Taking Parenting Public makes a compelling case that parenting has become dangerously undervalued in America today. It calls for a new investment—both personal and public—into the work of raising children and argues that we are all "stockholders" in the next generation. With a foreword by Sylvia Ann Hewlett and Cornel West, Taking Parenting Public crosses boundaries to bring together thinkers from diverse fields spanning the political spectrum. It features contributions from distinguished experts in economics, political science, public policy, child development, (...) public health, history, and the media. While recent books have focused on working mothers or absent fathers, Taking Parenting Public is the first volume to take a comprehensive look at the common struggles of parents. These essays go beyond the usual chest-beating about busy parents torn between work and family demands to suggest bold solutions. Instead of the typical call for "parent replacement"—more child care, more after school programs and more mentors—the contributors offer fresh strategies for "parent replenishment," ways to put mothers and fathers back into the lives of their children not only as economic providers, but also as emotional and moral providers.

We suggest that policies will be less popular when individuals personally have to pay for them rather than when others have to pay (i.e., a Not Out of My Bank Account or NOMBA effect). Dual process models of persuasion suggest that personally having to pay would motivate scrutiny of persuasive messages making it essential to use effective science communication tactics when using climate science to support climate change policies. A pilot experiment (N = 186) and main study (N = 758) (...) support a NOMBA effect with less policy support (Pilot study) and lower recommended fees (Main study) for a policy that would require participants, rather than another group, to pay a fee for community solar panels. Consistent with dual process models and suggesting systematic processing, only when participants would have to pay the fee, messages using strong (vs. weak) science communication tactics increased support for policies (Pilot study), increased the favorability of thoughts about the policy (Main study) and these thoughts subsequently predicted policy support (Main study). Inconsistent with propositions that information about expert sources would be a heuristic or bolster science messages, expert consensus information did not influence thoughts or policy support in any study condition. Efforts to understand climate change policy support would benefit from attending to research on dual process models of persuasion, including understanding how different types and degree of outcome relevance can alter how people process science information used to bolster support for climate change policies.

Given its non-invasive nature, there is increasing interest in the use of transcutaneous vagus nerve stimulation across basic, translational and clinical research. Contemporaneously, tVNS can be achieved by stimulating either the auricular branch or the cervical bundle of the vagus nerve, referred to as transcutaneous auricular vagus nerve stimulation and transcutaneous cervical VNS, respectively. In order to advance the field in a systematic manner, studies using these technologies need to adequately report sufficient methodological detail to enable comparison of results between (...) studies, replication of studies, as well as enhancing study participant safety. We systematically reviewed the existing tVNS literature to evaluate current reporting practices. Based on this review, and consensus among participating authors, we propose a set of minimal reporting items to guide future tVNS studies. The suggested items address specific technical aspects of the device and stimulation parameters. We also cover general recommendations including inclusion and exclusion criteria for participants, outcome parameters and the detailed reporting of side effects. Furthermore, we review strategies used to identify the optimal stimulation parameters for a given research setting and summarize ongoing developments in animal research with potential implications for the application of tVNS in humans. Finally, we discuss the potential of tVNS in future research as well as the associated challenges across several disciplines in research and clinical practice. (shrink)

Evidentialism as an account of epistemic justification is the position that a doxastic attitude, D, towards a proposition, p, is justified for an intentional agent, S, at a time, t, iff having D towards p fits S’s evidence at t, where the fittingness of an attitude on one’s evidence is typically analyzed in terms of evidential support for the propositional contents of the attitude. Evidentialism is a popular and well-defended account of justification. In this paper, I raise a problem for (...) evidentialism on the grounds that there can be epistemic circumstances in which a proposition is manifestly and nonmisleadingly supported by an agent’s total evidence, and yet believing the proposition is not justified for the agent. As I argue, in order for an agent to have justification to believe a proposition, it needs to be the case that the belief as possessed by the agent could exhibit certain epistemic good making features, e.g., the propositional content of the belief as possessed by the agent would be supported by the agent’s evidence. As I demonstrate, the fact that a proposition, p, is supported by an agent’s total evidence at a time, t, doesn’t guarantee that a belief in p as possessed by the agent at t could exhibit any epistemic good making features, including having propositional contents (i.e., p) that would be supported by the agent’s evidence. Thus, the fact that a proposition is supported by an agent’s evidence doesn’t guarantee that the agent has justification to believe the proposition. (shrink)

People frequently report that, at times, their thought has a vocal character. Thinking commonly appears to be accompanied or constituted by silently ‘talking’ to oneself in inner speech. In this paper, we explore the specifically epistemic role of inner speech in conscious reasoning. A plausible position—but one I argue is ultimately wrong—is that inner speech plays asolelyfacilitative role that is exhausted by (i) serving as the vehicle of representation for conscious reasoning, and/or (ii) allowing one to focus on certain types (...) of objects or relations, e.g., causal relations, abstracta, counterfactuals, etc., or to consciously entertain structured propositional contents that it would be hard (or impossible) to focus on or entertain with representations in other (e.g., imagistic) formats. According to this position, inner speech doesn't figure as a justificatory element in our reasoning or as the partial epistemic basis of our conclusions—it merely facilitates reasoning through (i) and/or (ii). In contrast to the view that inner speech is amerefacilitator, I establish that (outside of potentially playing roles (i) and/or (ii)) the language we use itself serves as a crucial source of information in reasoning. In other words, we reason from propositions about the language we use in inner speech as opposed to exclusively reasoning from the semantic contents of the speech. My conclusion follows from how we use language as a cognitive tool to keep track of information, e.g., the contents of premises, lemmas, previous reasoning results, etc., in reasoning. (shrink)

People frequently report that their thought has, at times, a vocal character. Thinking commonly appears to be accompanied or constituted by silently ‘talking’ to oneself in inner speech. In this paper, I argue that inner speech ‘utterances’ can constitute occurrent propositional attitudes, e.g., occurrent judgments, suppositions, etc., and, thereby, we can consciously reason through tokening a series of inner speech utterances in working memory. As I demonstrate, the functional role a mental state plays in working memory is determined in a (...) flexible and context sensitive manner by metacognitive monitoring and control procedures. An inner speech utterance functions as an occurrent judgment (and, thus, as a premise, lemma, or conclusion in a line of conscious reasoning) when it is experienced with a level of certainty that exceeds one’s threshold of confidence for acceptance. In virtue of an agent experiencing an inner speech utterance with a sufficient level of certainty, the utterance plays the functional role of an occurrent judgment through, e.g., terminating inquiry and causing overt actions (like overtly asserting the words rehearsed in inner speech).

This research examines the association between attitudes on cheating and cognitive moral development. In this research, we use Rest's (1979a) Defining Issues Test, the Attitudes on Honesty Scale (Authors) and Academic Integrity Index (Authors); the last two are adaptations of the DIT. A total of 220 students from three universities participated in the study (66 psychology majors and 154 business majors). The data indicate that 66.4 percent of the students reported that they cheated in high school, college, or both high (...) school and college. Psychology majors scored higher than business majors on both the Defining Issues Test (Rest, 1979a) and the Attitudes on Honesty Scale (AHS, Authors). Using factor analysis, we found significant associations between students' ratings of the importance considerations present in the three cheating scenarios and their estimates of whether cheating would occur (i.e., the Academic Integrity Index). Finally, using logistic regression, we found that the scores on the Attitudes on Honesty Scale and Academic Integrity Index associate with the self-reported cheating behavior of college students.

Background and aimsExcessive pain during medical procedures is a worldwide medical problem. Most scald burns occur in children under 6, who are often undermedicated. Adjunctive Virtual Reality distraction has been shown to reduce pain in children aged 6–17, but little is known about VR analgesia in young children. This study tests whether desktop VR can reduce the just noticeable pressure pain of children aged 2–10.MethodsA within-subject repeated measures design was used. With treatment order randomized, each healthy volunteer pediatric participant underwent (...) brief cutaneous pressure stimuli under three conditions: no distraction, a verbal color naming task, and a large TV-based desktop VR distraction. A hand-held Wagner pressure pain stimulation device was used to generate just noticeable pain sensations. Participants indicated when a steadily increasing non-painful pressure stimulus first turned into a painful pressure sensation.ResultsA total of 40 healthy children participated. Compared to the no distraction condition, the 40 children showed significant VR analgesia, t = 9.83, p < 0.001, SD = 6.24. VR was also significantly more effective at reducing pain sensitivity vs. an auditory color naming task, t = 5.42, p < 0.001, SD = 5.94. The subset of children aged 2–5 showed significant reductions in pain during VR. Children under 6 showed greater sensitivity to pain during no distraction than children aged 6–10.ConclusionDuring no distraction, children under 6 years old were significantly more sensitive to pain than children aged 6–10. Virtual reality significantly reduced the “just noticeable” pressure pain sensitivity of children in both age groups. (shrink)

Our conscious thought, at least at times, seems suffused with language. We may experience thinking as if we were “talking in our head”, thus using inner speech to verbalize, e.g., our premises, lemmas, and conclusions. I take inner speech to be part of a larger phenomenon I call inner semiotics, where inner semiotics involves the subjective experience of expressions in a semiotic (or symbol) system absent the overt articulation of the expressions. In this paper, I argue that inner semiotics allows (...) us to bootstrap our way into entertaining thoughts about exact numbers and quantities that we couldn't prior to our competence with a numeric code. I establish that our arithmetic thoughts literally occur as (internal ‘articulations’ of) expressions in a numeric code. However, a problem arises for my view: just as we can slip in overt speech, producing an utterance that deviates from what we mean to say, there is very good evidence that we can slip in inner speech as well. If our arithmetic thought occurs in a numeric code, it's far from clear how we determine when a covert utterance constitutes a slip. In closing, I provide an account of what makes an inner speech utterance a slip. (shrink)

In updating our beliefs on the basis of our background attitudes and evidence we frequently employ objects in our environment to represent pertinent information. For example, we may write our premises and lemmas on a whiteboard to aid in a proof or move the beads of an abacus to assist in a calculation. In both cases, we generate extramental (that is, occurring outside of the mind) representational states, and, at least in the case of the abacus, we operate over these (...) states in light of their contents (e.g., the integers represented by the beads) to generate new representations. In this paper, I argue that our belief updating processes and the grounds of their rational evaluation are partly constituted by extramental representations and operations. In other words, we don’t merely update our attitudes through an internal process of reasoning on the basis of available evidence. If we are to accurately understand and rationally evaluate our belief updating processes and resultant attitudes, we need to examine how we representationally appropriate our extramental environment in the updating process.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Being-Moved: Rhetoric as the Art of Listening by Daniel M. GrossNathaniel A. RiversBeing-Moved: Rhetoric as the Art of Listening. By Daniel M. Gross. Oakland: University of California Press, 2020. 260 pp. Paper $34.95. ISBN: 9780520340466.September 29, 2008. Radiohead front man Thom Yorke sits frustrated at his piano. Live on stage. He is trying to start a song, but something is tripping him up. The song is “Videotape,” and (...) he cannot start playing it. “Temporary loss of information,” he mumbles to an expectant crowd.The song “Videotape” is syncopated, meaning there is a “placement of rhythmic stresses or accents where they wouldn’t normally occur” (Wikipedia 2021). Practically, it means that Yorke is joining a song already in progress: there is a beat before the beat that “starts” the song. Yorke, then, is starting the song not on the down beat but after the down beat—after the song has already started. He needs to hear something before he can play anything. He needs to hear the beat before he can sing. “Give me the fuckin’ hi-hats only,” he asks.Yorke is moved by the drum and a beat not his alone. It is a beat preceding him to which he must become subject. He needs to listen, but it is a particular kind of listening: a passive listening that makes him, as it were, “subject to the instruction of others” (Gross 137).Like Yorke on stage in 2008, I struggled to start and write this review. Not for any fault in the book, which is clear and concise, complex and compelling, but because I wanted to write a review that practiced the art of listening Gross cultivates:Active listening [“auditor-as-judge”], as it is understood by theoreticians and practitioners of persuasion from classical antiquity through today, only takes off at dusk like Hegel’s owl of Minerva, leaving behind obscurities of our daily lives including our susceptibility [End Page 190] to advertising, our political apathy, our immersion in common-sense, our lovely credulity, our vulnerability to others, our very capacity to learn and change. We have much work ahead when it comes to the theoretical and practical nuances of listening in its passive dimensions.(137)This review practices listening to this call in this way. The worry remains that the genre of the book review tends toward what Gross identifies as active listening: the judge, the critic. I should probably be the “active listener-as-judge” (83). Surely, a good reviewer should protect future readers from a “bad teacher” (131). But how should a book review practicing passive listening read? Does it aim for learning? Surely. Credulity? Why not. Subjection? Hmm.... It is, after all, subjection that lies at the heart of Gross’s book. Subjection is the beat before the beat that is rhetoric, an art forever syncopated.There are many aspects of Gross’s argument, which I will hear out below, but key for me, and crucial for Gross’s argument, is his emphasis on passive dispositions (e.g., apathy, adherence, suggestibility, attentiveness, etc.) crucial to political formations and so vital to rhetoric. Being moved, toward which rhetoric (sacred rhetoric especially) bends, must admit not only to the prowess and power of the rhetor but also, necessarily, to the “basic vulnerability that lies at the heart of political agency itself ” (1). Indeed, “Rhetoric as a life science depends upon those lives affected” (8). Because of this dependence (and dependencies saturate the arts of listening), “rhetoric offers much more detail because it is the traditional domain where subjection is both theorized and practiced” (3).To articulate this offer, Gross works through what he describes as the “orphaned materials of modernity [that] often turn out to be vital strains of a different geology altogether” (12). Gross is here describing his own historiographic methodology. There are other things to hear in and about rhetoric. The core of his argument isn’t simply that listening is a practice important to rhetoric, with listening understood as a kind of critical facility—what Gross calls “active listener-as-judge” (83–84). Listening, for Gross, through his approach to Heidegger, bears upon being and becoming... (shrink)

Consider the following object, where, depending on how you are viewing this paper, the object may be a series of ink markings, a portion of a matrix of pixels through or from which light is emitted, etc.,augeLet’s call the object ‘Shape’. Is Shape a word token? If so, what word type is it a token of? Given how words are traditionally individuated, the Spanish, “auge”—meaning, apogee or peak—the French, “auge”—meaning, basin or bowl—and the German, “auge”—meaning, eye, are different words. So, (...) if Shape is a word token, is it a token of the Spanish, “auge”, the French, “auge”, the German, “auge”, or some combination of the three? Generalizing beyond Shape and ink markings/matrices of pixels as a potential medium for word tokens, when does something, f—e.g., some utterance, inscription, manual gesture, etc.—constitute a token of a word type, w, as opposed to some other word type, w *, or no word at all? In this paper, I motivate and place Central Question in the nascent and burgeoning subfield of the metaphysics of words. I argue that what makes something, f, a token of a word type, w, is that the process of generating f is explained and guided by one’s knowledge of w, e.g., one’s semantic, syntactic, morphophonological/orthographic, knowledge of w stored in one’s mental lexicon.

Kierkegaard has no comprehensive or systematic aesthetics of his own. Despite this, his work contains numerous and abundant references to the aesthetics of his time; namely, the Hegelian inspired aesthetics of Johan Ludvig Heiberg. As a one‐time adherent of Heiberg, Kierkegaard was thoroughly steeped in Heiberg's philosophy of art, and often merely applies such aesthetics to his selected objects of interest, echoing the philosophy of art of his day. There are, however, other instances where Kierkegaard carries out a sometimes overt (...) and sometimes covert critique of Heibergian aesthetics, especially after Either/Or, challenging his predecessor's views and the dominant aesthetics of the day.

In six experiments, we investigated the role of resource valence in intergenerational attitudes and allocations. We found that, compared to benefits, allocating burdens intergenerationally increased concern with one’s legacy, heightened ethical concerns, intensified moral emotions (e.g., guilt, shame), and led to feelings of greater responsibility for and affinity with future generations. We argue that, because of greater concern with legacies and the associated moral implications of one’s decisions, allocating burdens leads to greater intergenerational generosity as compared to benefits. Our data (...) provide support for this effect across a range of contexts. Our results also indicate that the differential effect of benefits versus burdens in intergenerational contexts depends on the presence of two important structural characteristics that help enact concerns about legacies, including (1) future impact of decisions, and (2) a self-other tradeoff. Overall, our findings highlight how considering resource valence brings to the fore a number of key psychological characteristics of intergenerational decisions—especially as they relate to legacies and ethics.

Prior research examining mate expulsion indicates that women are more likely to expel a mate due to deficits in emotional access while men are more likely to expel a mate due to deficits in sexual access. Prior research highlights the importance of accounting for measurement limitations (e.g., the use of incremental vs. forced-choice measures) when assessing attitudes toward sexual and emotional infidelity; Wade & Brown, 2012; Sagarin et al., 2012). The present research uses conjoint analysis, a novel methodology for (...) controlling several limitations of using continuous self-report measures in mate expulsion research. Participants (N = 181; 128 women) recruited from Bucknell University and several psychology recruitment listservs in the US rated 9 profiles that varied in three potential levels of emotional and sexual accessibility. Men were more likely to want to break up with a partner due to sexual accessibility deficits, whereas women were more likely to want to break up due to emotional accessibility deficits. However, regardless of sex, emotional inaccessibility was more likely to produce mate expulsion. These findings are consistent with prior theory and highlight the need to disentangle emotional accessibility into its constituent in-pair benefits. This research also illustrates the utility of conjoint analysis as a statistical tool for studying how humans resolve trade-offs among competing outcomes during romantic decision-making. (shrink)

Certain social context features (e.g., maternal presence) are known to increase young children's exploration, a key process by which they learn. Yet limited research investigates the role of social context, especially peer presence, in exploration across development. We investigate whether the effect of peer presence on exploration is mediated by age or cultural‐specific experiences. We test its impact on exploration across development (2–11 years) and across cultures (United States and the Tsimane', indigenous farmer‐foragers in Bolivia). Specifically, peer presence does not (...) boost exploration among young U.S. children and becomes more inhibitory among school‐age children. In contrast, peer presence facilitates exploration and provides an additional boost for older Tsimane' children, who differ from U.S. children in their cultural‐specific learning experiences (e.g., formal education), among other differences. We discuss potential cultural factors and mechanisms by which peer presence may boost exploratory behavior. (shrink)

It was shown in Dirac A117, 610; A118, 351, 1928) that the ultra-violet divergence in quantum electrodynamics is caused by a violation of the time-energy uncertainly relationship, due to the implicit assumption of infinitesimal time information. In Wheeler et al. it was shown that Einstein’s special theory of relativity and Maxwell’s field theory have mathematically equivalent dual versions. The dual versions arise from an identity relating observer time to proper time as a contact transformation on configuration space, which leaves phase (...) space invariant. The special theory has a dual version in the sense that, for any set of n particles, every observer has two unique sets of global variables \\) and \\) to describe the dynamics, where \ is the canonical center of mass. In the \\) variables, time is relative and the speed of light is unique, while in the \\) variables, time is unique and the speed of light is relative with no upper bound. In the Maxwell case, the two sets of particle wave equations are not equivalent. The dual version contains an additional longitudinal radiation term that appears instantaneously with acceleration, leading to the prediction that radiation from a cyclotron will not produce photoelectrons. A major outcome is the dual unification of Newtonian mechanics and classical electrodynamics with Einstein’s special theory of relativity, without the need for point particles, without a self-energy divergency and, without need for the problematic Lorentz–Dirac equation. The purpose of this paper is to introduce the dual theory of relativistic quantum mechanics. In our approach, we obtain three distinct dual relativistic wave equations that reduce to the Schrödinger equation when minimal coupling is turned off. We show that the dual Dirac equation provides a new formula for the anomalous magnetic moment of a charged particle. We can obtain the exact value for the electron g-factor and phenomenological values for the muon and proton g-factors. (shrink)

A new reading of a crucial chapter in the history of social and political thought – the transition from the late Enlightenment to early liberalism.

The US populace appears to be increasingly polarized on partisan lines. Political fissures bifurcate the country even on empirical matters like vaccine safety and anthropogenic climate change. There now exists an ever-expanding interdisciplinary research program in which theorists attempt to explain increases in political polarization and myriad other phenomena collected under the “post-truth” heading by appeal to social-epistemic structures, like echo chambers and epistemic bubbles, that affect the flow and uptake of information in various communities. In this paper, I critically (...) analyze C. Thi Nguyen’s important and popular analysis of echo chambers and epistemic bubbles. As I demonstrate, the explanatory mechanisms on which Nguyen focuses are, arguably, overly cognitive and obscure significant effects of social-epistemic structures on our affective lives. The broader lesson to draw from my discussion is the following: commonly used expressions intended to refer to social-epistemic problems, like “political polarization”, possess no univocal definition across theorists, and various ways of making the terms precise are differentially successful in characterizing verifiable phenomena. Theorizing about social-epistemic structures should be responsive to relevant empirical work on various phenomena that we have good reason to believe constitute real and substantive problems that result from the flow and uptake of information.

The mesostriatal dopamine system is prominently implicated in model-free reinforcement learning, with fMRI BOLD signals in ventral striatum notably covarying with model-free prediction errors. However, latent learning and devaluation studies show that behavior also shows hallmarks of model-based planning, and the interaction between model-based and model-free values, prediction errors, and preferences is underexplored. We designed a multistep decision task in which model-based and model-free influences on human choice behavior could be distinguished. By showing that choices reflected both influences we could (...) then test the purity of the ventral striatal BOLD signal as a model-free report. Contrary to expectations, the signal reflected both model-free and model-based predictions in proportions matching those that best explained choice behavior. These results challenge the notion of a separate model-free learner and suggest a more integrated computational architecture for high-level human decision-making. (shrink)
