Mental Work Load

Question 1

two theoretically well-based approaches and definitions of mental workload

Answer 1

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

Question 2

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

Answer 2

requirements resources interaction approach

Question 3

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

Answer 3

requirements resources interaction approach

Question 3

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

Answer 3

task requirements approach

Question 4

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.

Answer 4

task requirements approach

Question 5

Common characteristics of both conceptualizations

Answer 5

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.

Question 6

MWL and its consequences may be roughly categorized into three.

Answer 6

1. Underload
2. Perfectly Fitted Load
   3.Overload

Question 7

Underload: Boredom, Monotomy ; Overload:

Answer 7

Mental Fatigue

Question 8

proposed that resource theories might be subdivided into resource volume and resource allocation theories

Answer 8

Wieland-Eckelmann 1992

Question 9

The amount of available capacity may come from a single source which determines processing

Answer 9

single resource theories

Question 10

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

Answer 10

multiple resource theories

Question 11

suppose qualitatively changing processing as a function of varying strategies. Depending on the strategies, differing mental processes and representations may be applied for task accomplishment

Answer 11

Resource allocation theories

Question 12

most often discussed approaches try to assess MWL

Answer 12

1. effort assessment
2. mental capacity assessment

Question 13

Effort assessment: scaling procedures ; mental capacity assessment:___

Answer 13

dual task techniques

Question 14

The mental capacity assessment consists of the dual task techniques and a related data interpretation procedure

Answer 14

performance operating characteristic (POC)

Question 15

graphically illustrates the effects of
possible dual-task combinations arising from sharing limited resources among the concurrently
performed tasks.

Answer 15

POC curve

Question 16

multidimensional, a profile-like one, applying a
theoretically selected pattern of graded dimensions of task characteristics

Answer 16
