Abstract

Measuring workload accurately is critical for human factors research and applications. However, if the instruments we use to measure workload are burdensome for participants to complete, we may find ourselves in the ironic position of increasing workload simply by measuring it. We present a pair of studies that suggest the NASA-TLX, a widely-used workload metric, increases workload for participants who complete it, and consequently may hurt performance and upwardly bias the estimates it produces. We found that repeated administration of the NASA-TLX increased workload by 18%, and more than doubled the performance decrement on a simple vigilance task. Single-item measures may be a simple way to avoid burdening participants unnecessarily while still obtaining valuable insight into participant cognitive state. In line with the attentional resource theory, we validate a measure that asks participants to ‘think about [their] brain as an engine,’ and to indicate inside a rectangle ‘how much gas [they] h...

Abstract

Transcranial Doppler sonography (TCD) was used as a tool in human factors and neuroergonomics research as early as the 1990s. Prior to that it had been used in medicine for many years to assess and diagnose various aspects of cardiovascular dysfunction (Caplan et al., 1990). Since TCD's adoption in psychological research it has been used in studies examining visual and auditory processing, spatial processes, working memory, gender and age, language processes, and general attention. It has primarily been used in neuroergonomics research to examine workload and effort during vigilance performance. This chapter reviews a selection of the literature from the past decade. It begins with a brief overview of the technical elements and the logic underlying the use of the technique, and continues with a discussion of TCD's use within neuroergonomics to study various tasks, processes, and individual differences.

Abstract

Given that older adults are remaining longer in the workforce, their ability to perform demanding cognitive tasks such as vigilance assignments needs to be thoroughly examined, especially since many vigilance assignments affect public safety (e.g., aviation, medicine, and long distance driving). Previous research exploring the relation between aging and vigilance is conflicted, with some studies finding decreased vigilance performance in older adults but others finding no effect of age. We sought a better understanding of effects of age on vigilance by assessing neurophysiological change over the course of a vigil in young (aged 18-24) and healthy older (aged 66-77) adults. To measure temporal changes in cerebral blood flow, participants underwent functional transcranial doppler (fTCD) recording during a one-hour vigilance task. Based on research showing a compensatory effect of increased left hemisphere activation during vigilance in young adults and the ‘hemispheric asymmetry reduction in older adults’ (HAROLD) model, we predicted that during vigilance our older adults would show greater left hemisphere activation but perform at a similar level compared to young adults. While cerebral blood flow velocity (CBFV) declined over time in both groups, only young adults showed the typical right-lateralized CBFV pattern. Older adults showed greater left hemisphere activation consistent with the HAROLD model. However, the increased left hemisphere activation did not appear to be compensatory as the older adults performed at a significantly lower level compared to young adults over the vigil. Findings are discussed in terms of the HAROLD model of healthy aging and the resource theory of vigilance.
