Freud's early attempts to account for repression and for the occurrence of neurotic symptoms in terms of detachable and displaceable quantities of affect?charge (cathexis) has continued to be a basic aspect of psychoanalytic theory. This is unfortunate since the account is inadequate and its central concept, that of a quantity of energy, is unsuited to the task at hand. We see that, despite the appropriateness of describing neurotic behavior in dynamic/economic terms, the use of energy concepts on the theoretical level (...) is an explanatory dead?end. (shrink)

This article argues that we could improve the design of research protocols by developing an awareness of and a responsiveness to the social contexts of all the actors in the research enterprise, including subjects, investigators, sponsors, and members of the community in which the research will be conducted. “Social context” refers to the settings in which the actors are situated, including, but not limited to, their social, economic, political, cultural, and technological features. The utility of thinking about social contexts is (...) introduced and exemplified by the presentation of a hypothetical case in which one central issue is limitation of the probability of injury to subjects by selection of individuals who are not expected to live long enough for the known risks of the study to become manifest as harms. Benefits of such considerations may include enhanced subject satisfaction and cooperation, community acceptance, and improved data quality, among other desirable consequences. (shrink)

In my contribution to this volume, I (BHS) comment on on the stultifying rhetoric of contemporary analytic moral theory as illustrated in Judith Jarvis Thomson's Tanner Lectures, with particular reference to Thomson's anxieties about the moral relativism exhibited by college freshman and to her efforts--quite strained, in my view, and inevitably unsuccessful--to demonstrate the existence of objective judgments in matters of morality and taste .

Production and comprehension have long been viewed as inseparable components of language. The study of vision, by contrast, has centered almost exclusively on comprehension. Here we investigate drawing—the most basic form of visual production. How do we convey concepts in visual form, and how does refining this skill, in turn, affect recognition? We developed an online platform for collecting large amounts of drawing and recognition data, and applied a deep convolutional neural network model of visual cortex trained only on natural (...) images to explore the hypothesis that drawing recruits the same abstract feature representations that support natural visual object recognition. Consistent with this hypothesis, higher layers of this model captured the abstract features of both drawings and natural images most important for recognition, and people learning to produce more recognizable drawings of objects exhibited enhanced recognition of those objects. These findings could explain why drawing is so effective for communicating visual concepts, they suggest novel approaches for evaluating and refining conceptual knowledge, and they highlight the potential of deep networks for understanding human learning.

The “reproductive suppression hypothesis” states that the strong desire of adolescent girls in our culture to control their weight may reflect the operation of an adaptive mechanism by which ancestral women controlled the timing of their sexual maturation and hence first reproduction, in response to cues about the probable success of reproduction in the current situation. We develop a model based on this hypothesis and explore its behavior and evolutionary and psychological implications across a range of parameter values. We use (...) the process of model development to identify assumptions implicit in the reproductive suppression hypothesis and variables that need to be measured in order to investigate it more fully. In addition, because costs were probably associated with weight control, an important part of this analysis is the specification of situations in which the benefits of adaptive adjustment of the maturation schedule could have outweighed the costs of achieving that adjustment by slowing adolescent weight gain.

We present a quantitative model of sex allocation to investigate whether the simple “rules of thumb” suggested by Trivers and Willard (1973) would really maximize numbers of grandchildren in human populations. Using demographic data from the !Kung of southern Africa and the basic assumptions of the Trivers-Willard hypothesis, we calculate expected numbers of grandchildren based on age- and sex-specific reproductive value. Patterns of parental investment that would maximize numbers of expected grandchildren often differ from the Trivers-Willard rules. In particular, the (...) optimum parental behavior is sensitive to population dynamics, type of parental investment, and, most important, relative ages of sons and daughters. It is doubtful whether a parent blindly following the simple Trivers-Willard rules would maximize numbers of expected grandchildren, on average. In addition, we show that sex-specific infanticide will almost never achieve the goal of maximizing expected numbers of grandchildren. (shrink)

Previous research in North America has supported the view that male involvement in committed, romantic relationships is associated with lower testosterone (T) levels. Here, we test the prediction that undergraduate men involved in committed, romantic relationships (paired) will have lower T levels than men not involved in such relationships (unpaired). Further, we also test whether these differences are more apparent in samples collected later, rather than earlier, in the day. For this study, 107 undergraduate men filled out a questionnaire and (...) collected one saliva sample (from which a subject’s T level was measured) at various times across the day. As in previous studies, men involved in committed, romantic relationships had lower salivary T levels, though only during later times of the day. Furthermore, additional analysis of the variation among unpaired subjects indicated that men without prior relationship experience had lower T levels than experienced men. Finally, while paired men as a group had lower T levels than unpaired men, those men at the earliest stage (less than six months) of a current relationship had higher T levels than unpaired men as well as men in longer-term relationships. These results suggest that variation in male testosterone levels may reflect differential behavioral allocation to mating effort. (shrink)

How is language acquired when infants are exposed to multiple language input from birth and when adults are required to learn a second language after early childhood? How do adult bilinguals comprehend and produce words and sentences when their two languages are potentially always active and in competition with one another? What are the neural mechanisms that underlie proficient bilingualism? What are the general consequences of bilingualism for cognition and for language and thought? This handbook will be essential reading for (...) cognitive psychologists, linguists, applied linguists, and educators who wish to better understand the cognitive basis of bilingualism and the logic of experimental and formal approaches to language science.

Language’s intentional nature has been highlighted as a crucial feature distinguishing it from other communication systems. Specifically, language is often thought to depend on highly structured intentional action and mutual mindreading by a communicator and recipient. Whilst similar abilities in animals can shed light on the evolution of intentionality, they remain challenging to detect unambiguously. We revisit animal intentional communication and suggest that progress in identifying analogous capacities has been complicated by (i) the assumption that intentional (that is, voluntary) production (...) of communicative acts requires mental-state attribution, and (ii) variation in approaches investigating communication across sensory modalities. To move forward, we argue that a framework fusing research across modalities and species is required. We structure intentional communication into a series of requirements, each of which can be operationalised, investigated empirically, and must be met for purposive, intentionally communicative acts to be demonstrated. Our unified approach helps elucidate the distribution of animal intentional communication and subsequently serves to clarify what is meant by attributions of intentional communication in animals and humans.

In this comprehensive collection of essays, most of which appear for the first time, eminent scholars from many disciplines—philosophy, economics, sociology, political science, demography, theology, history, and social psychology—examine the causes, nature, and consequences of present-day consumption patterns in the United States and throughout the world.

Suicidal Thoughts is a compilation of some of the most moving and insightful writing accomplished on the topic of suicide. It presents the thoughts and experiences of fifteen writers who have contemplated suicide-some on a professional level, others on a personal level, and a few, both personally and professionally. Through this collection, the reader is able to bear witness to the struggle between life and death and to the devastating aftermath of suicide. Suicidal Thoughts provides readers with a better understanding (...) of the reasons why some individuals give serious consideration to killing themselves. (shrink)

In this paper I use philosophical accounts on the relationship between trust and knowledge in science to apprehend this relationship on the Web. I argue that trust and knowledge are fundamentally entangled in our epistemic practices. Yet despite this fundamental entanglement, we do not trust blindly. Instead we make use of knowledge to rationally place or withdraw trust. We use knowledge about the sources of epistemic content as well as general background knowledge to assess epistemic claims. Hence, although we may (...) have a default to trust, we remain and should remain epistemically vigilant; we look out and need to look out for signs of insincerity and dishonesty in our attempts to know. A fundamental requirement for such vigilance is transparency: in order to critically assess epistemic agents, content and processes, we need to be able to access and address them. On the Web, this request for transparency becomes particularly pressing if (a) trust is placed in unknown human epistemic agents and (b) if it is placed in non-human agents, such as algorithms. I give examples of the entanglement between knowledge and trust on the Web and draw conclusions about the forms of transparency needed in such systems to support epistemically vigilant behaviour, which empowers users to become responsible and accountable knowers.

Prolific research suggests identity associates with pro-environmental behaviours that are individual and/or group focused. Individual PEB is personally driven, self-reliant, and are conducted on one's own. Group focused PEB is other people-reliant and completed as part of a group. A wide range of identities have been related to PEBs. For example, a recent systematic qualitative review revealed 99 different types of identities studied in a PEB context. Most studies were correlational, few had an experimental design. However, the relationships between all (...) these identities and PEBs have so far not been tested quantitatively with meta-analytical techniques. As such, a clear overview of this field is currently lacking. Due to the diverse nature of the field, a priori hypotheses were not possible and relatively broad definitions of identity had to be used to encompass all types of identities and the diverse meanings of identity that have been included in PEB research. What prior theory did allow for was to assess the distinction between two main types of identity, namely how people label, describe, and recognise oneself individually, or as part of a group. Our overall goal was thus to assess the current state of knowledge on identities and PEBs. In 104 studies using a meta-regression following the preferred reporting items for systematic reviews and meta-analyses guidelines, our random-effects meta-analysis showed that the overall concept of identity associated with PEB with a medium Pearson's r. Furthermore, we found that individual identities associated more strongly with PEBs than group identities. The associations between individual and group identities were stronger when the identity and PEB were from the same category. Methodologically, the findings revealed that group identities and group PEBs were most strongly associated for self-reported rather than observed PEBs. Overall identity associated most strongly with group PEBs in the field rather than in the lab and in student- rather than non-student samples. We discuss the theoretical and practical implications.

It has been claimed that a sense of us is presupposed for shared intentions to be possible. Searle introduced this notion together with the notion of the sense of the other. in joint action. It argues that the sense of the other is a necessary condition for a sense of us. Whereas thisarticle distinguishes between the “sense of the other” and the “sense of us” and elaborates on their role the sense of the other is immediate and automatic, the sense (...) of us can (but need not) arise between people and can (a) develop over time, (b) depend on the situation, and (c) involves several sufficient but not necessary processes. The article relies on research on core knowledge to better understand the sense of the other. It elaborates the sense of us using insights from cognitive science and social psychology. The article shows that the sense of the other and the sense of us can contribute to our understanding of the perception of possibilities for joint action and how individuals can come to experience actions and intentions as shared, even if the participants lack common knowledge. This leads to the conclusion that people are ordinarily socially oriented rather than individually. (shrink)

Moral theorists often say such things as “But surely A ought to do such and such,” or “Plainly it is morally permissible for B to do so and so,” and do not even try to prove that those judgments are true. Moreover, they often rest weight on the supposition that those judgments are true. In particular, they often rest theories on them: they take them as data. Others object. They say that nobody is entitled to rest any weight at all (...) on judgments such as those. They say, not that the judgments are false, but that there is no reason to believe them true. They say, more generally, that there is no reason to think of any moral judgment that it is true. I will call this The No Reason Thesis. Is there reason to think The No Reason Thesis true? There are lots of arguments for it in the literature, but I want to focus on one of them in particular. I think that the one I will focus on lies behind all the others, but no matter if it does not: I suggest that if this argument fails, they all fail. (shrink)

Most of us have certain intuitions about moral rights, at least partially captured by the ideas that: (A) rights carry special weight in moral argument; (B) persons retain their rights even when they are legitimately infringed; although (C) rights undoubtedly do conflict with one another, and are sometimes overridden as well by nonrights considerations. I show that Dworkin's remarks about rights allow us to affirm (A), (B), and (C), yet those remarks are extremely vague. I then argue that Feinberg's more (...) comprehensive and precise theory, designed to do justice to all three theses, cannot assure us of (A), that rights are not merely one consideration to be weighed in the balance with heterogeneous others. I show how Feinberg accepts (C) despite being drawn toward an alternative absolutist theory of rights and commits himself to (B) through his rejection of prima facie rights. But his promising distinction between recognition and enforcement of a right, which helps give some sense to (B) despite its tension with (C), undermines the force of rights in moral argument apparently intended by (A). We thus learn that Feinberg's and Dworkin's accounts of rights are incompatible, though each is correct in important ways. Contrasting their views allows us to clarify the implications and consistency of alternative theses about rights, one step toward meeting the challenge of developing a theory which shows more adequately how respect for rights is to be combined with other intuitions about rights and their relation to other values.

This article attempts to establish and examine the context of the two remaining mythological paintings in the Macellum, the central market of Pompeii. Panels of Io and Argos and of Penelope and Odysseus grace the interior walls, and while the identification of the Penelope figure has been the subject of debate, she clearly derives from Greek prototypes of Penelope, both material and theatrical. Indeed, scholars suggest that the Io panel and perhaps the Penelope painting as well are copies of Greek (...) panel paintings created by a fourth-century B.C. artist, but it is argued here that their pairing seems to be a Roman creation and that they were part of a larger narrative program. The paintings are compositional opposites and share the narrative technique of depicting moments of quiet tension; this choice of narrative moment is one that began in the Greek world; particularly during the Hellenistic period, and was developed and enhanced by the Romans. Moreover, this interest in creating tension for the spectator, and in the relationship between viewer and image, is also demonstrated by the inclusion of a spectator figure in the Penelope painting. Although the other paintings do not survive, their subjects are known from a nineteenth-century drawing and from nineteenth-century descriptions, and these too share the same narrative technique. If the lost paintings are copies of Greek originals, then the Macellum may have served as a picture gallery for Pompeii's inhabitants. A careful reading of the Macellum paintings of Greek myths, their juxtaposition and relationship to each other, and their reception in Roman literature and society reveals that the paintings were arranged as a program, a moralizing ensemble, designed to instruct the viewer on the proper behavior of Roman matrons.

A major international consultancy firm identified ‘AI ethicist’ as an essential position for companies to successfully implement artificial intelligence (AI) at the start of 2019. It declares that AI ethicists are needed to help companies navigate the ethical and social issues raised by the use of AI. Top 5 AI hires companies need to succeed in 2019. The view that AI is beneficial but nonetheless potentially harmful to individuals and society is widely shared by the industry, academia, governments, and civil (...) society organizations. Accordingly and in order to realize its benefits while avoiding ethical pitfalls and harmful consequences, numerous initiatives have been established to a) examine the ethical, social, legal and political dimensions of AI and b) develop ethical guidelines and recommendations for design and implementation of AI.

We suggest that morbid jealousy falls on the extreme end of a jealousy continuum. Thus, many features associated with normal jealousy will be present in individuals diagnosed with morbid jealousy. We apply Boyer & Lienard's (B&L's) prediction one (P1; target article, sect. 7.1) to morbid jealousy, suggesting that fitness-related life-cycle dimensions predict sensitivity to cues, and frequency, intensity, and content of intrusive thoughts of partner infidelity.
