A Measurement Approach to Cognitive Complexity and Perception of Information: Implications for information Systems Design

摘要: > Business decision makers were asked to evaluate and use various information reports, as might be supplied by an system, in several making scenarios. Multi-dimensional scaling was utilized detect underlying perceptual dimensions of the (differentiation ability), assess importance or salience placed on each these (discriminant ability). Preference mapping rules used using items tasks. As expected, individual differences found with respect differentiation, discrimination, integration abilities. However, further analysis demonstrated that relatively homogeneous groupings could formed which a similar manner.
