Executive functions,impulsivity, and inhibitory control in adolescents: A structural equation model

Background. Adolescence represents a critical period for brain development, addressed by neurodevelopmental models to frontal, subcortical-limbic, and striatal activation, a pattern associated with rise of impulsivity and deficits in inhibitory control. The present study aimed at studying the association between self-report measures of impulsivity and inhibitory control with executive function in adolescents, employing structural equation modeling. Method. Tests were administered to 434 high school students. Acting without thinking was measured through the Barratt Impulsiveness Scale and the Dickman Impulsivity Inventory, reward sensitivity through the Behavioral Activation System, and sensation seeking through the Zuckerman–Kuhlman–Aluja Personali- ty Questionnaire. Inhibitory control was assessed through the Behavioral Inhibition System. The performance at the Wisconsin Card Sorting Task indicated executive function. Three models were specified using Sample Covariance Matrix, and the estimated parameters using Maximum Likelihood. Results. In the final model, impulsivity and inhibitory control predicted executive function, but sensation seeking did not. The fit of the model to data was excellent. Conclusions. The hypothesis that inhibitory control and impulsivity are predictors of executive function was supported. Our results appear informative of the validity of self-report measures to examine the relation between impulsivity traits rather than others to regulatory function of cognition and behavior.     

Impact of Well-being Interventions for Siblings of Children and Young People with a Chronic Physical or Mental Health Condition: A Systematic Review and Meta-Analysis

Siblings of children and young people with a chronic illness are at increased risk of poor psychological functioning. A number of studies have attempted to implement and evaluate interventions targeting the psychological well-being of this at-risk group. This systematic review summarises the evidence regarding psychological functioning of siblings following an intervention targeting their well-being. The meta-analysis considered behaviour and knowledge, two of the most frequently studied outcomes. The following databases were used: PsycINFO, EMBASE, CINAHL, PubMed, Scopus and Web of Science. Seventeen studies were eligible to be included in the systematic review and eight in the meta-analysis. Results from the systematic review reflected the inconsistency of intervention evaluations in this area with a high level of heterogeneity and a total of 23 outcomes considered across the 17 included studies. The meta-analysis estimated effect sizes using a standardised mean difference (SMD) approach. Pre-post analysis suggested significant improvement in behavioural outcomes and knowledge of their sibling’s health conditions with a SMD of ? 0.44 [95% CI (? 0.6, ? 0.29); p = 0.000] and 0.69 [(95% CI = 0.42, 0.96); p = 0.000], respectively. The SMD was not significant for behavioural outcomes when considering treatment–control studies. In conclusion, the findings suggest interventions for well-being have a positive effect on the psychological functioning of siblings of children and young people with a chronic illness, but their specificity needs to be established. There is a need for further, more methodologically robust research in this area.     

Is two better than one? Comparing children’s narrative competence in an individual versus joint storytelling task

This research looks at the potential of peer interaction practices in improving narrative competence by analyzing the efficacy of peer learning on children’s oral narrative productions. Gains on a macro-level (structure and coherence of the narrative) and a micro-level (cohesion of the narrative) were analyzed. Fifty-six primary school children participated in this study. Each child told a narrative either individually (individual condition) or while interacting with a peer (joint condition). We explored whether children produced longer, more structured, coherent and cohesive narratives in a joint condition rather than individually, and in which condition the joint task was more beneficial for children’s narrative competence in terms of narrative scores in the individual condition, discrepancy between the members of the same pair, and quality of the interaction. The advantage of peer learning does not derive from the direct comparison of the individual versus the joint condition but depends on specific conditions: the joint condition was beneficial for individuals with lower individual competence and for pairs with a high discrepancy between individual scores. Children’s quality of interaction did not seem to influence the efficacy of peer learning on their narrative competence.     

Kindergarteners' Narrative Competence Across Tasks and Time

The authors investigated children's narrative competence by analyzing the development of the reciprocal relationship between storytelling and story retelling performances over a school year through a cross-lagged panel design. The participants in this study were 170 Italian kindergarten pupils (M age = 4.98 ± 0.31 years). Children were asked to produce oral narratives in two different tasks: a storytelling and a story retelling task. Narrative competence was assessed in terms of structure and coherence. The cross-lagged panel analyses showed that both storytelling and story retelling tasks are stable constructs, but they differ in the emphasis on coherence. Data confirmed the pivotal role played by storytelling as a task, and structure as a component in fostering the development of children's narrative competence. Overall, results from this study suggest that storytelling and story retelling are tasks that involve interrelated but not overlapping processes, and trigger different aspects of narrative competence.     

Estimating One's Own and Others' Multiple Intelligence: A Cross-Cultural Study from Guinea Bissau and Portugal

This study examined the estimations of multiple intelligences for self, partner and parents. One hundred and fifty two students (males = 81, females = 68, and 3 have not indicated their sex; mean age = 24.02, SD = 3.08) from Guinea Bissau estimated their own, their partners', and their parents' IQ scores on each of Gardner's ten multiple intelligences: verbal (linguistic), logical (mathematical), spatial, musical, body-kinesthetic, interpersonal, intrapersonal, existential, spiritual and naturalistic. In contrast to previous results (A. Furnham, 2001) sex differences in self-estimates did not occur in this Guinean sample. Participants rated overall intelligence of their father higher than that of their mother. An existing data set on estimates of intelligence in a Portuguese sample was used for a cross-cultural comparison between Portuguese and Guinean participants. There were consistent and clear culture differences. Guinean gave higher self, partner and family ratings than Portuguese. Results are discussed in terms of the growing literature in the self-estimates of intelligence, as well as limitations of that approach.     

Static items are automatically prioritized in a dynamic environment

Everyday experience provides us with the intuition that dynamic events guide or capture attention—something which has been confirmed in experimental studies. Recently, we showed that there are limitations to the extent to which dynamic items attract attention. In a visual search task where all items, except one, were dynamic, the dynamic items could be ignored and the static item could be efficiently detected. In the present study we investigated whether attention is automatically drawn to the static item. Three visual search experiments, in which the target and the static object were uncorrelated, revealed that the static item was nevertheless prioritized. This result is at odds with some of the current theories on attentional capture, including the “new object” hypothesis. The current study suggests that differences in dynamics, rather than dynamic features per se, determine where attention is allocated.     

Describing organizations as reinforcer systems: A new use for job satisfaction and employee attitude surveys

Job satisfaction data on managerial personnel were used to illustrate how organizations can be differentiated and described as reinforcer systems. Twenty-seven specific satisfaction scales were regressed on overall job satisfaction, separately for each of five groups of managers from five organizations. For all groups, overall satisfaction was found to be determined mainly by scales concerning challenge of the job and prospects of one's chosen career. Application of decremental stepwise multiple regression procedures to obtain minimum-variable-set equations resulted in different, though overlapping, sets of variables in the equations for the different organizations. These results suggest a way of describing organizations as reinforcer systems, in terms of the specific determinants of overall satisfaction for the organization.     

Job demands,coping, and impacts of occupational stress among journalists: a systematic review

This paper systematically reviews empirical research published from 2002 to July 2015 investigating journalists’ occupational stressors, coping strategies, and the impacts of these variables on the health and well-being of such professionals, whether on their daily work or as special envoys to critical scenarios. A meta-analytic approach was displayed to analyse the association between exposure to traumatic events during work and journalists’ symptoms of post-traumatic stress disorder (PTSD). Twenty eight articles met the inclusion criteria and revealed that very few studies distinguish (and none compare) the distress of journalists in their daily work from the distress of reporting major disasters, not a single study addressed positive emotional responses and only one research study focused on an in-depth analysis of the most commonly used coping strategies by journalists. The impacts of occupational stress among these professionals were sorely negative (e.g., burnout, PTSD), and no study was found to address the design and assessment of preventive interventions for these impacts on the health and well-being of journalists. Thirteen studies were included in a random-effects model meta-analysis and a small to moderate effect size (r = 0.272) between exposure to traumatic events during assignments and PTSD was found. The article closes with directions for future studies.
