Gender and its contribution to the prediction of cognitive abilities at 5 years

Gender-related differences in the prediction of five year-olds' cognitive abilities from measures of distal environment, proximal environment and infant test scores were examined in a random sample of 93 boys and 90 girls. Distal environmental data included maternal IQ, maternal and paternal education. Proximal environmental data included two variables derived from the Home Screening Questionnaire: the Home Questions and the Toy Checklist. The Bayley MDI was administered at age 13 months, whereas WPPSI-R was used as cognitive outcome measure at age 5 years. The relationship between paternal education and child IQ, and between proximal environmental variables and child IQ was significantly stronger for boys than for girls. The associations between proximal environment and IQ in boys, were accounted for by the distal environmental variables. Bayley MDI correlated significantly higher with girls' IQ compared to boys' IQ. Findings are discussed in terms of parental gender-differentiated socialization processes.     

Association between maternal sensitivity and externalizing behavior from preschool to preadolescence

Using data from the longitudinal NICHD Study of Early Child Care and Youth Development (N = 1364), this study examined the association between mothers' sensitivity and children's externalizing behavior from preschool to preadolescence. Externalizing behavior declined on average across this period with a slowing of this decline around middle childhood. Maternal sensitivity remained relatively stable on average, and there was significant variation across mothers. A decrease in maternal sensitivity from ages 3 to 11 was related to an increase in externalizing behavior from ages 4 to 12. A model-based test of the direction of the effect suggested that the association between changes in maternal sensitivity and externalizing behavior from ages 4 to 11 was driven by child effects on mothers and not vice-versa. Between late preschool age and preadolescence, the behavior problems of children appear to strongly influence the sensitive support of mothers. Practical implications were discussed in light of these findings.     

Investigating the relationship between social behaviors and phonological awareness in preschool children

Purpose

This study examined the longitudinal effects of social behaviors in predicting phonological awareness outcomes in 4-year-old children.

Method

One hundred two children (52 boys, 50 girls) were recruited from 11 schools serving low-income neighborhoods in a large metropolitan city and were assessed at the beginning and end of the preschool year. All children received assessments of their phonological awareness skills, expressive vocabulary, non-verbal IQ, and teachers completed behavioral ratings at pretest. At the end of the academic year, children participated in tests of phonological awareness using standardized assessments.

Results

The results of a multiple regression analysis indicated that being excluded by peers contributed up to 3% of the variance in negatively predicting phonological awareness outcomes after controlling for initial phonological awareness skills, expressive vocabulary, and cognition which is a small effect size.

Conclusion

Early peer exclusion can impact negatively on the acquisition of phonological awareness skills in 4-year-old children in preschool. The results of this study suggest that a child's overall behavioral competence and how they are treated by the peer group may play an important role in their ease of academic skill attainment. Given the link between peer exclusion and difficulties with phonological awareness outcomes, additional professional development programs that provide teachers with strategies to create inclusive classrooms may be warranted in preventing against the emergence of maladaptive behaviors at first entry into formal schooling.     

The relationship between cognitive dissonance and helping behavior

An experiment was conducted to study the relationship between cognitive dissonance and helping behavior. A counterattitudinal procedure was employed to arouse dissonance. For half of the participants, an experimental confederate entered the room and elicited an opportunity for them to offer help. In this situation, fewer subjects in the dissonance condition offered help than subjects in the no‐dissonance condition. The least helping occurred among dissonance subjects with the highest level of commitment to the counterattitudinal task. Those with a medium level of commitment offered significantly more help. Despite the fact that results in line with Festinger's cognitive dissonance theory (subjects' attitudinal change) were obtained in the no‐helping situation, in helping situations, dissonance subjects who offered help presented significantly less attitude change than those who did not offer it. This was considered to be a result of helpfulness reducing dissonance arousal.     

The association between maternal strategies and preschoolers' memory for location of objects

Using a Vygotskian theoretical framework and a social interaction design, we observed 30 middle-class North American mother–child dyads engaged in a location memory activity. The central aim of this investigation was to assess maternal and preschool strategy use employed during a memory for location task, and to determine which strategies are associated with preschooler accuracy of memory for location of objects. Results suggest that mothers are more apt to utilize labelling, encouragement, and guidance as opposed to location-specific assistance to their child during the task, and children are more apt to link the memory information to their real-life experiences, request help for assistance, and utilize self-regulatory speech. Implications of the research, suggestions for future research, and expansions of theoretical perspectives on the role of social interaction on preschool location memory performance, and educational implications are discussed.     

The biasing effect of personality on self-estimates of cognitive abilities in males and females

In addition to exploring the relationship between psychometric and self-estimated measures of Crystallized Knowledge (Gc) and Visual Processing (Gv), this study investigated whether personality significantly moderated these relationships, thereby influencing the accuracy of the self-estimates. Adult participants (N = 165) completed the Big Five Inventory and self-estimated their levels of Gc and Gv. They were subsequently administered the Multidimensional Aptitude Battery II, a group test of cognitive ability. Significant and positive relationships between psychometric Gc and Gv and their respective self-estimates were found. Additionally, investigation of the moderating effects of personality for each gender separately using standard multiple regressions found that females high in Extraversion and males low in Conscientiousness were more prone to overestimating their Gv ability, while males high in Openness provided more accurate estimates of their Gv than those low in Openness. Elucidating the personality traits that distort self-perceptions of intellectual functioning has significant implications for the identification of individuals at risk of harboring inaccurate expectations, leading to the potential for interventions aimed at ameliorating associated deleterious consequences.     

Early motor development and cognitive abilities among Mexican preschoolers

Psychomotricity plays a very important role in children’s development, especially for learning involving reading–writing and mathematical calculations. Evaluate motor development in children 3 years old and its relationship with their cognitive abilities at the age of 5 years. Based on a cohort study, we analyzed the information about motor performance evaluated at 3 years old by Peabody Motor Scale and cognitive abilities at 5 years old. The association was estimated using linear regression models adjusted by mother’s intelligence quotient, sex, Bayley mental development index at 18 months, and quality of the environment at home (HOME scale). 148 children whose motor performance was determined at age 3 and was evaluated later at age 5 to determine their cognitive abilities. Cognitive abilities (verbal, quantitative, and memory) measured by McCarthy Scales. Significant positive associations were observed between stationary balance at age 3 with verbal abilities (β = 0.67, p = .04) and memory (β = 0.81, p = .02) at 5 years. Grasping and visual-motor integration were significant and positively associated with quantitative abilities (β = 0.74, p = .005; β = 0.61, p = .01) and memory (β = 2.11, p = .001; β = 1.74, p = .004). The results suggest that early motor performance contributes to the establishment of cognitive abilities at 5 years. Evaluation and early motor stimulation before the child is faced with formal learning likely helps to create neuronal networks that facilitate the acquisition of academic knowledge.

婴儿期外显问题行为的发生与表现及成因分析

外显问题行为是指一组表现在外的、反映了儿童对外部环境消极反应的行为。研究表明婴儿最早于8个月时便已出现外显问题行为,且婴儿期这类行为主要表现为愤怒/发脾气、不顺从/反抗、攻击、破坏性、过度活跃、注意力不集中等,其成因可从早期经验因素、遗传与环境的交互作用等方面解释。此外,外显问题行为的干预研究可从差别易感性理论入手,从而为特定气质类型以及携带可塑性基因的婴儿提高了外显问题行为的干预效果。本文在梳理上述研究的基础上,对该领域研究的局限性进行了小结并对未来研究的方向进行了展望。     

Cognitive abilities of street children: Low-SES Bolivian boys with and without experience of living in the street

Objectives: This study compared results on cognitive tests measuring nonverbal visualization and reasoning, executive functions, and creativity between 36 boys with experience of living in the street and 31 housed yet socioeconomically equivalent boys, in Bolivia.

Results: The street children scored significantly higher on the creativity measure, which is discussed in relation to contextual relevance. No significant differences were found on the other cognitive tests. Time elapsed after living in the street and drug use were strongly associated with cognition, while age was not. Both groups scored below average compared to Western norms. The results are discussed in terms of the cultural relevance of the tests and the impact of socioeconomic status, stress, and stimulation on cognition.     

The effect of labeling on preschool children's performance in the Dimensional Change Card Sort Task

Previous research suggests that experimenter-induced labeling of test cards improves preschoolers’ performance on the Dimensional Change Card Sort Task (DCCS), a measure of flexible rule use. Three experiments attempted to further clarify how labeling aids performance on the DCCS. Experiment 1 examined the nature of the labeling effect but failed to show any benefit of labeling on children's performance. Experiment 2 failed to replicate the labeling effect reported by [Kirkham, N. Z., Cruess, L. M., & Diamond, A. (2003). Helping children apply their knowledge to their behavior on a dimension-switching task. Developmental Science, 6, 449–467] despite closely matching their procedures. Experiment 3 demonstrated that labeling procedures designed to counteract the suppression of the post-switch sorting dimension also failed to improve performance on the DCCS. We discuss the implications of these findings for identifying factors that positively affect preschoolers’ cognitive flexibility.     

The relationship between the cognitive style and play behaviors of 3-to-5-year-old children

Children (N=1276) ages 3 to 5 were tested for their cognitive style (field dependence/independence) and their play behaviors were observed and recorded. A repeated measures multivariate analysis of variance (MANOVA) for the children's play behaviors was found to be significant by the Wilks' lambda criterion, indicating that FD and FI individuals played differently. That is, FD children engaged more in play than did FI ones. Three significant interactions were found for cognitive style and play behaviors: (a) cognitive style and play behaviors, (b) age, cognitive style, and play behaviors, and (c) age, sex, cognitive style, and play behaviors. Four- and 5-year-old FD children usually had the most play behaviors except for the leadership abilities where 3-year-old FI children had the highest scores in dramatic play. In contrast, 3- and 4-year-old FI children had the least play behaviors except for frequency of play where 5-year-old FI children had the lowest scores in all of the play areas. The children's play behaviors were also influenced by their cognitive style, sex and age.     

Grammatical gender and inferences about biological properties in german-speaking children

In German, nouns are assigned to one of the three gender classes. For most animal names, however, the assignment is independent of the referent's biological sex. We examined whether German-speaking children understand this independence of grammar from semantics or whether they assume that grammatical gender is mapped onto biological sex when drawing inferences about sex-specific biological properties of animals. Two cross-linguistic studies comparing German-speaking and Japanese-speaking preschoolers were conducted. The results suggest that German-speaking children utilize grammatical gender as a cue for inferences about sex-specific properties of animals. Further, we found that Japanese- and German-speaking children recruit different resources when drawing inferences about sex-specific properties: Whereas Japanese children paralleled their pattern of inference about properties common to all animals, German children relied on the grammatical gender class of the animal. Implications of these findings for studying the relation between language and thought are discussed.     

Social information processing in preschool children: Relations to sociodemographic risk and problem behavior

Using a multicomponent, process-oriented approach, the links between social information processing during the preschool years and (a) sociodemographic risk and (b) behavior problems in preschool were examined in a community sample of 196 children. Findings provided support for our initial hypotheses that aspects of social information processing in preschool are related to both sociodemographic risk and behavior problems in preschool. Response evaluation and in particular the positive evaluation of an aggressive response were related to both sociodemographic risk and children’s aggressive behavior and partially mediated the links between sociodemographic risk and aggressive behavior in preschool.     

The relationship between age and frequency of disfluency in preschool children

The frequencies of nine types of disfluency, including silent pauses, were studied in 60 nonstuttering males, 3.5 and 5 yr-of-age. The younger children evidenced significantly higher rates of part word, word, and phrase repetitions, incomplete phrases, and disrhythmic phonations. The older children demonstrated significantly more grammatical pauses. The two groups did not differ in the frequency of interjections, ungrammatical pauses, and revisions. The most powerful discriminating category between the two age groups was phrase repetition. The results are compared with findings from other recent investigations of disfluency in nonstuttering preschool males. Possible explanations for the discrepancies among the various investigations and for the high degree of variability in disfluency reported in the literature are proposed. The results of this investigation suggest that nonstuttering children begin to show more adult-like disfluency patterns toward the later preschool years.     

Grammatical language impairment and the specificity of cognitive domains: relations between auditory and language abilities

Grammatical-specific language impairment (G-SLI) in children, arguably, provides evidence for the existence of a specialised grammatical sub-system in the brain, necessary for normal language development. Some researchers challenge this, claiming that domain-general, low-level auditory deficits, particular to rapid processing, cause phonological deficits and thereby SLI. We investigate this possibility by testing the auditory discrimination abilities of G-SLI children for speech and non-speech sounds, at varying presentation rates, and controlling for the effects of age and language on performance. For non-speech formant transitions, 69% of the G-SLI children showed normal auditory processing, whereas for the same acoustic information in speech, only 31% did so. For rapidly presented tones, 46% of the G-SLI children performed normally. Auditory performance with speech and non-speech sounds differentiated the G-SLI children from their age-matched controls, whereas speed of processing did not. The G-SLI children evinced no relationship between their auditory and phonological/grammatical abilities. We found no consistent evidence that a deficit in processing rapid acoustic information causes or maintains G-SLI. The findings, from at least those G-SLI children who do not exhibit any auditory deficits, provide further evidence supporting the existence of a primary domain-specific deficit underlying G-SLI.     

The relations between maternal behaviors and urban preschool children's internal working models of attachment security

Interviewed 93 African-American, low-income women who had become pregnant as teenagers and their preschool-aged children in their homes. Mothers answered questions regarding their everyday stresses and feelings of depression. Children were assessed for receptive vocabulary ability, then video-taped completing five stories thematically related to attachment experiences with mother and rated on their security of attachment. Mothers and children were also videotaped playing together, and mothers were assessed on their sensitivity to their children's cues. After controlling for children's age and receptive vocabulary ability, mothers' sensitivity significantly predicted children's level of attachment security. The positive association between maternal sensitivity and children's security of attachment, and the strengths and weaknesses of administering the Attachment Story-Completion Task in the home with this population, are discussed. Implications for assessing attachment in the home are considered.
