Previous research has consistently found that unsociability is linked to adjustment difficulties in Chinese children. However, far less attention has been paid to how parents and peers react when confronted with unsociable children. In this study, we explored the longitudinal linkages among Chinese preschoolers' unsociability, maladaptive parenting, and peer exclusion. Participants were mothers and teachers of N = 391 (Mage = 4.4 years, SD = 0.91 years; 54.5% boys) preschoolers attending eight kindergartens in Shanghai, People's Republic of China, followed over 8 months. Multi-source assessments were employed. Mothers rated children's unsociability and their maladaptive (physical hostility, verbal hostility, punishment) parenting practices, and teachers rated children's peer exclusion at each time point. Our results indicated that child unsociability contributed to later increases in both maladaptive parenting and peer exclusion. However, maladaptive parenting and peer exclusion could not predict later increases in unsociability. Results are discussed in terms of the implications of unsociability among Chinese children.  相似文献

依恋对象的敏感性回应是儿童安全依恋发展的重要前因。研究采用改编版依恋预期范式考察实时互动情境中依恋对象确定性和概率性回应对幼儿支持提供预期及预期修正的影响。结果发现:相对不安全型依恋幼儿,初始预期中安全型幼儿更多预期依恋对象会向依恋者提供支持;幼儿能够基于依恋对象的确定性和概率性回应一致地修正对该对象是否提供支持的预期。同时,低水平回应对幼儿预期修正的影响高于高水平回应。研究表明5岁左右幼儿能够基于实时互动中依恋对象的回应信息修正其对该依恋对象的预期,这对理解幼儿依恋表征的发展具有重要启示。  相似文献

Emergent research identifies cultural tightness-looseness as an important factor for understanding cross-national outcome differences during the coronavirus pandemic. Because perceived tightness-looseness can be measured as an individual-level difference rather than a nation-level difference, and because tightness-looseness may shift during large-scale crises, we investigated whether such shifts occurred early in the coronavirus pandemic in both China (a relatively tight nation, n = 3642) and the U.S. (a relatively loose nation, n = 3583) across three cohorts. Tightness increased across cohorts in China and reduced across cohorts in the U.S. These changes transmitted corresponding indirect effects whereby compliance and institutional trust (scientific and government) about the pandemic were increased in China across cohorts, but decreased in the U.S. across cohorts. These patterns extend advice that national governments can increase compliance and trust via “tightening” by cautioning against norm-setters signaling the reverse (that norms about compliance are loose) given the outcomes observed in the U.S. samples.  相似文献

Polydipsia induced in the rat by a second-order schedule   总被引:2,自引:2,他引:0       下载免费PDF全文
Drinking was studied in rats pressing a bar on a second-order schedule in which every third completion of a 1-min fixed interval was followed by food presentation. A brief flash of light signaled the completion of each fixed-interval component. The rats drank not only after the food presentations but also after presentations of the light flash alone. A high rate of steady drinking followed intervals terminated by a food presentation. Drinking that followed intervals terminated by a light flash alone was of comparable rate, but characteristically interrupted by bar pressing. When 250-mg food pellets were used instead of 45-mg pellets, both drinking and bar-pressing rates increased substantially.  相似文献

Using the probe-signal method, frequency-response characteristics were obtained for four Os detecting signals nominally of only 1000Hz under three signal-amplitude conditions: E/No=10.0, 12.6, and 15.8. Detection of 1000-Hz signals decreased systematically with signal-amplitude decreases, but signals at 850 Hz and at 1150 Hz were detected at or near the chance level during all signal-amplitude conditions. From the detection performance data, the detectability was inferred for four probe-signal frequencies relative to that of 1000-Hz signals for each of the amplitude conditions. From the curvesofrelative detectability, hal[-detectability bandwidths were estimated. Neither the relative detectability curves nor the half-detectability bandwidths indicate any systematic change in the frequencyselectivebehavior of the auditory O across the signal amplitudes used.  相似文献

During the years of 1981 and 1982, 89 former prisoners of the Auschwitz-Birkenau concentration camp responded to questionnaires on mussulmen-prisoners in the extreme phase of starvation disease. In this article, I describe the origin of the term "mussulman," mussulmens' somatic and mental state, their behavior and camp customs. Prisoners characterized as mussulmen remain between life and death, without expressing emotional reactions and defense mechanisms apart from a hypersensibility to food-related stimuli. A mussulman was a product of the camp factory of death. A deep somatic and emotional stigma remains in those who survived the mussulmen state.  相似文献
