Affective Computing The IEEE Global Initiative on Ethics of Autonomous and Intelligent Systems Affective Computing Affect is a core aspect of intelligence. Drives and emotions, such as excitement and depression, are used to coordinate action throughout intelligent life, even in species that lack a nervous system. Emotions are one mechanism that humans evolved to accomplish what needs to be done in the time available with the information at hand—to satisfice. Emotions are not an impediment to rationality; arguably they are integral to rationality in humans. Humans create and respond to both positive and negative emotional influence as they coordinate their actions with other individuals to create societies. Autonomous and intelligent systems (A/IS) are being designed to simulate emotions in their interactions with humans in ways that will alter our societies. A/IS should be used to help humanity to the greatest extent possible in as many contexts as are appropriate. While A/IS have tremendous potential to effect positive change, there is also potential that artifacts used in society could cause harm either by amplifying, altering, or even dampening human emotional experience. Even rudimentary versions of synthetic emotions, such as those already in use within nudging systems, have already altered the perception of A/IS by the general public and public policy makers. This chapter of Ethically Aligned Design addresses issues related to emotions and emotion- like control in interactions between humans and design of A/IS. We have put forward recommendations on a variety of topics: considering how affect varies across human cultures; the particular problems of artifacts designed for caring and private relationships; considerations of how intelligent artifacts may be used for “nudging”; how systems can support human flourishing; and appropriate policy interventions for artifacts designed with inbuilt affective systems.

  • Roles of Moral Emotions and Gender
    International Journal of Communication 14(2020), 4890–4912 1932–8036/20200005 An Examination of Information Behaviors Surrounding Controversial Sociopolitical Issues: Roles of Moral Emotions and Gender CHENG HONG California State University, Sacramento, USA WEITING TAO University of Miami, USA WAN-HSIU SUNNY TSAI University of Miami, USA BO RA YOOK Fairfield University, USA Given the emotion-laden nature and moral considerations of controversial sociopolitical issues, this study examines two key antecedents of publics’ information behaviors about controversial sociopolitical issues. We focus on the underresearched emotional dimension by investigating the effects of moral emotions induced by such issues as well as a key demographic factor, gender, on publics’ information behaviors toward such issues. Results of this study highlight the significant influence of moral emotions and expand theoretical understanding of public advocacy on highly divisive issues. Keyword: moral emotions, controversial sociopolitical issues, gender, information behaviors In today’s volatile political climate, controversial sociopolitical issues such as abortion, immigration, and LGBTQ rights have generated heated public debates and shaped public opinion. When exposed to these issues, people of different stances and levels of issue involvement tend to take, select, and give issue-related information differently (Kim & Grunig, 2011; Ni & Kim, 2009). Drawing insights from the situational theory of problem solving (STOPS; Kim & Grunig, 2011), literature on information avoidance (Sweeny, Melnyk, Miller, & Shepperd, 2010), and theories of moral emotions (Rozin, Lowery, Imada, & Haidt, 1999), this study focuses on three key information behaviors—information seeking, avoidance, and forwarding—as the determinants of citizens’ engagement in civic and political conversation. This study focuses on these three behaviors for two important reasons.

  • DISGUST: Features and SAWCHUK and Clinical Implications
    Journal of Social and Clinical Psychology, Vol. 24, No. 7, 2005, pp. 932-962 OLATUNJIDISGUST: Features AND SAWCHUK and Clinical Implications DISGUST: CHARACTERISTIC FEATURES, SOCIAL MANIFESTATIONS, AND CLINICAL IMPLICATIONS BUNMI O. OLATUNJI University of Massachusetts CRAIG N. SAWCHUK University of Washington School of Medicine Emotions have been a long–standing cornerstone of research in social and clinical psychology. Although the systematic examination of emotional processes has yielded a rather comprehensive theoretical and scientific literature, dramatically less empirical attention has been devoted to disgust. In the present article, the na- ture, experience, and other associated features of disgust are outlined. We also re- view the domains of disgust and highlight how these domains have expanded over time. The function of disgust in various social constructions, such as cigarette smoking, vegetarianism, and homophobia, is highlighted. Disgust is also becoming increasingly recognized as an influential emotion in the onset, maintenance, and treatment of various phobic states, Obsessive–Compulsive Disorder, and eating disorders. In comparison to the other emotions, disgust offers great promise for fu- ture social and clinical research efforts, and prospective studies designed to improve our understanding of disgust are outlined. The nature, structure, and function of emotions have a rich tradition in the social and clinical psychology literature (Cacioppo & Gardner, 1999). Although emotion theorists have contested over the number of discrete emotional states and their operational definitions (Plutchik, 2001), most agree that emotions are highly influential in organizing thought processes and behavioral tendencies (Izard, 1993; John- Preparation of this manuscript was supported in part by NIMH NRSA grant 1F31MH067519–1A1 awarded to Bunmi O.

  • About Emotions There Are 8 Primary Emotions. You Are Born with These
    About Emotions There are 8 primary emotions. You are born with these emotions wired into your brain. That wiring causes your body to react in certain ways and for you to have certain urges when the emotion arises. Here is a list of primary emotions: Eight Primary Emotions Anger: fury, outrage, wrath, irritability, hostility, resentment and violence. Sadness: grief, sorrow, gloom, melancholy, despair, loneliness, and depression. Fear: anxiety, apprehension, nervousness, dread, fright, and panic. Joy: enjoyment, happiness, relief, bliss, delight, pride, thrill, and ecstasy. Interest: acceptance, friendliness, trust, kindness, affection, love, and devotion. Surprise: shock, astonishment, amazement, astound, and wonder. Disgust: contempt, disdain, scorn, aversion, distaste, and revulsion. Shame: guilt, embarrassment, chagrin, remorse, regret, and contrition. All other emotions are made up by combining these basic 8 emotions. Sometimes we have secondary emotions, an emotional reaction to an emotion. We learn these. Some examples of these are: o Feeling shame when you get angry. o Feeling angry when you have a shame response (e.g., hurt feelings). o Feeling fear when you get angry (maybe you’ve been punished for anger). There are many more. These are NOT wired into our bodies and brains, but are learned from our families, our culture, and others. When you have a secondary emotion, the key is to figure out what the primary emotion, the feeling at the root of your reaction is, so that you can take an action that is most helpful. .

  • 1 the Development of Empathy: How, When, and Why Nicole M. Mcdonald & Daniel S. Messinger University of Miami Department Of
    1 The Development of Empathy: How, When, and Why Nicole M. McDonald & Daniel S. Messinger University of Miami Department of Psychology 5665 Ponce de Leon Dr. Coral Gables, FL 33146, USA 2 Empathy is a potential psychological motivator for helping others in distress. Empathy can be defined as the ability to feel or imagine another person’s emotional experience. The ability to empathize is an important part of social and emotional development, affecting an individual’s behavior toward others and the quality of social relationships. In this chapter, we begin by describing the development of empathy in children as they move toward becoming empathic adults. We then discuss biological and environmental processes that facilitate the development of empathy. Next, we discuss important social outcomes associated with empathic ability. Finally, we describe atypical empathy development, exploring the disorders of autism and psychopathy in an attempt to learn about the consequences of not having an intact ability to empathize. Development of Empathy in Children Early theorists suggested that young children were too egocentric or otherwise not cognitively able to experience empathy (Freud 1958; Piaget 1965). However, a multitude of studies have provided evidence that very young children are, in fact, capable of displaying a variety of rather sophisticated empathy related behaviors (Zahn-Waxler et al. 1979; Zahn-Waxler et al. 1992a; Zahn-Waxler et al. 1992b). Measuring constructs such as empathy in very young children does involve special challenges because of their limited verbal expressiveness. Nevertheless, young children also present a special opportunity to measure constructs such as empathy behaviorally, with less interference from concepts such as social desirability or skepticism.

Foreword In 1988, more than half of Tennessee’s school systems joined together and filed a lawsuit charging the state with failing to fund all systems, rich and poor, equitably, and in 1993, they won. In the meantime and after two years of deliberation, the Tennessee General Assembly adopted a new funding formula as part of the Education Improvement Act (EIA) of 1992. The plaintiffs were not entirely satisfied with that remedy and challenged it on three bases: it did not solve the problem of inequity among the systems in teachers’ salaries, it should be funded immediately and not phased in over six years as the legislature planned, and it did not provide adequate funds to bring all school buildings up to modern standards.

  • Moral Emotions As Determinants of Third-Party Punishment: Anger, Guilt, and the Functions of Altruistic Sanctions
    Judgment and Decision Making, Vol. 4, No. 7, December 2009, pp. 543–553 Moral emotions as determinants of third-party punishment: Anger, guilt, and the functions of altruistic sanctions Rob M. A. Nelissen∗ and Marcel Zeelenberg Tilburg University, the Netherlands Abstract Third-party punishment has recently received attention as an explanation for human altruism. Feelings of anger in response to norm violations are assumed to motivate third-party sanctions, yet there is only sparse and indirect support for this idea. We investigated the impact of both anger and guilt feelings on third-party sanctions. In two studies both emotions were independently manipulated. Results show that anger and guilt independently constitute sufficient but not necessary causes of punishment. Low levels of punishment are observed only when neither emotion is elicited. We discuss the implications of these findings for the functions of altruistic sanctions. Keywords: third-party punishment, social norms, emotions, decision-making. 1 Introduction own (Haidt, 2003).
