Abstract: Critics charge that retributivists fail to show why the state should concern itself with ensuring that criminal offenders are punished in accordance with their ill deserts. Drawing on the notion that the state should attempt to equalize the realization of the interests designated by rights, it is argued that legal punishment restores the equality of condition, disrupted by criminal conduct, that all citizens are entitled to. While this equality of condition might be restored in various ways, it is argued that the imposition of punitive losses is the most appropriate way to restore it in most cases. An account of the ill deserts of offenders, as a function of the harms their crimes produce and the extent of their culpability for those harms, is briefly elaborated. 相似文献

Knowing when to persevere with a plan and knowing when to ditch it and change strategy is highly adaptive and breaks down in several frontal and striatal disorders. Cognitive flexibility is also susceptible to tonic influences of neuromodulators (such as dopamine) and so may be influenced by everyday fluctuations in processes known to depend upon them (such as motivation). The current study employed an attentional shifting paradigm to examine the influence of changes in food-related motivational state in healthy volunteers. Hunger was induced through fasting (physiological manipulation) or through the presentation of appetitive food cues prior to testing (desire manipulation). The desire manipulation produced a stronger effect than fasting by inducing errors when participants were attempting to shift. The results suggest that everyday fluctuations in appetite and desire can produce a significant impact on cognition, highlighting implications for our understanding of excessive motivational control including maladaptive eating behaviour. 相似文献

We examined the relationship between executive functions and both factual and conceptual learning of science, specifically chemistry, in early adolescence. Sixty‐three pupils in their second year of secondary school (aged 12–13 years) participated. Pupils completed tasks of working memory (Spatial Working Memory), inhibition (Stop‐Signal), attention set‐shifting (ID/ED), and planning (Stockings of Cambridge), from the CANTAB. They also participated in a chemistry teaching session, practical, and assessment on the topic of acids and alkalis designed specifically for this study. Executive function data were related to (1) the chemistry assessment which included aspects of factual and conceptual learning and (2) a recent school science exam. Correlational analyses between executive functions and both the chemistry assessment and science grades revealed that science achievements were significantly correlated with working memory. Linear regression analysis revealed that visuospatial working memory ability was predictive of chemistry performance. Interestingly, this relationship was observed solely in relation to the conceptual learning condition of the assessment highlighting the role of executive functions in understanding and applying knowledge about what is learned within science teaching. 相似文献

abstract Supermax prisons subject inmates to extreme isolation and sensory deprivation for extended periods of time. Crime reduction and retributive arguments in favour of supermax confinement are elaborated. Both types of arguments are shown to falter once the logic of the two approaches to the justification of legal punishment is made clear and evidence about the effects of supermax confinement on inmates is considered. It is also argued that many criminal offenders suffer from defects in their capacities for morally responsible action, lack sufficient opportunities to remain law‐abiding, or are understandably alienated from society and the prison regime. The implications of this more realistic picture of offenders for supermax confinement are then explored briefly. 相似文献

Research has shown that adults can engage in cognitive offloading, whereby internal processes are offloaded onto the environment to help task performance. Here, we investigate an application of this approach with children, in particular children with poor working memory. Participants were required to remember and recall sequences of colors by placing colored blocks in the correct serial order. In one condition the blocks were arranged to facilitate cognitive offloading (i.e., grouped by color), whereas in the other condition they were arranged randomly. Across two experiments (total N = 166) the ordered condition improved task performance for children with low working memory ability. In addition, participants in Experiment 2 rated the difficulty of the two arrangements and performed a further condition in which they were given an opportunity to freely arrange the blocks before completing the task. Despite performing better in the ordered condition, children with low working memory ability did not rate the ordered arrangement as easier, nor did they choose an ordered arrangement when given the opportunity to do so. This research shows that cognitive offloading can also be a useful process in populations other than typical adults, and the implications of this work for supporting children with poor working memory are discussed. 相似文献
