The Long Term Retention Of Knowledge And Skills

This report reviews factors that influence how well knowledge and skills are retained over relatively long periods of nonuse. A cognitively oriented interpretation is applied to prior findings and beliefs about the nature of long-term retention. The report identifies instructional strategies (conditions of learning) which promote long-term retention and do not have an adverse impact on learning.

A. INTRODUCTION AND BACKGROUNDl,2 This report reviews and interprets research on the nature and magnitude of the effects of those factors which influence how well knowledge and skills (K&S) are retained over relatively long periods of nonuse. Our interest lies in the kinds of knowledge domains and skills that military personnel must master to function effectively on their jobs. The practical concern impelling this study is that K&S degradation or loss (which we will refer to as "decay") can and does occur, often and severely enough, to jeopardize military preparedness. There are occasions in all the military services when personnel who have just completed their training do not receive an opportunity to practice or use their new capabilities for weeks or months. In the case of reservists who may be called back to active duty, the period of nonuse of relevant military job skills may be counted in terms of years. B. OBJECTIVES The overall objective is to critically analyze the relevant scientific literature which relates the processes involved in learning to those of memory, taking into account the characteristics of the learner and the learning tasks. More specifically, we have focused on the following sub-objectives: 1. Identify, describe and rank the influence and the interactions of the important major variables that affect long-term retention (LTR); 1 I am indebted to Dr. Jesse Orlansky, Institute for Defense Analyses, for his encouragement and guidance through all phases of this report.

The archer stands and pulls back the bow, visualizing the path of the arrow to the target. Does this mental exercise enhance performance? Can we all use such techniques to improve performance in our daily lives? In the Mind's Eye addresses these and other intriguing questions. This volume considers basic issues of performance, exploring how techniques for quick learning affect long-term retention, whether an expert's behavior can serve as a model for beginners, if team performance is the sum of individual members' performances, and whether subliminal learning has a basis in science. The book also considers meditation and some other pain control techniques. Deceit and the ability to detect deception are explored in detail. In the area of self-assessment techniques for career development, the volume evaluates the widely used Myers-Briggs Type Indicator.

The Psychology of Learning and Motivation publishes empirical and theoretical contributions in cognitive and experimental psychology, ranging from classical and instrumental conditioning to complex learning and problem solving. Each chapter provides a thoughtful integration of a body of work. Volume 41 includes in its coverage chapters on multimedia learning, brain imaging, and memory, among others.

By analyzing the results of experiments that use a wide variety of training tasks including those that were predominantly perceptual, cognitive, or motoric, this volume answers such questions as: Why do some people forget certain skills faster than others? What kind of training helps people retain new skills longer? Inspired by the work of Harry Bahrick and the concept of "permastore," the contributors explore the Stroop effect, mental calculation, vocabulary retention, contextual interference effects, autobiographical memory, and target detection. They also summarize an investigation on specificity and transfer in choice reaction time tasks. In each chapter, the authors explore how the degree to which reinstatement of training procedures during retention and transfer tests accounts for both durability and specificity of training. Researchers and administrators in education and training will find important implications in this book for enhancing the retention of knowledge of skills. "You have to read this book. Anyone interested in training will want to read it. This book provides the theoretical bases of the acquisition of durable skills for the next decade. It advances and demonstrates a new principle of skill learning that will prove to be as important as the encoding specificity principle and its corollary, the principle of transfer appropriate processing. This new principle is that highly practiced skill learning will be durable when the retention test embodies the procedures employed during acquisition. This principle, and the other important findings reported in this text, will have a great impact on the evolution of memory theory and on the wide range of applications." --Douglas Hermann, University of Maryland

To most of us, learning something "the hard way" implies wasted time and effort. Good teaching, we believe, should be creatively tailored to the different learning styles of students and should use strategies that make learning easier. Make It Stick turns fashionable ideas like these on their head. Drawing on recent discoveries in cognitive psychology and other disciplines, the authors offer concrete techniques for becoming more productive learners. Memory plays a central role in our ability to carry out complex cognitive tasks, such as applying knowledge to problems never before encountered and drawing inferences from facts already known. New insights into how memory is encoded, consolidated, and later retrieved have led to a better understanding of how we learn. Grappling with the impediments that make learning challenging leads both to more complex mastery and better retention of what was learned. Many common study habits and practice routines turn out to be counterproductive. Underlining and highlighting, rereading, cramming, and single-minded repetition of new skills create the illusion of mastery, but gains fade quickly. More complex and durable learning come from self-testing, introducing certain difficulties in practice, waiting to re-study new material until a little forgetting has set in, and interleaving the practice of one skill or topic with another. Speaking most urgently to students, teachers, trainers, and athletes, Make It Stick will appeal to all those interested in the challenge of lifelong learning and self-improvement.
