This past week week I attended the International Neuroethics Society’s (INS) annual conference in San Diego, California. Neuroethics is multidisciplinary field that grapples with the implications of neuroscience for—and from—medicine, law, philosophy, and the social sciences. One of the many excellent panels brought together scholars from each of these four disciplines to discuss the diverse approaches to the field. The panel featured; Paul Appelbaum, a Professor of Psychiatry at Columbia University; Tom Buller, Chair of philosophy at Illinois State University; Jennifer Chandler, Professor of law at the University of Ottawa, and; Ilina Singh, Professor of Neuroscience & Society at the University of Oxford.
The panel started by considering the importance of the “competing identities” present in the field of neuroethics. As moderator Eric Racine explained, right from the start, even the term ‘neuroethics’ suggests a tension. Consider the variety of research methodologies employed in the field. For instance, a scholar trained in philosophy might approach neuroscience from a conceptual and purely analytical basis, and yet a social scientist might research the same question by collecting empirical interview data. The interplay between empirical and theoretical work was a theme that defined the discussion.
A psychiatrist by training, Dr. Applebaum spoke on the medical approach to the field. He argued that a focus on ethical issues in clinical psychiatry and neurology should be viewed as a part (but only a part) of neuroethics. Furthermore, medicine’s empirical approach to neuroethics is one (but not the only) way to advance thinking on neuroethical issues. Continue reading →
I recently saw someone walk into a signpost (amazingly, one that signalled ‘caution pedestrians’); by the angle and magnitude that his body rebounded, I estimated that this probably really hurt. What I had witnessed was a danger of walking under the influence of a smart phone. Because this man lacked the ability to tweet and simultaneously attend to and process the peripheral visual information that would enable him to avoid posts, the sidewalk was a dangerous place. If only there existed some way to enhance this cognitive ability, the sidewalks would be safer for multi-taskers (though less entertaining for bystanders).
In a public event on neurogaming held last Friday as part of the annual meeting of the International Society for Neuroethics, Adam Gazzaley from UCSF described a method that may lead to just the type of cognitive enhancement this man needed. In a recent paper published in nature, his team showed that sustained training at a game called NeuroRacer can effectively enhance the ability of elderly individuals to attend to and process peripheral visual information. While this game has a way to go before it can improve pedestrian safety, it does raise interesting questions about the future of our regulations surrounding distracted driving, e.g., driving while texting. In many jurisdictions, we prohibit texting while driving, and a California court recently ruled to extend these regulations to prohibit certain instances of driving under the influence of smart phones (i.e. smart driving).
But if individuals were to train on a descendant of NeuroRacer and improve their ability to visually multitask, should we give them a permit to text while driving?
