Foundations of Cooperation in Young Children

Observations and experiments show that human adults preferentially share resources with close relations, with people who have shared with them (reciprocity), and with people who have shared with others (indirect reciprocity). These tendencies are consistent with evolutionary theory but could also reflect the shaping effects of experience or instruction in complex, cooperative and competitive societies. Here we report evidence for these three tendencies in 3.5 year old children, despite their limited experience with complex cooperative networks. Three pillars of mature cooperative behavior therefore appear to have roots extending deep into human development.Psycholog

Debunking Intellectual Property Myths: Cross Cultural Experiments on Perceptions of Property

For decades, the prevailing view in the United States and many Western countries has been that China does not appropriately respect intellectual property rights. These beliefs lie at the heart of President Donald Trump’s current trade war with China. Despite substantial geopolitical debate over differences between American an d Chinese attitudes towards intellectual property rights, and despite the critical effects that such attitudes have on international economic markets and the function of intellectual property systems, empirical evidence of these attitudes is largely lacking. This Article presents original experimental survey research that explores cross cross-cultural differences between American and Chinese attitudes towards intellectual property rights, personal property rights, and real property rights. The results of the studies are somewhat counterintuitive. First, Chinese participants are found to have more consistent preferences towards different types of property rights than Americans. In a series of vignettes designed to test attitudes towards patented subject matter, copyrighted subject matter, tangible personal property, and real property, Chinese responses were more consistent and less context driven. Second, Americans do identify a preference for stronger intellectual property rights than Chinese, but only where infringement is committed by a private party for private benefit. Where infringement is conducted for public benefit, whether by a private or a governmental entity, Chinese and Americans tend to have the same attitudes towards intellectual property rights. Third , Americans display a lower regard for intellectual property rights than for tangible property rights in most contexts, a differential that is not echoed in Chinese responses. The distinctions that Americans draw based on the use to which property is put, and between intellectual property and tangible property, is not consistent with United States law. Our experiments reveal that the ongoing debates over Chinese attitudes towards intellectual property rights miss the mark in certain regards. Chinese and American preferences for property rights are more similar than most have assumed, and the manners in which they differ are inconsistent with most proffered theories. These results provide important lessons for the future of international intellectual property rights relations, discourse, and enforcement

Intellectual Property Law’s Plagiarism Fallacy

Intellectual property law is caught in a widespread debate over whether it should serve incentive or natural rights objectives, and what the best means for achieving those ends are. This article reports a series of experiments revealing that these debates are actually orthogonal to how most users and many creators understand intellectual property law. The most common perception of intellectual property among the American public is that intellectual property law is designed to prevent plagiarism. The plagiarism fallacy in intellectual property law is not an innocuous misperception. This fallacy likely helps explain pervasive illegal infringing activity on the Internet, common dismissal of copyright warnings, and other previously puzzling behavior. The received wisdom has been that the public is ethically dismissive or indifferent towards intellectual property rights. This research reveals instead that experts have failed to comprehend what the public’s conception of intellectual property law actually is. The studies reported here uncover several additional intellectual property law findings, including that (1) the majority of the American public views intellectual property rights as too broad and too strong, (2) knowledge of intellectual property law does not affect opinions about what the law should be, and (3) there are significant demographic and cultural divides concerning attitudes towards intellectual property rights. The findings as a whole raise central questions concerning the public legitimacy of intellectual property law and, consequently, its ability to function as intended

Children's Responses to Group-Based Inequalities: Perpetuation and Rectification

The current studies investigate whether, and under what conditions, children engage in system-perpetuating and system-attenuating behaviors when allocating resources to different social groups. In three studies, we presented young children with evidence of social group inequalities and assessed whether they chose to perpetuate or rectify these inequalities. Children (aged 3.5–11.5 years) heard about two social groups (i.e., racial or novel groups) whose members received resources unequally (two cookies versus one). Participants were then given the opportunity to distribute additional resources to new members of the same groups. In Experiment 1, when children were presented with inequalities involving groups of Blacks and Whites, older children (aged 7.5–11.5 years) rejected the status quo, providing more resources to members of groups with fewer resources (White or Black), whereas younger children (aged 3.5–7.5 years) perpetuated the status quo. In Experiments 2 and 3, the inequalities involved Asians and Whites and novel groups. Children of all ages perpetuated inequality, with rectification strategies applied only by older children and only when Black targets were involved in the inequality. Equal sharing occasionally occurred in older children but was never a common response. These findings provide evidence that system-perpetuating tendencies may be predominant in children and suggest that socialization may be necessary to counter them.Psycholog

Judgements of the Lucky Across Development and Culture

For millennia human beings have believed that it is morally wrong to judge others by the fortuitous or unfortunate events that befall them or by the actions of another person. Rather, an individual’s own intended, deliberate actions should be the basis of his/her evaluation, reward and punishment. In a series of studies we investigate whether such rules guide the judgments of children. The first three studies demonstrate that children view lucky others as more likely than unlucky others to perform intentional good actions. Children similarly assess the siblings of lucky others as more likely to perform intentional good actions than the siblings of unlucky others. The next three studies demonstrate that children as young as 3 years believe that lucky people are nicer than unlucky people. The final two studies find that Japanese children also demonstrate a robust preference for the lucky and their associates. These findings are discussed in relation to Lerner’s just world theory and Piaget’s immanent justice research and in relation to the development of intergroup attitudes.Psycholog

Microfocal X-Ray Computed Tomography Post-Processing Operations for Optimizing Reconstruction Volumes of Stented Arteries During 3D Computational Fluid Dynamics Modeling

Restenosis caused by neointimal hyperplasia (NH) remains an important clinical problem after stent implantation. Restenosis varies with stent geometry, and idealized computational fluid dynamics (CFD) models have indicated that geometric properties of the implanted stent may differentially influence NH. However, 3D studies capturing the in vivo flow domain within stented vessels have not been conducted at a resolution sufficient to detect subtle alterations in vascular geometry caused by the stent and the subsequent temporal development of NH. We present the details and limitations of a series of post-processing operations used in conjunction with microfocal X-ray CT imaging and reconstruction to generate geometrically accurate flow domains within the localized region of a stent several weeks after implantation. Microfocal X-ray CT reconstruction volumes were subjected to an automated program to perform arterial thresholding, spatial orientation, and surface smoothing of stented and unstented rabbit iliac arteries several weeks after antegrade implantation. A transfer function was obtained for the current post-processing methodology containing reconstructed 16 mm stents implanted into rabbit iliac arteries for up to 21 days after implantation and resolved at circumferential and axial resolutions of 32 and 50 μm, respectively. The results indicate that the techniques presented are sufficient to resolve distributions of WSS with 80% accuracy in segments containing 16 surface perturbations over a 16 mm stented region. These methods will be used to test the hypothesis that reductions in normalized wall shear stress (WSS) and increases in the spatial disparity of WSS immediately after stent implantation may spatially correlate with the temporal development of NH within the stented region

Children Develop a Veil of Fairness

Previous research suggests that children develop an increasing concern with fairness over the course of development. Research with adults suggests that the concern with fairness has at least two distinct components: a desire to be fair but also a desire to signal to others that they are fair. We explore whether children’s developing concern with behaving fairly towards others may in part reflect a developing concern with appearing fair to others. In Experiments 1-2, most 6- to 8-year-old children behaved fairly towards others when an experimenter was aware of their choices; fewer children opted to behave fairly, however, when they could be unfair to others yet appear fair to the experimenter. In Experiment 3, we explored the development of this concern with appearing fair by using a wider age range (6- to 11-year-olds) and a different method. In this experiment, children chose how to assign a good or bad prize to themselves and another participant by either unilaterally deciding who would get each prize or by using a fair procedure – flipping a coin in private. Older children were much more likely to flip the coin than younger children, yet were just as likely as younger children to assign themselves the good prize by reporting winning the coin flip more than chance would dictate. Overall, the results of these experiments suggest that as children grow older they become increasingly concerned with appearing fair to others, which may explain some of their increased tendency to behave fairly
