Background: The discovery of clinical markers for specific language impairment (SLI) in children can assist in the accurate identification of children with this disorder, and in a description of the disorder's phenotype for genetic study. One challenge to this type of research is the fact that languages vary in the most salient symptoms of SLI.…

Objective: To compare the pattern of familial aggregation of psychopathology in children who are good responders (GR) to methylphenidate (MPH) versus those who are poor responders (PR). Method: A total of 118 clinically referred children ages 6 to 12 years, diagnosed with ADHD participated in a double-blind, placebo-controlled, randomized 2-week…

A single-semester elective combines Mendelian and molecular genetics in a problem-solving format. Students encounter a genetic disease scenario, construct a family pedigree, and try to confirm their medical diagnoses through laboratory experiences. Encouraged to generate ideas as they test their hypotheses, students realize the importance of data…

Background: The behaviours of 24 mothers of children with fragile X syndrome (FXS) with their affected children were examined during planned observations in their homes. The goal of this study was to describe concurrent maternal interactive behaviour and the factors that influence the type and frequency of these behaviours within this group.…

Over the past four decades, there have been numerous discussions on student achievement and school failure. Within this time, the debate over the causes and consequences of racial differences in achievement has been at the heart of the nation's social and political life. The author discusses the major developments in achievement research over the…

Pychologists, educators, and others have challenged the idea of a fixed IQ. This book uses recent research and earlier discoveries to argue that intelligence is not genetically set. Noting that the idea of learnable intelligence reflects the belief that intelligence can be taught, the book outlines a theory of learnable intelligence, including…

The hypothesis that faulty classical psychometric and sampling procedures in test construction could generate systematic bias against ethnic groups with smaller representation in the test construction sample was studied empirically. Two test construction models were developed: one with differential representation of ethnic groups (White, African…

To evaluate student learning in a computer-supported environment known as "GenScope," a system was developed for assessing students' understanding and learning of introductory genetics material presented in two developed GenScope instruments. Both quantitative and qualitative methods were used to address traditional evidential validity…

This packet contains two science learning activities that can be used in agricultural education courses. The first activity, "Using Ethanol as a Solvent," is intended to help students describe the characteristics of a solvent, to enhance student observational skills dealing with physical changes, and to demonstrate the acid or alkaline…

Research has documented the genetic contribution of paternal alcoholism and Antisocial Personality Disorder as risk factors for adolescent deviant behavior, including substance abuse. Teens (n=147) between the ages of 12 and 19 years and their parents participated in the study. The sample consisted of 74 substance abusing teens/families drawn from…

Five separate bibliographies present citations of resources regarding prenatal risk, premature and low birthweight infants, infant nutrition and breastfeeding, and early intervention for infants with disabilities. The first bibliography lists 133 references from medical texts and journals regarding child development, disabilities, diagnosis, and…

Participants in this workshop were scientists from various disciplines, including public health, oncology, nutrition, epidemiology, biochemistry, immunology, pharmacology, pediatrics, geriatric medicine, and the behavioral sciences. The workshop featured deliberations by medical experts on the dimensions and demographics of hunger in America. The…

The purpose of this investigation was to measure the attitudes of college students across the United States concerning the possible use of genetic manipulation, especially in terms of enhancing human physical and intellectual characteristics. The instrument used was divided into three general areas of inquiry: the first, designed to measure the…

The annotated bibliography of over 1,200 citations published between 1943 and 1983 is intended as a comprehensive reference guide to the scientific study of infantile autism. After a search of the literature was conducted, the information was organized by format and subject, first for journal articles (19 topics are concerned with general…

The issues of reproductive choice and domination of women through the use of reproductive technologies have placed feminists at odds with the medical profession and consumers. Inspired by the Feminist International Network of Resistance to Reproductive and Genetic Engineering (FINRRAGE), this collection of 21 essays advances a critical analysis of…
