Measuring Creativity with Planned Missing Data

This paper introduces a method for the assessment of creativity that relies on creativity tasks, a subjective evaluation procedure, and a planned missing data design that offers a drastic reduction in the overall implementation costs (administration time and scoring procedure). This method was tested on a sample of 149 people, using three creativity tasks as a basis. Participants were instructed to produce several ideas in each task and then to select what they considered to be their best two ideas (i.e., “Top 2” procedure; Silvia, Winterstein, Willse, Barona, et al., Psychology of Aesthetics, Creativity, and the Arts, 2 , 2008 and 68). These ideas were then evaluated by a panel of peers and experts. Creativity ratings were analyzed with structural equations; measurement models were estimated for each task and correlations between factor-scores across the three tasks were investigated. Further insights regarding validity are provided through systematic investigation of the relationship between fluency scores, creativity ratings, intelligence tasks, self-reported idea generation abilities, and creative activities and achievements. Overall, the results support the viability of this new approach, providing evidence of convergent and discriminant validity. They are discussed in relation to past research and avenues for further extension are proposed.     

Predicting psychological service providers' empowerment in the light of the COVID‐19 pandemic outbreak: A structural equation modelling analysis

This study aimed to investigate the predictors of psychological service providers' empowerment in the light of the COVID‐19 pandemic outbreak. The researcher prepared a psychological service providers' empowerment scale that consisted of 28 items, and this scale was applied in a random sample consisting of 975 psychological service providers. The results showed that the empowerment scale has acceptable validity and reliability. The results of the exploratory factor analysis indicated that the 28 scale items saturate on seven factors, which accounted for 64.42% of the total variance of the scale: the first factor named expect psychological services effectiveness accounted for 27.86%, the second factor named self‐stimulation accounted for 9.71%, the third factor named responsibilities and duties accounted for 7.12%, the fourth factor named psychological services work environment accounted for 6.51%, the fifth factor named psychological service providers’ decision‐making accounted for 5.37%, the sixth factor named creative psychological service provider behaviour accounted for 4.45%, and the seventh factor named psychological services confidence accounted for 3.82% of the total variance of a psychological service providers' empowerment. In order to study the ability to predict the empowerment among psychological service providers, the researcher developed a structural model for psychological service providers' empowerment and then used the structural equation model analysis. The results showed that the proposed structural model of a psychological service providers' empowerment has goodness‐of‐fit, and these results emphasised the ability to predict psychological service providers' empowerment by seven tested factors.

Assessing changes in brain electrical activity and functional connectivity while overtaking a vehicle

ABSTRACT

Driving is a daily requirement and an indispensable activity for many people. However, still little is known about how driving is supported by the brain. We used electroencephalography to study the changes in brain activity and its functional connectivity in a simulated driving task. We focused on overtaking and studied this activity in three phases: before overtake, during overtake, and after overtake. Our results showed that mu power in motor and sensorimotor areas decreased during overtake and again increased after overtake. On the other hand, beta oscillations in frontal areas were at their highest level in the “before overtake” phase. It can be interpreted that the “before overtake” was the most attention-demanding phase. In addition, we found that the connectivity between right and left prefrontal regions and right and left occipital regions in alpha (and mu) band power was significantly stronger in the “during overtake” compared to the other two conditions.     

Neural basis responsible for self-control association with procrastination: Right MFC and bilateral OFC functional connectivity with left dlPFC

Converging theory and evidence highlights procrastination as a form of self-control failure. However, the underlying neural correlates of how self-control is associated with procrastination remains unclear. As such we investigated the neural basis for self-control association with procrastination using voxel-based morphometry (VBM) and resting-state functional connectivity (FC) approaches. The VBM results showed a positive correlation between self-control and the gray matter volume of left dorsolateral prefrontal cortex (dlPFC). Then the FC of left dlPFC to lateral orbital frontal cortex (lOFC) and right dorsal medial frontal cortex (dMFC) were all negatively correlated to procrastination and showed a mediating effect. This indicates that brain functional communication involves in emotion regulation and valuation processing may account for the association between self-control and procrastination.     

工作连通行为的双刃剑效应：多重任务倾向的调节作用

随着移动通信工具飞速发展,“全天候保持工作连通”的新时代已到来。在此背景下,工作连通行为对员工工作与生活的影响受到广泛关注。基于工作要求-资源模型,通过258份三时点的领导-员工配对数据探究工作连通行为的双刃剑效应。路径分析结果表明,工作连通行为一方面会通过工作目标进展进而影响员工工作绩效(积极路径),另一方面又会通过工作负荷进而导致工作-家庭冲突(消极路径)。多重任务趋向在上述两条路径过程中发挥调节作用,对于高多重任务趋向的员工, 积极路径的效果被强化,而消极路径的效果被削弱。     

The role of the cingulate cortex in the generation of motor tics and the experience of the premonitory urge-to-tic in Tourette syndrome

Tourette syndrome (TS) is a neurological disorder of childhood onset that is characterized by the occurrence of motor and vocal tics. TS is associated with cortical-striatal-thalamic-cortical circuit [CSTC] dysfunction and hyper-excitability of cortical limbic and motor regions that are thought to lead to the occurrence of tics. Individuals with TS often report that their tics are preceded by ‘premonitory sensory/urge phenomena’ (PU) that are described as uncomfortable bodily sensations that precede the execution of a tic and are experienced as a strong urge for motor discharge. While the precise role played by PU in the occurrence of tics is largely unknown, they are nonetheless of considerable theoretical and clinical importance as they form a core component of many behavioural therapies used in the treatment of tic disorders. Recent evidence indicates that the cingulate cortex may play an important role in the generation of PU in TS, and in ‘urges-for-action’ more generally. In the current study, we utilized voxel-based morphometry (VBM) techniques, together with ‘seed-to-voxel’ structural covariance network (SCN) mapping, to investigate the putative role played by the cingulate cortex in the generation of motor tics and the experience of PU in a relatively large group of young people with TS. Whole-brain VBM analysis revealed that TS was associated with clusters of significantly reduced grey matter volumes bilaterally within: the orbito-frontal cortex; the cerebellum; and the anterior and mid-cingulate cortex. Similarly, analysis of SCNs associated with bilateral mid- and anterior cingulate ‘seed’ regions demonstrated that TS is associated with increased structural covariance primarily with the bilateral motor cerebellum; the inferior frontal cortex; and the posterior cingulate cortex.
