Methods for Predicting Job-Ability Requirements: 3. Ability Requirements as a Function of Changes in the Characteristics of a Concept Identification Task. Technical Report No. 3.
Fingerman, Paul W.; And Others
This report describes the third study in a program of research dealing with the relationships between the characteristics of human tasks and the abilities required for task performance. The goal of the program is to generate principles which can be used to identify ability requirements from knowledge of the characteristics of a task and of variations in the conditions of task performance. The study investigated the relationship between variations in a prototypic problem-solving task, concept identification, and consequent changes in the abilities related to problem-solving performance. Characteristics of the problem-solving task were manipulated by varying the formal difficulty and perceptual complexity of the problems. Subjects performed the criterion task under the different experimental conditions, and then received a battery of reference tests designed to measure abilities which were hypothesized to relate to problem-solving performance. The test battery was factor analyzed to identify a reference ability structure. The loadings of the various criterion task conditions on that structure were then estimated. Results suggested that certain task variations change the nature of the task in such a way that subjects change their approach or strategy for dealing with the task. Such changes may require different ability profiles; thus they may account for changes in abilities related to performance as a function of changes in task characteristics. Further analysis is planned to examine the interactions of task variation, subject strategies, and ability profiles. (Author/BJG)
