Ten years ago, researchers using event-related brain potentials to study language comprehension were puzzled by what looked like a Semantic Illusion: Semantically anomalous, but structurally well-formed sentences did not affect the N400 component—traditionally taken to reflect semantic integration—but instead produced a P600 effect, which is generally linked to syntactic processing. This finding led to a considerable amount of debate, and a number of complex processing models have been proposed as an explanation. What these models have in common is that they (...) postulate two or more separate processing streams, in order to reconcile the Semantic Illusion and other semantically induced P600 effects with the traditional interpretations of the N400 and the P600. Recently, however, these multi-stream models have been called into question, and a simpler single-stream model has been proposed. According to this alternative model, the N400 component reflects the retrieval of word meaning from semantic memory, and the P600 component indexes the integration of this meaning into the unfolding utterance interpretation. In the present paper, we provide support for this “Retrieval–Integration ” account by instantiating it as a neurocomputational model. This neurocomputational model is the first to successfully simulate the N400 and P600 amplitude in language comprehension, and simulations with this model provide a proof of concept of the single-stream RI account of semantically induced patterns of N400 and P600 modulations.

Evidence from numerous studies using the visual world paradigm has revealed both that spoken language can rapidly guide attention in a related visual scene and that scene information can immediately influence comprehension processes. These findings motivated the coordinated interplay account (Knoeferle & Crocker, 2006) of situated comprehension, which claims that utterance‐mediated attention crucially underlies this closely coordinated interaction of language and scene processing. We present a recurrent sigma‐pi neural network that models the rapid use of scene information, exploiting an (...) utterance‐mediated attentional mechanism that directly instantiates the CIA. The model is shown to achieve high levels of performance (both with and without scene contexts), while also exhibiting hallmark behaviors of situated comprehension, such as incremental processing, anticipation of appropriate role fillers, as well as the immediate use, and priority, of depicted event information through the coordinated use of utterance‐mediated attention to the scene.

Experimental research shows that human sentence processing uses information from different levels of linguistic analysis, for example, lexical and syntactic preferences as well as semantic plausibility. Existing computational models of human sentence processing, however, have focused primarily on lexico‐syntactic factors. Those models that do account for semantic plausibility effects lack a general model of human plausibility intuitions at the sentence level. Within a probabilistic framework, we propose a wide‐coverage model that both assigns thematic roles to verb–argument pairs and determines a (...) preferred interpretation by evaluating the plausibility of the resulting (verb, role, argument) triples. The model is trained on a corpus of role‐annotated language data. We also present a transparent integration of the semantic model with an incremental probabilistic parser. We demonstrate that both the semantic plausibility model and the combined syntax/semantics model predict judgment and reading time data from the experimental literature. (shrink)

A variety of mechanisms contribute to word learning. Learners can track co-occurring words and referents across situations in a bottom-up manner. Equally, they can exploit sentential contexts, relying on top–down information such as verb–argument relations and world knowledge, offering immediate constraints on meaning. When combined, CSWL and SLCL potentially modulate each other's influence, revealing how word learners deal with multiple mechanisms simultaneously: Do they use all mechanisms? Prefer one? Is their strategy context dependent? Three experiments conducted with adult learners reveal (...) that learners prioritize SLCL over CSWL. CSWL is applied in addition to SLCL only if SLCL is not perfectly disambiguating, thereby complementing or competing with it. These studies demonstrate the importance of investigating word-learning mechanisms simultaneously, revealing important characteristics of their interaction in more naturalistic learning environments.

Expectation-based theories of language comprehension, in particular Surprisal Theory, go a long way in accounting for the behavioral correlates of word-by-word processing difficulty, such as reading times. An open question, however, is in which component of the Event-Related brain Potential signal Surprisal is reflected, and how these electrophysiological correlates relate to behavioral processing indices. Here, we address this question by instantiating an explicit neurocomputational model of incremental, word-by-word language comprehension that produces estimates of the N400 and the P600—the two most (...) salient ERP components for language processing—as well as estimates of “comprehension-centric” Surprisal for each word in a sentence. We derive model predictions for a recent experimental design that directly investigates “world-knowledge”-induced Surprisal. By relating these predictions to both empirical electrophysiological and behavioral results, we establish a close link between Surprisal, as indexed by reading times, and the P600 component of the ERP signal. The resultant model thus offers an integrated neurobehavioral account of processing difficulty in language comprehension. (shrink)

Beyond the observation that both speakers and listeners rapidly inspect the visual targets of referring expressions, it has been argued that such gaze may constitute part of the communicative signal. In this study, we investigate whether a speaker may, in principle, exploit listener gaze to improve communicative success. In the context of a virtual environment where listeners follow computer-generated instructions, we provide two kinds of support for this claim. First, we show that listener gaze provides a reliable real-time index of (...) understanding even in dynamic and complex environments, and on a per-utterance basis. Second, we show that a language generation system that uses listener gaze to provide rapid feedback improves overall task performance in comparison with two systems that do not use gaze. Aside from demonstrating the utility of listener gaze in situated communication, our findings open the door to new methods for developing and evaluating multi-modal models of situated interaction.

In referential communication, Grice's Maxim of Quantity is thought to imply that utterances conveying unnecessary information should incur comprehension difficulties. There is, however, considerable evidence that speakers frequently encode redundant information in their referring expressions, raising the question as to whether such overspecifications hinder listeners’ processing. Evidence from previous work is inconclusive, and mostly comes from offline studies. In this article, we present two event‐related potential (ERP) experiments, investigating the real‐time comprehension of referring expressions that contain redundant adjectives in complex (...) visual contexts. Our findings provide support for both Gricean and bounded‐rational accounts. We argue that these seemingly incompatible results can be reconciled if common ground is taken into account. We propose a bounded‐rational account of overspecification, according to which even redundant words can be beneficial to comprehension to the extent that they facilitate the reduction of listeners’ uncertainty regarding the target referent.

Spiritual/religious coping has proven to be a fertile ground for investigating health-related spirituality in action. Ken Pargament and his colleagues have successfully demonstrated that spiritual/religious coping differs significantly from previously identified coping strategies. While much has been accomplished to date, there are undeveloped theoretical and methodological avenues that appear to provide important promise for understanding the complexities of this critical domain of coping. Some scholars have failed to conceptualize and research spiritual/religious coping as a contextual, temporally bounded process. This paper (...) explores the theoretical and methodological advantages of adopting a contextually embedded, process-oriented epistemology—contextual action theory. We propose that doing so will not only address some of the inadequacies of the extant literature but also aid researchers in exploring novel dimensions of spiritual/religious coping. From a contextual action-theory perspective, spiritual/religious coping is viewed as intentional, goal-directed behaviour that is embedded in a social and relational context. This teleonomic reconceptualization enables researchers to understand the constitution and development of intentions involved in the process of spiritual/religious coping over time. Further, a contextual action theory perspective transcends the narrow, individualistic lens of coping and explores joint and collective coping processes that emerge as people draw upon spiritual/religious practices to cope with distress. Thus, spiritual/religious coping is embedded in social and relational context and as part of personal, intentional goal-directed processes over time. The novel contributions of a contextual theoretical perspective to spiritual/religious coping research and theory are illustrated through a case example. (shrink)

The comparison of growth, whether it is between different strains or under different growth conditions, is a classic microbiological technique that can provide genetic, epigenetic, cell biological, and chemical biological information depending on how the assay is used. When employing solid growth media, this technique is limited by being largely qualitative and low throughput. Collecting data in the form of growth curves, especially automated data collection in multi‐well plates, circumvents these issues. However, the growth curves themselves are subject to stochastic (...) variation in several variables, most notably the length of the lag phase, the doubling rate, and the maximum expansion of the culture. Thus, growth curves are indicative of trends but cannot always be conveniently averaged and statistically compared. Here, we summarize a simple method to compile growth curve data into a quantitative format that is amenable to statistical comparisons and easy to graph and display. (shrink)

Critics of synergism often complain that the view entails Pelagianism, and so, critics think, monergism looks like the only live option. Critics of monergism often claim that the view entails that the blame for human sin ultimately traces to God. Recently, several philosophers have attempted to chart a middle path by offering soteriological accounts which are monergistic but maintain the resistibility of God’s grace. In this paper, we present a challenge to such accounts of the resistibility of grace, namely that (...) they imply that human beings are praiseworthy for omitting to resist God’s grace. Even if such views escape Pelagianism as it is typically defined, they fail to avoid the worry at the heart of prominent criticisms of Pelagianism concerning the praise for a human being’s salvation. At the end of the paper, we suggest three possible solutions to this problem. (shrink)

This book is a collection of edited interviews from The Free Will Show-a podcast that provides a beginner-friendly introduction to free will while also highlighting recent developments on the topic. The book includes original material as well, including an introduction to the interviews and an afterward with reflections on the podcast by the authors (who are cohosts of The Free Will Show). The book also includes a bibliography and suggestions for further reading after each interview and a glossary of terms (...) at the end of the book. The book will serve well either as a textbook or as an accessible entry-point to the free will debate, whether for an interested non-specialist or a philosopher who works in another area. The first half of this book introduces the main issues and arguments in philosophical debates about free will, including various apparent threats to free will (fatalism, foreknowledge, and determinism), the Consequence Argument, and the problem of luck, among others. The second half of this book introduces the main positions in the debate about free will and determinism, including several varieties of libertarianism and compatibilism, a version of free will skepticism, and some other positions that do not fit neatly into these categories.

This article stages a new encounter between rhetoric and the philosophy of Karl Marx. We argue that the configuration of two major tropes in Marx’s 1852 pamphlet The Eighteenth Brumaire of Louis Bonaparte renders explicit the operative but implicit logics of Marxian historical materialism. Our reading therefore makes available a novel and untimely dimension of Marx’s conceptual labor where we least expect to find it: in a text that has been largely, but not exclusively, understood as a history of counterrevolution (...) that was meant to intervene within its own context in particular ways. While we do not wish to lose sight of that context, our aim is to demonstrate that The Eighteenth Brumaire is suggestive of the.. (shrink)

Conspiracy theories (CTs) are widespread ways by which people make sense of unsettling or disturbing cultural events. Belief in CTs is often connected to problematic consequences, such as decreased engagement with conventional political action or even political extremism, so understanding the psychological and social qualities of CTs belief is important. CTs have often been understood to be “monological”, displaying the tendency for belief in one conspiracy theory to be correlated with belief in (many) others. Explanations of monologicality invoke a nomothetical (...) or “closed” mindset whereby mutually supporting beliefs based on mistrust of official explanations are used to interpret public events as conspiracies, independent of the facts about those events (which they may ignore or deny). But research on monologicality offers little discussion of the content of monological beliefs and reasoning from the standpoint of the CT believers. This is due in part to the “access problem” (Wood & Douglas, 2015): CT believers are averse to being researched because they often distrust researchers and what they appear to represent. We used several strategies to address the access problem, and investigated the symbolic resources underlying CTs by reconstructing a conspiracy worldview - a set of beliefs held by CT believers about important dimensions of ontology, epistemology, and human agency. To do this, we analysed media documents, conducted field observation, and engaged in semi-structured interviews,. We describe six main dimensions of a conspiracy worldview: Views of the nature of reality, the self, the outgroup, the ingroup, action, and the future. We also describe a typology of five types of CT believers, which vary according to their positions on each of these dimensions. Our findings converge with prior explorations of CT beliefs but also revealed novel aspects: A sense of community among CT believers, a highly differentiated representation of the outgroup, a personal journey of conversion, variegated kinds of political action, and optimistic belief in future change. These findings are at odds with the typical image of monological CT believers as paranoid, cynical, anomic and irrational. For many, the CT worldview may rather constitute the ideological underpinning of a nascent pre-figurative social movement. (shrink)

We prove that in a locally finite variety that has definable principal congruences , solvable congruences are nilpotent, and strongly solvable congruences are strongly abelian. As a corollary of the arguments we obtain that in a congruence modular variety with DPC, every solvable algebra can be decomposed as a direct product of nilpotent algebras of prime power size.

Recent work has defended “Euclidean” theories of set size, in which Cantor’s Principle (two sets have equally many elements if and only if there is a one-to-one correspondence between them) is abandoned in favor of the Part-Whole Principle (if A is a proper subset of B then A is smaller than B). It has also been suggested that Gödel’s argument for the unique correctness of Cantor’s Principle is inadequate. Here we see from simple examples, not that Euclidean theories of set (...) size are wrong, but that they must be either very weak and narrow or largely arbitrary and misleading. (shrink)

This paper examines one of the historical antecedents of Big Data, the social physics movement. Its origins are in the scientific revolution of the 17th century in Western Europe. But it is not named as such until the middle of the 19th century, and not formally institutionalized until another hundred years later when it is associated with work by George Zipf and John Stewart. Social physics is marked by the belief that large-scale statistical measurement of social variables reveals underlying relational (...) patterns that can be explained by theories and laws found in natural science, and physics in particular. This larger epistemological position is known as monism, the idea that there is only one set of principles that applies to the explanation of both natural and social worlds. Social physics entered geography through the work of the mid-20th-century geographer William Warntz, who developed his own spatial version called “macrogeography.” It involved the computation of large data sets, made ever easier with the contemporaneous development of the computer, joined with the gravitational potential model. Our argument is that Warntz's concerns with numeracy, large data sets, machine-based computing power, relatively simple mathematical formulas drawn from natural science, and an isomorphism between natural and social worlds became grounds on which Big Data later staked its claim to knowledge; it is a past that has not yet passed.

A probability distribution is regular if it does not assign probability zero to any possible event. While some hold that probabilities should always be regular, three counter-arguments have been posed based on examples where, if regularity holds, then perfectly similar events must have different probabilities. Howson and Benci et al. have raised technical objections to these symmetry arguments, but we see here that their objections fail. Howson says that Williamson’s “isomorphic” events are not in fact isomorphic, but Howson is speaking (...) of set-theoretic representations of events in a probability model. While those sets are not isomorphic, Williamson’s physical events are, in the relevant sense. Benci et al. claim that all three arguments rest on a conflation of different models, but they do not. They are founded on the premise that similar events should have the same probability in the same model, or in one case, on the assumption that a single rotation-invariant distribution is possible. Having failed to refute the symmetry arguments on such technical grounds, one could deny their implicit premises, which is a heavy cost, or adopt varying degrees of instrumentalism or pluralism about regularity, but that would not serve the project of accurately modelling chances.

The privation account of moral evil holds that the badness of morally bad acts consists not in the positive act itself or in any positive feature of the act but rather in the act’s lack of conformity to the moral standard. Traditionally recognized for its theological usefulness, the account has been the target of at least five recent objections. In this paper I offer a positive philosophical argument for the account and then show that the objections fail.

Recent research in ethics education shows a potentially problematic variation in content, curricular materials, and instruction. While ethics instruction is now widespread, studies have identified significant variation in both the goals and methods of ethics education, leaving researchers to conclude that many approaches may be inappropriately paired with goals that are unachievable. This paper speaks to these concerns by demonstrating the importance of aligning classroom-based assessments to clear ethical learning objectives in order to help students and instructors track their progress (...) toward meeting those objectives. Two studies at two different universities demonstrate the usefulness of classroom-based, formative assessments for improving the quality of students’ case responses in computational modeling and research ethics.

Counterfactual thinking involves imagining hypothetical alternatives to reality. Philosopher David Lewis argued that people estimate the subjective plausibility that a counterfactual event might have occurred by comparing an imagined possible world in which the counterfactual statement is true against the current, actual world in which the counterfactual statement is false. Accordingly, counterfactuals considered to be true in possible worlds comparatively more similar to ours are judged as more plausible than counterfactuals deemed true in possible worlds comparatively less similar. Although Lewis (...) did not originally develop his notion of comparative similarity to be investigated as a psychological construct, this study builds upon his idea to empirically investigate comparative similarity as a possible psychological strategy for evaluating the perceived plausibility of counterfactual events. More specifically, we evaluate judgments of comparative similarity between episodic memories and episodic counterfactual events as a factor influencing people's judgments of plausibility in counterfactual simulations, and we also compare it against other factors thought to influence judgments of counterfactual plausibility, such as ease of simulation and prior simulation. Our results suggest that the greater the perceived similarity between the original memory and the episodic counterfactual event, the greater the perceived plausibility that the counterfactual event might have occurred. While similarity between actual and counterfactual events, ease of imagining, and prior simulation of the counterfactual event were all significantly related to counterfactual plausibility, comparative similarity best captured the variance in ratings of counterfactual plausibility. Implications for existing theories on the determinants of counterfactual plausibility are discussed. (shrink)

At the same time that social justice concerns are on the rise on college campuses, empathy levels among US college students are falling. Social injustice resulting from organizational decisions and actions causes profound and unnecessary human suffering, and research to understand antecedents to these decisions and actions lacks attention. Empathy represents a potential tool and critical skill for organizational decision-makers, with empirical evidence linking empathy to moral recognition of ethical situations and greater breadth of understanding of stakeholder impact and improved (...) financial success. This study explores the potential relationship between empathy and social justice, using a multifaceted operationalization of social justice, which includes management actions and social sympathies. Results broadly support the positive empathy and social justice relationship and suggest higher education interventions to develop empathy in college business students. (shrink)

What are the effects of word-by-word predictability on sentence processing times during the natural reading of a text? Although information complexity metrics such as surprisal and entropy reduction have been useful in addressing this question, these metrics tend to be estimated using computational language models, which require some degree of commitment to a particular theory of language processing. Taking a different approach, this study implemented a large-scale cumulative cloze task to collect word-by-word predictability data for 40 passages and compute surprisal (...) and entropy reduction values in a theory-neutral manner. A separate group of participants read the same texts while their eye movements were recorded. Results showed that increases in surprisal and entropy reduction were both associated with increases in reading times. Furthermore, these effects did not depend on the global difficulty of the text. The findings suggest that surprisal and entropy reduction independently contribute to variation in reading times, as these metrics seem to capture different aspects of lexical predictability.

Are all God’s activities identical to God? If not, which are identical to God and which not? Although it is seldom noticed, the texts of Aquinas (at least on the surface) suggest conflicting answers to these questions, giving rise to a diversity of opinion among interpreters of Aquinas. In this paper, we draw attention to this conflict and offer what we believe to be the strongest textual and speculative support for and against each of the main answers to these questions.
