The geometric module in the rat: independence of shape and feature learning in a food finding task

Rats found food in a rectangular enclosure in three experiments testing how learning about a distinctive feature near a goal interacts with learning based on the geometry of an enclosure. Rats trained to follow a feature in square and triangular enclosures and to use geometry in the rectangle followed the feature when it was in the rectangle (Experiment 1). Rats trained with the feature in a geometrically consistent corner of the rectangle learned about both geometry and the feature (Experiment 2). Training with the feature in the square did not block learning of geometry when both predicted the location of food in the rectangle (Experiment 3). The “geometric module” (Cheng, 1986) may have a special status in spatial learning.     

Cognitive complexity,the first year of teaching,and mentoring

Drawing on data from a US study of nine mentors and mentees, including mentee scores on the Reasoning about Current Issues (RCI) Test, which offers a measure of cognitive complexity, the authors explore how differences in cognitive complexity were related to role expectations, conceptions of teaching problems, and the use of evidence for justifying beliefs. Growing out of the Reflective Judgment Model developed by King and Kitchner [(2002). The reflective judgment model: Twenty years of research on epistemic cognition. In B. Hofer, & P. Pintrich (Eds.), Personal epistemology: The psychology of beliefs about knowledge and knowing (pp. 37–61). Mahwah, NJ: Lawrence Erlbaum Associates] the RCI defines cognitive complexity in terms of how individuals reason—make judgments and use evidence—about ill-structured, controversial, problems. The authors argue that differences in how individuals reason when problem solving may help explain some aspects of how relationships between mentees and mentors form and suggest that greater attention needs to be given to cognitive complexity when designing induction and mentor programs.     

Mental health services for people who are deaf

The issue of mental health services available to adults and children in the United States who are deaf is addressed. Included is a historical perspective on the changes in these services over the last 50 years. Within this scope, the current status of services is described in some detail. Psychological research on children who are deaf is reviewed, and current issues faced by school psychology and psychologists who evaluate deaf children in school settings are examined. The disturbing current trend toward the criminalization of people with mental illness, which affects both hearing and deaf adults with psychiatric diagnoses, is covered. Suggestions are made for improving mental health services for children and adults who are deaf.

Assessing Readiness for E‐Learning

ABSTRACT Today, e‐learning is a common delivery media for education and training within many organizations. Yet, while both the supply and demand for e‐learning opportunities has risen in recent years, many professionals are beginning to question whether e‐learn‐ers are prepared to be successful in an online learning environment (e.g., Gug‐lielmino & Guglielmino, 2003; Watkins & Corry, 2005). After all, a learner's demonstrated success in a conventional education and training classroom may not be an adequate predictor of success in an e‐learning classroom. One way of gauging a potential online learner's readiness is through self‐assessment. As a first step in defining an instrument that measures an e‐learner's readiness, with the cooperation of volunteer participants from the U.S. Coast Guard, this study looked into the validity and internal consistency of items within a self‐assessment of e‐learning readiness that is under development, and provided data for the continuing development and revision of the instrument. Having demonstrated evidence of internal consistency and construct validity, the self‐assessment now provides a tool for continuing research into the prediction of e‐learning performance. Funding for this study was provided by the International Society for Performance Improvement.     

The great leap backward: changes in the jumping performance of Australian children aged 11−12-years between 1985 and 2015

Previous data have indicated relative stability over time of paediatric jumping performance, but few data exist since the early 2000s. This study quantified the 30-year secular changes in jumping performance of Australian children aged 11?12-years using data from the Australian Schools Health and Fitness Survey (1985, n = 1967) and Growing Up in Australia’s Child Health CheckPoint (2015, n = 1765). Both cohorts measured jumping performance (standing long jump distance), anthropometric and demographic data. Secular changes in jumping performance means and quantiles were examined using multivariable linear and quantile regression. Between 1985 and 2015, jumping performance declined by 16.4 cm or by 11.2% (standardised change 0.66 SD, 95%CI 0.60 to 0.73). Adjustment for body mass reduced the effect by 32%, although the decline remained (absolute change – 11.1 cm, 95%CI ?12.5 to ?9.7; percent change 7.7%, 95%CI 6.7 to 8.6; standardised change 0.51 SD, 95%CI 0.44 to 0.57). This decline was evident across all quantiles. The jumping performance of Australian children aged 11?12-years has declined between 1985 and 2015, with body mass changes accounting for only part of the decline. Efforts should continue to promote paediatric muscular fitness, reduce adiposity, and aim to reverse this decline in jumping performance.     

Practical considerations when using pedometers to assess physical activity in population studies: lessons from the Burnie Take Heart Study

The aim of this study was to summarize both practical and methodological issues in using pedometers to assess physical activity in a large epidemiologic study. As part of a population-based survey of cardiovascular disease risk factors, physical activity was assessed using pedometers and activity diaries in 775 men and women ages 25-64 years who were residents of Burnie, Tasmania, 1998-99. Common data problems were classified by type. The frequency of each problem and the methods used to identify it are reported along with strategies to correct or prevent each problem type. Pedometer data from 15 (1.9%) participants could not be used due to errors in completing the pedometer protocol. Among 760 participants with usable data, the median number of steps was 9,729 for men and 10,388 for women. Pedometer steps per day were modestly correlated (r = .20, p < .0001) with the duration of pedometer wear, which ranged from 4.50 to 21.75 hr. Adjustment for wear time, however, did not alter observed correlations between pedometer steps and cardiovascular risk factors. The authors conclude that pedometers can be used in large population studies with a relatively low frequency of data errors. However guidelines for consistent data collection and interpretation are needed.
