Learning disabilities in minority adolescents

Summary Seventy “predelinquent” disadvantaged seventh-grade students and 30 controls were compared on fifteen variables. It was found that the experimental group was significantly behind the controls in reading, grade-point-average, IQ test scores (verbal and nonverbal), as well as on measures of visual-motor and auditory perceptual functioning. It appears that the experimental youngsters display a syndrome usually considered to evidence specific learning disabilities. However, in this type of population it is difficult to separate the effects of environmentally determined deficits from inherent deficits. Therefore, it was not possible to estimate the incidence of true specific learning disabilities. On the other hand, it was suggested that regardless of the etiology of the deficits, these children could profit from the same types of educational opportunities as have been found well-suited to aid children with learning disabilities.     

The Effects of Maternal Alcohol Consumption and Cigarette Smoking during Pregnancy on Acoustic Cry Analysis

During the last trimester of pregnancy, 127 primiparous Irish mothers were interviewed to ascertain their history of alcohol and tobacco use. Confounding effects due to other drugs were not a factor in this sample. Mothers consumed an average of .21 ounces absolute alcohol (AA) per day, with 62% classified as moderate drinkers, 10.6% as heavy drinkers, and 26% as nondrinkers. Neurobehavioral status was measured using acoustic characteristics of the infant's cry, collected on the third day of life. Multiple regression analysis showed that more ounces AA per day was related to more dysphonation and higher first formant, while more cigarette smoking was related to higher pitch, higher second formant, and more variability in the second formant. Analysis of variance comparisons of these 3 alcohol groups demonstrated significant cry effects on infants of heavy drinking mothers.     

Polarization as a Function of Citizen Predispositions and Exposure to News on the Internet

Observers of democratic polities decry a seeming increase in social and political polarization. This article outlines the conditions under which Internet-based news exposure can facilitate polarization. Analyses of data from a nationally representative United States panel study reveal that frequency of news consumption over the Internet can widen disagreements between Democrats and Republicans over a wide range of social and political issues. The results reveal few signs of a similar Internet news exposure effect for disagreement linked to race and income. These findings point to some possible mechanisms of, and limitations to, processes driving social and political polarization.
