Evaluating adult interaction during the Step It UP! game to increase physical activity in children

A recent intervention, the Step it UP! game (Galbraith & Normand, 2017), consists of an interdependent group contingency to increase student physical activity. In addition, previous research demonstrated that adult interaction may reinforce physical activity (Larson et al., 2014). We extended research on the Step it UP! game by comparing the effects of no game, Step it UP! game, and Step it UP! game plus adult interaction on the number of steps taken by participants in a third-grade classroom during recess. Overall, 19 of the 25 participants took more steps during the Step it UP! game plus adult interaction compared to the Step it UP! game and no-game recesses. Furthermore, 20 participants preferred the Step it UP! game plus adult interaction. Results suggest that adult interaction can enhance the effects of the Step it UP! game to increase physical activity.     

A combination of combat experience,early abduction,and severe traumatization fuels appetitive aggression and violence among abductees of rebel war in Northern Uganda

Individuals who perpetrate violence may likely perceive violence as appealing and infliction of violence to derive pleasure is termed as appetitive aggression. Individuals who were abducted as children into an armed group often experience a higher number of traumatic event types, that is traumatic load and are usually socialized in a violence-endorsing environment. This study aims to investigate the interaction between age at initial abduction with that of traumatic load, and their influence on appetitive aggression along with perpetration of violent acts by former members of an armed rebel group of both sexes. Semi-structured interviews were conducted among a target group of formerly abducted rebel-war survivors (including participants with and without combat experience) from Northern Uganda. Participants included 596 women and 570 men with N = 1,166 (M_age = 32.58, SD_age = 9.76, range: 18–80 years). We conducted robust linear regression models to investigate the influence of age at initial abduction, traumatic load, combat experience, and biological sex on appetitive aggression as well as their perpetrated violent acts. Our study shows, appetitive aggression and the number of perpetrated violent acts were specifically increased in individuals who were abducted young, experienced several traumatic events in their lifetime, and with previous combat experience. For perpetrated violence men showed increased levels whereas for appetitive aggression the association was independent of biological sex. Therefore, early abducted individuals with a higher traumatic load, who have combat experience, need to be given special intervention to prevent any further violence.     

Antecedents of fathers’ perception of child behavior at child age 12 months

This study investigates whether fathers’ adverse childhood experiences (ACE) and attachment style reported during pregnancy predict fathers’ perception of child behavior assessed 12 months postpartum, expressed by the Parenting Stress Index (PSI), Child Domain. Prospective fathers (N = 835) were recruited to “The Little in Norway (LiN) study” (Moe & Smith) at nine well-baby clinics in Norway, with data collection composed of five time points during pregnancy and two time points postpartum (6 and 12 months). The main analyses included linear regression, path-analysis modeling, and intraclass correlation based on mixed effects modeling. First, linear regression analyses showed that neither fathers’ ACE nor attachment style significantly predicted perceived child behavior postpartum directly. Furthermore, path analyses showed that ACE and less secure attachment style (especially avoidant attachment) measured early in pregnancy strongly predicted negatively perceived child behavior, mediated by fathers’ mental health symptoms during pregnancy and partner disharmony postpartum. Second, intraclass correlation analyses showed that fathers’ perceived child behavior showed substantial stability between 6 and 12 months postpartum. Family interventions beginning in pregnancy may be most beneficial given that fathers’ early experiences and perceptions of attachment in pregnancy were associated with later partner disharmony and stress.     

Metacognitive components of writing: Construction and validation of the Metacognitive Components of Planning Writing Self-inventory (MCPW-I)

IntroductionWriting and metacognition play an essential function in the learning process, in that writers engage arduous cognitive efforts by selecting and organizing ideas, then reviewing and readjusting them.ObjectiveThe present research aimed to construct and validate a self-report instrument to measure some specific metacognitive processes implicated in writing planning. Two categories of metacognitive components were considered: metacognitive knowledge and self-regulation strategies.MethodBased on exploratory and confirmatory analyses, the Metacognitive Components of Planning Writing Self-inventory (MCPW-I) was constructed and validated. This instrument is composed of three factors: Metacognitive Conditional Knowledge – MCK (6 items), Covert Self-regulation – CSF (4 items), and Environmental self-regulation – ESF (5 items). 1022 undergraduates students engaged in various programs of a French university filled in the inventory.ResultsThe alpha coefficients indicated a reliable internal consistency and the test-retest reliability showed a good temporal stability. Correlational analyses revealed that the CRS factor was related to ESR and MCK factors, and these last two were not correlated with each other. After the analysis of variance, the responses relative to ESR and MCK dimensions differed according to gender, but no differences relatively to the academic disciplines considered was found. Concerning the predictive validity, CSF and MCK were correlated with writing performance.ConclusionThe results confirm the validity and reliability of the MCPW-I which constitutes a new research tool for the study of metacognitive processes of writing.     

Differential association between food craving,food addiction and eating-related characteristics in persons at risk for eating disorders

IntroductionFood craving is a key feature of eating disorders, but its association with medical and psychological outcome might depend on the type of eating disorder.ObjectivesThis study investigated the factors associated with food craving in individuals at risk for DSM-5 eating disorder.MethodSeventy-six women were recruited from a non-clinical population (n = 372) based on their positive screening (EDDS, QEWP-R) for binge eating disorder (BED; n = 29), anorexia nervosa (AN; n = 28) or bulimia nervosa (BN; n = 19). They completed self-administered questionnaires assessing food craving (FCQ- T-r), Body Mass Index (BMI), eating behaviour (DEBQ), food addiction (YFAS 2.0), and anxiety and depressive symptoms (HADS).ResultsIndividuals at risk for BED or BN had higher food craving than those at risk for AN. Food craving was associated with BMI only in the BED group. Food craving was positively correlated with external eating in all groups, and with emotional eating in the AN and BED groups and correlated with anxiety only in BN. Food addiction prevalence was higher in the BN group than in the AN or BED groups (respectively 94.7%, 46.4% and 65.5%; p < 0.01). In this non-clinical population, we demonstrated that food craving was differentially associated with BMI and eating-related characteristics according to the type of eating disorder.ConclusionThis suggests that food craving is a transdiagnostic dimension that should be differentially targeted depending on the type of eating disorder; future studies should test this hypothesis in clinical populations.     

Attachment and resource sharing

In three studies we examined the associations between resource sharing (RS) and attachment, and the enhancement of RS using attachment security primes. In Study 1, we showed that attachment avoidance was negatively associated with RS. We also identified differences and similarities between RS and pro‐sociality. In Studies 2 and 3, we showed that research participants were more likely to share their monetary resources after they were primed with attachment security. Study 3 further revealed that security priming affected mainly people low on state attachment anxiety. Our findings extend previous work on pro‐sociality into the specific realm of RS, provide behavioral evidence, and tie attachment and close relationships in with game theory and research on economic decision making.     

Investigating route learning,metacognition, and beacon-based strategies using virtual environments

IntroductionDominant theories of wayfinding may have underestimated the ease with which adults can learn a route, even with minimal exposure to that route.ObjectivesIn this paper we present three different experiments to provide a comprehensive picture of whether adults can learn complex routes consisting of a number of choicepoints, and if so, what strategies they might be employing to do so.Methodand results We found that adults could learn a 15-junction route after only a single experience of the route (Experiment 1) but that they underestimated how good they would be at learning the 15-junction route (Experiment 2). In Experiment 3, we found that when learning a route made up of “T” shaped junctions, participants relied on a “beacon” strategy based on visual matching.ConclusionsCollectively, these findings suggest that adults can learn complex routes, even with as many as 15 choicepoints, very quickly and without the need for repeated exposure. These findings have implications for theories of wayfinding and call into question the need for repeated exposure.     

Personal values and unsanctioned aggression inherent in contact sports: The role of self-regulatory mechanisms,aggressiveness, and demographic variables

IntroductionTo date, research-examining factors related to the sociocognitive self-regulatory mechanisms governing unsanctioned aggression have received scant attention in applied sport psychology.ObjectiveA mediating model as influenced by various demographic variables was applied to explore the relationships between athletes’ personal values and their unsanctioned aggression directly and indirectly through the mediating role of resistive self-regulatory efficacy, moral disengagement, and aggressiveness.MethodA sample of 301 French competitors of different age (young: n = 200 and adult: n = 101), gender (male: n = 172 and female: n = 129), type of sport (high: n = 131 and low contact: n = 170), level of competition (beginner: n = 115, intermediate: n = 110, and advanced: n = 76), and length of practice (brief: n = 109, intermediate: n = 49, and extensive: n = 143) completed a questionnaire assessing the aforementioned variables.ResultsStructural equation modelling demonstrates that self-transcendence and self-enhancement values have only indirect negative and positive effects, respectively, on unsanctioned aggression through the full mediating effect of the mediators. Also, age, gender, and type of sport were predictive only of some personal values and mediators.ConclusionThese findings offer evidence that resistive self-regulatory efficacy, moral disengagement, and aggressiveness are mediators that fully govern the impact of athletes’ personal values and certain demographic variables on their unsanctioned aggression. Several limitations, implications and suggestions for further research are discussed.     

演绎推理的形式和内容启动加工

聚焦推理加工初期,研究通过指导语操控主观加工倾向,考察不同指导语条件下内容可信度和形式有效性对演绎推理结果的影响,检验内容和形式两类加工过程的启动加工动态变化性。结果表明,指导语条件显著影响推理初期加工。在无提示指导语和形式判定指导语条件下,推理结果受到了形式有效性和内容可信度的影响;内容判定指导语下只受到了内容可信度的影响。证明主观加工倾向影响了内容和形式的启动加工关系,支持了动态变化性的假设。     

社会距离和性别对公平关注的影响

本研究使用单次匿名最后通牒博弈任务,采用2（性别: 男性, 女性）×3（社会距离: 自我决策, 替朋友决策, 替他人决策）×5（提议类型: 1/9, 2/8, 3/7, 4/6, 5/5）的混合实验设计,通过操作反应者的不同社会距离,考察资产分配情境下自我-他人决策的性别差异。研究结果发现：（1）相比于自我决策和替朋友决策,女性被试替他人决策时更愿意接受提议1/9,2/8和3/7,而提议4/6和5/5的接受率不受社会距离的影响;男性被试中社会距离和提议类型的交互作用不显著;（2）不平等提议的反应时随社会距离增加而逐渐降低,而平等提议的反应时不受社会距离的调节;（3）替他人决策时女性的接受阈限显著低于男性,而自我决策及替朋友决策时接受阈限不存在性别差异。
