background: the effect of coping strategies on modification of competitive anxiety and self-confidence is controversial. the purpose of this study was investigation of the role of coping strategies on competitive anxiety and self-confidence in individual and group athletes. methods: 700 group and individual athletes were selected from five counties of kermanshah province, western iran, applying...

This paper describes the use of a collaborative envisioning tool to combine the goals of disparate communities concerning the role of new sensor technologies being deployed in Military Operations in Urban Terrain (MOUT). To do this, Cognitive Engineering intersects with the sensor development and military operations communities. Through the use of scenario-based design and the Topic Landscape t...

In this work, we investigate the effect of linguistic complexity on cognitive load in a dual-task scenario, namely simultaneous driving and language use. To this end, we designed and implemented a psycholinguistic experiment where participants use a driving simulator while listening to spoken utterances and answering comprehension questions. On-line physiological measures of cognitive load, inc...

In order to implement real-time adaptive augmented cognition, one of the focal points of our present research involves understanding the dimensions of task complexity. Task complexity is a construct that has been used in many fields such as biology, computer science, and psychology. An objective of our current research effort is to be able to instantaneously assess change in the cognitive capab...

A paradigm for the determination of time-accuracy functions (TAFs) for individual participants is introduced for two pairs of tasks differing in cognitive complexity, that is, word scanning vs cued recognition and figural scanning vs figural reasoning. TAFs can be used to test dissociations of cognitive processes beyond scale-related ambiguities of ordinal interactions. The approach is applied ...

Abstract While many studies have investigated the effect of task complexity on L2 writing, little has been reported effects intended manipulations task-generated cognitive demands in writing. This study, therefore, was designed to examine relative and students’ Two argumentative writing tasks were manipulated with varying numbers elements reasoning be distinguished either as a simple or complex...

There is ample evidence that individuals’ evaluation and choice of transportation-related alternatives in stated experiments vary by task complexity. Previous research has analyzed experimental error primarily as a function the number alternatives, attribute (levels) response time. It ignored fact cognitive ability individuals may be another important moderating variable. Another limitation pre...
