The ability of the brain to structurally and functionally alter itself is called brain plasticity. Plasticity, or the ability to change, is one of the most important aspects of neural development and regular functioning. It is also observed as a response to a change in the environment or advancing age. The potential of a person to gain cognitive skills under certain situations or conditions is termed as cognitive plasticity. These cognitive skills can be enhanced through different methods such as observational learning and practice. The study of cognitive plasticity assumes a difference between a person's current cognitive performance and their untapped potential. This book presents the complex subject of cognitive functioning and brain plasticity in the most comprehensible and easy to understand language. From theories to research to practical applications, case studies related to all contemporary topics of relevance to this field have been included in it. This book will help the readers in keeping pace with the rapid changes in this field.
