Enhancing Effective Decision Making by Information Management Techniques
Abstract
Four experiments varying in complexity of decision tasks were conducted to study the effects of information about expected length of task on decision processes and choices. All experiments utilized a combined between and within subjects design with two initial levels of information (long vs. short expected list of items) and subsequent information change (reducing the long and increasing the short). In two experiments, a computerized process methodology provided detailed data on information search, speed, and strategy used. Individual differences were tested using a battery of personality characteristics. The results indicated that initially encouraging information enhances the quality of decision processes, particularly during the first phase of the task. The impact of information change was less prominent, although it produced full reversals in several indices of decision performance. Personality characteristics interacted with the information manipulations. The role of cognitive resource allocation in decision tasks and several practical implications are discussed.
