J.P. Rushton’s contributions to the study of altruism

This essay describes Rushton’s work on altruism over the past 40 years. During his academic career, he changed his theoretical approach from social learning theory to trait theory to sociobiology. My essay includes five sections. The first gives an overview of Rushton’s work on altruism. The second reviews his early work based on social learning theory. His laboratory and naturalistic experiments led him to conclude that altruism could be increased by exposure to models exemplifying the behavior, and that, once engaged in, the behavior could be durable over months and generalizable across situations. The third section discusses his work on the genetic foundation of altruism with social biology including his twin studies of prosocial behaviors using different age groups of both western and Asian samples. He concluded that about 50% of the variance in prosocial behaviors is heritable. The fourth section will describe altruism as part of the general factor of personality, the apex of the personality hierarchy. The last section summarizes my review of Rushton’s work on altruism.     

The roots of human altruism

Human infants as young as 14 to 18 months of age help others attain their goals, for example, by helping them to fetch out‐of‐reach objects or opening cabinets for them. They do this irrespective of any reward from adults (indeed external rewards undermine the tendency), and very likely with no concern for such things as reciprocation and reputation, which serve to maintain altruism in older children and adults. Humans' nearest primate relatives, chimpanzees, also help others instrumentally without concrete rewards. These results suggest that human infants are naturally altruistic, and as ontogeny proceeds and they must deal more independently with a wider range of social contexts, socialization and feedback from social interactions with others become important mediators of these initial altruistic tendencies.     

Motives matter: The emotional consequences of recalled self- and other- focused prosocial acts

Past research has demonstrated that engaging in and reflecting upon past instances of prosocial behavior promote happiness. Yet, people provide help for a myriad of reasons. Do the motives for giving impact its emotional consequences? In three experiments (N?>?680), we compared the emotional outcomes of recalling a past instance of prosocial behavior motivated by self-focused and other-focused concerns. Using both between and within subjects designs, we find that recalling an instance of other-focused helping leads to higher positive affect than recalling an instance of self-focused helping. This finding was mediated by feelings of morality. The present work suggests that not all acts of kindness offer equivalent well-being benefits and that selfish motives may undermine the emotional rewards that typically follow other-focused prosocial behavior.     

Extrinsic rewards undermine altruistic tendencies in 20-month-olds

The current study investigated the influence of rewards on very young children's helping behavior. After 20-month-old infants received a material reward during a treatment phase, they subsequently were less likely to engage in further helping during a test phase as compared with infants who had previously received social praise or no reward at all. This so-called overjustification effect suggests that even the earliest helping behaviors of young children are intrinsically motivated and that socialization practices involving extrinsic rewards can undermine this tendency.     

Child protection workers’ understanding of the meaning and value of self-reflection in Estonia

This article describes an exploratory qualitative study in Estonia that focuses on how child protection workers (N = 93) perceive and understand the meaning and value of self-reflection. Participants discussed self-reflection in the context of self-analysis, motivation to improve professional performance, negative self-appraisal, and feedback from peers and clients. The findings highlight the workers’ emphasis on self-perceived weaknesses, reflecting Estonian cultural norms which eschew self-praise and focus on deficits rather than strengths and possibilities. Self-reflection was mainly associated with a cognitive process, namely learning from the experience. This study underscores the need to guide and encourage child protection workers to adopt and apply systematic and possibly less critical self-reflection so that they can strengthen their decision-making process to promote the well-being of children and their families in the child welfare system.     

Chimpanzees (Pan troglodytes) do not develop contingent reciprocity in an experimental task

Chimpanzees provide help to unrelated individuals in a broad range of situations. The pattern of helping within pairs suggests that contingent reciprocity may have been an important mechanism in the evolution of altruism in chimpanzees. However, correlational analyses of the cumulative pattern of interactions over time do not demonstrate that helping is contingent upon previous acts of altruism, as required by the theory of reciprocal altruism. Experimental studies provide a controlled approach to examine the importance of contingency in helping interactions. In this study, we evaluated whether chimpanzees would be more likely to provide food to a social partner from their home group if their partner had previously provided food for them. The chimpanzees manipulated a barpull apparatus in which actors could deliver rewards either to themselves and their partners or only to themselves. Our findings indicate that the chimpanzees’ responses were not consistently influenced by the behavior of their partners in previous rounds. Only one of the 11 dyads that we tested demonstrated positive reciprocity. We conclude that contingent reciprocity does not spontaneously arise in experimental settings, despite the fact that patterns of behavior in the field indicate that individuals cooperate preferentially with reciprocating partners.     

Donor and recipient: Social development,social interaction,and evolutionary processes

This review examines recent books on altruism and prosocial behaviour. Psychological approaches, biological approaches, and economic approaches are covered. The list of variables known to influence prosocial behaviour includes situational determinants, motivational orientations, and personality variables. Psychological theories emphasizing norms, cost-benefit calculations, and developmental factors have been used successfully to explain prosocial behaviour. Attention is given to models of helping and social and therapeutic treatment programmes. Genetic variables in prosocial behaviour are also reviewed.     

When prosocial behavior becomes altruistic: An attributional analysis

Guided by Jones and Davis’ (1965) theory of correspondent inferences, an experiment was conducted to explore the conditions under which prosocial behavior is attributed to altruism. Some 14 vignettes were constructed to vary aspects of five general dimensions believed to underlie perceptions of altruistic behavior: Benefits or costs to the actor or the actor’s close kin; benefits to the recipient of help; behavior extending beyond usual helping roles and norms; intentionality of helping; and planful versus spontaneous helping. A total of 164 respondents evaluated the actor and his or her behavior on scales measuring altruism and praiseworthiness. As hypothesized, the first four dimensions consistently predicted judgments of altruism, while the fifth did not. Strengths and shortcomings of the vignette approach are discussed, as are directions for subsequent research.     

亲社会行为的认知过程及脑神经基础

亲社会行为是指有利于他人和社会的行为,包括合作、分享、助人、安慰等。亲社会行为产生主要涉及几种认知过程:对他人行为和情绪的注意、社会信息加工、对结果的奖赏预期、社会规范表征、自我控制、以及社会信息整合与价值计算等。基于这些认知过程,研究发现,亲社会行为主要与前脑岛和前扣带回、默认网络背内侧子系统、奖赏系统以及前额叶皮层等神经区域有关,因此提出亲社会行为共同的认知-脑神经回路。未来可以对亲社会行为脑神经基础的共性、功能连接以及跨文化研究等方面做进一步探讨。     

Doing good buffers against feeling bad: Prosocial impact compensates for negative task and self-evaluations

Although evidence suggests that negative task and self-evaluations are associated with emotional exhaustion, little research has examined factors that buffer against these effects. We propose that perceived prosocial impact, the experience of helping others, compensates for negative task and self-evaluations by focusing attention on positive outcomes for others. In Study 1, perceived prosocial impact attenuated the associations of low intrinsic motivation and core self-evaluations with emotional exhaustion among professional fundraisers. Study 2 replicated these results among public sanitation employees and extended them to supervisor performance ratings. Mediated moderation analyses indicated that by protecting against emotional exhaustion, perceived prosocial impact compensated for low intrinsic motivation and core self-evaluations to predict higher performance ratings. Our studies extend theory and research on burnout, helping, and citizenship.     

Agreeableness, empathy, and helping: a person x situation perspective

This research program explored links among prosocial motives, empathy, and helping behavior. Preliminary work found significant relations among components of self-reported empathy and personality (N = 223). In Study 1, the authors examined the generality of prosocial behavior across situations and group memberships of victims (N = 622). In Study 2, empathic focus and the victim's outgroup status were experimentally manipulated (N = 87). Study 3 (N = 245) replicated and extended Study 2 by collecting measures of prosocial emotions before helping. In Study 4 (N = 244), empathic focus and cost of helping as predictors of helping behavior were experimentally manipulated. Overall, prosocial motivation is linked to (a) Agreeableness as a dimension of personality, (b) proximal prosocial cognition and motives, and (c) helping behavior across a range of situations and victims. In persons low in prosocial motivation, when costs of helping are high, efforts to induce empathy situationally can undermine prosocial behavior.     

Intrinsic motivation,external reward,and their effect on overall motivation and performance

An unresolved debate lingers concerning the effect of performance-contingent rewards on motivation and performance. Behavioral psychology and economics suggest that performance-contingent rewards improve performance. In contrast, cognitive evaluation theory predicts that performance-contingent rewards undermine motivation and performance. We discuss the predictions of these two streams and develop an experiment that resolves the limitations of previous studies by using a new measure of intrinsic motivation: self-selection into a specific area of knowledge, as revealed by choice of academic major. Students from mathematics-related and literature-related areas were selected and randomly assigned to math and English language tests. Participants received a participation fee or a performance-contingent payment in addition to a fee. Both performance-contingent rewards and intrinsic motivation improved motivation and performance, in contrast with cognitive evaluation theory’s predictions.     

ALTRUISM IN SUICIDE TERROR ORGANIZATIONS

In recent years, much has been learned about the strategic and organizational contexts of suicide attacks. However, motivations of the agents who commit them remain difficult to explain. In part this is because standard models of social learning as well as Durkheimian notions of sacrificial behavior are inadequate in the face of the actions of human bombers. In addition, the importance of organizational structures and practices in reinforcing commitment on the part of suicide recruits is an under-explored factor in many analyses. This essay examines the potential applicability of evolutionary models of altruism to the understanding of commitment to suicide on the part of terrorist organizational recruits. Three evolutionary models of sacrificial behavior in nonhuman species and many categories of human behavior are explored cross-organizationally: reciprocity, inclusive fitness theory, and induced altruism. Reciprocal altruism is unlikely to be a major motivator in suicide attacks because the costs exhibited by attackers are too high to be adequately compensated. However, the role of evolved self-deception in perceptions of personal death, and thus of rewards in the afterlife, is potentially illuminating. Inclusive fitness theory can help explain the motivations of attackers because rewards to kin often are offered by organizations to suicide recruits. However, suicide bombers also often act out of revenge for the loss of or injury to relatives, and inclusive fitness theory generally, as well as more specific theoretical models of retaliatory aggression, may not adequately account for the bombers' actions. Predictions from induced altruism theory appear to be well supported because suicide terror organizations tend to be tightly structured around practices intended to maintain and reinforce commitment though the manipulation of kinship-recognition cues.     

Factors related to helping behavior in preschool-age children

The present two studies were conducted to assess the prosocial behaviors (comforting and helping) of preschool children as a function of the race and gender of the subjects and peer confederates. Results indicated that black, preschool-age males demonstrated prosocial behaviors more often than did white males and females. These findings were discussed in terms of the confounding between race of child and father absence; that is, a disproportionate number of black children were living in fatherless homes. It was suggested that single parents may turn to their opposite-sex child for both emotional and physical support and thus the child learns comforting and helping behaviors early in life. Support for this suggestion was derived from the finding that the number of household chores assigned to a child was positively related to helping behavior. The present results also showed that comforting and helping behaviors were negatively related, suggesting that prosocial acts are not a function of a general personality trait but are situationally specific. Finally, it was noted that race and gender of the peer confederate were not factors in determining the prosocial responses of the subjects.

Perceived Neighborhood Social Resources as Determinants of Prosocial Behavior in Early Adolescence

The present study aims to develop an integrative model that links neighborhood behavioral opportunities and social resources (neighborhood cohesion, neighborhood friendship and neighborhood attachment) to prosocial (sharing, helping, empathic) behavior in early adolescence, taking into account the potential mediating role of perceived support of friends. Path analysis was used to test the proposed theoretical model in a sample of 1,145 Italian early adolescents (6th through 8th graders). More perceived opportunities and social resources in the neighborhood are related to higher levels of adolescent prosocial behavior, and this relationship is partially mediated by perceived social support from friends. The results offer promising implications for future research and intervention programs that aim to modify social systems to improve child and adolescent social competencies.     

Self‐Protective Altruism

Prosocial behavior accentuates the tension between two conflicting human motivations, self‐interest and belongingness. Responding to the needs of others may compromise self‐interest. Acting callously, however, may lead to social disproval. These antagonistic responses are existentially meaningful as belongingness and self‐esteem have been found to regulate death anxiety. In this paper I critically examine three possible hypotheses concerning the tension between egotism and prosociality from a terror management perspective. The first hypothesis, the carpe diem hypothesis, suggests that when death is salient egotistic self‐interest overrides other‐oriented responses. The second hypothesis, the norm salience hypothesis, suggests that when death is salient people will respond according to the momentarily accessible social norm. The third hypothesis, the self‐protective altruism hypothesis, argues that when the prosocial cause reminds people of their fragile, mortal nature people will turn away from helping when death is salient, but when the prosocial cause is benign death salience will increase prosocial responding.     

With a Little Help From My Friends: Bystander Context and Children's Attitude Toward Peer Helping

This experimental vignette study examined children's perceptions and evaluations of helping a peer, in the context of friendships and in the presence of by-standing peers. A total of 1246 children (8 to 12 years) reported their attitude toward helping when either friends of the helper, friends of the recipient of help, or no bystanders were present. In agreement with the competitive altruism model, children most strongly endorsed helping when friends of the helper were present compared to the other two situations. This indicates that children take reputation concerns into account when evaluating helping situations. However, in contrast to lower prosocial children, the evaluations of higher prosocial children were not influenced by the presence of by-standing peers. These children seemed to base their evaluation on increasing the recipient's welfare and less on reputation concerns of the helper.
