This article provides an overview of recent developments in solving the timing problem (discreteness vs. continuity) in cognitive neuroscience. Both theoretical and empirical studies have been considered, with an emphasis on the framework of operational architectonics (OA) of brain functioning (Fingelkurts and Fingelkurts in Brain Mind 2:291-29, 2001; Neurosci Biobehav Rev 28:827-836, 2005). This framework explores the temporal structure of information flow and interarea interactions within the network of functional neuronal populations by examining topographic sharp transition processes in the scalp EEG, on the millisecond scale. We conclude, based on the OA framework, that brain functioning is best conceptualized in terms of continuity-discreteness unity which is also the characteristic property of cognition. At the end we emphasize where one might productively proceed for the future research. 相似文献

Boredom is a common experience in healthy individuals and may be elevated in various neurological or psychiatric conditions. As yet, very little is known about the cognitive or neural bases of the subjective experience of boredom. We examined temporal perception and the temporal allocation of attention in healthy individuals reporting high- or low-levels of boredom. We found no difference in high- or low-boredom-prone individuals in the temporal allocation of attention, while individuals who experienced low-levels of boredom tended to underestimate time more so than high-boredom-prone individuals. Furthermore, high-boredom-prone individuals demonstrated higher error values when estimating time indicating that the subjective perception of the passage of time may be a critical component to the experience of boredom. 相似文献

The need to establish a borderline between legitimate and illegitimate political trial is one of the central societal discourses.
In this paper the author claims that the issues are complex and that a political trial can remain legitimate as long as it
is not dealing with a confrontation with the symbolic order on which the society (and the court itself) is founded and as
long as the subject (or action) it is dealing with does not threaten the symbolic order’s (or the “Big Other”) existence.
When the symbolic order’s existence is in danger, the court is bound to participate in an act of “sacrifice” that is intended
to protect the “order.” The author uses Jacques Lacan’s psychoanalytic theory of the “Big Other” (and its development to ideological-political
terms) in examining three categories of sacrifice. Through these categories the author claims that in extreme cases of confrontation
with the existence of the symbolic order, the court cannot remain objective and it would be difficult to justify the trial
as legitimate (especially in historical perspective). 相似文献

Effects of emotional valence on attention have been shown to occur even when stimuli are presented outside awareness. The impact of negative valence on stimulus processing has been demonstrated to be particularly salient in anxiety. Therefore, it has been hypothesized that compared to nonanxious individuals, anxious individuals have an enhanced ability to detect the valence of negative stimuli. However, it remains unclear whether anxious individuals are better at identifying the valence of threatening stimuli or, rather, more likely to label ambiguous stimuli as threatening. To investigate these hypotheses, high and low anxious participants categorized lexical stimuli as "safe" or "dangerous." Stimuli were presented at durations that allowed for both conscious (unmasked) and nonconscious (masked) processing. Results show that on masked trials, anxious individuals evidenced an enhanced ability to correctly classify threatening information, whereas nonanxious participants demonstrated an enhanced ability to correctly classify neutral or positive information. Signal detection analyses indicated results were explained by a response bias, whereby anxious individuals were more likely than nonanxious individuals to categorize masked words as threatening and nonanxious individuals were more likely to categorize masked words as nonthreatening. No group differences for nonword stimuli emerged, suggesting that anxiety-related response bias tendencies are activated only after detection of a weak semantic signal. 相似文献

The paper justifies the concept of “thematic structure” or “order of knowledge” over the traditional “classification of sciences”
due to the uncertainty of many classification criteria. The thematic structure of science has, of course, various levels and
various dimensions. Arguments against any forms of separating the humanities from sciences in the traditional sense of the
term are presented and discussed. Equally unacceptable are attempts at sharp separation of technical disciplines and humanities.
The thematic structure of humanities is not created by some material aspects but rather through the interest — or problem-oriented
aspects. In addition to the natural sciences and the humanities there exists an important sphere of sciences on artefacts
or, using the term by H. Simon, the sciences of the artificial. For the contemporary research activities is typical what could
be denoted as “interdisciplinary or multidisciplinary complex.” The paper traces a set of epistemological criteria for the
justification of the relative independence of a scientific discipline.

The use ofp-values in combining the results of independent studies often involves studies that are potentially aberrant either in quality or in actual values. A robust data analysis suggests the use of a statistic that takes these aberrations into account by trimming some of the largest and smallestp-values. We present a trimmed statistic based on an inverse cumulative normal transformation of the orderedp-values, together with a simple and convenient method for approximating the distribution and first two moments of this statistic.The author thanks Ingram Olkin, David Rogosa, Jim Hodges and two anonymous reviewers for providing many useful comments and suggestions. 相似文献

时间顺序信息加工的实验研究 总被引:8,自引:2,他引:6
该研究运用Glucksberg和McCloskey(1981)的问答模型,通过两个实验检查了项目的时序信息是通过项目学习时的时序编码获得的,还是在项目提取时建构的;时序加工是自动的,还是控制的两个问题。结果表明:项目的时序信息是通过项目学习时的时序编码获得的,而不是在项目提取时建构的;时序信息的编码是控制的。 相似文献
