Understanding communicative intentions and semiotic vehicles by children and chimpanzees

Developmental and comparative studies of the ability to understand communicative intentions using object-choice tasks raise questions concerning the semiotic properties of the communicative signals, and the roles of rearing histories, language and familiarity. We adapted a study by Tomasello, Call, and Gluckman (1997), in which a “helper” indicated the location of a hidden reward to children of three ages (18, 24, and 30 months) and to four chimpanzees, by means of one of four cues: Pointing, Marker, Picture and Replica. For the chimpanzees, we controlled for familiarity by using two helpers, one unfamiliar and one highly familiar. Even 18-months performed well on Pointing and Marker, while only the oldest group clearly succeeded with Picture and Replica. Performance did not correlate with scores for the Swedish Early Communicative Development Inventory (SECDI). While there were no positive results for the chimpanzees on the group level, and no effect of familiarity, two chimpanzees succeeded on Pointing and Marker. Results support proposals of a species difference in understanding communicative intentions, but also highlight the need to distinguish these from the complexity of semiotic vehicles and to consider both factors.     

The Philosophy of Interdisciplinarity: Sustainability Science and Problem-Feeding

Traditionally, interdisciplinarity has been taken to require conceptual or theoretical integration. However, in the emerging field of sustainability science this kind of integration is often lacking. Indeed sometimes it is regarded as an obstacle to interdisciplinarity. Drawing on examples from sustainability science, we show that problem-feeding, i.e. the transfer of problems, is a common and fruitful-looking way of connecting disparate disciplines and establishing interdisciplinarity. We identify two species of problem-feeding: unilateral and bilateral. Which of these is at issue depends on whether solutions to the problem are fed back to the discipline in which the problem originated. We suggest that there is an interesting difference between the problem-feeding approach to interdisciplinarity and the traditional integrative perspective suggested by among others Erich Jantsch and his colleagues. The interdisciplinarity resulting from problem-feeding between researchers can be local and temporary and does not require collaboration between proximate disciplines. By contrast, to make good sense of traditional integrative interdisciplinarity we must arguably associate it with a longer-term, global form of close, interdisciplinary collaboration.     

Production of recrystallized nano-grains in a fine-grained Cu–Zn alloy

A fine-grained Cu–30%Zn alloy sheet was rolled at 77 K to induce ultrafine mechanical twins. Subsequent annealing of the rolled alloy at temperatures up to 543 K led to the uniform appearance of recrystallized ultrafine grains (UFGs), which contained numerous annealing twins. Average grain sizes of 150 ～ 300 nm were produced in this way. The formation of such UFGs during annealing is attributed to the high nucleus density associated with the fine initial grain size as well as to the high densities of mechanical twins and dislocations produced by cryorolling. The high driving force for recrystallization enabled the use of relatively low annealing temperatures, which limited the subsequent grain growth.     

The role of practice and habituation in Socrates’ theory of ethical development

ABSTRACT

The goal of this paper is to challenge the standard view that Socrates of the early Platonic dialogues is an intellectualist with respect to virtue. Through a detailed analysis of the educational theory laid out in the early dialogues, it will be argued that Socrates believes that the best way to cultivate virtues in his interlocutors is not to convince them of ethical truths by way of reason and argument alone, but to encourage them to participate in the practice of virtue. Habit and practice are essential to the cultivation of virtue because they mould the desires and dispositions of the agent and promote a kind of knowledge that cannot be achieved discursively – craft-knowledge. Only when agents have achieved craft-knowledge can they be counted on to act virtuously on every occasion; and craft-knowledge can only be achieved by way of practice and habituation.     

The Attitudinal Entropy (AE) Framework as a General Theory of Individual Attitudes

Abstract

This article introduces the Attitudinal Entropy (AE) framework, which builds on the Causal Attitude Network model that conceptualizes attitudes as Ising networks. The AE framework rests on three propositions. First, attitude inconsistency and instability are two related indications of attitudinal entropy, a measure of randomness derived from thermodynamics. Second, energy of attitude configurations serves as a local processing strategy to reduce the global entropy of attitude networks. Third, directing attention to and thinking about attitude objects reduces attitudinal entropy. We first discuss several determinants of attitudinal entropy reduction and show that several findings in the attitude literature, such as the mere thought effect on attitude polarization and the effects of heuristic versus systematic processing of arguments, follow from the AE framework. Second, we discuss the AE framework’s implications for ambivalence and cognitive dissonance.     

Prodigal Sons: Dual Abrahamic Categorization Mediates the Detrimental Effects of Religious Fundamentalism on Christian–Muslim Relations

Religious fundamentalism is associated with Christian–Islamic conflicts globally, but the psychological reasons remain unexplored. Here, we show that fundamentalism is detrimental to interreligious relations because it makes Christians and Muslims alike reject common theological grounds and Abrahamic origins. Specifically, Study 1 demonstrated that such dual Abrahamic categories mediated the negative effects of fundamentalism on real monetary donations to outgroup children desperately in need (i.e., Save the Children Syria) among Christians but not Atheists. Of importance, this was the case only to the degree that Syrian children were perceived as Muslims and, hence, as part of an Abrahamic outgroup. Using a double-randomized experimental design, Study 2 demonstrated the causal effects of religious fundamentalism on Abrahamic categorization and of Abrahamic categorization on mutual resource distribution bias among Muslims and Christians. Together, these studies suggest that religious fundamentalism fuels interreligious conflicts because it crucially impacts basic categorization processes, with subsequent negative effects on intergroup relations.     

Sexism,rape myths and feminist identification explain gender differences in attitudes toward the #metoo social media campaign in two countries

ABSTRACT

On October 15, 2017, actress Alyssa Milano popularized the #metoo campaign, which sought to expose the prevalence of sexual harassment and assault in public domains by encouraging victims to share their experiences on social media using the hashtag metoo. The online campaign rapidly grew to a global phenomenon, which was generally well supported. However, some criticized the campaign online as a battle of the sexes, which pits men against women. Our cross-cultural research investigated whether gender differences in attitudes and feelings toward #metoo are due to underlying differences in ideologies and experiences that only partly overlap with gender. We surveyed respondents in the United States, where the campaign began, and in Norway, a highly gender-egalitarian country. In both countries, men expressed less positivity toward #metoo than women and perceived it as substantially more harmful and less beneficial. These gender differences were largely accounted for by men being higher than women in hostile sexism, higher in rape myth acceptance, and lower in feminist identification. The results, hence, suggest that gender differences in attitudes to social media campaigns such as #metoo might be best characterized as dimensional ideological differences rather than fundamental group differences.     

Awareness of one's body as subject and object

Abstract

This paper rejects Hume's famous claim that we never perceive our selves, by arguing that, under conditions specified, our perception of our bodies is perception of our selves. It takes as its point of departure Quassim Cassam's defence of a position to a similar effect but puts a different interpretation on the distinction between perceiving the body as an object, having spatial attributes, and perceiving it as a self or subject of experiences.
