This book defends the radical thesis that no physical object has any of the colours we experience it as having.

Three experiments explore the role of working memory in motor skill acquisition and performance. Traditional theories postulate that skill acquisition proceeds through stages of knowing, which are initially declarative but later procedural. The reported experiments challenge that view and support an independent, parallel processing model, which predicts that procedural and declarative knowledge can be acquired separately and that the former does not depend on the availability of working memory, whereas, the latter does. The behaviour of these two processes was manipulated (...) by providing or withholding visual (and auditory) appraisal of outcome feedback. Withholding feedback was predicted to inhibit the use of working memory to appraise success and, thus, prevent the formation of declarative knowledge without affecting the accumulation of procedural knowledge. While the first experiment failed to support these predictions, the second and third experiments demonstrated that procedural and declarative knowledge can be acquired independently. It is suggested that the availability of working memory is crucial to motor performance only when the learner has come to rely on its use. (shrink)

In this paper I wish to propose and defend a form of the Representative Theory of Perception. According to this version of the theory, when a subject perceives some object x to be in a state P1 he does so by being aware of some modfication M1 of some object E. The subject's way of perceiving any one of a range of objects x,y,z, … is that of being aware of some modification of E. It will be a necessary condition (...) of someone's perceiving x to have property P1 that E be modified in some way. And in order for the modifications of E to be representations, a given property P1 will need to be causally related, characteristically, to one or more specific modifications, M1,M2, … Mn, of E. symbolized by ‘X'.).

The only explicit indication in the text of Ammianus Marcellinus as to the historian's origin comes in the famous epilogue to the Res Gestae, that he had written ‘as once a soldier, and a Greek’ , supported by various passages in which he refers to the Greek language as his own. The evidence that, through the length and breadth of the Greek-speaking world, we should look to Syrian Antioch for his place of origin, is provided by the orator of that (...) city, Libanius, in a letter written late in 392 ‘to Marcellinus’. The purpose of this article is to set out explicitly the arguments for the identification of Libanius' correspondent as Ammianus Marcellinus in the light of the recent challenges to the accepted view offered by G. W. Bowersock, C. W. Fornara, and T. D. Barnes. Since the discussion requires that the letter be considered in detail, it is given here, in Foerster's Teubner text followed by a translation of Libanius' often very allusive language. (shrink)

Michael J. Zimmerman explores whether and how our ignorance about ourselves and our circumstances affects what our moral obligations and moral rights are. He rejects objective and subjective views of the nature of moral obligation, and presents a new case for a 'prospective' view.

Although the existence of tachyons is not ruled out by special relativity, it appears that causal paradoxes will arise if there are tachyons. The usual solutions to these paradoxes employ some form of the reinterpretation principle. In this paper it is argued first that the principle is incoherent, second that even if it is not, some causal paradoxes remain, and third, the most plausible “solution,” which appeals to boundary conditions of the universe, will conflict with special relativity.

This paper takes the case of the proposed building of the Traveston dam on the Mary River in Australia to examine the ways postcolonial power relations are played out in city/regional relationships to further the interests of the city. Postcolonialism is concerned with unravelling multiple histories of colonialism, and identifying the reproduction, contestation, ambivalence and transformation of modes of domination and subordination in colonial relations. Political contingencies and contestations by residents, farmers, traditional Indigenous owners and environmentalists seeking to protect endangered (...) species are examined to highlight the dominance of Western anthropocentric, technocentric, and eurocentric epistemologies in political, ecological, environmental, biotheical debates.

Upshot: In his latest book, Lawrence Shapiro analyzes three main themes of embodied cognition that are claimed to make it distinct from traditional, disembodied research on cognition. The author provides a lucid comparison of the “old” and the “new” cognitive science, thereby often referring to enactivism, which most certainly makes his book interesting for constructivists.

In an approach to quantify the locomotor response to environmental stimuli in fishes and its central control mechanisms, initially stochastic models of spontaneous locomotor behavior are being formulated. In the present paper, the locomotor patterns of three active nurse shark,Ginglymostoma cirratum, in six experiments are converted into 17 locomotor variables and found to have definite time series structure. Sixty-seven of the 102 first order serial correlation coefficients are statistically significant, the incidence rate of which differs between experiments and between locomotor (...) variables. The percent residual variation about an autoregressive equation is transformed by a Fisher's z statistic and the means are found to differ significantly among experiments and among variables. The experiment by variable interaction is very low implying a consistency in the ranks of the variables despite the wide differences in their absolute levels over the experiments. This suggests the existence of a relatively rigid albeit occasionally latent locomotor control mechanism in the central nervous system. (shrink)
