People chose different strategies for performing tasks, and that choice often plays a key role in performance. We investigate the use and evolution of strategic behavior in the Kanfer-Ackerman Air Traffic Controller c task, a fast-paced, dynamic task. We present strategies in two dimensions for one aspect of the task, examine how people use them and switch between them, and how their use relate...

This paper begins with a discussion of two features of the everyday task environment. First, the everyday task environment is designed, and an important part of the design is the provision of explicit information to guide the individual in the adaptation of his activity. Second, some task environments are semipermanent. These two features of the task environment reveal some important characteri...

Instructors play a major role in many of the current virtual training systems. Consequently, either many instructors per trainee are needed, which is expensive, or single instructors perform highly demanding tasks, which might lead to suboptimal training. To solve this problem, this paper proposes a cognitive model that not only generates the behaviour of virtual characters, but also produces e...

BACKGROUND AND PURPOSE Most mental screening tests focus on the detection of cognitive deficits compatible with Alzheimer's disease. Stroke patients who develop a dementia syndrome, however, constitute a more heterogeneous group with both cortical and subcortical disturbances. We assessed the diagnostic accuracy of the CAMCOG (the cognitive and self-contained part of the Cambridge Examination f...

In this paper, we discuss the human thematic fit judgement correlation task in the context of real-valued vector space word representations. Thematic fit is the extent to which an argument fulfils the selectional preference of a verb given a role: for example, how well “cake” fulfils the patient role of “cut”. In recent work, systems have been evaluated on this task by finding the correlations ...

Adaptation capabilities are becoming more and more popular in applications due to several facts, including heterogeneity of users, devices and physical contexts of use where applications are currently used. Adaptation is not per se good, and poor adaptations usually lead to disappointed users that reject or disable adaptation mechanisms. Therefore, in order for adaptation to reach the mainstrea...
