The purpose of this cross-sectional study was to examine the developmental trajectory of creative potentials of Polish students. A total of 1,522 Polish students aged between 7 and 18 from lower and upper primary school, middle school, and high school participated in the study. Creative potential was measured by means of the Test for Creative Thinking-Drawing Production. The findings showed that older students achieved higher scores than the younger ones, drops in mean scores among students aged 13 and 16 were noted, and levelling of scores was found among students aged from 10 to 13, with a slight drop at the age of 13. Moreover, a phenomenon was discovered which was described as a mini plateau, i.e., an emergence of similar mean scores in 2 consecutive age groups. Possible explanations of the results are discussed, including interpretations in the context of the CMC and educational and environmental conditions which act as inhibitors or stimulators of the development of creative abilities. 相似文献
The present study reports two experiments in which a total of 20 participants without prior flight experience practiced the final approach phase in a fixed-base simulator. All participants received self-controlled concurrent feedback during 180 practice trials. Experiment 1 shows that participants learn more quickly under variable practice conditions than under constant practice conditions. This finding is attributed to the education of attention to the more useful informational variables: Variability of practice reduces the usefulness of initially used informational variables, which leads to a quicker change in variable use, and hence to a larger improvement in performance. In the practice phase of Experiment 2 variability was selectively applied to some experimental factors but not to others. Participants tended to converge toward the variables that were useful in the specific conditions that they encountered during practice. This indicates that an explanation for variability of practice effects in terms of the education of attention is a useful alternative to traditional explanations based on the notion of the generalized motor program and to explanations based on the notions of noise and local minima. 相似文献
How can shared music preferences create social bonds between people? A process model is developed in which music preferences as value-expressive attitudes create social bonds via conveyed value similarity. The musical bonding model links two research streams: (a) music preferences as indicators of similarity in value orientations and (b) similarity in value orientations leading to social attraction. Two laboratory experiments and one dyadic field study demonstrated that music can create interpersonal bonds between young people because music preferences can be cues for similar or dissimilar value orientations, with similarity in values then contributing to social attraction. One study tested and ruled out an alternative explanation (via personality similarity), illuminating the differential impact of perceived value similarity versus personality similarity on social attraction. Value similarity is the missing link in explaining the musical bonding phenomenon, which seems to hold for Western and non-Western samples and in experimental and natural settings. 相似文献
When people synchronize taps with isochronously presented stimuli, taps usually precede the pacing stimuli [negative mean
asynchrony (NMA)]. One explanation of NMA [sensory accumulation model (SAM), Aschersleben in Brain Cogn 48:66–79, 2002] is that more time is needed to generate a central code for kinesthetic-tactile information than for auditory or visual stimuli.
The SAM predicts that raising the intensity of the pacing stimuli shortens the time for their sensory accumulation, thereby
increasing NMA. This prediction was tested by asking participants to synchronize finger force pulses with target isochronous
stimuli with various intensities. In addition, participants performed a simple reaction-time task, for comparison. Higher
intensity led to shorter reaction times. However, intensity manipulation did not affect NMA in the synchronization task. This
finding is not consistent with the predictions based on the SAM. Discrepancies in sensitivity to stimulus intensity between
sensorimotor synchronization and reaction-time tasks point to the involvement of different timing mechanisms in these two
tasks. 相似文献
Self-humanization is defined as the tendency to view oneself as more essentially human than others. Researchers have claimed that people attribute human nature traits more strongly to themselves than to others, but not uniquely human traits. In this article we suggest that such claims are based on the misinterpretation of results. Most studies have not presented mean comparative judgments, making it impossible to determine whether people thought they possessed characteristics less strongly or more strongly than the average person. We found that people (N = 256) in Poland, Italy, and Korea perceived themselves as possessing desirable human nature and uniquely human characteristics more than others, as possessing undesirable uniquely human traits less than others, and as similar to others in terms of undesirable human nature characteristics. It seems that being more human than others means possessing some traits more than others and possessing some traits less than others. 相似文献
Cognitive deficits in depression are mostly apparent in executive functions, especially when integration of information and reasoning is required. In parallel, there are also numerous studies pointing to the frontal alpha band asymmetry as a psychophysiological marker of depression. In this study, we explored the role of frontal alpha asymmetry as a potential factor explaining the cognitive problems accompanying depression. Twenty-six depressed and 26 control participants completed a reasoning task and underwent 5 minutes of electroencephalography recording. In line with the previous studies, depressed people showed difficulties with reasoning but we did not observe the relationship between frontal asymmetry in the alpha band and depression. However, we found that in the depressed group the frontal alpha asymmetry index was characterised by larger variance than in the control group, and it was also a strong predictor of cognitive functioning exclusively in the depressed group. Our results point to the disruption of a psychophysiological balance, reflected in changed frontal alpha asymmetry (into more left-sided frontal asymmetry in the alpha band, reflecting more right-sided cortical activity) as a possible brain correlate of cognitive disturbances present in depressive disorders. 相似文献
This study is an attempt to reconstruct and sum up philosophical interpretations of Stavrogin, the main hero of the classic
Dostoevsky’s novel “The Devils”, given by the outstanding Russian religious thinkers in the twentieth century. The author
emphasizes that, however different can be their philosophical premises, the discussed interpretations of Dostoevsky’s hero
are compatible and complementary. Confronting and, above all, synthesizing different points of view, he tries to grasp the
basic historiosophical, anthropological and religious ideas of Russian renaissance. 相似文献
In his texts, Józef Tischner (1930–2000) referred to significant problems characteristic of the end of the communist regime and the first years of the liberal-democratic system in Poland. He tried to understand, among other things, the sources of Polish society’s disappointment with their regained political and economic freedom. This article discusses the late period of Tischner’s life and work, when his philosophy was heavily influenced by the ideas of Charles Taylor. On the one hand, the author analyzes Tischner’s attitude toward the concept of ordinary life, while on the other, Tischner’s understanding of solidarity combined with the concept of the spirit of capitalism. The article shows numerous similarities and significant differences between the way of thinking of both philosophers. The former concern above all the consentaneous assessment of the disappearance of heroism in liberal-democratic societies, while the latter concern the discrepancies in the assessment of the possibility of fully implementing the idea of solidarity in these societies.
