Home environmental influences on children's language and reading skills in a genetically sensitive design: Are socioeconomic status and home literacy environment environmental mediators and moderators?

This twin study examined how family socioeconomic status (SES) and home literacy environment (HLE) contributes to Chinese language and reading skills. It included 312 Chinese twin pairs aged 3 to 11. Children were individually administered tasks of Chinese word reading, receptive vocabulary and reading‐related cognitive skills, and nonverbal reasoning ability. Information on home environment was collected through parent‐reported questionnaires. Results showed that SES and HLE mediated shared environmental influences but did not moderate genetic influences on general language and reading abilities. Also, SES and HLE mediated shared environmental contributions to receptive vocabulary and syllable and rhyme awareness, but not orthographic skills. The findings of this study add to past twin studies that focused on alphabetic languages, suggesting that these links could be universal across languages. They also extend existing findings on SES and HLE's contributions to reading‐related cognitive skills.     

Finding the Right Value: Framing Effects on Domain Experts

By defining the essence of a policy problem, an issue frame shapes how individuals think about a political issue. In this research, we investigate framing effects among domain experts, an understudied yet increasingly important set of individuals in the policymaking process. Because domain experts have extensive and highly structured knowledge on a particular topic, they are likely to actively process issue frames to which they are exposed. Consequently, we hypothesize that frames consistent with experts' values will be particularly influential, whereas frames inconsistent with their values will lead to contrast effects. We test our hypotheses on a unique set of domain experts by examining professional farmers' attitudes toward no‐till agriculture. Using an experimental design, we find evidence that environmental values interact with frames to influence farmers' interest in no‐till, especially when farmers are exposed to a novel frame.     

Can infrastructure improvements mitigate unsafe traffic safety culture: A driving simulator study exploring cross cultural differences

This paper presents the results of a cross-cultural study to investigate the influence of traffic safety culture and infrastructure improvements on driver behaviour. To achieve this, the driving style of UK drivers was compared with that of Nigerians with and without experience of driving in the UK. A driving simulator experiment compared the actual driving style of these three groups of drivers in different safety critical scenarios. The simulated road environment varied depending on how much infrastructure was provided (low or high infrastructure). In addition, the Driver Behaviour Questionnaire was used to collect self-reported data on violations, errors and lapses. It was hypothesised that Nigerian drivers with no experience of driving in a UK road system would report and engage in more unsafe driving behaviour compared to the other two groups, and that increasing infrastructure would have little positive benefit. Overall, the results supported these hypotheses, indicating that the behaviours of drivers are interpretable in relation to their traffic safety culture, compared to changes in their driving environment.     

Planet Braitenberg: Experiments in virtual psychology

Braitenberg vehicles are simple robotic platforms, equipped with rudimentary sensor and motor components. Such vehicles have typically featured as part of thought experiments that are intended to show how complex behaviours are apt to emerge from the interaction of inner control mechanisms with aspects of bodily structure and features of the wider (extra-agential) environment. The present paper describes a framework for creating Braitenberg-like vehicles, which is built on top of a widely used and freely available game engine, namely, the Unity game engine. The framework can be used to study the behaviour of virtual vehicles within a multiplicity of virtual environments. All aspects of the vehicle’s design, as well as the wider virtual environment in which the vehicle is situated, can be modified during the design phase, as well as at runtime. The result is a general-purpose simulation capability that is intended to provide the foundation for studies in so-called computational situated cognition—a field of study whose primary objective is to support the computational modelling of cognitive processes associated with the physically-embodied, environmentally-embedded, and materially-extended mind.     

Triangulating School Climate: Areas of Convergence and Divergence Across Multiple Levels and Perspectives

Students often have differing perceptions of their school's climate. Although these subjective perceptions can be meaningful outcome predictors, discrepancies create challenges for those seeking to globally characterize or intervene to improve the climate of a school. Trained, independent  observers can provide insights on perceptible and ostensibly malleable aspects of the school; however, the extent to which these observations help us to understand differences in students’ report of school climate has not been examined. To study this, we assessed convergence and divergence between independent observers’ assessments and students’ perceptions of school climate at the classroom and school levels. Data come from the Maryland Safe and Supportive Schools Initiative (MDS3), which included 20,647 students and observations of 303 teachers in 50 high schools. Students responded to survey items regarding safety, engagement, and environment; independent observers assessed teachers’ classroom practices and the school physical environment. A three-level model partitioned variance to the individual, classroom, and school levels. The variance in students’ climate perceptions was primarily between students, with most classroom and school intraclass correlation coefficients (ICCs) ranging from 0.01 to 0.08, though one was as high as 0.20; however, observations explained large percentages of between-school variation in climate (58%–91%). Findings suggest the potential utility of outside observations for explaining school-level variation in school climate to inform decision-making and future research.     

Caregivers can implement play-based instruction without disrupting child preference

Young children diagnosed with autism spectrum disorder often require systematic teaching to learn new skills, and caregivers can teach their children by embedding learning opportunities in a play-based context. However, researchers have not evaluated procedures to train caregivers how to implement a combination of strategies designed to establish rapport and early language skills while maintaining play as a preferred context. Caregiver–child dyads composed of 2 mothers and their sons were recruited to participate. A multiple-probe design across strategies was used to demonstrate the efficacy of behavioral skills training on the mothers' integration of parallel play, child-directed interaction, teaching requests (mands), and teaching labels (tacts). Both children acquired the target requests and labels as a function of their mothers' teaching. By assessing the children's preferences, we confirmed the teaching strategies did not decrease toy engagement or the value of playing with their mother. We obtained stimulus generalization of the mothers' implementation of the strategies from a clinic to their home and maintenance of mother and child performance across a month.     

Genetic and environmental influences on aggression in 4- to 7-year-old twins

Aggressive behaviors of 38 twin pairs (21 monozygotic [MZ], 17 dizygotic [DZ]) between the ages of 4 and 7 years were assessed through mothers' ratings and observations in their homes. An observation checklist was developed in which mothers were asked to observe and report each child's specific aggressive behaviors for a total of 6 hours spread over 3 days. In particular the observations focused on the following behaviors: rejection, destructiveness, negativism, noncompliance, teasing, physical negative, insult, verbal threat, and yelling. Biometrical genetic analysis evidenced significant heritable influences on composite aggression scores in both the observation checklist and the mothers' ratings; heritability estimates varied from.24 to.94 depending on the aggression nieasnre used, with scores from the mothers' observations demonstrating smaller genetic effect than those of the parental ratings of the environmental sources of variance, within-family factors were far more important than the between-family ones. The results also yielded significant sex and zygosity differences for means of some of the specific aggressive behaviors, where males and DZ twins scored higher than females and MZ twins. It was suggested that future studies should include more detailed investigations of the context in which specific aggressive behaviors occur and the sources toward which they are directed in order to determine the extent to which different types of aggression may have different etiologies.     

Autonomy support,basic need satisfaction and the optimal functioning of adult male and female sport participants: A test of basic needs theory

Grounded in Basic Needs Theory (BNT; Ryan and Deci, American Psychologist, 55, 68–78, 2000a), the present study aimed to: (a) test a theoretically-based model of coach autonomy support, motivational processes and well-/ill-being among a sample of adult sport participants, (b) discern which basic psychological need(s) mediate the link between autonomy support and well-/ill-being, and (c) explore gender invariance in the hypothesized model. Five hundred and thirty nine participants (Male = 271; Female = 268; M _age = 22.75) completed a multi-section questionnaire tapping the targeted variables. Structural Equation Modeling (SEM) analysis revealed that coach autonomy support predicted participants’ basic need satisfaction for autonomy, competence and relatedness. In turn, basic need satisfaction predicted greater subjective vitality when engaged in sport. Participants with low levels of autonomy were more susceptible to feeling emotionally and physically exhausted from their sport investment. Autonomy and competence partially mediated the path from autonomy support to subjective vitality. Lastly, the results supported partial invariance of the model with respect to gender.     

AN ISLAMIC APPRAISAL OF MINDING THE GAP

The neglect of psycho‐spiritual needs of patients as they traverse the modern healthcare system has been a featured theme in medical literature over the past decade. This literature, which often highlights in‐patient palliative care, as well as acute and critical care settings, influences practice guidelines and protocols of doctors and nurses. In this essay, I review some of the pertinent issues raised in the literature and examine the validity of placing an ethical perspective on this issue. I also compare Islamic theocentric perspectives with secular, non‐theistic perspectives on restoring psycho‐spiritual care for patients. I then develop a framework for pastoral intervention based on aspects of the Islamic tradition and elaborate this framework by addressing clinical contexts and cases. The essay is an exposition based upon a review of the modern medical literature, an analysis of some of the traditional Islamic written sources, and the observations of the investigator, a practicing physician and an American Muslim.
