Google Books Ngram was used to assess changes in frequency of usage in words corresponding to collectivistic and individualistic values in Russia during the time of economic changes. It was found that in many domains transition to market economy was associated with a rise in the use of words corresponding to individualistic values and a decrease in the use of words associated with collectivistic values. In several cases, words corresponding to collectivistic terms were used more often than words corresponding to individualistic values. The results suggest that economic changes lead to a change in values structure, but that individualistic and collectivistic values can co‐exist because of the transitional sate of the Russian society. 相似文献
Siblings of children with autism spectrum disorders (ASD) present greater susceptibility to developmental problems, in comparison with siblings of typically developing children. The greater prevalence of mental health disorders among parents of children with ASD increases younger siblings’ vulnerability to emotional problems. The aim of this study is to compare the interaction between carers and babies aged 2 to 26 months (M = 11.7, SD = 6.9) who are siblings of children with ASD (ASD dyads) with the interaction of dyads of siblings of typically developing children (TD dyads). The protocol of Clinical Indicators of Risk for Child Development and the Coding Interactive Behaviour measures were used to evaluate interaction. ASD dyads presented higher scores of constriction in their interaction, P = .024, with babies presenting higher scores of withdrawal behavior, P = .003, and carers presenting higher scores of depressive mood, P = .008, when compared to TD dyads. The ASD dyads have interactive impairments more frequently than do the TD dyads. 相似文献
The paper argues that Nikolai Berdyaev’s doctrine of theurgy has remained relevant in today’s cultural-historical context because it highlights a continuing problem in the philosophy of art. The problem is the misunderstanding of the ludic nature of art, its role in the evolution of consciousness and transformation of reality. The author questions the idea that artistic play is deficient compared with religious expression. As a result of this critique, he proposes that the theurgic quest for a radically new form of creativity was misguided and that the true meaning of the aspiration behind it is the need to comprehend culture as a dialectically articulated integral system of the cultural forms that constitute it.
Contingent negative variation (CNV) topography, hemispheric asymmetry and time-course were investigated in healthy subjects and non-medicated paranoid schizophrenic patients in two antisaccade paradigms with the short (800-1000 ms) and long (1200-1400 ms) durations of the fixation period. EEG and electrooculogram (EOG) were recorded. Saccade characteristics and mean amplitudes of slow cortical potentials time-locked to peripheral target were analyzed in 23 healthy volunteers and 19 schizophrenic patients. Compared to healthy control subjects, schizophrenic patients had significantly slower antisaccades and committed significantly more erroneous saccades in the both antisaccade tasks. The prolongation of the fixation period resulted in noticeable decrease of error percent in patients group. The analysis of CNV time-course has revealed two distinct stages in both groups. The early CNV stage was represented by a negative wave with the maximal amplitude over midline fronto-central area, and the late stage was characterized by increased CNV amplitude at the midline and left parietal electrode sites. In healthy subjects the simultaneous activation of frontal and parietal areas was observed in the paradigm with the shorter fixation interval; the increase of the fixation period produced consecutive activation of these areas. Schizophrenic patients' CNV amplitude was generally smaller than that of healthy subjects. The most pronounced between-group differences of the negative shift amplitude were revealed at frontal electrode sites during the early CNV stage in both modifications of the antisaccade task. The deficit of frontal activation revealed in patients at the early stage of antisaccade preparatory set in both antisaccadic paradigms may be related to pathogenesis of paranoid schizophrenia. 相似文献
The positive youth development (PYD) perspective emphasizes that thriving occurs when individual ?context relations involve the alignment of adolescent strengths with the resources in their contexts. The authors propose that a key component of this relational process is the strength that youth possess in the form of self-regulatory processes; these processes optimize opportunities to obtain ecological resources that enhance the probability of PYD. They use the selection, optimization, and compensation (SOC) model of intentional self-regulation to discuss the role of self-regulation in the PYD perspective among diverse youth. 相似文献
We studied contrast and assimilation in three tasks: an exemplar-production task, a categorization task, and a combined categorization-then-production task. On each trial of the first task, subjects produced a circle when prompted with a category label. In the second task, they classified lines that differed in length into one of four categories. On each trial of the combined task, they classified two lines and then produced a line when prompted by a category label. All three tasks converged on the same conclusion: subjects' representation of the categories (measured in pixels in the production tasks and by the direction of errors in classification) shifted systematically from trial to trial. When successive stimuli were from the same category, the representation of that category was pulled toward the exemplar from the previous trial. When successive stimuli were from different categories, the representations of the neighbouring categories were pushed from the category of the initial stimulus. We conclude that accounts of categorization and identification must accommodate both assimilation and contrast as a function of trial-to-trial shifts in representation. 相似文献
Misery is not miserly: Sadness increases the amount of money that decision makers give up to acquire a commodity. The present research investigated when and why the misery-is-not-miserly effect occurs. Drawing on William James's concept of the material self, we tested a model specifying relationships among sadness, self-focus, and the amount of money that decision makers spend. Consistent with our Jamesian hypothesis, results demonstrated that the misery-is-not-miserly effect occurs only when self-focus is high. That is, self-focus moderates the effect of sadness on spending. Moreover, mediational analyses revealed that, at sufficiently high levels, self-focus mediates (explains) the relationship between sadness and spending. Because the study used real commodities and real money, the results hold implications for everyday decisions, as well as implications for the development of theory. For example, economic theories of spending may benefit from incorporating psychological theories -- specifically, theories of emotion and the self -- into their models. 相似文献
There is limited information on mental health of psychologists and social workers despite their rendering mental health services, so their subjective perception of mental disorder was explored via a self-evaluation survey in which they self-diagnosed the presence of DSM-IV disorders within themselves. The sample of 128 professionals included 63 psychologists and 65 social workers. The presence of Axis I traits was reported by 81.2%, the three most frequent traits being mood, obsessive-compulsive disorder, and eating disorder. Axis II traits were reported by 73.4% of subjects, the three most frequent conditions being narcissistic, avoidant, and obsessive-compulsive personality traits. While a high percentage of subjects reported the presence of either an Axis I or Axis II disorder, the average severity reported was low. More psychologists reported on mood, social phobia, and eating problems than social workers, while the latter reported more on psychotic problems. Psychologists reported more Axis II traits, especially paranoid, narcissistic, and avoidant subtypes. More women than men reported eating problems, while more men reported schizoid and avoidant personality traits. In conclusion, manifestations of subthreshold psychiatric conditions were prominently reported. These findings suggest encouraging mental health care professionals to explore treatment for problems if present. 相似文献
