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.     

High working memory load leads to more Ebbinghaus illusion

The evidence that distractor processing increases with greater load on working memory has come mainly from Stroop-type interference tasks, making it difficult to establish whether cognitive load affects distractor processing at the perceptual level or during response selection. We measured the Ebbinghaus illusion under varying levels of working memory load to test whether cognitive control is also relevant for preventing processing of distractors that do not produce any response conflict, and instead affect target processing at the perceptual level. The Ebbinghaus illusion was greater under high working memory load, suggesting that availability of cognitive control functions is critical to reduce distractor processing even for distractors that are not associated with a response. We conclude that the effect of loading working memory during selective attention leads to greater distractor perception.     

On the Likelihood Ratio Tests in Bivariate ACDE Models

The ACE and ADE models have been heavily exploited in twin studies to identify the genetic and environmental components in phenotypes. However, the validity of the likelihood ratio test (LRT) of the existence of a variance component, a key step in the use of such models, has been doubted because the true values of the parameters lie on the boundary of the parameter space of the alternative model for such tests, violating a regularity condition required for a LRT (e.g., Carey in Behav. Genet. 35:653–665, 2005; Visscher in Twin Res. Hum. Genet. 9:490–495, 2006). Dominicus, Skrondal, Gjessing, Pedersen, and Palmgren (Behav. Genet. 36:331–340, 2006) solve the problem of testing univariate components in ACDE models. Our current work as presented in this paper resolves the issue of LRTs in bivariate ACDE models by exploiting the theoretical frameworks of inequality constrained LRTs based on cone approximations. Our derivation shows that the asymptotic sampling distribution of the test statistic for testing a single bivariate component in an ACE or ADE model is a mixture of χ ² distributions of degrees of freedom (dfs) ranging from 0 to 3, and that for testing both the A and C (or D) components is one of dfs ranging from 0 to 6. These correct distributions are stochastically smaller than the χ ² distributions in traditional LRTs and therefore LRTs based on these distributions are more powerful than those used naively. Formulas for calculating the weights are derived and the sampling distributions are confirmed by simulation studies. Several invariance properties for normal data (at most) missing by person are also proved. Potential generalizations of this work are also discussed.     

Task complexity matters: The influence of trait mindfulness on task and safety performance of nuclear power plant operators

People with high level of trait mindfulness are more likely to maintain an open and present-focused awareness and attention. Whereas a positive link between trait mindfulness and well-being has been established, its influence on real-world performance has not been fully addressed. In Study 1, we validated the Freiburg Mindfulness Inventory (FMI) in a Chinese sample (N = 294) and found that a two-dimensional solution (a presence factor and an acceptance factor) best fit the data. In Study 2, using this validated scale, we directly investigated the influence of trait mindfulness on task and safety performance. In a sample of 136 Chinese nuclear power plant operators, it was found that trait mindfulness interacted with task complexity to influence performance. For high-complexity-task holders (the control room operators), the presence factor was positively related to their task and safety performance; for the low-complexity-task holders (the field operators), the presence factor had no influence on safety performance but a negative influence on task performance. The acceptance factor did not have any meaningful influences. These results suggest that the benefit of being mindful outweighs its cost for complex but not simple tasks. Implications are discussed.

序列学习是否是内隐学习？

序列学习是继人工语法之后内隐学习的另一研究范式。以往观点认为,在练习后,被试对规则刺激和随机刺激在反应时上出现差异,就表明被试是内隐学习,这种差异量就是内隐学习量。但现在很多学者对序列学习是否内隐这一问题提出了疑问;运用新方法（过程分离法,简称PDP）的研究发现,序列学习是否内隐同反应-刺激间隔（RSI）有关,当RSI = 0时,序列学习才是内隐的;根据RSI提出了神经网络模型。

舞动治疗对高校辅导员职业倦怠的干预研究

旨在探讨舞动治疗对于辅导员职业倦怠干预的效果,为辅导员缓解职业倦怠提供方法和依据。采用简单随机抽样方法,从三所高校中抽取60名辅导员进行研究,分为两组,通过舞动治疗与普通系列讲座两种方式,并前后对照探讨舞动治疗对高校辅导员职业倦怠的影响。研究采用前后测对照组实验组实验法,使用问卷对60名辅导员进行调查研究。问卷共包括两部分,分别为一般自我效能感量表（GSES）和Maslach职业倦怠量表（MBI-GS）。结果显示舞动治疗后职业倦怠的情绪耗竭和玩世不恭维度得分显著下降,成就感得分显著上升,自我效能感显著提升;系列讲座后职业倦怠的玩世不恭和成就感得分没有变化,情绪耗竭得分明显增加,自我效能感没有改善。由此可以看出舞动治疗可以改善高校辅导员的职业倦怠状况。
