Why the handicapped child case is hard

This paper discusses the handicapped child case and some other variants of Derek Parfit's non-identityproblem (Parfit, 1984) The case is widely held to show that there is harmless wrongdoing, and that amoral system which tries to reduce wrongdoing directly to harm (``person-affecting morality')is inadequate.I show that the argument for this does not depend (as some have implied it does) on Kripkean necessity of origin. I distinguish the case from other variants (``wrongful life cases') of the non-identityproblem which do not bear directly on person-affecting morality as I understand it. And finally, I describe a respect in which the handicapped child case is puzzling and counter-intuitive, even on the supposition that it is a case of harmless wrongdoing. I conclude that the case is ``hard': it will take more than the rejection of person-affecting morality to remove its puzzling character.     

Modal Fictionalism and Compositionality

Modal fictionalists propose to defuse the unwanted ontological commitments of modal realism by treating modal realism as a fictional story, and modal assertions as assertions, prefixed by a fictionalist operator, that something is true in that story. However, consideration of conditionals with modal antecedents raises the problem ofembedding, which shows that the simple prefixing strategy cannotsucceed. A compositional version of the fictionalist strategy isdeveloped and critiqued, and some general semantic morals aredrawn from the failures of both strategies.     

Neighbourhood density, word frequency, and spelling-sound regularity effects in naming: similarities and differences between skilled readers and the Dual Route Cascaded Computational model.

An experiment with skilled readers and a series of simulations with the Dual Route Cascaded model (Coltheart, Rastle, Perry, Langdon, & Ziegler, 2001) investigated the joint effects of stimulus quality and Neighbourhood Density (N) in nonword naming. Neighbourhood Density and stimulus quality yielded additive effects on RT for skilled readers whereas the model produced an interaction between these factors. A further set of simulations show that DRC also produces an interaction between stimulus quality and (1) word frequency, (2) spelling-sound regularity, and, (3) nonword letter length. None of these three factors interact with stimulus quality in performance by skilled readers. It is suggested that DRC's assumption of cascaded processing throughout represents a central problem. A proposal as to how the model can be modified to accommodate these and other problematic data is discussed.     

The Frequency of Prayer,Meditation and Holistic Interventions in Addictions Treatment: A National Survey

This study examines the prevalence of endorsing the twelve step approach and the use of prayer, meditation, and holistic techniques in a national sample of 139 substance abuse treatment centers. Ninety one percent of the programs endorsed a twelve step orientation. Twenty six percent of the programs actively used prayer and 58% used meditation as a component of treatment. Thirty three percent of the programs used some form of a self-designated holistic technique. There was a divergent range of techniques that were used by programs, falling into four broad categories: (1) nutrition, exercise, relaxation and physical health; (2) recreation and adventure-based activities; (3) religious and spiritual practices; and (4) the use of specific therapy modalities.     

The Role of the Group in Individual Functioning: School Identification and the Psychological Well-Being of Staff and Students

Many studies have demonstrated that organisations exert a powerful impact on their members, but the mechanisms through which this occurs are not well understood. In the present paper, using social identity and self-categorisation theories as theoretical frameworks, we explore the role that social identity plays in affecting individual well-being of staff ( N = 113) and students ( N = 693) in two Australian high schools. Well-being includes positive aspects of personal functioning, such as self-esteem, positive affect, and job involvement, but also negative aspects, such as depression, anxiety, loss of emotional control, aggressive and disruptive behaviour. In line with predictions, social identification was significantly related to, and mediated the relationship between, organisational factors and individual psychological well-being. This work provides a bridge between social psychological concepts and the clinical and educational domains. It reinforces the need to integrate the role of the social self and social identity processes in understanding the (individual) psychology of the person.     

Hiding and finding: The relationship between visual concealment and visual search

As an initial step toward developing a theory of visual concealment, we assessed whether people would use factors known to influence visual search difficulty when the degree of concealment of objects among distractors was varied. In Experiment 1, participants arranged search objects (shapes, emotional faces, and graphemes) to create displays in which the targets were in plain sight but were either easy or hard to find. Analyses of easy and hard displays created during Experiment 1 revealed that the participants reliably used factors known to influence search difficulty (e.g., eccentricity, target—distractor similarity, presence/absence of a feature) to vary the difficulty of search across displays. In Experiment 2, a new participant group searched for the targets in the displays created by the participants in Experiment 1. Results indicated that search was more difficult in the hard than in the easy condition. In Experiments 3 and 4, participants used presence versus absence of a feature to vary search difficulty with several novel stimulus sets. Taken together, the results reveal a close link between the factors that govern concealment and the factors known to influence search difficulty, suggesting that a visual search theory can be extended to form the basis of a theory of visual concealment.
