior: helping when it costs you.

The ability of the emotion gratitude to shape costly prosocial behavior was examined in three studies employing interpersonal emotion inductions and requests for assistance. Study 1 demonstrated that gratitude increases efforts to assist a benefactor even when such efforts are costly (i.e., hedonically negative), and that this increase differs from the effects of a general positive affective state. Additionally, mediational analyses revealed that gratitude, as opposed to simple awareness of reciprocity norms, drove helping behavior. Furthering the theory that gratitude mediates prosocial behavior, Study 2 replicated the findings of Study 1 and demonstrated gratitude's ability to function as an incidental emotion by showing it can increase assistance provided to strangers. Study 3 revealed that this incidental effect dissipates if one is made aware of the true cause of the emotional state. Implications of these findings for the role of gratitude in building relationships are discussed.

Prejudice from thin air: The effect of emotion on automatic intergroup attitudes.

Two experiments provide initial evidence that specific emotional states are capable of creating automatic prejudice toward outgroups. Specifically, we propose 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 intergroup relations (e.g., sadness) should not. In both experiments, after minimal ingroups and outgroups were created, participants were induced to experience anger, sadness, or a neutral state. Automatic attitudes toward the in- and outgroups were then assessed using an evaluative priming measure (Experiment 1) and the Implicit Association Test (Experiment 2). As predicted, results showed that anger created automatic prejudice toward the outgroup, whereas sadness and neutrality resulted in no automatic intergroup bias. The implications of these findings for emotion-induced biases in implicit intergroup cognition in particular, and in social cognition in general, are considered.

Sex differences in jealousy: evolutionary mechanism or artifact of measurement?

Two studies are presented that challenge the evidentiary basis for the existence of evolved sex differences in jealousy. In opposition to the evolutionary view, Study I demonstrated that a sex difference in jealousy resulting from sexual versus emotional infidelity is observed only when judgments are recorded using a forced-choice response format. On all other measures, no sex differences were found; both men and women reported greater jealousy in response to sexual infidelity. A second study revealed that the sex difference on the forced-choice measure disappeared under conditions of cognitive constraint. These findings suggest that the sex difference used to support the evolutionary view of jealousy (e.g., D. M. Buss, R. Larsen, D. Westen, & J. Semmelroth, 1992; D. M. Buss et al., 1999) likely represents a measurement artifact resulting from a format-induced effortful decision strategy and not an automatic, sex-specific response shaped by evolution.
