Following Hans Blumenberg and others, an account is given of the coming about of Modernity and of its major characteristics. The aim of the paper is to show that, from the very beginning, a restricted number of philosophical reactions are developed towards the phenomenon of Modernity. These reactions are represented in the major ‘modern’ philosophers: Descartes, Spinoza, Hume (and Kant) and French Enlightenment thinkers (as, e.g., Condorcet). These major reactions repeat themselves mutatis mutandis well into the 20th century. The paper ends with a brief discussion of the possibility of (modern) metaphysics at the present moment. 相似文献

School professionals need to be prepared to support children with emotional and behavioral problems. Teachers in particular
should be aware of the resources provided by their school as well as the evidence-based practices available to support children
with behavioral problems. This study explored general education teachers’ knowledge of 10 evidence-based interventions as
well as resources and data collected at their schools to support children with mental health problems. Participants included
239 general educators from 5 school districts. Overall, most teachers had not heard of 9 out of 10 of the evidence-based programs
presented. Teachers were also not sure whether their schools provided specific assessments and interventions to support children.
One particularly noteworthy finding was that 57% of teachers were not sure whether their schools provided functional behavioral
assessment and intervention planning. Findings illuminate a need for continued work in this area. 相似文献

ABSTRACT A digital pursuit rotor task was used to measure dual task costs of language production by young and older adults. After training on the pursuit rotor, participants were asked to track the moving target while providing a language sample. When simultaneously engaged, young adults experienced greater dual task costs to tracking, fluency, and grammatical complexity than older adults. Older adults were able to preserve their tracking performance by speaking more slowly. Individual differences in working memory, processing speed, and Stroop interference affected vulnerability to dual task costs. These results demonstrate the utility of using a digital pursuit rotor to study the effects of aging and dual task demands on language production and confirm prior findings that young and older adults use different strategies to accommodate to dual task demands. 相似文献

This paper highlights a symposium on stress risk factors and stress susceptibility, presented at the Neurobiology of Stress workshop in Boulder, CO, in June 2010. This symposium addressed factors linking stress plasticity and reactivity to stress pathology in animal models and in humans. Dr. J. Radley discussed studies demonstrating prefrontal cortical neuroplasticity and prefrontal control of hypothalamo-pituitary-adrenocortical axis function in rats, highlighting the emerging evidence of the critical role that this region plays in normal and pathological stress integration. Dr. M. Kabbaj summarized his studies of possible epigenetic mechanisms underlying behavioral differences in rat populations bred for differential stress reactivity. Dr. L. Jacobson described studies using a mouse model to explore the diverse actions of antidepressants in brain, suggesting mechanisms whereby antidepressants may be differentially effective in treating specific depression endophenotypes. Dr. R. Yehuda discussed the role of glucocorticoids in post-traumatic stress disorder (PTSD), indicating that low cortisol level may be a trait that predisposes the individual to development of the disorder. Furthermore, she presented evidence indicating that traumatic events can have transgenerational impact on cortisol reactivity and development of PTSD symptoms. Together, the symposium highlighted emerging themes regarding the role of brain reorganization, individual differences, and epigenetics in determining stress plasticity and pathology. 相似文献

We evaluated the effects of a dense (fixed-ratio 1) schedule of reinforcement for an 11-year-old boy's mands for toys while aggression produced the same toys on various schedules chosen on the basis of a progressive-ratio probe. Based on the probe session data, we accurately predicted that aggression would be more probable than mands when the schedules were equal or slightly discrepant, but that mands would be more probable when the schedule discrepancy was large. 相似文献

One of the fundamental properties of spatial vision is the ability to localize objects in space. According to a recent proposal,
accurate localization performance involves the operation of two systems: the attention system and the eye movement system.
Upon stimulus presentation, attention is shifted to the target area: this provides coarse location information. Subsequently,
a saccadic eye movement is executed: this provides fine location information. In this study we tested predictions derived
from this model concerning the effects of precue information on localization performance. In a series of five experiments
we manipulated duration of precue (71, 400, and 1,000 ms) and type of precue (spatial versus symbolic). Results showed that
very short duration (i.e., 71 ms) spatial precues improved localization performance whereas very short duration symbolic precues
did not. In contrast, the 1,000 ms duration precue condition showed similar amounts of precuing benefit for the spatial and
symbolic precues. This pattern of differential precuing effects corroborated the two-process model of localization performance.

Lack of the metabotropic glutamate receptor subtype 7 selectively modulates Theta rhythm and working memory 下载免费PDF全文

Metabotropic glutamate receptors (mGluRs) are known to play a role in synaptic plasticity and learning. We have previously shown that mGluR7 deletion in mice produces a selective working memory (WM) impairment, while other types of memory such as reference memory remain unaffected. Since WM has been associated with Theta activity (6-12 Hz) in EEGs, and since EEG abnormalities have been observed in these mice before, we studied the effect of mGluR7 gene ablation on EEG activity in the hippocampus, in particular in the Theta range, during performance of a WM task. In an eight-arm maze with four arms baited, mGluR7 knock-out (KO) and wild-type mice committed the same number of reference memory errors, whereas KOs committed more WM errors. While performing the task, KO mice showed substantially higher Theta amplitudes, and the ratio of Theta to overall EEG power was much increased. No change was seen in the Delta (0-5 Hz), or Gamma (30-40 Hz) EEG bands compared with controls. When recording EEGs during periods of rest in the home cages, no difference was seen between groups. These findings suggest that mGluR7 is important for modulation and control of Theta activity. Since only WM was affected, and only the Theta range of EEG activity was altered, these results show a correlation between Theta rhythm and WM performance, and therefore support the concept that Theta activity in the hippocampus is involved in WM storage. 相似文献

The authors review the effect of the presence of others on food intake. In social facilitation studies, people tend to eat more in groups than when alone. In modeling studies, the presence of others may facilitate or inhibit intake, depending on how much these other people eat. Studies of impression management demonstrate that people tend to eat less in the presence of others than when alone. The authors attempt to reconcile these divergent literatures by reference to a model of inhibitory norms that govern eating. In the presence of palatable food, and in the absence of clear signals of satiety, people look outward to cues from the environment to determine when to stop eating. Socially derived inhibitory norms can account for either increased or decreased intake in the presence of others, depending on how much the others eat and the extent to which one is eager to impress them. 相似文献
