Visual emotionally charged stimuli have been shown to elicit early electrophysiological responses (e.g.,
[Ihssen et al., 2007],
[Schupp et al., 2003] and [Stolarova et al., 2006]). We presented isolated words to listeners, and observed, using generalized additive modeling, oscillations in the upper part of the delta range, the theta range (Bastiaansen & Hagoort, 2003), and the lower part of the alpha range related to degree of (rated) danger and usefulness (Wurm, 2007) starting around 150 ms and continuing to 350 ms post stimulus onset. A negative deflection in the oscillations tied to danger around 250-300 ms fits well with a similar negativity observed in the same time interval for visual emotion processing. Frequency and competitor effects emerged or reached maximal amplitude later, around or following the uniqueness point. The early effect of danger, long before the words’ uniqueness points, is interpreted as evidence for the dual pathway theory of LeDoux (1996). 相似文献

Mnemonic and executive performance is encoded into activity patterns of complex neuronal networks. Lesion studies revealed that adult recognition memory critically depends on the activation of the prefrontal cortex (PFC) and hippocampus (HP). However, its developmental profile remains poorly elucidated. We previously showed the rat PFC and HP are functionally coupled in theta- and gamma-band oscillations during neonatal [postnatal day (P) 5-8] and pre-juvenile (P10-15) stages of development. Here, we assess the behavioral readout of this early prefrontal-hippocampal activation by investigating the ontogeny and the mechanisms of novelty detection and recognition memory in relationship to the functional integrity of the PFC and HP. Excitotoxic lesion of the HP at birth led to abnormal oscillatory entrainment of the PFC throughout neonatal and pre-juvenile development. Although the onset of novelty detection correlated rather with the maturation of sensory perception and motor skills than with hippocampal integrity, the pre-juvenile performance in item, spatial and temporal order recognition memory significantly decreased after HP lesion at birth. This poorer performance does result neither from abnormal developmental milestones and locomotion nor from increased anxiety. Thus, novelty recognition in rat emerges during the second postnatal week and requires functional integrity of communication within neuronal networks including the PFC and HP. 相似文献

This study explored mind-brain characteristics of successful leaders as reflected in scores on the Brain Integration Scale,
Gibbs’s Socio-moral Reasoning questionnaire, and an inventory of peak experiences. These variables, which in previous studies
distinguished world-class athletes and professional classical musicians from average-performing controls, were recorded in
20 Norwegian top-level managers and in 20 low-level managers—matched for age, gender, education, and type of organization
(private or public). Top-level managers were characterized by higher Brain Integration Scale scores, higher levels of moral
reasoning, and more frequent peak experiences. These multilevel measures could be useful tools in selection and recruiting
of potential managers and in assessing leadership education and development programs. Future longitudinal research could further
investigate the relationship between leadership success and these and other multilevel variables. 相似文献

Following on Westerståhl’s argument that many is not Conservative [9], I propose an intensional account of Conservativity as well as intensional versions of EXT and Isomorphism closure. I show that an intensional reading of many can easily possess all three of these, and provide a formal statement and proof that they are indeed proper intensionalizations. It is then discussed to what extent these intensionalized properties apply to various existing readings of many. 相似文献

‘This Is the Person You Selected’: Eyewitnesses' Blindness for Their Own Facial Recognition Decisions 下载免费PDF全文
The aim of the current research was to identify conditions under which choice blindness in facial recognition decisions occurs. In five experiments, participants watched four mock‐crime videos and made choices that were either evaluative (Experiment 1) or absolute in nature (Experiments 2a–c and 3). When participants were subsequently asked to motivate their choice, they were sometimes presented with choices they had not made. For evaluative decisions, concurrent (27%) and retrospective blindness rates (21%) were relatively low compared with previous studies. For absolute decisions, choice‐blindness rates varied, depending on when exposure to the manipulated outcome took place (immediate: concurrent 32–35%, retrospective 0–6% [Experiments 2a–c]; 48 hours' delay: concurrent 68%, retrospective 39% [Experiment 3]). We argue that blindness for facial recognition decisions is more likely for evaluative decisions and for longer intervals between decision and manipulation and also for conditions of increased task complexity, which we interpret in terms of ambiguity.

Within the German police behavioural case analysis is considered to be a further development of profiling as established in the 1980s by the American FBI. In principle behavioural case analysis is a process of systematically and analytically researching criminal cases with the aim of generating supporting leads in the search for the unknown offender. It is predominantly characterized by a critical and comprehensive reflection of methodological and criminological background knowledge and its application to the specifics of a given case. As part of a continued process of quality management the fundamental principles of North American profiling were assessed. Aspects of the logic of reconstruction and hermeneutic processes were integrated and relevant criminological research was considered or carried out where required. Also, a set of heuristic meta-rules was established. In this way a methodologically and heuristically well-founded framework was created which reduces the conflicting effects of existing habits of interpretation to a minimum and enhances the critical and creative work with hypotheses. 相似文献

Stalking is a widespread phenomenon which can be caused by different motives and in rare cases can be considered as an expression of mental illness. Stalking can occur as a symptom of schizophrenia or erotomania. The criminal culpability of psychotic stalkers is diminished and appropriate treatment has to be administered. However, there are cases which are not clearly distinct from delusional disorders. Stalking may be driven by morbid infatuation which impairs cognitive and affective capability. As the boundaries between full criminal responsibility and diminished criminal responsibility according to German penal law are blurred, these cases require thorough forensic assessment. 相似文献

Differential recall of central and peripheral details of emotional slides is not a stable phenomenon
A number of studies have reported that central information of an emotional scene is well retained, whereas peripheral details of such a scene are poorly recalled. Experiment 1 tested the hypothesis that attentional narrowing is responsible for this phenomenon. In addition, an attempt was made to increase the ecological validity of the experiment by giving extensive self-relevant instructions. Results showed that, although an emotional slide elicited eye-movements consistent with attentional narrowing, the corresponding recall patterns were absent. Experiments 2 and 3 explored some of the variables that might be responsible for the latter result. Experiment 2, relying on the original design of Christianson and E.F. Loftus (1991), found enhanced recall of central information of an emotional scene. Experiment 3 systematically varied stimulus exposure and interstimulus interval durations. However, the results of this experiment were rather complex and did not fully support the predicted differential recall patterns. Possible explanations for these findings are discussed. It is suggested that other methods (e.g. increasing levels of emotion rather than involvement) may be more suitable for testing the attentional narrowing hypothesis of emotional memory. 相似文献

Al–Pb ribbons containing 1?at.%?Pb have been produced by melt-spinning and subsequently investigated by high-resolution transmission electron microscopy. It is shown that the lattice mismatch of about 22% between the nanometre-sized Pb inclusions and the surrounding Al matrix is accommodated by a periodic array of misfit dislocations at the Al–Pb interface. The closing failures of Burgers circuits drawn around misfit dislocations on {111} and {100} facets identify the corresponding Burgers vectors as (a 0/4)? 211 ? and (a 0/2)? 110?, respectively. The Burgers vector of (a 0/4)? 211? corresponds to the projected edge part of a 60° (a 0/2)? 110? dislocation. The Pb inclusions themselves appear to be free of defects. 相似文献

The conception of man as an economic animal is implied by the view that economic production is the determining “factor” or “sphere” of man or society. Against this conception can be put another, that of man as praxis. This takes account of man as a creative being, capable of realizing his freedom through his own activity. In this article the theory of the determining role of the “economic factor”, and the theory of factors in general have been examined. The economic interpretation of history, a variant of the theory of factors, has been acknowledged as partly true for the self‐alienated man and society, but the theory of factors in any variant has been found inadequate as a general theory of man, or society. The possibility of freedom cannot be reduced to the fact that the determining roles played by “factors”, vary, or to the hope that the economic “factor” can be subordinated to a “better” one. Man's freedom consists in his resolving the conflict of “factors”, and in realizing himself as an integral creative being, no longer split into independent and mutually opposed spheres. 相似文献
