Sex differences in the estimated intelligence of school children

This study investigated sex differences in estimated general and multiple intelligence in school children, their parents, and their teachers. There were three groups of participants: 285 (149 female, 136 male) pupils of a mixed government‐run comprehensive school, between the ages of 13 and 16 years; 93 mothers and 58 fathers of the pupils; and five female and eight male teachers. Children estimated their own and their parents' IQ, whilst the parents estimated their own and their children's IQ; the teachers estimated only the children's intelligence. The aims of this study were firstly to assess whether perceptions of male intellectual superiority were observable in school age children and school teachers, and to make direct comparisons between the children's self‐estimations and those of the parents and the teachers. Secondly, this study aimed to replicate previous literature on adult self‐estimations of overall and multiple intelligences, and to compare these to estimations by children of these adults (their parents). Fewer sex differences were observed than expected. Teachers' estimations did not follow conceptions of male superiority. The patterns of sex differences in mother and teacher estimations of children were similar to each other, as were those of fathers and children. Verbal and numerical abilities were found to be most closely related to estimations of overall IQ in all three groups. Most striking was the lack of correlation between father and daughter estimations of each other. Reasons why this study failed to replicate findings on adult samples are discussed.

Ethnicity,school attitudes,intelligence and academic achievement

Regression surface analysis was used to examine relations between school-related attitudes and measures of academic achievement at different levels of intellectual ability, for children from different Australian ethnic groups. The sample included 660 eleven-year-old children from lower social status families, with 250 Anglo Australian children, 170 Greek, 120 Southern Italian, and 120 English children. Regression surfaces were constructed from models that examined possible linear, interaction, and curvilinear relations between the variables. The findings suggest the propositions that: (a) at each level of intelligence, increases in the affective component of school attitudes are not associated with changes in academic achievement, (b) at each level of the affective component of school attitudes, increments in intelligence test scores are related to increases in academic achievement scores, and (c) the relations between academic achievement, intelligence, and the cognitive-behavioral component of school attitudes vary for children from different ethnic groups. The results suggest that the manipulation of the cognitive-behavioral aspects of school attitudes may influence the academic performance of low social status children from different ethnic groups but educational programs that focus on the affective components of school attitudes may not be effective in changing children's academic achievement.     

Race, brain size, and intelligence: another reply to Cernovsky

Five sets of observations require explanation. Firstly, within both black and white populations there is a small positive correlation between IQ and brain size whether or not there is control for body size. Secondly, racial differences in average brain size occur such that Mongoloids greater than Caucasoids greater than Negroids especially with control for body size. Thirdly, mammals with larger brains relative to their bodies perform better on learning tasks than mammals with smaller brains relative to their bodies. Fourthly, average racial differences on measures of cognitive performance parallel the differences in average brain size. Fifthly, average racial differences on numerous other traits parallel the differences in intelligence and brain size. It is incumbent on scientists to explain these facts.     

Holistic face processing among school children,younger and older adults

While previous studies have mostly examined holistic face processing in childhood and young adulthood, the present study investigated developmental changes of holistic face processing under a lifespan perspective, including older adulthood. Children 5–7 and 9–10 years of age, as well as young and older adults were instructed to assign faces into two categories. The categories were constructed to allow either a holistic categorization according to the overall face similarities or an analytical categorization by focusing on single facial features. The results show an increase in holistic face processing from childhood to young adulthood and a decrease towards older adulthood. Features used for categorization changed from internal to external features with age. Thus, crucial changes of face processing occur beyond young adulthood.     

The relationship between personality and bullying among primary school children: the mediation role of trait emotion intelligence and empathy

Background/ObjectivesSeveral studies have shown that personality traits are a benchmark in research field of bullying prevention, while others have highlighted that the socio-emotional skills are important to prevent a wide range of maladjusted behaviors, suggesting that the investment in their developing may mediate the effects of personality dispositions. The present study aims to clarify if socio-emotional attitudes can mediate the relationships between personality traits and bullying.MethodsFive sequential mediation models are tested using the Big Five personality traits as focal predictors, bullying as the outcome, and trait emotional intelligence and empathy as causally chained mediators, involving 199 primary school children (8-10 years) through the Bullying Prevalence Questionnaire, the Big Five Questionnaire for children, the Emotional Intelligence Index and the Empathy-Teen Conflict Survey.ResultsData showed that openness, conscientiousness, and agreeableness were inversely related to bullying, and that the causal chain of TEI-empathy negatively and completely mediated the relationship between emotional instability and bullying and negatively and partially mediated the relationship between openness and bullying.ConclusionsThese results suggest that TEI and empathy mediate the relationship between personality traits and bullying, reducing the risk of being involved in bullying perpetration.     

Race, brain size, and intelligence: a reply to Cernovsky

Cernovsky's 1990 critique of my work on the relation between brain size and IQ inadequately presents my position. I did not address the issue of sex differences in brain size nor did I conclude that "women are less intelligent than men" (p. 337). In the autopsy study cited by Cernovsky, it was concluded that, when body size is controlled, the male-female difference in brain size is removed but the black-white difference in brain size remains. Cernovsky also ignores much additional data, including that Mongoloid populations have larger and heavier brains than Caucasoids. Here, I review evidence on the relation between (a) brain size and race and (b) brain size and intelligence. Data are also tabulated for personality, speed of maturation, and sexuality, on all of which the Caucasoid average consistently falls between those of Mongoloids and Negroids. This ordering may be explained by a gene-based evolutionary theory of r/K reproductive strategies in which Mongoloids are more K-selected than Caucasoids and Caucasoids more than Negroids.     

Race and the workforce: occupational status,aspirations, and stereotyping among African American children

This study examined whether African American children's perceptions of occupational status and their own vocational interests are affected by racial segregation of the workforce. Children (N = 92) rated familiar occupations with respect to status, desirability, and stereotyping. Children also rated novel jobs that had been depicted with African Americans, European Americans, or both African and European Americans. As predicted, for familiar jobs, children's judgments were linked to their knowledge of racial segregation of these jobs. In addition, novel occupations that had been depicted with African Americans were judged as lower in status than the identical occupations that had been depicted with European Americans, demonstrating a causal influence of workers' race on children's judgments. Children's age and socioeconomic background moderated their occupational judgments.     

Perceived emotional intelligence and self-efficacy among Chinese secondary school teachers in Hong Kong

One hundred and fifty-eight secondary school teachers were assessed on their perceived emotional intelligence (Schutte et al., 1998) and general self-efficacy and self-efficacy toward helping others ( Schwarzer, 1993). An item factor analysis yielded four dimensions of perceived emotional intelligence, leading to the construction of four corresponding empirical scales. Teachers scored most highly on positive utilisation and emotional appraisal, followed by empathic sensitivity and positive regulation. Using the four components of perceived emotional intelligence as predictors of self-efficacy beliefs, positive regulation emerged as the significant predictor in predicting general self-efficacy whereas empathic sensitivity emerged as the significant predictor in predicting self-efficacy toward helping others. Implications of the findings for exploring the relationships between various components of perceived emotional intelligence and various specific self-efficacy beliefs for different groups of teachers and the need for further studies using longitudinal data are discussed.     

Relationships among attributes, physical fitness, and self-concept development of elementary school children.

The purpose of the investigation was to examine the relationships among children's selected attributes, health-related physical fitness; and self-concept development. Subjects were 97 elementary school children in Grades 1 through 6. Correlations were examined for significance and effect size among the attributes of age, weight, body mass index, four scores from the Health Related Physical Fitness Test, and the total score from the Martinek-Zaichkowsky Self-concept Scale for Children. A max R2 forward stepwise multiple regression analysis was performed to assess which attribute and physical fitness variables were the best predictors of self-concept scores. Analysis indicated that the one-variable model of weight was the best predictor of self-concept.     

Group aggression among school children in three schools

"Mobbing", i.e. school children repeatedly ganging up on the same victims, was studied among 434 12–16 years old children in three schools in Finland. A group of bullies and a group of victims were selected on basis of peer ratings. 13.7% of the boys and 5.4% of the girls were involved in mobbing behaviour. The children's personality variables were studied with questionnaires. The victims had low self-esteem, were subjectively maladjusted, and experienced their peer relations negatively. The victims were physically weaker than well-adjusted children, and obesity and handicaps were more common among them. The bullies were physically strong, and handicaps were also among them more frequent than among well-adjusted children. The bullies held positive attitudes towards aggression, experienced their peer relations negatively, and held negative attitudes towards teachers and peers. They were unpopular among their peers, though not so unpopular as the victims.     

Direct and relational bullying among primary school children and academic achievement

The association between bullying behaviour and academic achievement was investigated in 1016 children from primary schools (6-7-year-olds/year 2: 480; 8-9-year-olds/year 4: 536). Children were individually interviewed about their bullying experiences using a standard interview. Key Stage I National Curriculum results (assessed at the end of year 2) were collected from class teachers, and parents completed a behaviour and health questionnaire. Results revealed no relationship between direct bullying behaviour and decrements in academic achievement. Conversely, higher academic achievement at year 2 predicted bullying others relationally (e.g. social exclusion at year 4). Relational victimisation, Special Educational Needs (SEN), being a pupil from a rural school or small classes and low socioeconomic status (SES) predicted low academic achievement for year 2 children. Findings discount the theory that underachievement and frustration at school leads to direct, physical bullying behaviour.     

Relevance of education and intelligence for the political development of nations: Democracy, rule of law and political liberty

Political theory has described a positive linkage between education, cognitive ability and democracy. This assumption is confirmed by positive correlations between education, cognitive ability, and positively valued political conditions (N = 183 − 130). Longitudinal studies at the country level (N = 94 − 16) allow the analysis of causal relationships. It is shown that in the second half of the 20th century, education and intelligence had a strong positive impact on democracy, rule of law and political liberty independent from wealth (GDP) and chosen country sample. One possible mediator of these relationships is the attainment of higher stages of moral judgment fostered by cognitive ability, which is necessary for the function of democratic rules in society. The other mediators for citizens as well as for leaders could be the increased competence and willingness to process and seek information necessary for political decisions due to greater cognitive ability. There are also weaker and less stable reverse effects of the rule of law and political freedom on cognitive ability.     

Mental flexibility as resiliency factor among children exposed to political violence

The research focused on mental flexibility versus rigidity in explaining psychological adjustment in the violent conditions of Intifada, and in more peaceful times 3 years later, among 86 Palestinian children. A picture test based on Brunswik (1949) was applied to measure flexible‐rigid cognitive style, and neuroticism, self‐esteem, emotional disorders, and PTSD were used as outcome variables. Results revealed a moderating role of mental flexibility by showing that children were protected from negative long‐term consequences of traumatic events if their perception indicated mental flexibility. However, in the midst of violence mental flexibility was not associated with good psychological adjustment. Mental flexibility was, in turn, determined by environmental and cognitive factors: The more intelligent and the less exposed to traumatic events children were, the higher mental flexibility they showed.
