The impact of eye movements on a verbal creativity task

Bilateral eye movements (EMs) have been shown to induce cognitive enhancements for episodic memory, attention, and divergent thinking. Increased interhemispheric interaction has been suggested as a possible mechanism behind the EM effect, but other theories, including an increase in attentional control following EMs have also been proposed. The present research explored whether the bilateral EM effect could be extended to a creativity task that draws heavily on convergent thinking. Participants were randomly assigned to one of four EM conditions (bilateral, centre control, right-centre, or left-centre) and were presented with compound remote associate problems. After 7 s, participants were asked to make a solution/non-solution judgement to a target word presented in the left or right visual field. Bilateral and right-centre EM conditions exhibited enhanced performance on the task, with the bilateral condition demonstrating the best performance for solution targets and the right-centre condition presenting the best performance for non-solution targets. The implications of these findings are discussed in light of the neural components of creativity and theories surrounding the effects of EMs on cognition.     

Factor structure and measurement invariance of a short measure of the Big Five personality traits

The main purpose of this study is to assess the factor structure and the measurement invariance of the Mini-International Personality Item Pool (Mini-IPIP; Donnellan, Oswald, Baird, & Lucas, 2006). The Mini-IPIP is a brief instrument evaluating personality traits according to the Big Five models. Two samples were collected comprising nearly 800 participants. Confirmatory factor analyzes revealed a five-factor solution consistent with the Big Five model. Measurement invariance analyses showed that the Mini-IPIP was reasonably invariant across samples, genders and age groups. Overall, results pointed to a satisfactory factorial structure and an adequate invariance of the measure.     

Measurement invariance of the Mental Health Continuum-Short Form (MHC-SF) across three cultural groups

This study investigated the factorial structure and invariance of the Mental Health Continuum-Short Form (MHC-SF) across cultural groups from three nations, namely, the Netherlands, South Africa, and Iran (N = 1120). The three-dimensional structure of mental well-being was supported in all the groups. The results of measurement invariance testing confirmed the full metric and partial scalar invariance of the MHC-SF. The study also compared the latent means for the aspects of mental well-being in the three cultural groups, and found significant differences. The significance and implications of the results are discussed.     

Factor structure and initial validation of a brief measure of perceived emotional and physical distress tolerance in post-9/11 US Veterans

Distress tolerance (i.e., perceived or actual capacity to tolerate aversive internal states) has received considerable research attention as a transdiagnostic risk-factor underlying the development and maintenance of psychopathology. Lower levels of emotional distress tolerance have been linked to psychopathology (e.g. Posttraumatic Stress Disorder) within Military populations; however, the association of physical distress tolerance to psychopathology in this population has been under-researched. This research gap may be due in part to a paucity of comprehensive, temporally stable and brief measures of distress tolerance that have been validated within Military populations, which may hinder further examination and refinement of the construct. Addressing this problem, the current study evaluates the psychometric properties of a novel and brief measure of emotional and physical distress tolerance in a sample of United States post-9/11 Veterans. Participants were 307 Veterans (M_age = 38.9, 67.7% male) who completed the 10-item Distress Tolerance Inventory at baseline and annual follow-up. Exploratory structural equation modeling was used to examine the optimal latent factor structure and longitudinal invariance of the DTI measurement model, along with correlational analyses to examine the convergent properties of the DTI subscales. The DTI reflected a longitudinally invariant two-factor structure (emotional and physical distress tolerance), with excellent internal consistency and preliminary evidence of convergent validity. Thus, the DTI represents a brief, reliable and temporally stable measure of physical and emotional distress tolerance.     

Factorial invariance of the Rahim emotional quotient index

This study investigated the degree of factorial invariance of the 30-item Rahim Emotional Quotient Index (REQI) (Afzalur Rahim et al., 2002 Afzalur Rahim, M., Psenicka, C., Polychroniou, P., Zhao, J.-H., Yu, C.-S., Anita Chan, K., van Wyk, R. (2002). A model of emotional intelligence and conflict management strategies: A study in seven countries. The International Journal of Organizational Analysis, 10(4), 302–326. http://dx.doi.org/10.1108/eb028955[Crossref] , [Google Scholar]) across gender and language, using multiple group confirmatory factor analysis. Respondents were 341 full-time employed applicants to programmes in a South African Business School (females = 39.6%, African language group = 60.1%; non-African/Western language group = 39.9). With regard to age, the majority of the sample (25.5%) fell into the category 31–35 years. The Satorra-Bentler scaled chi-square difference tests showed no statistically significant differences between different gender and language groups, with regard to factor structure, factor loadings, variances and covariance. The findings support the original five-factor structure of the REQI for the two language groups, as well as the two gender groups.     

Putting the bits together: an information theoretical perspective on morphological processing

In this study we introduce an information-theoretical formulation of the emergence of type- and token-based effects in morphological processing. We describe a probabilistic measure of the informational complexity of a word, its information residual, which encompasses the combined influences of the amount of information contained by the target word and the amount of information carried by its nested morphological paradigms. By means of re-analyses of previously published data on Dutch words we show that the information residual outperforms the combination of traditional token- and type-based counts in predicting response latencies in visual lexical decision, and at the same time provides a parsimonious account of inflectional, derivational, and compounding processes.     

Newborns' recognition of changing and unchanging aspects of schematic faces

The present study investigated newborns' ability to discriminate, recognize, and learn visual information embedded in the schematic face-like patterns preferred at birth. Four experiments were carried out using the visual-paired comparison paradigm. Results indicated that newborns discriminated face-like stimuli relying on their internal features (Experiments 1 and 4) and recognized a perceptual invariance between face-like configurations in conditions of low (Experiment 2) and high-perceptual variability (Experiment 3) of their inner elements. Altogether, data show that the presence of the preferred structure that schematically defines a face, displaying a triplet of elements in the correct locations for eyes and mouth, does not constitute a limit that constrains newborns' face learning processes.     

MATURE CONTEMPLATION

Abstract. This chapter extends biogenetic structural theory to a consideration of the biopsychological principles underlying higher phases of consciousness, particularly those attained by the systematic exploration of consciousness called contemplation. The concepts of psychic energy, flow, centeredness, energy circulation, and dreambody are explored as presented in various mystical traditions, and a model of the underlying neurophysiology is presented in terms of ergotropic-trophotropic tuning. The psychophysiology of various forms of meditation together with emergent peak experiences is examined and integrated into the ergotropic-trophotropic tuning model. Structural invariance of ergotropic-trophotropic tuning as well as invariant aspects of contemplation across different cultures and associated with different symbol systems is considered. Finally the nature and implications of Void Consciousness, God Consciousness, or Abssolute Unitary Being are examined.     

镜像等效或守恒及其打破：从行为到认知神经机制的研究证据

镜像等效或守恒是动物与人类个体对两侧对称自然物体的一种进化自适应加工。但是, 这种知觉特性会妨碍包含镜像字符的文字阅读学习。阅读者有必要学会利用镜像泛化抑制的“去学习”机制, 打破镜像等效或守恒, 以获得识别镜像字符的能力。这一过程中, 左侧梭状回皮层通过与早期视觉皮层、顶叶皮层和口语脑网络的交互作用, 逐渐发展出一个可以识别镜像字符的视觉词形区(visual word form area, VWFA)。今后的研究需要关注两半球及其连合纤维在镜像等效或守恒加工中的作用、镜像泛化与抑制的详尽加工机制及其对镜像书写的影响、正常汉语儿童的汉字镜像泛化加工等问题。
