DOUGHNUTS AND DICKIE

In this paper, I assess Dickie's institutional theory of art. I compare the earlier and later forms of the theory, and I point to various problems of detail with these accounts. I then proceed by arguing that Dickie's definition excludes Krispy Kreme doughnut boxes from possessing the status of being works of art, and it excludes those who made them from possessing the status of being artists. The intention is not to offer a counter example to Dickie's account. Rather, the complaint is that there could be no philosophical point or interest in a concept of art which excludes these doughnut boxes. The best way to see this is by contrast with a concept of art that includes them. Thus I outline what I call a ‘creative’ account. What we want is a concept of art which helps us understand a certain phenomenon in the world – the phenomenon that we call ‘art’. In this light, I argue that Dickie's institutional theory tells us nothing about why people want to make art and nothing about why they want to experience it. By contrast, the creative theory, which embraces both doughnut boxes and things in galleries, is more explanatory.     

Peer group processes and adolescent health-related behaviour: More than ‘peer group pressure’?

This paper argues that ‘peer group pressure’ conveys an individualistic and hence inadequate account of the group processes involved in adolescents' adoption of health-related behaviours such as smoking and drinking. We describe traditional analyses of adolescent peer processes, illustrate how these contain a series of individualistic assumptions about peer interactions/social influence processes, and describe how these structure the analysis of adolescent health-related behaviour and health education interventions. We highlight the inadequacies of these analyses, outline an alternative and draw out its implications for health education.     

Whither (European) evaluation methodology?

Quasi-experimental evaluation methods promised to provide a way of testing and improving solutions to social problems. These methods have been found wanting. Alternative approaches, including “pragmatic evaluation,” “naturalistic evaluation,” and “pluralist evaluation” are also shown to be unsatisfactory. The initial promise of the evaluation movement has been disappointed. Realistic evaluation is advocated as an alternative to existing forms of evaluation. It is rooted in some European traditions in epistemology, ontology, and social theory. It offers a framework within which rigorous outcome evaluations can be undertaken with results that can inform policy and practice. He is president of the Research Committee on Methodology of the International Sociological Association. He is seconded part-time to the Home Office Police Research Group as a research consultant. An earlier version of this paper was presented at the founding conference of the European Evaluation Society, The Hague, 1–2 December, 1994.     

Why manifold substantivalism is probably not a consequence of classical mechanics

This paper develops and defends three related forms of relationism about spacetime against attacks by contemporary substantivalists. It clarifies Newton's globes argument to show that it does not bear on relations that fail to determine geodesic motions, since the inertial effects on which Newton relies are not simply correlated with affine structure, but must be understood in dynamical terms. It develops remarks by Sklar and van Fraassen into relational versions of Newtonian mechanics, and argues that Earman does not show them to trivialize the debate.     

Developing algorithms to enhance the sensitivity of cancellation tests of visuospatial neglect

We describe a set of algorithms that enhance the sensitivity of cancellation tests used in assessing visuospatial neglect. The algorithms can be readily implemented on a computer and can provide temporal and nontemporal data on strategies used during cancellation. We also present preliminary results from a group of 68 right-hemisphere brain-damaged patients and 12 age-matched control participants, which demonstrate the clinical significance of the measures we have defined.     

Stroop interference: An input and an output phenomenon

Three theories of Stroop interference are considered: perceptual conflict theory (Hock and Egeth, 1970), response competition theory (Morton, 1969) and conceptual encoding theory (Seymour, 1977). The first two fail to provide a full explanation of the available data, and Seymour's evidence is incomplete. Two experiments are reported. In the first, typical Stroop interference occurs in naming colour patches. In the second, subjects responded to colour patches with learned letter name responses. Both stimulus-related (incongruent colour names) and response-related (incongruent letters) distractors produced interference. These results indicate that any theory which assumes only a single locus for interference is incomplete. Conceptual encoding conflict and a modified form of response competition are suggested as possible dual mechanisms for Stroop interference effects.     

Language as shaped by the brain

It is widely assumed that human learning and the structure of human languages are intimately related. This relationship is frequently suggested to derive from a language-specific biological endowment, which encodes universal, but communicatively arbitrary, principles of language structure (a Universal Grammar or UG). How might such a UG have evolved? We argue that UG could not have arisen either by biological adaptation or non-adaptationist genetic processes, resulting in a logical problem of language evolution. Specifically, as the processes of language change are much more rapid than processes of genetic change, language constitutes a "moving target" both over time and across different human populations, and, hence, cannot provide a stable environment to which language genes could have adapted. We conclude that a biologically determined UG is not evolutionarily viable. Instead, the original motivation for UG--the mesh between learners and languages--arises because language has been shaped to fit the human brain, rather than vice versa. Following Darwin, we view language itself as a complex and interdependent "organism," which evolves under selectional pressures from human learning and processing mechanisms. That is, languages themselves are shaped by severe selectional pressure from each generation of language users and learners. This suggests that apparently arbitrary aspects of linguistic structure may result from general learning and processing biases deriving from the structure of thought processes, perceptuo-motor factors, cognitive limitations, and pragmatics.     

The Utility of the SASSI‐3 in Early Detection of Substance Use Disorders in Not Guilty by Reason of Insanity Acquittees: An Exploratory Study

Previous studies have shown the Substance Abuse Subtle Screening Inventory‐3 (G. Miller, 1999) to be valid in classifying substance use disorders in forensic and mentally ill populations. The authors found that it also correctly classified substance use disorders in the understudied not guilty by reason of insanity population.
