Busstra, Maria C.; Hartog, Rob; Kersten, Sander; Muller, Michael – Advances in Physiology Education, 2007
Nutritional genomics, or nutrigenomics, can be considered as the combination of molecular nutrition and genomics. Students who attend courses in nutrigenomics differ with respect to their prior knowledge. This study describes digital nutrigenomics learning material suitable for students from various backgrounds and provides design guidelines for…

Gray, Jeffrey J. – Chemical Engineering Education, 2006
I present modifications to the traditional course entitled, "Process dynamics and control," which I renamed "Modeling, dynamics, and control of chemical and biological processes." Additions include the central dogma of biology, pharmacokinetic systems, population balances, control of gene transcription, and large­-scale…

Chaudhry, M. Ahmad – Biochemistry and Molecular Biology Education, 2006
The expression of genes in cells of various tissue types varies considerably and is correlated with the function of a particular organ. The pattern of gene expression changes in diseased tissues, in response to therapy or infection and exposure to environmental mutagens, chemicals, ultraviolet light, and ionizing radiation. To better understand…

Bonner, Janice M.; Holliday, William G. – Journal of Research in Science Teaching, 2006
A composite theory of college science student note-taking strategies was derived from a periodic series of five interviews with 23 students and with other variables, including original and final versions of notes analyzed during a semester-long genetics course. This evolving composite theory was later compared with Van Meter, Yokoi, and Pressley's…

Polderman, Tinca J. C.; Stins, John F.; Posthuma, Danielle; Gosso, M. Florencia; Verhulst, Frank C.; Boomsma, Dorret I. – Intelligence, 2006
This study examined the phenotypic and genotypic relationship between working memory speed (WMS) and working memory capacity (WMC) in 12-year-old twins and their siblings (N = 409). To asses WMS all children performed a reaction time task with three memory loads from which a basic mental speed measure and the derived slope were used. WMC was…

Pata, Kai; Sarapuu, Tago – International Journal of Science Education, 2006
This study investigated the possible activation of different types of model-based reasoning processes in two learning settings, and the influence of various terms of reasoning on the learners' problem representation development. Changes in 53 students' problem representations about genetic issue were analysed while they worked with different…

Bolte, Sven; Poustka, Fritz – Journal of Child Psychology and Psychiatry, 2006
Background: The objective of this study was to investigate the tendency for local processing style ("weak central coherence") and executive dysfunction in parents of subjects with an autism spectrum disorder (ASD) compared with parents of individuals with early onset schizophrenia (EOS) and mental retardation (MR). Method: Sixty-two…

Sternberg, Robert J.; Grigorenko, Elena L.; Kidd, Kenneth K. – American Psychologist, 2006
This article presents replies to published comments on the authors' original article (R. L. Sternberg, E. L. Grigorenko, and K. K. Kidd. G. Carey cited in his response to their article a study by Tang et al. (2005) showing that "of 3,636 subjects of varying race/ethnicity, only 5 (0.14%) showed genetic cluster membership different from their…

Finkel, Deborah; Reynolds, Chandra A.; Berg, Stig; Pedersen, Nancy L. – International Journal of Aging and Human Development, 2006
Sex differences in the etiology of normal cognitive functioning in aging remain largely unexplored. We conducted an investigation of genetic and environmental contributions to sex differences in level of cognitive performance and rate of decline in the Swedish Adoption/Twin Study of Aging (SATSA) (Finkel & Pedersen, 2004) data set. Behavioral…

Elwess, Nancy L.; Edwards, Felecia; Latourelle, Sandra M. – Bioscene: Journal of College Biology Teaching, 2006
Up until a short time ago the Y chromosome played the role of the juvenile delinquent within human chromosomes. It was considered to be rich in junk, short on genes, and rapidly degenerating. Now the Y chromosome is growing up by providing a means for investigating human migration. Through the use of genetic markers on the Y chromosomes, students…

Muris, Peter – International Journal of Behavioral Development, 2006
Anxiety disorders are among the most prevalent psychiatric problems in children and adolescents. The present article summarizes the main evidence that has accumulated on the pathogenesis of childhood anxiety disorders during the past two decades. Various risk and vulnerability factors (e.g., genetics, behavioral inhibition, disgust sensitivity,…

Stromswold, Karin – Cognition, 2006
Results of twin studies clearly demonstrate that genetic factors play an important role in the rate of language acquisition and linguistic proficiency attained by normal and impaired children and adults [see Stromswold, K. (2001). The heritability of language: A review and meta-analysis of twin, adoption and linkage studies. "Language," 77,…

Objective: The authors explored genetic moderators of symptom reduction and side effects in methylphenidate-treated preschool-age children diagnosed with attention-deficit/hyperactivity disorder (ADHD). Method: DNA was isolated from 81 subjects in a double-blind, placebo-controlled, crossover methylphenidate titration. Parents and teachers…

Fearon, R. M. Pasco; Van IJzendoorn, Marinus H.; Fonagy, Peter; Bakermans-Kranenburg, Marian J.; Schuengel, Carlo; Bokhorst, Caroline L. – Developmental Psychology, 2006
The current article presents results from a twin study of genetic and environmental components of maternal sensitivity and infant attachment and their association. The sample consisted of 136 twin pairs from 2 sites: Leiden, the Netherlands, and London, UK. Maternal sensitivity was assessed in the home at 9-10 months, and infant attachment…

Richardson, Dana – 1996
Stuttering is a complex condition, and, in the past, there was not significant evidence to prove any one theory as to its cause. Most researchers now agree that stuttering is mainly a genetic disorder that is sometimes aggravated or brought on by developmental and environmental factors. In genetic research there have been studies on families in…
