This commentary is a review of the findings and ideas reported in the preceding nine articles on the effects of distraction on aspects of cognitive performance. The articles themselves deal with the disruptive effects of distraction on recall of words, objects and events, also on visual processing, category formation and other cognitive tasks. The commentary assesses the part played by “domain-general” suppression of distracting information and the “domain-specific” competition arising when tasks and distraction involve very similar material. Some forms of (...) distraction are meaningfully relevant to the ongoing task, and Treisman’s (1964) model of selective attention is invoked to provide an account of findings in this area. Finally, individual differences to vulnerability to distraction are discussed; older adults are particularly affected by distracting stimuli although the failure to repress distraction can sometimes prove beneficial to later cognitive performance.

Three experiments investigated level of processing effects on a variety of direct and indirect memory tasks, in the context of a processing theory of dissociations. Subjects studied words in five encoding conditions and received one of ten memory tests. In Experiment 1, four tests previously classified as conceptual showed a robust LOP effect, as did a direct perceptual test of graphemic cued recall. An indirect perceptual word fragment completion test was unaffected by LOP. Experiment 2 showed that a new indirect (...) version of a graphemic cued test was not affected by LOP. In Experiment 3, guided by a generation/recognition model, we constructed three new direct tests in which subjects identified words that were graphemically, phonologically, or semantically similar to studied words. The three tests differed in their sensitivity to study conditions, but LOP had no effect in any case, despite the involvement of deliberate conscious recollection. Contemporary explanatory frameworks couched as dichotomies do not provide an adequate account of the results. It seems necessary instead to specify the types of information activated by each encoding condition, the types of information required by each test, and how encoding and retrieval processes are modified by task instructions.

Aristotle'sPoeticsis a treatise notoriously difficult to understand, largely because of Aristotle's treatment of his theme, with its elliptical thought and loose terminology, but also because Aristotle's influence on subsequent drama and criticism makes it difficult to isolate the original thought from subsequent attempts at implementation or interpretation. However, as Aristotle devotes most of his treatise to tragedy—despite the wider subject he professes—and in discussing tragedy deals most extensively with plot, his views on the tragic plot should be reasonably clear. The (...) passages cited have some importance for the understanding of his views. (shrink)

The evolution of the equation of mass conservation in fluid mechanics is studied. Following early hydraulic approximations, and progress by Daniel and Johann Bernoulli, its first expression as a partial differential equation was achieved by d’Alembert, and soon given definitive form by Euler. Later reworkings by Lagrange, Laplace, Poisson and others advanced the subject, but all based their derivations on the conserved mass of a moving fluid particle. Later, Duhamel and Thomson gave a simpler derivation, by considering mass flow into (...) and out of a fixed portion of space. The later propagation of these derivations in nineteenth-century British textbooks and treatises is also examined, including Maxwell’s on the kinetic theory of gases. (shrink)

Lines 380–7 have been much discussed, sometimes in isolation, without due regard for context in speech, scene, and play; and sometimes with regard primarily to the history of ideas, or of Greek moral values. Phaidra states that virtue may be subverted, despite knowledge, by pleasure, of which αὶδώς—dual, harmless and harmful—is an instance. A notorious problem of interpretation centres on the related questions of how αὶδώς, shame can be listed among ήδοναί, pleasures; and of what is meant by dual αὶδώς. (...) The interpretation here advanced is bold, but in essence simple: in this context, αὶδώς is a euphemistic metonymy for ἔρως, which is harmless and pleasurable in its proper place, but potentially troublesome or painful.

Hamaker's conjecture κομâ (for τολμâ,sic) at Lysias 16.18 was adopted by Rauchenstein in his influential edition of 1869 and soon given powerful endorsement by Jebb and by Shuckburgh. Successive later editors and commentators have seen no reason to demur: Thalheim, Adams, Hude, Gernet and Bizos, Lamb, and finally Edwards and Usher all adopt κομâ, and, where they comment, unanimously cite Aristophanic parallels (especiallyEq.580) in support of a connection between longhaired affectation and ‘oligarchic’ affiliations; some also adduce the expression ảπ’ὂΨεως in (...) justification. But this is an egregious instance of unwarranted tampering with a sound text. τóλμα is a quality conspicuously displayed by Mantitheus, on his own account of his character, words, and actions.

W. D. Furley, ‘Phaidra's pleasurable aidos ’, CQ 46, 84–90 is in part a response to my article, ‘ in Euripides’ Hippolytos 373–430: review and reinterpretation’, JHS 113, 45–59. Furley states that I suggest that aidos is ‘a euphemism for aidoia, the genitals, thus = sex’. This is an over-simplification. I argue that ‘in this context, is a euphemistic metonymy for ’; that ‘in terms of linguistic use, may be viewed as the natural reaction to the … just as is (...) to ; and hence that ‘the linguistic associations and semantic nuances of are sufficient to allow the word, in appropriate contexts, to mean “sex”’.

The appearance of Nan Dunbar's important commentary onBirdsis to be welcomed. Inevitably, however, such a volume requiresaddenda et corrigenda; and already the author must be collecting material for a second edition. Here is somepabulum. On the passage cited, Dunbar comments, ‘The difficulties of this sentence stem from uncertainty over (a) the form and sense of the main verb … and (b) the point of χαραδρι⋯ν μιμο⋯μενος and its connection with what precedes …’.

On Anatomy is the shortest treatise preserved in the Hippocratic Corpus. It describes the internal configuration of the human trunk. The account is for the most part descriptive, function being largely disregarded and speculation completely eschewed. Though systematic it is unsophisticated: two orifices for ingestion are linked by miscellaneous organs, vessels, and viscera to two orifices for evacuation. There is a clear progression in two parallel sections: first, trachea to lung, lung described, location of heart, heart described, kidneys to bladder, (...) bladder described, bladder to genitals, conclusion; and second, oesophagus to belly, location of diaphragm, location of spleen, location and description of belly, belly to intestine/colon, colon to rectum and anus, conclusion. The text offers good basic topographical or regional anatomy. That the work is concerned with human anatomy is certain from the precise description of lung and liver, with features peculiar to human organs; and is corroborated by frequent references to comparative anatomy, with which familiarity is apparently assumed. Such anatomical knowledge, based on extensive observation of animals, may have been corroborated by some human dissection, perhaps of the aborted foetus or exposed infant, in conjunction with opportunistic observation of war wounded and accident victims. While the syntax is bald, telegraphic, and asyndetic, the vocabulary is recondite, and poetic. There is erratic omission of the article and recurrent use of compendious comparisons. These features suggest that Anat. may be an abridgement of a fuller and more flowery account; this hypothesis is supported by several passages where erroneous or unclear information apparently results from excessive compression or imperfect comprehension of a source.

This volume contains contributions from friends and colleagues who have been influenced in one way or another by this accomplished psychologist.

This article critically considers calls for the precautionary principle to inform judicial decision making in a private law context in light of the Hoffman litigation, where it is alleged that the potential for genetic contamination from genetically modified (GM) crops causes an unreasonable interference with the rights of organic farmers to use and enjoy their lands, giving rise to an actionable nuisance. Applying the precautionary principle in this context would likely privilege non-GM land uses over GM uses, given the latter's (...) uncertain environmental impacts. Through a comparison of the institutional characteristics and respective roles of public and private regulation, the authors argue that the private law context, which lacks democratic accountability and has a limited ability to address complex scientific issues, is poorly suited to apply the diffuse, policy-based risk allocation considerations raised by the precautionary principle.
