Mental Work Load Flashcards

1
Q

two theoretically well-based approaches and definitions of mental workload

A
  1. MWL as viewed in terms of the task requirements as an independent, external variable with which the working subjects have to cope more or less efficiently
  2. MWL as defined in terms of an interaction between task requirements and human capabilities or resources

Q

was developed within the context of personality environment fit/misfit theories which try to explain interindividually differing responses to identical physical and psychosocial conditions and requirements

this approach may explain
individual differences in the patterns of subjective responses to loading requirements and
conditions, for example, in terms of fatigue, monotony, affective aversion, burnout or diseases

Q

was developed within those parts of occupational psychology and ergonomics which are predominantly engaged in task design, especially in the design of new and untried future tasks, or so-called prospective task design

Q

an approach that tries to answer the question of how to design tasks in advance in order
to optimize their later impact on the—often still unknown—employees who will accomplish these
future tasks.

Q

Common characteristics of both conceptualizations

A
  1. describes the input aspects of tasks
  2. conceptualized in terms of information processing
  3. Information-processing integrates mental processes, representations, and states
  4. MWL is a multidimensional characteristic of task requirements
  5. will have a multidimensional impact
  6. MWL should not be minimized, but optimized
  7. must be dealt with in task analysis, task requirement evaluation as well as in corrective and prospective task design.

Q

suppose a set of relatively independent processing resources. Thus, performance will depend on the condition whether the same resource or different resources are required simultaneously and concurrently
