Mental Workload in Neuropsychology: An Example With the NASA-TLX in Adults With HIV

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. To examine likely variables potential impact on Demand, (nadir CD4 count, viral load, depression diagnosis AIDS, presence opportunistic infection, general status, etc.) relation scale, age showing significant association r = 0.41, 0.022) AIDS trend associations s ≥ 0.066). Findings suggesting deficit metacognition or insight discussed. It argued assessment (and its aspects components) provide valuable additional information neuropsychology.

متن کاملModeling 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 ...

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...
