We briefly presented either the letter ‘b’ or the letter ‘h’ to participants who were instructed to respond by saying the letter that was not shown. This binary version of the exclusion task avoids problems with assessing baseline completion rates. When the letters were shown for 5–10 ms participants erroneously responded with the shown letter at a rate greater than chance. They were capable of following the instructions when the letter was shown for longer . Given the chance to wager (...) low or high on their choices after short duration stimuli, participants declined to wager high even when they were correct. Taken together these results suggest that the briefly presented stimuli were processed subconsciously. (shrink)

Experimenters generally infer whether participants have visual experiences based on metacognitive responses. We showed a well-studied blindsight participant, GY, several definitions of the term “qualia” and then questioned him about whether he felt or he experienced qualia in his normal and blind fields. We found, contrary to others who have used different methods for measuring qualia, that GY does not have qualia for stationary stimuli in his blind field. This novel method for directly assessing qualia embraces the idea that experiences (...) should be related by the experiencer, not the experimenter. (shrink)

We explored whether information processed subconsciously in blindsight is qualitatively different from normal conscious processing. On each trial the blindsight patient GY was presented with a square-wave grating either in an upper or lower quadrant of his visual field and was asked to report the opposite of its location . We found that while GY was able to follow these exclusion instructions in his normal field, he tended to erroneously respond with the real location when the grating appeared in his (...) blind field. Remarkably, his error rate actually increased with increasing grating contrast in his blind field. The interpretation of these results does not rely on subjective reports and thus cannot be criticized on the grounds that subjective reports are unreliable. We conclude that blindsight is unlike normal conscious vision. (shrink)

Descriptive Experience Sampling is a clever method for determining the form of everyday thoughts. Results using this method show that people report that some of their thoughts are unsymbolic. Here I ask three questions: Does this merely show that people know what they are thinking about but not what they are thinking? Why do people have difficulty determining the form of their thoughts? How does the act of reporting the form of thoughts affect the recall of those thoughts?

Background Medical schools are grappling with how best to manage industry involvement in medical education.Objective To describe a case study of industry-supported undergraduate medical education related to opioid analgesics.Method Institutional case study.Results As part of their regular curriculum, Canadian medical students attended pain pharmacotherapy lectures that contained questionable content about the use of opioids for pain management. The lectures were supported by pharmaceutical companies that market opioid analgesics in Canada and the guest lecturer was a member of speakers bureaus of (...) the same companies. These conflicts of interests were not fully disclosed. A reference book that reinforced some of the information in the lectures and that was paid for by a sponsoring company was made available to students. This is the first report of an association between industry sponsorship and the dissemination of potentially dangerous information to medical students.Conclusions This case demonstrates the need for better strategies for preventing, identifying and dealing with problematic interactions between the pharmaceutical industry and undergraduate medical education. These might include the avoidance of unnecessary conflicts of interest, more disclosure of conflicts, an open process for dealing with recognised problems and internationally harmonised conflict of interest policies.

The question whether rights to health care should be altered by smoking behaviour involves wideranging implications for all who indulge in hazardous behaviours, and involves complex economic utilitarian arguments. This paper examines current debate in the UK and suggest the major significance of the controversy has been ignored. That this discussion exists at all implies increasing division over the scope and purpose of a nationalised health service, bestowing health rights on all. When individuals bear the cost of their own health (...) care, they appear to take responsibility for health implications of personal behaviour, but when the state bears the cost, moral obligations of the community and its doctors to care for those who do not value health are called into question. The debate has far-reaching implications as ethical problems of smokers' rights to health care are common to situations where health as a value comes into conflict with other values, such as pleasure or wealth.

The binary exclusion task involves “subtle priming effects” and a measure of awareness that is reliable, relevant, immediate, and sensitive. This task, which meets the criteria outlined in the target article, has been used to demonstrate subconscious processing.

The British Government is implementing some major alterations to the way health services in Great Britain are organised. As well as the introduction of competition between health care providers, their financial interests are to be linked to their output, in efforts to use market forces to increase efficiency and cut costs. This paper looks at the possible impact of these changes of health care organisation on ethical medical practice. This is investigated with particular reference to the country whose health service (...) has embraced most closely these elements of the market--the United States of America. The question to be answered is whether high standards of ethical care are ensured by factors somehow intrinsic to the medical profession, and are therefore immune to changes in the economics of health care. This assumption is shown to be questionable in light of what is known about the determinants of ethical medical practice. (shrink)

The fact that early visual processing has a larger capacity than later visual processing can be explained without positing distinct systems for phenomenology and cognitive accessibility. While phenomenology may overflow forced-choice reports, the later can also overestimate the former, as in the case of blindsight. Metacognitive measures of awareness offer a way to address the of consciousness research.

Currently more than half of the world’s population lives in cities. This is expected to rise to more than two-thirds by mid-century. Thus, our economic, social, and environmental challenges mostly and increasingly play out in urban settings. How can cities be strengthened to address the growing challenges they face? This special issue addresses the ethical implications of revitalizing urban environments, and the roles that diversity and inclusion, as well as social innovation, play in this process. The five papers herein show (...) that it is not easy to strengthen our cities, but with the right policies, political and corporate leadership, and depth of community grounding in ethical principles, it is possible. In this editorial essay, we summarize the contributions of each of these papers to this important conversation, clarify the questions that remain, and offer directions for future research. (shrink)

In this article we offer a single case study using an action research method for gathering and analysing data offering insights valuable to both design and research supervision practice. We do not attempt to generalise from this single case, but offer it as an instance that can improve our understanding of research supervision practice. We question the conventional ‘dyadic’ models of research supervision and outline a more collaborative model, based on the signature pedagogy of architecture: the design studio. A novel (...) approach to the supervision of creatively oriented postgraduate students is proposed, including new approaches to design methods and participatory supervision that draw on established design studio practices. This model collapses the distance between design and research activities. Our case study involving Master's Research Students supervision in the discipline of Architecture, shows how ‘connected learning’ emerges from this approach. This type of learning builds strong elements of creativity and fun, which promote and enhance student engagement. The results of our action research suggest that students learn to research more easily in such an environment and supervisory practices are enhanced when we apply the techniques and characteristics of design studio pedagogy to the more conventional research pedagogies imported from the humanities. We believe that other creative disciplines can apply similar tactics to enrich both the creative practice of research and the supervision of HDR students. (shrink)

KEY POINTS In Canada, commercial data brokers collect deidentified patient data from pharmacies, private drug insurers, the federal government and medical clinics without patient consent. Although pharmaceutical companies are the data brokers’ primary customers, academics and nonprofit and public entities also use commercial data sets, given the absence of a coordinated public approach to collecting these data across Canada. Risks of commercialized patient data include loss of anonymity, surveillance and marketing, discrimination and violation of Indigenous data sovereignty. Coordinated infrastructure for (...) the collection and coordination of health data across Canada and updated privacy legislation would protect individuals and communities and enable appropriate data uses.

A recent report by Persaud et al. [Persaud, N., McLeod, P. & Cowey, A. . Post-decision wagering objectively measures awareness. Nature Neuroscience 10, 257–261] addresses a fundamental issue in consciousness science: the experimental measurement of conscious content. The authors propose a novel technique, ‘post-decision wagering’, in which subjects place bets on the correctness of decisions or discriminations. In this note, I critique the authors’ claim that their method “measures awareness directly”.

Post-decision wagering has been proposed as a method of demonstrating that perception can occur without conscious awareness. When wagering is independent from above-chance performance there is evidence of a lack of awareness of the correctness of the first-order discriminations. However, there are reasons to believe that the contingency analysis conducted by Persaud and colleagues failed to measure “the zero accuracy-wagering criterion”. The author shows that a Pearson chi-square test employed by Persaud and colleagues is unable to accommodate the (...) hypothesis of partial independence between accuracy and advantageous wagering. On the contrary, the problem of “the zero accuracy-wagering criterion” is best conducted with log-linear models. Moreover, log-linear analysis suggests that absence of advantageous wagering is not sufficient evidence for a lack of conscious awareness. In the case of the blindsight study, there was compelling evidence that the patient GY was partially aware of having information about the correctness of his decisions. (shrink)

We all have a mind, but how much do we know about what it is, and how it works? How do philosophers, physiologists, pyschologists and psychiatrists differ in their understanding of its processes?
