Associations Between Preschoolers' Social–Emotional Competence and Preliteracy Skills

Identifying and understanding the predictors of preliteracy skills can set the stage for success in a child's academic career. Recent literature has implicated social–emotional competence as a potential component in helping children learn preliteracy skills. To further understand the role of social–emotional competence in preliteracy, the associations between various social–emotional competencies and preliteracy skills in 91 preschool children attending seven Head Start classrooms were examined. Results of structural equation modelling indicated that preschoolers' expressiveness/regulation (angry/aggressive, cooperative/sensitive or anxious/withdrawn) and emotion knowledge predicted preliteracy performance (alphabet knowledge and print and phonological awareness), above and beyond gender, age, maternal education, attentional abilities and classroom emotional support. These findings serve to broaden the research surrounding social–emotional competence and highlight its association with academic readiness. Copyright © 2015 John Wiley & Sons, Ltd.     

Performance and presence with head-movement produced motion parallax in simulated driving

Driving simulator studies can reveal relevant and valid aspects of driving behavior, but underestimation of distance and speed can negatively affect the driver’s performance, such as in performance of overtaking. One possible explanation for the underestimation of distance and speed is that two-dimensional projection of the visual scene disrupts the monocular-based illusory depth because of conflicting binocular and monocular information of depth. A possible solution might involve the strengthening of the monocular information so that the binocular information becomes less potent. In the present study, we used an advanced high-fidelity driving simulator to investigate whether adding the visual depth information of motion parallax from head movement affects sense of presence, judgment of distance and speed, and performance measures coupled with overtaking. The simulations included two types of driving scenario in which one was urban and the other was rural. The main results show no effect of this head-movement produced motion parallax on sense of presence, head movement, time to collision, distance judgment, or speed judgment. However, the results show an effect on lateral positioning. When initiating the overtaking maneuver there is a lateral positioning farther away from the road center as effect of the motion parallax in both types of scenario, which can be interpreted as indicating use of naturally occurring information that change behavior at overtaking. Nevertheless, only showing tendencies of effects, absent is any clear additional impact of this motion parallax in the simulated driving.     

Réalité virtuelle et santé des personnes âgées institutionnalisées. Vers un EHPAD 2.0 ?

Virtual reality (VR) is used in general health care: prevention, physical medicine, chronic and acute pain, quality of life in palliative care, and in psychiatry: anxiety, depression, addiction, psychosis. Our objective is showing VR using among elderly people in French retirement home. Virtual reality is showing efficacy as distraction, anti-pain, tranquillising, antidepressant methods. It should be an answer to many elderly health problems. VR is easy to use, with low side effects. Non-drug treatments among elderly people are recommended. Used as complementary or alternative medicine, VR must be shaped for using with old and fragile people in retirement home.
