Stern, Florian; Kampourakis, Kostas; Müller, Andreas – Journal of Research in Science Teaching, 2023
Biology education research has shown that deeply rooted intuitions can influence students' understanding of biological phenomena. One example is design teleology, the intuition that organisms' traits were designed to fulfill a goal. Another example is psychological essentialism, the intuition that organisms have fixed essences. Past research has…

Conway, Christopher C.; Keenan-Miller, Danielle; Hammen, Constance; Lind, Penelope A.; Najman, Jake M.; Brennan, Patricia A. – Journal of Clinical Child and Adolescent Psychology, 2012
Despite consistent evidence that serotonin functioning affects stress reactivity and vulnerability to aggression, research on serotonin gene-stress interactions (G x E) in the development of aggression remains limited. The present study investigated variation in the promoter region of the serotonin transporter gene (5-HTTLPR) as a moderator of the…

Tucker-Drob, Elliot M.; Harden, K. Paige – Developmental Science, 2012
Parenting is traditionally conceptualized as an exogenous environment that affects child development. However, children can also influence the quality of parenting that they receive. Using longitudinal data from 650 identical and fraternal twin pairs, we found that, controlling for cognitive ability at age 2 years, cognitive stimulation by parents…

Liu, Xinmin; Akula, Nirmala; Skup, Martha; Brotman, Melissa A.; Leibenluft, Ellen; McMahon, Francis J. – Journal of the American Academy of Child & Adolescent Psychiatry, 2010
Objective: Functional magnetic resonance imaging is commonly used to characterize brain activity underlying a variety of psychiatric disorders. A previous functional magnetic resonance imaging study found that amygdala activation during a face-processing task differed between pediatric patients with bipolar disorder (BD) and healthy controls. We…

Smith, Lesley A.; Williams, Joanne M. – Research in Science Education, 2007
Studies from different theoretical traditions investigating children's inheritance and genetics concepts have adopted a cross-sectional method. This paper is the first to examine both cross-sectional and longitudinal changes in children's basic genetic concepts. It forms part of a larger investigation into the development of intuitive inheritance…

Dawson, Vaille – Research in Science Education, 2007
The products of modern biotechnology processes such as genetic engineering, DNA testing and cloning will increasingly impact on society. It is essential that young people have a well-developed scientific understanding of biotechnology and associated processes so that they are able to contribute to public debate and make informed personal…
