Exploring the Boundary Conditions of the Redundancy Principle

This experiment investigated whether study of a scientific text and a visual display that contained redundant text segments would affect memory and transfer. The authors randomly assigned 42 students from a university in the southwestern United States in equal numbers to 1 of 2 conditions: (a) a redundant condition, in which participants studied a scientific text that described plate tectonics and a corresponding visual display that contained redundant segments from the text; or (b) a nonredundant condition, in which participants studied the scientific text and a corresponding visual display that lacked the redundant text segments. Embedding redundant text segments within the visual display enhanced performance on 3 measures of memory but not on a measure of transfer. The authors discuss the theoretical and practical implications using the cognitive theory of multimedia learning.     

Interactive Training Model: Enhancing Beginning Counseling Student Development

The authors propose the Interactive Training Model (ITM), a full classroom role play experience, as a method for helping student counselors develop essential interviewing and counseling skills and self‐awareness as required by the 2009 Council for Accreditation of Counseling and Related Educational Programs Standards. This pre‐post, quasiexperimental study involving 45 master's‐level students indicated that those who participated in the ITM made greater gains in supervisee development compared with those who participated in a traditional peer feedback model. Narrative student feedback regarding the use of ITM in an essential skills course is presented, and implications for counselor education are discussed.     

Contextual Variation and Memory Retrieval at Six Months

In 2 experiments we asked whether training in multiple contexts could eliminate context-dependent memory retrieval at 6 months as it does for adults. We found that 24-hour retention was disrupted when infants were trained in one context and tested in another but not when they were trained in multiple contexts prior to testing in a novel context (Experiment 1). After a long delay, however, training in multiple contexts did not facilitate memory retrieval in a novel context: An otherwise effective retrieval cue (the training mobile) did not alleviate forgetting 3 weeks later when it was presented in a novel context (Experiment 2). These findings demonstrate that multiple learning contexts can override the debilitating effects of an altered context on memory retrieval at 6 months, but only over the short term. The resistance of older memories to retrieval in novel contexts after long periods of disuse may be adaptive, insuring that potentially inappropriate or irrelevant memories will not be expressed.     

Associations Between School Readiness and Obesity‐ and Inflammation‐Related Biomarkers in Low‐Income Preschoolers Within the Healthy Kids Study

Previous research suggests obesity is negatively related to cognitive functioning and academic outcomes in addition to physical health. However, not much is known about this association in early childhood or potential physiological underpinnings. Biomarkers related to obesity have been associated with cognition, in particular the adipokine leptin, and pro‐inflammatory cytokines including interleukin‐6 (IL‐6), tumor necrosis factor‐alpha (TNF‐alpha) and C‐reactive protein (CRP). These associations may be further exacerbated for children who experience early life stress. With a sample of low‐income preschoolers, the current study examined associations between obesity‐related biomarkers and aspects of behavioral and cognitive school readiness. Partial correlations controlling for child age show hypothesized negative associations between pro‐inflammatory cytokines and school readiness, while leptin was positively associated with cognitive school readiness and body mass index (BMI) z‐score. Findings suggest connections between obesity, physiology, and school readiness need further examination, but may have implications for early childhood education and health interventions.     

An afterschool intervention program for educationally disadvantaged young children

The research investigated the premise that if educationally disadvantaged children experience increased instructional time combined with an educational setting that is sensitive to their culture and that provides perceptions of control, enhanced achievement and interest in learning will result. The research setting was the Hilltop Emergent Literacy Project (HELP), an afterschool educational program serving poor, mostly African American five- to nine-year-olds (kindergarten to third grade) who reside in a subsidized apartment complex. A treatment group of 12 kindergartners was compared to a control group of 12 kindergartners. In the spring of kindergarten, the treatment group was outperforming the control group on standardized test scores, but both groups were below national norms. In the spring of first grade, the treatment group was still outperforming the control group and was above national norms in some areas. Report card data and qualitative indicators also provide evidence of the effectiveness of the program.We thank the Hilltop Emergent Literacy Project (HELP) head teachers Teresa Bunge and Diana Reamsnyder, the HELP students, and the many graduate and undergraduate students who have served at HELP. This program was partially funded through grants from the University of Toledo, Ohio Board of Regents, General Mills Foundation, and Toledo Public Schools.     

A novel sleep optimisation programme to improve athletes’ well-being and performance

Objectives: To improve well-being and performance indicators in a group of Australian Football League (AFL) players via a six-week sleep optimisation programme. Design: Prospective intervention study following observations suggestive of reduced sleep and excessive daytime sleepiness in an AFL group. Methods: Athletes from the Adelaide Football Club were invited to participate if they had played AFL senior-level football for 1–5 years, or if they had excessive daytime sleepiness (Epworth Sleepiness Scale [ESS] >10), measured via ESS. An initial education session explained normal sleep needs, and how to achieve increased sleep duration and quality. Participants (n?=?25) received ongoing feedback on their sleep, and a mid-programme education and feedback session. Sleep duration, quality and related outcomes were measured during week one and at the conclusion of the six-week intervention period using sleep diaries, actigraphy, ESS, Pittsburgh Sleep Quality Index, Profile of Mood States, Training Distress Scale, Perceived Stress Scale and the Psychomotor Vigilance Task. Results: Sleep diaries demonstrated an increase in total sleep time of approximately 20?min (498.8?±?53.8 to 518.7?±?34.3; p?<?.05) and a 2% increase in sleep efficiency (p?<?0.05). There was a corresponding increase in vigour (p?<?0.001) and decrease in fatigue (p?<?0.05). Conclusions: Improvements in measures of sleep efficiency, fatigue and vigour indicate that a sleep optimisation programme may improve athletes’ well-being. More research is required into the effects of sleep optimisation on athletic performance.     

Art instruction and the Goodenough-Harris drawing test in fifth-graders

The experiment was conducted to assess the effect of ordinary school art instruction in human figure drawing on scores of the Goodenough-Harris Drawing Test. Subjects consisted of 44 fifth-grade students attending a suburban parochial school who were members of two preexisting, randomly assigned homeroom classes. Both classes were taught two lessons in art by their regular teachers. The treatment group was taught human figure drawing, and the control group had art lessons excluding figure drawing instruction. The Drawing Test was administered three times, one preinstruction and two postinstruction administrations. Absenteeism reduced treatment and control groups to 14 and 17 subjects, respectively. As predicted, no differences were found in the control group between pretest and postests. The treatment group showed significant gains on both posttests, as well as a significant decline from the first posttest to the second posttest.
