Abstract | Motivation -- To analyse human errors and determine the underlying reason for these errors, in particular by investigating the error production mechanism cognitive lockup. Research approach -- A within subjects experiment has been conducted with 16 pilots in a high-fidelity and realistic environment. The independent variables were the cognitive task load factors time pressure and number of tasks, and the task variable task completion. In addition, the pilots rated the effort it took them to handle the tasks. To evaluate whether cognitive lockup occurred, the time it took the pilots to start handling a new, high-priority task was measured. Findings/Design -- The results suggest that the cognitive task load factors, and the effort they induce in the pilots when executing the task, increase the likelihood of the occurrence of cognitive lockup. Research limitations/Implications -- Investigating cognitive lockup empirically is limited, as it is a phenomenon rarely observable. Originality/Value -- The research makes a contribution to understanding why pilots deviate from normative behaviour and with this to make it possible to improve the safety of operations on aircrafts. Take away message -- The error production mechanism cognitive lockup might partially be explained by a high cognitive task load, produced by time pressure and a high number of tasks. |

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.
