This paper contrasts two influential theoretical accounts of language change and evolution – Iterated Learning and Social Coordination. The contrast is based on an experiment that compares drawings produced with Garrod et al’s ‘pictionary’ task with those produced in an Iterated Learning version of the same task. The main finding is that Iterated Learning does not lead to the systematic simplification and increased symbolicity of graphical signs produced in the standard interactive version of the task. A second finding is that (...) Iterated Learning leads to less conceptual and structural alignment between participants than observed for those in the interactive condition. The paper concludes with a comparison of the two accounts in relation to how each promotes signs that are effi cient, systematic and learnable. (shrink)

Recent research indicates that interpersonal communication is noisy, and that people exhibit considerable insensitivity to problems in communication. Using a dyadic referential communication task, the goal of which is accurate information transfer, this study examined the extent to which interlocutors are sensitive to problems in communication and use other‐initiated repairs (OIRs) to address them. Participants were randomly assigned to dyads (N = 88 participants, or 44 dyads) and tried to communicate a series of recurring abstract geometric shapes to a partner (...) across a text–chat interface. Participants alternated between directing (describing shapes) and matching (interpreting shape descriptions) roles across 72 trials of the task. Replicating prior research, over repeated social interactions communication success improved and the shape descriptions became increasingly efficient. In addition, confidence in having successfully communicated the different shapes increased over trials. Importantly, matchers were less confident on trials in which communication was unsuccessful, communication success was lower on trials that contained an OIR compared to those that did not contain an OIR, and OIR trials were associated with lower Director Confidence. This pattern of results demonstrates that (a) interlocutors exhibit (a degree of) sensitivity to problems in communication, (b) they appropriately use OIRs to address problems in communication, and (c) OIRs signal problems in communication.

While psychopathy research has been growing for decades, a relatively new area of research is corporate psychopathy. Corporate psychopaths are simply psychopaths working in organizational settings. They may be attracted to the financial, power, and status gains available in senior positions and can cause considerable damage within these roles from a manipulative interpersonal style to large-scale fraud. Based upon prior studies, we analyze psychopathy research pertaining to 23 moral emotions classified according to functional quality and target. Based upon our review, (...) we suggest that psychopaths are high in moral emotions associated with other-directed negative signals, low in self-directed negative signals, and low in other-directed positive signals. We found no empirical articles related to self-directed positive signals. This understanding of the specific moral emotion deficits of corporate psychopaths provides greater theoretical understanding and practical implications of knowing which individuals not to promote, though more research is needed on moral emotions that are faked for manipulative reasons.

Human cognition and behavior are dominated by symbol use. This paper examines the social learning strategies that give rise to symbolic communication. Experiment 1 contrasts an individual-level account, based on observational learning and cognitive bias, with an inter-individual account, based on social coordinative learning. Participants played a referential communication game in which they tried to communicate a range of recurring meanings to a partner by drawing, but without using their conventional language. Individual-level learning, via observation and cognitive bias, was sufficient (...) to produce signs that became increasingly effective, efficient, and shared over games. However, breaking a referential precedent eliminated these benefits. The most effective, most efficient, and most shared signs arose when participants could directly interact with their partner, indicating that social coordinative learning is important to the creation of shared symbols. Experiment 2 investigated the contribution of two distinct aspects of social interaction: behavior alignment and concurrent partner feedback. Each played a complementary role in the creation of shared symbols: Behavior alignment primarily drove communication effectiveness, and partner feedback primarily drove the efficiency of the evolved signs. In conclusion, inter-individual social coordinative learning is important to the evolution of effective, efficient, and shared symbols. (shrink)

What should knowledge first theorists say about the value of knowledge? In this paper I approach this issue by arguing for a single ‘modest knowledge first claim’ about the value of knowledge. This is that the special value of knowledge isn’t merely instrumental value relative to true belief. I show that MKF is inconsistent with the version of the Platonic stability theory that Williamson defends in Knowledge and its Limits. I then argue in favour of MKF by arguing that Williamson’s (...) stability theory fails for reasons that plausibly generalise to any theory of the value of knowledge that is inconsistent with MKF. Crucial to this argument is a putative adequacy condition on philosophical theories of the value of knowledge: that, in order to fully explain the special value of knowledge, a theory must identify respects in which knowledge is more valuable than true belief that give enquirers adequate reason for preferring knowledge to true belief. I conclude by suggesting that this adequacy condition is the source of a more general dilemma for proponents of philosophical theories of the value of knowledge. (shrink)

The distribution of cultural variants in a population is shaped by both neutral evolutionary dynamics and by selection pressures. The temporal dynamics of social network connectivity, that is, the order in which individuals in a population interact with each other, has been largely unexplored. In this paper, we investigate how, in a fully connected social network, connectivity dynamics, alone and in interaction with different cognitive biases, affect the evolution of cultural variants. Using agent‐based computer simulations, we manipulate population connectivity dynamics (...) (early, mid, and late full‐population connectivity); content bias, or a preference for high‐quality variants; coordination bias, or whether agents tend to use self‐produced variants (egocentric bias), or to switch to variants observed in others (allocentric bias); and memory size, or the number of items that agents can store in their memory. We show that connectivity dynamics affect the time‐course of variant spread, with lower connectivity slowing down convergence of the population onto a single cultural variant. We also show that, compared to a neutral evolutionary model, content bias accelerates convergence and amplifies the effects of connectivity dynamics, while larger memory size and coordination bias, especially egocentric bias, slow down convergence. Furthermore, connectivity dynamics affect the frequency of high‐quality variants (adaptiveness), with late connectivity populations showing bursts of rapid change in adaptiveness followed by periods of relatively slower change, and early connectivity populations following a single‐peak evolutionary dynamic. We evaluate our simulations against existing data collected from previous experiments and show how our model reproduces the empirical patterns of convergence. (shrink)

In this paper I challenge the orthodox view of the significance of Platonic value problems. According to this view, such problems are among the central questions of epistemology, and answering them is essential for justifying the status of epistemology as a major branch of philosophical enquiry. I challenge this view by identifying an assumption on which Platonic value problems are based – the value assumption – and considering how this assumption might be resisted. After articulating a line of thought that (...) supports the assumption, I highlight one way of undermining it, which is to deny that we desire knowledge and not just true belief because we prefer knowledge to true belief. I then consider an attempt to undermine the value assumption in this way, inspired by Bernard Williams. I contend that Williams's argument fails, but also that seeing why it fails is instructive for future attempts to resist the value assumption. (shrink)

The use of sound to systematically communicate data has been with us for a long time, and has received considerable research, albeit in a broad range of distinct fields of inquiry. Sonification is uniquely capable of conveying series and patterns, trends and outliers…and effortlessly carries affect and emotion related to those data. And sound-either by itself or in conjunction with visual, tactile, or even olfactory representations-can make data exploration more compelling and more accessible to a broader range of individuals. Nevertheless, (...) sonification and auditory displays still occupy only a sliver of popular mindshare: most people have never thought about using non-speech sound in this manner, even though they are certainly very familiar with other intentional uses of sound to convey status, notifications, and warnings. This article provides a brief history of sonification, introduces terms, quickly surveys a range of examples, and discusses the past, present, and as-yet unrealized future promise of using sound to expand the way we can communicate about data, broaden the use of auditory displays in society, and make science more engaging and more accessible.

Research indicates that academic growth and student behavior are inextricably linked. Schools that systematically address both academic and social/emotional learning (SEL) have shown increased student achievement when compared to schools that do not address both factors ( Elliott, Huai & Roach, 2007 ; Hawken, Vincent & Schumann, 2008 ). Even with this understanding, outcomes for students with emotional and behavioral disabilities (EBD) continue to be of concern ( Bradley, Doolittle & Bartolotta, 2008 ). This study explores the effectiveness of integrating (...) SEL and social studies learning in the self-contained special education classroom for students with EBD using Storypath, an inquiry-based social studies curriculum. We hypothesized that the systematic integration of SEL opportunities into meaningful, well-planned and engaging academic instruction could provide students with an opportunity to authentically learn and practice key social and academic skills. Quantitative findings via an online survey and qualitative findings via interviews and observations indicate that students with EBD can successfully engage in less structured and more cognitively challenging academic activities and use SEL skills effectively in the context of these lessons.

None is so poor that he need sit on a pumpkin.Henry Thoreau, Walden.

Cultural evolutionary theory has identified a range of cognitive biases that guide human social learning. Naturalistic and experimental studies indicate transmission biases favoring negative and positive information. To address these conflicting findings, the present study takes a socially situated view of information transmission, which predicts that bias expression will depend on the social context. We report a large‐scale experiment (N = 425) that manipulated the social context and examined its effect on the transmission of the positive and negative information contained (...) in a narrative text. In each social context, information was progressively lost as it was transmitted from person to person, but negative information survived better than positive information, supporting a negative transmission bias. Importantly, the negative transmission bias was moderated by the social context: Higher social connectivity weakened the bias to transmit negative information, supporting a socially situated account of information transmission. Our findings indicate that our evolved cognitive preferences can be moderated by our social goals. (shrink)

Provides an insight into the ever changing boundaries between science and philosophy.

In Ethics and the Autonomy of Philosophy, Bernard Walker sets out with two objectives. First, Walker argues that ethics is autonomous as a discipline. Oftentimes ethics books, from a Christian perspective, lean toward grounding ethics in theology or in biblical proof texting. Walker departs from this tradition. Ethics grounded in theology entails a limited scope for those doing ethics in that the Christian God must be assumed for both Christian and non-Christian when at the table of ethical dialogue. For the (...) non-Christian, this loads the dice and shuts down ethical consensus and dialogue, if not ethical truth. With that said, this book does not depart from Christian ethical views on such issues as the sanctity of life, antiracism, the death penalty, the objectivity of ethics, and the importance of integrating faith into ethics; however, Walker does so from a common denominator of philosophy rather than theology. Second, Walker ventures into the streets and engages the man/woman on the streets approach to ethics and ethical decision-making. He points out the shortcomings of the ubiquitous views of the man/woman on the streets, viz., cultural relativism, skepticism, and the attitude that ethics is merely a matter of personal choice.

How well the Sustainable Development Goals (SDGs) are achieved will greatly influence the lives of today’s children and decisively shape the rest of the 21st century. Yet, children were largely excluded from opportunities to influence the selection of SDGs and their associated targets and indicators, and major barriers to meaningful child engagement remain. However, child-focused agencies have found that when children are intentionally enabled to participate in seeking accountability, they can influence their families, communities and governments to value their contributions (...) and increase their well-being. In furthering its strategy of building brighter futures for children, World Vision implements Citizen Voice and Action (CV&A), a strategic social accountability approach, into communities where children are severely impoverished. Drawing on empirical evidence from children’s CV&A experiences, this paper enquires into the circumstances under which children are empowered to seek accountability for SDGs. This article identifies shared processes which they and others use to strengthen children’s participation in seeking social justice through social accountability. This paper argues that children possess under-recognised research capabilities to think and reflect systemically, critique, understand, and pursue socially just and equitable outcomes conducive to the SDGs, which under the right circumstances, can influence practices, policies, laws and systems.

This thesis is about toleration as a modality of citizenship for pluralistic societies. Its central argument is that the current dissatisfaction with "mere" toleration which we find so broadly represented in our public and scholarly cultures is based on an underestimation of the capacities and attitudes that toleration entails. The liberal recasting of toleration, sophisticated and indeed invaluable though it is abets this devaluation by focusing too exclusively on public justification and on the Lockean stream of the tradition from which (...) we draw. ;The present thesis begins by tracing some of the difficulties facing the Rawlsian and Habermasian projects if we accept a vivid picture of the pluralisms amidst which we live. It then sketches the central features of a complementary tradition of toleration as it flows to us through the works of Montaigne, William James, Mikhail Bakhtin and others. An attempt is made to show where the resources drawn from this tradition might fit in to a theory of citizenship given reasonable Rawlsian qualms about "thick" public conceptions and given the fissiparous nature of a civil society like ours. The thesis ends with a pair of empirically oriented chapters which show ways in which we could conceive a praxis of toleration which might respond to the issues raised in the earlier sections of the work.

Utilizing memory, orality and performance this article posits a model of how the miracle tradition of Jesus may have been transmitted. What was spoken of and remembered, specifically, about Jesus’ miracles provided faith and transformation in the discipleship process both during the life of Jesus and after. Jesus extended his ministry to The Twelve and others through calling them to participate in his Kingdom mission through imitating him in word and deed, particularly miracle working.

Given the immense mobilizing power possessed by the rhetoric of nationalism, as well as the many resources which can be tapped by groups which successfully establish national claims, it is not surprising that we have recently seen such a resurgence in nationalist discourse. One of the things which may surprise us, however, is the growing breadth in thetypesof groups which now launch such claims. No longer is the discourse of nationalism limited to use by ethnic groups and territorial populations. Recently (...) it has come to be deployed by groups which we would normally tend to look upon as social movements. There has been a growing realization of the way in which constituencies such as Blacks, gays and lesbians, Chicano/as, and so on, make up distinct peoples, with cultures, public institutions, dialects, tastes, and social practices that set them off from the people or peoples around them.
