Sample interview questions: Can you explain the concept of mental workload and how it can be measured?

- Concept of Mental Workload:
- Mental workload refers to the cognitive effort an individual expends to complete a task or a set of tasks.
It involves various mental processes such as perception, attention, memory, decision-making, and problem-solving.
Mental workload is affected by factors like task complexity, time pressure, information load, and individual differences.
High mental workload can lead to fatigue, stress, decreased performance, and even errors.
- Methods for Measuring Mental Workload:
- Subjective Measures:
- Questionnaires and surveys that directly ask individuals about their perceived mental workload. Commonly used methods include:
- NASA-Task Load Index (TLX)
- Subjective Workload Assessment Technique (SWAT)
- Workload Profile (WP)
- These methods provide self-reported data on workload, but may be influenced by factors like individual perceptions and attitudes.
- Questionnaires and surveys that directly ask individuals about their perceived mental workload. Commonly used methods include:
- Subjective Measures:
Behavioral Measures:
- Measurements of performance outcomes, such as task completion time, error rates, and response latencies.
- High mental workload may be indicated by slower reaction times, increased errors, and reduced task efficiency.
Physiological Measures:
- Monitoring physiological responses associated with mental workload, such as heart rate, heart r… Read full answer
