Sustained attention, a key cognitive skill that improves during childhood and adolescence, tends to be worse in some emotional and behavioural disorders. Sustained attention is typically studied in non-affective task contexts; here, we used a novel task to index performance in affective versus neutral contexts across adolescence (N = 465; ages 11–18). We asked whether: (i) performance would be worse in negative versus neutral task contexts; (ii) performance would improve with age; (iii) affective interference would be greater in younger adolescents; (...) (iv) adolescents at risk for depression and higher in anxiety would show overall worse performance; and (v) would show differential performance in negative contexts. Results indicated that participants performed more poorly in negative contexts and showed age-related performance improvements. Those at risk of depression performed more poorly than those at lower risk. However, there was no difference between groups as a result of affective context. For anxiety there was no difference in performance as a function of severity. However, those with higher anxiety showed less variance in their reaction times to negative stimuli than those with lower anxiety. One interpretation is that moderate levels of emotional arousal associated with anxiety make individuals less susceptible to the distracting effects of negative stimuli. (shrink)

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

Stanovich & West (S&W) appear to overlook the adaptivity of variation. Behavioral variability, both between and within individuals, is an absolute necessity for phylogenetic and ontological adaptation. As with all heritable characteristics, inter-individual behavioral variation is the foundation for natural selection. Similarly, intra-individual variation allows a broad exploration of potential solutions. Variation increases the likelihood that more optimal behaviors are available for selection. Four examples of the adaptivity of variation are discussed: (a) Genetic variation as it pertains to behavior and (...) natural selection; (b) behavioral and cognitive aspects of mate selection which may facilitate genetic diversity; (c) variation as a strategy for optimizing learning through greater exploration; and (d) behavioral variation coupled with communication as a means to propagate individually discovered behavioral success.

I do not for a moment question the fact that many people have experiences of a special type which may be termed “religious”, The extent to which religious experience may be regarded as a reasonably common phenomenon in present-day Britain is shown clearly by David Hay in his Exploring Inner Space, Harmondsworth 1982. that such experiences often involve reference to something which appears to display a radical unlikeness to all else and that they are therefore in some sense inexpressible. Doubtless (...) the ideas I have put forward about the possible source of such unlikeness and ineffability might suggest models of God which would not find much theological approval, at least within any mainstream theistic tradition, since some sort of pantheism seems inevitably to be implied. But however this might be, the concept of radical unlikeness as it has been analyzed here can, I think, help us towards understanding certain problematic areas in religion quite apart from the issue of intelligibility, which has been the focus of this discussion. To begin with, radical unlikeness suggests a way in which the historical continuity of concepts of the transcendent might be upheld against the discontinuity suggested by the diversity of interpretations through which they have moved. Ancient and modern outlooks on, say, God differ enormously, as indeed do the range of co-temporal accounts at many particular moments. But, by and large, theologians firmly maintain that it is a single and unchanging phenomenon which is being dealt with. Unless we can point to some common element which is both specific enough to create a binding sense of common tradition, yet never completely expressed by any attempt at understanding it within that tradition (thus persistently demanding new attempts to apprehend it), then given the widely differing views of God within, for example, the Christian community, it is difficult to see how we could assume that in fact they all stemmed from the same source and were talking about the same thing. The idea of radical unlikeness could provide an element with just these required characteristics: it could be seen as what all the accounts attempt to net, with varying degrees of adequacy, within their offered interpretations. It could be seen as what remains constant, constantly elusive yet constantly generative of fresh attempts to apprehend it, throughout a history of intra-religious diversity. This sort of explanation could, presumably, be applied to the intra-religious diversity of the non-Christian traditions too.Secondly, radical unlikeness might suggest a possible way of understanding inter-religious diversity in a way which allows that whilst such diversity exists, whilst the differences between religions are real, they are grounded in a similar root-experience. It may, at first sight, seem difficult to continue thinking of the various religious traditions as truly separate phenomena if they are taken as being grounded on experiences whose ineffability stems from the unlikeness of experiencing things as a whole. Here we must stress again that if they are to be considered intelligible, radically unlike experiences cannot be considered completely so - or putting this another way, we cannot more than approach experience of totality. Sense can be given to religious claims of ineffability by suggesting experience of near totality, where we reach the last point on the scale of inclusiveness which complies with the logical criteria demanded of something for it to be possible for us to be aware of it. We might thus attempt an explanation of inter-religious diversity based on the view that Hinduism, Buddhism, Christianity, Islam etc. acquire their differences from the different elements included in their experience of near totality. Taking totality to be represented by the scale of one to ten, Hinduism might be seen as grounded on experience of 1-2-3-4-5-6-7-9-10, Buddhism on experience of 1-3-4-5-6-7-8-9-10 and so on. The resulting dissimilarities are thus centred not on different types of experience, but on different areas of inclusiveness. This is, of course, to suppose that the various religious traditions are all based on the same degree (as opposed to the same elements) of inclusiveness, but it is by no means clear that such a supposition is justified. Continuing with our decimal analogy, might it not be suggested that whilst Christianity stemmed from experience of 2-3-4-5-6-7-8-9-10, Jainism was founded on a less extensive encounter with the divine (say 4-5-6-7-8-9-10)? It is, however, uncertain how we can compare and evaluate different religious traditions in such a way as to be able to comment on such claims. A definite danger of comparative religion is that by concentrating on establishing and exploring inter-religious likenesses, it may obscure the radical unlikeness of religious phenomena. It should be borne firmly in mind that such likenesses as may be established within comparative studies may not win religious phenomena a place within our understanding comparable to objects of more everyday concern. Statements found in the Old Testament, the Qur'an and the Vedas, for example, may, on occasion, be alike, but at the end of the day such things are often alike only, or chiefly, in so far as they display the same radical unlikeness in relation to the non-religious elements in our outlook.The analysis of radical unlikeness and ineffability which has been advanced might also suggest a way in which certain passages in religious writings could be understood, passages which at first sight can be seriously perplexing. If, for example, to return to the quotation given in the introductory section of this paper, we continue to think of accounts of the nature of Shiva as being attempts to describe some discrete, objective entity, then it is inevitable that either we will share the Puranic writer's puzzlement or that much of what we read about Shiva will appear as the muddled and extravagant thinking thrown up by an uncritical and over-fertile mythological imagination, consisting of little more than a hotch-potch of contradictory elements. But if we see such accounts as attempting to say something about everything, as symbols of near totality stemming from experiences which verge on the holistic, then what we read - with all its ambiguities - may become somewhat more meaningful. Thus W.D. O'Flaherty comments that Shiva “embodies all of life in all its detail at every minute” (Asceticism and Eroticism in the Mythology of Shiva, London 1973, p. 315). Similarly Alain Dani41ou sees Shiva, ultimately, in terms of his being "the supreme state of reality" beyond whom there is only "non-existence" (Hindu Polytheism, London 1964, p. 190).This analysis of ineffability and intelligibility seeks to introduce for debate a possible way of understanding the radical unlikeness which accounts of religious experience apparently attempt to speak about. It does not, however, claim to present an exhaustive treatment of the issues raised, on the contrary, I am conscious of many shortcomings and omissions. For instance, it remains to be seen under precisely what conditions something counts as being an elucidating likeness (presumably all experiences are, for example, temporal, yet temporality alone would not seem to offer a particularly elucidating comparison). Moreover, the degree to which appeal to likeness is allowed operation in actual accounts of religious experience needs to be explored. In addition, the notion of categorizing experiences according to the extent to which they approach a point of total inclusion requires careful clarification. To begin with, according to what criteria could we establish that one experience was more inclusive than another? However, such issues can only be mentioned here, any adequate consideration of them would require a separate paper.In conclusion, I would suggest that to use radical unlikeness and/or ineffability simply as devices by which to halt any process of investigation, proclaiming that the thing in question is not like anything and so is beyond all words, risks making unintelligible and placing beyond all further inquiry an important and extensive area of human experience. As William Alston put it, to label something ineffable in an unqualified way is to shirk the job of making explicit the ways in which it can be talked about. William P. Alston, “ineffability”, Philosophical Review 65 (1956), 522. It is surely more accurate to take ineffability as a “qualifier”I.T.

About one third of patients with epilepsy have seizures refractory to the medical treatment. Electrical stimulation mapping is the gold standard for the identification of “eloquent” areas prior to resection of epileptogenic tissue. However, it is time-consuming and may cause undesired side effects. Broadband gamma activity recorded with extraoperative electrocorticography during cognitive tasks may be an alternative to ESM but until now has not proven of definitive clinical value. Considering their role in cognition, the alpha and beta bands could further (...) improve the identification of eloquent cortex. We compared gamma, alpha and beta activity, and their combinations for the identification of eloquent cortical areas defined by ESM. Ten patients with intractable focal epilepsy participated in a delayed-match-to-sample task, where syllable sounds were compared to visually presented letters. We used a generalized linear model approach to find the optimal weighting of each band for predicting ESM-defined categories and estimated the diagnostic ability by calculating the area under the receiver operating characteristic curve. Gamma activity increased more in eloquent than in non-eloquent areas, whereas alpha and beta power decreased more in eloquent areas. Diagnostic ability of each band was close to 0.7 for all bands but depended on multiple factors including the time period of the cognitive task, the location of the electrodes and the patient’s degree of attention to the stimulus. We show that diagnostic ability can be increased by 3–5% by combining gamma and alpha and by 7.5–11% when gamma and beta were combined. We then show how ECoG power modulation from cognitive testing can be used to map the probability of eloquence in individual patients and how this probability map can be used in clinical settings to optimize ESM planning. We conclude that the combination of gamma and beta power modulation during cognitive testing can contribute to the identification of eloquent areas prior to ESM in patients with refractory focal epilepsy.

High-spin states in the odd-odd N = Z nucleus Co-54 have been investigated by the fusion-evaporation reaction Si-28(S-32,1 alpha 1p1n)Co-54. Gamma-ray information gathered with the Ge detector array Gammasphere was correlated with evaporated particles detected in the charged particle detector system Microball and a 1 pi neutron detector array. A significantly extended excitation scheme of Co-54 is presented, which includes a candidate for the isospin T = 1, 6(+) state of the 1f(7/2)(-2) multiplet. The results are compared to large-scale shell-model (...) calculations in the fp shell. Effective interactions with and without isospin-breaking terms have been used to probe isospin symmetry and isospin mixing. A quest for deformed high-spin rotational cascades proved negative. This feature is discussed by means of cranking calculations. (shrink)

Two rotational bands have been identified and characterized in the proton-magic N = Z + 1 nucleus Ni-57. These bands complete the systematics of well-and superdeformed rotational bands in the light nickel isotopes starting from doubly magic Ni-56 to Ni-60. High-spin states in Ni-57 have been produced in the fusion-evaporation reaction Si-28(S-32, 2p1n)Ni-57 and studied with the gamma-ray detection array GAMMASPHERE operated in conjunction with detectors for evaporated light charged particles and neutrons. The features of the rotational bands in Ni-57 (...) are compared to those of neighbouring isotopes and interpreted by means of configuration-dependent cranked Nilsson-Strutinsky calculations. The two observed high-spin bands are considered signature partners and assigned to configurations with one 1g(9/2) proton and one 1g(9/2) neutron, resulting in an unambiguous understanding of the energetically favoured signature alpha = -1/2 band but a somewhat less satisfactory description of the signature alpha = +1/2 band.
