When and Why Do Controllers Mark Flight Progress Strips? a Look at Live Traffic

Subject matter experts were employed to record observations of flight progress strip marking across 5 en route ATC facilities. Approximately 220 hours of ATC observations were recorded establishing a group of high frequency/high importance markings. These markings were perceived by controllers to provide performance benefits through externalizing memory and communication. The results are discussed in relation to possible electronic alternatives to flight progress strips.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

Age-related differences in dual-task search: understanding the role of component task learning in skilled performance

It is widely held among cognitive aging researchers that older adults are at a disadvantage with respect to the division of attention between two or more concurrent tasks. Some researchers have attributed dual-task performance decrements to reduced processing speed with age while others have attributed declines in dual-task performance to the reduced efficiency of task coordination and control processes. Few researchers, however, have considered the possibility that age-related differences in dual-task performance may be related to underlying differences in the learning mechanisms supporting component task performance. Three studies were conducted which differed in the type of single-task training provided to young and old adult participants: Consistently mapped (CM), variably mapped (VM) and attenuated priority (AP) training. Skilled dual-task performance was then assessed as a function of both component task learning and age through a) the examination of initial and end-level skilled dual-task performance, b) transfer of learning to novel task combination and c) retention capability. It was predicted that type of component task training would moderate age-related differences in skilled dual-task performance. The results were confirmatory, however, were not completely consistent with initial predictions.Ph.D.Committee Member: unknow
