It has been reported that the ability to solve syllogisms is highly g-loaded. In the present study, using a self-administered shortened version of a syllogism-solving test, the BAROCO Short, we examined whether robust findings generated by previous research regarding IQ scores were also applicable to BAROCO Short scores. Five syllogism-solving problems were included in a questionnaire as part of a postal survey conducted by the Keio Twin Research Center. Data were collected from 487 pairs of twins (1021 individuals) who were Japanese junior high or high school students (ages 13–18) and from 536 mothers and 431 fathers. Four findings related to IQ were replicated: 1) The mean level increased gradually during adolescence, stayed unchanged from the 30s to the early 50s, and subsequently declined after the late 50s. 2) The scores for both children and parents were predicted by the socioeconomic status of the family. 3) The genetic effect increased, although the shared environmental effect decreased during progression from adolescence to adulthood. 4) Children's scores were genetically correlated with school achievement. These findings further substantiate the close association between syllogistic reasoning ability and g. 相似文献

Although laughter plays an essential part in emotional vocal communication, little is known about the acoustical correlates that encode different emotional dimensions. In this study we examined the acoustical structure of laughter sounds differing along four emotional dimensions: arousal, dominance, sender's valence, and receiver-directed valence. Correlation of 43 acoustic parameters with individual emotional dimensions revealed that each emotional dimension was associated with a number of vocal cues. Common patterns of cues were found with emotional expression in speech, supporting the hypothesis of a common underlying mechanism for the vocal expression of emotions. 相似文献

Are Decisions Made by Group Representatives More Risk Averse? The Effect of Sense of Responsibility 下载免费PDF全文
We tested the hypothesis that a sense of responsibility drives group representatives' decisions to be more risk averse compared with decisions made by individuals. The hypothesis was supported when the monetary considerations (i.e., payoff inequality and the magnitude effect) were controlled for in the potential gain domain as well as in the potential loss domain. Evidence showed that this is because the group representatives were concerned about how they would view themselves (e.g., guilt and self‐blame) and also how they would be viewed by others (i.e., to avoid being blamed and looked down upon by others). This study provided new insights into understanding group representatives' decision making under risk. Copyright © 2017 John Wiley & Sons, Ltd. 相似文献

This study evaluates the effectiveness of dialectical behaviour therapy (DBT) for borderline personality disorder (BPD) in an unselected, comorbid population seeking 3-month inpatient treatment. We studied 50 consecutively admitted individuals (44 women, six men) with BPD as defined by DSM-IV at three time points (at admission, at discharge, and at the 15-month follow-up). For the clinical diagnoses, we used the Structured Clinical Interview for DSM-IV (SCID) and compared the frequencies of comorbid axis I and axis II disorders at admission and at the 15-month follow-up. Overall, participants showed a high degree of comorbidity. Psychopathology was significantly reduced at post-treatment and at follow-up. Effect sizes for outcome measures were within the range of those of previous studies. Our findings support the notion that the results of the DBT efficacy research can be generalized to an inpatient setting and to patients with BPD disorder with high comorbidity. 相似文献

幼儿元认知"乐观主义现象"研究述评 总被引:3,自引:0,他引:3
儿童元认知发展是当代发展心理学研究的热点领域之一,其中儿童对自身能力的认识与评估又是研究者很感兴趣的课题。大量研究表明,与年长儿童和成人相比,年幼儿童特别是学龄前儿童往往对自己的能力和在各种任务中的成绩作出不切实际的高估,这种高估具有跨领域的一致性,并且具有内在固执性,即通常不受过去失败经验的影响。这就是所谓幼儿元认知“乐观主义现象”。本文对这一领域的相关研究进行整体回顾与分析,并在此基础上尝试对这一现象产生的原因及影响因素作出解释和说明。 相似文献

People generally consider money a necessary evil because it invokes dual effects. On one hand, it increases people's productivity and performance, but it also decreases people's sensitivity to others. I conducted three experimental studies with an attempt to reduce the negative effects of money. Results indicated that when money was framed as a social incentive, its negative effect was attenuated and people exerted more helping behavior in both hypothetical and real‐life scenarios. However, when a social incentive was framed in monetary terms, the negative effect of money prevailed in hypothetical but not in real‐life scenarios. Results suggested that money itself is not the root of evil or good, but rather its effects are influenced by our perceptions of its role. 相似文献
