Running head: EMPATHY AND HELPING IN DOGS 1 Timmy’s in the Well: Empathy and Prosocial Helping in Dogs Emily Sanford Adviser: Dr. Julia Manor, Psychology Spring 2017 EMPATHY AND HELPING IN DOGS 2 Abstract Dogs are thought to empathetically evaluate humans’ emotional states, and attend more to crying people than humming people (Custance & Mayer, 2012). However, whether dogs are empathetically motivated to provide help to humans in need is unclear. This study used a trapped-other paradigm, modified from use in research on rats, to study prosocial helping in dogs (Ben-Ami Bartal et al., 2011). A human trapped behind a door either cried or hummed, and the dog’s behavior and physiological responses, including opening and distress behaviors and heart rate variability, were recorded. Then, dogs participated in an impossible task to evaluate the strength of their emotional bond with their owner (D’Aniello et al., 2015). This study found that dogs can help humans. Dogs in the distress condition opened at the same frequency, but significantly more quickly, than dogs in the neutral condition. Behavioral coding suggests that opening may have been motivated by different mechanisms in the distress and neutral conditions. Openers in the distress condition may have been motivated by an empathetic evaluation of the owner’s emotional state with sufficient suppression of one’s personal distress. In the neutral condition, opening was not related to the emotional response and may have instead been motivated by curiosity or a desire for social contact. Results from the impossible task suggest that dogs with strong bonds to their owner are more likely to behave empathetically toward them, which is consistent with the tendency of empathy to increase with familiarity (Cialdini et al., 1997). Keywords: empathy, prosocial, heart rate variability EMPATHY AND HELPING IN DOGS 3 Acknowledgements First and foremost, I am incredibly thankful to my advisor, Professor Julia Manor, who has been instrumental in the development of my academic and research interests at Macalester College. Julia was the advisor for my first ever research project, so it is fitting that she also guided me through the completion of my honors research. Her eye for interesting scientific questions, dedication to the pursuit of knowledge, resilience in the face of challenging data, and unwavering support have been of the utmost importance as I developed my love for psychological research. I also need to thank Professor Brooke Lea. After joining his lab during my junior year, my skills as a researcher and critical thinker have expanded exponentially. My experiences working with Brooke have shaped the way that I approach research questions and tackle challenging problems in the lab. I also owe the discovery of my research interests for graduate school to his keen interventions. I definitively would not be where I am today, with the successes that I have achieved and the future I have to look forward to, without his help and guidance. The other professor whom I want to thank, and who has also been instrumental to the development of my academic interests, is Professor Chad Topaz. Since my very first semester at Macalester, Chad has been both an incredible professor as well as a reliable and caring mentor. My ability to integrate mathematics and computational thinking into my pursuit of the psychological sciences is thanks to Chad’s enthusiasm, both for the subject itself and for the continued development of my mathematical mind. This project would never have been accomplished without the help of my incredible collaborators: Emma Burt, who helped to design, run, analyze, and present the study; Malini Sharma, who was an incredibly generous volunteer of her time for data collection and video EMPATHY AND HELPING IN DOGS 4 coding; and Rainah Ward and Ali Laske, without whom the dogs would have been impossible to wrangle, and the study would have been impossible to run. I also need to thank my reviewers, Professors Mark Davis and Eric Wiertelak, for their willingness to review my research and provide insight into how it could be improved. Finally, I would like to thank my roommates, friends, and incredible family (and our dogs!) for always being supportive and continually convincing me that everything will always get done. Their love and encouragement have kept me afloat, and I am so blessed to have them all in my life. I also have to thank the good good goof-boys, the McElroy brothers, whose silliness, creativity, and sincerity have made them a constant source of light and amusement when I need them most. Great job!

Individuals’ either aggressive or prosocial characteristics and environment lead them to one type of popularity. Prosocial behaviors are actions with intention of benefiting others or society as whole with little or no personal gain and may include helping, sharing, cooperating, donating, and other voluntary works. Altruism is a type of prosocial behavior that could affect individuals' popularity. Altruism has been studied in different disciplines with the general definition of cooperative behavior that has a cost to the actor with a benefit to the receiver. From the Evolutionary Psychology perspective, altruistic behaviors decrease the fitness of individuals, which is against the principles of evolution.

  • Inclusive Fitness and the Sociobiology of the Genome
    Author's personal copy Biol Philos (2014) 29:477–515 DOI 10.1007/s10539-013-9404-0 Inclusive fitness and the sociobiology of the genome Herbert Gintis Received: 23 January 2013 / Accepted: 9 November 2013 / Published online: 1 December 2013 Ó Springer Science+Business Media Dordrecht 2013 Abstract Inclusive fitness theory provides conditions for the evolutionary success of a gene. These conditions ensure that the gene is selfish in the sense of Dawkins (The selfish gene, Oxford University Press, Oxford, 1976): genes do not and cannot sacrifice their own fitness on behalf of the reproductive population. Therefore, while natural selection explains the appearance of design in the living world (Dawkins in The blind watchmaker: why the evidence of evolution reveals a universe without design, W. W. Norton, New York, 1996), inclusive fitness theory does not explain how. Indeed, Hamilton’s rule is equally compatible with the evolutionary success of prosocial altruistic genes and antisocial predatory genes, whereas only the former, which account for the appearance of design, predominate in successful organisms. Inclusive fitness theory, however, permits a formulation of the central problem of sociobiology in a particularly poignant form: how do interactions among loci induce utterly selfish genes to collaborate, or to predispose their carriers to collaborate, in promoting the fitness of their carriers? Inclusive fitness theory, because it abstracts from synergistic interactions among loci, does not answer this question. Fitness- enhancing collaboration among loci in the genome of a reproductive population requires suppressing alleles that decrease, and promoting alleles that increase the fitness of its carriers. Suppression and promotion are effected by regulatory net- works of genes, each of which is itself utterly selfish.

  • Kin Selection
    The basics of kin selection theory Kin selection theory has its origins in attempt to unlock the puzzle of why some organisms have evolved to help other organisms of the same species. Such helping behavior is a puzzle because an organism that helps another will likely incur some reproductive cost, such as a loss of resources to allocate to its own offspring, increased mortality risk, or reductions in other components of Darwinian fitness (i.e., reproductive success). This means that any gene that increases the probability of helping behavior will reduce its frequency in future generations and ultimately will be lost unless there is some compensating reproductive benefit, i.e., some additional path by which helping behavior causes a net increase in the underlying gene's frequency. William D. Hamilton (1964) provided a pivotal insight into the evolution of altruistic helping by pointing out that altruistic acts directed toward relatives produce an important kind of reproductive compensation. By enhancing the reproduction of relatives, a help-inducing gene indirectly propagates copies of itself in those relatives. When the relatives are the helper's own offspring, most authors refer to the helping as 'parental care' and the enhancement of propagation of the helping genes is often referred to as a positive 'direct effect' of those genes. The power of Hamilton's theory was that it showed that help-inducing genes benefit in an essentially identical way when the help is directed toward non-descendant relatives, such as siblings. When the latter 'indirect' effect is sufficiently strong, the helping gene can spread (increase in frequency in the population) despite decreases in its propagation through the offspring of the individual in which it resides (i.e.

  • 1 the Natural Selection of Helping
    1 The Natural Selection of Helping 1.1 Altruism and Selfishness What is the value of moral thinking? What benefits do we get from engag- ing in this way of judging ourselves and each other? It is reasonable to assume that the answer has something to do with helpfulness and cooper- ation. In some vague manner we expect that a person who thinks of human interactions in terms of “virtue,” “obligation,” or “justice” is more likely to be a useful member of society than someone for whom these concepts are entirely alien. This natural thought will be examined in detail in chapter 4; I mention it now because one might suppose that it represents an immedi- ate barrier to the hypothesis that morality is innate. Surely, one might think, natural selection is a competitive race where the laurels go to the untamed individualist? The main goal of this first chapter is to show that this doubt is misguided. I will outline several means by which helpful, cooperative traits may evolve. But before embarking on that task we should get our thinking straight on a misleading piece of terminology. Much of the literature on the topic of how helpful behaviors might naturally emerge professes to concern the evolution of altruism, but this is a word that has, over the years, been muddied and fudged in discussions about evolution, leading to persistent confusion and erroneous conclusions in some quar- ters. In the context of this book it is important to be exact about what we mean in this respect, and so I will begin with a three-way distinction.

However, we propose that costly helping behaviors could alleviate feelings of physical burden experienced by the performers. In support of the proposal, we found in five studies that both imaginary and real helping behaviors led the performers to perceive physically c hallenging tasks as less demanding (Studies 1, 2, 3, 5), such as perceiving a steep mountain road as less steep (Study 2), a heavy carton as lighter (Study 4), and a long path as shorter (Study 5). These results challenge the conventional wisdom that helping behaviors always come at the cost of the helper and corroborate a growing body of literature showing that helping others could benefit the performer.

  • Enhancing Compassion: Social Psychological Perspectives
    1 Enhancing compassion: Social psychological perspectives Paul Condon & David DeSteno Northeastern University In press in Oxford handbook of compassion science Edited by E. Seppala, J. Doty, M. Worline, D. Cameron, S. Brown, & E. Simon-Thomas Oxford University Press Address correspondence to: Paul Condon Dept. of Psychology Northeastern University Boston, MA, 02115 [email protected] February 22, 2016 2 Enhancing compassion: Social psychological perspectives Social psychology’s contribution to the study of compassion begins with notorious examples of human failures to act compassionately. The early years of experimental social psychology were infamous for demonstrating the power of situations to hinder compassionate responses to the needs of others. The murder of Kitty Genovese in 1964, allegedly witnessed by 38 nonresponsive onlookers, sparked public and academic interest in the situational forces that cause onlookers to ignore the plights of others.1 Experimental research later confirmed that the presence of nonresponsive onlookers typically led to a reduction in helping behavior, called “the bystander effect” (Darley & Latané, 1968; Fischer et al., 2011; Latané & Nida, 1981). Further research demonstrated that situations can reduce prosocial responding even among those who have dedicated their lives to values such as compassion. In a highly cited study, seminary students under time pressure to reach a destination and deliver a lecture related to generosity and compassion were less likely to help an actor portraying a homeless man, compared with those students who were not under time pressure (Darley & Batson, 1973). Stanley Milgram’s research on obedience demonstrated the overwhelming tendency of people to obey authorities, even when authorities encouraged harm toward others, thereby overriding any impulse for compassionate action (Milgram, 1963).

Why would natural selection select for a behavior that reduces personal reproduction? As we will see, altruism can evolve when the actor and recipient carry the same genes, at one or more loci – the actor can then increase copies of their genes through the recipient’s reproduction.

Prosocial behaviors are actions with intention of benefiting others or society as whole with little or no personal gain and may include helping, cooperating, and other voluntary works. Altruism is a type of prosocial behavior that could affect individuals' popularity. Altruism has been studied in different disciplines with the general definition of cooperative behavior that has a cost to the actor with a benefit to the receiver. The common theme in all perspectives is that there is an inevitable cost for the actor with a benefit to the receiver. During the current research, surveys and vignettes were used to collect data. Participants were recruited through an online site, and were compensated for their time and participation via payment of money. As a result of the research, it was observed that helpful behaviors were highly related to the items of empathy, likeability, and popularity. Findings suggest that when gratefulness and helpful behaviors are present, individuals are rated higher in several positive qualities. The unique finding of the study is that both gratefulness and altruism are highly effective resources in interpersonal relations. Purpose of the current study is to examine the relationship between altruistic behaviors that are towards friends and popularity by the endorsement of aforementioned hypotheses and theories.
