| Abstract | The magnetic resonance imaging (MRI) machine itself has an impact on the likelihood of obtaining successful measurements of brain size in certain groups of subjects. The differential selection and attrition in both cross-sectional and longitudinal designs, therefore, indicate that the MRI coincidentally serves as a screen for the anatomical structure of the brains that are successfully scanned. This screening effect introduces confounds in experiments whose very hypotheses are focused on comparing anatomical differences in subjects who differ, for example, in their reactions to anxiety-inducing situations. Here, behavioral interventions and possible statistical models are presented in order to reduce attrition and other effects of the confounds introduced by the MRI measurement process in research. Child and adolescent research—particularly in the attention-deficit/hyperactivity disorder research area—is used as an example to clarify and delineate the general research principles presented in the present article. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
