| Abstract | This article presents two studies investigating how computer interface affordances influence basic cognition, including ideational fluency, problem solving, and inferential reasoning. In one study comparing interfaces with different input capabilities, students expressed 56% more nonlinguistic representations (diagrams, symbols, numbers) when using pen interfaces. A linear regression confirmed that nonlinguistic communication directly mediated a substantial increase (38.5%) in students' ability to produce appropriate science ideas. In contrast, students expressed 41% more linguistic content when using a keyboard-based interface, which mediated a drop in science ideation. A follow-up study pursued the question of how interfaces that prime nonlinguistic communication so effectively facilitate cognition. This study examined the relation between students' expression of nonlinguistic representations and their inference accuracy when using analogous digital and non-digital pen tools. Perhaps surprisingly, the digital pen interface stimulated construction of more diagrams, more correct Venn diagrams, and more accurate domain inferences. Students' construction of multiple diagrams to represent a problem also directly suppressed overgeneralization errors, which were the most common inference failure. These research results reveal that computer interfaces have communications affordances which elicit communication patterns that can substantially stimulate or impede basic cognition. Implications are discussed for designing new digital tools for thinking, with an emphasis on nonlinguistic and especially spatial representations that are most poorly supported by current keyboard-based interfaces. |

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.
