Cognitive functioning is a new and important advancement in cognitive psychology and cognitive science. Cognitive functions are a central focus in the dynamic and mediational approach to assessment and intervention. An understanding of cognitive functions is the key to the design of effective cognitive intervention and enrichment programs. This book focuses on the mind of the learner, particularly on the nature and characteristics of cognitive functioning. It covers innovative and effective approaches to the enhancement of learning potential and cognitive functioning of children and adolescents. The approaches are grounded in theories pertaining to cognitive functions, cognitive modifi ability, and dynamic assessment. Written in clear language, the book illustrates the nature of cognitive functioning and the application of certain cognitive programs and interventions across contexts. The nature of cognitive functioning today is of interest not only to cognitive psychologists but also to those working in the multiple disciplines of neuroscience, cognitive systems, and human factors design. Cognitive enrichment programs and assessment scales such as LPAD-B, FIE-B, ACFS, MindLadder, Building Blocks of Learning, and MIDAS and their applications in different environments are highlighted in the book and examples of good practice and a variety of mediational and dynamic assessment tools discussed. Educational practitioners working closely with children, counselors, parents, and caregivers will find the book a valuable reference.
