The Relationship

Age difference in the etiology of the relationship between childhood negative emotionality (NE) and conduct problems (CP) has not been previously investigated. Mothers of 662 pairs of twins completed questions on the emotionality (NE) scale of the EAS temperament survey and the CP scale of the Strengths and Difficulties Questionnaires (SDQ) via a telephone interview. Twin data were analyzed separately in younger (ages 3 to 7 years; mostly pre-schoolers) and older children (ages 8 to 13 years; mostly elementary school children). The phenotypic correlation between NE and CP increased from 0.33 among younger twins to 0.43 among older twins. Bivariate model-fitting analysis was performed to determine age difference in the etiology of the relationship between NE and CP. Among younger twins, the correlation between NE and CP was entirely explained by additive genetic factors common to NE and CP. Among older children, however, a small but significant amount of unique environmental correlation emerged to account for about 47% of the phenotypic correlation between NE and CP. The remaining 53% of the phenotypic correlation was due to shared additive genetic factors. We speculate that environmental factors associated with school adjustment may exert influences on the relationship between NE and CP among elementary school children.

Light-eyed individuals generally perform better at self-paced activities while dark-eyed individuals perform better at reactive activities. In throwing a ball at a target there were no differences between light- and dark-eyed elementary school-age children. Boys hit the target more times than did girls, and older children in upper grades hit the target more often than did younger children in lower grades.

AbstractThe present study aimed to determine the genetic and environmental etiology of the association between childhood negative emotionality (NE) and hyperactivity/inattention problems (HIP) using South Korean elementary school twins (mean age = 10.19 years, SD = 1.79 years). Telephone interviews were given to mothers of 919 twins (229 monozygotic males: 112 pairs and 5 individuals; 148 dizygotic males: 73 pairs and 2 individuals; 180 monozygotic females: 87 pairs and 6 individuals; 103 dizygotic females: 50 pairs and 3 individuals; 259 opposite-sex dizygotic twins: 127 pairs and 5 individuals) to assess their children’s NE and HIP. Consistent with prior studies, the phenotypic correlation between NE and the HIP was moderate (r = .29; 95% CI = .24, .34). Model-fitting analysis revealed that additive genetic and nonshared environmental influences on NE were .45 (95% CI [.34, .54]) and .55 (95% CI [.46, .66]), respectively, and that additive and nonadditive genetic, and nonshared environmental influences on HIP were .08 (95% CI [.03, .26]), .41 (95% CI [.21, .51]) and .51 (95% CI = .42, .61), respectively. In addition, the additive genetic correlation between NE and HIP was 1.0 (95% CI [.52, 1.00]), indicating that additive genetic factors are entirely shared between the two phenotypes. Nonadditive genetic influences were unique to HIP and not responsible for the NE-HIP association. Nonshared environmental correlation was significant but modest (re = .18, 95% CI [.06, .30]).

Experimental Group

The relationship between articulatory deficits and the development of syntax in children with severe articulation problems was investigated. Subjects in the experimental group were 30 normal elementary school children, enrolled in grades one through three, who had severe problems with articulation. Thirty normal children, free from any articulation errors, served as a control group. Children with defective articulation performed significantly less well in the areas of grammatical usage, and used shorter sentences. The relationship between phonological and syntactical errors is discussed, with implications for therapy.

The Relationship

Balance in children is one of the most important things to notice during its development. Increased risk of loss ofbalance is often associated with a slow reaction time. The purpose of this study was to determine the relationshipbetween auditory reaction time and body balance in students at Elementary School in Baha village. This research wasconducted in March 2018 with cross sectional analytic study design. Samples were taken by simple random samplingmethod with 96 samples. The sample age range is 8 - 10 years. The independent variable is auditory reaction timemeasured using computerized reaction time test software. Dependent variable is body balance measured usingPediatric Balance Scale. The relationship between two variables was analyze using Pearson Correlation test. There isa significant correlation between auditory reaction time to body balance, based on data output from analysis withsignificance <? (p = 0,006). Furthermore, based on data output known Correlation Coefficient of -0.228 which meansthe existence of negative and linear relationship. There was a significant relationship between auditory reaction timeand body balance in elementary school children in Baha Village.Keywords: Reaction Time, Auditory, Balance, Children

Decision Tasks

This study evaluated Tversky and Kahneman's model of decision framing among 90 children, 30 each from Grades 1, 3, and 6. Students were first tested to determine their level of cognitive development. They then responded to two sets of decision tasks to determine the extent to which they corresponded to Tversky and Kahneman's predicted departures from rationality. Analyses showed that older children utilized mechanisms similar to those described for adults, while first and third graders did not. There was no effect as a function of cognitive level. The implications of these findings for theory and research are discussed.
