The user's cognitive construction of a task exemplifies a set of probabilities about what the outcome will be and what will lead to the outcome. With this in mind, we can see that the structure or layout of menus tends to focus on the user's cognitive construction. For example, when a person goes grocery shopping and when they check out and make payment for the purchased item, the person will pay in cash or use a credit or debit card. Once the person decides to pay with credit or debit card, in most cases after swiping the card the machine will ask if the person will pay with debit or credit. Also, if the person decides to pay by debit, the machine will ask whether the person wants a refund or not. The same can be said of an ATM. When using an ATM, the machine often asks if the person wants to make a deposit, withdrawal or checking account and much more. With this, we can say that menus are structures such that the flow assigns the individual or user a task to achieve their goal or objective. We can understand why it is essential for the user to be able to recognize the types of menu layouts and the logic in which the menus flow. 2.0 Menu Selection Many researchers have anticipated theories about the different approaches that people around the world use when they want to locate a recognized menu. item in an unordered list of options. Norman and Vandierendonck recommended that people should only be able to process one menu at a time. This idea or recommendation that people can only process one item at a time could be related to the sequential linear menu. However, they did not empirically authenticate the low-level hypothesis. Card SK, the author of "Visual Search of Computer Command Menus", proposed that people randomly choose which item t...... in the center of the paper...... see that for the most part , the arrangement of simultaneous menus overshadows sequential linear menu designs. However, the choices we can make in choosing what type of design should be based are not what your end users would like to see and do on a daily or weekly basis. It should be based on the type of business and the outcome you would like to achieve. For example, if you expect the user to be able to make multiple selections from two or more menus, it would be wise to use concurrent menu designs to improve performance. Also, if on the other hand you only want your target audience to use or make one choice at a time, sequential linear menus would be a good deal. Let's say for some reason you want your menu design to be used for investigative tasks, concurrent would be a good choice in that situation because it provides a continuous flow of summary.
