Science popularisation is widely recognised as having its ‘political uses’ and as serving as a conventional means for buttressing the epistemic authority of the institutions of science in society. By separating the work of producing new knowledge from its dissemination, popularisation promotes public understanding and appreciation of science placed beyond public reach and influence. However, simply by insisting upon such a separation, so popularisation remains vulnerable to ‘capture’ by skilled and resourceful communicators intent on turning it against the established authority of scientists. This is a phenomenon which can be analysed in relation to the communicative strategies pursued by a collection of general practitioners, diabetics and self-styled dietary experts in Sweden championing a low-carbohydrate/high fat (LCHF) dietetics akin to the Diet Revolution initiated by Robert Atkins in the early 1970s. By dedicating themselves to achieving an overwhelming public presence in the propagation of simplified accounts of dietary science, the LCHF movement has been able to fashion science popularisation into a weapon capable of being turned back upon established dietary expertise in Sweden. In this effort they have proceeded on two fronts; firstly by debunking established dietary advice for failing to live up to idealised standards of ‘sound science’, and secondly, by effectively mobilising the personal testimony and endorsements of dieters themselves in order to publicly confirm the authenticity and trustworthiness of the LCHF regimen. 相似文献

Critical realism has been used in connection with different epistemological positions. The article reviews its different uses in German, American, and British philosophy and examines its relation to Barbour's introduction of the term in the science and theology debate. The result is that there is a close connection to scientific realism, but not to philosophical critical realism in a narrower sense. Critical realism is a type of realism defining the term in Kant's sense as related to the question of the existence of the tempospatial world. It distinguishes itself as a middle way between naïve realism and other extremes. 相似文献

During rapid serial visual presentation (RSVP), the perceptual system is confronted with a rapidly changing array of sensory information demanding resolution. At rapid rates of presentation, previous studies have found an early (e.g., 150–280 ms) negativity over occipital sensors that is enhanced when emotional, as compared with neutral, pictures are viewed, suggesting facilitated perception. In the present study, we explored how picture composition and the presence of people in the image affect perceptual processing of pictures of natural scenes. Using RSVP, pictures that differed in perceptual composition (figure–ground or scenes), content (presence of people or not), and emotional content (emotionally arousing or neutral) were presented in a continuous stream for 330 ms each with no intertrial interval. In both subject and picture analyses, all three variables affected the amplitude of occipital negativity, with the greatest enhancement for figure–ground compositions (as compared with scenes), irrespective of content and emotional arousal, supporting an interpretation that ease of perceptual processing is associated with enhanced occipital negativity. Viewing emotional pictures prompted enhanced negativity only for pictures that depicted people, suggesting that specific features of emotionally arousing images are associated with facilitated perceptual processing, rather than all emotional content. 相似文献

Decision-making research has thoroughly investigated how people choose from a set of externally provided options. However, in ill-structured real-world environments, possible options for action are not defined by the situation but have to be generated by the agent. Here, we apply behavioral analysis (Study 1) and functional magnetic resonance imaging (Study 2) to investigate option generation and subsequent choice. For this purpose, we employ a new experimental task that requires participants to generate options for simple real-world scenarios and to subsequently decide among the generated options. Correlational analysis with a cognitive test battery suggests that retrieval of options from long-term memory is a relevant process during option generation. The results of the fMRI study demonstrate that option generation in simple real-world scenarios recruits the anterior prefrontal cortex. Furthermore, we show that choice behavior and its neural correlates differ between self-generated and externally provided options. Specifically, choice between self-generated options is associated with stronger recruitment of the dorsal anterior cingulate cortex. This impact of option generation on subsequent choice underlines the need for an expanded model of decision making to accommodate choice between self-generated options. 相似文献

The number of items that can be individuated at a single glance is limited. Here, we investigate object individuation at a higher temporal resolution, in fractions of a single glance. In two experiments involving object individuation we manipulated the duration of visual persistence of the target items with a forward masking procedure. The number of items as well as their stimulus–onset asynchrony (SOA) to the mask was varied independently. The results showed main effects of numerosity and SOA, as well as an interaction. These effects were not caused by a generic reduction of item visibility by the mask. Instead, the SOA manipulation appeared to fractionate the time to access the sensory image. These findings suggest that the capacity limit of 3–4 items found in object individuation is, at least partially, the consequence of the temporal window of access to sensory information. 相似文献

ABSTRACTIntegrating an interactionist model of personality development, the cumulative continuity model of personality development, and selection–evocation–manipulation theory, the present study analysed reciprocal relations of the Dark Triad common core and its sub-traits of narcissism, psychopathy, and Machiavellianism with competitive psychological climate. Moreover, within a large (N = 1,185) and longitudinal sample of employees from Germany, latent cross-lagged panel analyses were applied to analyse the moderating roles of age and organization change (i.e., organizational turnover). Overall, results revealed positive reciprocal relations between the Dark Triad common core, its sub-traits, and competitive psychological climate. The Dark Triad common core and Machiavellianism were more stable within the older (50–59 years) compared to the younger (25–34 years) age group. However, we found no age differences for the relation between competitive psychological climate and change in the Dark Triad common core or its sub-traits. Among employees who changed organizations, the Dark Triad common core, narcissism, and psychopathy were more strongly positively related to the change in competitive psychological climate than in the non-change group. This suggests stronger selection compared to evocation–manipulation effects for individuals with high values in the Dark Triad common core, narcissism, and psychopathy, but not for Machiavellianism. 相似文献
