For most people, the word "pioneer" conjures up romantic visions of sturdy, courageous people who crossed physical frontiers of land and/or water alone, or who took their families, communities, and cultures with them into those uncharted territories. Once settled, their pioneering efforts shifted to starting new societies with new laws and new…

This study clarifies whether secondary school students develop their argumentation skills through reading and collaboration. The students first constructed an individual argument diagram on genetically modified organisms, read three articles, and improved their diagrams. Next, they engaged in a chat debate, reflected on their debate by…

Research spanning the fields of social, developmental, and neuropsychology provides cogent and comprehensive evidence that experiences in the very early years of a child's life serve as a foundation for later academic performance, behavior, personality, and social skills. In recent years, researchers have begun to identify complex…

Twin-study research suggests that many (but not all) of the same genes contribute to genetic influence on diverse learning abilities and disabilities, a hypothesis called "generalist genes". This generalist genes hypothesis was tested using a set of 10 DNA markers (single nucleotide polymorphisms [SNPs]) found to be associated with early reading…

Objective: To explore the contributions of genetic and environmental influences to individual variation and covariation of the Child Behavior Checklist (CBCL) DSM-oriented scales (DOS) originally proposed by Achenbach and associates in 2001. Method: A classic twin study of 398 twin pairs ages 8 to 17 years belonging to the population-based Italian…

In a longitudinal genetic study we explored which factors underlie stability in verbal and nonverbal abilities, and the extent to which the association between these abilities becomes stronger as children grow older. Measures of verbal and nonverbal IQ were collected in Dutch twin pairs at age 5, 7, 10, 12 and 18 years. The stability of both…

This article provides snapshots of recent events and programs at colleges and universities in the state of California: (1) A graduate student in kinesiology at California State University, Chico, is talking the talk and walking the walk to promote physical fitness; (2) First-generation Latino students enrolled in nutrition science and health…

Background: Few studies have investigated functional and behavioural variables of Cornelia de Lange Syndrome (CdLS) in a large sample of individuals. The aim of this study is to provide greater insight into the clinical, behavioural and cognitive characteristics that are associated with CdLS. Methods: In total, 56 individuals with CdLS…

Increasingly, researchers in the areas of eating disorders and obesity prevention are recognizing the benefits of collaborative efforts aimed at curbing the spectrum of eating-related disturbances. Research suggests that eating disorders and overweight tend to co-occur, and that individuals cross over from one eating-related disturbance to…

The authors assessed 2,502 ten-year-old children, members of 1,251 pairs of twins, on a Web-based battery of problems from 5 diverse aspects of mathematics assessed as part of the U.K. national curriculum. This 1st genetic study into the etiology of variation in different domains of mathematics showed that the heritability estimates were moderate…

This investigation examined how personal, environmental and substance use factors predicted psychosocial functioning for youth with alcohol and drug problems. Four hundred twenty-four adolescents (M = 15.9, SD = 1.3) completed comprehensive assessments, including personal characteristics (e.g., Axis I diagnosis, motivation, self-esteem),…

During a class discussion, a professor placed a quote on the overhead by Lewis Terman, former Stanford professor, APA president, and vicar of IQ testing and gifted education in America. The passage stressed that Mexicans and Blacks are born morons, not capable of learning, and should be segregated from Anglos in special classes. In addition, in…

This study examined university students' knowledge of and attitudes (n = 378) toward biotechnology in Slovakia, a conservative country where the distribution of genetically engineered products are banned by law. We found a significant positive correlation between attitudes and the level of knowledge; however, although students enrolled in biology…

Human Biology courses are typically offered for non-biology majors who, like students in high school biology courses, have varying degrees of motivation and background. The primary focus is on explaining the biology behind human health and disease, but human ecology, human evolution, and human genetics may also be covered. Hence, Human Biology…

This study examined 3-year-old children who were classified as hyperactive (HYP), oppositional-defiant (OD), hyperactive and oppositional defiant (HYP/OD), and non-problem based on mothers' reports of behavior. Using fathers', teachers', and observers' ratings of children's behavior, concurrent validity was excellent for the HYP/OD group, moderate…
