When we hear another person laugh or scream, can we tell the kind of situation they are in – for example, whether they are playing or fighting? Nonverbal expressions are theorised to vary systematically across behavioural contexts. Perceivers might be sensitive to these putative systematic mappings and thereby correctly infer contexts from others’ vocalisations. Here, in two pre-registered experiments, we test the prediction that listeners can accurately deduce production contexts (e.g. being tickled, discovering threat) from spontaneous nonverbal vocalisations, like sighs (...) and grunts. In Experiment 1, listeners (total n = 3120) matched 200 nonverbal vocalisations to one of 10 contexts using yes/no response options. Using signal detection analysis, we show that listeners were accurate at matching vocalisations to nine of the contexts. In Experiment 2, listeners (n = 337) categorised the production contexts by selecting from 10 response options in a forced-choice task. By analysing unbiased hit rates, we show that participants categorised all 10 contexts at better-than-chance levels. Together, these results demonstrate that perceivers can infer contexts from nonverbal vocalisations at rates that exceed that of random selection, suggesting that listeners are sensitive to systematic mappings between acoustic structures in vocalisations and behavioural contexts.

Odd and memorable examples are a distinctive feature of Charles Travis's work: cases involving squash balls, soot-covered kettles, walls that emit poison gas, faces turning puce, ties made of freshly cooked linguine, and people grunting when punched in the solar plexus all figure in his arguments. One of Travis's examples, involving a pair of situations in which the leaves of a Japanese maple tree are painted green, has even spawned its own literature consisting of attempts to explain the context sensitivity (...) of color adjectives ("green", e.g.). For Travis, these examples play a central role in his arguments for occasion-sensitivity, which he takes to be a pervasive feature of how we understand natural language. But how, exactly, do these examples work? My aims in this paper are to put Travis’s examples under the microscope, using recent experimental studies of Travis-style cases to raise worries about aspects of the way Travis's cases are informally presented, but then show how his examples can be redesigned to respond to these doubts.

This article analyzes the scientific debate surrounding the appropriateness of pharmacological interventions aimed at increasing female desire. It has three objectives: (1) to outline the nonepistemic values that underlie scientific concepts of desire; (2) to conduct an analysis of scientific misuses when justifying a drive-based model of desire and pharmacological intervention; and (3) to show how in this and similar cases of vague constructs we can demonstrate the role of nonepistemic values and assess their influence.

Much of modern ethics is built around the idea that we should respect one another’s autonomy. Here, “we” are typically imagined to be adult human beings of sound mind, where the soundness of our mind is measured against what we take to be the typical mental capacities of a neurodevelopmentally “normal” person—perhaps in their mid-thirties or forties. When deciding about what constitutes ethical sex, for example, our dominant models hold that ethical sex is whatever is consented to, while a lack (...) of consent makes sex wrong.1 Consent, in turn, is analysed in terms of autonomous decision-making: a “yes” or “no” that reflects the free and informed will of our idealised, sound-minded adult. Whether such models provide adequate normative guidance for ethical, much less good, sex between neurotypical human adults is an open question.2 3 When it comes to the ethics of sexual activity between humans and non-humans—robots, say—or between humans who don’t fit the rational stereotype, we hardly know where to begin.4–7 It is therefore heartening to see a number of papers in this issue tackling the difficult question how to respectfully facilitate or respond to the needs, desires, and decisions of people with different kinds or degrees of autonomy.8 For example, Sumytra Menon and colleagues9 explicitly discuss the notion of “borderline capacity” and argue, in the medical domain, for shared and supportive decision-making practices to “foster the autonomy of patients with compromised mental capacity while being mindful of the need to safeguard their well-being.” Touching on a similar theme, Zahra Ladan 10 asks how we should conceive of liberty in the case of persons with certain inborn physical or mental limitations. Might it sometimes be necessary to …. (shrink)

Nondirectiveness is widely regarded as an important principle of genetic counseling. However, numerous studies have indicated that the use of this principle and its content itself are subject to controversies. The present study aimed to verify how the nondirectiveness principle is defined by Polish geneticists, the extent to which it is considered the main principle in clinical practice, and the situations in which geneticists see the positive value of the directive action. Using quantitative and qualitative methods, the study compared the (...) abstract declarations of the directiveness validity and the scope of this principle with the declaration of action in situations close to reality (case scenarios). The results showed that the high rank assigned to the nondirectiveness principle does not translate into the conviction about the absolute obligation to use it in clinical practice. Polish geneticists are inclined to restrict the scope of patients’ choices when these are outside of their definition of medical standard. Strong medical paternalism manifests itself particularly in invasive prenatal diagnostics, where geneticists play the role of gatekeepers. In this study, we offer hypotheses about the sources of these attitudes by analyzing the current cultural and legal context of Poland. (shrink)

A significant proportion of conservationists' work is directed towards efforts to save disappearing species. This relies upon the belief that species extinction is undesirable. When justifications are offered for this belief, they very often rest upon the assumption that extinction brought about by humans is different in kind from other forms of extinction. This paper examines this assumption and reveals that there is indeed good reason to suppose current anthropogenic extinctions to be different in kind from extinctions brought about at (...) other times or by other factors. Having considered – and rejected – quantity and rate of extinction as useful distinguishing factors, four alternative arguments are offered, each identifying a way in which anthropogenic extinction is significantly different from other forms of extinction, even mass extinction: (1) Humans are a different kind of natural cause from other causes of extinction; (2) Extinctions brought about by humans are uniquely persistent; (3) Anthropogenic extinctions are effectively random whereas past mass extinctions are rule-bound; (4) The impact of the current anthropogenic extinction event differs from the impact of other extinction events of the past, such that future recovery may not follow past patterns. Together, these four arguments suggest that the present-day extinction event brought about by humans may be unprecedented and that we cannot clearly extrapolate from past to present recovery from extinctions. Although insufficient as justification for the claim that present-day extinctions are undesirable, the arguments provide some ammunition for conservationists' conviction that species extinction – in which humans play an accelerating role – ought to be prevented.

This paper is a study of the mental environment of the Newtonian conception of attraction in the case of George Cheyne, M.D. , physician of the early 18th century and author of a number of popular medical works. It traces the growth of his notions of a spiritual attraction between God and his creatures and between the creatures themselves, and the relation of these ideas both to his use of the Newtonian model of short-range attraction, and to his conception of (...) the creatures as reflections of the divine essence. The paper contends that the development of these aspects of Cheyne's thought harmonizes with the changing pattern of his life, and that this harmony is expressed by his general technique of reasoning by analogy between the various spheres of experience.
