When an experimenter uses the experimental method to investigate the effects of the experimenter's expectancy it may be that this research, too, is affected by his expectancy and thus there is an expectancy paradox. To the extent that the experimenter expectancy effect accounts for the variation in the dependent variable and is general, that is to say, universal in psychological research, the expectancy paradox is ineluctable. However, an analysis of the research reviews extant in this area yields the conclusion that (...) expectancy effects are neither inexorable nor highly general in psychological research and this provides the basis for its extrication from the expectancy paradox.

Despite the by now historical tendency to demarcate scientific epistemology sharply from virtually all others, especially theological “epistemology,” it has recently been recognized that both enterprises share a great deal in common, at least as far as the epistemology of discovery is implicated. Such a claim is founded upon a psychological analysis of figuration, where, it is argued, metaphor plays a crucial role in the mediation of discovery, in the domains of science and religion alike. Thus, although the conventionally conceived (...) scientific method is crucial to the enterprise, primacy must nonetheless be accorded to discovery, which drives virtually all disciplines. (shrink)

The logical consistency of a collection of assertions about events can be viewed as a special case of coherent probability assessments in the sense of de Finetti.

Objective The UK Human Papillomavirus (HPV) vaccine programme commenced in the autumn of 2008 for year 8 (age 12–13 years) schoolgirls. We examine whether the vaccine should be given when there is a difference of opinion between daughters and parents or guardians. Design Qualitative study using semi-structured interviews. Participants A sample of 25 stakeholders: 14 professionals involved in the development of the HPV vaccination programme and 11 professionals involved in its implementation. Results Overriding the parents' wishes was perceived as problematic (...) and could damage the relationship between school and parents. A number of practical problems were raised in relation to establishing whether parents were genuinely against their daughter receiving the vaccine. Although many respondents recognised that the Gillick guidelines were relevant in establishing whether a girl could provide consent herself, they still felt that there were significant problems in establishing whether girls could be assessed as Gillick competent. In some areas school nurses had been advised not to give the vaccine in the absence of parental consent. None of the respondents suggested that a girl should be vaccinated against her consent even if her parents wanted her to have the vaccine. Conclusions While the Gillick guidelines provide a legal framework to help professionals make judgements about adolescents consenting to medical treatment, in practice there appears to be variable and confused interpretation of this guidance. Improved legal structures, management procedures and professional advice are needed to support those who are assessing competence and establishing consent to vaccinate adolescents in a school setting.

David Hume's Treatise of Human Nature, composed before the author was twenty-eight years old, was published in 1739 and 1740. In revising the late L.A. Selby-Bigge's edition of Hume's Treatise Professor Nidditch corrected verbal errors and took account of Hume's manuscript amendments. He also supplied the text of theof the Treatise following the original 1740 edition and provided an apparatus of variant readings.

David Hume's Treatise of Human Nature, was composed before the author was twenty-six years old, was published in 1739 and 1740. Its importance was not generally recognised at the time. Hume, attributing the failure of his Treatise to the manner of its writing rather than the matter is contained, cast the first part of that work anew in the Enquiry concerning Human Understanding, and afterwards continued the same process in the second work contained in this volume, the Enquiry concerning the (...) Principles of Morals. (shrink)

Subjective feelings of familiarity associated with a stimulus tend to be strongest when specific information about the previous encounter with the stimulus is difficult to retrieve . Recognizing: The judgment of previous occurrence. Psychological Review, 87, 252–271.]). When a stimulus has been encountered previously and the circumstances of the encounter cannot be recollected, additional cognitive resources may be directed toward recollection processes; this resource allocation is accompanied by autonomic arousal [Dawson, M. E., Filion, D. L., & Schell, A. M. . (...) Is elicitation of the autonomic orienting response associated with allocation of processing resources?. Psychophysiology, 26, 560–572]. One easily measurable index of autonomic arousal is the skin conductance response . In the present study, participants studied lists of words and then gave recognition ratings to briefly displayed and masked studied and nonstudied test words while their SCRs were monitored. Results revealed a relationship between recognition ratings and the temporal characteristics of the SCR, supporting the idea that feelings of familiarity are indeed “feelings” in that they stem from autonomic arousal associated with cognitive resource allocation.

Gregory S. Kavka was a prominent and influential figure in contemporary moral and political philosophy. The essays in this volume are concerned with fundamental issues of rational commitment and social justice to which Kavka devoted his work as a philosopher. The essays take Kavka's work as a point of departure and seek to advance the respective debates. The topics include: the relationship between intention and moral action as part of which Kavka's famous 'toxin puzzle' is a focus of discussion, the (...) nature of deterrence, the rationality of morals, contractarian ethics, and the contemporary relevance of Hobbes' political thought. Incorporating important philosophical statements of problems and fresh contributions to the ongoing debate about rational intention this volume will interest not just philosophers but also political scientists and economists.

Many writers have attempted to develop criteria to demarcate between competent science and pseudo?science. Such attempts can be aimed at sizeable, organized endeavours, such as mesmerism and astrology, or at the level of individual practice. The latter is seen by some, such as Lugg, as more likely to be feasible and useful. This paper argues that parapsychology, due to its complexity and diversity, illustrates some of the problems of attempting to develop demarcation criteria for extensive endeavours. It is also suggested (...) that parapsychology may offer a productive ground for testing whether demarcation criteria can be successfully applied to practices in respect of predicting which will succeed and which will not. The conclusion is that, for demarcation efforts to be useful, they should pass some of their own criteria, such as falsifiability. (shrink)

When word pairs having a familiar order are sequentially flashed on a computer in their non-familiar order, , observers have a strong phenomenology of seeing them in familiar order . Reversal errors remained frequent even when participants obtained perceptual experience of reverse-display items by beginning with a block of longer-duration trials. A forced-choice order-detection procedure reduced but did not eliminate reversal errors, showing that “fast pairs” is a robust perceptual illusion. Even adjective + noun pairs showed reversal errors, and reversal (...) errors increased with the log frequency of the word pair, consistent with a strong role for statistical processing at the level of multi-word units.
