Transcranial Doppler sonography was used to measure cerebral blood flow velocity (hemovelocity, CBFV) from the left and right middle cerebral arteries during the performance of 40-min auditory and visual vigilance tasks. Reductions in stimulus duration were the critical signals for detection in both tasks, which were equated for stimulus salience and(More)
UNLABELLED This experiment was designed to assess cognitive load using transcranial Doppler sonography during the performance of a 40-min communication vigilance task in which messages were presented in different spatial locations or across a single monaural radio channel. In addition, some observers received 14 hours of practice to determine whether the(More)
Transcranial Doppler sonography was used to measure bilateral cerebral blood flow velocity during sustained attention task performance where the background event schedule occurred in a synchronous (temporally regular) or asynchronous (temporally irregular) manner. Perceptual sensitivity was greater in the synchronous case and declined over time in both(More)
OBJECTIVE In this study, we evaluated the validity of the Sustained Attention to Response Task (SART) as a means for promoting mindlessness in vigilance performance. BACKGROUND Vigilance tasks typically require observers to respond to critical signals and to withhold responding to neutral events. The SART features the opposite response requirements, which(More)
OBJECTIVE The aim of this study was to compare the effectiveness of a new index of perceived mental workload, the Multiple Resource Questionnaire (MRQ), with the standard measure of workload used in the study of vigilance, the NASA Task Load Index (NASA-TLX). BACKGROUND The NASA-TLX has been used extensively to demonstrate that vigilance tasks impose a(More)
Technological innovation increasingly requires operators in various applied settings to maintain vigilance for extended periods. However, standard psychometric tests typically predict less than 10% of performance variance. The present study (N = 462) aimed to apply the resource theory of sustained attention to construct a multivariate test battery for(More)
OBJECTIVE We assess the driving distraction potential of texting with Google Glass (Glass), a mobile wearable platform capable of receiving and sending short-message-service and other messaging formats. BACKGROUND A known roadway danger, texting while driving has been targeted by legislation and widely banned. Supporters of Glass claim the head-mounted(More)
OBJECTIVE We investigated performance, workload, and stress in groups of paired observers who performed a vigilance task in a coactive (independent) manner. BACKGROUND Previous studies have demonstrated that groups of coactive observers detect more signals in a vigilance task than observers working alone. Therefore, the use of such groups might be(More)
OBJECTIVE We tested the possibility that monitoring a display wherein critical signals for detection were defined by a stereoscopic three-dimensional (3-D) image might be more resistant to the vigilance decrement, and to temporal declines in cerebral blood flow velocity (CBFV), than monitoring a display featuring a customary two-dimensional (2-D) image.
