|Abstract||this paper examines. The second question, namely, which of the paradigms (if any) portrays the actual threshold, is more relevant but also more difficult to address, and it may well be that the attentional and memory load that spatial versus temporal paradigms demand make each of them unsuitable for addressing distinct subsets of research topics. In any case, the reasons that this second question escapes examination are that (1) empirically, we cannot collect dependable data that would allow a comparison with "true threshold" because all of our measured thresholds are suspect in these conditions and (2) formally, simulations cannot be carried out to address the issue in the absence of dependable and detailed quantitative knowledge of the particular effects of attention and memory (in spatial versus temporal presentations) on visual performance. Yet, the issue may be irrelevant from a practical point of view as long as thresholds obtained in spatial versus temporal paradigms keep a constant relation to each other and results obtained with spatial versus temporal paradigms in the same or different studies are not compared except to arrive at conclusions regarding differences in the outcomes of each paradigm. Since observing the latter admonition is entirely in the hands of practicing psychophysicists, the work reported in this paper set out to document the relation between thresholds obtained in identical conditions except for the spatial versus temporal arrangement of the 2AFC paradigm|

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.
