乐商:一个比智商和情商更能决定命运的因素

乐商(或乐观智力)是指人乐观的能力,它既包括一个人乐观水平的高低,也包括个体从所经历的消极事件中获取积极成分的能力,以及影响或感染他人的能力.“杜乡微笑”是高乐商的一种主要外在表现形式.心理学过去的有关研究证实,高乐商不仅有利于个体的社会性发展、获得稳定的幸福婚姻、提高人的生理健康水平、提高学业成绩和减少坏事情的发生,而且高乐商还有利于促使个体寻求社会支持和社会交往.这些研究结果表明,乐商可能是一个比智商和情商更能决定人未来发展命运的因素.     

Measuring Schwartz's values in childhood: Multidimensional scaling across instruments and cultures

The Picture-Based Value Survey for Children (PBVS-C; Döring et al., 2010) assesses children's values through self-report and thereby depicts Schwartz's theory of universal human values at an early age. Despite evidence on the PBVS-C's structural validity, there remains an open question: Does the PBVS-C measure the same values as does Schwartz's Portrait Values Questionnaire (PVQ; Schwartz et al., 2001), an established assessment instrument for adult and adolescent respondents? To answer this question about the PBVS-C's validity, Polish (N = 167) and German (N = 119) children's values were measured with both instruments. The multitrait–multimethod correlation matrix (Campbell & Fiske, 1959) of value items from both instruments was analysed with multidimensional scaling (MDS), as proposed by Borg and Groenen (1997). Our structural expectations for the MDS output about the distinctiveness (1) of Schwartz's higher order value types (i.e., traits) and (2) of the two assessment methods (PBVS-C and PVQ) were confirmed in both samples.

Selflessness as a universal neuropsychological foundation of spiritual transcendence: validation with Christian,Hindu, and Muslim traditions

Research with US and European Christians has shown that increased spiritual transcendence is related to decreased right hemisphere/right parietal lobe (RH/RPL) functioning, which has been inferred as relating to increased “selflessness”. To determine if RH/RPL selflessness is a universal neuropsychological foundation for spiritual transcendence across cultures and religions, this study evaluated 109 individuals with traumatic brain injury from the US and India, including Christians, Hindus, and Muslims. Participants completed measures of spiritual transcendence and spatial perception as an index of the functional integrity of the RH/RPL. Spearman correlations indicated that decreased RH/RPL functioning is significantly associated with increased spiritual transcendence for the entire sample, but not for different cultures or religions, likely due to decreased statistical power. The results suggest that decreased RH/RPL-related selflessness is a universal neuropsychological foundation for spiritual transcendence across cultures and faith traditions, which is interpreted individually based on cultural and religious background (e.g., closeness to God, Allah, and Brahman).     

Visual knowledge discovery and machine learning for investment strategy

Knowledge discovery is an important aspect of human cognition. The advantage of the visual approach is in opportunity to substitute some complex cognitive tasks by easier perceptual tasks. However for cognitive tasks such as financial investment decision making this opportunity faces the challenge that financial data are abstract multidimensional and multivariate, i.e., outside of traditional visual perception in 2D or 3D world. This paper presents an approach to find an investment strategy based on pattern discovery in multidimensional space of specifically prepared time series. Visualization based on the lossless Collocated Paired Coordinates (CPC) plays an important role in this approach for building the criteria in the multidimensional space for finding an efficient investment strategy. Criteria generated with the CPC approach allow reducing/compressing space using simple directed graphs with beginnings and the ends located in different time points. The dedicated subspaces constructed for time series include characteristics such as Bollinger Band, difference between moving averages, changes in volume etc. Extensive simulation studies have been performed in learning/testing context. Effective relations were found for one-hour EURUSD pair for recent and historical data. Also the method has been explored for one-day EURUSD time series n 2D and 3D visualization spaces. The main positive result is finding the effective split of a normalized 3D space on 4 × 4 × 4 cubes in the visualization space that leads to a profitable investment decision (long, short position or nothing). The strategy is ready for implementation in algotrading mode.     

Evaluating fit of the Prospective and Retrospective Memory Questionnaire (PRMQ) in a Nigerian adult population

This study aimed to evaluate the latent structure of the Prospective and Retrospective Memory Questionnaire (PRMQ) and to estimate the reliability and validity of scores from the measure in a Nigerian adult population (N = 758; age range = 18 - 63 years; females = 52.24%). Respondents also completed the Cognitive Failures Questionnaire (CFQ). The data were analysed utilising confirmatory factor analysis (CFA). The results suggest the PRMQ to have a tripartite structure characterised by the following features: general memory, plus eight prospective and eight retrospective memory items. Scores from the PRMQ had evidence of convergent validity with the CFQ. The reliability of scores from the PRMQ was of acceptable magnitude for the research purposes investigated in the study.     

Validation of Dating Violence Questionnarie-R (DVQ-R)

Background/Objective

Despite the growing interest in the study of dating violence, relatively few psychometrically sound instruments are available to researchers. To provide an instrument to researchers and professionals to assess victimization in dating relationships, with adequate psychometric properties. Method: Participants were 6,138 adolescents drawn from the general population, 25% of which were university students. Participants responded to the original Dating Violence Questionnaire (DVQ). Results: Confirmatory analyses results provided evidence of a clear factorial structure that was invariant through sex groups. The DVQ-R measures with 20 items five dimensions of abuse in affective interpersonal relationships of adolescents and youth: Detachment, Humiliation, Coercion, Physical and Sexual violence. Internal consistency indexes were adequate for both each one of the five dimensions as well as for the general scale. Conclusions: The DVQ-R is an useful assessment to be applied in adolescents and youth. Implications for research and intervention are discussed in light of the results obtained.     

Interoception and gender: What aspects should we pay attention to?

Interoception is involved in both somatic and mental disorders with different prevalence between genders; however, gender differences are often neglected. To examine the potential gender differences in interoceptive awareness, we recruited 376 healthy subjects (51% males, aged 17–30 years), to fill in the Multidimensional Assessment of Interoceptive Awareness (MAIA). Of that sample, in a subgroup of 40 subjects (50% males), interoceptive accuracy was assessed by heartbeat counting task (HCT).The results on interroceptive awareness suggest that females tend to notice bodily sensations more often, better understand relations between bodily sensations and emotional states, worry or experience more emotional distress with sensations of pain or discomfort and see body as less safe. The results of interoceptive accuracy further suggest that females are less efficient in consciously detecting heartbeats. Therefore, gender should be considered when interoceptive evaluation is performed in disorders associated to bodily sensations and to the emotional/mood states.     

Relationship between language switching experience and executive functions in bilinguals: an Internet-based study*

We examined the relationship between self-reported everyday language switching experience and the performance of early bilinguals in tasks measuring different executive functions. Our participants were Finnish–Swedish early bilinguals, aged 16–41 years (N?=?66, Experiment 1) and 18–69 years (N?=?111, Experiment 2). An earlier study using a sample from a similar population discovered a negative relationship between self-reported language switching and a mixing cost in error rates in a number–letter task. This finding was not replicated. Instead, we found that a higher rate of reported contextual language switching predicted larger switching cost reaction times in the number–letter task, and that a higher rate of reported unintended language switches predicted larger error rates in a spatial n-back task. We conclude that these results likely reflect individual differences in executive skills, and do not provide evidence for the hypothesis that language switching trains executive functions.
