The rubber hand paradigm is used to create the illusion of self-touch, by having the participant administer stimulation to a prosthetic hand while the Examiner, with an identical stimulus , administers stimulation to the participant’s hand. With synchronous stimulation, participants experience the compelling illusion that they are touching their own hand. In the current study, the robustness of this illusion was assessed using incongruent stimuli. The participant used the index finger of the right hand to administer stimulation to a prosthetic hand while the Examiner used a paintbrush to administer stimulation to the participant’s left hand. The results indicate that this violation of tactile expectations does not diminish the illusion of self-touch. Participants experienced the illusion despite the use of incongruent stimuli, both when vision was precluded and when visual feedback provided clear evidence of the tactile mismatch

Many philosophers and psychologists argue that normal adult human beings possess a primitive or 'folk' psychological theory. Recently, however, this theory has come under challenge from the simulation alternative. This alternative view says that human bings are able to predict and explain each others' actions by using the resources of their own minds to simuate the psychological etiology of the actions of others. The thirteen essays in this volume present the foundations of theory of mind debate, and are accompanied by an extensive introduction.

He then argues that (1), (2) and (3) constitute an inconsistent triad as follows (1991, p. 15): Suppose (1) that Oscar knows a priori that he is thinking that water is wet. Then by (2), Oscar can simply deduce E, using premisses that are knowable a priori, including the premiss that he is thinking that water is wet. Since Oscar can deduce E from premisses that are knowable a priori, Oscar can know E itself a priori. But this contradicts (3), the assumption that E cannot be known a priori. Hence (1), (2), and (3) are inconsistent. McKinsey’s conclusion is that ‘anti-individualism is inconsistent with privileged access’ (ibid.)

Proponents of fetal rights argue that, from the moment of conception, a fetus has significant human rights. There are degrees of opinion, however, about the scope of those rights, with some arguing that, in certain circumstances, such as where the conception is the result of rape, the mother's rights predominate. Others argue that the fetus' rights are absolute and should override the woman's right to life and health so that pregnancies cannot be terminated, even to save women's lives. Various countries explicitly or implicitly recognise the status of the fetus as a separate person with varying degrees of rights. For example, the Irish Constitution recognises the ‘right to life of the unborn’ and the 2004 US Unborn Victims of Violence Act views violence against a pregnant woman as a crime against two people, one of whom is the child in utero. The 1969 American Convention on Human Rights has been signed by most Latin American countries and recognises full human rights as applying from conception. In the UK, the fetus has no legal rights but it is widely agreed that the closer a fetus is to being capable of independent existence outside the womb, the greater the moral obligations owed to it. This is reflected in the abortion law only permitting termination of a pregnancy at the later stages in restricted circumstances.In Brazil, the issue of fetal rights was highlighted in May 2010 when a Bill was put forward which aimed to give the fetus priority in law and to make illegal any act or omission that could have a negative impact on it. The bill proposes that the family, society and the …

In his paper ‘Scmantic Theory and Tacit Knowlcdgc’, Gareth Evans uscs a familiar kind of cxamplc in ordcr to render vivid his account of tacit knowledge. We arc to consider a finite language, with just one hundrcd scntcnccs. Each scntcncc is made up of a subjcct (a name) and a prcdicatc. The names are ‘a’, ‘b’,..., T. The prcdicatcs arc ‘F’, ‘G’,..., ‘O’. Thc scntcnccs have meanings which dcpcnd in a systematic way upon their construction. Thus, all scntcnccs containing ‘a’ mean something about john; all scntcnccs containing ‘b’ mean something about Harry; all scntcnccs containing ‘F’ mean something about being bald; all scntcnccs containing ‘G’ mean something about being happy; and so 011. For this vcry simple language L, wc arc to consider various semantic theories. We could consider thcorics whosc dclivcranccs about wholc scntcnccs are of..

In this paper, I shall defend externalism for the contents of perceptual experience. A perceptual experience has representational properties; it presents the world as being a certain way. A visual experience, for example, might present the world to a subject as containing a surface with a certain shape, lying at a certain distance, in a certain direction; perhaps a square with sides about 30 cm, lying about one metre in front of the subject, in a direction about 20 degrees to the left of straight ahead.

The work reported in this paper investigated the putative functional dependence of pragmatic language skills on general mind‐reading capacity by testing theory‐of‐mind abilities and understanding of non‐literal speech in patients with schizophrenia and in healthy controls. Patients showed difficulties with inferring mental states on a false‐belief picture‐sequencing task and with understanding metaphors and irony on a story‐comprehension task. These difficulties were independent of low verbal IQ and a more generalised problem inhibiting prepotent information. Understanding of metaphors and understanding of irony made significant and independent contributions to discriminating patients from controls, suggesting that metaphor and irony make distinct pragmatic demands.

The question posed by Dunn and Kirsner (D&K) is an instance of a more general one: What can we infer from data? One answer, if we are talking about logically valid deductive inference, is that we cannot infer theories from data. A theory is supposed to explain the data and so cannot be a mere summary of the data to be explained. The truth of an explanatory theory goes beyond the data and so is never logically guaranteed by the data. This is not just a point about cognitive neuropsychology, or even about psychology in general. It is a familiar point about all science.

Force-feeding of detainees at Guantánamo BayIn April, the US Department of Defense reportedly sent 40 additional military medical personnel, including doctors and nurses, to the Guantánamo Bay Naval Base to carry out the force-feeding of detainees on hunger strike.1 By the end of June, up to 104 of the remaining 166 individuals held in US military detention at Guantánamo were refusing food. The protest against conditions at the base, and the fate of those being held there—including those already cleared for transfer or release—began in February 2013. In June, it was reported that as many as 44 of the hunger strikers were being force-fed by military medical teams.2The response by the US authorities to the hunger strike prompted expressions of outrage from the international medical community.3,4 In April, the American Medical Association wrote to the US secretary of defense, insisting that ‘forced feeding of [competent] detainees violates core ethical values of the medical profession.’5 Adding the voice of the profession in the UK to these calls, at its annual conference in June, the British Medical Association condemned the participation of doctors and nurses in the force-feeding, calling on governments worldwide to ensure that all prisoners have access to confidential, independent medical treatment, and supporting any clinician who challenged cruel, inhuman or degrading treatment. Also in June, the BMA Chairman wrote to President Obama and US secretary of defense, Hagel, urging them to immediately suspend medical involvement in force-feeding at Guantánamo, and to institute an urgent inquiry into how the current situation was allowed to develop.Force-feeding mentally competent adults who are refusing food is a clear violation of medical ethics and is unjustifiable, as articulated by the World Medical Association's Declaration of Malta.6 Doctors with dual loyalties, including military doctors, are bound by the same …

In this paper, I define tacit knowledge as a kind of causal-explanatory structure, mirroring the derivational structure in the theory that is tacitly known. On this definition, tacit knowledge does not have to be explicitly represented. I then take the notion of a modular theory, and project the idea of modularity to several different levels of description: in particular, to the processing level and the neurophysiological level. The fundamental description of a connectionist network lies at a level between the processing level and the physiological level. At this level, connectionism involves a characteristic departure from modularity, and a correlative absence of syntactic structure. This is linked to the fact that tacit knowledge descriptions of networks are only approximately true. A consequence is that strict causal systematicity in cognitive processes poses a problem for the connectionist programme.

A simple experimental paradigm creates the powerful illusion that one is touching one’s own hand even when the two hands are separated by 15 cm. The participant uses her right hand to administer stimulation to a prosthetic hand while the Examiner provides identical stimulation to the participant’s receptive left hand. Change in felt position of the receptive hand toward the prosthetic hand has previously led to the interpretation that the participant experiences self-touch at the location of the prosthetic hand, and experiences a sense of ownership of the prosthetic hand. Our results argue against this interpretation. We assessed change in felt position of the participant’s receptive hand but we also assessed change in felt position of the participant’s administering hand. Change in felt position of the administering hand was significantly greater than change in felt position of the receptive hand. Implications for theories of ownership are discussed
