The previous studies have shown that human infants and domestic dogs follow the gaze of a human agent only when the agent has addressed them ostensively—e.g., by making eye contact, or calling their name. This evidence is interpreted as showing that they expect ostensive signals to precede referential information. The present study tested chimpanzees, one of the closest relatives to humans, in a series of eye-tracking experiments using an experimental design adapted from these previous studies. In the ostension (...) conditions, a human actor made eye contact, called the participant’s name, and then looked at one of two objects. In the control conditions, a salient cue, which differed in each experiment (a colorful object, the actor’s nodding, or an eating action), attracted participants’ attention to the actor’s face, and then the actor looked at the object. Overall, chimpanzees followed the actor’s gaze to the cued object in both ostension and control conditions, and the ostensive signals did not enhance gaze following more than the control attention-getters. However, the ostensive signals enhanced subsequent attention to both target and distractor objects (but not to the actor’s face) more strongly than the control attention-getters—especially in the chimpanzees who had a close relationship with human caregivers. We interpret this as showing that chimpanzees have a simple form of communicative expectations on the basis of ostensive signals, but unlike human infants and dogs, they do not subsequently use the experimenter’s gaze to infer the intended referent. These results may reflect a limitation of non-domesticated species for interpreting humans’ ostensive signals in inter-species communication. (shrink)

Teaching is hypothesized to be a species-typical behavior in humans that contributed to the emergence of cumulative culture. Several within-culture studies indicate that foragers depend heavily on social learning to acquire practical skills and knowledge, but it is unknown whether teaching is universal across forager populations. Teaching can be defined ethologically as the modification of behavior by an expert in the presence of a novice, such that the expert incurs a cost and the novice acquires skills/knowledge more efficiently or that (...) it would not acquire otherwise. One behavioral modification hypothesized to be an adaptation for teaching is ostensive communication—exaggerations of prosody and gesture that signal intent to transmit generalizable knowledge and indicate the intended receiver. On this view, the use of ostensive communication in conjunction with the transmission of generalizable knowledge constitutes evidence of teaching. Oral storytelling appears to meet these criteria: Indigenous peoples regard their traditions as important sources of ecological and social knowledge, and oral storytelling is widely reported to employ paralinguistic communication. To test this hypothesis, descriptions of performed narrative in forager societies were coded for the use of 14 ostensive-communicative behaviors and the presence of generalizable knowledge. Although biased toward North America, the study sample comprised 53 forager cultures spanning five continents, 34 language families, and diverse biomes. All cultures evinced the predicted behaviors. Results suggest that foragers use storytelling as a mode of instruction, thus providing cross-cultural evidence of teaching in forager populations. (shrink)

Communication, when defined as an act intended to affect the psychological state of another individual, demands the use of inference. Either the signaler, the recipient, or both must make leaps of understanding which surpass the semantic information available and draw from pragmatic clues to fully imbue and interpret meaning. While research into human communication and the evolution of language has long been comfortable with mentalistic interpretations of communicative exchanges, including rich attributions of mental state, research into animal communication has balked (...) at theoretical models which describe mentalized cognitive mechanisms. We submit a new theoretical perspective on animal communication: the model of inferential communication. For use when existing proximate models of animal communication are not sufficient to fully explain the complex, flexible, and intentional communication documented in certain species, specifically non-human primates, we present our model as a bridge between shallower, less cognitive descriptions of communicative behavior and the perhaps otherwise inaccessible mentalistic interpretations of communication found in theoretical considerations of human language. Inferential communication is a framework that builds on existing evidence of referentiality, intentionality, and social inference in primates. It allows that they might be capable of applying social inferences to a communicative setting, which could explain some of the cognitive processes that enable the complexity and flexibility of primate communication systems. While historical models of animal communication focus on the means-ends process of behavior and apparent cognitive outcomes, inferential communication invites consideration of the mentalistic processes that must underlie those outcomes. We propose a mentalized approach to questions, investigations, and interpretations of non-human primate communication. We include an overview of both ultimate and proximate models of animal communication, which contextualize the role and utility of our inferential communication model, and provide a detailed breakdown of the possible levels of cognitive complexity which could be investigated using this framework. Finally, we present some possible applications of inferential communication in the field of non-human primate communication and highlight the role it could play in advancing progress toward an increasingly precise understanding of the cognitive capabilities of our closest living relatives.

Although the popularity of Humane Education Programs as a method of teaching compassion and caring for all living beings is increasing, there is a need for rigorous, methodologically sound research evaluating the efficacy of HEP. Recent calls for the inclusion of HEP within broader humanistic, environmental, and social justice frameworks underline the importance of HEP beyond a simple “treatment of animals” model. Lack of methodological rigor in the majority of published HEP studies and dispersal across disparate fields , however, means (...) that there is a potential for the popular use of HEP to outstrip our understanding of the variables that impact efficacy. The current study discusses some of these issues and presents a pilot study of a literature-only HEP intervention. Comparisons with an age-matched control group indicated that the four-week HEP resulted in an increase in measures of empathy and treatment of animals, although only the increase in empathy levels was significant. This paper discusses the implications of the current results and areas in need of future consideration. (shrink)

Paramedics encounter ethical dilemmas at work, and while previous research has improved ethics education and practice, more can be learned from the lived experience of paramedics facing ethical challenges. This paper explores the lived experience of two paramedics, one with five years’ experience, the other twenty, presented with comparable cases. The participants, who were interviewed in a broader qualitative study exploring practical wisdom, were asked to select a case involving ethical decision-making from their own practice experience. Semi-structured interviews employed the (...) five-step Critical Decision Method as a framework to explore various aspects of the decision-making process. The two cases were identified as exemplars of prominent themes suitable for discussion. The findings highlighted several factors that influence paramedic ethical decision-making, including practical wisdom, communication and teamwork, clinical support, and education. This case comparison identifies a greater need to focus education on the fostering of practical wisdom, and the development of non-technical skills such as communication and teamwork, supported by interprofessional education endeavours. Furthermore, greater access to support for paramedics must be available to further evolve practical wisdom. The combination of improved education and support will likely cater for the full spectrum of ethical challenges faced by paramedics in their work. (shrink)

In Australia, paramedics are obliged to practice ethically. Graduates of baccalaureate degrees in paramedicine should therefore possess a common grounding in ethics to meet the professional capabilities expected of registered paramedics. However, there is a lack of clarity regarding ethics education for paramedicine students, including what is taught, how it is taught, and how it is assessed. This paper explores ethics education for paramedicine students in Australia, how it aligns with current professional expectations, and how it may be enhanced. Point-in-time (...) data regarding ethics education was collected from websites of fifteen Australian universities offering undergraduate baccalaureate degrees in paramedicine. Data collection was supported by consultation with academics from several institutions. Content analysis was utilised to categorise and analyse data to explore similarities and differences in curricula. Similarities included approaches to learning and teaching and the use of case-based learning, with variability found across teaching staff profiles and content areas. Findings suggest it is time for collaboration to develop a model ethics curriculum for paramedicine students in Australia. (shrink)

I make three related proposals concerning the development of receptive communication in human infants. First, I propose that the presence of communicative intentions can be recognized in others' behaviour before the content of these intentions is accessed or inferred. Second, I claim that such recognition can be achieved by decoding specialized ostensive signals. Third, I argue on empirical bases that, by decoding ostensive signals, human infants are capable of recognizing communicative intentions addressed to them. Thus, learning (...) about actual modes of communication benefits from, and is guided by, infants' preparedness to detect infant-directed ostensive communication. (shrink)

Paul Grice’s theory of meaning has been widely adopted as a starting point for investigating the evolutionary and developmental emergence of linguistic communication. In this picture, reasoning about complexes of intentions is a prerequisite for communicating effectively at the prelinguistic level, as well as for acquiring a natural language. We argue that this broadly ‘Gricean’ picture rests on an equivocation between theories of communication and theories of cognition, and that it leads to paradoxical or implausible claims about human psychology. We (...) defend an alternative conception of prelinguistic communication, inspired by Bart Geurts and based on the notion of commitment. Adopting a commitment-first approach makes it possible to avoid the pernicious equivocation, and it provides a better systematization of the key empirical findings. We develop our argument with respect to infants’ sensitivity to ‘ostensive signals’; infants’ pointing; and infants’ endorsement of normative attitudes in joint activities. Finally, adopting a commitment-first approach makes it possible to argue that sophisticated forms of psychological reasoning are enabled by the mastery of a rich natural language, rather than being a prerequisite for acquiring one.

According to the theory of natural pedagogy, humans have a set of cognitive adaptations specialized for transmitting and receiving knowledge through teaching; young children can acquire generalizable knowledge from ostensive signals even in a single interaction, and adults also actively teach young children. In this article, we critically examine the theory and argue that ostensive signals do not always allow children to learn generalizable knowledge more efficiently, and that the empirical evidence provided in favor of the (...) theory of natural pedagogy does not defend the theory as presented, nor does it support a weakened version of the theory. We argue that these problems arise because the theory of natural pedagogy is grounded in a misguided assumption, namely that learning about the world and learning about people are two distinct and independent processes. If, on the other hand, we see the processes as interrelated, then we have a better explanation for the empirical evidence. (shrink)

The standard cognitive explanation for the emergence of human communication is that it rests largely on the expression and attribution of communicative intentions which are, in turn, enabled by complex metarepresentations of mental states. This complexity is at odds with the limited metapsychological abilities of infants. But mentalistic metarepresentations are neither necessary nor sufficient in explaining communication. Coded ostensive signals (e.g., eye contact) and established channels (e.g., speech) allow that communicative episodes be identified through decoding rather than metarepresentational (...) inferences. Thus, some metarepresentations may be unnecessary. However, metapsychology is also insufficient for explaining communication: the logic of instrumental actions permits interpreting their effect as following from intentions, yet the effect of communicative actions is often unavailable for inferring meaning. Moreover, current evidence for the developmental trajectory of communication and mental state attribution does not support the emergence of the former from the latter. My proposal is that our primitive concept of communication targets, instead, representational action. When we communicate, we typically convey a propositional content that is detached from our acts—a property absent in ordinary goal-directed actions. This view additionally raises the possibility that metarepresentational capacities evolved for representing external, communicative representations and were only later exapted for other purposes. (shrink)

Natural Pedagogy refers to social learning based on ostensive communication between adults and infants which results in rapid and efficient transmission of cultural information. The theory predicts that children are able to recognize communicative intention when adults address them using ostensive signals. Furthermore, natural pedagogy predicts that infants ascribe the knowledge they have acquired to others according to what is called the “assumption of universality”. In other words, infants are able to ascribe informative contents to others even (...) when they are outside the bounds of the learning context. Although Csibra and Gergely have so far denied any type of relationship between natural pedagogy and mindreading capacities, I suggest that early mindreading capacities are components of the natural pedagogy system, as recent experimental findings on early Theory of Mind abilities appear to show.

The suite of secretive national security programs initiated in the US since 9/11 has created debate not only about the merits of targeted killing, torture, secret detention, cyberwar, global signals intercepts, and data-mining, but about the very secrecy in which these programs were conceived, debated by government officials, and implemented. Law must be revealed to those who are expected to comply with its demands. Law is a mere pretext for coercion if the laws permitting the government to coerce people (...) for non-compliance are concealed. The purpose of this essay is to determine whether inhabitants of a liberal state—a type of state tracing the legitimacy of its coercive actions to the consent of the governed—also need to know the internal protocols and legal findings of the government agencies ostensibly serving them. To put this question another way, what, if anything, may government agencies in liberal states keep secret? (shrink)

Recent discussions of animal communication and the evolution of language have advocated adopting a ‘pragmatics-first’ approach, according to which “a more productive framework” for primate communication research should be “pragmatics, the field of linguistics that examines the role of context in shaping the meaning of linguistic utterances”. After distinguishing two different conceptions of pragmatics that advocates of the pragmatics-first approach have implicitly relied on, I argue that neither conception adequately serves the purposes of pragmatics-first approaches to the origins of human (...) linguistic communication. My main aim in this paper is to motivate–and begin to articulate–an intermediary conception whose scope is narrower than Carnapian pragmatics but broader than Gricean pragmatics. To do so, I first spell out what I take to be the key insight offered by proponents of the Gricean approach concerning the emergence of linguistic communication, namely, its being communication ‘from a psychological point of view’. I then develop this insight using key elements from the anti-Gricean ‘biosemantic’ account of linguistic communication due to Ruth Millikan, Philosophical Perspectives 9, Ridgeview Publishing, Atascedero CA, 1995, Millikan R Varieties of Meaning. Mass.: The MIT Press, Cambridge, Millikan, Beyond concepts: unicepts, language, and natural information, Oxford University Press, Oxford UK, 2017, and elsewhere). I argue that the intermediary pragmatics-first approach that I propose, which draws on both Gricean and Millikanian resources, would be better equipped to serve the purposes of those who search for potential precursors of human linguistic communication in animal communication.

continent. 1.2 (2011): 125-128. What is the nature of sound? What is the nature of volume? William James, in attempting to address these simple questions wrote, “ The voluminousness of the feeling seems to bear very little relation to the size of the ocean that yields it . The ear and eye are comparatively minute organs, yet they give us feelings of great volume” (203-­4, itals. original). This subtle extensivity of sensation finds its peer in the subtle yet significant influence (...) of habituated action upon our lives. This expansive quality of habit­making is what Craig Dongoski's bodies of work enable us to appreciate. Nearly ten years ago Dongoski had a habit of turning on his audio recorder every day at three o'clock for three minutes. No matter what the setting, what the activity, Dongoski recorded the ambient sounds in his environment at that moment. As it happened, one day he was teaching a drawing class and he recorded the sounds of their pencils scratching across their respective surfaces. This was a critical moment for him. Later he would place a contact mic onto a drawing surface and record the sound of his signature. Signatures change over time, they respond to the conditions in which they are performed. Signatures speak volumes about the author, but a practice of attunement is required for the volume to be audible. To hear all that a signature can tell about its author, the listener must tune into the frequency at which this information is being broadcast. Dongoski's drawings and video works draw­out the peculiar artifact that habit makes of living: habits establish a tempo of living and it seems that one's habitus is the signature of habitual living. I sat down with Craig in an attempt to sound­out some of the depths of thought in his practice. What follows is selected from our conversation. Paul Boshears (PB): Clearly your work is dealing with time: from the painstaking action of rendering the drawing to the free­form approach of launching a microphone into a body of water and waiting to see what's recorded. Craig Dongoski (CD): Are we talking about the films or the drawings? PB: Well, it's a bit of both in my mind. I know the drawings on first glance seem to be these flows of lines without concern but I realize that there is this painstaking action involved. CD: I'm interested in time because I'm interested in forms outside of control, outside of politics, and outside of economics. I think that art, when it's alive, does go beyond those. I'm interested in duality and paradox—a stream of contradiction, I suppose. For instance, scale and size. There is a tendency to think that these are the same thing. But really you can have something small that has a lot of scale—look at Goya's drawings, Los Caprichos , they're very small but they have a lot of scale. Likewise things that are spontaneous don't necessarily mean that they take only two or three seconds to do. This latter distinction is what I'm most interested in. Having that appearance of spontaneity. The image has rhythm, you can latch onto it; but the reality is that it took many hours—and many months in some cases—to arrive at. And this is in keeping with geological time. I like to insert this series of thoughts into my work sometimes as an attempt to make some of this stuff comprehensible. There are all these distractions inundating us throughout our days now. Time gets tweaked by all these technologies that we interact with daily. There's more than just digital time or the mechanical time of your watch. There's biological time, that time in which you're growing. PB: I'm reminded of McLuhan here: he made his career by making that strong claim that the humans of today are not the same humans of three generations ago because technology has fundamentally changed us. Are we not the same human beings as a hundred years ago? CD: I mean, I don't think we're the same human beings that we were when he was around! It's my understanding that before painting a flower, monks would meditate for hours on that flower and then they would complete the painting of that flower in less than a minute. That's what I want to point out about our world today, we have all this information, but how much of it are we metabolizing? PB: Is there a message you're looking for? Or that you're trying to share? CD: These drawings set­up the circumstances for me to continue them forever. I'm only about six years into it, but with more time, things can unfold. You know? If you take this cup of coffee and vow to restrict your work to only this material and medium for seven years—you'll make interesting work. The problem is that most people can't hold on to things or they give up or they get distracted. They don't trust that anything is possible; anything is potential material. Staying with this cup of coffee example, we can get enveloped in the history of the recycling logo, or the process for harvesting coffee and so on. The same is true for my work as it has lead me into places like graphical music scores. I had, of course, known about John Cage's notations and I'd always been interested in sound itself, but this drawing practice made it feasible to explore the intersections in a meaningful way. I think that if you trust your instincts and your curiosities and your abilities, then the bus drives itself. Look at Roman Opalka, he's kind of the patron saint of time painting. The claim is that no one can count to a billion in a lifetime so he's set­out to paint to seven sevens (7,777,777). He began with white numbers on a black field but over the years he has gradually reduced the black field to ever­lightening grays. His plan is to paint these seven sevens on what ostensibly will be white on white. PB: It occurs to me that I've never thought of the actual, literal, meaning of “microphone” in relation to “microscope.” The mic has made everything loud, the world's not allowed to be quiet anymore. Maybe we should call them “macrophones” since telephone's already taken... CD: Well, a microscope is a lens. What got me interested in sound was that a microphone acts like a lens. There are wide angle lenses, or a lens that gets your eye up close to something far away, or at a tiny level. The same is true of the microphone. You can use a parabolic mic to hear what the coach is saying on a sports field or a mic that picks­up the sound from the entire cathedral. There's this whole gamut... I'm kind of playing with the words here. I'm into the minuteness of the sound, but I'm interested in the minuteness of the mark itself. PB: I guess it's a Deluezean, generative, statement, then? It's not a metaphor, it's an actual thing with which we can work. CD : That's right. PB: While doing some background work on you I found myself at interesting places on the internet. For example, Konstantin Raudive and a brief jog into Electronic Voice Phenomena (EVP); perhaps this was just synchronicity. But, it's a happy coincidence nonetheless because the them of this issue of continent. is “the moraine” and one of the nuances of this term is “what remains.” Is there a metaphysical or epistemological problem that you're sorting­out here? CD: Think about fossils: fossils are the first recording device, you know? It's the first, natural, recording device. It's in this way that I think my works are fossilized time. Artifacts of that process. Van Gogh is a strong source for me in this regard: it's not what he's painting it's how. You're seeing his nervous system at work. The what is so incidental, the chairs, the flowers, etc. It's funny: when I first started doing this, before I started drawing voices, I was doing these things in cemeteries. I was doing automatic drawings. And when I took this experiment to its maximum I was taking hydrophones and burying them in abandoned graves. I was thinking about the mic rig as the south coordinate and I'd use a shortwave radio as the north coordinate. Usually it was just white noise, but on the east and west I'd station a writer and a drawer. So I'd have these things going on simultaneously and I'd be mixing them at the same time. PB: How'd it come out? CD: Well, just like you'd expect. It was a lot of white noise. But I think that Raudive was on to something. Burroughs used to say something similar when he'd talk about being in a foreign country where he didn't know the language and then he'd start to hear things. At the base, what I'm doing is pattern recognition. I do have a writing component to the drawings. I haven't exploited it in a while but... I use a vocoder, which was developed to encrypt spy signals during one of the World Wars. The mechanism takes two channels, one being the spy's signal combined with noise and then the other channel is a sine wave so that the intended recipient can pick out the words. So I did something like this with Beowulf. I tried combining the spoken word with other television and radio sources, but that didn't work because a book on tape is usually read in a very steady clip and the result was too garbled. So the second try, instead of drawing I was writing, trying to articulate the sounds that I could hear in this garbled transmission of Beowulf. You start to think you hear something, so you start to write what you think you're hearing. But what you're hearing is just being triggered by this articulating action. When the sound of the drawing lines up with the sound of the word you get something. But it's not ever what you're really hearing. You start writing and you're trying to keep up with what you think you're hearing and it is truly, in the most true sense of the phrase, automatic writing. You can contrive and go into a “spirit trance” or whatever, but... PB: It's uninteresting to you? CD: Well, it's unbelievable. It's just listening to sounds and following along. The magic is out there, there are no tricks or anything. You do this exercise with twenty people and you will get twenty totally different writings. But, you're creating the sound and you're creating the writing as an interpretation. That's the thing with EVP, it's homophonic translation. PB: Do you trust a straight line? I know you start with these meticulous lines at the beginning of the drawings but they do change over time. CD: I'm trying to show that there are these imperfections in structures and that over the reiterations of these structures these imperfections become amplified. But you can see them in tree formation as well. The rings alter their shape as the trees grow. PB: Is that your transmission then? You're not just receiving these sounds but you're broadcasting this message as well? CD: Things exist because of their opposites. These drawings are really about nothing. It's the first body of work I've had where people project so much of stuff onto the works. So there you go, things existing because of their opposites. It's kind of like with Mike Kelley: the work was about a critique of commodity culture and commodifying emotions. Using toys this was a critique of production. But then suddenly people were saying it was about abuse and the abuse that Mike Kelley had suffered. And it wasn't but he heard that and said, “I'll go with it,” and so he did. I think that's the nature of communication: I send this but you receive that instead and this makes me think about what I sent in a different way. (shrink)

Various claims regarding intertheoretic reduction, weak and strong notions of emergence, and explanatory fictions have been made in the context of first-order thermodynamic phase transitions. By appealing to John Norton’s recent distinction between approximation and idealization, I argue that the case study of anyons and fractional statistics, which has received little attention in the philosophy of science literature, is more hospitable to such claims. In doing so, I also identify three novel roles that explanatory fictions fulfill in science. Furthermore, I (...) scrutinize the claim that anyons, as they are ostensibly manifested in the fractional quantum Hall effect, are emergent entities and urge caution. Consequently, it is suggested that a particular notion of strong emergence signals the need for the development of novel physical–mathematical research programs. (shrink)

Rape and sexual assault are major problems. In the majority of sexual assault cases consent is the central issue. Consent is, to borrow a phrase, the ‘moral magic’ that converts an impermissible act into a permissible one. In recent years, a handful of companies have tried to launch consent apps which aim to educate young people about the nature of sexual consent and allow them to record signals of consent for future verification. Although ostensibly aimed at addressing the problems (...) of rape and sexual assault on university campuses, these apps have attracted a number of critics. In this paper, I subject the phenomenon of consent apps to philosophical scrutiny. I argue that the consent apps that have been launched to date are unhelpful because they fail to address the landscape of ethical and epistemic problems that arise in the typical rape or sexual assault case: they produce distorted and decontextualised records of consent which may in turn exacerbate the other problems associated with rape and sexual assault. Furthermore, because of the tradeoffs involved, it is unlikely that app-based technologies could ever be created that would significantly address the problems of rape and sexual assault. (shrink)

ISSUE DESCRIPTION The The Journal of Scientific Exploration is devoted to the open-minded examination of scientific anomalies and other topics on the scientific frontier. Its articles and reviews, written by authorities in their respective fields, cover both data and theory in areas of science that are too often ignored or treated superficially by other scientific publications. This issue of the journal features papers on a variety of subjects. The lead article presents the results of an innovative ball-selection test for ESP, (...) including a successful replication under tighter and presumably more repressive conditions under skeptical supervision at the University of London. The next paper presents a double-blind study of apparent short-term precognition in Bengalese finches. The test tracked whether the birds displayed alarm behavior prior to the random display of a crawling snake video. The third paper discusses an original approach to the study of ostensible macroscopic psychokinetic phenomena produced in a mediumistic sitter-group setting. The participants tried to generate a pseudo-spirit similar to that in the famous Philip experiments, and the researchers deployed various strategies for detecting and measuring physical correlates of the phenomena observed during the sessions. The fourth paper reports an attempt to use random number generators to detect field consciousness while people watched a film in a movie theater. In the fifth paper, researchers report a study that used advanced signal-processing techniques and instantaneous EEG phase coupling to examine interpersonal connectivity between healer and subject. The final paper presents two studies designed to illustrate how laboratory ESP effects might be used to predict real-world, practical events--in this case, the behavior of sets of financial indices. This issue of the JSE is then filled out, as usual, with a large selection of substantive book reviews. (shrink)

It is widely assumed in philosophy that there is a tight connection between semantics and metaphysics. Semantic theories about the meanings of natural language terms and phrases are taken to provide evidence for and against various metaphysical theses about the nature of non-linguistic parts of the world. Call this view the widespread thesis. I argue that the widespread thesis is mistaken: semantic theories do not generally have robust metaphysical consequences. I contend that the best arguments for the widespread thesis turn (...) on an interpretation of semantic theories according to which they are metaphysically illuminating: the metaphysical structure of the world is directly mirrored in the structure of the theory. Terms and existential quantification in the theory signal the existence of entities in the world, predicates signal the existence of properties, and the structures of set theoretic objects invoked by the theory directly correspond to structural features of the world. Such an interpretation is not the only one available, however, and it is a substantive philosophical (and linguistic) issue which interpretation is correct. Accordingly, I develop and defend an alternative interpretation of semantic theories according to which the structural features of these theories and of their theorems reflect biological and computational constraints on the architecture of the language faculty and historical contingencies in its evolutionary development. Supposedly metaphysically committing features of the theory—including the appearance of quantification and (ostensibly) referring terms—may thus be arepresentational artifacts of these constraints, rather than representational features that reflect metaphysical reality. To determine the metaphysical consequences of a semantic theory then, we must determine which of its features represent language-independent characteristics of the world and which are arepresentational consequences of the structure of the language faculty. To do this, however, we must have some prior idea what the language-independent world is like—that is, we must engage in prior metaphysical theorizing that is not beholden to the semantic theory itself.

Previous research has shown that although infants follow the gaze direction of robots, robot gaze does not facilitate infants’ learning for objects. The present study examined whether robot gaze affects infants’ object learning when the gaze behavior was accompanied by verbalizations. Twelve-month-old infants were shown videos in which a robot with accompanying verbalizations gazed at an object. The results showed that infants not only followed the robot’s gaze direction but also preferentially attended to the cued object when the ostensive (...) verbal signal was present. Moreover, infants showed enhanced processing of the cued object when ostensive and referential verbal signals were increasingly present. These effects were not observed when mere nonverbal sound stimuli instead of verbalizations were added. Taken together, our findings indicate that robot gaze accompanying verbalizations facilitates infants’ object learning, suggesting that verbalizations are important in the design of robot agents from which infants can learn. Keywords: gaze following; humanoid robot; infant learning; verbalization; cognitive development. (shrink)

Long before the emergence of the modern brand economy, Thorstein Veblen elaborated an economic theory centered on symbolic entities. Based on his thought, this article pursues a view of the brand which escapes both sociological and economic approaches to the phenomenon. Views of the brand as a meaningful object and of the trademark as a signal of product quality omit the simple possibility that the brand, to some extent, is a symbol turned into a commodity. The article develops this possibility (...) using Veblen’s economic theory of display, which can be read as revolving around the notion of a ‘costly symbol’. Things which necessitate waste, and thus materially attest to wealth, enter Veblen’s economy of display insofar as they become valued for their own sake. His theory thus foretells the basic transformation that characterizes the emergence of modern brand economy, where symbols which ostensibly qualified commodities became by themselves economic objects.

Children’s cognitive and language development is a central aspect of human development and has wide and long-standing impact. The parent-infant relationship is the chief arena for the infant to learn about the world. Studies reveal associations between quality of parental care and children’s cognitive and language development when the former is measured as maternal sensitivity. Nonetheless, the extent to which parental mentalizing – a parent’s understanding of the thoughts, feelings, and attitudes of a child, and presumed to underlie sensitivity – (...) contributes to children’s cognitive development and functioning, has yet to be thoroughly investigated. According to the epistemic trust theory, high mentalizing parents often use ostensive cues, which signal to the infant that they are perceived and treated as unique subjective beings. By doing so, parents foster epistemic trust in their infants, allowing the infant to use the parents a reliable source of knowledge to learn from. Until recently, parental mentalizing has been limited to verbal approaches and measurement. This is a substantial limitation of the construct as we know that understanding of intentionality is both non-verbal and verbal. In this investigation we employed both verbal and non-verbal, body-based, approaches to parental mentalizing, to examine whether parental mentalizing in a clinical sample predicts children’s cognitive and language development 12 months later. Findings from a longitudinal intervention study of 39 mothers and their infants revealed that parental embodied mentalizing in infancy significantly predicted language development 12 months later and marginally predicted child cognitive development. Importantly, PEM explained unique variance in the child’s cognitive and linguistic capacities over and above maternal emotional availability, child interactive behavior, parental reflective functioning, depression, ethnicity, education, marital status, and number of other children. The theoretical, empirical, and clinical implications of these findings are discussed. (shrink)

Peter Berger established himself in the sociological profession in large part through his functional interpretations of religion and its ostensible demise in relation to the empirical bent of modern intellectual thought. Yet, in his ef–fort to expand the scope of empiricism such that it might address nontrivial concerns, Berger found himself attempting to understand the “substance” of religiori—that is, the conviction that there exists an “other” which confronts us unconditionally and consequently forms the basis of all issues concerning value and (...) meaning. Berger's writings deserve critical attention in that they disclose both the problems and the promises of utilizing empirical methods for the task of rehabilitating, rather than debunking, humanity's religious propensities.

Resistance to inhibitors of cholinesterase 8A (Ric‐8A) is a prominent non‐receptor GEF and a chaperone of G protein α‐subunits (Gα). Recent studies shed light on the structure of Ric‐8A, providing insights into the mechanisms underlying its interaction with Gα. Ric‐8A is composed of a core armadillo‐like domain and a flexible C‐terminal tail. Interaction of a conserved concave surface of its core domain with the Gα C‐terminus appears to mediate formation of the initial Ric‐8A/GαGDP intermediate, followed by the formation of a (...) stable nucleotide‐free complex. The latter event involves a large‐scale dislocation of the Gα α5‐helix that produces an extensive primary interface and disrupts the nucleotide‐binding site of Gα. The distal portion of the C‐terminal tail of Ric‐8A forms a smaller secondary interface, which ostensibly binds the switch II region of Gα, facilitating binding of GTP. The two‐site Gα interface of Ric‐8A is distinct from that of GPCRs, and might have evolved to support the chaperone function of Ric‐8A. (shrink)

The basic premise of biosemiotics as a discipline is that there are elementary processes linking signifying strategies in all forms of animate life. Correspondingly, the discoveries of biosemiotics should, in principle, be capable of revealing new insights about human signification. In the present article, I show that this is in fact the case by constructing a biosemiotic model that links advertising strategies with corresponding structures in animal predation. The methodological framework for this model is the catastrophe theory of René Thom. (...) The end result is a revised understanding of an ostensibly cultural phenomenon that demonstrates its continuity with signalling processes conventionally associated with the natural world. (shrink)

Pangle’s thesis is that Aristotle’s account of friendship in Nicomachean Ethics 8 and 9 addresses multiple audiences. For his ostensible audience, statesmen and other men of action, Aristotle paints an enticing picture of friendship that is based on moral virtue and issues in acts of benevolence. However, he embeds within this analysis subtle “tensions” designed to signal to thoughtful readers the limits of moral virtue and so to provoke them to pursue a philosophical life as well as to provide them (...) the material for philosophical contemplation. Pangle thinks that this second group, potential philosophers, is Aristotle’s principal audience, even if unannounced. (shrink)

In this paper, I am going to cast doubt on an idea that is shared, explicitly or implicitly, by most contemporary pragmatic theories: that the inferential interpretation procedure described by Grice, neo-Griceans, or post-Griceans applies only to the interpretation of ostensive stimuli. For this special issue, I will concentrate on the relevance theory (RT) version of this idea. I will proceed by putting forward a dilemma for RT and argue that the best way out of it is to accept (...) that the relevance-theoretic comprehension procedure ap- plies to certain non-ostensive stimuli, contrary to what is generally claimed within RT. In particular, I will argue that relevance theorists should accept that (ceteris paribus) non- ostensive emotional expressions in interactions guarantee a presumption of relevance such that they are interpreted through the relevance-theoretic comprehension procedure. This leads me to propose what I call 'the expressive principle of relevance'. (shrink)

Ostension is bodily movement that manifests our engagement with things, whether we wish it to or not. Gestures, glances, facial expressions: all betray our interest in something. Ostension enables our first word learning, providing infants with a prelinguistic way to grasp the meaning of words. Ostension is philosophically puzzling; it cuts across domains seemingly unbridgeable -- public--private, inner--outer, mind--body. In this book, Chad Engelland offers a philosophical investigation of ostension and its role in word learning by infants. Engelland discusses ostension (...) (distinguishing it from ostensive definition) in contemporary philosophy, examining accounts by Quine, Davidson, and Gadamer, and he explores relevant empirical findings in psychology, evolutionary anthropology, and neuroscience. He offers original studies of four representative historical thinkers whose work enriches the understanding of ostension: Wittgenstein, Merleau-Ponty, Augustine, and Aristotle. And, building on these philosophical and empirical foundations, Engelland offers a meticulous analysis of the philosophical issues raised by ostension. He examines the phenomenological problem of whether embodied intentions are manifest or inferred; the problem of what concept of mind allows ostensive cues to be intersubjectively available; the epistemological problem of how ostensive cues, notoriously ambiguous, can be correctly understood; and the metaphysical problem of the ultimate status of the key terms in his argument: animate movement, language, and mind. Finally, he argues for the centrality of manifestation in philosophy. Taking ostension seriously, he proposes, has far-reaching implications for thinking about language and the practice of philosophy. (shrink)

Brian Skyrms offers a fascinating demonstration of how fundamental signals are to our world. He uses various scientific tools to investigate how meaning and communication develop. Signals operate in networks of senders and receivers at all levels of life, transmitting and processing information. That is how humans and animals think and interact.

Introspection is a fundamental part of our mental lives. Nevertheless, its reliability and its underlying cognitive architecture have been widely disputed. Here, I propose a principled way to model introspection. By using time-tested principles from signal detection theory (SDT) and extrapolating them from perception to introspection, I offer a new framework for an introspective signal detection theory (iSDT). In SDT, the reliability of perceptual judgments is a function of the strength of an internal perceptual response (signal- to-noise ratio) which is, (...) to a large extent, driven by the intensity of the stimulus. In parallel to perception, iSDT models the reliability of introspective judgments as a function of the strength of an internal introspective response (signal-to-noise ratio) which is, to a large extent, driven by the intensity of conscious experiences. Thus, by modelling introspection after perception, iSDT can calibrate introspection’s reliability across a whole range of contexts. iSDT offers a novel, illuminating way of thinking about introspection and the cognitive processes that support it.

Although the definition of ‘signal’ has been controversial for some time within the life sciences, current approaches seem to be converging toward a common analysis. This powerful framework can satisfactorily accommodate many cases of signaling and captures some of its main features. This paper argues, however, that there is a central feature of signals that so far has been largely overlooked: its special causal role. More precisely, I argue that a distinctive feature of signals is that they are (...) minimal causes. I explain this notion, suggest some strategies for identifying its instances and defend its relevance by means of conceptual and empirical considerations. (shrink)

In the first part of my paper I discuss eight arguments in favour of the theory-dependence of observation: realistic content, guidance function of theories, perception as cognitive construction, expectation-dependence of perception, theory-dependence of scientific data, continuity between observational and theoretical concepts, language-dependence, and meaning holism. I argue that although these arguments make correct points, they do not exclude the existence of observations that are weakly theory-neutral in the sense that they don’t depend on acquired background knowledge. In the second part (...) I suggest an experimental method, the method of ostensive learning experiments, by which the degree of theory- and language-independence of a concept can be tested. (shrink)

This paper addresses two problems concerning the deferred ostension of extinct and fictive kinds. First, the sampled item, the fossil or the depiction, is not a sample of the referent. Nonetheless, the retained characteristic shape, understood via analogy with living creatures, enables the reference to be fixed. Second, though both extinct and fictive kinds are targets of deferred ostension, there is an important difference in the sample. Fossilization is a natural causal process that makes fossils to be reflections of their (...) originals. As reflections, fossils embed their referents in the primary existential world of perceived things. Images of artificial kinds, by contrast, leave their referents in the secondary existential world of mere appearance. In this way, the paper widens the scope of the Kripke-Putnam account of ostension for naming kinds by drawing on Quine’s concept of deferred ostension for absent referents. (shrink)

Together, the code and inferential models of communication are often thought to range over all cases of communication. However, their prevailing versions seem unable to fully explain what I call underdeterminacy without ostension. The latter is constituted by communication where stimuli that are not (nor appear to be) produced with communicative or informative intentions nevertheless communicate information underdetermined by the relevant codes. Though the prevailing accounts of communication cannot fully explain how communication works in such cases, I suggest that some (...) version of the inferential model can—if we allow it to extend to non‐ostensive, non‐intentional behaviors.

It is sometimes argued that while human gestures are produced ostensively and intentionally, great ape gestures are produced only intentionally. If true, this would make the psychological mechanisms underlying the different species’ communication fundamentally different, and ascriptions of meaning to chimpanzee gestures would be inappropriate. While the existence of different underlying mechanisms cannot be ruled out, in fact claims about difference are driven less by empirical data than by contested assumptions about the nature of ostensive communication. On some accounts, (...) there are no reasons to doubt that great ape gestural communication is ostensive. If these accounts are correct, attributions of meaning to chimpanzee gestures would be justified. (shrink)

This paper proposes a new theory of the nature of hypocritical blame and why it is objectionable, arguing that hypocritical blame is a form of dishonest signaling. Blaming provides very important benefits: through its ability to signal our commitments to norms and unwillingness to tolerate norm violations, it greatly contributes to valuable norm-following. Hypocritical blamers, however, are insufficiently committed to the norms or values they blame others for violating. As allowing their blame to pass unchecked threatens the signaling system, our (...) strong interest in maintaining valuable norm-following by tracking who has what commitments justifies objecting to hypocritical blame. This theory has a number of strengths over competing accounts: it delivers intuitive verdicts about when blame is objectionable across a range of cases, it is a naturalistic explanation, it is consistent with a leading theory of the nature of blame, it explains why hypocritical pronouncements that don’t feature blame are similiarly objectionable, it does not rely on contentious analyses of the nature of ‘standing’, and it preserves the common intuition that hypocrites are in some way dishonest.

Several theories link consciousness to complex cortical dynamics, as suggested by comparison of brain signal diversity between conscious states and states where consciousness is lost or reduced. In particular, Lempel-Ziv complexity, amplitude coalition entropy and synchrony coalition entropy distinguish wakefulness and REM sleep from deep sleep and anesthesia, and are elevated in psychedelic states, reported to increase the range and vividness of conscious contents. Some studies have even found correlations between complexity measures and facets of self-reported experience. As suggested by (...) integrated information theory and the entropic brain hypothesis, measures of differentiation and signal diversity may therefore be measurable correlates of consciousness and phenomenological richness. Inspired by these ideas, we tested three hypotheses about EEG signal diversity related to sleep and dreaming. First, diversity should decrease with successively deeper stages of non-REM sleep. Second, signal diversity within the same sleep stage should be higher for periods of dreaming vs. non-dreaming. Third, specific aspects of dream contents should correlate with signal diversity in corresponding cortical regions. We employed a repeated awakening paradigm in sleep deprived healthy volunteers, with immediate dream report and rating of dream content along a thought-perceptual axis, from exclusively thought-like to exclusively perceptual. Generalized linear mixed models were used to assess how signal diversity varied with sleep stage, dreaming and thought-perceptual rating. Signal diversity decreased with sleep depth, but was not significantly different between dreaming and non-dreaming, even though there was a significant positive correlation between Lempel-Ziv complexity of EEG recorded over the posterior cortex and thought-perceptual ratings of dream contents.

Defends a version of the Davidsonian Demonstrative Theory of quotation against proponents of the Fregean Identity Theory.

This paper defends a version of Davidson’s demonstrative theory of quotation and against against the Fregean identity theory (IT henceforth) as articulated and defended by Corey Washington (1992). On the Fregean view, when an expression is referred to by means of quotation the quoted material itself is a linguistic referring expression. Quotation-marks are not needed; when they are used, they serve to make clearer the shift in syntactic and semantic properties effected on the quoted material by its occupying that linguistic (...) context: whatever its usual syntactic function, the quoted material functions as a singular term; whatever its usual semantic function, in that linguistic environment the quoted material refers to itself. On DT, in contrast, quotation-marks themselves are the linguistic bearers of reference, functioning like a demonstrative; the quoted material merely plays the role of a demonstratum. In the version I argue for the referent is obtained through some contextually suggested relation; in the default case the relation will be: … instantiates the linguistic type __, but there are other possibilities. In this way, the view can deal with the fact that we do not merely refer with quotations to expression-types, but also to other entities related in some way to the relevant token we use: features exhibited by the token distinct from those constituting its linguistic type, features exhibited by other tokens of the same type but not by the one actually used (as when, by using a graphic token, we refer to its phonetic type), or even other related tokens.

One might think that if the majority of virtue signallers judge that a proposition is true, then there is significant evidence for the truth of that proposition. Given the Condorcet Jury Theorem, individual virtue signallers need not be very reliable for the majority judgment to be very likely to be correct. Thus, even people who are skeptical of the judgments of individual virtue signallers should think that if a majority of them judge that a proposition is true, then that provides (...) significant evidence that the proposition is true. We argue that this is mistaken. Various empirical studies converge on the following point: humans are very conformist in the contexts in which virtue signalling occurs. And stereotypical virtue signallers are even more conformist in such contexts. So we should be skeptical of the claim that virtue signallers are sufficiently independent for the Condorcet Jury Theorem to apply. We do not seek to decisively rule out the relevant application of the Condorcet Jury Theorem. But we do show that careful consideration of the available evidence should make us very skeptical of that application. Consequently, a defense of virtue signalling would need to engage with these findings and show that despite our strong tendencies for conformism, our judgements are sufficiently independent for the Condorcet Jury Theorem to apply. This suggests new directions for the debate about the epistemology of virtue signalling. (shrink)

Abstract. The strong similarity between the use of ostension and that of a simple demonstrative to predicate something of an object seems to conflict with equally strong intuitions according to which, while “this” does usually refer to an object, the gesture of holding an object in your hand and showing it to an audience does not refer to the demonstrated object. This paper argues that the problem is authentic and provides a solution to it. In doing so, a more general (...) thought is given support by the approach used. Namely, the thought that our abilities to directly refer to things require some basic referential abilities exhibited in ostension and the use of demonstratives which, in their turn, rest upon our abilities to cooperate in performing non-communicative actions on our environment. Several concepts introduced in order to solve the initial problem can be used to articulate this thought in more detail. (shrink)

The accusation of virtue signalling is typically understood as a serious charge. Those accused usually respond by attempting to show that they are doing no such thing. In this paper, I argue that we ought to embrace the charge, rather than angrily reject it. I argue that this response can draw support from cognitive science, on the one hand, and from social epistemology on the other. I claim that we may appropriately concede that what we are doing is virtue signalling, (...) because virtue signalling is morally appropriate. It neither expresses vices, nor is hypocritical, nor does it degrade the quality of public moral discourse. Signalling our commitment to norms is a central and justifiable function of moral discourse, and the same signals provide evidence that is appropriately taken into account in forming moral beliefs.
