Abstract
The article seeks to determine how time pressure and missing information in decision-making affect the behavior of decision makers. Data was collected through an experimental task of simulating the purchase of a car, which was structured with the AHP (Analytic Hierarchy Process) multi-criteria method in a Decision Support System. When pressured by time, the experimental subjects focused on the car of their choice; whereas with no time pressure, some of them rationalized more, used the information, and did not agree with the chosen car. Assumptions of the Theory of Image justified some findings, indicating that previously structured images in the mind of the decision maker are a way to cope with time pressure. Given the missing information, the use of background knowledge and individual experience were the most prominent coping strategy.

Whether operational or strategic, decisions are part of any human task
In Group 1, which performed the task with missing information and with time pressure, all experimental subjects opened the information cells of the AHP MAKH-ER by criteria (Figure 4), and in the order in which they were presented, i.e., starting in the first column and so on
Summary
Decisions are part of any human task. When examining the process of decision making in organizations, it is possible to note that it has been changing quickly in recent years, regarding the speed of advancement of information technology and communications. The changeability and dynamics of the environment in which companies act result in a new business environment: from the manager and the chief executive greater preparation for the establishment of strategies and decision making is required (Berto, 2004). When studying the decision-making process one should not fail to analyze the influences experienced by the decision maker during this process, since there are several behavioral factors that influence those expected to make the decision. The study on decision making in companies has been the subject of theoretical and management research, and much has been discovered and analyzed on the subject. Löbler & Hoppen (2005) add that research on the decision maker's behavior, human judgment, and choices currently aim at understanding how the human mind works in different situations and with different information, in addition to observing the results
