Using emotional cues in a discrimination learning task: Effects of trait emotional intelligence and affective state

Individuals may differ in their ability to learn the significance of emotional cues within a specific context. If so, trait emotional intelligence (EI) may be associated with faster cue learning. This study (N = 180) tested whether trait EI predicts faster learning of a critical cue for discriminating “terrorists” from “non-terrorists”, using virtual-reality heads as stimuli. The critical cue was either facial emotion (positive or negative), or a neutral feature (hat size). Cognitive ability and subjective state were also assessed. Participants were faster to learn with an emotive cue. Surprisingly, high trait EI was correlated with poorer performance, especially early in learning. Subjective distress was also associated with impaired learning to emotive cues.     

Genetic and environmental influences on executive functions and intelligence in middle childhood

Executive functions (EFs) and intelligence (IQ) are phenotypically correlated. In twin studies, latent variables for EFs and IQ display moderate to high heritability estimates; however, they show variable genetic correlations in twin studies spanning childhood to middle age. We analyzed data from over 11,000 children (9- to 10-year-olds, including 749 twin pairs) in the Adolescent Brain Cognitive Development (ABCD) Study to examine the phenotypic and genetic relations between EFs and IQ in childhood. We identified two EF factors—Common EF and Updating-Specific—which were both related to IQ (rs = 0.64–0.81). Common EF and IQ were heritable (53%–67%), and their genetic correlation (rG = 0.86) was not significantly different than 1. These results suggest that EFs and IQ are phenotypically but not genetically separable in middle childhood, meaning that this phenotypic separability may be influenced by environmental factors.     

Object-based and egocentric mental rotation performance in older adults: The importance of gender differences and motor ability

In this study, mental rotation performance was assessed in both an object-based task, human figures and letters as stimuli, and in an egocentric-based task, a human figure as a stimulus, in 60 older persons between 60 and 71 years old (30 women, 30 men). Additionally all participants completed three motor tests measuring balance and mobility. The results show that the reaction time was slower for letters than for both human figure tasks and the mental rotation speed was faster over all for egocentric mental rotation tasks. Gender differences were found in the accuracy measurement, favoring males, and were independent of stimulus type, kind of transformation, and angular disparity. Furthermore, a regression analysis showed that the accuracy rate for object-based transformations with body stimuli could be predicted by gender and balance ability. This study showed that the mental rotation performance in older adults depends on stimulus type, kind of transformation, and gender and that performance partially relates to motor ability.     

The role of analytic thinking in moral judgements and values

While individual differences in the willingness and ability to engage analytic processing have long informed research in reasoning and decision making, the implications of such differences have not yet had a strong influence in other domains of psychological research. We claim that analytic thinking is not limited to problems that have a normative basis and, as an extension of this, predict that individual differences in analytic thinking will be influential in determining beliefs and values. Along with assessments of cognitive ability and style, religious beliefs, and moral values, participants judged the wrongness of acts considered disgusting and conventionally immoral, but that do not violate care- or fairness-based moral principles. Differences in willingness to engage analytic thinking predicted reduced judgements of wrongness, independent of demographics, political ideology, religiosity, and moral values. Further, we show that those who were higher in cognitive ability were less likely to indicate that purity, patriotism, and respect for traditions and authority are important to their moral thinking. These findings are consistent with a “Reflectionist” view that assumes a role for analytic thought in determining substantive, deeply-held human beliefs and values.     

Derived Trail Making Test indices: demographics and cognitive background variables across the adult life span

We examined the contribution of demographics and cognitive background variables (processing speed, visuospatial skill, working memory, and interference control) on derived Trail Making Test (TMT) scores in a large sample of Greek healthy participants. We included 775 participants and administered the TMT (TMT-A and TMT-B) and the Wechsler Intelligence Adult Scale (WAIS). Direct (TMT-A & TMT-B time-to-completion) and derived [difference TMT-(B ? A) & ratio TMT-(B/A)] scores were calculated. Demographics (age, age², education, and gender) and WAIS Full Intelligence Quotient significantly predicted the direct TMT-A (R² = 0.426) and TMT-B (R² = 0.593) scores and to a lesser extent, the derived TMT-(B ? A) (R² = 0.343) and TMT-(B/A) (R² = 0.088) scores. In a subsample of 537 healthy participants who also completed the Stroop Neuropsychological Screening Test (SNST), demographics (age and education), WAIS Digit Symbol, Block Design, Arithmetic, and SNST accounted for 44.8% and 59.7% of the variance on TMT-A and TMT-B, and 32.5% and 9.6% of the variance on TMT-(B ? A) and TMT-(B/A), respectively. We found minimal influence of Block Design and Arithmetic on TMT-(B ? A) and an absence of significant influence of any cognitive variable on TMT-(B/A) score. Concluding, derived TMT scores are suggested as indices to detect impairment in cognitive flexibility across the adult life span, since they minimize the effect of demographics and other cognitive background variables.     

Weakness and compulsion: the essential difference

This paper aims to defend the common-sense view that we exempt compulsive agents from responsibility to the extent that they are unable to choose what they do and hence they cannot control their actions by their choices. This view has been challenged in a seminal paper by Gary Watson, who claimed that akratic agents lack control in the same sense but they are responsible nonetheless. In the first part of the paper, I critically examine the arguments Watson advances for this claim first in his original paper and then in some more recent works. I conclude that his account is based on the widely held assumption that both compulsive behavior and weakness of the will must be understood as a direct result of some inner motivational conflict. In the second part, I argue for an alternative understanding of the difference between weakness and compulsion. My claim is that compulsion is a cognitive rather than a motivational deficiency, since the compulsive, unlike the weak-willed, does not desire to perform the action which she actually performs. Furthermore, I argue that compulsive agents cannot control their actions by their choices because they have a distorted view of their own actional abilities. In the final part of the paper, I discuss a consequence of this account to the conditional analysis of free will as a condition of responsibility.     

Risques psychosociaux et capacité de travail des travailleurs âgés : validation du VOW/QFT

Work abilities are defined as a balance between worker own characteristics and the job requirements. The VOW/QFT has been developed in Belgium in order to understand older workers work ability by taking account of the risk factors related to the job strains, and in particular the psychosocial risk factors. The validation analysis of the VOW/QFT was carried out following the proposals of Churchill paradigm (Churchill, 1979; Roussel, 2005): exploratory analysis, confirmatory analysis and correlation analysis. The factorial structure of the questionnaire appeared stable; dimensions internal consistency is high. The regression analysis showed that work ability is explained to nearly 30% by the psychosocial risk factors, and mainly by the pleasure felt at work.     

直觉和分析在不同任务条件下的逃生决策效果

目的：探讨针对简单和复杂逃生任务时, 直觉和分析在不同判断依据条件下的逃生决策效果。方法：采用两个主实验和两个预备实验。实验一和实验二的被试人数分别为：85人和87人。两个主实验均采取2 (思维方式：直觉和分析) × 2 (判断依据：简单和复杂)组间实验设计。主要结果：(1)针对简单逃生任务, 直觉组和分析组在不同判断依据条件下的逃生决策效果差异不明显; (2)针对复杂逃生任务, 在简单判断依据条件下分析决策优于直觉决策; 在复杂判断依据条件下直觉决策优于分析决策。主要结论：直觉性和分析性逃生决策的效果主要与决策任务的复杂程度有关, 而与判断依据的复杂程度关系不大。
