Geographic region effects on adolescent physical self: An exploratory study

The objectives of this exploratory study were to examine gender differences in physical self‐concept, and the influence of geographic place of residence on both adolescents' physical self‐concept and gender differences in physical self‐concept. The Physical Self Inventory was used to measure physical self‐perceptions and global self‐esteem. Participants were 323 boys and 282 girls living in the North or South of France. First a Mann‐Whitney U test was used to assess gender differences and the influence of geographic region differences on physical self‐perceptions (physical self‐worth, physical condition, sport competence, attractive body, physical strength) and global self‐esteem. Then a Kruskal‐Wallis ANOVA for ranked data was used to assess geographic region influence on boys' and girls' physical self‐concept and global self‐esteem. The results showed that not only did boys have significantly higher physical self scores (on all scales) and global self‐esteem than girls, but also that adolescents from the North of France had higher physical self scores (on all scales) and global self‐esteem than adolescents from the South. Moreover, many differences were found between boys and girls on physical self scores (on all scales) and global self‐esteem according to their geographic place of residence. The main results showed that girls from the South had lower scores on the attractive body, physical strength, physical self‐worth, and global self‐esteem scales than all other adolescents, and that boys from the South had lower scores on the attractive body and global self‐esteem scales than did boys and girls from the North.     

Contributions of teacher-child relationships to positive school adjustment during elementary school

The current study examined the extent to which teacher-child relationship contributed to school adjustment among 1310 elementary school-aged students and the degree to which this relationship was moderated by significant child characteristics. The results suggest a consistent and comparable effect for children across grades, gender, and types of school outcomes. Children experiencing behavioral or learning problems showed poorer school outcomes and were less able to benefit from a close teacher relationship when compared to peers without such problems. However, a protective effect was noted, such that children with developmental vulnerabilities and a close teacher relationship were significantly advantaged relative to similarly affected peers who lacked such relationships. The results are discussed in light of research and theory, and applications are made to school-based practices.     

The Effects of Numbered Heads Together with and Without an Incentive Package on the Science Test Performance of a Diverse Group of Sixth Graders

A clear and consistent finding of educational research has been the importance of active student responding. During lectures and discussions, active responding most often takes the form of student responses to teacher questions. This whole group responding to questions, however, does not permit every student to respond and does not assure that all students are actively engaged. Previous research has shown that Numbered Heads Together is an efficient and effective instructional technique to increase student responding and to improve achievement. Using an A-B-BC-B-BC design, we examined the effects of two versions of Numbered Heads Together on 6th graders daily quiz scores and pretest-posttest performance in chemistry. Findings indicated that the addition of a behavioral incentive package noticeably improved student performance during Numbered Heads Together instruction. Implications are discussed for teachers and educational researchers.     

Attachment and sensitivity in family context: the roles of parent and infant gender

This study examined the role of child gender in fathers' and mothers' sensitivity to and attachment relationships with their infants from a family systems perspective. Eighty‐seven 1‐year‐olds participated in the Strange Situation with each parent. Parental sensitivity was examined during a competing demands task. Results indicated that fathers and mothers were equally sensitive to sons, but fathers were less sensitive than mothers to daughters, and mothers were more sensitive to daughters than to sons. Although mothers and fathers within the same families were similarly sensitive to daughters and sons, daughters' attachment security with fathers and mothers was similar whereas sons' was not. Further analyses revealed that fathers were more sensitive to sons with an insecure relationship with their mothers. Results of this investigation suggest that child gender is relevant for parent–infant, especially father–infant, attachment relationships. Copyright © 2006 John Wiley & Sons, Ltd.     

The role of production abilities in the perception of consonant category in infants

The influence of motor knowledge on speech perception is well established, but the functional role of the motor system is still poorly understood. The present study explores the hypothesis that speech production abilities may help infants discover phonetic categories in the speech stream, in spite of coarticulation effects. To this aim, we examined the influence of babbling abilities on consonant categorization in 6‐ and 9‐month‐old infants. Using an intersensory matching procedure, we investigated the infants’ capacity to associate auditory information about a consonant in various vowel contexts with visual information about the same consonant, and to map auditory and visual information onto a common phoneme representation. Moreover, a parental questionnaire evaluated the infants’ consonantal repertoire. In a first experiment using /b/–/d/ consonants, we found that infants who displayed babbling abilities and produced the /b/ and/or the /d/ consonants in repetitive sequences were able to correctly perform intersensory matching, while non‐babblers were not. In a second experiment using the /v/–/z/ pair, which is as visually contrasted as the /b/–/d/ pair but which is usually not produced at the tested ages, no significant matching was observed, for any group of infants, babbling or not. These results demonstrate, for the first time, that the emergence of babbling could play a role in the extraction of vowel‐independent representations for consonant place of articulation. They have important implications for speech perception theories, as they highlight the role of sensorimotor interactions in the development of phoneme representations during the first year of life.     

Emerging research on intergroup prosociality: Group members' charitable giving,positive contact,allyship, and solidarity with others

This paper describes an emerging body of work on intergroup prosociality, drawing together parallel literatures and highlighting some of the themes of the recent research. A broad distinction between benevolence and activism serves as the foundation to explore forms of intergroup prosociality, such as charitable giving, displays of empathy and affirmation (positive and supportive contact), allyship, and solidarity. Gaps and implications for future research are discussed. For example, we propose that it may be useful to distinguish allyship, defined as advocacy for others motivated by the values and norms of the ingroup for its own ends, from solidarity, defined as advocacy on behalf of others from the perspective of a shared, inclusive group. We propose that articulating the similarities between these various forms of intergroup prosociality, and testing the differences, will be a useful direction of future research.

Effects of cognitive impairment on prosodic parameters of speech production planning in multiple sclerosis

Cognitive impairment (CI) affects 40–65% of patients with multiple sclerosis (MS). CI can have a negative impact on a patient's everyday activities, such as engaging in conversations. Speech production planning ability is crucial for successful verbal interactions and thus for preserving social and occupational skills. This study investigates the effect of cognitive-linguistic demand and CI on speech production planning in MS, as reflected in speech prosody. A secondary aim is to explore the clinical potential of prosodic features for the prediction of an individual's cognitive status in MS. A total of 45 subjects, that is 22 healthy controls (HC) and 23 patients in early stages of relapsing-remitting MS, underwent neuropsychological tests probing specific cognitive processes involved in speech production planning. All subjects also performed a read speech task, in which they had to read isolated sentences manipulated as for phonological length. Results show that the speech of MS patients with CI is mainly affected at the temporal level (articulation and speech rate, pause duration). Regression analyses further indicate that rate measures are correlated with working memory scores. In addition, linear discriminant analysis shows the ROC AUC of identifying MS patients with CI is 0.70 (95% confidence interval: 0.68–0.73). Our findings indicate that prosodic planning is deficient in patients with MS-CI and that the scope of planning depends on patients’ cognitive abilities. We discuss how speech-based approaches could be used as an ecological method for the assessment and monitoring of CI in MS.

A Meaningful Justification for the Representational Theory of Measurement

Measurement, the means by which numbers enter science, is of fundamental importance to modern science. The relationship between its qualitative and quantitative aspects has generated many theories and much controversy. In 19th century geometry similar developments led mathematician Felix Klein to devise a theory for unifying qualitative and quantitative approaches to geometry. Klein's theory, which today is called the Erlanger program, was based on transformation groups. In this article, the Erlanger program is given a new foundation based on mathematical logic and is extended to science. The current dominant theory of measurement in the literature, the representational theory, is then justified in terms of the new foundation for the Erlanger program. Certain inferential techniques used in dimensional analysis and the related technique of possible psychophysical laws are also given justifications in terms of the new foundation.
