A number of recent studies have documented rapid changes in behavioural sensory acuity induced by aversive learning in the olfactory and auditory modalities. The effect of aversive learning on the discrimination of low-level features in the visual system of humans remains unclear. Here, we used a psychophysical staircase procedure to estimate discrimination thresholds for oriented grating stimuli, before and after differential aversive learning. We discovered that when a target grating orientation was conditioned with an aversive loud noise, it subsequently led (...) to an improvement of discrimination acuity in nearly all subjects. However, no such change was observed in a control group conditioned to an orientation shifted by ±90° from the target. Our findings cannot be explained by contextual learning or sensitisation factors. The results converge with those reported in the olfactory modality and provide further evidence that early sensory systems can be rapidly modified by recently experienced reinforcement histories.

In this open peer commentary, we categorize the possible “neuroscience in national security” definitions of misuse of science and identify which, if any, are uniquely presented by advances in neuroscience. To define misuse, we first define what we would consider appropriate use: the application of reasonably safe and effective technology, based on valid and reliable scientific research, to serve a legitimate end. This definition presents distinct opportunities for assessing misuse: misuse is the application of invalid or unreliable science, or is (...) the use of reliable scientific methods to serve illegitimate ends. Ultimately, we conclude that while national security is often a politicized issue, assessing the state of scientific progress should not be. (shrink)

In Scotland, for hundreds of years, juries have chosen between three criminal verdicts: “guilty,” “not guilty,” and “not proven.” The “not proven” verdict’s legal meaning remains mysterious. In this article, I aim to describe and solve the problem. Applying modern ideas about standards of proof to the intellectual history of “not proven” yields eight plausible meanings for the verdict. With the extent of the problem in mind, I offer a solution. In the three-verdict system, jurors should deliver a “guilty” verdict (...) when they believe that the accused has committed the crime and a “not guilty” verdict when they believe that the accused has not committed the crime. The “not proven” verdict is for all other states of mind. Clarifying this question matters for determining whether the verdict’s existence is just. It also offers some evidence for how the criminal standard of proof works in other legal systems. (shrink)

This collection cuts across conventional disciplinary boundaries to address the roles, responsibilities, and regulation of contemporary lawyers. Contributors address common concerns from diverse perspectives, including philosophy, psychology, economics, political science, and organisational behaviour. Topics include the nature of professions, the structure of practice, the constraints of an adversarial system, the attorney-client relationship, the practical value of moral theory, the role of race and gender, and the public service responsibilities of lawyers and law students.

She concentrates on responses to the 'crisis' that currently confronts the American legal profession and legal education—including the increasing cost of legal services, the threat to lawyer income and the oversupply of law graduates. Rhode regards the response by the American Bar Association (ABA) through its Ethics 20/20 Commission as lacking innovation and achieving only modest reform. Surveying other countries' efforts at opening the provision of some traditional legal services to non-lawyers and outside investment in law practices, she argues that (...) the US 'is likely to lag behind other nations in its capacity to provide cost effective legal services'. She also proposes greater diversity in the options available for legal education. (shrink)
