Study Notes
Mental Workload
Cognitive Load
- Definition: The amount of mental effort required to complete a task, influenced by the complexity of the task, the individual's prior knowledge, and the available working memory.
- Types:
- Intrinsic cognitive load: Caused by the inherent complexity of the task.
- Extraneous cognitive load: Caused by the way the task is presented or the environment.
- Germane cognitive load: Caused by the effort to create schemas and automate processes.
- Factors affecting cognitive load:
- Task complexity
- Prior knowledge and expertise
- Working memory capacity
- Attention and motivation
- Measurement methods:
- Self-report measures (e.g., NASA-TLX)
- Performance metrics (e.g., reaction time, accuracy)
- Physiological measures (e.g., heart rate, skin conductance)
Mental Fatigue
- Definition: A state of decreased mental performance and productivity, characterized by feelings of exhaustion, lethargy, and decreased motivation.
- Causes:
- Prolonged mental workload
- Insufficient rest and recovery
- Lack of autonomy and control
- High levels of stress and anxiety
- Effects:
- Decreased cognitive performance (e.g., attention, memory)
- Increased error rates
- Decreased motivation and engagement
- Increased risk of burnout and turnover
- Measurement methods:
- Self-report measures (e.g., Multidimensional Fatigue Inventory)
- Performance metrics (e.g., reaction time, accuracy)
- Physiological measures (e.g., heart rate, cortisol levels)
