Three- to Four-Year-Old Children Rapidly Adapt Their Predictions and Use Them to Learn Novel Word Meanings

Adults create and update predictions about what speakers will say next. This study asks whether prediction can drive language acquisition, by testing whether 3- to 4-year-old children (n = 45) adapt to recent information when learning novel words. The study used a syntactic context which can precede both nouns and verbs to manipulate children's predictions about what syntactic category will follow. Children for whom the syntactic context predicted verbs were more likely to infer that a novel word appearing in this context referred to an action, than children for whom it predicted nouns. This suggests that children make rapid changes to their predictions, and use this information to learn novel information, supporting the role of prediction in language acquisition.     

Opinion mining in social media: Modeling,simulating, and forecasting political opinions in the web

Affordable and ubiquitous online communications (social media) provide the means for flows of ideas and opinions and play an increasing role for the transformation and cohesion of society – yet little is understood about how online opinions emerge, diffuse, and gain momentum. To address this problem, an opinion formation framework based on content analysis of social media and sociophysical system modeling is proposed. Based on prior research and own projects, three building blocks of online opinion tracking and simulation are described: (1) automated topic, emotion and opinion detection in real-time, (2) information flow modeling and agent-based simulation, and (3) modeling of opinion networks, including special social and psychological circumstances, such as the influence of emotions, media and leaders, changing social networks etc. Finally, three application scenarios are presented to illustrate the framework and motivate further research.

Effects of Alternated Basketball Competition on Perceived Competence in Adolescents with Intellectual Disabilities Over a Period of 13 Months: A research note

The purpose of this study was to examine the effects of alternated (segregated and integrated) basketball competition on two domains of perceived competence and on general self-worth. Participants were 24 adolescent males with intellectual disabilities divided equally into three groups: (a) those involved in basketball in an alternated sport competition, (b) those involved in adapted physical activity, and (c) those who were sedentary. The experimental treatment lasted for 13 months. For the sport competition group this involved 2 hr of training each week and 12 competitive meets. We administered Harter's (1985) Self-Perception Profile for Children 13 times to determine changes in perceived competence and general self-worth. The results indicate no significant changes for the different groups in the two domains of perceived competence and in general self-worth over 13 months.     

Preliminary study on the role of alternative educational pathways in promoting the use of problem-focused coping strategies

Coping styles are generally considered to be environmentally driven. Up to now, research has mainly focused on family influences. However, some studies underline the effect of educational settings on the development of problem-focused coping strategies. Consistently with previous reports on the enhancement of autonomy and problem-solving in alternative schools, and the relationship established by self-determination theory between autonomy-supportive climates and positive coping, we hypothesized that alternative school students develop more problem-focused coping styles. This hypothesis was tested on 80 traditional school students and 50 alternative school students (Steiner, Montessori and New schools), during their last secondary school year, using the Coping Inventory for Stressful Situations (Endler & Parker, 1990a). We also assessed psychological factors which can influence coping styles measures (anxiety and depression), using the State-Trait Anxiety Inventory (Spielberger, 1983), and the Beck Depression Inventory (Beck, Ward, Mendelson, Mock, & Erbaugh, 1961). The proportion of problem-focused coping strategies was compared in traditional and alternative settings, adjusting for potential confounding factors, using logistic regression. Results show that the proportion of students using predominantly problem-focused coping strategies is higher in the population of alternative schools. Directions for further research on alternative schools are highlighted concerning coping as well as autonomy-supportive class climates.     

Validity and reliability of the Very Short form of the Physical Self-Inventory among Turkish adolescents

The study aimed to test the validity and reliability of the Very Short form of the Physical Self-Inventory (PSI-VS) among a sample of 635 Turkish adolescents. These adolescents have completed the 12 original items of the PSI-VS, plus a positively worded reformulation of the single reverse-keyed item of the physical attractiveness subscale. A series of confirmatory factor analyses was used to examine the psychometric properties of the original and modified versions of the PSI-VS. Findings revealed superior psychometric properties with the modified version than with the original set of items. The modified version was thus subsequently used to examine its factor structure invariance across sexes, age groups and sport practice involvement. Results not only report that this version was fully invariant across, but also that latent means were significantly different across sexes and sport practice involvement. In sum, the Turkish modified version of the PSI-VS presents acceptable psychometric properties and may be used to repeatedly and/or intensively assess participants’ physical self-perceptions in the context of sport and exercise interventions.     

Predicting the use of single versus multiple types of violence towards children in a representative sample of Quebec families

OBJECTIVE: The purpose of this study is to determine which factors best predict parental use of single versus multiple types of violence. METHODOLOGY: The study uses data from a Quebec telephone survey conducted with a representative sample of 2,469 mothers of children aged 0-17 years. The interview covered topics such as mother's attitudes and reports of violence towards children, mother's experiences of childhood violence, level of marital discord, and socioeconomic factors. A discriminant function analysis was performed using individual and family factors to predict membership in five distinct groups: (a) no violence reported; (b) reports of psychological aggression only; (c) reports of minor physical violence only; (d) reports of psychological aggression and minor physical violence; and (e) reports of psychological aggression, minor and severe physical violence. RESULTS: One-way ANOVAs revealed that the groups differed significantly on factors such as child's age and gender, mother's attitudes, mother's experiences of childhood violence, level of marital discord, and number of children in the household. Discriminant function analysis revealed that the groups differed in two ways. The first function maximally separated the report of psychological aggression from minor physical violence only. The second function discriminated between the combined reports of all three types of violence versus the reports of minor physical violence only. Mother's attitudes and experiences of childhood violence were the two factors that best distinguished among groups and best predicted group membership. CONCLUSION: These results offer new insights for the prediction of mother's reports of one type versus multiple types of violence and highlight the importance of distinguishing between types and combinations of family violence in future research.     

Teacher–Student Relationship Quality and Children's Bullying Experiences With Peers: Reflecting on the Mesosystem

Drawing from social–ecological systems theory, the authors argue that -current research on childhood bullying would benefit from analyses that consider the -mesosystem—specifically, how teacher–student relationships can influence -children's bullying experiences. The authors provide two theoretical conceptions for how children's peer interactions are implicitly shaped by teacher–student relationship quality: attachment and social referral. Implications for practice, with an emphasis on developing teachers' social–emotional competencies to strengthen positive teacher–student relationships, are proposed.     

Lumbopelvic motor control and low back pain in elite soccer players: a cross-sectional study

This study aimed to investigate the relationship between the history of low back pain and quality of lumbopelvic motor control in soccer players. Forty-three male elite soccer players (mean age, 18.2 ± 1.4 years) filled in questionnaires related to low back pain and attended a session to assess lumbopelvic motor control by means of five tests (the bent knee fall out test, the knee lift abdominal test, the sitting knee extension test, the waiter’s bow and the transversus abdominis test). A physiotherapist, blinded to the medical history of the participants, scored (0 = failed, 1 = correct) the performance of the players for each of the tests resulting in a lumbopelvic motor control score ranging from 0 to 5. Forty-seven per cent of the soccer players reported a disabling low back pain episode lasting at least two consecutive days in the previous year. These players scored worse lumbopelvic motor control than players without a history of low back pain (lumbopelvic motor control score of 1.8 vs. 3.3, P < 0.01). The between-groups difference was particularly marked for the bent knee fall out test, the knee lift abdominal test and the transversus abdominis test (P < 0.01). In conclusion, most soccer players with a history of low back pain had an altered lumbopelvic motor control. Further research should examine whether lumbopelvic motor control is etiologically involved in low back pain episodes in soccer players.
