Risk for sleep-disordered breathing and home and classroom behavior in Hispanic preschoolers.

Pediatric sleep-disordered breathing (SDB) is known to negatively impact home and classroom behavior. Preschool-age Hispanic children from Spanish-speaking households are at elevated risk for poor school readiness. The authors used a multi-informant approach to assess home and preschool behavior among Hispanic children at risk for SDB (n = 67). Higher parent-reported SDB risk and elevated snoring were associated with parent- and teacher-reported problem behaviors and poorer teacher-reported classroom executive function among boys; elevated snoring was associated with internalizing behaviors among girls. Elevated snoring may be associated with problems related to impaired inhibitory self-control, suggesting the need for early intervention in order to improve school readiness among these a priori defined at-risk Hispanic children.

Risk for sleep-disordered breathing and executive function in preschoolers.

BACKGROUND: Pediatric sleep-disordered breathing is known to negatively impact cognitive development. While a theoretical basis has been proposed for the developmental effect of pediatric sleep-disordered breathing on executive function specifically, this had not been directly examined among preschool-age children. This population may be particularly vulnerable if school-readiness is compromised. The purpose of the current study was to use a multi-dimensional approach to assessing executive function among preschool-age children at risk for sleep-disordered breathing. METHODS: Thirty-nine preschool children were administered executive function tasks assessing the dimensions of inhibition, working memory, and planning as part of a larger study. A parent or guardian completed a validated questionnaire concerning the child's snoring and other behaviors indicating risk for sleep-disordered breathing. RESULTS: After controlling for age in a series of regressions, higher parent-reported risk for sleep-disordered breathing was associated with substantially lower performance on each executive function dimension. In comparing the group means of children at high and low risk for sleep-disordered breathing, the single snoring frequency item also showed that children who snored frequently or almost always had lower performance on each executive function dimension. CONCLUSIONS: The results suggest that sleep-disordered breathing may be associated with impaired executive function in preschoolers, with its strongest impact on the inhibition dimension, further emphasizing the importance of early intervention for sleep-disordered breathing in this early age group.

Large state-level fluctuations in mental retardation classifications related to introduction of renormed intelligence test.

Oppositely valenced forces may be at work to influence rates of placement of children into mental retardation programs. On one hand, educational policies regarding intellectual disability and concerns about overrepresentation of minorities in special education may contribute to lower placement rates; on the other hand, more difficult intelligence test norms may be a countervailing force, increasing placement rates. An analysis of longitudinal data on state and national level placement rates reveals that a lengthy and steep 12-year decline in students receiving mental retardation services reversed shortly after the introduction of the WISC-III in 1991. This phenomenon has relevance for death-penalty cases, because this historical pattern may affect the ability to establish whether an adult meets the developmental period onset criterion for mental retardation.

Theory of mind, inhibitory control, and preschool-age children's suggestibility in different interviewing contexts.

The current study examined the relations among 3- to 5-year-olds' theory of mind, inhibitory control, and three measures of suggestibility: yielding to suggestive questions (yield), shifting answers in response to negative feedback (shift), and accuracy in response to misleading questions during a pressured interview about a live event. Theory of mind aided in the prediction of suggestibility about the live event, and inhibitory control was a moderator variable affecting the consistency of children's sensitivity to social pressure across situations. The findings indicate that theory of mind and inhibitory control predict children's suggestibility about a live event above and beyond yield, shift, and age and that the construct validity of shift may improve as children's inhibitory control develops.

Suggestibility, social support, and memory for a novel experience in young children.

This study examined 5- and 6-year-olds' suggestibility and interviewer demeanor as joint predictors of their memory for a novel experience. Session 1 consisted of children taking part in a novel laboratory event. Session 2 took place after approximately a 1-week delay and consisted of children completing both a memory test concerning what happened during the prior event and the Video Suggestibility Scale for Children (VSSC). During the second session, the interviewer behaved either supportively or nonsupportively. Greater acquiescence on the VSSC was associated with fewer correct responses to misleading questions about the laboratory event in the supportive and nonsupportive conditions and with more errors in response to specific questions in the nonsupportive condition. Results indicate that individual differences in children's suggestibility are related to the accuracy of their memory for separate events, although some of these relations may vary depending on the context in which children are interviewed.

The Flynn effect and U.S. policies: the impact of rising IQ scores on American society via mental retardation diagnoses.

Over the last century, IQ scores have been steadily rising, a phenomenon dubbed the Flynn effect. Because of the Flynn effect, IQ tests are periodically renormed, making them harder. Given that eligibility for mental retardation (MR) services relies heavily on IQ scores, renormed tests could have a significant impact on MR placements. In longitudinal IQ records from 9 sites around the country, students in the borderline and mild MR range lost an average of 5.6 points when retested on a renormed test and were more likely to be classified MR compared with peers retested on the same test. The magnitude of the effect is large and affects national policies on education, social security, the death penalty, and the military. This paper reports the perceptions of professionals as they relate to IQ score fluctuations in normal, borderline, and/or MR populations.

Measurement of individual differences in children's suggestibility across situations.

The authors attempted to use scores on the Video Suggestibility Scale for Children (VSSC, M. H. Scullin & S. J. Ceci, 2001) to predict 50 preschool children's performance during a field study in which they were interviewed suggestively 4 times about both a true event and a suggested event. Among the 25 children over age 4 years 6 months, tendencies on the VSSC to respond affirmatively to suggestive questions ("yield"), change answers in response to negative feedback ("shift"), and the sum of these ("total suggestibility") were all related to lack of accuracy about the true event in the field study and to both accuracy and lack of accuracy about the suggested event. Results support a 2-factor model of suggestibility.
