Different brain mechanisms seem to mediate wanting and liking for the same reward. This may have implications for the modular nature of mental processes, and for understanding addictions, compulsions, free will and other aspects of desire. A few wanting and liking phenomena are presented here, together with discussion of some of these implications.

Where does normal brain or psychological function end, and pathology begin? The line can be hard to discern, making disease sometimes a tricky word. In addiction, normal ‘wanting’ processes become distorted and excessive, according to the incentive-sensitization theory. Excessive ‘wanting’ results from drug-induced neural sensitization changes in underlying brain mesolimbic systems of incentive. ‘Brain disease’ was never used by the theory, but neural sensitization changes are arguably extreme enough and problematic enough to be called pathological. This implies that ‘brain disease’ (...) can be a legitimate description of addiction, though caveats are needed to acknowledge roles for choice and active agency by the addict. Finally, arguments over ‘brain disease’ should be put behind us. Our real challenge is to understand addiction and devise better ways to help. Arguments over descriptive words only distract from that challenge. (shrink)

This review takes a historical perspective on concepts in the psychology of motivation and emotion, and surveys recent developments, debates and applications. Old debates over emotion have recently risen again. For example, are emotions necessarily subjective feelings? Do animals have emotions? I review evidence that emotions exist also as core psychological processes, which have objectively detectable features, and which can occur either with subjective feelings or without them. Evidence is offered also that studies of emotion in animals can give new (...) insights into human emotions. Beyond emotion, motivation concepts also have changed over decades, and debates still continue. Motivation was once thought in terms of aversive drives, and reward was thought of in terms of drive reduction. Motivation-as-drive concepts were largely replaced by motivation-as-incentive concepts, yet aversive drive concepts still occasionally surface in motivation neuroscience today. Among incentive motivation concepts, incentive salience is a core process, mediated by brain mesocorticolimbic systems (dopamine-related systems) and sometimes called ‘wanting’ (in quotation marks), to distinguish it from cognitive forms of desire (wanting without quotation marks). Incentive salience as ‘wanting’ is separable also from pleasure ‘liking’ for the same reward, which has important implications for several human clinical disorders. Ordinarily, incentive salience adds motivational urgency to cognitive desires, but ‘wanting’ and cognitive desires can dissociate in some conditions. Excessive incentive salience can cause addictions, in which excessive ‘wanting’ can diverge from cognitive desires. Conversely, lack of incentive salience may cause motivational forms of anhedonia in depression or schizophrenia, whereas a negatively-valenced form of ‘fearful salience’ may contribute to paranoia. Finally, negative ‘fear’ and ‘disgust’ have both partial overlap but also important neural differences. (shrink)

This article joins with others in the same issue to celebrate the career of Robert B. Zajonc who was a broad, as well as a deeply talented, psychologist. Beyond his well-known focus in social psychology, the work of Zajonc also involved, at one time or another, forays into nearly every other subfield of psychology. This article focuses specifically on his studies that extended into biopsychology, which deserve special highlighting in order to be recognized alongside his many major achievements in emotion (...) and related social topics. The biopsychological focus is offered here in the hope that all his diverse contributions be savored together when celebrating the complete psychology of Robert Zajonc. (shrink)

Heyman explains useful ways to bring addictive drug use under environmental control. We doubt that relapse is explained by drug features such as immediate reinforcement, clouding of judgment, and so forth. Relapse may require explanation in terms of enduring sensitization of incentive neural substrates, but even if its causal assumptions are wrong, Heyman's model makes useful predictions for behavioral control.

Current computational models predict reward based solely on learning. Real motivation involves that but also more. Brain reward systems can dynamically generate incentive salience, by integrating prior learned values with even novel physiological states (e.g., natural appetites; drug-induced mesolimbic sensitization) to cause intense desires that were themselves never learned. We hope future computational models may capture this too.

Arguably, emotion is always valenced—either pleasant or unpleasant—and dependent on the pleasure system. This system serves adaptive evolutionary functions; relying on separable wanting, liking, and learning neural mechanisms mediated by mesocorticolimbic networks driving pleasure cycles with appetitive, consummatory, and satiation phases. Liking is generated in a small set of discrete hedonic hotspots and coldspots, while wanting is linked to dopamine and to larger distributed brain networks. Breakdown of the pleasure system can lead to anhedonia and other features of affective disorders. (...) Eudaimonia and well-being are difficult to study empirically, yet whole-brain computational models could offer novel insights potentially linking eudaimonia to optimal metastability in the pleasure system.

The pursuit of happiness is a preoccupation for many people — and probably has been ever since the emergence of Homo sapiens sapiens. The scientific understanding of the brain basis of happiness and its pursuit is, however, still in its infancy. Here we focus on recent scientific research on the closely related concepts of pleasure and desire, and discuss their underlying neural mechanisms and their roles in happiness. We also speculate on potential contributions of the brain's default networks to orchestrating (...) cognitive aspects of meaningfulness that are important to happiness. Finally, we discuss how the lack of pleasure, anhedonia, is a central feature of emotional disorders such as depression and thus perhaps the most important obstacle to happiness for many people.

In this paper the authors present a description and reflective analysis of an underdeveloped aspect of legal ethics education: judicial ethics. Part I provides an introduction to Canada's National Judicial Institute and its early attempts to design and deliver judicial ethics education programmes. Part II then suggests that in the last few years a second generation of judicial ethics education has emerged, generating a more systemic and contextually sophisticated pedagogical agenda. Finally, in Part III, the authors argue in favour of (...) even more challenging judicial ethics programmes that will enable judges to develop an enhanced ethical identity. (shrink)

This article focuses on the substantial progress in understanding the psychology and neurobiology of sensory pleasure that has been made over the last decade. The link between pleasure and happiness has a long history in psychology. The growing evidence for the importance of affect in psychology and neuroscience shows a scientific account that involves hedonic pleasures and displeasures. A neurobiological understanding is required of how positive and negative effects are balanced in the brain. The article surveys developments in understanding brain (...) mechanisms of pleasure. It identifies a number of brain regions that are important in the brain's hedonic networks, and speculated on potential interaction with eudaimonic networks. The scientific study of pleasure and affect demonstrates the evolution of emotions and affective expressions, and suggests that these are adaptive responses to environmental situations. (shrink)

Two issues are raised. (1) What is the nature of the drug effect Heyman thinks confers value to drugs? (2) What is the evidence that drug use decreases the value of drugs and of conventional incentives over the long-term? There is considerable evidence for the opposite; a persistent increase in the sensitivity of neural systems that mediate drug value.

In the United States, at least 6% of all hospital beds are in the intensive care unit or coronary care unit. The cost of treating a patient in an intensive care unit averages from $2,000 to $3,500 per day. At least 10–40% of intensive care patients will not survive to hospital discharge. Today, every major category of disease may be found in the modern ICU; common diagnoses are septicemia, postsurgical complications, cerebrovascular accidents, gastrointestinal bleeding, neoplasia, and respiratory failure. ICUs employ (...) some of the most sophisticated medical technology, routinely monitoring the cardiopulmonary performance of patients and often providing assisted ventilation. ICUs are high intensity in terms of their staffing, involving 24-hour physician supervision and nurse:patient ratios from 1:3 to 1:1. (shrink)

The question 'Why should I obey the law?' introduces a contemporary puzzle that is as old as philosophy itself. The puzzle is especially troublesome if we think of cases in which breaking the law is not otherwise wrongful, and in which the chances of getting caught are negligible. Philosophers from Socrates to H.L.A. Hart have struggled to give reasoned support to the idea that we do have a general moral duty to obey the law but, more recently, the greater number (...) of learned voices has expressed doubt that there is any such duty, at least as traditionally conceived.

Mass-marketing frauds are on the increase. Given the amount of monies lost and the psychological impact of MMFs there is an urgent need to develop new and effective methods to prevent more of these crimes. This paper reports the early planning of automated methods our interdisciplinary team are developing to prevent and detect MMF. Importantly, the paper presents the ethical and social constraints involved in such a model and suggests concerns others might also consider when developing automated systems.

BackgroundThe Arab population in Israel is a minority ethnic group with its own distinct cultural subgroups. Minority populations are known to underutilize genetic tests and counseling services, thereby undermining the effectiveness of these services among such populations. However, the general and culture-specific reasons for this underutilization are not well defined. Moreover, Arab populations and their key cultural-religious subsets (Muslims, Christians, and Druze) do not reside exclusively in Israel, but are rather found as a minority group in many European and North (...) American countries. Therefore, focusing on the Arab population in Israel allows for the examination of attitudes regarding genetic testing and counseling among this globally important ethnic minority population.MethodsWe used a qualitative research method, employing individual interviews with 18 women of childbearing age from three religious subgroups (i.e., Druze, Muslim, and Christian) who reside in the Acre district, along with focus group discussions with healthcare providers (HCPs; 9 nurses and 7 genetic counselors) working in the same geographical district.ResultsA general lack of knowledge regarding the goals and practice of genetic counseling resulting in negative preconceptions of genetic testing was identified amongst all counselees. Counselors’ objective of respecting patient autonomy in decision-making, together with counselees’ misunderstanding of genetic risk data, caused uncertainty, frustration, and distrust. In addition, certain interesting variations were found between the different religious subgroups regarding their attitudes to genetic counseling.ConclusionsThe study highlights the miscommunications between HCPs, particularly counselors from the majority ethno-cultural group, and counselees from a minority ethno-cultural group. The need for nuanced understanding of the complex perspectives of minority ethno-cultural groups is also emphasized. Such an understanding may enhance the effectiveness of genetic testing and counseling among the Arab minority group while also genuinely empowering the personal autonomy of counselees from this minority group in Israel and other countries.

This is the first book to offer the best essays, articles, and speeches on ethics and intelligence that demonstrate the complex moral dilemmas in intelligence collection, analysis, and operations. Some are recently declassified and never before published, and all are written by authors whose backgrounds are as varied as their insights, including Robert M. Gates, former Director of the Central Intelligence Agency; John P. Langan, the Joseph Cardinal Bernardin Professor of Catholic Social Thought at the Kennedy Institute of Ethics, Georgetown (...) University; and Loch K. Johnson, Regents Professor of Political Science at the University of Georgia and recipient of the Owens Award for contributions to the understanding of U.S. intelligence activities. Creating the foundation for the study of ethics and intelligence by filling in the gap between warfare and philosophy, this is a valuable collection of literature for building an ethical code that is not dependent on any specific agency, department, or country.

An empirical study published in the Journal of Personality and Social Psychology (King, L. A. and C. K. Nappa: 1998, Journal of Personality and Social Psychology 75(1), 156-165) concludes that people generally believe meaning and happiness are essential elements of the good life, whereas money is relatively unimportant. Yet, the authors also state that although "we do know what it takes to make a good life...we still behave as if we did not." The authors are suggesting that despite a general (...) belief that money is relatively unimportant in creating happiness, many people continue to focus their behaviors on increasing income and wealth. This is the classic conflict between the folk wisdom that money cannot buy happiness, on the one hand, and a continued focus by many people on achieving material success on the other. The issue is of particular importance to business professionals, not only because profit maximization is the central focus of business, but also because college students often pursue business as a profession for the express purpose of maximizing personal income and wealth. In the business world a focus on personal financial success is the norm. Wealth and income are honored. The purpose of this is to critically analyze psychological studies comparing happiness and financial success. The results are then contrasted with philosophical wisdom and religious writings comparing happiness and money. The intent is to determine whether psychological studies provide incremental insights into the connection between financial success and happiness. (shrink)

In the course of describing the events of the 160s b.c.e., 2 Maccabees presents the texts of four letters: the Seleucid general Lysias to the Jews granting some concessions and referring their other demands to the king ; two letters of Antiochus, to Lysias and to the Jews, granting various concessions; and Roman envoys to the Jews endorsing Lysias’ concessions. The third and fourth letters have at their ends the same date, 15 Xanthikos of Seleucid year 148, c. March 164 (...) b.c.e. The second has no date. The first, Lysias’ letter, is dated ἔτους ἑκατοστοῦ τεσσαρακοστοῦ ὀγδόου, διοσκορινθίου τετράδι καὶ εἰκάδι: year 148 on the 24th of a month; but the month name, standardly printed as Διὸς Κορινθίου, is impossible.

If you think that semantic minimalism is the only alternative to contextualism but you’d rather do without Cappelen and Lepore’s mysteriously minimal “propositions,” you can. You just have to recognize that being semantically incomplete does not make a sentence context-sensitive. You don’t have to go through the ritual of repeatedly incanting things like this: “John is ready” expresses the proposition that John is ready. Instead, you can opt for Radical Minimalism and suppose that “John is ready” and its ilk fall (...) short of semantically expressing propositions – their semantic contents are propositional “radicals.” Now C&L think they’ve addressed Radical Minimalism and offered objections to it. So they find it strange and bizarre that I think they haven’t. In fact, they persist in confusing semantic incompleteness with context sensitivity. If they appreciated the difference, they might even welcome the opportunity to adopt a form of semantic minimalism that does without the minimal propositions that everyone but them find incredible (pun intended).

This paper argues that fitness is most usefully understood as those properties of organisms that are explanatory of survival in the broadest sense, not merely descriptive of reproductive success. Borrowing from Rosenberg and Bouchard , fitness in this sense is ecological in that it is defined by the interactions between organisms and environments. There are three sorts of ecological fitness: the well-documented ability to compete, the ability to cooperate , and a third sense of fitness that has received insufficient attention (...) in evolutionary theory, the ability to construct. Following Lotka, it can be understood thermodynamically as the ability to maintain or enlarge the energy-circulating capacity of an ecosystem. An organism that does this could end with its gene frequency unchanged but its probability of survival enhanced since it would sustain or increase the total carrying capacity of its ecosystem. Photosynthesizers and other autotrophs are obvious candidates for organisms that are fit in the constructive sense, but any organisms, including heterotrophs, can exhibit constructive fitness if they have some mechanism for channeling external flows of free energy into their ecosystems. I will briefly examine the prospects for the human species in the light of these considerations. (shrink)

This study seeks to understand the subjective experience or lived world typical of patients with Parkinson’s disease. It uses qualitative methodology, grounded in a hermeneutic-phenomenological perspective, to consider lived experience in a small sample of 7 individuals. The analysis identified four themes that appear to be characteristic of the experience of PD: A) Denial, B) Emotion and symptom expression, C) Volitional and spontaneous action, and D) Alteration of temporal perspective. Concepts from existential-phenomenological philosophy were used to reflect upon these themes (...) to achieve a synthetic account of the subjective experience of PD. The findings of the study are compared to other findings in the phenomenological literature, and suggestions for further research are posed. (shrink)

In my commentary on Herman Cappelen and Ernie Lepore’s aptly titled book, Insensitive Semantics, I stake out a middle ground between their version of Semantic Minimalism and Contextualism. My kind of Semantic Minimalism does without the “minimal propositions” posited by C&L. It allows that some sentences do not express propositions, even relative to contexts. Instead, they are semantically incomplete. It is not a form of contextualism, since being semantically incomplete is not a way of being context-sensitive. In their reply to (...) my commentary, C&L seem to miss this point. Exaggerating the force of their slippery slope argument, they continue to suppose that contextualism is the only alternative to their version of minimalism. They contend that I haven’t replied to their central criticism, but in fact they haven’t replied to mine. (shrink)
