چکیده

A preliminary set of analyses are presented, where workload was examined in 32 adults infected with the human immunodeficiency virus (HIV). Like current COVID-19 pandemic (caused by SARS-CoV-2 virus), HIV can produce a wide variety symptoms, including various levels cognitive dysfunction. In fact, recent meta-analysis estimates that 39 million globally HIV, 42.6% exhibit some form HIV-associated neurocognitive disorder. common symptom is decline attention and executive functioning. Though typically clinicians less precise traditional paper-and-pencil neuropsychological tests, we this aspect functioning using more psychometrically sophisticated task as had HIV-positive perform computerized tracking single, dual, tri-task conditions via Multi-Attribute Task (MAT) Battery. Also assessed mental workload, NASA-Task Load Index (NASA-TLX), rarely used neuropsychology but standard tool factors neuroergonomics research. As expected, performance declined condition difficulty ( p < 0.001). Although no direct statistical comparisons were made, MAT here appeared worse than other groups reported research literature our laboratory. Ratings also tended to increase function Plotting against Mental Demand subscale scores, large individual differences evident both optimal sub-optimal performance.

Modeling Mental Workload Via Rule-Based Expert System: A Comparison with NASA-TLX and Workload Profile

In the last few decades several fields have made use of the construct of human mental workload (MWL) for system and task design as well as for assessing human performance. Despite this interest, MWL remains a nebulous concept with multiple definitions and measurement techniques. State-of-the-art models of MWL are usually ad-hoc, considering different pools of pieces of evidence aggregated with ...

NASA TLX: software for assessing subjective mental workload.

The NASA Task Load Index (TLX) is a popular technique for measuring subjective mental workload. It relies on a multidimensional construct to derive an overall workload score based on a weighted average of ratings on six subscales: mental demand, physical demand, temporal demand, performance, effort, and frustration level. A program for implementing a computerized version of the NASA TLX is desc...
