Children's sleep and cognitive functioning: race and socioeconomic status as moderators of effects

Race and socioeconomic status (SES) moderated the link between children's sleep and cognitive functioning. One hundred and sixty-six 8- to 9-year-old African and European American children varying in SES participated. Sleep measures were actigraphy, sleep diaries, and self-report; cognitive measures were from the Woodcock-Johnson III and reaction time tasks. Children had similar performance when sleep was more optimal, but after controlling for SES, African American children had lower performance with sleep disruptions. Children from lower and higher SES had similar performance with better sleep quality and less variability in sleep schedules, but when sleep was more disrupted, higher SES children had better performance. Examination of environmental variables associated with race and SES that may underlie these effects may lead to directions for interventions to improve cognitive performance.     

Sharing information books with kindergartners: The role of parents’ extra-textual talk and socioeconomic status

The purpose of the study was to explore how features of parent–child extra-textual talk during information book-sharing might vary across different socioeconomic backgrounds, and to determine if certain interactional patterns might mediate their effects on children's receptive and expressive vocabulary development. Sixty parents and their 5-year-old children were audio-recorded reading an unfamiliar information book in their home. Holistic coding on six parent and two child engagement scales, examining low to high cognitive demanding talk was conducted. Results indicated that lexical richness and contingent responsiveness positively predicted receptive and expressive vocabulary. Further, contingent responsiveness appeared to mediate the influence of socioeconomic status on children's receptive and expressive vocabulary, suggesting that positive environmental contexts and supportive parent–child interactions can have a powerful influence on children's development.     

The development of audiovisual speech perception in Mandarin-speaking children: Evidence from the McGurk paradigm

The developmental trajectory of audiovisual speech perception in Mandarin-speaking children remains understudied. This cross-sectional study in Mandarin-speaking 3- to 4-year-old, 5- to 6-year-old, 7- to 8-year-old children, and adults from Xiamen, China (n = 87, 44 males) investigated this issue using the McGurk paradigm with three levels of auditory noise. For the identification of congruent stimuli, 3- to 4-year-olds underperformed older groups whose performances were comparable. For the perception of the incongruent stimuli, a developmental shift was observed as 3- to 4-year-olds made significantly more audio-dominant but fewer audiovisual-integrated responses to incongruent stimuli than older groups. With increasing auditory noise, the difference between children and adults widened in identifying congruent stimuli but narrowed in perceiving incongruent ones. The findings regarding noise effects agree with the statistically optimal hypothesis.     

A Longitudinal Study of the Relationship of High School Foreign Language and Mathematics Study to Freshman Grades

Abstract

The purpose of this study was to examine the prevalence and effect of answer-changing on objective test performance. 5s were 77 college students of both sexes. All types of response changes were recorded and analysed by sex and by caliber of student. Results showed that when a response was changed there was a three-to-one chance that the new response would Improve rather than lower the final score. Females were more Inclined to make changes than were males, and their overall test performance was superior to that of males. The brightest 5s of both sexes made the greatest mean number of answer changes. It was concluded that the fear frequently expressed by students that answer changes will reduce test performance was unfounded In this instance.     

Assessing early arithmetic abilities: Effects of verbal and nonverbal response types on the calculation performance of middle-and low-income children

In two studies, we compared young children's performance on three variations of a nonverbally presented calculation task. The experimental tasks used the same nonverbal mode of presentation but were varied according to response type: (1) putting out disks (nonverbal production); (2) choosing the correct number of disks from a multiple-choice array (nonverbal recognition); and (3) giving a number word (verbal production). The verbal production task required children to map numerosities onto the conventional number system while the nonverbal production and nonverbal recognition tasks did not. Study 1 showed that the performance of 3-, 4- and 5-year-old middle-income children (N = 72) did not vary with the type of response required. Children's answers to nonverbally presented addition and subtraction problems were available in both verbal and nonverbal forms. In contrast. Study 2 showed that low-income children (3- and 4-year-olds; N = 48) performed significantly better on both nonverbal response type tasks than on the verbal response type task. Analysis of individual data indicated that a number of the low-income children were successful on the completely nonverbal calculation tasks, even though they had difficulty with verbal counting (i.e., set enumeration and cardinality). The findings suggest that the ability to calculate does not depend on mastery of conventional symbols of arithmetic.     

Contextual influences on children's mental health and school performance: the moderating effects of family immigrant status

Data from a nationally representative sample of 13,470 children aged 4-11 years were used to study contextual influences on children's mental health and school performance, the moderating effects of family immigrant status and underlying family processes that might explain these relationships. Despite greater socioeconomic disadvantage, children living in recent immigrant families had lower levels of emotional-behavioral problems and higher levels of school performance. Living in a neighborhood characterized with higher concentration of immigrants was associated with lower levels of emotional-behavioral problems among children living in immigrant families; the reverse was true for children living in nonimmigrant families. These differences are partially explained by family process variables. The implications of these findings for future research and policy are discussed.     

Nonverbal and Verbal Performance on a Number Conservation Problem and a Proposal about the Determinants of Nonconservation

This study compared the ease of verbal and nonverbal versions of a number conservation problem for 4and S‐year‐old children. The nonverbal task employed a ‘train‐transfer’ procedure in which children were first trained to a criterial level to make one response to stimulus pairs that contained two rows of the same number in one‐to‐one correspondence and a different response to stimulus pairs in which one of the rows was of greater or of lesser number than the other. Conservation performance was maintaining the learned response to the identical pair after one of its rows had been deformed. Taking both ages together the nonverbal task was the easier. However, children's justifications showed that verbal processes may have been responsible for both correct and incorrect performance in many cases. The data are interpreted as supporting the hypothesis that children interpret conservation terms perceptually when used by others in certain contexts in spite of what they know about the underlying fact of conservation.     

The Home Literacy Environment as a Predictor of the Early Literacy Development of Children at Family-Risk of Dyslexia

The home literacy environment (HLE) predicts language and reading development in typically developing children; relatively little is known about its association with literacy development in children at family-risk of dyslexia. We assessed the HLE at age 4 years, precursor literacy skills at age 5, and literacy outcomes at age 6, in a sample of children at family-risk of dyslexia (n = 116) and children with no known risk (n = 72). Developmental relationships between the HLE and literacy were comparable between the groups; an additional effect of storybook exposure on phoneme awareness was observed in the family-risk group only. The effects of socioeconomic status on literacy were partially mediated by variations in the HLE; in turn, effects of the HLE on literacy were mediated by precursor skills (oral language, phoneme awareness, and emergent decoding) in both groups. Findings are discussed in terms of possible gene–environment correlation mechanisms underpinning atypical literacy development.     

The Effects of Learner Characteristics on Performance in Programed Text and Conventional Text Formats

Abstract

The authors investigated the development of the ability of 4-, 5-, 6-, and 7-year-old bilingual children to perform a complex perceptual-motor task when they were given only Spanish or English verbal instructions. Results indicated that children perform better when given Spanish instruction. This was especially true of the 5-year-olds. Results also indicated that performance under both languages increased with age, and that a stable system of perceptual-motor connections was established by verbal instruction under the Spanish treatment at age 6 and under the English treatment at age 7.     

Children's hypothetical reasoning about complex and dynamic systems

Children's hypothetical reasoning about a complex and dynamic causal system was investigated. Predominantly White, middle-class 5- to 7-year-old children from the Greater Toronto Area learned about novel food chains and were asked to consider the effects of removing one species on the others. In Study 1 (N = 72; 36 females, 36 males; 2018), 7-year-olds answered questions about both direct and indirect effects with a high degree of accuracy, whereas 5-year-olds performed at chance. Six-year-olds showed intermediate performance. Using food chains with clearer constraints, Study 2 (N = 72; 35 females, 37 males; 2020–2021) replicated these findings. These results indicate that the ability to think about hypothetical changes to dynamic causal systems develops between 5 and 7 years. Implications for science education are discussed.     

Korean preschoolers' advanced inhibitory control and its relation to other executive skills and mental state understanding

This study assessed executive function and mental state understanding in Korean preschoolers. In Experiment 1, forty 3.5- and 4-year-old Koreans showed ceiling performance on inhibition and switching measures, although their performance on working memory and false belief was comparable to that of Western children. Experiment 2 revealed a similar advantage in a sample of seventy-six 3- and 4-year-old Koreans compared with sixty-four age-matched British children. Korean children younger than 3.5 years of age showed ceiling effects on some inhibition measures despite more stringent protocols and the link between executive function and mental state understanding was not as strong as in the British sample. The results raise key questions about the nature and development of the executive system and its relation to social understanding.     

Effect of number of response options on the psychometric properties of Likert-type scales used with children

Although Likert-type rating scales are used in a great number of early childhood studies, knowledge of how the number of response options affects the psychometric properties of scales used with children is limited. The purpose of this study is to contribute to this knowledge. Data were collected from second grade students and third grade students. Accordingly, 1,092 second- and third-graders completed a 2-point, 3-point, and 4-point version of the School Attachment Scale for Children and Adolescents. Participants came from 11 schools, different in terms of socioeconomic status. The children received the versions approximately three weeks apart. Results revealed that as the number of response options increased, the means tended to decrease and the distribution to be normal. For the 2-point version, most items were below the cut-off point in terms of discrimination indexes. Compared to the 2-point version, there was a significant increase in discrimination indexes for the 3- and 4-point versions, and the items’ discrimination indexes were high. It was concluded that the reliability coefficient increased with an increasing number of response options for all subdimensions of the scale. When the validity estimations of the three subdimensions were examined for the three versions of the scale, it was found that the 3- and 4-point versions were appropriate for the validity and that the validity of the 2-point version was weak. It was observed that using 2-point Likert-type scales with children negatively affected the psychometric properties and that these properties improved with an increased number of response options.     

Childhood correlates of adult ego development

The present study examined family socioeconomic indicators, parent child-rearing variables, and childhood and adolescent behaviors, which were hypothesized to predict adult ego development. The subjects were 206 females and 192 males, ages 30-31, who began participating in a longitudinal study at age 8. At that time, interviews with their parents yielded data on family background variables and child-rearing practices. Peer-nominations and other testing procedures with the children yielded data on the children's cognitive and behavioral styles at ages 8 and 19. At age 30, the subjects completed the Loevinger Sentence Completion Test of Ego Development. Results confirmed the hypotheses that child-rearing styles characterized by acceptance, a nonauthoritarian approach to punishment, and identification of the child with the parent related to higher levels of adult ego development 22 years later. These relations obtained more strongly for females than for males. In addition, childhood and adolescent indicators of impulse control and cognitive development (nonaggression, prosocial behavior, and intelligence) were associated with higher levels of adult ego development. Finally, hierarchical multiple regression analyses indicated that the development of aggression was linked to adult ego level attainment in males, while the development of prosocial behavior was related to adult ego development in females.     

A Controlled Evaluation of a High School Biomedical Pipeline Program: Design and Methods

Given limited funding for school-based science education, non-school-based programs have been developed at colleges and universities to increase the number of students entering science- and health-related careers and address critical workforce needs. However, few evaluations of such programs have been conducted. We report the design and methods of a controlled trial to evaluate the Stanford Medical Youth Science Program’s Summer Residential Program (SRP), a 25-year-old university-based biomedical pipeline program. This 5-year matched cohort study uses an annual survey to assess educational and career outcomes among four cohorts of students who participate in the SRP and a matched comparison group of applicants who were not chosen to participate in the SRP. Matching on sociodemographic and academic background allows control for potential confounding. This design enables the testing of whether the SRP has an independent effect on educational- and career-related outcomes above and beyond the effects of other factors such as gender, ethnicity, socioeconomic background, and pre-intervention academic preparation. The results will help determine which curriculum components contribute most to successful outcomes and which students benefit most. After 4 years of follow-up, the results demonstrate high response rates from SRP participants and the comparison group with completion rates near 90 %, similar response rates by gender and ethnicity, and little attrition with each additional year of follow-up. This design and methods can potentially be replicated to evaluate and improve other biomedical pipeline programs, which are increasingly important for equipping more students for science- and health-related careers.     

Planar asymmetry tips the phonological playground and environment raises the bar

Reading readiness varies as a function of family and environmental variables. This study of 11-year-old children (N = 39) was designed to determine if there was an additional or interactive contribution of brain structure. Evidence is presented that both environmental and biological variables predict phonological development. Temporal lobe (planar) asymmetry, hand preference, family history of reading disability, and SES explained over half of the variance in phonological and verbal performance. The results demonstrate a linear association between cerebral organization and phonological skill within socioeconomic groups. These data provide concrete evidence to support the commonly held assumption that both environmental and biological factors are independent determinants of a child's ability to process linguistic information.     

Performance of Montessori and traditionally schooled nursery children on tasks of seriation, classification, and conservation

It was hypothesized that the Montessori curriculum accelerates the acquisition of a number of concrete operational skills. To test this, eighty 4-year-old children were given three Piagetian problems—seriation, classification, and conservation. Half of the subjects were from Montessori schools, and the other half were from more traditional nursery settings. Within each type of school, half of the children were first year and the other half were second year enrollees. Results showed that significantly more Montessori than traditional children seriated and classified objects like concrete thinkers but that there were no differences on the conservation problem. Year of enrollment did not influence performance on any of the tasks. It was concluded that the hypothesis was confirmed and that the failure to find acceleration of conservation performance was due to its advanced nature relative to the other problems and/or the tangential manner in which Montessori exercises deal with the critical concepts that underly it.     

Associations between urbanization and the home language environment: Evidence from a LENA study in rural and peri-urban China

In low- and middle-income countries, urbanization has spurred the expansion of peri-urban communities, or urban communities of formerly rural residents with low socioeconomic status. The growth of these communities offers researchers an opportunity to measure the associations between the level of urbanization and the home language environment (HLE) among otherwise similar populations. Data were collected in 2019 using Language Environment Analysis observational assessment technology from 158 peri-urban and rural households with Han Chinese children (92 males, 66 females) aged 18–24 months in China. Peri-urban children scored lower than rural children in measures of the HLE and language development. In both samples, child age, gender, maternal employment, and sibling number were positively correlated with the HLE, which was in turn correlated with language development.     

New Destinations,New Trajectories? The Educational Progress of Hispanic Youth in North Carolina

Since 1990, Latin American immigrants to the United States have dispersed beyond traditional gateway regions to a number of "new destinations." Both theory and past empirical evidence provide mixed guidance as to whether the children of these immigrants are adversely affected by residing in a nontraditional destination. This study uses administrative public school data to study over 2,800 8- to 18-year-old Hispanic youth in one new destination, North Carolina. Conditional on third-grade socioeconomic indicators, Hispanic youth who arrive by age 9 and remain enrolled in North Carolina public schools close achievement gaps with socioeconomically similar White students by sixth grade and exhibit significantly lower high school dropout rates. Their performance resembles that of first-generation youth in more established immigration gateways.     

Deficits in bannatyne's sequencing ability on the WISC and WISC-R for mildly retarded and borderline functioning children over time

The WISC and WISC-R protocols of 94 special education students (51 white males, 5 black males, 30 white females, and 8 black females) who tested in the mildly retarded and borderline range of abilities (IQs of 50–78) were examined. Their test performance was then followed longitudinally for two additional WISC and WISC-R assessments. Mean age of subjects was 8 years at Test 1, 10.75 years at Test 2, and 14.9 years at Test 3. As predicted, subjects had lower IQ equivalent scores on Bannatyne's Sequencing Ability category than their IQ equivalent scores on the Verbal Comprehension or Perceptual Organization factors of the WISC and WISC-R for all three testings. Results were interpreted as supporting the notion that mildly retarded children and learning disabled children have qualitatively similar learning patterns.
