Continuities and discontinuities in the development of 64 very small premature infants to 4 years of age.

The psychiatric, psychological, school and overall family functioning of 64 very small premature infants was assessed from birth up to 48 mnths of age. Results indicated that 43% of infants scored in the abnormal range on a behaviour rating scale filled in by the mothers and 24% on a teacher rating scale at age 4. However, only 11% of the children received a psychiatric diagnosis. Traditional attachment ratings at 1 yr were not related to psychiatric status at age 4, but family functioning was. Disturbed children had also suffered more perinatal difficulties.

Neuropsychologic and academic functioning of children with sickle cell anemia.

This study compared neuropsychologic test results and academic functioning among 28 school-age children with sickle cell anemia (SCA), and 28 healthy, age-, sex-, and socioeconomically matched black peers followed at a tertiary care center. Children with SCA scored significantly lower on reading and spelling achievement scores than healthy matched peers. Also, older children with SCA performed significantly less well on tests of visual-motor and attention skills than younger children with SCA. These results were unrelated to most measures of physical illness severity. The data suggest that sickle cell anemia may be associated with subtle neuropsychological and learning deficits that can contribute to decreased school performance.

G.H. Mead's social behaviorism.

This paper seeks to clarify those conceptual foundations of G.H. Mead's social behaviorism which are assumed, but not made explicit, in that writer's well-known volume Mind, Self and Society. These foundations are shown to be an outgrowth of Mead's early commitment to the organic conception of conduct underlying the psychological functionalism of the Chicago School. Further light is shed upon Mead's position by pointing out the fundamental differences between his model of conduct and that characteristic of the behaviorist tradition in American psychology.

Dystonia--L-dopa responsive or juvenile parkinsonism?

Four cases of dystonia occurring in two families are reported. The first symptoms consisting of dystonia and rigidity appeared early in childhood, in the first months in one family and of ages two and five years respectively in the other. In two cases, transient tremor was noted. These four children have been treated with L-dopa with prompt spectacular results, in cases 1 and 2, with more gradual less complete results in the others. L-dopa treatment was continued twelve, eleven, six, and five years, respectively, without any developmental problems. Motor function remains satisfactory and school work is normal. The only secondary effect observed was the occurrence of dyskinesia. The relation between L-dopa responsive dystonia and Parkinson's disease is discussed.

Evolution of a successful community bicycle helmet campaign.

BACKGROUND: Bicycling injuries claim more than 900 lives each year in the United States, and the major cause of deaths is head injuries. Bicycle helmets can prevent head and brain injuries, yet helmet use rate remains low. Helmets are expensive, and their cost can be prohibitive. This study asks the question, "If bicycle helmets are made affordable, will they be worn?" METHODS: A multifaceted bicycle helmet campaign was begun in Grand Junction, Colorado, population 76,000, in 1992 and was evaluated after its first 2 years. The educational component involved presentations in local schools and at community functions, physician education, and media promotions. A discount helmet program was established through community donations, which allowed helmets to be sold to low-income families for $5 and to middle- and upper-income families for $15; approximately 2400 helmets were sold. One year later a local retailer sold helmets for $12.99; approximately 4000 helmets were sold. RESULTS: Twenty-three locations were surveyed in 3 consecutive years by observers looking for bicycle riders and the presence or absence of helmets. The base-line overall use rate in 1992 was 9.9 percent, which increased to 20.9 percent in 1993 and to 37.1 percent in 1994. There were increases in helmet use in all age groups. CONCLUSIONS: A community bicycle helmet campaign that combines affordable helmets with appropriate education can effect an increase in helmet use. A major key to a successful program is a local retailer willing to sacrifice profits to promote helmet sales and use.

Together wherever we go: the ethnographic child and the developmentalist.

Krackow and Gordon aim to refute the slot-filler (SF) model of taxonomic knowledge development. On this model, preschoolers derive "slot-filler" categories from event schemas. SF categories are items that fill the slots created by the actions or functions within an event. They combine into coordinate categories, based on general functions, in the school-aged years. This model, which has received considerable empirical support across methodologies, ages, and sociocultural contexts, relies on the "ethnographic child"--one who has knowledge of and participates in a sociocultural world. The SF account is not disproved by Krackow and Gordon, which offers no new or alternative category development account. Their method and theorizing are a poor fit to children, ethnographic or otherwise, undermining the study's capacity to say something reliable and representative about cognition in preschoolers. Moreover, if the data are to be relied on, they are supportive of the SF model.

Executive functions and performance on high-stakes testing in children from urban schools.

High-stakes achievement testing is a centerpiece of education reform. Children from socially disadvantaged backgrounds typically perform more poorly than their more advantaged peers. The authors evaluated 91 fifth-grade children from low-income urban schools using clinical neuropsychological tests and behavioral questionnaires and obtained fourth-grade scores on state mandated standards-based testing. Goals were to determine whether executive functions are selectively diminished in children from poor urban environments and to evaluate to what extent integrity of executive functions is associated with test scores. Neuropsychological variables (particularly executive functions) accounted for 40% of the variance in English scores and 30% in mathematics. Efforts to improve children's academic achievement should consider developmental factors as well as curricular content.

A multivariate prediction model of schizophrenia.

Univariate prediction models of schizophrenia may be adequate for hypothesis testing but are narrowly focused and limited in predictive efficacy. Therefore, we used a multivariate design to maximize the prediction of schizophrenia from premorbid measures and to evaluate the relative importance of various predictors. Two hundred twelve Danish subjects with at least one parent diagnosed in the schizophrenia spectrum (high risk) and 99 matched subjects with no such parent (low risk) were assessed on 25 premorbid variables in seven domains (genetic risk, birth factors, autonomic responsiveness, cognitive functioning, rearing environment, personality, and school behavior) when the subjects averaged 15 years of age. Twenty-five years later, 33 subjects had received lifetime diagnoses of schizophrenia. Discriminant function analyses were used to discriminate schizophrenia outcomes from no mental illness and nonschizophrenia outcomes on the basis of premorbid measures. Regardless of the comparison group used, schizophrenia was predicted by the interaction of genetic risk with rearing environment, and disruptive school behavior. Within the high-risk group, two-thirds of schizophrenia outcomes were correctly predicted by these premorbid measures; three-quarters of those with no mental illness were also correctly predicted. Prediction was enhanced among those with two schizophrenia spectrum parents, lending support to a multiplicative gene x environment model. Implications for early identification/primary prevention efforts are discussed.

New morbidity-problems and peer relations in a sample of Swedish primary school children: a follow-up from the first to the third grade.

The stability in the new morbidity-problem domains motor skills, reading/writing ability, behavioral-psychological-social function and concentration ability in school, and the stability of peer status and peer preferences as well as relationships between peer status and problems among boys and girls was studied in a sample of 81 Swedish primary school children. The children were rated by teachers and made peer nominations six months after school start, and in the third grade. There was considerable stability in problems, while the stability in peer status was modest. There were marked gender differences. Boys in contrast to girls improved in motor skills from the first to the third grade, and boys had more concentration problems and multiple problems than girls in both grades 1 and 3. In the first grade low peer acceptance in boys was accompanied by low motor skills. In the third grade, low peer acceptance in boys was accompanied by deficient concentration ability and externalizing problems. For girls, few relationships between low peer acceptance and problems emerged Various explanations for these findings are discussed.

Impact of lead exposure on health status and scholastic achievement of school pupils in Alexandria.

Lead exposure among children is a serious health problem affecting virtually every system in their bodies. Affection of their cognitive function with its implication of poor school performance, is one of the serious outcomes of such exposure. In an attempt to arrive to an adequate knowledge about the impact of lead exposure on the health status and scholastic achievement in school age, a cross sectional study was carried out on 250 primary school pupils aged from 8 to 10 years in Wassat region in Alexandria. The concentration, visual and hearing acuity and the cognitive function. Moreover, laboratory investigation of blood lead level of the pupils was carried out. Their final scholastic achievement at the end of the year were recorded. The results indicated that the mean blood lead level among the studied pupils was 17.36 +/- 10.67 microg/dl, more than one third of the sample (36.00%) were highly exposed to lead with blood level of 20 microg/dl and more. A significant negative correlation was found between blood lead level and the 50th percentile of weight for height (r = -0.4488), haemoglobin concentration (r = -0.6133) and IQ scores (r = -0.8150) of the pupils. While a significant positive correlation was observed with the functional visual and hearing loss (r = 0.1390 and 0.2189 respectively). Moreover, the multiple regression analysis determined that age, blood lead level, crowding index, IQ score and number of missed school days were the significant contributing variables to the final scholastic achievement of the pupils from all the studied factors.

Cognitive and motor functions of iodine-deficient but euthyroid children in Bangladesh do not benefit from iodized poppy seed oil (Lipiodol).

Iodine supplementation before pregnancy in iodine-deficient women prevents cretinism and neuromotor deficits in their offspring. It is unclear whether iodine supplementation benefits cognitive function in iodine-deficient school-aged children. We therefore conducted a double-blind, randomized, controlled trial of the effects of iodized poppy seed oil (Lipiodol) on cognitive and motor function and weight gain of iodine-deficient school children. The study was conducted with 305 children in grades 1 and 2 from 10 primary schools in two iodine-deficient areas in Bangladesh. The children were stratified by school and grade and randomly assigned to receive 400 mg of oral Lipiodol or a placebo. All children were given a battery of cognitive and motor function tests and had their weights, serum thyroxine (T4) and thyroid-stimulating hormone (TSH) and urinary iodine levels measured before and 4 mo after the intervention. On enrollment, both groups were moderately iodine deficient (median urinary iodine values: placebo group = 3.3 micromol/L, n = 148; iodine group = 3.1 micromol/L, n = 152; goiter prevalence in both groups >95%). However, their T4 and TSH levels were within the normal range. After 4 mo, there was a significant treatment effect on urinary iodine levels (P < 0.0001), but the levels of the treated group were still below normal (median = 7.9 micromol/L). No significant differences were found in T4 and TSH levels, weight gain, cognitive or motor function. The findings suggest that Lipiodol supplementation in moderately iodine-deficient children with normal T4 levels is unlikely to benefit their cognitive function. However, it remains possible that other iodine preparations may have benefits.

Teachers' perceptions of maladaptive behaviour in Lebanese refugee children.

Research on the psychological status of children who are refugees from war has led to varying results. Children from war conditions or who have been subject to evacuation have been shown to have relatively low levels of disturbed behaviour, have internalising symptoms of anxiety or depression, display behaviour with aggressive features, and suffer slight psychological disturbance, depending on their caretakers' response to the stressful experience. Based on the contrasting evidence and observations within an inner Melbourne Muslim school, this study aimed to determine whether more behaviour problems existed in Muslim children from Lebanese families. Compared with other war refugee Muslim immigrant children, Lebanese children were not found to be more aggressive, but were more anxious. Lebanese males displayed more inattentive behaviour at school than non-Lebanese males. Sex differences were found in adaptive functioning within Lebanese and non-Lebanese groups. Differences in school performance and adaptive functioning were found between Lebanese and normative samples when males and females were analysed separately. These results are discussed in the context of teacher expectations and perceptions of culturally acceptable behaviour.
