An intergroup sensitivity effect (ISE) is people's tendency to react more negatively to a criticism when it was made by an outgroup member than when the same criticism was made by an ingroup member. The present study investigated variation in ISE when the criticism was varied in terms of valence (absence of positive qualities or presence of negative qualities) and level of abstraction (traits or behaviours). Dependent measures were emotional reactions to the criticism, perceived constructiveness, ingroup bias, and recognition memory for the criticism. All participants showed an ISE to the negative abstract criticism. In addition, consistent with the social identity account of ISE, participants' levels of identification with their ingroup moderated the ISE in some of the measures. 相似文献

随着循证医学在我国的发展和"医疗举证责任倒置"等相关法律的实施,我国临床医生在进行诊治决策时已逐步向临床科学决策迈进。而防御性医疗、不健全的医疗制度及相关法律等却严重影响着这一科学决策的转变过程。只有有效解决了导致干扰科学决策的各种社会影响因素,如扩大基本医疗保险的覆盖率,实施医疗风险保险制度,提高医务人员认知和职业素质,保障行医安全等,临床科学决策的真正落实就大有希望。 相似文献

探讨如何提高急性白血病患者染色体/特异融合基因异常的检出率与准确率。联合常规细胞遗传学技术、多重巢式聚合酶链反应技术对120例急性白血病患者进行检测。结果表明:应用常规细胞遗传学检测出82例核型异常,占68.3%,而应用多重巢式聚合酶链反应技术检测出54例融合基因异常,占45%。联合这两种技术,120例急性白血病患者的遗传学异常检出率为:75%(90/120),其中有65例明确了具体染色体改变或特异性融合基因异常。30例患者经常规细胞遗传学检测出具有t(8;21)(q22;q22)或t(15;17)(q22;q12),多重巢式聚合酶链反应技术检测出39例患者具有AML1/ETO、PML/RARA或CBFB/MYH11融合基因异常。当存在染色体数目异常,或者不存在19种融合基因之一时多重巢式聚合酶链反应结果为阴性。提示常规细胞遗传学技术联合多重巢式聚合酶链反应技术可以有效地提高急性白血病患者染色体异常/特异性融合基因的检出率。 相似文献

Aggressive responding following benzodiazepine ingestion has been recorded in both experimental and client populations, however, the mechanism responsible for this outcome is unclear. The goal of this study was to identify an affective concomitant linked to diazepam‐induced aggression that might be responsible for this relationship. Thirty males (15 diazepam and 15 placebo) participated in the Taylor Aggression Paradigm while covertly being videotaped. The videotapes were analyzed using the Facial Action Coding System with the goal of identifying facial expression differences between the two groups. Relative to placebo participants, diazepam participants selected significantly higher shock settings for their opponents, consistent with past findings using this paradigm. Diazepam participants also engaged in significantly fewer appeasement expressions (associated with the self‐conscious emotions) during the task, although there were no group differences for other emotion expressions or for movements in general.

体验活动对冲动性购买行为的影响:情感反应视角 总被引:1,自引:0,他引:1
冲动性购买在商场和超市的零售中占有相当的比例,本研究以旅游者和旅游购物为实证研究对象,在323份调查问卷的基础上,采用方差分析和回归分析的方法探讨了体验活动对冲动性购买行为的影响及其情感反应机制。结果表明:在激发消费者冲动性购买行为方面,顾客参与的效果最好,其次是顾客学习,再次是顾客娱乐;顾客参与会导致更多的快乐的情感反应,而快乐的情感反应对冲动性购买意愿的影响最为显著;顾客学习会导致更多的支配的情感反应,而支配的情感反应对冲动性购买意愿的影响较为显著。 相似文献

The aim of the present experiments was to clarify sex differences in socio-developmental factors that affected defense behavior in rats. Sex differences in the defensive burying behavior of rats, and related social factors, were explored in three developmental stages: juvenile, puberty, and adult; 30, 50, and 80 days of age, respectively. The duration of burying, digging into bedding material, stretch-attend postures, and crouch/freezing were measured in a shock-prod test. For males, the duration of burying was longer in the juvenile and pubertal stages than in adulthood. For females, no age differences in the duration of burying were found. Males showed longer burying durations than females in both the juvenile and pubertal stages. For both sexes, the highest duration of digging was found in the juvenile stage, and females showed longer durations of digging than males. Both male and female rats isolated during the juvenile stage, from 26 to 40 days of age, showed smaller durations of burying behavior compared to pair-reared rats. This effect of juvenile isolation was maintained among both adult males and females even when they were returned to pair rearing after isolation. Isolation during adulthood, from 66 to 80 days of age, increased burying behavior in males, but decreased it in females. The durations of digging, stretch-attend postures, and crouch/freezing were not affected by isolation. The decrease in defensive burying and its increase resulting from isolation in adult male rats, suggest that the emergence of adult-like social relationships in males suppressed the duration of burying. Male and female rats isolated during the juvenile stage maintained lower levels of burying, suggesting that social experience as juveniles is important for the emergence of defensive burying behavior. 相似文献

有关数量化维度特征搜索的研究表明 ,目标搜索斜率 (反应时间对呈现项目数量函数的斜率 )是由目标与干扰子之间的差异决定的 ,然而以往研究中其差异的值取决于具体的实验条件。根据韦伯定律 ,笔者推测 ,目标搜索斜率应由目标与干扰子之间的相对差异 (C)决定 ,C为目标值 (T)与干扰子值 (D)的差值与该干扰子值的比值。当C值对应相等时 ,不同几何形状刺激的目标搜索斜率应无差异。为此笔者分别采用圆 (实验一 )和三角形 (实验二 )进行实验研究。实验结果支持了上述假设 ,并发现目标大于干扰子时的目标搜索斜率对C值的函数是单调递减函数 相似文献

Complex information, such as that required for motor skills, can be learned implicitly, without awareness. Much debate has centered on the appropriate methods for proving that implicit learning is not influenced by explicit awareness. A recent study by Destrebecqz and Cleeremans has provided compelling evidence for implicit sequence learning without awareness by using the ‘method of opposition’. 相似文献
