Modifying Knowledge, Emotions, and Attitudes Regarding Genetically Modified Foods
Peer reviewed Peer reviewed
Direct linkDirect link
Heddy, Benjamin C.; Danielson, Robert W.; Sinatra, Gale M.; Graham, Jesse – Journal of Experimental Education, 2017
The purpose of this study was to explore whether conceptual change predicted emotional and attitudinal change while learning about genetically modified foods (GMFs). Participants were 322 college students; half read a refutation text designed to shift conceptual knowledge, emotions, and attitudes, while the other half served as a control group.…

Peer reviewed Peer reviewed

Prevost, Luanna B.; Smith, Michelle K.; Knight, Jennifer K. – CBE - Life Sciences Education, 2016
Previous work has shown that students have persistent difficulties in understanding how central dogma processes can be affected by a stop codon mutation. To explore these difficulties, we modified two multiple-choice questions from the Genetics Concept Assessment into three open-ended questions that asked students to write about how a stop codon…

Development of a "Lac" Operon Concept Inventory (LOCI)
Peer reviewed Peer reviewed

Stefanski, Katherine M.; Gardner, Grant E.; Seipelt-Thiemann, Rebecca L. – CBE - Life Sciences Education, 2016
Concept inventories (CIs) are valuable tools for educators that assess student achievement and identify misconceptions held by students. Results of student responses can be used to adjust or develop new instructional methods for a given topic. The regulation of gene expression in both prokaryotes and eukaryotes is an important concept in genetics…

Identity and Epistemic Emotions during Knowledge Revision: A Potential Account for the Backfire Effect
Peer reviewed Peer reviewed
Direct linkDirect link
Trevors, Gregory J.; Muis, Krista R.; Pekrun, Reinhard; Sinatra, Gale M.; Winne, Philip H. – Discourse Processes: A multidisciplinary journal, 2016
Recent research has shown that for some topics, messages to refute and revise misconceptions may backfire. The current research offers one possible account for this backfire effect (i.e., the ironic strengthening of belief in erroneous information after an attempted refutation) from an educational psychology perspective and examines whether…

Motor Impulsivity during Childhood and Adolescence: A Longitudinal Biometric Analysis of the Go/No-Go Task in 9- to 18-Year-Old Twins
Peer reviewed Peer reviewed
Direct linkDirect link
Bezdjian, Serena; Tuvblad, Catherine; Wang, Pan; Raine, Adrian; Baker, Laura A. – Developmental Psychology, 2014
In the present study, we investigated genetic and environmental effects on motor impulsivity from childhood to late adolescence using a longitudinal sample of twins from ages 9 to 18 years. Motor impulsivity was assessed using errors of commission (no-go errors) in a visual go/no-go task at 4 time points: ages 9-10, 11-13, 14-15, and 16-18 years.…

Patterns and Sources of Continuity and Change of Energetic and Temporal Aspects of Temperament in Adulthood: A Longitudinal Twin Study of Self- and Peer Reports
Peer reviewed Peer reviewed
Direct linkDirect link
Kandler, Christian; Riemann, Rainer; Angleitner, Alois – Developmental Psychology, 2013
This study investigated the mean-level and individual-level trends as well as the genetic and environmental sources of rank-order continuity and change in temperament traits ("Briskness, Perseveration, Sensory Sensitivity, Emotional Reactivity, Endurance, and Activity"). We analyzed self-reports and peer ratings from 2 adult age groups…
