IE16 Ergonomics 2: Mental Workload

The cognitive demands placed on an individual by a task, affecting performance and comfort.

The mental effort required to complete a task, influenced by complexity and resource availability.

Factors that increase the mental load, requiring higher cognitive effort from workers.

The impact of cognitive demands on an individual’s mental resources and overall performance.

The level of difficulty of a task, which affects the amount of cognitive resources needed.

Excessive amounts of information that exceed cognitive capability, resulting in reduced performance.

The mental capacity available to focus on tasks; limited and can become depleted.

Reduction in task performance effectiveness when cognitive demands exceed available resources.

Methods used to assess mental workload, such as subjective ratings and physiological indicators.

A physiological indicator used to assess workload by measuring fluctuations in heart rate.

Personal assessments of workload often collected after tasks to gauge mental demand and strain.

A well-known subjective workload assessment tool measuring various mental demand aspects.

The ability of a measurement technique to detect changes in mental workload across different tasks.

Consistency of measurement outcomes over time, ensuring accurate comparisons.

The degree to which a measurement technique interferes with primary task performance.

A structured battery of tasks designed to evaluate cognitive performance and workload.

The distribution of limited mental resources to different tasks based on demand.

The effectiveness with which an individual carries out a main task under specific conditions.

Assessments made after task completion to gauge mental workload perception.

Verbal or other assessments taken while performing tasks to gauge current mental workload.

Secondary tasks integrated into operational settings to assess workload without major interference.

Bodily indicators, like heart rate, used to assess workload without heavy cognitive demands.

The process of directing focused mental energy towards specific tasks or stimuli.

A framework outlining how cognitive capacity is affected by task demands and learner experience.

Real-world settings where tasks occur, impacting workload assessment techniques.

Frequency of mistakes made during various tasks, often linked to mental workload levels.

The relationship between human cognitive processes and multiple task demands in sophisticated environments.

The overall health and comfort of an employee, improving through effective workload management.

Strategies aimed at reducing mistakes by optimizing workloads and task designs.

The integration of knowledge from different fields to enhance understanding of mental workload.
