Who volunteers in psychology experiments? An empirical review of prosocial motivation in volunteering

The central purpose of the present research is to provide a review of social value orientation (i.e., prosocial, individualistic, and competitive orientation), a construct measured with methods rooted in game theory (i.e., decomposed games). Also, we examine its ability to predict volunteering in psychology experiments. Consistent with hypotheses, Study 1 revealed that prosocials are more likely to volunteer in psychological experiments than do individualists and competitors. Study 2 replicated these findings, and revealed also that social value orientation was strongly linked to the academic study they chose. In particular, among psychology students, prosocials (57%) was the largest group, followed by individualists (37%), and only a few competitors (6%); in contrast, among economics students, individualists appeared largest (47%), followed by prosocials (36%), and still a fairly sizeable percentage of competitors (17%). It is concluded that psychologists and economists tend to rely on samples (from their participant pools) that may systematically differ in terms of motivation and beliefs that are associated with differences in prosociality, selfishness, and competition.     

Give them what they want: The benefits of explicitness in gift exchange

Five studies show that gift recipients are more appreciative of gifts they explicitly request than those they do not. In contrast, gift givers assume that both solicited and unsolicited gifts will be equally appreciated. At the root of this dilemma is a difference of opinion about what purchasing an unsolicited gift signals: gift givers expect unsolicited gifts will be considered more thoughtful and considerate by their intended recipients than is actually the case (,  and ). In our final two studies, we highlight two boundary conditions for this effect: identifying a specific gift and using money as a gift. When gift recipients request one specific gift, rather than providing a list of possible gifts, givers become more willing to purchase the requested gift (Study 4). Further, although givers believe that recipients do not appreciate receiving money as much as receiving a solicited gift, recipients feel the opposite about these two gift options (Study 5).     

Money can’t buy love: Asymmetric beliefs about gift price and feelings of appreciation

Across three studies, we identify an asymmetry between gift-givers’ and gift-recipients’ beliefs about the link between gift price and feelings of appreciation. Gift-givers expected a positive correlation between how much they spent on a gift and the extent to which gift-recipients would appreciate the gift because gift-givers assume that more expensive gifts convey a higher level of thoughtfulness. Gift-recipients, in contrast, reported no such association between gift price and their actual feelings of appreciation. This effect occurred regardless of whether the individual’s role and the magnitude of the gift were manipulated or measured in the field. Taken together, these findings cast doubt on whether gift-givers can draw on their personal experience as gift-recipients in order to identify meaningful gifts for others.     

Implicit and explicit prosocial motivation as antecedents of volunteering: The moderating role of parenthood

We test a model proposing that having children influences motivational pathways of volunteering in the same way across two different cultures. The model posits that parents’ engagement in volunteering is driven by implicit, whereas non-parents’ engagement in volunteering is related to explicit prosocial motivation. Participants were 570 parents and non-parents from Turkey and the US (M_age = 33.7 years; 58.2% female). Results across the two cultural contexts confirmed our model. Our findings highlight the need for considering implicit prosocial motivation as an antecedent of volunteering, and underline the importance of examining parenthood as a moderator for motivations to volunteer. Avenues for further research and implications for voluntary organizations are discussed.     

If giving money to the Red Cross increases well-being,does taking money from the Red Cross increase ill-being? – Evidence from three experiments

Does having a negative impact on others decrease one’s well-being? In three separate pre-registered studies (n = 111, n = 445, & n = 447), participants engaged in a button-pushing activity for 4 min in three conditions: earning money for themselves (~60c), also earning money for the Red Cross (~15c), or also reducing the money distributed to the Red Cross (~15c). The results of the individual studies and a meta-analysis across them showed that positive impact increased well-being, but even though participants were aware of the negative impact they were having, there was no increased ill-being in the negative impact condition. In Study 3 we examined whether participants in the negative impact condition are mentally compensating by emphasizing the positive impact they are having towards science.     

From cleaning up to helping out: Parental socialization and children's early prosocial behavior

Relations between parental socialization and infants’ prosocial behavior were investigated in sixty three 18- and 30-month old children. Parents’ socialization techniques (e.g., directives, negotiation, reasoning) differed for the two age groups, as did relations between socialization and different forms of emerging prosocial behavior (helping; sharing).     

Would You Like to Round Up and Donate the Difference? Roundup Requests Reduce the Perceived Pain of Donating

Recently, some companies have begun to ask their customers to “round up” transactions to the next highest dollar and donate the difference to charity. However, little is known about how consumers respond to such an appeal. Across a series of lab experiments and one large field study, we find that consumers respond more favorably to a roundup than to a flat donation request, even when the requested amount is identical. We find evidence that the effect arises because a roundup request reduces consumers’ perceived pain of donating. Three alternative explanations are examined (i.e., objective financial cost, inattention to donation cost, and perceived novelty of the request) but not supported. This research has important implications for both companies and nonprofits seeking to increase charitable donations from consumers.     

Effects of songs with prosocial lyrics on prosocial thoughts, affect, and behavior

Previous research has shown that exposure to violent media increased aggression-related affect and thoughts, physiological arousal, and aggressive behavior as well as decreased prosocial tendencies. The present research examined the hypothesis that exposure to prosocial media promotes prosocial outcomes. Three studies revealed that listening to songs with prosocial (relative to neutral) lyrics increased the accessibility of prosocial thoughts, led to more interpersonal empathy, and fostered helping behavior. These results provide first evidence for the predictive validity of the General Learning Model [Buckley, K. E., & Anderson, C. A. (2006). A theoretical model of the effects and consequences of playing video games. In P. Vorderer, & J. Bryant, (Eds.), Playing video games: Motives responses and consequences (pp. 363-378). Mahwah, NJ: Lawrence Erlbaum Associates] for the effects of media with prosocial content on prosocial thought, feeling, and behavior.     

Violent and nonviolent video games produce opposing effects on aggressive and prosocial outcomes

Experimental studies routinely show that participants who play a violent game are more aggressive immediately following game play than participants who play a nonviolent game. The underlying assumption is that nonviolent games have no effect on aggression, whereas violent games increase it. The current studies demonstrate that, although violent game exposure increases aggression, nonviolent video game exposure decreases aggressive thoughts and feelings (Exp 1) and aggressive behavior (Exp 2). When participants assessed after a delay were compared to those measured immediately following game play, violent game players showed decreased aggressive thoughts, feelings and behavior, whereas nonviolent game players showed increases in these outcomes. Experiment 3 extended these findings by showing that exposure to nonviolent puzzle-solving games with no expressly prosocial content increases prosocial thoughts, relative to both violent game exposure and, on some measures, a no-game control condition. Implications of these findings for models of media effects are discussed.     

Identity, Reasoning, and Emotion: An Empirical Comparison of Three Sources of Moral Motivation

Prior research on moral motivation has primarily emphasized moral reasoning and moral emotion; however, identity may also play an important role. Therefore, the purpose of the present study was to examine the relative importance of prosocial identity, prosocial moral reasoning, and empathy in predicting prosocial behavior. The sample included 91 university students, ages 19–35 years (M=21.89; SD=3.01; 80% European American; 65% female). Prosocial identity and empathy, but not prosocial moral reasoning, were positively associated with overall prosocial behavior. Exploratory analyses examined how these three sources of prosocial motivation differentially related to six forms of prosocial behavior. Results suggest the importance of considering the roles of all three sources of moral motivation.     

Do you think I’m as kind as I do? The relation of adolescent narcissism with self- and peer-perceptions of prosocial and aggressive behavior

The association between narcissism and aggression has been empirically supported in adults and adolescents, but it is unclear whether narcissism might also be related to prosocial behavior. The present study investigated this issue using self- and peer-informants. Participants were 183 adolescents ages 16–19 (159 males, 24 females; 64.5% Caucasian). Of these participants, 126 (104 males, 22 females) also had peer-reported data available. Self-reported pathological narcissism was positively correlated with self-reports of both prosocial behavior and aggression, but it was not associated with peer nominations of either type of behavior. These findings indicate that adolescents with high levels of narcissism may attempt to bolster their social status by reporting engagement in both prosocial behavior and aggression. However, it appears that such individuals are ineffective at being perceived as prosocial by peers.     

Insight into toddlers’ motivation to help: From social participants to prosocial contributors

What drives toddlers’ helping behavior? And do toddlers’ helping motivations change across time? In line with Dahl and Paulus (2019), we propose that initially, toddlers start helping in ongoing chores driven by their interest in social interactions, and, later on, their helping becomes more concern based, or based on a sense of responsibility. To test this assumption, we used a longitudinal approach to examine the role that social interaction plays in toddlers’ motivation to help as they grow older. As such, we investigated whether a disruption to an experimenter during a shared chore task affected toddlers’ motivations to continue helping at the ages of 18, 21 and 24 months. Results showed that toddlers at 18 months were less likely to continue helping when the experimenter was disrupted from the shared task, in comparison to toddlers at 21 and at 24 months. These findings support the idea that toddlers develop from socially based participators into more prosocially based contributors.     

Too tired to tell the truth: Self-control resource depletion and dishonesty

The opportunity to profit from dishonesty evokes a motivational conflict between the temptation to cheat for selfish gain and the desire to act in a socially appropriate manner. Honesty may depend on self-control given that self-control is the capacity that enables people to override antisocial selfish responses in favor of socially desirable responses. Two experiments tested the hypothesis that dishonesty would increase when people’s self-control resources were depleted by an initial act of self-control. Depleted participants misrepresented their performance for monetary gain to a greater extent than did non-depleted participants (Experiment 1). Perhaps more troubling, depleted participants were more likely than non-depleted participants to expose themselves to the temptation to cheat, thereby aggravating the effects of depletion on cheating (Experiment 2). Results indicate that dishonesty increases when people’s capacity to exert self-control is impaired, and that people may be particularly vulnerable to this effect because they do not predict it.
