Can orange colour facilitate the processing of happiness? An exploration study on happiness metaphor

Colour is a ubiquitous perceptual stimulus, and theoretical models of colour and psychological functioning posit that colour plays a key role in influencing the behaviour and mental function of a person. One investigation and two experiments investigated the colour metaphor representation of happiness concepts and the mapping mode of the colour metaphor of happiness concepts. A questionnaire was conducted to explore the relationship between colour preference and happiness. Study 2 shows that the identification of happiness words was facilitated more when words were viewed on an orange background than when viewed on a blue background. Study 3 further verifies the links of the connection between colour and happiness at the sentence level, and the orange-happiness facilitation effect was replicated. These results document a novel influence of colour on emotion recognition processes, where an orange background may facilitate the processing of the concept of happiness and provide support for conceptual metaphor theory and colour-in-context theory.     

SEM with Missing Data and Unknown Population Distributions Using Two-Stage ML: Theory and Its Application

This article provides the theory and application of the 2-stage maximum likelihood (ML) procedure for structural equation modeling (SEM) with missing data. The validity of this procedure does not require the assumption of a normally distributed population. When the population is normally distributed and all missing data are missing at random (MAR), the direct ML procedure is nearly optimal for SEM with missing data. When missing data mechanisms are unknown, including auxiliary variables in the analysis will make the missing data mechanism more likely to be MAR. It is much easier to include auxiliary variables in the 2-stage ML than in the direct ML. Based on most recent developments for missing data with an unknown population distribution, the article first provides the least technical material on why the normal distribution-based ML generates consistent parameter estimates when the missing data mechanism is MAR. The article also provides sufficient conditions for the 2-stage ML to be a valid statistical procedure in the general case. For the application of the 2-stage ML, an SAS IML program is given to perform the first-stage analysis and EQS codes are provided to perform the second-stage analysis. An example with open- and closed-book examination data is used to illustrate the application of the provided programs. One aim is for quantitative graduate students/applied psychometricians to understand the technical details for missing data analysis. Another aim is for applied researchers to use the method properly.     

Does instrumental motivation help students with low intrinsic motivation? Comparison between Western and Confucian students

The research examines possible differences in the mutual reinforcement (i.e. multiplicative) effect between intrinsic and instrumental motivation on academic performance across different cultures. Eight representative countries and economies from two large-scale databases—the Trends in International Mathematics and Science Study (TIMSS) 2011 and the Programme for International Student Assessment (PISA) 2012—were used, respectively. Results showed that among the Confucian economies, instrumental motivation was more helpful in improving the mathematics performance of students with low intrinsic motivation than for those with high intrinsic motivation. This was shown by the multiplicative effect between intrinsic and instrumental motivation. Despite the difference, students in both Confucian and Western cultures with high intrinsic motivation had better mathematics performance than students with low intrinsic motivation.     

BDNF: a key regulator for protein synthesis-dependent LTP and long-term memory?

It is generally believed that late-phase long-term potentiation (L-LTP) and long-term memory (LTM) require new protein synthesis. Although the full complement of proteins mediating the long-lasting changes in synaptic efficacy have yet to be identified, several lines of evidence point to a crucial role for activity-induced brain-derived neurotrophic factor (BDNF) expression in generating sustained structural and functional changes at hippocampal synapses thought to underlie some forms of LTM. In particular, BDNF is sufficient to induce the transformation of early to late-phase LTP in the presence of protein synthesis inhibitors, and inhibition of BDNF signaling impairs LTM. Despite solid evidence for a critical role of BDNF in L-LTP and LTM, many issues are not resolved. Given that BDNF needs to be processed in Golgi outposts localized at the branch point of one or few dendrites, a conceptually challenging problem is how locally synthesized BDNF in dendrites could ensure synapse-specific modulation of L-LTP. An interesting alternative is that BDNF-TrkB signaling is involved in synaptic tagging, a prominent hypothesis that explains how soma-derived protein could selectively modulate the tetanized (tagged) synapse. Finally, specific roles of BDNF in the acquisition, retention or extinction of LTM remain to be established.     

品牌信任的前因后果驱动机制研究

本研究通过大样本问卷调查,采用结构方程建模的方法探讨品牌信任的前因后果驱动机制.结果表明:品牌的直接经验和间接经验通过品牌态度和品牌信任的中介作用对品牌绩效发生影响,其中品牌直接经验比品牌间接经验对品牌态度的影响更大.这说明只有消费者对品牌产生了亲身体验以后,才会实质性地改变对品牌的态度和信任.品牌信任是导致品牌绩效的直接因素.
