In cognitive science, there is a tacit norm that phenomena such as cultural variation or synaesthesia are worthy examples of cognitive diversity that contribute to a better understanding of cognition, but that other forms of cognitive diversity (e.g., autism, attention deficit hyperactivity disorder/ADHD, and dyslexia) are primarily interesting only as examples of deficit, dysfunction, or impairment. This status quo is dehumanizing and holds back much-needed research. In contrast, the neurodiversity paradigm argues that such experiences are not necessarily deficits but rather (...) are natural reflections of biodiversity. Here, we propose that neurodiversity is an important topic for future research in cognitive science. We discuss why cognitive science has thus far failed to engage with neurodiversity, why this gap presents both ethical and scientific challenges for the field, and, crucially, why cognitive science will produce better theories of human cognition if the field engages with neurodiversity in the same way that it values other forms of cognitive diversity. Doing so will not only empower marginalized researchers but will also present an opportunity for cognitive science to benefit from the unique contributions of neurodivergent researchers and communities.

Nietzsche’s naturalism is a well-rehearsed theme. The latter has become somewhat of an orthodoxy in Anglo-American scholarship, and it is often connected to the rediscovery of Nietzsche’s ethical thought among analytic philosophers. Philosophical naturalism, of course, can mean many different things, and Nietzsche’s rhetoric, his polemical stance and tendency toward hyperbole, are not exactly hallmarks of a philosophical naturalism that situates itself in close proximity to the methods and methodologies of the natural sciences. On the other hand, it is difficult (...) to deny that much of Nietzsche’s work—perhaps even from the early essay on “Truth and Lying in an Extra-moral Sense” onward—speaks to a tradition.. (shrink)

Thomas Elsaesser claims the late Haneke as a director of ‘mind-game’ films, but his diagnosis of the appeal of such films fails to account for The White Ribbon . In this paper, I draw on the theory of radical interpretation developed by American philosopher Donald Davidson to uncover the film’s power. I argue that the focus on charity in Davidson’s account of the conditions under which an interpreter is able to find a foreign community intelligible illuminates the exquisite discomfort the (...) spectator experiences as she begins to understand the disturbed community that the film portrays. In addition, the film exposes that Davidson’s transcendental argument that language is a condition of mindedness ought to be extended along emotional and moral dimensions. We should not only hold that every rational mind is a language-user, but that every rational mind is an appropriate language-user, so as to account for minds that have true, justified beliefs but which are, nevertheless, disturbed.

We hypothesize that black women experience accelerated biological aging in response to repeated or prolonged adaptation to subjective and objective stressors. Drawing on stress physiology and ethnographic, social science, and public health literature, we lay out the rationale for this hypothesis. We also perform a first population-based test of its plausibility, focusing on telomere length, a biomeasure of aging that may be shortened by stressors. Analyzing data from the Study of Women’s Health Across the Nation (SWAN), we estimate that at (...) ages 49–55, black women are 7.5 years biologically “older” than white women. Indicators of perceived stress and poverty account for 27% of this difference. Data limitations preclude assessing objective stressors and also result in imprecise estimates, limiting our ability to draw firm inferences. Further investigation of black-white differences in telomere length using large-population-based samples of broad age range and with detailed measures of environmental stressors is merited. (shrink)

The vestibular system encodes motion and orientation of the head in space and is essential for negotiating in and interacting with the world. Recently, random waveform electric vestibular stimulation has become an increasingly common means of probing the vestibular system. However, many of the methods used to analyze the behavioral response to this type of stimulation assume a linear relationship between frequencies in the stimulus and its associated response. Here we examine this stimulus-response frequency linearity to determine the validity of (...) this assumption. Forty-five university-aged subjects stood on a force-plate for 4 min while receiving vestibular stimulation. To determine the linearity of the stimulus-response relationship we calculated the cross-frequency power coupling between a 0 and 25 Hz bandwidth limited white noise stimulus and induced postural responses, as measured using the horizontal forces acting at the feet. Ultimately, we found that, on average, the postural response to a random stimulus is linear across stimulation frequencies. This result supports the use of analysis methods that depend on the assumption of stimulus-response frequency linearity, such as coherence and gain, which are commonly used to analyze the body’s response to random waveform electric stimuli.

Many traditional Mahayana, and modern Tibetan, Buddhist texts relate meditation attainment to psychic ability. This teaching served as the hypothesis—that more advanced meditators would choose a psi target correctly, significantly more often than beginners. A basic free-response design was used in which a computer programme (PreCOG) chose a target picture at random from a 4-picture set. There were 25 sets, all pictures of Tibet. PreCOG guided the participants through the procedure, in which they aimed to become aware of the target. (...) 18 participants, Tibetan monks, nuns and Western Buddhist meditators, completed 8 sessions each. Half the sessions used a clairvoyance, and half a precognition, protocol. Age and years of meditation practice correlated significantly with the psi scores (Pearson r = 0.52, p < 0.05). This suggests that, as one practices meditation, psychic awareness begins to manifest more reliably. This result was confounded by a non-significant psi-missing trend. There was no significant difference between the clairvoyance and precognition trials (t-diff (142) = 0.800). There was, however, significant psi-missing from the group of Rinpoches (t = -2.09, 2tail p < 0.05). The three participants who scored most strongly in the psi-missing direction all reported childhood memories of previous lives as monks in Tibet. Keywords: psychic awareness—Tibetan Buddhists—meditation. (shrink)

Since the time of Brunck there has been a more or less general acquiescence in his substitution of πνθμεθα for πνθομεθα, inasmuch as there is no obvious reason to be alleged in support of the optative. Campbell, it is true, found the optative more in accord with the feeling of the blind and weary Oedipus; but who will listen to this nowadays? Therefore it is the more surprising that Radermacher should retain the optative as expressing the eager wish to attain (...) the goal, basing himself on J. M. Stahl's Syntax of the Greek Verb, p. 482. For Stahl, who admits the existence of certain exceptional instances to be justified in this sense, expressly excludes from the category this passage as well as El. 57 and 760, and seeks to limit the scope of his pronouncement to the writings of Aristophanes, Xenophon and the Orators—a curious combination.

In this paper, we develop the notion of a natural convention, and illustrate its usefulness in a detailed examination of indirect requests in English. Our treatment of convention is grounded in Lewis’s seminal account; we do not here redefine convention, but rather explore the space of possibilities within Lewis’s definition, highlighting certain types of variation that Lewis de-emphasized. Applied to the case of indirect requests, which we view through a Searlean lens, the notion of natural convention allows us to give (...) a nuanced answer to the question: Are indirect requests conventional? In conclusion, we reflect on the consequences of our view for the understanding of the semantics/pragmatics divide. (shrink)

In seeking to explain the evolution of social cooperation, many scholars are using increasingly complex game-theoretic models. These complexities often model readily observable features of human and animal populations. In the case of previous games analyzed in the literature, these modifications have had radical effects on the stability and efficiency properties of the models. We will analyze the effect of adding spatial structure to two communication games: the Lewis Sender-Receiver game and a modified Stag Hunt game. For the Stag Hunt, (...) we find that the results depart strikingly from previous models. In all cases, the departures increase the explanatory value of the models for social phenomena. (shrink)

Recent research into the evolution of higher cognition has piqued an interest in the effect of natural selection on the ability of creatures to respond to their environment (behavioral plasticity). It is believed that environmental variation is required for plasticity to evolve in cases where the ability to be plastic is costly. We investigate one form of environmental variation: frequency dependent selection. Using tools in game theory, we investigate a few models of plasticity and outline the cases where selection would (...) be expected to maintain it. Ultimately we conclude that frequency dependent selection is likely insufficient to maintain plasticity given reasonable assumptions about its costs. This result is very similar to one aspect of the well-discussed Baldwin effect, where plasticity is first selected for and then later selected against. We show how in these models one would expect plasticity to grow in the population and then be later reduced. Ultimately we conclude that if one is to account for the evolution of behavioral plasticity in this way, one must appeal to a very particular sort of external environmental variation. (shrink)

The introduction of the Diagnostic and Statistical Manual of Mental Disorders in May 2013 is being hailed as the biggest event in psychiatry in the last 10 years. In this paper I examine three important issues that arise from the new manual: Expanding nosology: Psychiatry has again broadened its nosology to include human experiences not previously under its purview. Consequence-based ethical concerns about this expansion are addressed, along with conceptual concerns about a confusion of "construct validity" and "conceptual validity" and (...) a failure to distinguish between "disorder" and "nondisordered conditions for which we help people." The role of claims about societal impact in changes in nosology: Several changes in the DSM-5 involved claims about societal impact in their rationales. This is due in part to a new online open comment period during DSM development. Examples include advancement of science, greater access to treatment, greater public awareness of condition, loss of identify or harm to those with removed disorders, stigmatization, offensiveness, etc. I identify and evaluate four importantly distinct ways in which claims about societal impact might operate in DSM development. Categorisation nosology to spectrum nosology: The move to "degrees of severity" of mental disorders, a major change for DSM-5, raises concerns about conceptual clarity and uniformity concerning what it means to have a severe form of a disorder, and ethical concerns about communication.

As part of a larger research study, we present model language for disclosing financial interests in clinical research to potential research participants, and we describe the empirical basis and theoretical assumptions used in developing the language. The empirical process for creating appropriate disclosure language resulted in a generic disclosure statement for cases in which no risk to participants’ welfare or the scientific integrity of the research is expected, and nine more specific disclosure statements for cases in which some risk is (...) expected. The disclosure statements are not meant to be canonical, but were instead designed to reflect the typical situations in which disclosure of financial interest might be considered by an institutional review board or conflict of interest committee. Individual institutions could modify key phrases to suit their purposes, and others could use the language in future empirical work on informed consent to better refine the options for disclosing financial interests in clinical research.
