Experimental evidence for diagramming benefits in science writing

Arguing for the need for a scientific research study (i.e. writing an introduction to a research paper) poses significant challenges for students. When faced with these challenges, students often generate overly safe replications (i.e. fail to find and include opposition to their hypothesis) or in contrast include no strong support for their hypothesis (i.e. relevant, valid evidence). How can we support novice scientists in generating and defending high quality hypotheses? A long history of research supports the affordances provided by structured representations of complex information. More recently, argument diagramming has gained traction in instruction for philosophy, social studies, and law. However, its effectiveness for supporting students in science is relatively untested. The purpose of the current study was to test the effectiveness of a simple argument diagram optimized for supporting students’ research writing in psychology. Two groups of undergraduate students in research methods lab courses were randomly assigned to diagramming support or no support. In the research papers, those given diagramming support were more likely to argue for an appropriately ‘risky’ hypothesis and wrote more about the relevance and validity of cited studies. Some of these gains show signs of transfer to a second paper written later in the course that did not require use of the diagramming tool.     

Interference control in a new rule use task: age-related changes, labeling, and attention

Three experiments examined 3- to 6-year-olds' interference control using a task in which children saw 2 corresponding sets of colored cards, a large set in front of them and a small set behind them. A colored candy (Smartie) was placed on a large card with mismatching color, and children could win the Smartie by selecting the small card that matched the color of the large card. Three-year-olds performed poorly whereas older children performed well. Having children label the correct color before responding improved 3-year-olds' performance (Experiment 2), as did pointing to the large card (Experiment 3); decreasing the affective salience of the stimuli (colored beads vs. Smarties) did not (Experiment 3). Results reveal the role of selective attention in action control.     

The development of visual short-term memory capacity in infants

Four experiments assessed visual short-term memory capacity in 4- to 13-month-old infants by comparing their looking to changing and nonchanging stimulus streams presented side by side. In each stream, 1 to 6 colored squares repeatedly appeared and disappeared. In changing streams, the color of a different randomly chosen square changed each time the display reappeared; the colors remained the same in nonchanging streams. Infants should look longer at changing streams, but only if they can remember the colors of the squares. The youngest infants preferred changing streams only when the displays contained one object, whereas older infants preferred changing streams when the displays contained up to 4 objects. Thus, visual short-term memory capacity increases significantly across the first year of life.     

Parent Autonomy Support,Academic Achievement,and Psychosocial Functioning: a Meta-analysis of Research

A meta-analysis of 36 studies examining the relations between parent autonomy support (PAS) and child outcomes indicated that PAS was related to greater academic achievement and indicators of adaptive psychosocial functioning, including autonomous motivation, psychological health, perceived competence, engagement, and positive attitudes toward school, among other outcomes. The strongest relation emerged between PAS and psychological health. Results indicated that the strength of the PAS relation was stronger when PAS was reflective of both parents, rather than of just mothers or just fathers among five of six outcomes for which moderators could be examined. Moderator analyses also suggested that PAS correlations are stronger when the outcome is better aligned to the predictor and the relation between PAS and psychosocial outcomes may vary by grade level. Implications for theory and future research are discussed.
