The world I grew up in believed that change and development in life are part of a continuous process of cause and effect, minutely and patiently sustained throughout the millenniums. With the exception of the initial act of creation ..., the evolution of life on earth was considered to be a slow, steady and ultimately demonstrable process. No sooner did I begin to read history, however, than I began to have my doubts. Human society and living beings, it seemed to (...) me, ought to be excluded from so calm and rational a view. The whole of human development, far from having been a product of steady evolution, seemed subject to only partially explicable and almost invariably violent mutations. Entire cultures and groups of individuals appeared imprisoned for centuries in a static shape which they endured with long-suffering indifference, and then suddenly, for no demonstrable cause, became susceptible to drastic changes and wild surges of development. It was as if the movement of life throughout the ages was not a Darwinian caterpillar but a startled kangaroo, going out towards the future in a series of unpredictable hops, stops, skips and bounds. Indeed, when I came to study physics I had a feeling that the modern concept of energy could perhaps throw more light on the process than any of the more conventional approaches to the subject. It seemed that species, society and individuals behaved more like thunder-clouds than scrubbed, neatly clothed and well-behaved children of reason. Throughout the ages life appeared to build up great invisible charges, like clouds and earth of electricity, until suddenly in a sultry hour the spirit moved, the wind rose, a drop of rain fell acid in the dust, fire flared in the nerve, and drums rolled to produce what we call thunder and lightening in the heavens and chance and change in human society and personality.LAURENS VAN DER POST, The Lost World of the Kalahari.

We introduce a novel paradigm for studying the cognitive processes used by listeners within interactive settings. This paradigm places the talker and the listener in the same physical space, creating opportunities for investigations of attention and comprehension processes taking place during interactive discourse situations. An experiment was conducted to compare results from previous research using videotaped stimuli to those obtained within the live face-to-face task paradigm. A headworn apparatus is used to briefly display LEDs on the talker's face in four (...) locations as the talker communicates with the participant. In addition to the primary task of comprehending speeches, participants make a secondary task light detection response. In the present experiment, the talker gave non-emotionally-expressive speeches that were used in past research with videotaped stimuli. Signal detection analysis was employed to determine which areas of the face received the greatest focus of attention. Results replicate previous findings using videotaped methods. (shrink)

The possible relationship between widespread unauthorized copying of microcomputer software (also known as software piracy) and level of moral judgment is examined through analysis of over 350 survey questionnaires that included the Defining Issues Test as a measure of moral development. It is hypothesized that the higher one''s level of moral judgment, the less likely that one will approve of or engage in unauthorized copying. Analysis of the data indicate a high level of tolerance toward unauthorized copying and limited support (...) for the hypothesis. The most plausible explanation for these findings is that software copying is perceived as an issue of low moral intensity. This study calls into question the software industry''s strategy of concentrating exclusively on institutional compliance with copyright rules, rather than working to raise the perceived moral intensity about software piracy at the individual level. As long as the issue remains low in moral intensity, the industry cannot expect significant shifts in copying behaviors. Individuals must become more aware of and concerned about the nature and magnitude of harm to society and to the rightful copyright owners from unauthorized copying before their attitudes and behaviors come to reflect higher levels of moral judgment.

This commentary focuses on four major points: (1) “Tacit knowledge” is not a complete explanation for imagery phenomena, if it is an explanation at all. (2) Similarities and dissimilarities between imagery and perception are entirely consistent with the depictive view. (3) Knowledge about the brain is crucial for settling the debate. (4) It is not clear what sort of theory Pylyshyn advocates.
We explore psychological contracts as mechanisms by which individuals gain influence in organizations. Using two distinct research settings and longitudinal analysis, we demonstrate that ideological contracts endow individuals with increased centrality in the organization’s influence network. More generally, we propose that an important outcome of different psychological contract types may be how they affect the nature of influence in organizations.

Intentionality, as Brentano originally introduced the term in modern philosophy, was meant to provide a distinctive characteristic definitively separating the mental from the physical.(1) Mental states have an intrinsic relationship to an object, to that which they are "about." Physical entities just are what they are, they cannot, by their very essence, refer to anything, they have no "outreach", as one might put it. Mental states have, as it were, an incomplete essence, they cannot exist at all unless they are (...) completed by something other than themselves, their object. Brentano's position is opposed to all theories which represent the mental as only extrinsically related to the world, that is, to all theories in which mental states are themselves self-sufficient for their own existence and only secondarily relate to the world by means of something external to their nature, e.g., neurological causation, divine intervention, or pre-established harmony. In these later cases, any mental act whatsoever could be related to any object, or indeed to none, for the relation is external to the nature of the act, it is superimposed on it by outside forces. Brentano's point is that a mental act has, by its very essence, an Intentional object without which it would not be a mental act. It would therefore appear that since causality is an external relationship which could in principle relate any two things regardless of their nature, the Intentional relation between an act and its object cannot be a causal relation.

This paper explores R. D. Laing's application of existential and phenomenological tradtions, specifically Hegel and Heidegger, to his groundbreaking work with psychotic process as well as psychotherapeutic practice more generally.
This paper explores the psychoanalytic conception of the unconscious and critiques it from a phenomenlogical perspective, especially Sartre and Heidegger, with a view to conceptualizing the unconscious from an ontological rather than psychological mindset.

The ability to predict the actions of other agents is vital for joint action tasks. Recent theory suggests that action prediction relies on an emulator system that permits observers to use information about their own motor dynamics to predict the actions of other agents. If this is the case, then predictions for self-generated actions should be more accurate than predictions for other-generated actions. We tested this hypothesis by employing a self/other synchronization paradigm where prediction accuracy for recording of self-generated movements (...) was compared with prediction accuracy for other-generated movements. As expected, predictions were more accurate when the observer’s movement dynamics matched the movement dynamics of the recording. This is consistent with that idea that the observer’s movement dynamics influence the predictions they generate. (shrink)

A working theory can involve a compromise between pragmatic application and pure theory. This is illustrated by the development of Coombs's theory of data. The original version of the theory purported to guide investigators in the use of scaling techniques, but subsequent revisions including a logico-mathematical statement of the theory do not show whether the practical recommendations made earlier still apply. These practical recommendations, some of which Coombs has discarded to obtain a comprehensive theory, are important in spite of shortcomings (...) as they reveal differences between attitude and mental test data. The different forms of Coombs's theory point to the existence of a general problem, how to find a compromise between practice and pure theory. (shrink)
Any discussion of Wittgenstein's philosophical thought would be incomplete without taking notice of the method he employs. Often criticized for his style and organization, many feel that they are indicative of his state of mind; that such a lack of rigid argumentation betrays an inadequacy within the arguments themselves. However, criticism of Wittgenstein along these lines only serves to demonstrate a superficial reading of his texts. Not simply content (or even able) to just present us with the results of his (...) investigations, Wittgenstein coaxes the reader into taking up an investigation of his own by means of an open dialogue. As a dialogue, we are not confronted with a traditional argumentative structure, i.e. the stating of theses and their subsequent defense. Rather, Wittgenstein attempts to draw the reader away from the obvious by means of an indirect method of discourse. (shrink)
This article presents a critique of Philip Pettit’s concept of ‘freedom as non-domination’ and provides an alternative theory of both domination and republican political freedom. I argue that Pettit’s neo-republican concept of domination is insufficient to confront modern forms of domination and that this hampers his concept of republican freedom and its political relevance under the conditions of modernity. Whereas the neo-republican account of domination is defined by ‘arbitrary interference’, modern forms of domination, I argue, are characterized by routinization and (...) systemic forms of control and subordination. In the end, the neo-republican account of domination is more appropriate for 17th- and 18th-century social institutions rather than those that persist under modernity. In its place, I propose a more dynamic concept of domination and rework the concept of freedom in order to place the republican tradition within the context of modernity itself. I argue that the core insight of republicanism is its emphasis on the arrangement and reformation of social institutions to enhance social freedom. From this, I argue that republicanism can take its place as a more attractive alternative to liberal theory. (shrink)

This paper provides an informal guide to young researchers in science and engineering as they progress for their first 10 or so years from the time that they first started thinking about doing a PhD. This advice is drawn, with examples and anecdotes, from my own research career which started at the Cambridge Engineering Department in 1958, and progressed through 48 years at University College London to a part-time chair that I now hold in Aberdeen. I hope it may encourage (...) and help tomorrow's scientists on whom the Earth's future very much depends. (shrink)
Recent magnetic resonance imaging (MRI) and pathological studies have indicated that axonal loss is a major contributor to disease progression in multiple sclerosis. 1 H magnetic resonance spectroscopy (MRS), through measurement of N -acetyl aspartate (NAA), a neuronal marker, provides a unique tool to investigate this. Patients with primary progressive multiple sclerosis have few lesions on conventional MRI, suggesting that changes in normal appearing white matter (NAWM), such (...) as axonal loss, may be particularly relevant to disease progression in this group. To test this hypothesis NAWM was studied with MRS, measuring the concentration of N -acetyl derived groups (NA, the sum of NAA and N -acetyl aspartyl glutamate). Single-voxel MRS using a water-suppressed PRESS sequence was carried out in 24 patients with primary progressive multiple sclerosis and in 16 age-matched controls. Ratios of metabolite to creatine concentration (Cr) were calculated in all subjects, and absolute concentrations were measured in 18 patients and all controls. NA/Cr (median 1.40, range 0.86–1.91) was significantly lower in NAWM in patients than in controls (median 1.70, range 1.27–2.14; P = 0.006), as was the absolute concentration of NA (patients, median 6.90 mM, range 4.62–10.38 mM; controls, median 7.77 mM, range 6.60–9.71 mM; P = 0.032). There was no significant difference in the absolute concentration of creatine between the groups. This study supports the hypothesis that axonal loss occurs in NAWM in primary progressive multiple sclerosis and may well be a mechanism for disease progression in this group. (shrink)
We propose a naturalistic version of the “guesser–knower” paradigm in which the experimental subject has an opportunity to choose which individual to follow to a hidden food source. This design allows nonhumans to display the attribution of knowledge to another conspecific, rather than a human, in a naturalistic context (finding food), and it is readily adapted to different species.
We may now briefly review the ground we have covered. We began by observing that a pugnacious instinct might be conceived in two ways: ( a )As a need or craving of the organism. ( b )As an instinct to fight in response to the thwarting of an impulse, especially one with instinctive motivation. With regard to the first possibility, we found that so far as the study of young children reveals, this explanation is unsound. Consideration of both the intrinsic (...) and extrinsic factors in aggressive behaviour indicates that pugnacity need never be assumed as its own motive, for it has significance always in relation to some more primary need. This need is, in the young, primarily a need for security, and the aggressiveness of children is mainly intended to be adaptive to this end. With regard to the second possibility, which defines pugnacity as instinctive from the side of response, present evidence would indicate that the angry emotional response (which is loosely termed a pugnacious response), far from being an inborn set behaviour pattern, is itself differentiated early in life from some more general undifferentiated avoidance reaction. The general conclusion which we have drawn from the above discussion, therefore, is that the concept of the instinct of pugnacity is, defined in the first manner, definitely contrary to fact, and, defined in the second manner, made obsolete by a more exact analysis of the data to hand. “It is commonly thought that the only hope for the student of society is the acquisition of knowledge; more facts, and still more facts is the common catch-phrase. But what is really needed is more insight into what facts have been gained. The mere accumulation of knowledge in itself is of little use: what really is needed is some means of using that knowledge. The student should constantly try to group his facts into still wider generalisations, he should learn what is more and what is less essential, what is primary and what is derived; for he will only be able to acquire the necessary economy of thought by confining himself to what is really essential in the growth and development of human society.” W.

This is a study in the philosophy of social science. It takes the form of a comparative critique of three contemporary approaches: ordinary language philosophy, hermeneutics and critical theory, represented here respectively by Ludwig Wittgenstein, Paul Ricoeur and Jürgen Habermas. Part I is devoted to an exposition of these authors' views and of the traditions to which they belong. Its unifying thread is their common concern with language, a concern which nonetheless reveals important differences of approach. For whereas ordinary language (...) philosophers tend to treat linguistic activity as the ultimate object of inquiry, both Ricoeur and Habermas regard it as a medium which betrays more fundamental dimensions of human experience and the social world. Part II complements the exposition with a critical analysis of its central themes: the conceptualisation of action, the methodology of interpretation, and the theory of reference and truth. The author defends many aspects of the work of Ricoeur and Habermas, such as the emphasis on power and ideology, the strategy of depth interpretation, and the link between consensus and truth; but he argues that there are serious deficiencies and obscurities in their work. He proposes solutions to these difficulties and concludes with a sketch of a critical and rationally justified theory for the interpretation of action - a critical hermeneutics. (shrink)
The viabiliry of Rahner’s “transcendental method” in the light of challenges posed by contemporary hermeneutics is explored through an analysis of what Rahner relatively early called “transcendental hermeneutics.” In tum, this is shown to be based upon Rahner’s understanding of how the trinitarian Word and Spirit interrelate.
During the last ten years John Beatty, Elisabeth Lloyd and I have argued that the semantic conception of theories is, in the context of biological theorizing, a richer conception of theory structure than the syntactic ("received view") conception. Specifically, I have argued semantic conception of theory structure better represents the structure of evolutionary theory and the relationship of this theory to phenomena. One aspect of the semantic conception that is in need of greater attention is the nature of explanation (...) on this conception. In this paper, I argue that the semantic conception provides a richer mo accurate account of scientific explanation, in particular, of evolutionary explanations. In essence, I argue that explanation involves an appeal to numerous theories in addition to the putative explanatory theory. Employment of these theories is not formally possible in a syntactic conception but is in a semantic conception. (shrink)
Cognitive control refers to the regulation of mental activity to support flexible cognition across different domains. Cragg and Nation (2010) propose that the development of cognitive control in children parallels the development of language abilities, particularly inner speech. We suggest that children’s late development of cognitive control also mirrors their limited ability to revise misinterpretations of sentence meaning. Moreover, we argue that for certain tasks, a tradeoff between bottom-up (data-driven) and top-down (rule-based) thinking may actually benefit performance in both children (...) and adults. Specifically, we propose that a lack of cognitive control may promote important aspects of cognitive development, like language acquisition and creativity. (shrink)
