The research objective was to evaluate cerebral blood flow velocity's (BFV) sensitivity to performance changes in a multitasking setting and to examine resulting constraints on multitasking. The research used a Transcranial Doppler Sonography (TCD) unit and multitask environment simulation. The tasks represented the diverse nature of the future military environment and included visual tracking, auditory monitoring, and more complex cognitive tasks requiring mental manipulations and memory. Participants completed four tasks simultaneously but with varying priority. BFV and multitask performance were measured. Results showed that BFV changed during training and paralleled a performance change. BFV was not sensitive to changes in task load during multitasking. We did show behavioral consequences to multitasking, specifically when transitioning between tasks. The data suggest that BFV may not be the most direct neurophysiological method for measuring complex cognitive performance; however, the use of this type of portable and relatively low-cost methodology should be pursued further.

AbstractHow sure are we about what we know? Confidence, measured via self-report, is often interpreted as a subjective probabilistic estimate on having made a correct judgement. The neurocognitive mechanisms underlying the construction of confidence and the information incorporated into these judgements are of increasing interest. Investigating these mechanisms requires principled and practically applicable measures of confidence and metacognition. Unfortunately, current measures of confidence are subject to distortions from decision biases and task performance. Motivated by a recent signal-detection theoretic behavioural measure of metacognitive sensitivity, known as meta-ď, here we present a quantitative behavioural measure of confidence that is invariant to decision bias and task performance. This measure, which we call m-distance, captures in a principled way the propensity to report decisions with high (or low) confidence. Computational simulations demonstrate the robustness of m-distance to decision bias and task performance, as well as its behaviour under conditions of high and low metacognitive sensitivity and under dual-channel and hierarchical models of metacognition. The introduction of the m-distance measure will enhance systematic quantitative studies of the behavioural expression and neurocognitive basis of subjective confidence.

As the complexity of aircraft cockpit operations increases, training effectiveness must be improved, and learning accelerated. Virtual reality (VR) training is increasingly offered as a method for improving training efficacy given its ability to provide a rich sensory experience during learning. This paper describes a study examining how training efficacy can be improved by improving learning diagnostics. We study how varying forms of knowledge assessment are related to different types of task knowledge and task performance in a VR flight simulator. The data suggest that participants who demonstrated higher training comprehension, measured via diagnostic test questions, on conceptual (and to a lesser effect) declarative knowledge, also demonstrated superior knowledge transfer in the VR flight simulator. Findings are discussed in the context of improving cognitively diagnostic assessments that are better able to predict task performance and inform individually tailored training remediation.

Researchers have suggested that task performance is often dependent upon the congruence of cognitive style and task. To explore this suggestion, 44 female and 4 male undergraduates were administered the Cognitive Style Analysis, the Closure Flexibility, the Composite Gestalt Completion Test, and the Vocabulary subtest from the WAIS. Specifically, four hypotheses were tested: (1) that participants with an analytic style will perform better than those with a wholistic style on the Closure Flexibility; (2) that participants with a wholistic style will perform better than those with an analytic style on the Composite Gestalt Completion Test; (3) that participants with an intermediate style will outperform persons with an analytic style on the Composite Gestalt Completion Test; and (4) that intermediate scorers would perform better than those with a wholistic style on Closure Flexibility. Only the second hypothesis was supported, so results provide only minimal support for the effect of match or mismatch of cognitive style and task performance.
