Consciousness: a neurological perspective

Consciousness is a state so essentially entwined with human experience, yet so difficult to conceptually define and measure. In this article, we explore how a bidimensional model of consciousness involving both level of arousal and subjective awareness of the contents of consciousness can be used to differentiate a range of healthy and altered conscious states. These include the different sleep stages of healthy individuals and the altered states of consciousness associated with neurological conditions such as epilepsy, vegetative state and coma. In particular, we discuss how arousal and awareness are positively correlated in normal physiological states with the exception of REM sleep, while a disturbance in this relationship is characteristic of vegetative state, minimally conscious state, complex partial seizures and sleepwalking.

Roles for Values in Scientific Activities

My aim in this paper is to rebut objections that have been made of the account of the various roles for values in scientific activities that I have developed, initially in my book Is Science Value Free?, in response to criticizing the proposal that science is value free. Specifically I respond to objections that my account does not recognize the significance of basic science, and that my defense of the ideal of impartiality cannot be sustained.     

Same duties,different motives: ethical theory and the phenomenon of moral motive pluralism

Viewed in its entirety, moral philosophizing, and the moral behavior of people throughout history, presents a curious puzzle. On the one hand, interpersonal duties display a remarkably stable core content: morality the world over enjoins people to keep their word; refrain from violence, theft and cheating; and help those in need. On the other hand, the asserted motives that drive people’s moral actions evince a dazzling diversity: from empathy or sympathy, to practical or prudential reason, to custom and honor, cultural identity, excellence and independence, faith and spirituality, narrative and beauty, and more besides. I term this twin phenomenon—a core of fixed moral duties driven by diverse motives—“moral motive pluralism.” In this article, I marshal evidence to show the prevalence of the phenomenon. Contrary to widespread assumptions, across generations and cultures, diverse motives drive different people to perform their moral duties. But despite this diversity, each different motive impels conscientious compliance with the same core moral duties. I argue this phenomenon undermines key types of evidence commonly employed to justify popular moral philosophies, and provides us with reason to seriously consider certain sorts of ethical theories—especially “functionalist” accounts of morality.     

Potential Criminals?: Australian Consumers of X-rated Videos

This study presents results of a nation-wide survey of 348 mail-order and adult shop purchasers of X-rated videos in Australia. The sample was drawn from those who purchased X-rated videos from a nation-wide distributor in late 1992. The sociodemographic profile, consumption history, viewing habits, and uses of the X-rated videos by the consumers are discussed. The findings are presented as an initial attempt to study the regular consumers of pornographic videos in a country with a standardized censorship system which regulates the content of X-rated videos. The results are also examined in the light of previous theoretical and empirical examinations of the purchasers and consumers of X-rated videos in relation to issues of criminalization.     

Remembering more than meets the eye: a study of memory confusions about incomplete visual information

The purpose of this series of four experiments was to examine the possible role of spontaneous imagery in memory confusions about the way in which visual information had been experienced. After viewing pictures of familiar objects, complete or incomplete in visual form, participants were asked to remember the way in which the objects had been presented. Although, as predicted, memory for the objects themselves was quite good, participants falsely remembered seeing complete versions of pictures that were actually presented as incomplete. These false reports were observed across a variety of encoding and testing conditions. The results suggest that the false reports (referred to here as completion errors) are due to internal representations based on filling-in processes in response to the encoding of incomplete visual information. As such, the results also speak to alternative explanations for the completion errors and, more broadly, to theoretical perspectives that draw on filling-in processes when accounting for object identification and object memory.     

College Students' Knowledge,Attitudes, and Behaviors Regarding Organ Donation: An Integrated Review of the Literature1

The current paper provides an integrated review of research literature on college students' knowledge, attitudes, and intentions regarding organ and tissue donation (OTD). Findings across 27 studies indicate that (a) students reported a lack of information and knowledge on OTD; (b) 23% reported signing an organ card or state organ donation registry; (c) positive attitudes were reported toward donation; (d) surveyed students indicated a willingness to become organ donors; and (e) 36% reported having conversations with family about OTD. Self‐efficacy and normative influence theory are recommended as promising theoretical approaches to studying OTD in college student samples.     

On Reinstating “Part I” and “Part II” to Wittgenstein’s Philosophical Investigations – A Supplementary Note

I have argued previously in this journal for the reinstatement of the titles “Part I” and “Part II” to Wittgenstein’s Philosophical Investigations, these having been replaced by “Philosophical Investigations” and “Philosophy of Psychology – A Fragment” by the editors of the 4th edition. My case for reinstatement was based principally on the written testimonies of Wittgenstein’s literary executors and first editors of the Investigations. Since the publication of my paper, further evidence of Wittgenstein’s publication intentions, from the diaries of his friend M. O’C. Drury, has come to my attention, which I now present. The current editors are urged to respond.
