Investigation of Psychometric Properties of the Georgian Version of Posttraumatic Growth Inventory

This paper reports the analysis of psychometric properties of the Georgian version of the Posttraumatic Growth Inventory (PTGI-Geo). In particular, factor structure, internal consistency of the subscales, gender differences, and relation between traumatic event category and posttraumatic growth (PTG) are examined. The study had 641 participants in two studies (study 1, n = 300; study 2, n = 341 participants). The study revealed that PTGI-Geo consists of four factors, instead of the original five factors; namely, the first three factors (New Possibilities, Relation to Others, and Personal Strength) remained unchanged, while the fourth (Spiritual Change) and the fifth (Appreciation of Life) factors merged and formed a new fourth factor. All four new factors have similar internal consistency as the original inventory. There were also some between-person differences for gender consistent with other research.     

孤独症谱系障碍者的视觉-空间工作记忆缺陷及脑机制

孤独症谱系障碍(ASD)个体存在视觉-空间工作记忆加工缺陷,主要表现在4个方面,即随认知负荷增大而缺陷加重、工作记忆容量不足、工作记忆加工过程中的注意功能失调和对刺激进行整体组织的能力缺乏。神经机制研究显示,ASD个体存在明显的额-顶工作记忆网络激活异常,以及相关脑区的脑结构、白质连接异常。另外,作为基础性的认知加工过程,ASD个体的视觉-空间工作记忆各加工环节与言语工作记忆、执行功能、社会认知等因素均存在交互影响。纵观目前研究成果,未来研究可从研究手段、机制探究和干预训练三方面入手,着眼于研究方法的生态化和多元化,揭示客体和空间工作记忆的机制分离,并着力开发更具针对性的干预训练模式。     

Occupational differences in work engagement: A longitudinal study among eight occupational groups in Norway

The aim of the present study was to explore occupational differences in the experience of engagement both with regard to differences in the level of work engagement as well as in the predicting value of different antecedent variables. Multigroup latent mean analysis was performed on eight different occupational groups in Norway (lawyers, physicians, nurses, teachers, church ministers, bus drivers, and people working in advertising and information technology; N = 3,475). Tests for factorial invariance supported the use of the Oldenburg Burnout Inventory scale across occupational groups and that the latent means were comparable across the groups. Results indicated significant occupational differences in the experience of vigor and dedication. The lawyers reported the most vigor and the church ministers the most dedication. Least vigor was reported among the teachers and the advertising group reported to be least dedicated. Cross‐lagged multigroup structural equation modeling (SEM) analysis suggested there are different processes behind the development of engagement across occupations. Visualization of how some occupations cluster or differ from each other is important as it might engender theory building and further hypotheses testing.     

Iconicity and the Emergence of Combinatorial Structure in Language

In language, recombination of a discrete set of meaningless building blocks forms an unlimited set of possible utterances. How such combinatorial structure emerged in the evolution of human language is increasingly being studied. It has been shown that it can emerge when languages culturally evolve and adapt to human cognitive biases. How the emergence of combinatorial structure interacts with the existence of holistic iconic form‐meaning mappings in a language is still unknown. The experiment presented in this paper studies the role of iconicity and human cognitive learning biases in the emergence of combinatorial structure in artificial whistled languages. Participants learned and reproduced whistled words for novel objects with the use of a slide whistle. Their reproductions were used as input for the next participant, to create transmission chains and simulate cultural transmission. Two conditions were studied: one in which the persistence of iconic form‐meaning mappings was possible and one in which this was experimentally made impossible. In both conditions, cultural transmission caused the whistled languages to become more learnable and more structured, but this process was slightly delayed in the first condition. Our findings help to gain insight into when and how words may lose their iconic origins when they become part of an organized linguistic system.     

5f-electron localization in the actinide metals: thorides,actinides and the Mott transition

For the light actinides Ac–Cm, the numbers of localized and itinerant 5f-electrons are determined by comparing various estimates of the f-electron counts. At least one itinerant f-electron is found for each element, Pa–Cm. These results resolve certain disagreements among electron counts determined by different methods and are consistent with the Mott transition model and with the picture of the 5f-electrons’ dual nature.     

Identity status and perceived parenting style in adolescents living in central South Africa

This study investigated the relationship between black South African adolescents’ identity statuses and their perceived parenting styles. Participants (n = 188; 66% = females) were from central South Africa. They completed the Objective Measure of Ego Identity Status and the Parental Authority Questionnaire in addition to a biographic survey that included questions on their family structures (nuclear, extended, other types). Findings suggest that diffused and achieved identity statuses relate to perceived authoritative and permissive parenting styles respectively. Results bring into question the universality of Western identity development and parenting style theories.     

Culture,context and society – The underexplored potential of critical realism as a philosophical framework for theory and practice

This article explains how the meta‐theoretical framework of critical realism addresses methodological issues of concern to social psychologists and social scientists. The article outlines key tenets of critical realism – its notion of the stratified nature of reality and generative mechanisms as powers in natural and social objects that cause things; its notion of knowledge of reality as stratified rather than only empirical; its acceptance of epistemological but not judgmental relativism; and its monist ontology. The article then introduces realist social theory to provide a framework for understanding the society–person connection. It explains how issues relating to culture, context, and society raised in the indigenous psychology English literature might be addressed from a critical realist perspective. Some implications arising from adopting a critical realist perspective in research practice are outlined and social psychologists and social scientists are encouraged to explore the potential of critical realism as a meta‐theoretical framework and new paradigm.     

Divergence Behaviour of the Successive Geometric Mean Method of Pairwise Comparison Matrix Generation for a Multiple Stage,Multiple Objective Optimization Problem

This paper focuses on the divergence behaviour of the successive geometric mean (SGM) method used to generate pairwise comparison matrices while solving a multiple stage, multiple objective (MSMO) optimization problem. The SGM method can be used in the matrix generation phase of our three‐phase methodology to obtain pairwise comparison matrix at each stage of an MSMO optimization problem, which can be subsequently used to obtain the weight vector at the corresponding stage. The weight vectors across the stages can be used to convert an MSMO problem into a multiple stage, single objective (MSSO) problem, which can be solved using dynamic programming‐based approaches. To obtain a practical set of non‐dominated solutions (also referred to as Pareto optimal solutions) to the MSMO optimization problem, it is important to use a solution approach that has the potential to allow for a better exploration of the Pareto optimal solution space. To accomplish a more exhaustive exploration of the Pareto optimal solution space, the weight vectors that are used to scalarize the MSMO optimization problem into its corresponding MSSO optimization problem should vary across the stages. Distinct weight vectors across the stages are tied directly with distinct pairwise comparison matrices across the stages. A pairwise comparison matrix generation method is said to diverge if it can generate distinct pairwise comparison matrices across the stages of an MSMO optimization problem. In this paper, we demonstrate the SGM method's divergence behaviour when the three‐phase methodology is used in conjunction with an augmented high‐dimensional, continuous‐state stochastic dynamic programming method to solve a large‐scale MSMO optimization problem.

Examining the factor structure of the Psychological Mindedness Scale in the Japanese population through exploratory and confirmatory factor analyses

Psychological mindedness (PM) is a psychological construct that represents the tendency and ability to understand the relationships between thoughts, feelings, and behavior. This study examined the statistical properties, particularly the factor structure, of the Psychological Mindedness Scale (PMS) in a non‐clinical Japanese sample through exploratory and confirmatory factor analysis. The relationship between PMS and depression was also examined for predictive validity. The results suggested that the PMS tested on a Japanese sample contains the following four factors: (a) belief in the benefits of discussing one's problems; (b) access to feelings; (c) openness to new ideas and capacity to change; and (d) interest in the meaning and motivation of own and others' behavior. Whereas the total PM score and Factors 2 and 3 had negative correlations with depression, there was a positive correlation between Factor 4 and depression. The 4‐factor structure of the scale is deemed to be applicable to the Japanese population.     

Brain lateralization of complex movement: Neuropsychological evidence from unilateral stroke

Complex movement (CM) refers to the representation of a goal-oriented action and is classified as either transitive (use of tools) or intransitive (communication gestures). Both types of CM have three specific components: temporal, spatial, and content, which are subdivided into specific error types (SET). Since there is debate regarding the contribution of each brain hemisphere for the types of CM, our objective was to describe the brain lateralization of components and SET of transitive and intransitive CM. We studied 14 patients with a left hemisphere stroke (LH), 12 patients with a right hemisphere stroke (RH), and 16 control subjects. The Florida Apraxia Screening Test-Revised (FAST-R, Rothi et al., 1988) was used for the assessment of CM. Both clinical groups showed a worse performance than the control group on the total FAST-R and transitive movement scores (p < 0.001). Failures in Spatial and Temporal components were found in both clinical groups, but only LH patients showed significantly more Content errors (p < 0.01) than the control group. Also, only the LH group showed a higher number of errors for intransitive movements score (p = 0.017), due to lower scores in the content component, compared to the control group (p = 0.04). Transitive and intransitive CMs differ in their neurocognitive representation; transitive CM shows a bilateral distribution of its components when compared to intransitive CM, which shows a preferential left hemisphere representation. This could result from higher neurocognitive demands for movements that require use of tools, compared with more automatic communication gestures.
